Subspace is an 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 within his division in Korblox, with the reputation to match. Despite all this, Subspace is generally fond towards his robotic inventions, preferring to work with them over any living inphernal.
