7. Arcade
Arcade is a genius-level hitman who is also extremely flamboyant and charismaric, appearing at times to resemble a game-show host with his manner and mode of dress. His prime choice of slaughter is an underground maze of death-traps named Murderworld, which he has designed to be disguised as an amusement park. Arcade charges a fee of $1 million for anyone who wants a target assassinated in this park, tailoring it to the weaknesses of the victim, and then watching as they attempt (usually unsuccessfully) to evade the traps. Though quite a cinematic villain, Arcade is simply
too campy and theatrical for his own good, and whether facing off against screen iterations of Spider-Man, X-Men or Iron Man, it's difficult to see where there would be a place for such outrageous behaviour.
