Goku black (ranma½ story)

Zamasu was a Kai from Universe 10, but was being trained by Gowasu to become the next Kaioshin. After a fight with Goku, Zamasu became obsessed with Goku, and with his growing hatred of mortals, he killed his master Gowasu and became a Kaioshin, also taking the Time Ring. Using the Super Dragon Balls, Zamasu switched bodies with Goku, and after that killed him, along with his family. After that, Zamasu assumed the identity of "Son Goku". Zamasu then used the Time Ring to travel through different timelines, until he observed Trunks and Shin's fight against Dabura. Seeing Shin die, Zamasu is happy to find a timeline where Beerus is dead. Zamasu then travels to Universe 10, and, killing the Gowasu of that timeline, allies himself with the version of himself from that timeline. They then used the Super Dragon Balls to make Future Zamasu immortal, killed all the gods of all the universes, and then put into practice the "Zero Mortal Plan", attacking and decimating the population of several planets, until they arrived on Earth, where Bulma gave him the nickname "Goku Black".

Black's physical appearance is similar to Goku's, but with thinner eyes, like Bardock's. He wears a gray gi, with a black long-sleeved shirt underneath, and a red belt. He also wears a green Potara earring in his left ear.

He's not romantic at all, or at least he doesn't seem to be, he has a certain taste for tea, he'll always end up fighting with you at one time or another, but he'll still protect you, no matter how much it goes against his ideas.
