From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
The Pilaf Gang (ピラフ 一味, Pirafu Ichimi) is a group that Pilaf leads.
Pilaf desired to take over the world using the Dragon Balls. His two most significant henchmen were Shuu and Mai. It was implied a couple of times early in the series that he had other minions as well, but they were unseen. One notable thing about Pilaf was that he had a disposable amount of resources. The original base for his forces was Castle Pilaf located in the Diablo Desert. When Son Goku turned into a Great Ape and destroyed it, he got a new base, Pilaf's Flying Fortress, which was later shot down by Colonel Silver's troops. One significant thing they later acquired were the Pilaf Machines, giant battle robots they used to fight against Goku, thus making them a bit more closer to Goku's strength in battle. Piccolo Daimao was released by Pilaf, which ultimately backfired when he took over and made his own forces. The Pilaf Gang returned to interrupt Goku and Son Chichi a couple of times on their quest for the Basho Fan.
