Clipped from Wikipedia: Arcade first appeared in Super Spider-Man & Captain Britain Issue #248 (November 9, 1977), a Marvel UK black-and-white comic. This story was simultaneously colorized and released in the United States as Marvel Team-Up, Volume 1, Issue #65 (January 1978). Discovering an aptitude for technology, Arcade designed and built his first Murderworld, a subterranean evil lair disguised as a very deadly amusement park. From this base, and with the help of two mysterious assistants named Miss Locke and Mr. Chambers, he reemerged as the world's most expensive hitman. For the price of $1 million (actually a token sum, since Arcade doesn't need the money and, in any case, never turns a profit), he will tailor Murderworld to exploit the specific weaknesses of his target and then watch, with unconcealed glee, as they are killed by the variety of colorful deathtraps strewn throughout the facility.
Dork Note: Lamest hit man EVER! Arcade spends millions building an amusement park of death just to trap and kill someone...that's just CRAZY! Wouldn't it just be easier to shoot or blow them up? But he is really good at it, right? Umm, no. He has never successful killed any costume hero. So why would anyone hire this guy? The Evil-Dork never would! (by the way Evil-Dork is me in a parallel universe where I am a super-villain)
