I was actually never all that attracted to Strongbow until he got his facefur. It made him look older and I'm attracted to older men. Pre-facefur Strongbow just held no attraction for me.
However, I always thought his best episode was in Books 7-8. His quest for redemption was very touching. It also showed him interacting with Clearbrook. Before then he had mainly kept to his family. Having Clearbrook help him showed that he wasn't as anti-social as he would have us think.
So yeah, I don't find him all that good looking but I do find him an interesting and tender character.
He's also fun to torture in fanfiction. :twisted:
