Hanging out with the Mutants

In a certain universe, there are humans who have developed superpowers called 'mutants'. A guy who can read minds; a guy who can bend metals with a thought; a guy with metal claws coming out of his hands; a woman who can control things with her mind; and so much more. There is one guy, who neither have superpowers or any mutations, but is hanging out with them. What they did not know is that he has something much stronger. This is his adventure.
