It's a simple summary. The MHA Heroes, Heroes-in-training, and the League of Villains. Were all brought into a casion by the spirit of temptation, named Poker. to have them watch a new universe with, bending of the elements, animals, and spirits. To see a universe that tells not just one Avatar but two Avatar and their own stories.

A waterbender in a strange land. Katara had heard that statement before, but nothing could prepare her for what she got herself into. If only there was a place for her to learn about this new world, and people to help her... oh wait, there is! cover art designed by MeyM Violet.

One-shot ATLA AU in MHA "...After that life-changing fieldtrip, BAM! Here you are!" "Toph... Please include that it was years before we had our son." "I can't see the problem, Zuko."

After thousands of years without an Avatar, Midoriya Izuku is finally reborn as the Avatar in the age of quirks. But after being gone for so long he can't just resume his duties like nothing ever happened. It will be up to him to restore the Avatar status to what it used to be, all the while combatting threats, mastering the elements, and having no idea how to handle a conversation

If Katsuki is going to be the Avatar, he's going to be the best one the world has seen. Even if the Fire Lord decides he wants to use him for a war he's starting and even if everyone else in the world doesn't trust Katsuki. He's just going to have to be a little patient. Even if he doesn't want to.

In which Himiko is adopted by the Iidas, Hitoshi is best friends with an amnesiac Dabi, Katsuki has magic powers, Shouto and Zuko bodyswap every Tuesday, and Denki is dEfInItELy nOT the UA traitor. Crossposted from my ao3!

Avatar Aang was killed with the other Air Nomads during the siege of the Fire Nation. The Avatar Cycle of Reincarnation has been broken. But Raava and the spirits have a way to save their world. Their hope now lies in the hands of a certain quirkless child, chosen by Avatar Wan himself, and gifted with the legendary White Flames of Heaven. Watch as Izuku fights to save the world!

Billions of light years away, a pair of eyes flutter open, the color of molten gold. She wakes up in a new dimension, full of unimaginable abilities she could only imagine in her past world. She can imagine the Spirits are laughing at her above. Why is she stuck in a child's body?

Azula; a villain in a past life but now a future hero?

Zuko was reborn to pro hero Endeavor and Azula was reborn to a quirk-less father and a mother with a low level quirk.

After a particularly bad day, Izuku decides he has nothing left to live for. Little does he know, a certain incarnation of the Avatar from a whole other dimension has bigger and better plans for him. A found family story. Todo/Deku. x-posted to ao3 & wattpad

Many asumed that being born blind would ruin their chance at being a hero, Izumi is out to prove them wrong. Now she And her punkrock freind just need to keep Pinky and BoomBoom man from destroying stuff.

Un Mundo sin un Pilar de Paz cae en Caos, un Mundo que solo valora el Poder es un Mundo de Corrupción, sepan o no, los "Héroes" no son Dioses Benevolentes, son Humanos Corruptibles, pero en el Momento más Oscuro del Mundo, una Luz Brilla, no una que Adquirió Experiencia, sino una Luz del Alma que Nace (Portada por GokuSannin9000) (M por Sangre, Harem y Lenguaje Fuerte, Bakugou)

Nine students of U.A.s class 1A are trapped in a world not their own and have to figure out how to get home. Toph hears about some firebenders displaying strange abilities and calls Zuko in to help. Sokka nearly breaks down when he hears about the other Avatar. It only goes downhill from there.

There use to be peace between the four nations, but now there is only chaos. Because of the attack by the fire nation, the balance of power has shifted, causing the spiritual world to be thrown into a state of chaos. The only one who can restore order back to the world is the avatar but even he may not be able to do it alone. The spirits seek the aid of heroes from other worlds.

A step to the side, in some other flow of time... Katsuki Bakugou meets Toph a little earlier, a little differently. (An AU of my crossover story, I'll Move Mountains)

Destiny has a way of bringing the right people together. Toph Beifong is born with an earth quirk. From a young age, she's discouraged from ever using it, until she meets an airbender named Inasa that tells her they could be heroes. (A crime drama, a coming of age, a redemption story, and an action adventure all in one, because I can't pick a genre)

Izuku meets a blind girl in his UA class named Toph. How can somebody who is blind become a hero? What is her quirk? What is her goal?

…Todoroki didn't quite know what to make of the small, loud, and possibly crazy girl named Toph. One-Shot. DISCLAIMER: I do not own Avatar the Last Airbender or My Hero Academia.

This Story takes place in during the Sports festival when Mineta and Denki try to convince Momo and Jiro to wear cheerleader outfits. The only difference is this time they fall into the World of Avatar were they meet Team Avatar and try to help them beat the fire lord but what will happen in their world because they left it.

The Fire Nation royal siblings are reborn into the Todoroki Family. How would things work out for the both of them as they eventually cross paths with former friends and enemies?

In time's past, it was common knowledge that once the Avatar entered your life, you could say goodbye to any sense of normality. Unfortunately, in this day and age, nobody got that memo. And boy, how much they needed it. AKA non-canon one-shots for my main story that I write when I have writers' block.

What is Todoroki Shouto? He is the crown prince, the heir of his father's Nation. He is an anomaly, the weapon of his father's ambition. What he is not, however, is the avatar. Todoroki Shouto is not someone—something— that is supposed to exist. [The story of how Todoroki Shouto encounters the Avatar, and love.] (TODODEKU AVATAR AU)

Toph Beifong has had enough sheltering and pampering for several lifetimes and has had enough. With the help of her best friend Yaoyorozu and a weird short man (who claims to be an animal?), she is determined to become the greatest blind hero in the world. And don't you dunderheads ever forget it! (Coverart commission by @LunLucyArt, check her out on Instagram!)
