* ''Fanfic/VivaLaVida'': Played with in three ways regarding Olive turning to evil.
** The {{Deconstruction}}. Olive gradually makes the switch to evil as the story progresses. While agents turning to the "odd side" is common enough for therapy programs to be created (at least in Precinct 13579) and they can take advantage of the programs if they feel themselves slipping, Olive, who has full knowledge of the assistance available to her, doesn't take advantage of them. Instead, she has to battle her emotions and feelings as she struggles with why she enjoys being around Odd Todd instead of being disgusted with him like everyone else.
** Played straight in the BadEnding, where Olive completely goes to the "odd side" and joins the Todd Squad permanently right after she performs a RedemptionRejection towards Otto.
** Subverted in the GoodEnding, where she has a HeelRealization and decides to quit the Todd Squad, heading back to Precinct 13579 and owning up to what she did.

* Tambryn in ''FanFic/{{Claustrophobia}}'' started off as a nice, well-liked character. [[spoiler: Then she went off the deep end and tried to crucify her ally and district partner Maxim, who was only thirteen.]]

* Many characters in ''FanFic/EquestriaAHistoryRevealed'' end up pulling this trope.
