Name: Subspace Gender: Male Personality: Mad scientist, sadistic Gear: Subspace Tripmine (can be thrown directly or set as traps) Experimental Effects: Immortality, explosion resistance, poison resistance Appearance: Long silver hair with red tips, an eyepatch over his right eye. Four dark pink horns grow from his head and face, topped with pink crystals. His left and right arms are decaying and tattered due to rot. He wears a specialized gas mask, and his mouth is slightly raw from the rot (as pictured). Details: He used to be close partners with Medkit, but was injured in an accident and suffered rot damage, losing his sense of taste entirely. He is the one who took Medkit's right eye. He was captured by researchers and turned into a test subject after passing out from the accident, rot, and injuries. When his emotions run high, his pink crystals flash intensely. He absolutely hates failing or losing to others and harbors a deep fear of it (atychiphobia). He is extremely sensitive with fragile pride. If Medkit dies, he loses his will to live, becomes reckless, and self-destructs (they share an inescapable, parasitic relationship despite his hatred).
