The female version of the Hulk is never going to win any prizes when it comes to original naming strategy, but this is one case where we can say we're sure that the female version of the character is better than the male one. The male version of the Hulk character can be something of a liability. Bruce Banner doesn't have much control over when and where the Hulk appears, and when he does, he's just a concentrated green Goliath of rage. He generally fights for the good side, but he can easily do as much harm as he does good.
She-Hulk is the Hulk's cousin and has the whole 'being green and angry' thing under much more control. She stays green all of the time, and when she's not being called upon to save the world, she finds time to work as a lawyer. She also gets a proper costume, instead of shredding hundreds of dollars' worth of clothing every time she gets angry. She sounds like a happier, more stable person in general.
