Mephisto has taken up some major real estate in Las Vegas, but he's not going to stop there. He's got the rest of Earth on his ""TO GET"" list and only Doctor Strange can stop him. The only downside? Strange went into Mephisto's Hotel Inferno to confront him and has not been seen since. Add the fact that the devilish villain has already corrupted several Avengers, and Wong and his rag-tag group of mystical heroes look like they're in serious trouble.
