5 Marvel Comics Villains Who Are Currently MIA
3. Arcade
Arcade hasn't been in a position as a major villain since 2014's Avengers Undercover. He's got a history of making the X-Men's life hell and his murderous theme park-based shenanigans are sorely missed. The concept of Arcade alone is pretty cool and the fact that someone is so enthusiastic about murder that they're willing to build a theme park around it is a testament to their dedication to mayhem.
The fun thing about Arcade, if you consider murder fun, is that due to his gimmick there's a lot of creative things writers can do to portray his sinister machinations. He was even deemed fun enough to have an entire section of the first Marvel Ultimate Alliance game dedicated to him and a carnival of his mischief.
It's slightly more plausible to have Arcade missing for a while as he's likely sourcing the money and materials, then building a new murderous landscape for his next victims. However, it's been far too long and it would be great to see smarter, younger heroes who are yet to test their wits against him, like Prodigy and Moon Girl, face down his terrible creations.
