SHE-HULK: A female superhero with brains, brawn and a sense of humor, AND she's one of the most attractive females in the MU? Yeah, sign me up. I love that she is a character that is used to point out the absurd nature of comic book superheroes but is still firmly a person trying to do good with her powers. Love her as an AVENGER and in THE FF and her being a lawyer is just the cherry on top.
THE BLACK KNIGHT: I want to love Dane, but he seems like a "scrub" Avenger to me. He's in that Starfox, Stingray, Gilgamesh the forgotten one category of Avengers. Some seem to like his run of stories under Harras, and of that I will just say, "Let X-Men do X-Men".
NICK FURY: Great character. Both as an awesome James Bond styled male fantasy character with the knob turned up to 11, and as the man in the shadows government liason to the hero set. I can understand though feeling the need to turn the reigns over to a newer character.
