OP Y/n 10 x FEM One Punch Man (harem)

The world have heroes, villains and monsters but they all are female and they have some power but not male can be heroes because people think they are weak and useless?

But one young man can change the world and he name is Y/n and he is true hero of the world but no one can stop him. He will prove himself to be a hero. He will protect the people from danger and he will defeat to powerful enemies.

Also some females hero, villains or monsters want him to their mate, husband or king.

He can transform into all aliens and he can transform all aliens into Ultimatrix aliens and super Ultimatrix aliens. (I will try make what they look like)

He will get massive harem!

And he will get new aliens forms!
