Cosmic Calamity

*Undertale Yellow AU Time!! :333 Half of my hyperfixation is on Star specifically sooo I made an AU centered around him

*Certain things are subject to change depending on if my feelings change/feedback

*This NOT a ship AU. Star is in his early-mid 20s during UTY and his late 20s-early 30s during UT, Flowey is stuck as a 13-ish year old. Just felt the need to clarify that.

Contains Spoilers for UTY below! (Geno and True Pacifist)

*Basically, Clover has been being possessed by the PLAYER, and has been doing multiple genocide runs. PLAYER gets more and more influence each reset, and this time, they managed to kill Martlet before she escaped

*Flowey has been growing tired of the genocide routes. Isn’t Clover bored now? But now they killed Martlet before she escaped, that was new. He didn’t want to admit it, but he was kinda scared. Before he knew exactly what to predict, just playing along in hopes Clover would get bored and do a different route, one which hopefully ended in him getting his souls. But now he didn’t know what to predict.

*In this timeline, word never reaches the Wild East about Clover, so everyone is blissfully unaware of their genocide. It plays out like it does normally, but with Clover killing citizens of the Wild East while everyone’s back was turned. Star believes that everyone is just… away from town, they’ll probably be back eventually. Ceroba grows suspicious of Clover, she managed to get some people to evacuate, but fails to convince Star in time. Star returns from the mines just in time to see Clover kill the Feisty Four. Ceroba fights Clover to stall for time, telling Star to run. He refuses, he has to avenge his town, it’s his duty as a Sheriff. Ceroba forces him to run away, shoving him out of the gate and closing it. PLAYER tries to go back and kill Star, but he’s already gone, Flowey forces them to forget about it and move on to the Steamworks. After they oblige and go to the Steamworks, Flowey considers his options. The timeline had already been changed, so why wouldn’t he change it more? The last two monsters who stood so much as a chance against Clover would be Axis and Starlo. Axis would probably try to kill Flowey, plus, he’s technically not a monster, so Flowey went to go find Starlo. He finds Starlo and explains everything, the resets, saving, loading, timelines, all of it. Flowey wants to put an end to it, but he doesn’t know how. He could just reset now, but would that really do anything? Clover would just come back and do genocide all over again. Sure, his main motivation for stopping the resets is just wanting the human souls, but Starlo doesn’t need to know that. Starlo and Flowey agree to work together to try and stop Clover.

*The genocide route continues as normal, by now, Clover is lv. 20, they’re in control now. But when Clover approaches the castle, Starlo is there. So is Flowey, they give exposition and fight Clover.

*The first phase of this hypothetical fight wouldn’t be too insanely hard, easier than the Zenith of Monsterkind at the least. Starlo tanks hits for Flowey, and eventually when Starlo would get to around 1/5th of his HP, Flowey realizes they’re not strong enough on their own, and leaves, promising to be as quick as possible.

*This part of the fight would be much easier, but when you ‘kill’ Starlo, before he turns to dust, Flowey returns with the human souls. He grabs Starlo and shoves the souls into him. He also indirectly causes himself to also fuse with Starlo, forming the Blazing Star (like the warrior cat book….omg…)

*PLAYER is determined, but so are they. Now it seems to be a battle of who can outlast the other. Essentially a purgatory for Clover. PLAYER and the Blazing Star would all be fighting for control of the timeline. There’d probably be an ending where the PLAYER wins, but that’s boring and lame. So the Blazing Star (mainly Flowey) would begin to question how this 12 year old is still managing to grip a hold on the timeline when they’re facing what’s pretty much a god. He realizes that there’s a second party at play. Clover isn’t more determined than them, far from it, it’s someone else. Someone neither human, nor monster.

*The Blazing Star tries to get Clover to resist the player, and eventually, they do. The threes combined efforts manage to split PLAYER from Clovers soul. They destroy PLAYERs connection to their world and reset the timeline.

*Clover has very few memories of that timeline, only that Flowey and Starlo helped them when they needed it most. Starlo has some memories of it, he mostly remembers everything but some parts are fuzzy, namely the logistics of saving and the timelines as well as most of the stuff before the final fight. Flowey however remembers it clearly.

*Clover does the true pacifist ending and everything stays pretty much the same, but Starlo and Flowey are friends now.

*After Clover gives up their soul, Flowey lets them rest. 10-ish years pass, and Flowey panics since he lost control of the timeline again. He goes to see if another human fell, he’s still been checking every day since he still wants those souls. But low and behold it’s everyone’s favorite yellow skinned gremlin, Frisk.

*Flowey recognizes Charas presence, and Frisks story plays out largely the same. Though I do want to add in a Wild East section, not too sure what’s gonna happen or how Frisk gets there though. However, Starlo would be a wee bit suspicious of Frisk due to sensing that secondary presence (Chara) in their soul, but would realize that regardless of who or what it is, Frisk is indefinitely better than PLAYER.

*Flowey also cut off contact with Starlo after Frisk fell, believing he wouldn’t understand why it was so important that Frisk stayed alive.

*And then after the Asriel fight Starlo and Flowey make up and become friends again YAY good ending

*anyways here’s a concept for the blazing stars design:
