Basic Plot: It is a true pacifist run, the first run of this Universe. Frisk has already defeated Omega Flowey and all that. Sans is taking a short stroll through the core, making sure it is safe enough for Frisk to make it through on their own again, keeping his promise to Toriel, as he has the entire time. Then, a “glitch” or “error” occurs in the universe, an anomaly occurs. A portal/rift suddenly and violently opens up and forcibly sucks Sans through it. He is tossed into a random alternate Undertale AU. At first, Sans is understandably confused, but soon figures out the general jist of what happened. Later, he discovers that he can now open up portals to other dimensions (limited to Undertale AU’s), but doesn’t know “where” his is, and is forced to make “random jumps” to try and find it. He is exactly like original Sans (at the start of the story), and looks the same except for the fact that his clothing is slowly getting more and more tattered. Meanwhile, back in his universe, Papyrus makes a call to Frisk, saying he can’t find Sans and to tell him to come over if they see or find him, Papyrus is not really worried yet. Frisk takes care of everything else besides facing Asgore again and looks for Sans, They look everywhere but can’t find him. They continue and complete the true pacifist run(yes, it still works out without Sans’ souls for Flowey to steal), but Sans is still missing and Papyrus starts getting worried and sad. Frisk looks again, for a very LOOOOOONG time, but can’t find him. They are heartbroken to see Papyrus so sad, and they think they missed something or messed up somehow. They reset and go through everything in the ruins again, except Sans doesn't show up this time, Frisk looks around everywhere, worried. They try resetting again, and they repeat this cycle many, many times. They soon start getting worried that they permanently messed up by resetting that first time, and blames themselves for permanently ruining their(everyone else’s) happy ending. They try true pacifist again a few times, but end resetting again to try and fix it again. They slowly start driving themselves insane.
