Warning! Spoilers ahead for X-Men #13!The X-Men's villain turned superhero, Juggernaut, is among the Mutant heroes’ strongest, and Marvel just redefined how Juggernaut’s healing factor sets him apart from other fast-healers like Wolverine or Hulk. Juggernaut may no longer be an avatar of the god Cyttorak, but his recently illustrated healing factor shows he still holds god-like power, and it functions in a whole new way that makes the red powerhouse just as strong.
