Sharpay counts within the standards of a G-Rated Romantic film genre as she creates the conflict of the series with the immoral intent of sabotaging Gabriella's relationship with Troy. With the harmful intent, she possesses qualities similiar to other villains in romantic genres (specifically lover stealers and queen bees) such as:

Envy: Envies Gabriela for attention in the first movie and relation with Troy that she goes out of her way to  sabotage their relationship.

Lust: Mostly in the sequel, she seeks Troy's affections despite him being in love with Gabriella Among other things, mistreated Gabriella and her friends especially Kelsi, stole a duet that Kelsi written for Troy and Gabriella, abandoned her brother's performance for her selfish desire (ruining his hardwork which Gabriella pointed out later), and used her wealth and connections to get Gabriella and other Wildcats banned from participating just to steal Troy and win the Star Dazzling Awards (I suppose it could be bribery and cheating considering that she used her wealth and connections to get Troy's boss to carry it out who works for Sharpay's father) . Gabriella even pointed out in the movie that Sharpay's actions not only ruin her summer but her friends' as well. She could also be a Bond Destroyer because she did ruin Troy's relationship with Gabriella for a while in the sequel movie. In short, she's pretty much a Queen Bee within the standards of a G-Rated Romantic Comedy film. Her actress called her character the bad girl and compared her to Rachel MacAdam's character in Mean Girls (Regina George) in an interview on The View (for supporting evidence). I suppose it might not be much but it shows a manner that we know is immoral instead of being stupid or unpleasant (Johnny Bravo). At the very least, she could fit under Villains by Proxy.
