MLP/Undertale crossover.
Not a PWNY-verse story.

Long ago, the Monsters and Humans fought a great war. The Monsters lost, and were sealed in the Underground. It would take the power of seven human souls to break the barrier that kept them imprisoned. They only had six. And so the Monsters waited and hoped, praying that another human would find their way to the Underground. Some thought the seventh soul would give their King the strength to break the barrier. Some dreamed of a human who would be their friend, and save them all...or had nightmares of one who would bring back the war.

...but nobody came.

...but somepony did.

Eons after the war, with no way to tell how much time had passed above, a tiny blue filly with wings and horn fell into the underground, calling for her Mama. None knew the poor creature's nature or origins...but her soul was powerful with magic, even more so than a human soul.

None can know what will come...of this little 'Woona'.

Slight Undertale/MLP crossover.

One day, while collecting wild vegetables in the Everfree Forest, Fluttershy encounters a strange, sentient flower going by the name of "Flowey," and the two become fast friends. After taking him home with her and letting him get to know her other pals, they begin to suspect that this plant, his cheerful personality, and his ulterior motives might not be all they truly seem, despite Fluttershy's claims on the contrary...

The Human has ravaged the Underground, they killed every monster they saw, never sparing one from death. They were cold and were merciless as they progressed through the caves, no sympathy towards those who gave the option to do so otherwise.

But they forgot about a certain somepony back in the cold village...

And she's here to have a 'talk' with the Human.

This story is a sequel to Starlight Glimmer gets dunked on

Starlight is absolutely engulfed with rage. Because of her naivety, she expected Sans to actually spare her when she played the Genocide route. Still reeling from her failure to beat him last time, and having nightmares that taunt her over this, one thing is for certain. She won't be making the mistake of showing him mercy again, no matter how bad it makes her look.

It's too bad Twilight has left her uninformed about what happens AFTER Sans. Otherwise, Starlight would've let it be.

Note from Author: This will probably be a pretty short fic.

Sort of a crossover with Undertale. Contains spoilers for Undertale's Genocide route

Reading the first fic is recommended.

Frisk and her friends have finnaly escaped the Underground, but they didn't walk out onto earth. They......heh, you get the idea.

*Crossover with Undertale and takes place after True Pacifist ending.
Takes place after Mlp season 5 finale*
