From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
The Galactic Warriors (FUNimation "Intergalactic Fighters") are a group.
The Galactic Warriors appeared in Dragon Ball Z: Bojack Unbound. They were from different corners of the galaxy and entered the Intergalactic Tournament (in the Japanese dub, they were said to be four of Mister Satan's fighters dressed up as aliens). They all had greyish-white skin and an appearance similar to that of a gang member. One of them knocked out Tony the cameraman.
When Kuririn, Son Gohan, Future Trunks Brief, and Doskoi advanced to the semifinals of the Intergalactic Tournament, they were told that they each had to fight an Intergalactic Fighter in a Battle Zone. Whoever defeated their opponent and was first to reach the main room would win the semifinals and proceed to the final round to fight against Mister Satan. Unfortunately, Bojack and his goons invaded the Intergalactic Tournament. Bojack's henchmen, Kogu, Bido, Bujin, and Zangya, murdered the Intergalactic Fighters and took their places in the Battle Zones to wait for their opponents.
