NO. 21: ALI LARTER
as Tracy Strauss/Niki Sanders in Heroes (2006-present)
WHO IS SHE? Niki and Tracy are two of three identical blondes. Niki, now deceased, was a former Internet porn star and mother of a kid who talks to machines. Tracy is a high-powered political operative helping newly minted senator Nathan Petrelli (Adrian Pasdar) find his footing.
SKILLS Niki had a second personality, Jessica, who was incredibly strong and brutal. Tracy can freeze objects — and people — with her touch.
MALE ADMIRER Niki is survived by her tech-savant son, Micah (Noah Gray-Cabey), while Tracy has ''spent time'' with Governor Malden (Bruce Boxleitner) before setting her sights on Nathan.
CAN'T GET ENOUGH? Larter went down the tough-babe road once before, in Jay and Silent Bob Strike Back (2001).
