Then... probably Storm. When she doesn't have a mohawk.
Hmm, I feel the opposite. But then, she had a mohawk when I first started reading X-Men (ca. 1981?), so it was weird for me when she grew her hair out!
Anyway, mine by far is Havok. He's the only one I really follow. Well, him and Polaris.
Alex has had so much crap thrown at him since the '60s that you never know if he's going to be a "good guy" or a "bad guy", just like most real people. I was way into X-Factor in the mid-'90s when Alex took over the team, and what a cool team it was.
It's weird because I'm the older, brown-haired brother while my younger brother is blonde, and he's the one who's always been in my shadow, and yet...Havok is just so much more fun to read than Cyclops most of the time!
And his girlfriend is Polaris! 'Nuff said?
Hope he's doing ok out there in Space Prison...
