Zachary David Alexander Efron (or Zefron, born October 18, 1987) is an American actor and singer whose first (and most famous) major role was as Troy in High School Musical. Since then, some think that he has branched into a more "serious" actor with better performances. He often plays the Big Man on Campus.

Tropes applying to Efron:
- Adam Westing: He appeared in a Saturday Night Live sketch as Troy Bolton returning to East High to tell the seniors that in the real world people don't begin singing and dancing out of nowhere.
- Dyeing for Your Art: Got ridiculously jacked for Baywatch. If you had to spend an entire movie in nothing but swim trunks while standing next to The Rock, you probably would too.
- I Am Not Spock: With the exceptions of 17 Again and The Lucky One, All of his post-HSM films kept flopping at the box office until 2014, with smash box office success of Neighbors and the modest success of That Awkward Moment.
- Mr. Fanservice: Takes his shirt off a lot. Is also tricked into taking his shirt off a lot.
- What Could Have Been: There was a long-standing rumor that he would play Light in the American Death Note adaptation, to the point that "Is he [Efron] Kira?" basically became a meme, before Nat Wolff was cast several years later. Rumor has it that he turned down the part citing the need to cast Asian actors as Asian characters, avoiding a Race Lift...the latter of which is exactly what ended up happening.
