crossover fanfiction percyjackson undertale

After a failed Genocide Run,  the reset glitches. Frisk finds themself in a black void and a group of 7 familiar demigods fall into what remained of the underground. It takes a while for Sans to overcome his injuries and realize that the reset hadn't worked. He ventures the underground in grief to find a gathering of children. Human children. The demigods came here after Chiron told them something felt off around the area. Meeting a mysterious, punny skeleton was unnerving, but there seems to be a darker force around them...

Dual Stones - Undertale Fanfiction (COMPLETED) by IcyDuelist

Duska has something most people would call a traumatizing childhood which she only escaped from a few months ago. Now she finds herself beneath the very mountain she was born in with monsters around every corner. She decides to start her life again here, in the house with Papyrus and Sans, but monsters don't live the most ordinary of lives either. Duska's past is catching up with her but the wall of friends in front of her may be hit by the impact first. No pictures, videos or any other media belong to me unless specifically said. Will have some swearing in it. Undertale belongs to Toby Fox. Thank you for creating such a beautiful game! I FINALLY FINISHED IT!!!

Grouptale [Undertale AU] by FridayHater

What if the six fallen humans who died before Frisk never died and instead joined Frisk on their journey through the Underground? It all seems good... aside from Frisk. Why are they really in this timeline? What do they want? Join the other six as they try to learn about 'the eighth human', why everything is so strange and how to escape the underground. [Cringe artwork by me]

(OLD) Devil May Cry: Titanomachia Part 3: Awaken the Demon (pjo x dmc) by J_deano_118

Six months ago. Thalia Grace was revived, leading there to be a lot of discourse about who the child of prophecy. However now, we have a lot more pressing matters to handle. This time. This quest. I'm not returning the same. I have a bad feeling about that. Show time.

The Afton and The Orphan (FNAF and Undertale crossover) by ccmcdaniel2

This is a sequel of my BATIM and FNAF crossover book, Nostalgias Collide, if you haven't read it yet, read it first. It's been weeks since the Afton kids had met Bendy and freed them from their studio prison. However, there is another kingdom that need to be saved. Chris Afton, the youngest of the kids, will be the first to do the job. After Micheal told him the story about a monster kingdom underground that he remembered their mom told him at Chris' age, Chris ends up falling down the same hole that Micheal told him to beware. Freaked out, Micheal sends their group of friends to get him but Chris meets another boy down there who seem to fall before him and they work together to either fight monsters or spare them all. Disclaimer, FNAF belongs to Scott Cawthon and Undertale belongs to Toby Foxx. I don't own them or most of the pictures that appear in this story but the picture of the kids in the title I drew myself. This story will be told like the entire Undertale game but I will add some original parts.
