Kolossos

He is much larger, taller, and bulkier than standard Sonic characters, functioning as a towering brute.He has dark navy or dark blue fur with triangular ears and traditional Sonic spines.His eyes are sunken and dark (or completely hollow pitch-black/void sockets) with small glowing red pupils or dots inside.He is a brutal, chaotic evil entity who takes malicious pleasure in causing pain, destruction, and mass suffering.  Rather than acting out of blind, mindless rage, he is described as cold and self-indulgent in his violence, treating the slaughter of survivors like a predatory hunt. He rarely speaks words, choosing instead to communicate through chilling, demonic laughs, growls, or grunts primarily while attacking prey. Creator OutLaik has noted that he is not strictly mute, but rather chooses not to talk. He stalks his targets with a heavy, hulking, and aggressive demeanor, functioning like an apex predator isolating the weak.
