Android Zero

Android Zero (人造人間号0 Homunkurusu-gō 0, lit "Android 0") is a Bio-Android created by Dr. Gero as a prototype to Cell. His DNA mainly consists of Android 17 & 18, and has extensive knowledge of the greatest fighters on Earth due to simulations being transferred into his brain during development.

He was initially created, like the other androids, for the sole purpose of killing Goku. But, like his brother and sister, one of his biggest flaws was that he possessed emotions, and free will, that's why Dr. Gero raised him from birth to be obedient, and emotionless as possible.

Future Trunks used the Dragon Balls to wish him into the future to help him protect time itself.

Appearance
Android Zero looks very similar to his brother and sister, Androids 17 & 18, although, slightly shorter.

Due to his extremely fast growth and lack of sunlight, Android Zeros skin is completely white; similar to Android 19.

His has a slim, but muscular build, dark green eyes, brown parted hair, and black stud earrings.

He would commonly wear an all black gi with a maroon belt, up until he started wearing Time Patroller gear, which included a grey, short sleeved jacket, with an orange collar, that was kept together by a belt. Underneath he wore and all black, skin tight, bodysuit that cut off half way down the calf. He wore long white gloves, and soft white boots, with black tips.

Personality
Being sheltered during the developmental periods of his life, Android Zero was blank a lot of the time. He did whatever Dr. Gero instructed him to do.

He tends to keep to himself, and can be rather shy. Nonetheless, he is very quick on his feet to come up with solutions to any kind of conflict.

Until he started going back in time, and helping people, he didn't know something like 'compassion' existed.

After a year of living in Toki Toki City, and defending time, Zero understood what it was like to care about people and have friends. Though still reserved, he is quite humble.

Background
After the Red Ribbon Army is defeated by Goku (Age 750), Dr. Gero goes into hiding in his laboratory located in a mountain area north of North City. In this lab, he strives to create the ultimate fighting machine. Using an extremely intelligent tracking device disguised as a ladybug, he studies Goku and the Z Fighters for years, observing the fights Goku has with Tien Shinhan, King Piccolo, Piccolo, and the Saiyans Raditz, Nappa and Vegeta.

Dr. Gero ceases the study of Goku's power when the Saiyan leaves for Namek, (Age 762) believing he had already compiled enough information; so he simply adjusts the androids power levels to accommodate for Goku's expected power increase, not accounting for the power level of Goku's Super Saiyan form. Believing he had created the ultimate fighting machines, he finalizes his plans and constructed a series of Androids.

While looking for fresh material for his experiments, Dr. Gero meets two notorious delinquents by chance, two siblings, a boy and a girl. He then kidnaps them and restructures them into Android 17 and Android 18. While constructing the Androids, Dr. Gero discovers a way to fuse together the cells from the strongest warriors to walk the Earth (Goku, Piccolo, Vegeta, Frieza, and King Cold), and tries to create a supreme fighting entity. After realizing that his project would take too long to complete, he decides to turn attention to other matters and leave his supercomputer from his lab to complete the ultimate being, who he names Cell. He did however start on a prototype bio-android to see if it was possible. By taking the human DNA of Android 17 & 18, with a little leftover DNA from the Cell experiment, and fusing it with an artificial human egg. This started the process of "growing" Android Zero.

Simulations and images of the greatest warriors on Earth were being transmitted into the developing brain of Android Zero. Growth hormones and other drugs were used to speed up the "pregnancy" resulting in the baby being born in 3 months, and with the maximum strength of an adult male.

Dr. Gero raised and trained Android Zero until Age 767 when he was 4 years old and fully developed into an adult body. This was timed perfectly for when Android 19 & Dr. Gero chose to reveal themselves thus starting the "Androids Saga" But on that day, something happened. In a future timeline, a wish was made...

Dragon Ball Xenoverse
After witnessing several disruptions in the timeline caused by Dark Frieza, Dark Cell, & Dark Kid Buu, Future Trunks summons Shenron wishing for a strong ally, one with the power to defend time itself. Android Zero is transported to Age 850 where Future Trunks immediately attacks to test the confused Androids strength, and engages him in battle. Following the fight, Trunks introduces himself and explains that Zero was summoned here by a wish from Shenron to Toki Toki City, a city where hundreds of people from different universes and timelines have gathered together to defend time, and to work alongside one another as members of the Time Patrol. Android Zero is perplexed; he has no idea what this man from the future is talking about. He's never seen anyone besides Dr. Gero and the androids in his lab, now he was in a bustling future city. Before Zero could say anything, Trunks tells him to follow him somewhere.

Saiyan Saga XV
Android Zero is lead to the Time Storage Vault by Trunks. Zero is shocked by the scenery. He had never seen vegetation before, everything was so green. Trunks gives Android Zero his first mission. Zero would be sent back in time to Age 761 where he would see some familiar faces, faces of people that have been burned into his memory.

When he arrives, he sees Goku, Piccolo, a young Gohan and Raditz. Android Zero was raised to hate these fighters. He was raised to kill them, specifically Goku. He recognizes the setting he's in. He has been to this very spot before in his dreams. He knows killing Goku right now won't complete his mission.

Zero see's that Raditz is about to kill Gohan with an energy blast but pushes the young Gohan out of the way. A single jab to the stomach subdued Raditz, allowing Goku to latch onto him for Piccolo to use his Special Beam Cannon. Android Zero stands and watches the all to familiar scene unfold. He see's Goku die, but knows that he will return.

After history is restored, Future Trunks congratulates the future warrior on a good job, with no negative side effects on history. Later, Android Zero is sent to aid more familiar faces (Yamcha, Tien Shinhan, Chiaotzu and Krillin) in their brawl against hordes of powered up Saibamen, a couple Tennenman, and a Jinkouman. Although things look good at the start, Zero is separated from the group, resulting in the deaths of Tien Shinhan, Chiaotzu, and Yamcha, not that he cared.

Succeeding in killing off all the Saibamen with a volley of ki blasts, Nappa steps in only to be knocked down by Android Zero. After seeing he is no match for Zero, Nappa tries to kill Gohan with a Bomber DX, with Piccolo stepping in to save his life by sacrificing his own. Nappa is instantly rejuvenated by a surge of dark energy. Vegeta fights Goku and leaves Nappa to his own. Zero, for the first time in his life saw in person what it was like for someone to sacrifice themselves for another. He noticed that he felt a new emotion inside himself, but was unsure of what it was. He felt a familiar emotion though, he felt anger, but didn't understand why. Looking down, and still pondering this internal conundrum, he lifts his hand, and fires a powerful ki blast killing Nappa. He then sets his sights on Vegeta, easily defeating him.

Vegeta is perplexed. he doesn't understand how he is being bested right now. In a last-ditch effort, Vegeta Turns into a Great Ape. Zero cuts off Vegeta's tail with a destructo disc, and then prevents Krillin from attempting to kill the Saiyan prince to avoid a timeline alteration, with Goku agreeing. Once back at the time nest, the Future Warrior meets Chronoa 'The Supreme Kai of Time' and her ancient pet, Tokitoki.

Namek Saga XV
The next day, Future Trunks finds another disturbance in the timeline and asks Zero to correct it. Joining the Z-Fighters on Namek, Age 762, December 24 Android Zero helps Vegeta fight an empowered Captain Ginyu until Recoome steps onto the field. After Recoome was almost killed by Zero with an energy blast, he leaps up and attempts to destroy the battlefield with his Recoome Ultra Fighting Bomber, before being swiftly interrupted by Goku. This is a new frontier for Android Zero. He has never seen Namek in any of the simulations. He knows Goku lives past this time period though, and thinks to himself, "this is a good time to kill him." Before he could do that though, Captain Ginyu hits him with a Body Change blast.

Zero is now in the significantly weaker body of Captain Ginyu and has to fight Burter and Jeice, who have now joined the battle.. Ginyu fights with Goku in the body of Android Zero, but only at a fraction of the new bodies full power; as he had to adjust to the new bodies energy. After Zero defeats Burter and Jeice, Goku asks Zero to check in on Krillin and Gohan at Frieza's spaceship, as him in Ginyu's body would let them go on board the ship with no hassle. Since Zero was unaware of his bodies full power, he agrees.

Zero, Gohan, and Krillin fight against Raspberry & Nabana, before, Guldo, Appule, and Navel enter the ship. At first, Guldo is surprised that his "Captain" is attacking him, though he eventually realizes that Ginyu must have performed a body swap. Guldo seeing he is loosing, flies away leaving his henchmen to defend the ship.

Once the trio gather the Dragon Balls, Ginyu (in Android Zeros body) and Goku arrive on site to continue their fight. After Goku & Zero both weaken Ginyu, he tries to swap with Goku again, but Zero jumps in-front of the beam to be restored into his original body. However his body has been beaten from Zero and Goku fighting it.

Guldo suddenly appears and freezes Goku with telekinesis long enough for Ginyu to body swap with Goku. Vegeta joins in to fight Guldo while Zero and Goku (now in Ginyus body) fight against Ginyu (inside Gokus body). Vegeta ends up executing Guldo, and the weakened Zero and Goku defeat Ginyu. Once Ginyu in Goku's body is beaten and battered, Vegeta tries to finish Ginyu off. Ginyu tries to take advantage of the opportunity and swap bodies with Vegeta, but Goku leaps in the way. Ginyu tries to swap again, but Goku tosses a Namekian Frog in the way, trapping Ginyu in a useless body.

Future Trunks speaks to Zero telepathically and tells him that the cause of the time distortions are near. Curious, and feeling too weak to kill Goku, Zero goes to find the cause. He then locates the cause of the distortions, Mira and Towa. Mira wants to test Android Zeros power and challenges him to a fight. Mira is the most powerful opponent Zero has ever faced, and he knows he's barely trying. After a brief fight, Mira is not remotely intimidated and is ready to steal the Warrior's energy, until Towa stops him, and says they have better business to attend to.

Later, at the Time Nest. Future Trunks and Android Zero talk about what happened and wonder who the mysterious duo, Towa & Mira are. Chronoa walks over to them and explains that Towa is the little sister of the Demon King, Dabura, and Mira is a warrior she created. Together, they are stealing strong warriors energy throughout time in hopes of releasing the seal on the Demon Realm. If the Demon Realm is open, then the balance of the entire universe will collapse.

Trunks is then interrupted by an all too soon disturbance in time. Chronoa quickly heals Zero, and asks him to go an check out the distortion, immediately.

Frieza Saga XV
Android Zero is sent back in time to a very aggravated Frieza facing off against Gohan, Krillin, and Vegeta.

Zero uses a lightning quick punch to the gut that brings Frieza to his knees. Trying to catch his breath, the tyrant reveals he has three more transformations. However, the unseen interferes which leads Frieza to skip to his final form.

Piccolo arrives to Namek only to see he has no chance in beating Frieza in his fourth form. The healed up Goku shows up shortly after and begins to fight with Frieza. Goku yells to Zero that he's not powerful enough to defeat the enhanced Frieza, and asks to stall him while he generates enough power for a spirit bomb. Zero can sense a great power inside of Frieza, and is unsure if he has the power to kill him by himself, so he appears behind Freiza and holds him in a full-nelson while Goku charges his attack. After the attack is launched, The struggling Frieza takes the full force of a spirit bomb.

Goku and his friends celebrate the defeat of Frieza, with Android Zero silently watching from afar. That is, until a death beam exits through Piccolo's chest. Frieza is now surrounded in a dark purple aura with red glowing eyes. Zero senses he is significantly stronger. The powered up Frieza then flings Krillin into the air and causes him to explode. This act pushes Goku over the edge, causing him to become a Super Saiyan.

Zero and SSJ Goku easily beat around Frieza, until the monster sets to destroy Namek with a Death Ball. The two fighters than face Full Power, dark magic empowered Frieza on the dying planet 'Namek'. This is the strongest enemy Zero has faced since Mira, but this would be a battle to the death. This was to fix history. Luckily the Super Saiyan Goku was there to help in the battle. Frieza's dark aura disappears as he is now weakened and back to normal.

Goku sees Porunga and asks Zero to leave Frieza to him, but not before saying, "I really don't know much about you, but you really helped me out." Android Zero is unsure of how to feel about this. Why is his biggest enemy being kind to him? He will need to think on this.

Back at the Time Nest, Trunks, and Chronoa ponder on why Towa & Mira didn't show up to the battle with Frieza. Zero tells them that he used his full power in that battle, and if it wasn't for Goku being there, he would have lost. He tells him he needs to get stronger. He also reveals to them that he was created with the sole purpose of killing Goku. Chronoa and Trunks look at each other, then back at Zero and say, "we know." Zero is surprised by this, he asks them why they would allow him to go back in time where he could have easily killed Goku multiple times? Trunks tells him that he can sense good inside of him, and that he trusted that he would do the right thing.

After Zero and Trunks return to Toki Toki City, Trunks and also reveals something. He told Zero that the reason he started the Time Patrol was because he went back in time to save his own timeline, and feels selfish about it. The Time Patrol is a way to atone for his sins of the past. He tells Zero, "Shenron chose you out of the countless fighters in the universe and throughout time. I know I can count on you. Anything that comes our way we can handle it." Zero feels uncomfortable by the kindness that he was showing him. Trunks recognizes this and with a smirk says, "lets go train."

Cell Saga XV
After a couple weeks of training, another corrupted time scroll appears. Trunks appears to be frightened. He tells Android Zero he'll have to fight Cell; one of the strongest opponents he's ever faced. Zero has heard about Cell from Dr. Gero. He knows that he was a prototype to Cell. Android Zero, knowing full well he could be destroyed, is sent to prevent Mr. Satan from being killed by Perfect Cell. After saving Mr. Satan's life through unconventional means, the time traveler attempts to fight Cell.

Cell is much stronger than Android Zero, his attacks do nothing to the superior bio-android. Mr. Satan rushes in and tries to "finish off" Cell before being casually slapped out of the ring. While Mr. Satan writhes on the ground, Future Trunks chimes in that all is well, until Mr. Satan suddenly stops and gets up. Filled with dark magic, Mr. Satan actually flies back onto the ring. While Goku flies in to fight Cell, Android Zero goes over and knocks out the enhanced, but still incredibly weak, Mr. Satan.

Cell says, "Alright, there will be no more out-of bounds" destroys the ring, and continues to fight Goku.

Goku stops mid-fight and says, "I learned how strong you really are! That's it. I quit. Gohan! It's your turn, son." Gohan is understandably nervous and pleads with Cell not to fight, but it's inevitable.

After Gohan has proven to be a worthy opponent to Cell, his eyes begin to glow red and the sinister purple aura surrounds him. He creates 6 [https://dragonball.wikia.com/wiki/Cell_Jr. Cell Jr.'s] with the same purple aura and sicks them upon Zero, but not before Yamcha and Tien join the fight.

The Z Fighters aren't a match for the enhanced Cell Jr.'s. The miniature Cells are just toying with them. Suddenly, a massive burst of energy occurs. Gohan is forced into a Super Saiyan 2, but is surrounded by dark energy. Zero see's this as his chance to attack the Cell Jr.'s while they're off guard.

During Zero's training with Trunks, he worked on a move he saw Goku do. The Kaio-ken technique. Trunks explains to Zero, that he's only seen Goku capable of such a move, and that the technique was invented by King Kai. The user is able to multiply their ki for a "heart beat" - thus increasing their power and speed and enabling them to inflict serious damage to opponents who are considerably stronger than them. However, the downside of the Kaio-ken is that it takes a heavy toll on the user's body, essentially draining the users power. Still, Android Zero was determined to master the technique.

Android Zero notices at the right angle, the distracted Cell Jr.'s are lined up perfectly. Knowing this is the only way to defeat the foes, he powers up his body to Kaio-ken x20 and unleashes a mighty kamehameha disintegrating the aligned Cell Jr.'s. Android Zero then falls from the sky and plummets into the ground. The Kaio-ken technique completely depleted his energy.

Zero is woken up by a Senzu Bean being put in his mouth, with Trunks: Xeno standing over him. Trunks tells Zero that he's found Towa and Mira's location. Zero, being confused, asks what he's doing here, and he says that, "since Mira and Towa are outside the flow of time, fighting them won't affect our history." Trunks and Zero fly over to confront the Time Breakers.

Towa seems surprised to see Trunks, but welcomes the chance to steal the energy of another strong warrior. Trunks powers-up to a Super Saiyan 2, and the duo begin to fight Mira.

Though a tough fight, the two manage to "beat" him. Mira simply rises again and begins to power up until Towa interrupts and says they're done for the day. After taking a loan from Gohan's energy banks, they retreat. During the battle with Mira, Perfect Cell entered into his self-destruction form in a last ditched effort to destroy everyone on earth, but not before Goku instant transports them both to King Kai's Planet. Cell of course comes back to earth stronger, as Super Perfect Cell. Android Zero then steps in to help the weakened Gohan fight off powered up, Super Perfect Cell.

Zero knows he is no match for his seemingly, infinitely stronger opponent. So he buys time until Gohan can regain his energy. He tells Cell how Dr. Gero created him as a prototype for the "supposedly" ultimate being Cell, but he's not impressed with the final product. He berates Cell for almost being beaten by a child, and says if he wishes, he could defeat him with one hand behind his back. Cell only laughs at this. Zero can see his gab isn't doing the trick, so he powers-up to full strength and says, "this is only a fraction of my true power! You think you're so strong? I bet you can't even take a single punch from me at my strongest!" Cell wanting to test out his new strength welcomes the opportunity. Zero has no other choice, he powers up to Kaio-ken x20 and flies at Cell with all his strength, landing a perfect punch in the center of Cell's chest.

Cell is moved back a couple of feet. He looks at the inferior bio-android with disappointment and say's, "how pathetic. You were only half my strength." He grabs Android Zero by the throat, puts his hand to his face, and powers up a ki blast.

Just as he's about to kill Zero, Cell is hit with a powerful kamehameha. But not just any kamehameha, a Father-Son Kamehameha. Zero can sense Goku's energy, but can't see him. It seems to all be coming from the young Gohan. Still, the energy wave seems to not be doing anything to the enhanced Cell.

The wave starts moving towards Gohan. Zero is shocked by the strength of Dr. Gero's ultimate creation, if he didn't do something, time itself would be destroyed.

Android Zero flied behind Gohan and uses every last bit of energy to turn Kaio-ken x20. He was going to destroy Cell, even if it would kill him. He fires off a x20 kamehameha, adding to the already massive energy wave. The huge blue light is now moving towards Cell, eventually enveloping him, and restoring time.

Zero blacks out.

Androids Saga XV
Android Zero wakes up a week later by Trunks. He said that there is another distortion and it needs to be checked out immediately.

Android Zero, still feeling weak, follows Trunks to the Time Nest, and looks at a scroll from Age 783. The scroll shows none other than Trunks, but instead of saving his timeline, he's killed by Zero's own family, Android 17 and 18

Android Zero knows this would have been the path he'd have taken if it wasn't for being wished into the future. Even though he never met his brother and sister, he still felt close to them. He was sad that'd he'd have to defeat them in battle, and wished there was another way.

All of a sudden, Trunks starts to turn transparent. Him dying in the past is affecting him in the present. Chronoa explains that Towa must have went back to a crucial moment in Trunk's life to try and stop him from interfering with their plans. Understandably, Trunks tells Zero to go now, before he vanishes.

Android Zero arrives in the past to battle with his brother and sister. Both of them are surrounded in dark energy, and both out classing the still weakened Android Zero. Still, Zero needed to restore time so Trunks isn't killed.

The fight isn't pretty; Android 17 and 18 are beating both Zero and Trunks to a pulp. Zero fears that if he even attempts to use the kaio-ken technique again so soon, that he'll die, which means so will Trunks. The situation is grim, Trunks is knocked out of his Super Saiyan form by Android 17. Android 18 has Android Zero pinned under her foot ready to execute her little brother. The white skinned Android Zero is feeling helpless. He starts to think. He tries to remember the feeling of the energy used during Kaio-ken. The feeling of multiplying your energy. All of that has to come from within. Android Zero closes his eyes and starts to focus his ki throughout his body. Android 18 says, "looks like you're giving up" and fires a pink energy blast into the face of Android Zero.

As the smoke clears, She shockingly notices not a single mark is left on her pale opponents face. In-fact, he looked different. His hair had a slight orange tint to it and was standing straight up. He had a pale yellow aura surrounding him. Android Zero opens his eyes to reveal his pupils had all but disappeared. Android Zero uses an explosive wave to launch his big sister off of him and sends her flying. Android 17 now aware of the powerful threat has no time to react before Zero knocks him away from the beaten Trunks. It seems the evil androids had retreated for the day, but before Future Trunks could thank his savior, he was already gone.

Towa appears in-front of Android Zero, and mocks the time warrior. She says, "I bet you actually thought you helped him...am I right? You see, I actually made two changes." Trunks: Xeno communicates that he's still disappearing, and history hasn't been corrected! Towa laughs and says, "there's nothing you can do" and vanishes. Android Zero had been outplayed. There was nothing more he could do.

"You seem to be troubled." A voice is heard directly behind Zero. He turns around to see someone he's never met. A demon, by the looks of it, holding a bone staff, with big red hair, and skin almost as white as Zeros. "Would you like to go to the change?" he asks, "I'll take you there" as he holds out his hand. "You don't have any other choice." Zero seeing no other options reaches out and touches the mysterious strangers hand. before Android Zero is transported, the demon says, "Tell the Supreme Kai of Time...that I'll see her soon."

Android Zero is transported to Age 785. This is when Future Trunks returned to his timeline to defeat the Androids, and Imperfect Cell. However they're met by Cell in his perfect form. With the help of Towa, Cell was given a power-boost and absorbed Android 17 & 18 to achieve his perfect form. Luckily, with his new found power, Zero made quick work out of Cell, thus, restoring history.

Future Trunks thanks Android Zero for helping him, and asks, "who are you?" Android Zero says, "you'll know in time." before being returned to the Time Nest.

Back at the Time Nest, Zero receives another "thank you" from Trunks. They then ponder on who the stranger was that helped Zero go to the time change. Zero tells Chronoa what the stranger said to him. The surprised Kai wonders what it means. She walks away mumbling to herself, "it can't be...he shouldn't be able to enter into this world..."

Trunks brings up Zero's transformation. He said, "it almost looked like you went Super Saiyan." Zero admitted he wasn't sure what it was, nor did her know he was able to do it. He just reached deep within himself and pulled out the energy. Trunks thinks for a minute before exclaiming, "wait, don't you have a small amount of Saiyan DNA in your body? Perhaps you did go Super Saiyan, or at least in some form." Zero, being a master of mimicry, had studied the technique very closely, so it could be possible. Before he could think too intently on it, Trunks grabbed his arm and told him it was time to go train like a Super Saiyan.

Majin Buu Saga XV
After two months of training, another corruption is detected. This time, it's a battle between Goku and Majin Buu, when Goku first reveals his Super Saiyan 3 transformation. Goku is winning the fight, but not before Majin Buu is enchanted with dark energy and splits into three. Android Zero is sent back in time to help Goku defeat the triple threat Majin Buu.

When Zero arrives, he's met face to face with the time breaker, Mira, with Towa not far behind. Mira tells Zero that he's done sparring with the time patroller and will no longer be suppressing his energy. Zero returns the favor by entering his 'super' transformation. Mira and Zero were now on completely equal power levels, and only the more skilled fighter would prevail.

This was truly an equal match. The two continued to trade blow for blow. One false move from either party and it would mean certain death...and that's exactly what happened to Mira. Zero noticed an opening and delivered a powerful blow to Mira's rib cage, followed up by a lightning fast ki blast sending the demon flying upwards. Zero used rapid movement to appear directly in front of him, and cupped his hands together. During his training with Trunks, he learned a power ki wave. The Buster Cannon. Mira had no time to react before Android Zero disintegrated him. Android Zero looked back to see a visibly shaken, and angry Towa, before she teleported away in defeat.

Zero remembered Goku and the three Buu's, and flew as fast as he could to their location.

Goku was doing a decent job fending off the Buu's, but he warned his Super Saiyan 3 was wearing off. Android Zero jumped right into action and helped defeat the triplets. Goku returns to his normal state. But it seems that Majin Buu was not fully defeated. In-fact he returns as five smaller Buu's. Goku bows out leaving it to Android Zero to defeat the quintuplets.

During the fight, it seemed like whenever Zero would destroy one of the Buu's, it would just regenerate, and come back again. Although he was stronger than the five Buu's, his stamina was not infinite. The fight raged on for a half hour before Trunks chimed in and told Zero to say, "if he waits on destroying the Earth for just two days, he'll encounter an even stronger opponent." This peaks Buu's interest. "Stronger than Buu?" He said. Trunks told Zero to assure him that, that was true. Buu stopped to think for a second before agreeing. Then said, "Until strong guy comes, play with Buu!" but Zero had already returned to the Time Nest.

Back at the Time Nest, Android Zero is met with congratulations for killing Mira, and finally returning everything back to normal. However, Trunks stops talking mid sentence and points to Zeros hand. "What's that?" Android Zero's hand was glowing with a pink, and sinister energy. Chronoa comes running over and says, "give your hand to me, now!" She holds out her hands and sucks the pink energy into an energy sphere she created. She examines it for a second before quickly tossing it into the air and having it explode. Trunks asks, "what was that?" The Kai replies, "remember I told you there was a villain who tried to seize control of the Time Nest? It's him..." Tokitoki let out an alerting screech and signals to the top of the Time Vault. Standing atop the building was the staff wielding stranger who helped Zero return to the change in time. "Demon God Demigra" Chronoa said sternly, "I knew it was you." Demigra smugly tells them he only helped Android Zero so he could help him return to the Time Nest. He then demands that Chronoa hand over Tokitoki. He floats to the ground and raises his staff, but before he could do anything, Trunks rushes in and cuts through him with his sword. It appears that Demigra was only a mirage, and say's "we shall meet soon" before completely vanishing.

Chronoa says to herself, "so he was just creating an illusion of himself through his magic. He must still be stuck in the crack of time." Trunks asks what that is, and she says, "it is an enclosed space that is separated from the dimension of time. Demigra is supposedly imprisoned there." She walks away talking to herself trying to figure out how all of this came to be. The Time Patrollers have no other choice but to wait, and see what will happen next.

It was another two months before Demigra struck again. This time, the scroll showed Piccolo killing Trunks and Goten, then a disturbing vision of Super Buu destroying the Earth. Chronoa says that he's distorting history so he can bore a hole through the crack of time. Zero said he's going in, and arrives at Kami's lookout, Age 774.

At Kami's Lookout, Demigra has taken control of Piccolo and forces him to attack Goten and Trunks. Android Zero tells the boys to hold out for as long as they can while he fights Demigra. Demigra admits he's impressed by Android Zero's skill, but tells him defeating his mirage won't free Piccolo from his control. Zero lands the final blow on the mirage and flies over to help the struggling Saiyan boys defeat the villainous Piccolo.

After being knocked out, Piccolo awakens very confused, asking, "what, happened?" But before they could explain, Super Buu jumps over the side of Kami's Lookout. Piccolo too weak to fight tells the boys to fuse, immediately. Android Zero jumps ahead and fights with the pink being. Trunks and Goten successfully do the fusion dance to become Gotenks and joins in the battle. Buu is obviously overwhelmed, and uses instant transmission to flee from the fight.

Piccolo (after taking some time to rest) and Android Zero track down Super Buu to continue the fight. Buu is still no match for Zero and with the added power of Piccolo is beaten to the verge of death. Gohan, in his Ultimate form, flies into the battle only to realize he's not needed. Buu for the first time looks afraid. He mumbles to himself "no fun." Suddenly, Buu's eyes turn red and he jumps up. He's shrouded in a purple aura and turns into his original form, 'Kid Buu'.

Gohan is now needed in this battle, all three warriors fight off against the enhanced Buu, but even with their combined strength they're no match for the child sized creature. Buu grows bored of this fight and jumps backwards, and forms a massive 'planet burst' just like the scroll had foretold. Zero knows how this will end, and with no way of defeating Buu, locates two powerful energy levels and uses instant transmission.

Zero ends up on the Sacred World of the Kai. The two power levels he sensed her that of Vegeta and Goku...also, Mr. Satan was there. However, Kid Buu shows up not 2 seconds after the time warrior and engages in battle. Zero in his Super state and both Saiyans using their second transformation can't compare to the dark energy infused Kid Buu. Vegeta suddenly says he has a plan, and tells Dende, Kibito Kai, and Old Kai to travel to New Namek where they can summon Porunga, the Namekian Dragon. While all three continue to fight Buu, Vegeta barks orders to have them wish for the restoration of Earth and the resurrection of everyone killed since the morning of the 25th World Martial Arts Tournament, except for the most evil. Earth and it's inhabitants, including Vegeta, are revived by the Dragon Balls.

Vegeta then explains his plan to defeat Kid Buu: a Super Spirit Bomb made from the freely given energy of the people of Earth, transferred through Goku. He communicates to the entire planet via King Kai, asking the people of Earth to give their energy to power the attack, but only their friends and family believe him, and give their energy. Meanwhile, Android Zero is defeated by Kid Buu. Vegeta, who just regained his life from Porunga, attempts to hold off Kid Buu again so that the Spirit Bomb can be completed. Goku asks the people of Earth to help but only a few people Goku helped in the past actually give up their energy. Things look hopeless until Mr. Satan proceeds to tell the people to give up their energy so that he can defeat Kid Buu.

The people of Earth comply, and the Spirit Bomb is finished. Goku throws the Spirit Bomb, but is tired. Kid Buu is able to stop the Spirit Bomb and push it towards Goku. Android Zero appears alongside Goku and makes the spirit bomb move back towards Buu. Goku and Zero look at each other and smile. Goku turns Super Saiyan using the last bit of his energy to push the bomb into Buu; evaporating him.

After the battle Mr. Satan is jumping for joy and congratulates the exhausted Saiyans on a job well done, he turns around saying, "you did pretty well too" only to discover that nobody is there.

Zero instead receives his congratulations back at the Time Nest. Trunks then asks Chronoa, "who in the world is this Demigra?" She reveals that he was an evil sorcerer she fought 75 million years ago. She said he calls himself the Demon God, and tried to take Tokitoki and seize control of the Time nest so he could create a world where he controlled history. She imprisoned him in the crack of time, but it seems over the 75 million years he'd been biding his time, and gathering his strength. Chronoa then realizes she revealed her age and starts berating trunks. Android Zero, starts to feel lightheaded, and collapses in exhaustion.

God of Destruction Beerus Saga XV
For three months everything was quiet. Android Zero visited Trunks at the Time Nest who also voiced his concerns on the lull. Trunks asks Zero to go visit the Time Vault with him, but still, there were no corrupted scrolls. Speaking too soon, Trunks says, "maybe Demigra gave up?" A laugh is heard, and Demigra's Mirage is floating above them. The Demon God claims he'll never give up. Trunks replies, "there's no one else strong enough to be a threat to us!" Demigra laughs and say's, "do you really think so?" before vanishing.

Chronoa let's out a horrified shriek. She tells the Time Patrollers that Demigra is attempting to corrupt the time period in which, Beerus, 'The God of Destruction' goes to Earth. Both Trunks and Android Zero have no idea who Beerus is and don't understand The Supreme Kai of Time's nervousness. She says that, "if he were to turn against us, he'll destroy everything. All of history." They both understand the gravity of the situation and Zero goes back to Age 778.

Whis and Beerus are at Bulma's 38th birthday party celebration. Whis informs Beerus that there is supposed to be some delicious custard pudding and that Majin Buu is currently eating some. Beerus politely asks Buu for one, but Buu refuses, stating he will eat them all himself. Beerus cannot believe Buu will not share when he has so many, but Buu shouts back at him saying they are all his and proceeds to lick them all. Beerus struggles with Buu over the pudding until Vegeta quickly flies in, not wanting to upset the God of Destruction, and takes one of the puddings and gives it to Beerus. Android Zero has been quietly watching incognito from afar waiting for something to happen. Beerus is about to take a bite of the delicious pudding when a peculiar curve-ball, from Trunks and Goten playing, knocks it out of his hands. This greatly upsets Beerus and the Z Fighters have to step in, in an attempt to neutralize the threat. Majin Buu, Piccolo, Mystic Gohan, and Super Saiyan Gotenks are easily defeated by Beerus. Even Super Saiyan 2 Vegeta is no match.

As Beerus is about to finish off, Vegeta, Bulma, fed up with her party being ruined, walks up and scolds him for that by slapping him in the face. The God of Destruction is unaffected by this and slaps Bulma back, knocking her out. Seeing his wife being beaten, Vegeta explodes in a fit of rage. He powers up and attacks Beerus head on. Watching the battle from the Vault of Time, Future Trunks exclaims in amazement that Vegeta's power has finally surpassed that of Goku. Vegeta's anger gives him incredible strength, but as soon as his rampage is over, Beerus is left unharmed and proceeds to lightly tap Vegeta on the forehead, rendering him unconscious. Android Zero is still watching in the distance, Future Trunks explains that this is how history is suppose to be going, and to keep an eye out for Demigra.

Goku then arrives and pleads with Beerus to allow him to attempt to reach the Super Saiyan God form. Beerus agrees, and Goku decides to use the Dragon Balls in order to ask Shenron how to reach the form. The dragon says that a Super Saiyan God once appeared on Planet Vegeta to stop the evil Saiyans, but he failed because of the form's time limit. Beerus steps forward and asks the dragon the method of becoming a Super Saiyan God. Shenron then reveals that they need the light of five righteous Saiyans to infuse their power into another Saiyan for him to turn Super Saiyan God. Gohan, Goten, Trunks, and Vegeta hover above the ground, holding hands with Goku, and begin pouring their Super Saiyan power into him. Before long, Goku begins emitting an enormous power level. Everyone else then drops out of their Super Saiyan forms as their energy is completely transferred over to Goku, who is left with an amazing sparking aura. Krillin states that Goku has surely become a god now, but Piccolo responds by claiming that he has done nothing more than just gather up everyone's energy. Beerus agrees, noting that a god's energy is not expressed in battle power, and Goku realizes that he will still be no match for Beerus.

Whis then proceeds to remind them of what Shenron actually said, the power of five Saiyans must be infused into another. In other words, a total of six pure-hearted Saiyans is required. They struggle to think up where they can find another pure-hearted Saiyan, and Bulma remembers that Vegeta has a younger brother living off on some distant planet. Vegeta states he does not know his brother's whereabouts, and therefore, would not be of any help. Growing impatient, Beerus decides that he and Whis should depart, but Videl steps forward and says that there is another Saiyan, or at least that there will be. Dende then explains that Videl is pregnant, a fact she wanted to keep a secret to surprise Gohan later, but he is still ecstatic at hearing the wonderful news. Everyone is overjoyed and begins celebrating, but Beerus interrupts them and questions whether Goku is going to ascend to Super Saiyan God or not. The ritual is attempted again, this time, with the addition of Videl who carries a Saiyan-Human hybrid inside her. The six of them gather together and grab hands. This time, a blue light starts to emit from everyone and engulfs Goku, who begins to rise into the air. A bright blue light erupts from Goku, bursting into an intense aura that quickly dissipates, and Goku descends back down to the ground, apparently having finally become a Super Saiyan God.

Goku and Beerus stand facing each other, staring down one another. Goku gradually begins glowing, slowly emitting a fiery red aura, and then launches toward Beerus. The two start fighting with power incomprehensible to Android Zero. Still he must attempt to follow the battle. Beerus and Goku's battle is then pushed into a subterranean cavern. For a second it looked as though Beeru's eyes glowed red. Trunks said he saw the same thing. Still, Zero was only to sit back and watch. The two seem to be fighting even more viciously now. Suddenly Goku's red aura disappears and he reverts to his normal state. But the two continue their bout as if nothing changed. Goku then flies straight up, exiting the atmosphere, with Beerus giving chase. The two continue their fight until Goku admits that Beerus is too strong for him. Right before passing out, and being caught by Whis.

Beerus closes his eyes, only to open them again. This time they were glowing red and a purple aura started to surround him. He conjures up a massive Sphere of Destruction, and yell's, "time to destroy Earth!" Demigra appears behind the God and say's, "look, even Beers has his weaknesses. Now he is my puppet." Future Trunks chimes in telepathically essentially saying, "we're doomed!" Beerus goes to throw the energy sphere, but turns towards Demigra and chucks it at him. Demigra dodges, and is in shock. Beerus reveals that he knew he was there the whole time, and that trying to control him was blasphemous. Beerus lifts his index finger and destroys Demigra's mirage without effort.

Android Zero returns to the Time Nest, but with the added company of Whis & Beerus. Beerus say's he hasn't been to the Time Nest in a very long time, and starts to ask about Demingra. Chronoa informs him of the Demon God, and he say's that he'll be the one to destroy him. Chronoa, as politely as she can muster, tells Beerus that he can't fight him, for it would destroy the current dimension of time they're in. He is apathetic to the comment, and simply say's, "I know, I'm the God of destruction." Trunks and Chronoa plead with the god to let them handle Demigra, but Beerus rejects this and say's, "No. He tried to use me. It's unforgivable. Besides, can you even defeat Demigra?" Whis chimes in and says, "all things considered, why not try testing them?" Beerus, loving a good challenge agrees to Whis's suggestion, but also says that Whis must fight as well, since it was his idea. Chronoa interjects again saying they can't fight in the Time Nest. Beerus calls her selfish, but agrees to take the fight elsewhere.

Whis tells them to hold on, and they all shoot into the sky traveling at the speed of light. Android Zero and Trunks are taken to a rocky terrain on an alien world where they begin to test their strength against the God of Destruction, and his teacher. The two time warriors are hardly a match for the deities. Beerus mocks them both for being unable to even land a hit. The fight ends with Whis and Beerus simultaneously knocking out the Time Patrollers with a single hit.

The two wake back up at the Time Nest. Beerus say's he's, "going to take a nap before destroying Demigra. If anything happens during that time, so be it." Whis gives a winks before warping back to their planet. Chronoa informs Zero & Trunks that Beerus sleeps for years at a time. She also explained that while the two were out cold, Whis convinced Beerus to let them handle Demigra. He said he saw great potential in both the fighters, and could possibly be worthy adversaries in the future. Beerus obviously agreed to this citing that he could sense it too, even if they were incredibly weak at the moment. Chronoa then tells Trunks & Zero to get some rest, because, "we need to find, and destroy Demigra."

Demon God Demigra Saga
Four months later at the Time Nest, Trunks & Zero were training when all of a sudden, Chronoa goes white. She say's, "He finally escaped. Demigra is back from the Crack of Time" and that there is another corruption. She tells Zero he needs to go to Age 778, where Chronoa was sensing a very evil ki in West City on Earth, and tells Trunks to watch over Tokitoki. Trunks asks what she will do, and she replies with, "I have a plan. Now, go!"

Android Zero arrives in West City, but nothing could prepare him for what he would see next. His heart skipped a beat as he looked into the eyes of a revived Frieza, Cell & Buu. They all had that evil purple aura, but something was different. Their bodies were a bleak, purplish color, and under their glowing red eyes they had gained two black lines that ran down their cheeks. Zero could feel they were much more powerful now. Every move he made had to be precise. Zero could sense that Frieza was the weakest, and nowhere near his power level, so he instantly fires a powerful Galick Gun, eliminating him. Cell launches towards Zero and lands a blow to his stomach, knocking the wind out of the android. In the same breath, Buu grabs Zero and throws him into the air. Before Zero could react to his much stronger opponent, a purple beam was fired out of Buu's finger tip. Just as it's about to make impact with Zero, it's slapped out of the way, by none other than Goku. Goku say's he was wished into the future by The Supreme Kai of Time, and she filled him in on everything. Goku goes Super Saiyan, and tells Zero to take care of Cell, and that he'll handle Majin Buu.

Goku having the advantage over Buu and Zero having the advantage over Cell made the fight relatively easy. With only a few buildings being damaged, they sent the villains back to hell. This battle wasn't over yet though, Super Saiyan 3 Gotenks, Mystic Gohan, and Super Saiyan 2 Vegeta under the control of Demigras mind control fly onto the scene, and begin attacking. Goku and Android Zero had to be careful, they couldn't kill their opponents like they just did, they had to beat them out of being controlled. Goku shouts that he can handle Gohan & Gotenks, he just needs Vegeta to stay off of him. Android Zero complies and the brawl begins.

Even though Android Zero could feel he had a higher power level, Vegeta was one of the most skilled fighters he ever faced. One false move and the Saiyan Prince would have the upper hand. Meanwhile, Goku was easily handling Gohan and Gotenks. Zero had never felt a power like his before, he couldn't even comprehend his original mission of killing him. Before he knew it, Goku appeared behind Vegeta and with one chop to the neck, he knocked the Saiyan out cold. It seems that Gohan and Gotenks had already gone through that same process. Goku jokingly says to Zero, "sorry for interfering with your fight, but I think we're kind of on a time schedule here." Zero, looking stunned, agreed. Goku then say's, "Demigra used the Namekian Dragon Balls to revive Frieza, Cell & Buu. I need to go make everything right with that. I'm gonna leave Demigra to you. Don't worry, I'll catch up to you soon."

Back at Toki Toki City, the massive hourglass in the heart of the city started to crack, then explodes, with Demigra emerging from the debris. The demon spotted Tokitoki flying and captures the divine bird in a sphere of dark energy. After consuming the sphere, Demigra gains the power of a God. Android Zero arrives back in Toki Toki City and see's the destruction, with Demigra floating in the sky. He flies up to the Demon God where he propositions the Android to join him, telling him he can live like a god. When Zero refuses, Demigra say's, "that's too bad. It seems your friends do my bidding now."

Zero senses an immense power behind him, and it's none other than his friend/partner Trunks, under the control of Demigra. Trunks immediately engages Android Zero in battle. Demigra watches with extreme pleasure as Trunks and Zero fight each other. With Trunk's new power boost, he is overpowering Zero. Zero starts to gain the upper hand, with Trunks managing to grumble out, "keep hitting me." Demigra is surprised by this and shouts, "What? He's trying to escape my mind control?" Capitalizing on the situation, Android Zero unleashes a brutal combination of kicks and punches, knocking out Trunks, and relieving him of his mind control.

Demigra suddenly gets an idea and starts to put Android Zero under his control. Luckily, Trunks fires a ki blast with the last of his strength at the demon, knocking him out of concentration, and allowing Chronoa to quickly stop his mind control process on Zero. Demigra finally just say's, "Fine. If it's a fight you want, then it's a fight you'll get! You shall now see the power of the Demon God!" Demigra starts to fly towards Zero but is stopped in his tracks by Goku, who transported in front of him. Goku begins fighting with Demigra.

During the battle, Demigra becomes frustrated, wondering why his magic won't work on Goku. Goku replies with, "I don't know, maybe it's because I became a Super Saiyan God once, a god like you." Demigra is visually flustered by this point, and out of nowhere vanishes. Goku quickly tells everyone to grab onto him since he can sense divine energy, and he uses instant transmission to find Demigra. They're transported inside the Time Storage Vault where Demigra is threatening to destroy the vault. Chronoa say's, "are you insane? If you destroy the Time Vault, everything will disappear forever! It means you'll die as well!" Demigra replies with, "You fool, you think I don't know that? After everything is destroyed I'll make a new history. My history!" Chronoa asks, "What? What do you mean by that?" Before she can get an answer, Goku goes Super Saiyan 3 and flies towards Demigra, with Super Android Zero following. Demigra unleashes hundreds of Seasoning Arrows. Zero is dodging them as best as he can, but one strikes him through his chest and pins him to the ground. Caught off guard by this Goku is struck in the shoulder and falls to the ground as well. Both warriors are trapped in a prison of magic, unable to do anything to stop the Demon God. Android Zero was dying. The last thing he heard before losing consciousness was the cry of Tokitoki...

Android Zero slowly opens his eyes. He awakens in an unfamiliar place. Everything is white, and he wonders if this is Other World? He stands up and looks around. On the ground there is a time scroll. Curious, he opens it. The scroll shows the events of him being killed by Demigra. A time scroll means that he can go back in time and stop this from happening. Maybe there was hope. He utilizes the time scroll and goes back to the moment his past self, and Goku, were pinned to the ground. Demigra see's this and creates a large orb of dark energy, and escapes through a wormhole he created. Android Zero destroys the arrows pinning himself and Goku to the floor. Goku leaps up and grabs the dark energy ball, preventing it from making impact.

Android Zero can see that his past self is still dying. Chronoa yells that, "He only has minutes to live. In your present state you're no match for Demigra, but you two can combine bodies now and become even stronger." Both Android Zero's are surprised by this, but somehow know it's possible to do. They both link hands, and the dying Android Zero transfers his entire being into the future Android Zero. A blinding light envelopes the Androids, and when it dissipates they are one being. Android Zero was now in his perfect form, 'Perfect Android Zero' He looked more mature, and his hair went down to his upper back. He looked taller, and his clothes were slightly different. The most notable difference though was his power. Chronoa tells him that he was now stronger than Demigra.

Goku yells, "You need to hurry and follow Demigra! I can't hold this for too much longer" Chronoa adds that, "the wormhole is closing. Go!" Perfect Android Zero flies through the wormhole before it closes, and on the other side was the Crack of Time. This was where Demigra was imprisoned for over 75 million years. Zero see's Demigra in the distance. He yells, "What are you? What the hell are you!?" Zero calmly replies that, "it's over Demigra. I'm going to kill you now." The Demon God say's, "Fine. I won't hold back then!" He clutches his staff and transforms into a giant, and horrible looking blue monster. Since Zero was not a god, he couldn't tell if this transformation made him more powerful than himself. Once he started fighting with the beast though, he soon found out that Demigra was much stronger than him. Zero's only advantage was that he was much faster, and used this as best he could to land blows.

Whilst putting combinations into his back, Demigra's tail smacked him away, leaving the perfect android open for attack. The monster teleports backwards and launches a Boiling Ball at his exposed opponent. Luckily, Android Zero teleported away himself, thanks to the help of Goku who had now joined the battle. Zero and Goku are now both attacking the monster, but it seems to only be a slight increase. They needed to figure out a plan. Goku starts to communicate with Zero. He said, "this guy is strong, but I think if we use a combined attack we could defeat him." Zero agrees, and tells Goku to, "Teleport away from the fight, and to follow his lead." Goku teleports away and Zero tells him to, "close his eyes" Zero then teleports away and starts taunting Demigra to look at him. When the beast focuses his gaze on Zero, he uses Solar Flare to temporally bind the Demon. In the distance, Demigra can hear the words, "ka-me-ha..." bellowing from both Android Zero and Goku. He starts to rush towards his enemies using his ultimate attack 'Boiling Fist' His body is wrapped in a Nova Strike-like aura whilst charging his fist with energy. He's quickly approaching Zero and Goku when they let out the final, "-ha!" to their Combined Kamehameha. This stops Demigra in his tracks and there is now a massive struggle of power. The Saiyan, and Bio-Android put the last bit of their energy into the blast, and overpower the Demon God, finally killing him.

The powerful blast caused the Crack of Time to start collapsing. Android Zero could see a sphere of dark energy floating where Demigra was killed, and knew it was the captured Tokitoki. He rushed over and grabbed it, then Goku and Zero teleported back to the Time Nest.

With the heroes victorious and relieved that the struggle is over, Trunks propositions Android Zero. He said "well, your mission here is done. You fulfilled my wish, but, I was wondering if you'd like to continue being my partner in protecting the flow of time?" Zero say's "My life has meaning now, and I can't see myself doing anything else. Of course I'll continue to help in protecting the flow of time."

Then, in typical Goku fashion, he challenges Android Zero to a sparring match, noting that his power is incredible and wants to see it first hand. Android Zero agrees and gets in his fighting stance until Chronoa frantically stops them. "Wait! Don't do that here! If you break the Time Vault, everything we just went through will be for nothing!" Goku replies with a nervous laugh, "oh, yeah. Oops!" and the group all starts laughing.

A couple months later, Trunks, Chronoa, Goku and Tokitoki observe Android Zero as they test out 4 new Time Patrol candidates, however, Zero defeats them effortlessly, causing Trunks to yell at him for overdoing it. Beerus and Whis are seen floating above the restored Toki Toki City also watching on. Tokitoki flies up and perches on Whis' staff. They comment on Demigra's defeat and Android Zero's strength who Beerus hopes will become stronger. Goku tells them he should probably be getting back to his own timeline now, but if they ever need his help again, he'll be there. Chronoa makes him promise to come and visit, to which he agrees.

Meanwhile, back in Age 774, Towa recovers the surviving core of Mira and says they have failed but will return to take their revenge on those that stood in their way.

Legendary Super Saiyan Saga
Everything was as it should be in Toki Toki City. That was until Trunks said he felt a dark ki, and asked Zero to come to the Time Vault with him. Sure enough, one of the scrolls showed that history was about to become distorted. Chronoa explains that a wormhole is causing the distortion. Supreme Kai of Time then relates the wormhole with Demigra, the real causer of the mess in the whole time history. Android Zero is then sent to Age 737 to help Goku's father, Bardock fight with hundreds of Frieza's soldiers controlled under Demigra's Dark Magic. This task was easy enough, but a bit time consuming. When only around 100 soldiers were left, Bardock demands that Frieza reveal himself.

This is where the distortion had occurred. Frieza wasn't supposed to fight Bardock, he was only suppose to blow up Planet Vegeta. Frieza, exits his ship and is also under the control of Demigra's magic. Android Zero figured he just needed to rough Frieza up enough for him to retreat and use his Supernova attack to destroy the planet. So that's exactly what he did.

Frieza launches the massive energy sphere towards Planet Vegeta with Bardock getting in the way of the blast...or at least that's what was suppose to happen. Instead, Bardock was sucked into a wormhole before the Death Ball could kill him. Back at the Time Nest, Trunks and Chronoa make note of what happened and conclude that they need to follow the wormhole to find Bardock. The only problem was that Trunks said he, "didn't feel anything suspicious about the scroll". Chronoa said, "that since Demigra isn't controlling it directly, he might not sense anything coming from it." Then adds that he will need to manually check it out. Trunks is caught off guard by this and groans, "I have to check each and every one of these scrolls?! You mean, all of them?!" Chronoa walks away laughing and says, "good luck!" Zero graciously says that he'll help him narrow it down.

Hours later, they find the corrupted scroll. They don't know what the corruption is yet, but Trunks asks that Zero go back in time and check it out.

Android Zero is warped back to Age 774, where the Legendary Super Saiyan, Broly is about to attack a young Trunks, Goten, and Videl. To add onto Broly's already incredible strength, it seems he is also under the control of dark energy. Future Trunks is very alarmed by this, and questions where Bardock is. In the meantime, Android Zero rushes in to fight this legendary warrior, only to incapacitate the behemoth Saiyan in one hit. Not long after, Gohan shows up to see Broly trying to lift his body up, but before we could do so, the weakened Saiyan was swallowed up by another wormhole.

Back at the Time Nest, the Time Patrollers struggle to come up with an explanation for what is going on. Chronoa suggests that the wormhole could have placed them in the same era at least. The only problem was finding it.

A few more hours later and the corruption had been detected. Broly was about to fight with Bardock on the dying Planet Namek. Android Zero is sent back and see's Broly about to land a devastating blow on Goku's father. Zero shoots towards the 9 foot Saiyan and is about to hit him when they all teleport back to Earth. Zero asks what the hell that was, and Trunks replies with, "it was the Dragon Balls. Everyone on Namek was wished to Earth." Not letting this deter him, Android Zero finishes what he started and knocks out Broly. Out of nowhere, Vegeta flies in, no-doubt sensing a massive power level. He does not recognize Bardock, but Bardock recognizes him as the Prince of Saiyans. While the two Saiyans stared at each other, Vegeta's eyes rolled back into his head and Trunks: Xeno stood behind him. Zero seeing what his partner was doing knocked Bardock out as well. Trunks tells Android Zero to leave returning Bardock and Broly to their proper timelines up to him, while leaving Vegeta to recover on his own as he originates from that period, and that he'll meet him back at the Time Nest.

Baby Saga XV
A few weeks later, reports of another wormhole have been detected. Trunks said the distortion was happening in a timeline where Kid Goku had to face off against a Machine Mutant named 'Baby'. He warned that Baby was a more formidable foe than Buu, and to be careful.

Android Zero arrived in Age 789 where he saw Trunks and Pan...only Trunks wasn't acting normal. He was about to kill Pan! A flying kick from Zero incapacitated the enraged Trunks. Pan runs over to Android Zero and thanks him for saving her. Zero asked, "why was he attacking you" to which she replied, "He's under the control of Baby." Before Zero could ask anymore questions, A Golden Great Ape fell from the sky onto the battlefield. Pan exclaimed that, that was Baby! Zero told her to get away from here, which she begrudgingly agreed to.

His foe was massive and powerful, but nowhere near Perfect Android Zero's strength. In that moment, Zero realized that he must be one of the most powerful beings in the universe. During his pontificating Goku flies in next to him, only he was in a form he'd never seen before. He looked half-ape. Trunks communicates that, "this is Goku as a Super Saiyan 4, one of the most powerful transformations ever. All you have to do now is defeat Baby and everything should go back to normal." Zero lands a vicious uppercut on the golden ape, and allows Goku to finish him off.

As Baby twitched on the ground in defeat, a massive wormhole appeared above him and carried him off to another timeline, just like what happened with Bardock and Broly.

With nothing more to do, Zero returns home. Trunks tells him that he'll need to manually look for the scroll again, but he was getting the hang of it and didn't need any help. He said, "I'll contact you when I'm done."

Super 17 Saga XV
Trunks said while looking for where Baby went, he found another scroll. This is when a portal from Hell to Earth opened and all the villains from the past escaped.

When Zero arrived in that era, an undead army of Frieza's Soldiers were waiting for him. He wondered if any of these men were people he killed while fighting with Bardock. Either way, he had to send them all back to Hell. After a time consuming one sided battle, he had rid the solider plagued area of all enemies. But this was far from over.

Zero found himself surrounded by the Neo-Ginyu Force. Which was the Ginyu force, with an enhanced Nappa substituting for Captain Ginyu. After the posing, the Ginyu's circled around Zero. Not having time for this, Zero unleashed a lethal explosive wave, killing them all instantly.

In the distance he could hear a laugh, he looked up to see his brother, Android 17. Trunks informs him that this wasn't his brother. This was a version of his brother that was created in Hell. He's the reason why the portal between the two worlds opened up to each other. "According to regular history, your brother, 17 and Hell Fighter 17 are suppose to merge and become 'Super 17' just like what you did to become Perfect Android Zero." This wasn't good, with the power boost that Zero received after his fusion, that means his brother would experience something similar.

Reading the situation, Hell Fighter 17 could see that in his current state he was no match for Android Zero, and jetted away. Zero could easily catch up to 17, but he had to allow history to unfold as it should. Eventually he is lead to the location of his brother, Android 17, where he merges with Hell Fighter 17 to become the much stronger Super 17.

Unable to sense Super 17's energy because he's a machine, Android Zero fires a powerful energy wave at his 'brother' When the smoke clears, 17 is standing with his arms out and some kind of energy barrier surrounding him. His muscles had expanded and there wasn't a scratch on him. Trunks said, "oh yeah, I forgot to tell you, your energy attacks won't work. He'll just absorb your power." Zero says, "that would have been nice to know. Oh well, I'll just handle this the old fashioned way." But before he could do so, a wormhole sucked up Super 17. "Damn it! Why does this keep happening?" Said Zero. "I'm coming back now."

Shadow Dragon Saga XV
A few days later, Trunks discovered another wormhole. He warned Android Zero about the Shadow Dragons. About how they were created from the negative energy by overusing the Dragon Balls, and how they were very strong.

Zero goes back to Age 790 to fight with one of the Shadow Dragons named Nuova Shenron. Trunks mentioned that Nuova had fought with honor, but under the control of dark magic was another mindless killing machine. Still he was no match for Perfect Android Zero, nor was his more sinister, twin brother, Eis Shenron.

The defeat of the two Shadow Dragons brought fourth Syn Shenron, who had just devoured the other 6 Negative Energy Dragon Balls to become Omega Shenron. Though this was the strongest enemy Zero had faced since Demigra, Zero was still on another level.

After Omega Shenron was easily defeated. Two wormholes appeared above the battlefield, spitting out Zero's brother, Super 17, and the massive Golden Great Ape, Baby. This made Zero a little nervous, these were three of the most powerful beings in the universe. Luckily, backup arrived in the form of Super Saiyan 4 Vegeta & Goku, who then fused together to become Super Saiyan 4 Gogeta. Zero told Gogeta to take care of Baby, he'll handle 17 & Shenron.

To start off the fight, Zero fired a ki blast at Shenron as a distraction to close the distance on Super 17, who he couldn't use energy attacks on. Using his superior speed, Zero suddenly appeared in front of 17, and stuck his hand though his brothers chest. 17 couldn't believe what he was seeing, all he could do was hopelessly stare at Android Zero, who then said, "try absorbing this" as he fired a ki blast from inside the stomach of 17, exploding him. Omega Shenron looked on in dismay as Zero was aiming his index, and middle finger at him with his thumb sticking up to look like a gun. Zero simply said, "bang" as he lowered his thumb, sending out a single, yellow energy beam from his fingers tips. The beam then split into hundreds of separate smaller beams of energy, and shot through the Shadow Dragon, killing him instantly. Zero said, "I call that the 'Hollow-point Galick beam"

As Omega Shenron hit the ground, Baby soon followed. Gogeta had done his part and defeated the Machine Mutant. After the battle Goku & Vegeta thanked Zero for the help, and he returned back to the Time Nest.

When Zero returned, Trunk informed him that no other anomalies had been detected, and that he thinks they finally have restored time back to it's normal state. In celebration of this, Chronoa said that she'll make the Time Patrollers dinner to which they both rejoice. When The Supreme Kai of Time walked away however, Trunks said, "prepare for your toughest quest yet. Supreme Kai of Times cooking is...well it's more destructive than any enemy out there." Zero looks at him in disappointment, but breaks the silence with a good laugh.

Power
Android Zero is a bio-android, which means when he trains, he can grow stronger. From his conception, he has been training. He was created as a test to see if something like Cell was even possible, so his potential is immense.

He's a master of the mimicry technique. If he witnesses a type of attack or technique, he can almost certainly recreate it. This is due to his brain being filled with simulations, combat footage, and the DNA of multiple races before being born.

Before he was wished into the future by Trunks, Android Zero was about as strong as his brother, Android 17.

During his fight with an enhanced Android 17 and 18, Android Zero achieved his transformation into 'Super Android Zero' This gave him a huge power advantage over his brother and sister. In the moment of his transformation, his power level increased to around Evil Buu.

Android Zero fused with a dying, past version of himself to become 'Perfect Android Zero' giving him a massive power increase. At the time of the fusion, he was a little weaker than the base form of Goku Black.

Perfect Android Zero is considered to be one of the most powerful fighters in Universe 7.

 * Ki Blast - The most basic form of energy wave.


 * Full Power Energy Wave - A powerful energy wave technique.


 * Solar Flare – The user spreads and places their fingers on their foreheads, discharging a blinding flash of light.


 * Kamehameha - Charged Energy Blast created by Master Roshi.

 * Explosive Wave - A technique where the user bursts out ki from all over their body in order to repel the opponents around them.


 * Super Explosive Wave - A much more powerful version of the Explosive Wave technique.


 * Exploding Wave - A powerful attack in which the user manipulates their ki to disrupt the planet's geomagnetic field. With a swift upwards motion of the hand, the user can create a massive atomic explosion that has the potential to cause an almost endless crater in the desired area.


 * Photon Bomber - The user raises his right hand as he curls his fingers and charges a white energy sphere that is thrown.


 * Continuous Energy Bullet - A combination of many energy waves, much more powerful than the average ki blasts, and fired at a very rapid rate.


 * Galick Gun - A powerful, fuchsia-colored ki beam that emanates from the hands and body. It is capable of destroying large planets if enough power is put into it.


 * Special Beam Cannon - Two thin energy beams are unleashed from the fingers. One remains straight while the other coils around the straight beam. The resulting beam is quite powerful, drilling through most targets, and exploding on the ones it can't.


 * Death Ball - A spark of energy lights on the index finger. Once enough energy is gathered, this spark may grow to the size of a small moon and is thrown towards the target. Typically, this attack is used to destroy planets or as a last-ditch effort to kill an opponent.


 * Buster Cannon - Charging two blue energy spheres in the users hands. They combine them together in front of them to fire the energy wave at the opponent, inflicting a great amount of damage.


 * Shine Shot - The user prepares a ball of fire in their hands and throws it, tossing the fireball at the opponent to severely burn them or worse.


 * Final Flash - The Final Flash is formed by drawing both hands back while gathering ki. Then, the user place bottom of their palms together, forming a sphere of energy that then discharges a massive golden beam of energy with electric ki streaming around it.

Speed and Movement Techniques
 * Hollow-point Galick Beam - The user points with their index, and middle finger with their thumb pointing up, to look like a gun, once the thumb is lowered, a single beam shoots out of the finger tips, eventually splitting into hundreds of smaller beams.
 * Flight – The user uses their ki to give them the ability to levitate.


 * Afterimage Technique - An ability to move so swiftly that an image of the user is left behind.


 * Afterimage Strike - A technique in which the user distracts his/her opponent with several afterimages.


 * Rapid Movement - Moving at great speed, which creates the illusion of teleportation.

 * Instant Transmission – Also called Instantaneous Transmission the user places their index and middle finger on their forehead, sensing a location that they teleport to.
 * Ki Sense – The ability to sense others power levels.

Martial Art Techniques

 * Kiai - It is a technique where the user affects the air currents around him with ki to produce powerful shockwaves in order to strike the opponent.

Power Up techniques
 * Mimicry - The coveted ability to copy another fighter's technique after seeing it used only once.
 * Kaio-ken (x20) - A technique that multiplies the user's ki for a "heart beat" - thus increasing their power and speed and enabling them to inflict serious damage to opponents who are considerably stronger than them. However, the downside of the Kaio-ken is that it takes a heavy toll on the user's body.

Super Android Zero - Android Zero has a small amount of Saiyan DNA in him. Combined with focusing his ki (similar to Kaio-ken) and his master ability of mimicry, he was able to achieve a similar transformation of a Super Saiyan. In this form his hair stands straight up, and gains an orange tint. His pupils disappear, and his muscles become more pronounced. He also has a pale yellow aura surrounding him.

Perfect Android Zero - Android Zero fused with a dying, past version of himself to become 'Perfect Android Zero' giving him a massive power increase. After the fusion, he looked more mature, and his hair went down to his upper back. He looked taller, and his clothes were slightly different. Any kind of blemish that was originally on him had vanished. In his perfect form, his body heals at incredible rates. He also became immune to disease and poisons because his cells fight them off instantly. If he focuses hard enough, he can regenerate body parts. This is also due to the small amount of Namekian DNA he has.

Captain Ginyu's Body - Ginyu tries to swap bodies with Goku, but Zero flies into the path of the beam thinking it's a regular energy blast.
