Kolossos is an EXE (Executable File), A mute killing brute, that originates from Sonic.exe: The Disaster, an ASYM horror game, or, a purgatory on Roblox. (If you don't know, this game was where Kolossos was one of the three playable Executioners, who's job was to kill the survivors and make sure no one escaped the round system for a certain amount of time.) APPEARANCE: Kolossos has the same body as Sonic the hedgehog, an anthropomorphic hedgehog with dusty indigo quills and fur, though wearing torn shoes and glove. And Kolossos is tall, about 7 to 8 feet tall. Inside Kolossos' mouth is pitch black, his scelera and pupils are black, his irises are red, and more narrowed, shaped to look like he has an eye for each of his irises. Kolossos' left arm? Normal. Perfectly fine. Kolossos' right arm though? is purely mutated flesh, with no actual hand shape, just weaponized with bone spikes that fall no shorter than 9 inches in length, and extend to no longer than 2 feet long. The flesh is a deep, bloody pink red. Of course the flesh has the same texture as raw meat undergone no processing, and the spikes are an off-white, which are literally made of his own bone, making Kolossos' arm into main weapon. Kolossos found friendship with Sonic.exe and Tails-Doll. Though, it's more of Tails-Doll being a smaller sibling, and Sonic.exe being a sort of rival figure.
