You'd think that in a world filled with Super Heroes, aliens would be a normal thing. Heck the romanticized version of heroes from old comics has always been that of alien heroes falling to Earth as babies. But not in this Quirk Based Society. Ben Tennyson, aspiring hero student at UA Hero Academy and wielder of one of the most powerful devices in the Galaxy, The Omnitrix, now has to deal with the fact that the nature of his power isn't a secret anymore. His adopted family plagued by reporters, he can't even go on a proper date with Kyoka Jiro. And with tensions on trusting UA's public relations already at a low point thanks to the USJ events and the League of Villains, Not to mention the secret organization known as the Plumbers revealing their hand, things are set to come crumbling down on the Hero in Training. But Ben's got several things on his side. His classmates, his girl friend, All Might, a bunch of super powered alien forms, and witty sarcasm.

'Quirkless' 'Pathetic' 'Useless' 'A Deku' Those are the words Izuku Midoriya heard in his harsh life. 200 years ago, superpowers appeared into the world called "Quirks" and 80% of the population of the World have them, while the 20% are people born without it are called "Quirkless", and Izuku Midoriya is one them. All he just wanted to is to become a Hero. He wish to have a Quirk to save others... and of course the Universe answered his prayers. A chance of a lifetime; the power to allow him access not to one, but a Universe of powers and abilities.....from another Dimension. The Omnimatrix. Join Izuku Midoriya and his gang of friends as they journey together to save the day, take names and kick Villain ass, and become the greatest Heroes of all time. "IT'S HERO TIME! PLUS ULTRA!"
