Subspace has pink horns curling around his head, framing a glowing crystal. He wears a grey gasmask, eyepatch, and black tank top, with a grey shoulder wrap featuring Greek-key patterns. Sadistic and loud, he often taunts enemies, especially Medkit. Once colleagues, a violent fallout left Medkit injured and Subspace dying from poison. He conducts unethical experiments and suffers from rotting teeth and face, losing his sense of taste.
