(Bnha X Male OC) Americas Final Defense

People around the world started to manifest quirks except for one place, the United States of America.
Other nations started to see the United States as weak, there allies broke ties with them, and other nations wanted to conquer there land and there rescources, so they started a war with the United States and the United States lost.
But right when it felt like hope was gone two twins were born with powerful quirks, making them the first two people to ever have a quirk in America, and have two of the most powerful quirks in the world, the quirk of life and death.
