I'm very fond of She-Hulk, I even think she has a great origin. I enjoyed the run by John Byrne and I know it was mostly tongue-in-cheek good girl art, but I enjoyed it. However, I am glad to see some changes made to her as a character and while some have not been pretty, they've added depth to what was once a barely 2-dimensional character that only served as a female version of Hulk not unlike Spider-Woman is to Spider-Man for Marvel's marketing purposes.
My one contention with Shulkie is that she has a lack of a rogue's gallery. The Incredible Hulk has plenty of enemies, even on the side of good, yet his cousin seems to be sorely lacking in this area.
The main two contenders who've been a thorn in She-Hulk's side have been Titania and Starfox. I know she's BATTLED plenty of characters, but have any really been declared enemies of She-Hulk?
Oh, I could throw in Madcap for sh*@ts and giggles, but I don't know if he really qualifies.
If I am missing someone, please fill me in. If you have any suggestions, that'd be even better!
