Juggernaut

Juggernaut (Cain Marko) is a fictional character appearing in American comic books published by Marvel Comics.  Cain Marko is a regular human who was empowered by a gem belonging to the deity Cyttorak, becoming a literal human juggernaut. He possesses superhuman strength and durability, and is virtually immune to most physical attacks; his helmet also protects him from mental attacks. In some reinterpretations, Marko is a mutant who was born with this powers, while in others they simply come from his costume. Although not a mutant, Juggernaut has been featured as a prominent member of the Brotherhood of Mutants. He is also the stepbrother of Professor X.
