!!Other tropes related to to K. A. Applegate:

* ApprovalOfGod: She's been very supportive of ''Animorphs'' fandom. Except the artwork of Tobias doing it with Harry Potter.
* CreatorCouple: With Creator/MichaelGrant in ''Literature/{{Animorphs}}'', ''Literature/{{Everworld}}'', ''Literature/{{Remnants}}'', ''Making Out'', and ''Literature/EveAndAdam''.
* DearNegativeReader: She [[http://web.archive.org/web/20010807200502/www.morphz.com/posts/1061001.htm wrote a letter]] to the Animorphs fans who didn't like the ending. Even if you think the ending was bad, you have to admit that the letter was pretty fucking awesome.
* DigitalPiracyIsEvil: Averted - in 2011, when the ''Animorphs'' books were still out of print, [[http://www.reddit.com/r/IAmA/comments/gzhau/iam_ka_applegate_author_of_animorphs_and_many/c1rfte1 she stated she had no objection to people continuing to circulate them as free ebooks]]. She would've preferred to have them officially available for sale in ebook form, but it wasn't something Scholastic was actively doing at the time.
* GenreAdultery: She commits it all over the place. A little-known fact is that Animorphs wasn't her debut - she wrote YA realistic romance novels before that, making Animorphs, a sci-fi series, different in every way possible. Then, after Remnants, she started working on more literary works; none of them are at all similar to her late '90's, early '00's series. Then she committed adultery on ''that'' genre when she co-wrote ''Eve and Adam'' with her husband. And that's not even mentioning her chapter books for beginner readers. Basically, she's a really, really versatile writer who has no one single genre.
* KeepCirculatingTheTapes: This is what she wants Animorphs fans to do.
* MoustacheDePlume: Ambiguous initials sub-type. Her full name is Katherine Alice Applegate.
* OldShame: Back in TheNineties, she wrote ''Barf-O-Rama'', which is exactly what it sounds like based on the name: disgusting books built around barf scenes. For obvious reasons, it was done under a pseudonym.
** Really, anything she did before Animorphs. And even then, she didn't like the endings of ''Everworld'' and ''Remnants'' any more than her fans did.
* [[HeAlsoDid She Also Didů]]: Applegate was a ghostwriter for Sweet Valley Twins, a SpinOff of SweetValleyHigh, before she started writing her own books.
