From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Bojack (ボージャック, Bōjakku) leads the Galaxy Soldiers.
His name is derived from the Japanese word bōjakubujin, which means arrogance or audacity. This is dubbed as Bojack for the English release of Bojack Unbound, while Bujin is used for the name of another character in the film.
Bojack is depicted as having a husky 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 Full 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.
Dragon Ball Z: Bojack Unbound
Bojack appeared in Dragon Ball Z: Bojack Unbound. He was a ruthless alien who would stop at nothing to conquer the universe. Bojack could only be impeded by being locked inside of a star by the Kais of the universe, where he would remain for thousands of years. However, with King Kai's death following the destruction of his planet during the Cell Games, the link holding Bojack trapped is shattered, leaving him unbound to make his escape (hence the name of the movie, "Bojack Unbound"). Tracking the energy coming from the Cell Games to Earth, Bojack travels to the planet accompanied by his henchmen, Bido, Bujin, Kogu, and Zangya. In Dragon Ball Z: Budokai Tenkaichi 3, he and his comrades are dubbed the Galaxy Soldiers.
Infiltrating a World Martial Arts Tournament funded by X.S. Cash for his son's birthday, Bojack seeks to eliminate every single fighter on Earth in order to be rid of any obstacles in the way of universal conquest. While his minions frequent the arenas, Bojack waits calmly in a ruined city where the final challenge of the tournament is meant to take place. Eventually, his minions gather the bodies of Future Trunks, Kuririn, Yamucha, and Tenshinhan. Gohan, the only fighter still standing, lashes out at Bojack but is interrupted by his minions whilst Bojack watches on.
Before Bojack can finish him off using a Full Power Energy Ball, Piccolo appears and deflects the attack with his Special Beam Cannon. Piccolo then engages Bojack himself in a fight where he is quickly defeated by a Grand Smasher. Before landing a final blow with an energy attack, Trunks intervenes and fires a barrage of energy blasts, to which Bojack merely erects a blue barrier around himself. After Vegeta arrives on the battlefield, he battles Bojack as a Super Saiyan. After defeating Vegeta, Bojack decides to assume his transformation into Full Power Bojack (フル パワー ボージャック, Furu Pawā Bōjakku). After taking out Trunks, Bojack and his minions attack Gohan and manage to best him. Bojack then wraps his arms around the wounded Gohan, preparing to squeeze him to death. In an instant, however, Bojack receives a punch in the face by the deceased Son Goku, who has somehow "broken the rules" and returned to Earth for a single minute.
Gohan emerges as a Super Saiyan 2, effortlessly wiping out both Bujin and Bido. Becoming desperate despite insisting that Gohan cannot stop him, Bojack sacrifices his fearful, remaining underling, Zangya, when he pushes her towards Gohan and fires an energy sphere straight through her. Gohan evades this, prompting the delirious Bojack to attack head-on, only for Gohan to land a punch straight through the tyrant's stomach.
Certain of the high threat Gohan poses, Bojack launches his ultimate attack, the Galactic Buster, which Gohan counters with a Super Kamehameha. The two energies clash and result in an explosion. Both Gohan and Bojack rush through to attack each other in the flash of light, however, Gohan punches clean through the tyrant using his father's Penetrate! attack to stop him once and for all. Bojack instantly explodes as he yells out in pain.
