Zachary David Alexander Efron (or [[FanNickname Zefron]], born October 18, 1987) is an American actor and singer whose first (and most famous) major role was as Troy in ''Film/HighSchoolMusical''. Since then, some think that [[SugarWiki/HeReallyCanAct he has branched into a more "serious" actor with better performances.]] He often plays the BigManOnCampus.

He dated [[RealLifeRelative HSM co-star]] Music/VanessaHudgens for five years. They split in late 2010; both attribute the breakup to simply growing up.

He may [[MemeticMutation also be]] [[Manga/DeathNote Kira]].
