Instead of superheroes, Smallville's latest casting comes from the world of super models. In this season's third episode (airing Oct. 11), Eva Marcille Pigford - winner of the third cycle of America's Next Top Model - will guest-star as Tyler, a villainous beauty queen with a superpower. Pigford's alter ego shows up for the 100th annual Harvest Festival, where her competition in the Miss Sweet Corn Pageant (!) will include new cast member Kara, aka Supergirl (played by Laura Vandervoort).

In an homage to Tyra Banks, the episode is titled "Fierce." - Reporting by Rich Sands
