Bruce Banner's cousin Jennifer Walters receives a blood transfusion from her super green cousin, resulting in her gaining the ability to transform into a diluted version of the rage beast we all know and love from one of films he's appeared in. Naturally, since Banner becomes a savage beast thing that throws tanks around like kiwis, Walters just turns into a green-skinned Amazon woman with LLL cup boobs and thighs that could crack coconuts.
At first glance you might think it's obvious that She-Hulk was meant to be sexy and sexual; after all, she's a female comic book character, and traditionally female comic book characters have existed to give bustier designers in the fictional universes they inhabit something to do, but She-Hulk isn't your average Power Girl, busting down walls with her nipples and for some reason entering every room vagina first. She's still a big green rage monster. She has her personality and all, but she's big and green. That's weird, right?
I first discovered She-Hulk when I was about 12, and there was something curiously sexy about those big green thighs to me. Green was new and delightful. I wanted that. I wanted to plow that verdant field. Why? She was unique. I had never seen a green woman before (I hadn't seen that episode of Star Trek yet) and it was exciting in a whole new way. I wondered briefly if I was racist, but then quickly decided that since I wanted to shower with her, it was the opposite of racism, whatever that is. I was enlightened due to my desire to climb She-Hulk like a garden wall.
To this day She-Hulk is drawn in the same overtly sexy fashion as all female comic book characters -- the poor girl can't keep her clothes on, after all, what with the rippling boobs and power buttocks tearing through her business suits left and right, and there's no rhyme or reason to the attraction to her, but man, it's still there.
