The Fusion Hero: Dekiru (Adopted)

Izuku was so excited when he manifested his Quirk. Being able to combine with objects to make himself stronger? So cool! However, what he didn't expect, what no one expected, was what would happen if he used his Quirk on people... (Or, What if Izuku's Quirk was the Fusion Ability from Dragonball Z/Steven Universe?)

[Since the Original Author hasn't updated it in 2 years, I thought I might continue his work, I also plan to add some new fusions, that he might not have considered for the stories] The original Author is OmegaInfinity if you want to see his original work.
