#sansnomaly

Guess what. It's Sans x Player, Sansnomaly, or whatever you wanna call it. Uh oh! How did undertale player get into deltarune?

Thank you.

in corestrings though, Gaster acknowledges that the character you play isn't YOU. you, the player, are a completely seperate entity that lives in a seperate plane of reality where the only way you can interact with Gaster is to play the game. which is what a lot of self-shippers do when they want to interact with their f/o (which includes every media - books, movies, games, manga, comics, etc etc)! but in those cases, the f/o doesn't really know you exist because of the limitations of the media! but Gaster does!!!! he knows we exist and talks to us!!!!! as us!!!!!!!

it's strange to think about lol

i think it's also why Sans is so loved. Undertale as a whole (as well as Deltarune) knows there is a seperate entity playing as Frisk. only Frisk, Flowey and Chara ever acknowledge it (Frisk as the protagonist just knows, Flowey with his determination/end of True Pacifist where he asks us to let Frisk live their life, and Chara at the end of Genocide). to my knowledge, Sans and the others don't realise there's someone else other than Frisk. even in Sans' fight on the Genocide route, everything he says about the anomaly and resets doesn't suggest he knows about the player. he thinks the anomaly is Frisk.

it can be interpreted that he knows though! and i think that's part of why people are so drawn to him compared to other characters. he is one of the only characters in the whole game that might potentially know there is someone else there other than Frisk. and that knowledge of us existing outside of their world as an entity that can never truly be a part of it is sort of comforting in a way. Sans because of his circumstances inherently knows the limitations that come with self-shipping. we don't exist in his world, he doesn't exist in ours. long-distance relationship extreme edition ✌️

it's part of why i like sansnomaly so much. instead of just inserting myself into the world of Undertale as either a self insert or an oc, I can just exist as myself. i don't need to insert myself, i can just be myself if that makes sense? because the nature of Undertale is that it knows we're there without having to give us a character at all. you are the character. as yourself.

I had a sudden rush of inspiration thanks to your ask, @cranberrytea451
