Ah, interesting! There's quite a lot of older X-Men stuff I haven't read yet. I know it's very silly, but the old stuff with Hank seems kind of tainted with how he's acting now. He was heroic then but now he's an amoral asshole.
Yeah, I agree Immonen did a very good cat Hank, and yes I thought 'horse' when I saw that image of Hank I posted.
(BTW, are my images posting okay? They look weird in preview for me. It's been a while since I posted in a forum like this and my formatting was never very good)
