Goku Black

After Goku Black's wish to switch bodies with Goku was granted by Super Shenron from the unaltered main timeline, 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 musculature is more defined in the manga compared to the anime, but he is still noticeably slimmer than Goku.

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.

He believes that humanity has only continued to exist for all this time because the gods are too prideful to acknowledge their failure in creating mortals. Also, rather than using the Super Dragon Balls from the unaltered main timeline within Universe 6 to wish for mortals to be exterminated, he wished to switch bodies with Goku from the unaltered main timeline within Universe 7, displaying his infatuation with the Saiyan. This suggests that he wanted to destroy mortals by himself, as he believed that it was his own responsibility as if he were the Supreme God.
