This is a good hefty crossover taking place (vaguely) in the universe of High School of the Dead. Included canons currently include Parysite, JoJo's Bizarre Adventure, and Portal, but they may expand in the future. With the undead tearing through the world's population, who could possibly hope to survive?

A trail of vengeance, just like before. So much blood, but... Isn't that what he'd always been paid to deal with? Paid or not... the Demo Samurai wasn't about to sit back and watch his team get slaughtered, not without vengeance. He didn't care about being Number One. He just wanted Justice... He wanted Justice DEAD.

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.

The Underground wasn't built in a day, but it fell in one. In the end, with dust all around, it was the two weakest monsters in the Underground that were left for each other. But, honestly, what was really left? Rated T for canon character death, suicide mention, and mature themes.

Sans had been having a bad couple of days. But things get much worse when he discovers that everything he knows and loves has just been torn apart. When the one responsible for it ends up being too much to handle, Sans has to look for help in unlikely places. CROSSOVER: Sans hooks up with plenty of slasher movie characters in this one, so expect gore and language.

The Error was finally getting serious. He had to find Gaster, and he was going to do it. And Gaster was getting tired. He'd run and he'd run and he'd run and he was tired of running. And so he stopped running. But he couldn't beat the Error on his own. He needed help. ... And what's better than an army of Sanses? This story revolves around Gaster, Swap! Sans, and two OC Sanses.

They've never seen anything like it. Nine elite soldiers that rivaled even them. The RED team was scattered before the battle even began. They will rally. They will fight. But can they survive? Rated T for violence and language.

One day, Sans, Sans, Sans, and Sans got together to have a party. They planned on eating quiches, playing cards, catching up, and pretty much doing nothing else. And that is literally exactly what happened. Starring Under! Sans, Edgy! Sans, Swap! Sans, Geno! Sans, Metta! Sci! Sans, After! Sans, Reaper! Sans, and eventually literally every single AU Sans I've ever heard of.

*DETERMINATION. You will fight together, or die alone.

Ultron was the most dangerous being on the planet, and the Avengers were doing everything they could to track him down and destroy him. And now he had simply busted down their door and walked in. This seemed like another run-of-the-mill supervillain attack, but was all as it seemed? Technically a Fourth of July special. One shot.

48 characters. 12 universes (Actually more like 20, but I grouped a few together.) Translating a randomized Hunger Games simulator into an actual fanfiction was difficult, but fun, and has managed to become a rather epic and goofy crossover. This is gonna be SUPER long, FYI. Undertale, DBZ, Marvel, DC, MMX, OPM, Street Fighter, Mortal Kombat, Star Wars, and more. (Character limit)

Threats from Underground, they expected. Threats from the Surface, they expected. But threats from space? Most of the monsters didn't even know that space existed, much less that people could live in it. But the Gems knew that the Monsters existed. They needed a planet to mine. And with one hero true hero fallen, there is only one monster left who can stand up to the Gems.

One day, long ago, Sans the skeleton was forced to make an impossible choice. His decision would change everything.

Frisk and Sans experience some divine intervention in my own reimagining of the ReaperTale AU. AU 01 spinoff.

When a Genocidal Chara travels to a peaceful True Pacifist timeline, those present have to find it in themselves to win and keep their happy ending. Meanwhile, Frisk wants nothing more than to SAVE the ones who don't have a happy ending of their own. An OC might eventually be involved in this. Inspired by the Swaptale webcomic. AU 001.

When Sans and Frisk slightly misuse the SWAP, they find themselves repeatedly hurtled into different timelines and universes, the first of which is the strikingly different world of Underswap! Stranded in a world where they never know what to expect, Sans and Frisk have to try to get a happy ending for both them and their new friends, in the first of my AU 001 spinoffs.

When the True Pacifist ending doesn't end well, Frisk's friends are given the choice of risking their lives to save them, or simply taking their happy ending and walking away. And in the end, thanks to ASRIEL, Frisk learns that they're never alone. Mostly a combat story with some feels. Pretty long, getting longer. Will be done 'fore long. AU 004.

The RED Team is separated and isolated. With three new members, they are lulled into a false sense of security. And, through it all, they never realize just how much danger they are in. First chapter is SUPER dialogue-heavy, pretty much no action. That will change soon.

Just a cute story I wrote for fun, with Sans, Toriel, Papyrus, Frisk, Gaster, and Flowey living together on the surface. One-shot. Rated K because I don't remember exactly what was in there, but nothing serious.

Sorry for waiting so long to upload. This one is another AU: 001 spinoff, but more of a comical one.

Who cares if the reasons for fighting are stupid, let's have a fight! When Hiccup and Toothless take on Pokemon's iconic human/dragon duo, who will come out on top? Rated T for some pretty nasty violence, and major character death. Yeah, one of the duos dies at the end. Just a warning.

It happens every time. Every single time. In the end, no matter what, ASRIEL is impossible to spare. But maybe, just maybe, with enough DETERMINATION, Frisk can change that. And he will never, NEVER give up. SPOILERS! And some pretty nasty violence. AU 003.

Of all the denizens of the world of Undertale, none are more mysterious than the enigmatic presence of W. D. Gaster. This story explores a possible explanation for his origin. But be careful. It's rude to read about someone who is watching. AU 002.
