Years ago, I always watched X-Men: Evolution with my brother. I remember having the hots for Nightcrawler. His goofy accent always made me smile, and he was adorable both in his actual form and in his simulated human form. Since then, although I still adore Nightcrawler so, I've fallen hard for Wolverine. Mm-mm-mm, no explanation necessary. Iceman's pretty cute, too, and sweet to boot.
For some reason, I've never considered Cyclops anything but a bit of a joke. Judging by the answers, I guess I'm not the only one.
And the only animated bald guy I dig is Ramses from The Prince of Egypt.
