Bojack

Bojack (ボージャック, Bōjakku) is the main antagonist of the 1993 film Dragon Ball Z: Bojack Unbound. He is the leader of the Galaxy Soldiers. His name is derived from the Japanese word bōjakubujin, which means "arrogance" or "audacity." This was dubbed as 'Bojack' for the English release of Bojack Unbound, while "Bujin" was used for the name of another character in the film.
Bojack and his crew were designed by Akira Toriyama, the original manga author, for Toei's theatrical production. Toriyama's designs can be seen in Daizenshuu 6.

Bojack is depicted as having a muscular build, and resembles something of a gypsy-pirate. His skin is colored teal, his long hair is orange and he has a long scar scaling his face. Bojack has a maximum-power transformation which renders his skin chartreuse, his hair red and his muscle mass increased over the top (a trait which numerous foes encountered in Dragon Ball possess). His outfit is also shredded by the transformation.

Bojack is shown to have a bloodthirsty personality, as he mentions upon revealing himself to Gohan that it was a long while since he "snapped someone's neck." He is also known to have little to no loyalty to his own comrades, as evidenced when he killed Zangya the moment she showed signs of fear, and due to her being in the way of Gohan. He is also shown to be quite arrogant, as he firmly believes that he can defeat Gohan, and is prone to getting very angry when it becomes apparent that he is having difficulty fighting against Gohan.
