I've always liked Worf, even when I was little. (dad's always been a Trekkie, and i've inherited it, so i've been watching this for as long as I can remember.) I associated with being hot-blooded and stubborn.
I've been thinking of writing a scene in a Gargoyles fanfic where Coldfire sees STTNG and thinks Worf is the most attractive character on the show. (He doesn't have wings or a tail, but those are minor flaws....)
