RWBY x Destiny (Shattered Light)

In a dark future, from another timeline the city, the traveler and humanity was destroyed. It wasn't destroyed minion of darkness, only by a Guardian who lost his path, it was a evil version of Kai. He destroyed everything his allies, teachers, and family. He conquer other planets, but he wasn't satisfied until he discover the multiverse. He sees different version of Guardians and the city, and other realties, but the only he was interested is the one of the center of the multiverse, a version of himself with a girl with red cloak.

''No Guardian is safe"
