Show: Buffy the Vampire Slayer
Before she made her more mainstream debut in 2000's Bring It On, Dushku was already a beloved fanboy antihero. As Faith, the sardonic Slayer teetering the line between good and evil, Dushku deliciously compensated for the reckless abandon Buffy lacked and would periodically reinvigorate the show with its much needed edginess when Buffy would inadvertently make even her most nefarious adversaries fall in love with her.
