What does Sans look like in Underhuman?
hehehe, I’ve been waiting for someone to ask so I could info dump!
The thing is… there is no Sans in UnderHuman.
all entities underground are fallen humans, the monsters died out soon after Chara died, Toriel, Asgore, and Asriel were the last surviving Monsters, besides Gaster, who was trying to find a way to make the core work again, but soon, maybe ten minutes after Chara and Asriel died, ended up falling into the Core, dying on impact with a few pieces of his dust ending up in it and scattering across space and time, now ghastly entities cursed to haunt timelines.
Now, the fallen humans could try and escape once Frisk joined them, but they found peace in the Underground. Toriel and Asgore fought after both their children died, and, as you could imagine in such a time of grief, their argument became a physical fight, and they succumbed to wounds soon after they fought. Patience is much more gentle compared to their dead counterpart, though still cunning. Dally (Patience), along with Mars (Bravery), managed to fix the core, supplying themselves, and all future fallen children, with food and access to magic.
so, in short, this is an Au with no monsters present in the underground, with Monster Kind having died out, mainly due to starvation and fights over food, there is no Sans in this Au, he is simply dead, along with the rest of the monsters. The Humans are all bullied kids or outcasts, Chara’s ghost is there too.
