Some people say that getting bitten by something radioactive could give anybody superpowers, but to their disappointment that stuff only exists in movies, and other forms of fiction. What actually happens is much more painful, as the radiation inside the human body begins to alter it at a rapid speed every moment at a time.
When people get bitten by a radioactive creature, they aren't going to develop superpowers. Instead, they will become mutants, or myths depending on what kind of radiation the creatures stand by. The scientists of our period have researched two different kinds of radiation. If a creature is orange radiated, they will turn humans into mutants, but if the creatures are green radiated, they will become myth creatures that have almost no legs, and sometimes more legs than they thing they should have.
