Lol. I love Nightie because of his personality. I mean, the smile is awesome, and the fur is great, and tail etc, is cool and kinda hot. But I fell in love because of his personality.
Let's see, my favorite character in pretty much any huge fandom is usually odd looking: Spock, Data, Darth Maul, Professor Lupin, etc.
The guy I really think is hot is usually pretty normal looking: Chekov, Bones, Qui-Gon Jinn, Snape, and... dare I say it.... okay, WARREN when he doesn't have blue skin and metal wings.

Nightie was never my "he's super-hot" character. Nightie was my "I'd love to hang out with him" character.

RIP Kurt Wagner. You were the character who brought in me into comics, who introduced me and inspired me. Now your death has sent me away again. Wherever you are in the Marvel Universe, I hope its someplace pleasant.
