The hero "From the Stars."

A villain warps away Izuku.
He has been labeled as missing for 10 years, but his story does not end this. No, it begins anew in another realm where he spends 500 years only to return and rise up once more 10 years later in his home world.

But this is a very different young man than the boy that was sent away.
He is mighty, mystical, talented, and capable. What caused him to change so much?
