Evelyn Pines is the 17 year old sister of the Pines twins. Fiercely protective and loyal to her siblings, she is with them during every supernatural event they go through. But when she starts hearing a strange voice in her head, and begins seeing a triangle-like figure, she realizes that there may be more to her and the town than she thought. Eventual BillxOC, eventual AU.

For Monsterkind, the Surface represented freedom. For Frisk, it's a return to some uncomfortable realities. It all began with a simple wish. When that wish faded, Frisk tried to move on. Except, 'moving on' was not so simple. Emerging from the Underground had put them in a worldwide spotlight. From an unknown child, they had become an icon of great value.

What if two humans were in the Underground at once? What if one human was DETERMINED to stop the other? What if they could both SAVE? What happens when an Unstoppable Force meets an Immovable Object? When a certain scientist pulls enough of himself together, he finally finds a way to stop the destruction of his world. All he has to do is break through one wall... (Paranoid rating)

All Hope wants when she takes her sister and runs away from home is to be as far from her abusive father as possible. The last thing she expects is to fall down the hole on top of Mt. Ebott. Now she must venture forth, battling internal and external monsters that threaten everything she holds dear. Disclaimer: I do not own Undertale. Rated T for sensitive content.

Looking for closure after finishing the game you write a letter to the characters. You never expected a reply.

Two Gems can fuse into one, but Pearl learns firsthand that a single Gem can also be split into two entities.

After the events of "Tally Up Your Sins," you and Sans have to learn to live with your pasts and figure out how to move forward, all while unraveling a mystery that dates back to the first war between humans and monsters. (Part 2 of the "Still Counting" series) (Rated T for: body horror, graphic violence)

Frisk was living on the surface with their new family. Everything was perfect except, the dreams that seem to belong to someone else. Something is left undone. The past is pulling them back. The world is reset, everything is undone. Somehow, they have to break the cycle and save everyone, and themselves. (pacifist run spoilers)

"Out in the Arctic Ocean, an old man dreamed of stars and trees." Simple series of vignettes about family, and what it means to a certain curmudgeon we all know (and love). Hurt/comfort, rated for some unpleasantness (implied child abuse/panic attacks/suicidal thoughts).

Sans only has 1 HP, what if Papyrus accidentally hurt him? Short, sweet, and a bit sad. No character death. The skelebros are children in this story.

Dipper is bitten by a venomous creature and his family must race against the clock to save his life.

Set in the universe of War of the Guardians and taking place after Children of the Night, these are the continuing adventures of Jenny, the Doctor's Daughter.

"'We're all family here, right? Since I'll get to be this li'l gremlin's Grunkle and all.' '...oh," Soos said, 'but you can't be a Grunkle, Mr. Pines.'" Post-finale fluff, because seriously, we can never have enough post-finale fluff in this fandom.

(post-finale) Life after an insane Dorito-induced apocalypse isn't always rainbows and puppies. Thankfully, if there was one thing the Pines family could do (other than jumpstarting said apocalypse), it was to watch each other's backs. Simple family fluff sprinkled with some minor angst. Because the best cakes are made with love, sweat and tears (as Mabel would wisely put it).

Monsters weren't doin so good, ain't been doin good since the war but that don't mean things ever got easy. Until prohibition mind, now that was a stroke of luck, the Dreemurr family was one of the first to start runnin booze. Doesn't mean there aren't those who'd try to cut in on the profits, but that's where a few bones and a lotta bullets come in. Mobster AU, Sans pov, no mercy.

an amazing story
