Man oh man, Kitty. Depending on the medium, she can come off as bland and mary-sue-ish at a glance, but when written well (any of the cartoons for example (even that really old one with the Australian Wolverine), or her early appearances) she's totally awesome! In my top ten for sure. This is great, love it! Wish we could've seen her in the original animated series at least a couple times. Or they could've used her instead of Jubilee.
I find it amusing and annoying that nerds got on the nerves of the woman she was named after (or so I've read). Can't blame her, but Kitty brings so much joy to people as a character, how can one not be happy about that?
