Colossor is a character in He-Man and the Masters of the Universe.
Using the energy gathered by his Collector, Skeletor brought Colossor to life and ordered it to capture Castle Grayskull. It reached the castle while Teela and Battle Cat were standing guard, but He-Man soon arrived with reinforcements. Ram Man couldn't put a dent in the metal colossus, so Man-At-Arms tied its feet together while Orko distracted it with a flash of light. Stratos and He-Man then pushed Colossor off-balance, knocking it to the ground. Colossor reached for Castle Grayskull even after its great fall, but He-Man destroyed it with a mighty punch in the foot and used the Power Sword to burst free from the rubble that buried him as the colossus crumbled.
