He died. But they forced him to come back. He was a human, but as a result of a monstrous experiment he became a monster in human form. He remembers nothing, yet fate keeps tossing him fragments of the past. He wants peace, but they torture him and make him fight. And he will take revenge. First and last of his kind. He won’t let any others like him appear. He will destroy those who created him. Because he is—Zero.
