This is the story of a self-insert who, after struggling with sickness, dies and reincarnates into the My Hero Academia universe. After a few years of growing up, he gains his quirk, but this also makes him immortal and stuck as a child. Follow the story of Leo as he travels through multiple worlds. Disclaimer: Drawbacks will be mitigated as the story progresses.

Hero Society is flawed, and the Symbol of Peace is declining. With threats from all over the globe and even the stars arriving to stake their claim, it's time for the next generation of Heroes to stand up and become paragons of peace. Now... if only I could keep my idiot friend from getting himself killed first. SI-OC. MHA/Ben 10/X-Over.

Eight years ago, a massive explosion of light and ice levelled Moscow and killed over a million people. Five Years ago, All Might nearly perished in a fight with his greatest enemy. Yesterday, a freak storm hit Japan. Something split the heavenly skies above and time was wounded. Mainly (Warframe X MHA) & Others

After Izuku and his friends followed the villain through a portal, he and his friends wind up on an adventure through multiple universes and meeting those who have their own issues with the denizens. (Crossover between My Hero Academia and any games/horror/supernatural/action movies/books/anime shows that I include.)

A year after Gramorr's defeat, Praxina and Banes went to another dimension to gather allies to help her destroy Iris' adopted home World and recreate Banes' crystal monster army. Iris, Talia, Auriana, Lyna, Carissa, Izira, and Amaru(with four certain boys accidentally becoming stowaways)went to that dimension to find the next generation of Crystalizer Rangers to stop them.

Izuku is orphaned and alone after his mother dies due to a villain attack. He makes a wish for a loving family on his birthday, and he gets his wish. Only his new family isn't quite what he was expecting...

When Izuku asked All Might the most important question of his life... the man dashed his hopes with a single word: No. Now, after a camping trip with his mother, an asteroid changes his life forever with it's contents: a watch that transforms him into 'waifus.' This is a more comedic, but also darker take on MHA's story. MultiCross (because 'waifus') and highly cannon divergent.

Seeing a decline in true heroism and over reliance on the Symbol of Peace, along with not wanting history to repeat itself, Nedzu decides to give All Might his own class. A class filled with caring and heroic youth all disadvantaged in some way, who will become the NEW beacons of peace, justice and heroism. Crossovers abound!

Class 1-A has grown a lot together and become something of a family. A wild, crazy family. But what about their actual families? What will they think of the family members their classmates never told them about? Massive Crossover AU. Characters may be OOC. Rated M for language and possible explicit content in the future.

After being diagnosed as Quirkless, Izuku had been neglected by his mother & 'father' & bullied by his 'sister ' along with the Bakugo Twins. Until on his 5th Birthday, his real father came & received his custody. After moving in with his father & new mothers, Izuku continues his path to fulfill his dream of becoming a hero

In other words, a series of one-shots, trailers, and plot bunnies that never fail to escape my mind...I may or may not continue to raise said bunnies. You decide what you would like to see. Note: Will have a lot of MHA stuff. But the 1st chapter is something else.

We all know the story of Izuku Midoriya from My Hero Academia and Conan Edogawa aka Kudo Shinichi from Detective Conan Case Closed, but, what happens when their worlds along with others are mysteriously put together one day? Are all people involved well? Does Izuku have a quirk and Kudo not a child? Or did the both of the main protagonist's paths diverge into a whole new adventure?

A spin-off of KiddoIsTheBest’s MHA Reacts: Marvel Cinematic Universe. Takes place between Phases 1 and 2. When Kiddo agrees to work with mysterious unknown extradimensional entities known as “The Superiors”, they send an employee of theirs to act as a host while Kiddo is away. The Executive is assigned to the case(with some help from his fellow coworkers). Things get weird fast.

Amber's an orphan with an incredible quirk that only she knows the name of & it's called Creational Drawer. Izuku was told that he was quirkless, but Amber found proof that Izuku isn't quirkless. Izuku's quirk is similar to her own quirk called Doodle Creator. Can Amber's first creation Eclipsea, bring them both to safety from AFO. Who is Izuku's father. IzukuxOC opIzuku opOC

Collab with Devil Dragon Stand Knight. For all the bright and shiny hope the hero world shows, there will always be darkness. Within that darkness, there can be light, if given the chance. These students of UA will work to prove they can be heroes, if not for the world than for each other. BRUTAL VIOLENCE! Read and review, would ye kindly? CHAPTERS 3-6 REVAMPED!

After getting strange powers after singing Sweet Caroline in the Void, Dōka is reborn in the world of Quirks with the power of Sex Magic by his side...unfortunately, he also has a Heavenly Restriction that makes him weaker than paper. Watch out world, the weakest Eromancer is here to rise to the top! [Gamer!] [Harem] [SI/OC] [Self Insert]

Based on "The Many Dates of Danny Fenton" by Flower Princess 11, I wanted to try my hand at this

When Izuku decide to visit an shrine that he come across, he don't expect to encounter an deity who claim that he will have one hundred soulmates and if he reject anyone, they will die from broken heart. Now he have to meet one hundred soulmates who really, really, really, really, really love him and deal with it!

My Hero Academia 7-Way Crossover Idea

Mival Weaver died and got four, no, striped that, three wishes. What does he wish for? Worlds: MHA

The new influx of deities within the Doomsday Theater has started to open up a hole within the very fabric of reality itself, allowing a mysterious enigma to slip through the cracks and gain complete control over the events to come. (Spin off to KiddoistheBest's MHA Reacts: Marvel Cinematic Universe)

A spin-off of Kiddo's: MHA Reacts to: The Marvel Cinematic Universe. Takes place between Phase 1 and 2. Kiddo is pestered by a group of entities calling themselves the "Alliance". So much so that he gives up and lets them host.

A collection of short stories that take place within the Sancutary universe, all canon unless otherwise stated. Rated M to be safe and open to suggestions and co-writing. Be ready for tears, jeers and cheers. Read and review, would ye kindly?

We're sure we were meant for this since the war between good and evil never ends. This conflict exists in all worlds, and it is our destiny to take part in it, either as a villain or a hero in this never ending conflict. We have the power to rewrite our fate and our history. We are the warriors who have learned to embrace suffering; although coming from many words, we are all Deku.

When three reality jumping teens and an android end up opening the world of heroes to world of the multiverse, things can never normal. Not like normal was ever the option. Now martial artists, ninjas, aliens, and Pokemon trainers are all over the place. Maybe, just maybe, Class 1-A can pick up some new skills from their new student teachers. Rated M for Madcap.
