Kolossus was a cyborg weapon built in the cold war by the Russians to fight the Americans in case they got too advanced in their weaponry
The upper half of colossus body looks like a skinned apish humanoid with exposed muscle, tree trunk thick arms, a sturdy sinuous neck and a giant head with a peanut shaped bright pink brain and broken teeth. The lower half its body is a pair of robotic legs. its upper body is cased in metallic armour with electrodes wired to the chest. The head has a metal mask with a visor housing two sparks mistaking for eyes( its real eyes are bloody and bulgy).
