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

This is a side-story that is connected to my actual story "Heroes Never Die; It's Hero Time." So reading the main story is necessary to understand this collection of Omakes and OVAs. I will post these small side chapters when I am unable to post a chapter for the main story. Full summary, explanation, and guid lines for suggestions are inside.

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?"

When an average joe gets dropped into a world manipulated by a seemingly omnipotent being, they quickly find their understanding of both sides of the setting tested while coming to terms with their unique situation. Will they rise above their trials and become a hero? Maybe. Should this be taken wholly seriously? Probably not. Warning: Contains OC-SI, Swearing, and violence.

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!

Neito Monoma would tell his friends and classmates that in the world of Quirks and Pro Heroes, he has accepted his role as a side character. In the realm of aliens and the supernatural, however, Neito is gifted an otherworldly watch that thrusts him into the center spotlight. Whether as the Phantom Thief or the Wielder of the Omnitrix, Neito vows to be an exemplary hero.

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.

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.

Where a young Quirkless boy is given friends, a construction company in the Kansai region does not fail, and a teenager is granted a certain green watch. Even in a world where superpowers are commonplace and the laws of physics are violated by toddlers, destiny can be shifted by the smallest of changes. (REWRITTEN VERSION!)

Izuku Midoriya comes in contact with a mysterious watch known as the Omnitrix and his life is forever changed. Now armed with ten new superpowers, Izuku Midoriya is ready to face the villains of his world and become the hero of his dreams. He's slimy, creepy, fast, and strong. He's every shape and size. He's Deku 10!

The Omnitrix is the source of many rumors and conflicts, with the power to become anyone. The worst of the worst sought it for conquest and power, the best of the best wanted it to keep peace. But what happens when the tool falls into the hands of a student on Earth? One who struggles with grades and control over his quirk? Well, you get Denki Kaminari.

After Ben gets THE Omnitrix, disaster struck. An experiment a few villains did goes wrong and sucks them and an unwary Ben Tennyson into Musutafu, Japan. Now alone in a word filled with Quirks, Ben will have to start a new life from scratch. Rated T because of Mineta and his questionable behaviour.

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.

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.

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.

Ben Tennyson was just a some kind of a Underground hero, who finally've got a chance to stabilize his life. But guess what, this one mission in Japan decided to butt it's way into his life and say "No, no, no" to his plans. What was he supposed to do again? I suck at descriptions, read to find out!

One fateful night, Izuku Midoriya wishes on a shooting star to become a hero. And then he finds an alien wristwatch that let's him become 10. (And maybe more.) With villains popping up left and right, and an alien warlord seeking the power Izuku now holds, there's only one thing to do. "IT'S HERO TIME!"

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.

Everyone knows Ben Tennyson, hero of heroes, the one who defeated and saved the High Breed and recently the boy who finally got rid of Vilgax. Conquerer of 10 worlds, now the bearer of the Ultimatrix. Then after saving a woman from drowning, a super heroine named Midnight, ben ends up biting off a lot more than he expected as more pop up into his life. Lets hope he can survive.

Ben 10 but BNHA style

while training to get into UA Izuku came across the omnitrix and his world gotten a lot bigger and now he has to master both the watch and one for all to become a hero like his idol All might but can he make the cut? find out. Izuku/harem mixing with some DC characters and a few other surprises and a bit dark toned.

Ben Tennyson was severely injured in his fight with the alien warlord Vilgax, he was injured to the point where the omnitrix was unable to save him. With no other option, Azmuth does something to cause the omnitrix to merge with Ben. Frozen in stasis, Ben wakes up in the 23rd century were people are now born with the potential for super powers. How will Ben adapt to this new era

A chance of a vacation from his universal renown has landed Ben in the world of My Hero Academia and into a crash landing into Izuku Midoriya's life! What will this mean for Izuku's story? What will change? What will stay the same? There's only one way to find out!

When a powerful device called the Omnitrix clamps itself onto Izuku midoryia, he must learn to use his powers to help him on his journey of becoming a hero. Will he be able to make it to U.A, or will he fall to an evil warlord bent on universal conquest?

There are an infinite number of ways to tell a story, most of them play out in the Omniverse. Fate is a cruel mistress, and sometimes the 'All' in 'One-For-All' does not include Izuku Midoriya. Actions have consequences, and some things are better off, while others are worse... much worse...
