Written by comic book scribe Geoff Johns, “Legion,” as many might already know, introduces the Legion of Superheroes to Smallville.  Composed of Cosmic Boy/Rokk (Ryan Kennedy), Saturn Girl/Imra (Alexz Johnson) and Lighning Lad/Garth (Calum Worthy), they’ve flown in from the future to help Clark defeat a notorious villain.  Sources continue to reveal that the long-time LSH enemy in question is actually the Persuader.

The CW has also released its official description of the episode, mentioning that Chloe in her Braniac persona tells Davis that he is Doomsday.  Also, he was created to kill “the other Kryptonian” and destroy the world.  This could be the start of what TV Guide hinted at, wherein a Clark/Doomsday showdown will take place.
