So, as I said in the summary, this will be a collection of various requests that I have for reaction fan fictions. This will be the first video game reaction fan fiction I will be requesting.
There will not be many specifications, however these are the minimum specifications you must meet: Have Sans, Papyrus, Undyne, Alphys, Asgore, Toriel, the Mad Dummy, Flowey/Asriel, Chara, Frisk, Metaton, and any other notable character you can think of. Alternatively, you could also add all of the important minor characters too, as in ones that have an actual position in the story rather than just being people you can have dialogue with. Make sure the reactions are realistic and true to character, and perhaps after all three routes are reacted to, you can even explore Gaster a little bit. Of course, go in order from Neutral to Pacifist, and Pacifist to Genocide. Just have the characters that are reacting be from the Neutral route or the Pacifist route. Don't add the characters from the Genocide route into the reactors, as that would ruin a lot of other reactions.
