Ben 10 x My Hero Academia

It has been five years since Ben 10 put off his omnitrix and stop his hero work in America. Everything was normal until one day when his grandfather Max got missing not without leaving a message. Ben 10 must choose whether to put on the omnitrix again and return to his hero life or stay normal. He must travel to Japan along with cousin Gwen to find out any leads to their Grandfather Max.

Note: Basically Quirks are found mostly in Japan and all other countries. But in this AU 10% of quirkless people of total Earth's population are found in America including Ben 10.

Crossover between Ben 10 and My Hero Academia. It starts from Ben 10:AF timeline and Izuku UA exams.
