Red Hulk/Headscratchers


 * Why is Red Hulk an Avenger? He destroyed S.H.I.E.L.D.'s helicarrier, beat up every superhero that got in his way, and conspired with a Supervillain group to take over the world. He had a Heel Face Turn, but I don't think that qualify him for being one of "Earth's Mightiest Heroes"
 * Because the inmates are running the asylum at the moment.
 * Is  really a villain in the first place? He's always seemed more like a Well-Intentioned Extremist from my point of view.
 * He's a Hulk soldier without the anger issues, he's a great choice. Besides, he was originally just given missions by Cap in order to make up for all the stuff he did before. After proving to them time and time again that he was geniunely a good guy who would help them save the world, they let him join. I think Fear Itself was the first time he worked on the Avengers team, and that was only because of the chaos going on in NY.
