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 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 has been a long time 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.

— Bojack commenting on Gohan's fight with his henchmen
Bojack is a ruthless Hera-jin who would stop at nothing to conquer the universe. He committed most of their genocidal tendencies in the Dormideous Sector and 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.
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, Krillin, Yamcha and Tien Shinhan. Gohan, the only fighter still standing, lashes 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, deflecting the attack with his Special Beam Cannon. Piccolo then engages Bojack himself, in a fight where he is quickly defeated with 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, Super Bojack. After taking out Trunks, Bojack and his minions attack Gohan and manage to beat him. Bojack then bear hugs the wounded Gohan, preparing to squeeze him to death, similar to what Cell did in the Cell Games, as his way of "thanking" Goku for his part in freeing him and his minions. In an instant however, Bojack receives a punch in the face by the deceased 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. Bojack then prepares to capitalize on Gohan's evasion of the earlier attack by charging an energy wave and then jumping and firing it at Gohan below. To his shock and irritation, he discovers that Gohan was not affected by the attack at all, 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 enter a beam struggle and result in an explosion through which both Gohan and Bojack rush through to attack each other, however one final punch into the flash of light ultimately kills Bojack.

Bojack makes his first playable appearance in a Dragon Ball video game spin-off in Dragon Ball Z: Super Butōden 2. In the Story Mode, he and Zangya try to get the Dragon Balls. They create evil clones of the Z Fighters in order to trick them, and they later spread the Destron Gas on Earth and use the Cell Juniors as henchmen. If the Z Fighters fail to defeat Bojack, Broly will appear and kill him, thus ending the Story Mode if the player has not complete certain tasks.
Bojack has since appeared in all three installments of the Budokai Tenkaichi series, all of which allow his transformation form to be played. In Dragon Ball Z: Budokai Tenkaichi, he has a part in a saga called "The Plan to Conquer Earth" in which he gets his revenge by killing Gohan. He and his comrades are dubbed the "Galaxy Soldiers" in Budokai Tenkaichi 3. Bojack is also a playable character in Dragon Ball: Raging Blast 2. He and his team appear in the Japanese only arcade game Dragon Ball Heroes.
