Legendary

Imagine if you were the one who destroys humanity. Legendary tells the story of Charles Deckard, an art thief who is duped into stealing Pandora's Box. When he opens the box, he releases hordes of beasts thought to be fictional into an unprepared modern world. A full-scale war between man and myth begins, and it is quickly complicated by the actions of powerful secret societies. Deckard unwittingly becomes the only person capable of saving civilization from being destroyed.
