Luke Perry as Pike in Buffy the Vampire Slayer

Really, what better way to spark a relationship than saving your love interest from a vampire? That’s exactly how things heat up between Valley girl cheerleader Buffy and high school bad boy Pike. (She saves him, of course.) In the role, Perry worked the sensitive rebel shtick he perfected as teen dream Dylan McKay on Beverly Hills, 90210 (though the actor was actually in his mid-20s when the series began).
