Super 18

Super 18 is the transformation of Hell Fighter 18 after absorbing Android 18 created by Dr. Gero and Dr. Myuu.

Biography
After the destruction of Super 17 at the hands of Goku, Dr. Gero and Dr. Myuu decided to once again join forces and create a counterpart for Android 18, Hell Fighter 18. The two master-minds built the Machine Mutant with the objective to locate and absorb Android 18 and bring about the death of Goku and the destruction of Earth.

When she located Android 18, she first asked her to let herself be absorbed, but Android 18 refused and was absorbed by force also bringing about the death of her husband Krillin and daughter Marron. Now having been transformed into her ultimate form she quickly located and challenged Goku. She battles and defeats all that stand in her way, such as Majuub, Trunks, Goten, and Vegeta. Goku transforms into Super Saiyan 4 and unleashes all his power on the Android. Goku, along with distracting fire from Piccolo manages to get behind her an unleash a x10 Kamehameha while her energy shield is down, thus destroying her.

Techniques and Special Abilities
Ultra Sensitivity – By concentrating his mind, Super 18 can sense the very changes in the air and sound, which allows him to detect even the stealthiest opponents, such as Goku using the Instant Transmission. This ability can be nullified with loud noises.

Ki Blast – The most basic form of energy wave.

Levitate – Like most characters in the series, Super 18 can fly in the air. However, like most Androids, he does not possess ki, so he flies by the means of a certain machine called Hikou in his body.

Android Barrier – Android 18's signature defense technique, which has been retained in this Super form. This is an Energy Shield that protects Super 18 from harm, and seems to be very resilient enough to withstand Goku's self destruction technique.

Absorption Barrier – Like Android 19 and Android 20, Super 18 has the ability to absorb energy into himself through a certain pose and add it to his own. This is a feature Dr. Myuu installed into Super 18. He has made this his own type of absorption ability by not only regaining energy by stealing it, but by adding it to his maximum power and making him stronger, with the added effect of his muscles continually engorging so long as he has energy to consistently absorb. Rather than absorb energy with the inlet devices on his hands (or rather, in his case, on his gloves) like the other two, he instead extends his arms and legs outward to somewhat resemble a star and raise an invisible field capable of absorbing what seems like anything as long as he holds that pose. The limit on how much energy can be absorbed (if there is one) is unknown, as he even absorbed Goku's 10x Kamehameha. However, this leaves him open for physical attacks, as he cannot counter while absorbing.

Thunder Eraser – An attack where he dashes towards his enemy with an open hand and fires a purple and black energy sphere at point blank range which then splits into several smaller, yellow energy waves.

Hell's Storm – In a manner similar to Android 16, Super 18 detaches one of his forearms, but instead of firing massive blasts from the cannon hidden in his arm like 16 does, Super 18 fires several hundred bullets in a Flash Bomb-esque fashion, albeit in a concentrated and narrow straight line.
