Legion

The aftermath of Doomsday's attack on Chloe and Jimmy's wedding leaves Clark in shock, but before he can search for the kidnapped Chloe, an evil being, known as The Persuader, appears and attacks him. Rokk, Imra and Garth, also known as The Legion, step in from the future to help vanquish the Persuader and the group realizes Brainiac has taken over Chloe once again. Meanwhile, up at the Fortress, Chloe, as Brainiac, informs Davis he is Doomsday and was created to kill "the other Kryptonian" and destroy the world.
