Izuku was weak and defenseless. He was in short, a whimp. He never did anything about this, of course. So he stayed that whimp. Now? He wasn't much of a wimp anymore. Not when he has the Omnitrix.

The world of heroes was dangerous. Too dangerous to throw someone like Midoriya Izuku into it, thought All Might. Robbed of his destiny without his knowledge, Izuku lives on unaware. Now, ten years later, the universe gives him another chance. In a world where Symbol of Peace has fallen, the Watchman will protect the world in his place.

If you told Izuku Midoriya he'd fall in love with a woman over twice his size, with four arms, four eyes, red skin, and a desire for combat, he would have laughed in your face.

Join Deku on his adventures as he sets out to be the world's #1 hero

In a world where 80% of the world have abilities known as quirks being part of the quirkless 20% is quite sad especially seeing as it means you can never become a hero. Yet even so our protagonist Izuki Midoryia still hopes that he can become a hero and one day when he has a fateful encounter with... A device known as the omnitrix that gives him abilities he could never dream of.

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-A what it means to be Heroes.

Some are destined to carry the mantle of heroes. Others, are forced into the role. And sometimes, all it takes is being in the right place, at the right time, and the conviction to seize the opportunity presented.

All Might encounters a villain wielding power beyond his imagination. Can he defeat Vilgax, the Conqueror of Worlds?

It started when an alien device did what it did, it stuck itself upon his wrist with secrets that it hid, now he's got a quirk he's no ordinary kid he's Izuku! So if you see him you'll be in for a big suprise, he'll turn into an alien before your eyes, he's slimey, creepy, fast and strong he's every shape and size he's Izuku! And armed with the Ultimatrix he'll save the day!

My first memory... is of being beaten. With a quirk I could've protected myself, but they are quite fickle things. Only women could unlock the quirk gene. So I made my own. Now I gotta prove just how powerful I really am. (Art by Promsien)
