Gemstones AU. Instead of Gunhead, Uraraka is offered an internship with Ben 10,000. From there, she starts the path of becoming a shapeshifting alien hero.

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.

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.

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

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.

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!

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.

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.

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!

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.

Will Ben give it his all to be a Hero or a Vigilante?

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.

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
