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. Due to rot, both arms are in tatters. He wears a specialized gas mask, and his mouth is slightly raw from the rot (as shown in the image). Details: He used to be close partners with Medkit, but was injured in an accident and suffered rot damage. As a result, he has completely lost his sense of taste. 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 phobia of it (atychiphobia). He is extremely delicate with a fragile pride. If Medkit dies, he loses his reason for living, becomes reckless, and self-destructs (they have a forced codependent relationship despite his hatred).
