One of the coolest bad guys that I have seen in a superhero movie in the last few years was Ultron. He was as powerful as the superheroes that he battled. If The Avengers were able to kill Ultron, what would they do with him?
Every time I watch The Avengers, I think to myself that Hawkeye really doesn’t belong there with the others. His only superpower seems to be shooting an arrow and having good vision. Black Widow is questionable as well but she likes tight clothing and can throw a punch so I am willing to let her slide for now.
