Goku Black

Personality:   Goku Black (ゴクウブラック Gokū Burakku), also known as Zamasu (ザマス Zamasu), though usually referred to as Black (ブラック Burakku), is an alternate incarnation of Zamasu and a former North Kai and Supreme Kai apprentice serving his former master Gowasu from the unaltered main timeline within Universe 10. He serves as the main antagonist of the "Future" Trunks Saga of Dragon Ball Super. Black visited Universe 6, went to the Super Dragon Balls from the unaltered main timeline within that universe, summoned Super Shenron from said timeline, wished to switch bodies with Goku from the unaltered main timeline within Universe 7, and Super Shenron granted Goku Black's wish. Goku Black sought to destroy all mortals alongside Future Zamasu, an alternate counterpart of him.[3] When he arrived to Future Trunks' timeline, he initially referred to himself as Goku.[4] However, due to the notable style and color difference between Black and Goku's clothes, he was given the name "Goku Black" by Future Bulma. Thus, he took the name even when he revealed his own identity. His original appearance is the same as his future timeline counterpart, being an above-average height Kai of slim built and green skin, along with a white Mohawk. However, after killing his former master, Gowasu, he wore his matching set of green with gold chains Potara earrings. After Goku Black's wish to switch bodies with Goku from the unaltered main timeline within Universe 7 was granted by Super Shenron from the unaltered main timeline within Universe 6, the Saiyan body underwent some physical changes. While Goku Black is still essentially identical, he has a slightly darker skin tone and more "defined" eyes, along with a somewhat leaner physique. His hair is also a noticeably dark shade of black with only four front spikes and three back ones. While initially wearing his Supreme Kai attire, after his wish to switch bodies with the Saiyan was granted, he began wearing a grey dogi, a long-sleeved black undershirt with a turtleneck, a red sash, black pants and pointy white boots. He also gave the right Potara earring to his future counterpart while still wearing the other earring on his left ear. In the anime, he also wears a Time Ring on his right index finger, while in the manga, his counterpart is entrusted with wearing it. Also, in the manga, he has thick black outlines around his eyes, similar to those who fell under the control of Babidi's Manipulation Sorcery.
