Mongul is the brutal ruler of the planet-sized weapon of mass destruction called Warworld. Using Warworld to conquer planets across the cosmos, the tyrant enslaves the inhabitants and forces the strongest among them to serve in his horde army or suffer an uncertain fate in gladiator-style games for his amusement. Mongul's immense size, rock-like body, and rapid regeneration make him nearly invincible. And his super-strength, speed, and agility make him almost unstoppable!
