My Trans Undertale Fanfics on AO3
In light of recent events in the fandom, I thought I would offer some transgender positivity and representation by sharing my Undertale fics I've made about transgender themes, both for characters in the game and reader perspectives. All trans people and identities deserve to be respected for who they are, no exceptions. The characters of Undertale are understanding listeners that would support trans people in their own lovely ways, and there's plenty of trans themes in the game as well that many other content creators have explored.
Gender-Switching Scapulas: Sans accidentally eats a sandwich injected with a substance Alphys has made to give trans people temporarily relief as their true selves while they work through their transitions. It gives Sans the body of a female skeleton for the rest of the day, and she soon finds it to be rather comfortable and freeing. https://archiveofourown.org/works/44578051
Out of a Bind - Papyrus, who's come to realize after emerging to the surface that they're non-binary, is leading a rally for their city's government to vote yes to allowing non-binary gender markers on IDs. You're their special someone, and you help them make the rally possible while soaking up all of their Papyrus-ness in the process. https://archiveofourown.org/works/32164585
Bone-ary Breaker - Non-binary AMAB reader perspective where you open up to Sans, your boyfriend, about your gender identity and not wanting to hurt what you have with him, only to be showered with support; both from him, and from a certain fish lady over the phone. https://archiveofourown.org/works/23791645
Hormones and a Hot Dog - Trans female reader perspective with you celebrating three months on hormones by going to a Chicago-style diner with Sans to satisfy those salt cravings. https://archiveofourown.org/works/30165534
Bathing in Freedom - Trans female reader perspective where you've made enough progress with hormones to try a bathing suit that you feel at home in; once you and Sans have purchased it, you take a trip to a public pool for a sans-ational time of being yourself out and about. https://archiveofourown.org/works/32311720
If any of these fics sound like enjoyable reads to you, I hope you have a great time with them! The Undertale fandom should be a place for all people and identities to have their space and representation in, just as every other fandom should. Don't let anyone tell you otherwise.
