Fatherly!Stoick.

Enter Midoriya Izuku, a young boy thought to be Quirkless who subconsciously controls the number one vigilante in Japan; an entity powerful enough to rival even the strongest villains. There's only one small, tiny problem: the entity thinks of him as a big brother. Good luck, Izuku-nii-chan!

The Omnitrix, a device that turns it wearer into one of many aliens: On one earth, this watch made Ben Tennyson one of the unique few humans with super human abilities. On this earth though, maybe it can help just make Izuku Midoriya feel normal and like he belongs among everyone who possessed what he hadn't been allowed. And maybe even send him on his way to achieving his dreams.
