Arcade

Arcade is a devious Villain who turns the entire game into an elaborate deathtrap. He has 12 different Threat cards (unlike the normal 6) which he keeps in a shuffled deck. His BAMs keep adding Threat cards facedown in the Locations. Whenever a Hero enters a Location with a facedown Threat, it is revealed, with results that range from the annoying to the devastating, depending on the trap that was laid there, and the state of that Location. To add to the mayhem, Arcade is constantly flipping Threats back down, or shuffling them around. May the best mutant win!
