After the barrier on the Underground, the monsters come out but to only be feared by humans. They decide that they will live on MT EBOT, away from the humans so that they do not disturb them. Sans volunteered to go get everything the monsters needed when they needed it. So when a certain skeleton with pink slippers and a blue jacket makes it to the internet and catches the eye of Nick Fury as a potential threat, things get weird. (PS) I do not own Avengers, Undertale, or any of the pictures that might be posted. This is also just a continued version of the original.

Frisk's POV "Where are we and why are we here?" "dunno, kid. Maybe in an anti-void?" Star's POV "I don't think this is the right portal, Star. I'll try another one." "No. We should try this one! Maybe this is a new portal and perhaps it has many new creatures there. And besides, you like knowing new things, right?" Dipper's POV "I thought this was already the shack." "I thought so too. I was ready to run back to it." "Hey, who's that?" "Maybe we should check her out." -------------- This story is inspired by Undertale, Gravity Falls and SVTFOE. This is my very first story so I'm sorry for the mistakes. ANYWAY, enjoy reading my story. I hope you'll like it. COMPLETE CHAPTERS Finished: May 4, 2019

Spoilers for after Undertale and after Gravity Falls! The twins are coming back to Gravity Falls for their winter break. However. The mountain just by Gravity Falls had a strange event a few weeks after the twins left. Monsters from the fabled "Underground" started coming out of Mt Ebott. With their savior, Frisk. Now Frisk and their monster family live peacefully in the nearby town of Gravity Falls. What shenanigans will the twins get up to this time? What will they discover? *This takes place after Gravity Falls' Finale and Undertale's True Pacifist ending!* The original Gravitytale idea as well as the intro music used was made by the amazing Jeffrey Watkins. Check them out on Youtube and their story on AO3! I thank them for inspiring me to make my own fanfiction. This is my first story and first time writing a story, it might not be any good, but do enjoy!
