Some enemies of Chacha are Raaka (once a dacoit, but an immortal giant after drinking a magic potion made by Chakram Acharya), Gobar Singh (a dacoit), Dhamaka Singh, and his accomplice Paleeta and Ruldu.
Many a times Chacha Chaudhary has beaten Raaka (with the help of Sabu, of course) and once forced him to shave off his mustache as a result of some competition which was won by Chacha.
