Independent assassin-for-hire, whose associations are commonly with those he is hired to kill, lackeys include Miss Locke, White Rabbit, Miss Coriander and Mister Chambers.
Arcade gave differing accounts of his past life, and as yet there is no evidence to substantiate any of those accounts. Apparently Arcade told falsehoods about his past to mislead and confuse his opponents for his own amusement.
One of Arcade's accounts stated that he was the spoiled son of a millionaire living in Beverley Hills, California, and killed his own father to acquire his vast sums of money on his 21th birthday, possibly also because he had treated him of being worthless[1]. In killing his father, Arcade discovered that he had a talent and liking for murder. He therefore became an assassin, but was soon bored with killing by ordinary means, and used his great wealth to construct hidden complexes of high-tech death traps designed in the manner of an amusement park.[2]
Arcade killed victims by trapping them within his "Murderworld" for whomever would pay the millions he charged. To Arcade, the game itself was more important than the expense or even the winning. Arcade was also contracted to kill various super heroes, from common foes like Spider-Man and the X-Men, to other targets like Puck and Northstar of Alpha Flight, and Ghost Rider, but these attempts always resulted in failure. Occasionally, Arcade held personal grudges against heroes, trying to kill them for free, such as Captain Britain.
Arcade killed his long-time assistant Miss Locke and mutilated his own face during a plot to frame Wolverine in a complex "Jack the Ripper"-like series of murders. His plot was defeated by Wolverine, Gambit, and his former ally Mastermind (Martinique Jason), the daughter of Mastermind, who left Arcade in a state of delusion.
At some point, Arcade recovered, and returned to his usual modus operandi, capturing heroes such as Spider-Man and the Black Cat but escaping capture.
Arcade and White Rabbit attempted to kill Wolverine and the Black Cat but failed[3]. He also appeared to have a relationship with White Rabbit but they broke up[4].
Recently, he created a new Murderworld, where he battled the New Avengers, but failed.
Arcade had a relation with Miss Locke but prefers to killed her[1].

Throwing a party at his estate for his birthday, Arcade realized it was made fun of him by the super-villains community, and was wounded by Miss Coriander, his new assistant, after having ask her to try to kill him. He then give his Murder Island to her and flee to his bar, The Hole, in Central Bagalia, where he was burgled by one of the villains who had made fun of him, Constrictor. Defeating him with a trap, and possibly killing him. Arcade decided to create a new project, inspired by children's novels.
Helped by Miss Coriander, he created a new Murderworld in Antartica, and was provided with powers from cybernetics, magic stuff, Stark tech and gamma radiation[1].
He kidnapped sixteen teenage superheroes: the Avengers Academy's Hazmat, Mettle, X-23, Reptil (Humberto Lopez) and Juston Seyfert, the Runaways' Nico Minoru and Chase Stein, Kid Briton, Ryker, Anachronism, Nara, Apex, Bloodstone, Red Raven, Cammi and Darkhawk. He put them on a deserted island, his new Murderworld, telling them that they would be trapped there for a month and would have to kill each other to survive. This, of course, caused the heroes to attack him. However, Arcade displayed an incredible new range of superpowers to defeat them. He told them to chose the 'weak link' of the group, and that he'd kill them first. Hazmat continued attacking him, so Arcade chose her for the group. Mettle offered himself in her place, and Arcade complied, blowing him to pieces before leaving[5].
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. He calls his entire complex of specially designed traps Murderworld.
