A simple question arose one day. What happens if some fandoms and their events take place in the same universe, on the same planet and in the same world, while somehow intersecting with each other? Now with this answer I want to share with you. It all started with a kind fairy tale, telling about friendship and kindness, and a family where there is a child who owns a power that...

After the events of Undertale, peace has been brought to the above ground and a new nation is formed. However, a Ebott science project goes wrong, Frisk going missing in the process and ending up in a strange new world. Sans going in to save them, what comes next is filled with slice of life fun and jaw dropping action.

A series of one shots where I give Frederick and Sotpf!Freddie(Ember) actual good friends and found families that care for him. I take suggestions from readers on what characters you'd like to see our depressed prince/princess befriend and or be adopted by. I also take suggestions from Tumblr @yaminobean.

Stories speak of a mountain where children have gone and never returned, unknown of the mystery which lies within it. Now history repeats itself as a child falls but with a twist as another joins...and to think a mild stroll got him into something thought of as fairy tales.

Mt Abott suddenly appears out of nowhere and Cuphead, dragging Mugman along, runs to the mountain to investigate. Soon they fall into the chasm and are attacked by the monsters of the underground. As they explore, they discover a tragedy that befell the underground, make friends along the way, and have a bro jolly fun adventure of a lifetime. Cover photo by me.

Finally finding an escape from the world of Don't Starve, Wilson finds himself in a world unfamilliar from the one he knew before. He isn't alone, though, Frisk and the monsters he calls his family will be there. Somehow... Wilson P. Higgsbury knows this won't be as easy as keeping himself alive in his old prison.

Ever since Toby Fox made the RPG game know as Undertale 5 years ago, many people made their own versions of it, known as AUs, or Alternate Universes. Here is my AU, which stars a most likely forgotten character from the Pokemon Adventures Manga: Yellow. This is also kind of takes place after a whole bunch of stories that expand on Yellow's character. Hope you enjoy!

Ruby Rose recognized that person in the tree. They certainly stood out with their disheveled hair, tattered yellow and green shirt and sharp red eyes; yet she couldn't place where she had seen them before. They also had a strange name, and coming from a family with names like theirs that was saying something. Really, who names their child Chara? What kind of color is that?

Compa and Iffy were discovering a new mountain called mount Ebbot but they wind up falling into the cavern where the monsters reside. Would they have to fight to get free, or are these monsters not like the ones in Gamindustri? Will the folks in Gamindustri try to save them? Is there a dark secret in these Caverns? Will the two girls know what to do when the time comes?

After freeing the monsters from the Underground what's next for young Frisk? Well, there's always the world's most popular trading card game Duel Monsters. With a deck based off of her adventures it's time for the monster ambassador to show everyone what she's made of. Though with dark forces around every corner, she'll need to remember one thing, always stay determined.

I don't own Undertale or MHA. They are owned by Toby Fox and Kohei Horikoshi respectively. I'm rather garbage at summaries and descriptions, so I guess you'll have to read to find out.

Sans has gotten himself stuck in the void between worlds in a successful attempt to stop the resets of his timeline. He's not sure how long he's been chillin' alone there, but eventually a chance at escape stumbles his way in from the Veil of Death. His name?—Sirius Black. (no pairings)

Frisk used the reset button, but it glitched and instead of resting like normal. Everything reset to a new and different world. Sans, Papyrus, and the other Monsters were brought along too. Frisk was not sure what was going on at first but she soon figures out where they were.

They just wanted to be themselves. Their parents didn't listen. They didn't understand. When their parents wanted to send them to a conversion camp, they decided it was time to run away. After an incident in the nearest national park, they find themselves in world of monsters and magic. Then, along their journey, they make friends and find themselves too.

After fighting in Chara's genocide run for what seemed like a lifetime now, Sans devised a new plan to get rid of the wraith, in the hopes of giving his brother a happier life. In doing so, there were unintentional side effects and Sans found himself in an entirely new world. Undertale—more specifically, Sans, meet the Marvel Cinematic Universe.
