There where two separate Universes that seemed to switch places. Only problem is, that only two people remember their past life and they're in the wrong universe. Can these two survive in each other's world, or will they ruin they're lives forever?

Digamos que tenemos distintos universos, bueno, hagamoslo más divertido. Juntemos a todos en uno sólo, no creen que algo interesante puede salir de esto? El comienzo de un universo que voy a crear con varias cosas. Steven Universe, Star vs las fuerzas del mal, Undertale, Subnautica, Boku no hero academia y otros más Esta historia va a tratar de Steven Universe y Undertale

Basically Underfell with Steven Universe characters.

Steven tras un evento traumático de su infancia descubre nuevos poderes para evitar que las gemas del planeta madre conquisten la tierra (Steven con los poderes de Betty noir Au Glichtale)

A young orphaned girl is done. She falls down a hole. What she finds will forever change her life.

Chara Dreemurr and her twin sister Frisk Dreemurr go to Inside Falls spend the summer with their grauntie Pearl Crystal Dreemurr. At first,it starts like any boring summer. That is,until Chara finds a mysterious book which the cover is two gemstones of red and blue color with a number '3' between them... (A Gravity Falls AU and Multi-crossover.)

My longest Story yet and my first SU Fanfic. Please note this has been in development since mid-last year (2018) so the characters and settings will not be the same as what ever they currently are by the time you read this. Either way, I've put a lot of time and effort into this so I hope you enjoy. If demand is popular enough I may make a sequel at a later point but no guaranties.

Steven and the Gems went to stop a gem mutant. But something went wrong and Steven and Emerald fell underground. What new adventure a waits Steven underground. Will he make friends or enemies. ( I don't own Steven Universe or Undertale but I own my OC.)

Empress Gail is an amalgamation of seasons 4 and 6. Also, get it? See what I did there? The tittle is a reference to Empress Theresa.

The evil Alt Right has decided to invade Charlottesville once again! This time, they want to install Donald Trump statues all over the town! But Steven Universe and Sans won't let them do that without a fight!

Steven is sent to Mt. Ebott to investigate. He ends up bringing something home...

i owe this all to my friend for introducing me to this show and game. they're freaking awesome. if you're reading this then you totally agree. the title says it all. the worlds of Undertale and Steven universe meet together In one incredible adventure. Please enjoy and leave comments ;)

This is my first fan-fic EVER so don't judge to hard. AND Enjoi! Oh and it is the Undertale routes but I have my own little SU twists and stuff ;)

Steven and Amethyst mean the skeleton bros, Sans and Papyrus!

Orphan isn't something you are born as, its something you become. In a recent tragedy, Papyrus has now become this very unforgettable word. Will it all be for nothing? What will he make of his life after he lost people whom he loved. Does Stephan Universe have anything to do with the murders? Only one way to find out...

After freeing the monsters, Frisk decides to take his friends on a vacation to Beach City.

Go check out the first one before this ok now enjoi!

If Steven expected to have a nice, calm day to spend with Connie, he's dead wrong. (Cruddy so far, may remake it.)

A story that narrates what could had happened if gems existed instead of monsters. After the long, sorrowful war between humans and gems several events took place over the years.

Two worlds. Five and a half gems. Eight and a half monsters. Three humans. One little yellow flower. And an experience that none of them would ever forget.

So, thanks to Caesar's Palace, I'm in the swing of things again. These are just one shots that have been compiled into a book of tales! Some of them may be bad but hey! Sometimes writers have bad ideas! Hope you like it!

Frisk was just taking Flowey up to the surface. normal Flowey Pot AU stuff right? but when Frisk reaches Waterfall a mysterious pink lion arrived carrying someone Frisk thought they'd never see again. Flowey Pot AU!

What happens when your 2 favorite fandoms combine? Watch as Garnet, Amethyst, Pearl, Peridot, Lapis, Jasper, Connie, and Steven play Undertale! Rated T for some swearing. I do not own Steven Universe or Undertale

(I did not write this story, my friends did.) Steven and Connie are having a normal day, until the warp pads bring them to a big mountain. They climb up the mountain, looking for an exit, before a strong force throws them into a deep hole leading to a place full of mystery... Credit to EpicT02 for writing this story :3 STEVEN UNIVERSE AND UNDERTALE AU

After Steven and Pearl had free the monsters of the Underground. They thought their journey was over. Yet there is someone else hiding behind the darkness other then Flowey. The one who wants to destroy humanity! With the help of an old friend and the power of Determination. Nothing can get in the way of good!
