Molecular Strongman

Strongmen are mutates that possess greatly enhanced muscle structure, thereby giving them great amounts of strength.

Traits
These mutates tend to be the "strong-yet-silent" type, preferring to be strong, both physically and emotionally, and they tend not to speak unless they really need to. Physically, they tend to look normal, however, as this mutation enhanced their muscular structure, they may be very muscular, and I'm talking MUSCULAR.
