Katzsoa is a fanfiction writer whose obsessions are sporadic and frequently-changing—there will be a sudden burst of activity in whatever story subject she's into at the moment, and then dead air for months. Stories used include Doctor Who, Alice in Wonderland (2010), Rune Factory 3, Portal, The Hunger Games, Ni GHTS Into Dreams, Sherlock, Axis Powers Hetalia, and others.
Tropes in Katzsoa's fanfiction:
- Action Girl: Michaela, the genderflipped protagonist of Rune Factory 3 fic Beyond the Races.
- Break the Cutie: Oh so much in Beating the Odds, most notably with Briar and Kayla.
- Dark Action Girl: Shimmer Argent's general psychopathy knocks her into this category.
- Death Is Cheap: The students at OFU:ASFES have no reason to fear death. GLaDOS saved backups.
- Face Palm: Done by Agent Katz at least once in OFU:ASFES, and by Shere Khan, of all people, in Tiger and Tigger.
- Good Cop/Bad Cop: Lampshaded in OFU:ASFES—Lanyon thinks that the Agents are trying to pull this off, Katz as the Good and Alix as the Bad, but Alix and Katz's personalities clash even when there are no students to scare.
- Major General Song: Timey Wimey Major General, a short rant about "Father's Day".
- Official Fanfiction University: The Aperture Science Fanfiction Enrichment Seminar.
- Recursive Fanfiction: After the Game, for jjhatter's The Final Game of Cat and Mouse. The story morphed into a co-written series, with jjhatter writing A New Game as the third installment and katzsoa adding Nothing's Making Sense as the fourth.
- Song Fic: Thinking of Him and I'm Not That Girl
- Warrior Poet: Kayla Rakkor—she always was the poet; the "warrior" part develops as the Games progress.
