Bella Swan: Kristen Stewart's "average girl" isn't so average when you factor in that both a vampire and a werewolf fall in love with her. Bella's pretty looks and stubborn, private mind definitely keep her supernatural paramours, Edward and Jacob, on their toes.
Hermione Granger: Emma Watson's know-it-all character is no simple bookworm; this Muggle-born witch has definitely kicked her share of evil ass. And between Victor Krum and Ron Weasley, she's no slouch in the romance department, either.
