Big Undertale and FNaF fan, got lots of ideas...
So I'm gonna put a list of the stories I haven't written yet and what they are about.

A Soul of Void:
A human named Jack dies and is sent into the reincarnation cycle, but he somehow escapes it. Going through the demon realm fighting both good and evil to keep his soul and his found friends.

Space Crimes:
Humans have decided to send people who commit the worst crimes, those who are insane, and those who have gotten in the government's way but of corse they send our poor mostly innocent protagonist out into space not knowing that all the humans have been making their way to a alien planet. Will our protagonist survive brigands, aliens, and the world around them? We will see

And a few undertale aus:
GoldTale
UnderFallen
ForgottenVoice
FellSwap-F(lare)
Flareverse
AIgeneratedTale

I think that's everything
