General Pilaf
Pilaf is the main enemy in the first Dragon Ball chapter. He finds out about the Dragon Balls and wants to use them for his own power. He uses his two henchmen, Shuu and Mai to try and get the Dragon Balls of the DB gang, but they fail and are beaten up by Goku. Goku is Pilaf's most hated enemy. He destroys his castle in DB, and Pilaf doesn't re-appear until DBGT, when he finally collects the Dragon Balls, but wastes the wish by accidentally wishing Goku to be a kid again. He then runs away in frustration and is never seen again.
