The Incredible Hulk is possibly one of the scariest superheroes out there. All superheroes are meant to be “out of this world” and awe-inspiring, but I think most people will agree with I say The Hulk takes this to the next level. He is the result of an industrial accident, which is scary enough in it’s own right. Plus, when mild-mannered Bruce Banner is angered, he goes completely out-of-control and transforms into a destructive monster that he cannot control and has no memories of.
