UNDERATK Undertale AU by Yamata41
I didn't want to use Storyshift AU for Ashen Timeline; I decided to make a variant of Chara instead, which gives more originality.
Some concepts of the AU;
Chara and Frisk are siblings; they fall into the unground together. They take the role of Sans & Papyrus.
Gerson Boom takes the role of Asgore, King of the underground.
Sans & Papyrus take the roles of Royal Guards from Undertale Hotland, RG 01 & RG 02.
Also, armor designs were fused with Undyne's Undying Armor.
The Unused Undertale Human takes the role of Frisk.
That's all for now; the rest would be spoilers!
