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

Izuku Midoriya is about to give up on his dreams of heroism when a teenager clad in a green jacket and a man claiming to be a professor break into his room in broad daylight. Benjamin Tennyson and Professor Paradox have travelled to the My Hero universe in order to find a worthy successor to wield the Omnitrix once Ben passes... and he firmly believes Izuku is worthy to inherit it.

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.

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.

His goal in life was to be a hero and along with the gifts that he has gained, he will be one. Mini extra crossovers with the story. Izuku x Hearm

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.

Being a hero is something Ben Tennyson has been for quite some time, but he never thought he'd see a world where it was commercialized. After a chance meaning with one of these 'Pro-Heroes', Ben agrees to go through a school to become a hero. With no way home and three of his most dangerous foes on the loose, Ben must learn from these heroes to help him in the long run.

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.

In an alternate world where Ben defeats the Diagon but is then blown out of his timeline and into the MHA timeline, Paradox has given him some advice and something new as well but now Ben is on his own in a strange world where heroes don't need secret identities. Rated T cause Bakugo

Ben,Gwen, Kevin and Rook were originally on the verge of a road trip to enjoy a well deserved rest. Their plans got interrupted as they were contacted by the principal of U.A High,who requested their help to teach Class 1-A what it means to be heroes.

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?"

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. (On hold)

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.

I've loved Ben 10 since I was a kid so I thought this would make a good crossover, plus MHA is a pretty cool show in it's own right. I hope others enjoy my story.

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!
