Ben was given the master control to defend earth from invasion, but Azmuth soon saw it was a losing battle. The omnitrix was sent to a separate dimension to keep it from the wrong hands. Now, Izuku Midoriya is the bearer of the watch with the master control still unlocked. Now he uses its powers to help as many people as he can but doesn't know of the main function, transformation.

When the destroyed Omnitrix falls into the ocean to repair itself, one boy is destined to be the world's greatest hero. On this planet and more!

Some worthy souls are chosen to carry the mantle of great heroes. Sometimes, this is destiny. Other times, it's all about being in the right universe, at the right time, chosen by the right watch.

This is a side-story that is connected to my actual story "Heroes Never Die; It's Hero Time" where Izuku has the Omnitrix. So reading the main story is necessary to understand this collection of Omakes/OVAs. I aim to post an Omake/OVA every Friday when I am unable to post a chapter for the main story. Full summary, explanation, and guid lines for suggestions are inside.

At a young age of 10, young Izuku Midoriya and his friends goes camping with their families for the summer vacation, until it went south really fast. Finding a alien watch with secrets hiden in it he must choose to use it wisely as a vigilante and being a target of a evil warlord that looks like a tentacle hentai monster. Now follow the origins of the greatest hero Izuku 10.

It's been four years since Ben Tennyson last put on the Omnitrix. During this period, his interest in heroics grew as he worked harder than ever to pursue it at U.A. High School. However, with the sudden disappearance of Grandpa Max, Ben is forced to don the watch once more, protecting the planet against any extraterrestrial threats all while attempting to pursue an education!

It started when an alien device did what it did. Izuku Midoriya found a strange device on the beach one night after training when the device jumps onto his wrist. It grains him abilities from beings from other worlds. Watch him as he and his friends go through their adventures on Earth and Space in: The Alien Hero: Deku 10

Ben Tennyson gets sent to the world of My Hero Academia. Where is a world full of heroes and not everyone can be a hero. He enrolled in U.A High the number one hero school in the world. Many challenges will be ahead of him. He have to Go BEYOND! PLUS ULTRA! BenxHarem.

An American exchange student has moved to Japan to reach his dream of becoming a hero. To reach this goal, he will enter the greatest hero academy the world has ever known: "U.A. High." He will reach his goal, no matter what stands in his way. Doesn't matter if they have tentacles, armor, or the power to destroy whatever they touch, they can't stop him from becoming a hero!

Bakugo Katsuki, the boy known as being the one who'll make it to U.A, gets knocked down a few pegs when he realizes that he isn't always going to be the strongest; by himself, that is. Midoriya Izuku, abandoned by all, used by all; all because of his quirk. Having no home and no hope, he meets the blonde. What starts off as a one-sided relationship soon blossoms to something more.

After getting in a fight with an old enemy Ben Tennyson wakes up in a world where everyone has superpower and no one seems to remember him, how will he cope with his new lot in life and how will he cope with everyone he knew living on without him.

When he was 10, Izuku Midoriya has found the alien watch known as the Omnitrix. Ever since then, he has used the watch to become a vigilante and to save people with a smile on his face. When his secret is revealed, his life and the world will never be the same. Cover image not mine. Cross posted on AO3.

After a grave defeat, Ben loses hope in being a hero but after some unexpected circumstances, the wielder of the Omnitrix is transported to a world filled to the brim with heroes. Having to adjust to not only a new country but also going to school to be a hero Ben has plenty of challenges ahead.

One would think that in a world where everyday people possess impossible abilities nothing would really be a surprise. Izuku Midoriya, who upon the age of four was diagnosed as quirkless, was denied of his dream of become a hero that can save everyone with a smile. But fate gives him a chance; allowing him access not to one but a universe of powers and abilities.

Earth as we know it today felt like they could expect anything. They had Heroes with powerful Quirks, technology that benefited them greatly and a society that wouldn't crumble to pieces easily. What's there to worry about? How about Villians hellbent on world domination, a few secret organizations and Aliens from Space? Lucky for the Earth it has it's own protectors just for them!

Anything can happen in the vast Omniverse. One universe can have a teenage hero with a device that allows him to shape shift, one universe can have the majority of the world population be born with powers, and one universe can have both of them

At the age of four, Izuku learned that people were not born equal. At the age of seven, he found a friend who believed in his dream despite everything. And at the age of ten, he finally got the chance to achieve that dream. But with the enemies from beyond the stars, can this kid really become what the universe needs? Only one way to find out.

Midoriya Izuku, also known as Deku. A powerless child in world of superpowers with the dream of becoming the greatest hero of all time. The Omnimatrix, also known as the Omnitrix. The most powerful device in the universe, capable of allowing it's user to walk a mile in the shoes of other lifeforms. Maybe it was fate that these two met. Or just coincidence. Anyway, it's HERO TIME!

It had now been 3 years since Ben took a chance at a normal life. However, history had a tendency to repeat and life had a tendency to be unfair. With the news of someone person putting in a good word for him at UA, Ben would once again don the Omnitrix and face the challenges ahead all the while having one question in mind: "Could he meet the legacy of that watch once again?"

Ben has not been a hero for 3 years... But circumstances force him to put on the Omnitrix again!

That summer when Ben first found and used the Omnitrix was a simple one. Find bad guy, go hero, beat bad guy, get away, repeat. Ben was on top of the world; in a world full of quirks, he had the coolest one of all. However, every action has a reaction, and Ben's vigilantism has landed him in trouble. Now at UA, Ben must prove himself a hero, or suffer the consequences.

Read “Traversing into the Omniverse” before reading this. Ben and his AI friend, Cirla, have found themselves in a world filled with heroes and villains. While trying to find a way to get back to their universe, they will face many challenges. Villains, gangs, corrupt officials, a few heroes, the law, and of course… school. Will Ben give it his all to be a Hero or a Vigilante?

I looked around and saw that there were not that many ben 10 x mha with ben having the omnitrix like there were only 27 out of 100 story with just ben and in 2 of then ben didn't have omnitrix. In this ben dies of old age at 110 and is reborn in mha world, and due to certain circumstances ben will have to be a hero again, ben will help the next gen of hero in his own wayEXPERIMENT

Austin has been ben's wing for being a hero, but then he sacrifice himself and now he is a world, filled with heroes and villans, how will Austin handle this? Austin harem with female Katsuki, izuku and shoto
