Michael Emerson is the son of Lucy Emerson (
Dianne Wiest) and the older brother to Sam (
Corey Haim). He is seen as being a relatively quiet teenager interested in fitness and motorcycles. He moves from his hometown of Phoenix, Arizona to Santa Carla, California after his mother's divorce. While there, Michael becomes infatuated with a girl named Star (
Jami Gertz), who appears to be in a relationship with
David Powers (
Kiefer Sutherland). David challenges Michael to a deadly motorcycle race, which Michael loses, and invites him back to their hangout. While at their hangout, David taunts Michael before eventually offering him wine, which was really David's blood, turning him into a half-vampire. David and his gang hang off of the underside of an elevated train before each individually falling off. Eventually, Michael loses his grip and falls, before waking up in his own bed with a new ear piercing. Michael's new status as a half-vampires eventually manifests itself when he begins reacting negatively to sunlight, constantly wearing sunglasses, and one night begins flying around the house involuntarily. He confides in his brother Sam to help him, as Sam had recently befriended self-proclaimed vampire hunters Edgar and Alan Frog (
Corey Feldman and
Jamison Newlander). Michael has another encounter with David where David attempts to persuade Michael into killing. Michael instead watches in horror and fear as David and his gang massacre a group of Surf Nazis. Michael returns home where he comes across Star, who reveals that she too is a half-vampire and Michael was intended to be her first victim, which would have turned her into a fully-fledged vampire. After this, Michael leads Sam, Edgar and Alan to David's lair, where they rescue Star and another half-vampire, Laddie (Chance Michael Corbitt), and end up successfully killing one vampire, Marko (
Alex Winter). The group barely escape with their lives and only do so because it is still daytime and the vampires cannot follow them into the sunlight. That evening, Michael, Sam, Edgar and Alan prepare to defend themselves, Star and Laddie inside the Emerson house from David and the other two remaining vampires, Paul and Dwayne (
Brooke McCarter and
Billy Wirth). This results in the deaths of the other two vampires, leading to a final confrontation between Michael and David, which ends with Michael impaling David on a set of deer antlers. After killing David, Michael and Star notice that their vampiric abilities are still present. It is then revealed that Max (
Edward Herrmann), a seemingly innocent video store owner who was romantically interested in Lucy, is the true head vampire who had David turn Michael in hopes of getting Lucy to become a mother to the vampires. Michael's grandfather (
Barnard Hughes) then stakes Max with his tractor, freeing Michael, Star and Laddie from their vampirism. ==Other appearances==
