Toxtale

Toxtale is an au that portrays a bleak future fo humanity. Due to the fact nuclear warfare became so bad, it created “monsters”. Humans, scared of the monsters sent their best soldier to go and relay information. He safely goes down to the toxic pit with a mask and carrier. But something went wrong! The carrier crashed leaving him stuck. The only other exit is at the very end of the toxic kingdom with a bunch of monsters. Frisk went in, and through out his journey he became empathetic to the monsters. He didnt’t want to relay ANY information. But if he didn’t the consequences would be severe.

General personality
Monsters in this au act slightly more like monsters. Almost all the monsters hate humans. Politics are bought up alot more. (sans hates politics but his brother is intrested in it) Monsters haven’t had a single soul so the king wanted to use the human as a way to make some sort of treaty. But the human is a specially trained soldier, he won’t go down without a fight.
