this Au is being created by me, if you want to use feel free just credit me.
After 20 genocides routes being made, Sans decided he would do something to stop it, he taked dertermination from alphys lab, but Chara was different too, because of Sans act the story had been changed, as Chara find where the monster evacuated and kill all of them reaching LOVE 20 and getting 2 new skills ,one being able to use two welpons at the same time, the another is WIP for now.
Any OC you want to get in this, is gonna need to be accepted, in the information you need to have:
Monster: say the ATK and DEF of the character, and the story behind him.
Human: say the soul/trait he have (Canon or not), and the itens.
All of the OC's need to follow the normal rules here from rule 4 to rule 7 : http://undertale-rp.wikia.com/wiki/Undertale_RP_Wikia:Page_Guidelines#Original_Character_.28OC.29_Pages
Anew!Sans: he still have 1 ATK 1 DEF, can use soul attacks, and change the soul color to any, because of the fires. Because of the determination the attacks are faster, but he is unstable. If you keep fighting he get tired, or even can mealt because of all the determination he is using.
Lv20 Chara: Normally uses The empty gun and the true knife as welpons, as she can hold the two together. As she have lv20 she has 99 Hp. Because of the determination, and the genocides, she can easily dodge sans attacks even they being faster. Gained control of the timeline when reached lv20, she can speak and is more easily pissed than Frisk, is kinda sarcastic sometimes.

Determined frisk: is trapped on the reset screen, can't do nothing as chara is on control. She had done the genocides and corrupted chara to the way she is now. Been trying to reset and do a pacifist to see all of her friends free.
Flowey: Is trying to stop chara as he noticed she wouldn't change, isn't on neither side, just wants revenge from all the times he got killed.
