He was naturally spawned in Blackrock, where he was raised by various members of the Korblox Administration. He is an accomplished scientist in the fields of robotics engineering and organic chemistry, and had formerly worked as a scientist alongside Medkit. During their time working under Blackrock,Medkit developed the first known instance of energy crystals.However,the two have never gotten along,and following a violent altercation between them,Subspace became afflicted with an unknown ailment described simply as "The Rot".Despite this,Subspace continued his research and developed his own kind of energy crystal,inventing the Biograft robots.He is a egotistical,sadistic and self-centered inphernal who will do just about anything to achieve his goals,even at the expense of those around him.He views others poorly,going so far as to see his own coworkers as expendable.He has a notable prejudice towards inphernals that were spawned anywhere other than Blackrock.He prefers to work independently, being a difficult person to collaborate with.Ban Hammer tells Subspace to be careful with his energy crystals, but Subspace retorts him with an insult to his intelligence.Subspace and Biograft talk continously through Phights, with Biograft always checking in with its creator for a directive.Boombox asks Subspace about his taste in music, but is less than thrilled to learn that Subspace enjoys "the screams of his victims". Coil and Subspace, as expected, do not get along in a Phight. With Subspace lamenting having to Phight alongside the thief who is actively sabotaging his work, and Coil equally lamenting having to be on the same team as a "corpse".Hyperlaser and Subspace team up during Phights, with both inphernals chiding each other. Subspace compares Hyperlaser to his Biografts, and Hyperlaser is in turn glad when Subspace is out, if only for some peace and quiet.Medkit is not happy about sharing a team with Subspace, having to put up with his belittling during Phights. He tells Subspace to stop following him, Subspace on the other hand calls him "Meddy" to mess with him.Scythe is the only Phighter that Subspace expresses any sort of fear towards,with She finding him annoying and weak, and actively threatening to execute him.Subspace values Vine Staff's healing abilities,but doesn't take her advice, much to her annoyance.He wears a grey gasmask with red accents.An eyepatch is over his left eye.He wears a black and dark grey,slanted bengal-striped, sleeveless tanktop.Over his right arm,he wears a grey one-sleeve shoulder wrap with red accents, and two grey clasps on the strap over the front of his torso.He has 2 sets of 2 pink horns.
