Endo

Endo is an "Ender Warrior" that escaped from the Galactic Patrol Prison and began to destroy the universe, using limitless power he gained from the space atmosphere. At his full power, Endo is capable of defeating a God of Destruction.

Bio
Around 57,000 years ago, a young Endo was used as a weapon to destroy planets, but was soon pursued and captured by the first Galacic Patrol. However, the Patrol was unable to kill Endo, so was forced to store him away using a contained black hole.

After being released by a breach of the Galactic Patrol's Villain Vault, Endo begins his rage upon the universe, starting with the elemination of the Galactic Patrol. Jaco was one of the only survivors of the extermination, allowing him to travel to Earth and warn Goku.

Endo is fuelled by his harsh upbringing and his time spent locked away in a black hole. He also gets his power from the molecules of space, converting them into raw energy for his body. As space has unlimited space particles, Endo draws limitless energy. The time-control of the black hole stopped Endo's body from absorbing the particles from inside, otherwise he could have emerged as the strongest being of all time.

Endo's Power
Endo can only get stronger from his time in space. After spending one full Earth day in space, Endo was able to get from the level of Frieza in the Namek Saga to the level of Super Saiyan 3 Goku. Retreating after a tough battle with Vegeta, Endo spends several more days in space, reappearing stronger than Super Saiyan Blue Vegeta.

Defeating Vegeta and then Goku. Endo decides to spare planet Earth due to the challenge Goku and Vegeta posed. However, he destroys all adjacent planets.

Goku and Vegeta decide to seek further training in order to stop Endo's growing threat. Meanwhile, Bulma decides to work on a device to stop Endo from collecting space particles. Piccolo, Gohan, Jaco, Goten and Trunks use the Super Dragon Radar to locate the Super Dragon Balls for a multi-resurrection.

To re-access Ultra Instinct, Goku asks Vegeta to launch a fatal attack directly at him.

Failing to access Ultra Instinct, Goku is sent to the otherworld and seeks immediate training with the Grand Kai, the same Kai who helped him to access Super Saiyan 3. In a non-mortal body, Goku was able to push Super Saiyan Blue further, ready for him to be resurrected with increased power. However, Goku taps into Ultra Instinct when paired against Hell Absorbed Kid Buu!
