Cain Marko is one of the X-Men’s first villains. His hatred for his step-brother Charles Xavier (Professor X) led him to try and kill Xavier’s students and team. He should be one of the first antagonists to fight the X-Men in the MCU. It would be a great fight with a deeper meaning. This would also lead to Cain fighting other Marvel Studios heroes.
Juggernaut has battled heroes like Hulk, Spider-Man, Thor, and given each of them a run for their money. Once he appears with the mutants in the MCU, it could lead to him being in more projects. Not just movies. He’s the right kind of antagonist for a show because Cain isn’t really a bad guy. He can start as a crook and become a hero. Eventually, maybe even an X-Man.
Actor: Roman Reigns
9. Brotherhood of Evil Mutants
When Magneto started the Brotherhood, they didn’t consider themselves evil. He believed he was fighting for a heroic cause. When Mystique was in charge, she took the word evil and embraced it. Mystique led Destiny, Blob, Avalanche, and Pyro. This team may not look intimidating, but the right cast and creative team and they could be. Plus, it doesn’t have to be this roster. Since this isn’t Marvel Comics, Sabretooth, Omega Red, and other mutants could be the team in the MCU.
Mystique actress: Jodie Comer
Destiny actress: Marilee Talkington
