Arcade affects a manner of dress and speech that makes him appear to be a comedic character. This is part of his overall theme, which extends into his preferred method of murder, an underground funhouse of colorful deathtraps, usually decked out in cheery colors and disguised as an amusement park, which he has dubbed “Murderworld”.
Arcade became a freelance assassin, traveling across the world, killing people in rather mundane fashions, and amassing even more wealth than he already had. Discovering an aptitude for technology, Arcade designed and built his first Murderworld, a subterranean evil lair disguised as an 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, he would tailor Murderworld to exploit the specific weaknesses of his targets and then watch as they are killed by a variety of colorful deathtraps strewn throughout the facility. However, one of his “gimmicks” is that he always deliberately leaves each target a small chance of survival.
