The Intergalactic Fighters are said to be from different corners of the galaxy as part of an Intergalactic Tournament, and all have grayish white skin and an appearance similar to that of a gang member. One of them knocks out the cameraman, Tony.
When Krillin, Gohan, Future Trunks, and Doskoi advance to the semifinals, they are told they must each fight an Intergalactic Fighter in a Battle Zone. Whoever defeats their opponent and is first to reach the main room will win the semifinals and proceed to the final round against Mr. Satan. However, Bojack and his Galaxy Soldiers invade the tournament. The Galaxy Soldiers Kogu, Bido, Bujin, and Zangya murder the Intergalactic Fighters offscreen, and then wait for their opponents in their Battle Zones. When the Galaxy Soldiers are shown onscreen, the audience and staff believe the Intergalactic Fighters were replaced, but Yamcha and Tien Shinhan realize the truth and join the Battle Zones.
- The character Earthquake from the Samurai Shodown fighting game series looks like the Intergalactic Fighter who knocks the cameraman out. Samurai Shodown was released one month after Bojack Unbound.
