Mystery Mouskatool

An extremely buff "person?" with (not literal) iron skin and even tougher (also not literal) iron fists. He was a one time hire by Tartarus as a Janitor but did not really seem to care about who he was punching. He threw Visor-Chan into Labrynthia and tossed Anthony aside like tissue paper with ease.
He kicked Frank in the ribs for knocking Daliala unconcious as he seemed to know her and wanted to ask a question. Moments later, he Grabbed Mysterious Gamer X and jumped into the void of the Grand Temple of Tartarus.
Once the battle between the army of Gaia and Tartarus was reaching a climax, both him and X made a reappearance to retrieve the Cubic Portculis because as X said "We are broke".
