X-Men Files: Arcade

Arcade is a hitman who is often hired to take out irksome heroes. While he is normally rather successful, Arcade rarely fares well against true superheroes. Despite his prowess in killing people, Arcade refuses to kill them in typical ways, preferring instead to build giant death traps called Murderworlds to kill them, enjoying the game itself more than the actual murder. Due to his inability to kill anyone of consequence, and his exuberant mannerisms, Arcade's reputation among the villain community has declined rapidly, and even young superheroes such as Hazmat have cited him as "the worst bad guy ever."

Powers
Arcade normally has no superpowers of his own, but gained a multitude of energy-based powers via a nanomachine-enhanced suit that only functioned within his new Murderworld in Antarctica.

His insanity seemingly grants him some level of comic awareness, allowing him (for example) to grasp and eat the little angel and demon on Deadpool's shoulders.

Abilities
Genius Intelligence: Although he has no superhuman powers, Arcade has a genius level I.Q. and a natural aptitude for mechanics, architecture and applied technology. A brilliant and self-taught designer, Arcade applies his talents to the construction of mobile amusement park-like deathtraps, which he calls "Murderworlds".
