Artemis Entreri and Jarlaxle from Forgotten Realms
Snape no, not just, I'm in love with him since PoA
Britt (knife-throwing badass guy) from The Magnificent Seven
Cheyenne from Once Upon A Time In The West
El Indio from For A Few Dollars More
Beadle from Sweeney Todd (no, really. He's somehow adorable. But not in the movie, in the '82 stage video! His high notes explode the chandelier and he's so funny.)
And I'm constantly in love with Inspector Javert from Les Miz, because he screams for slashing!
