The other is a Bizarro, a dark doppelgänger who shares Clark's DNA, but not his values. Only one of them can survive. The Superman saga grows even deeper and more powerful in an event-packed season that includes the arrival of Clark's cousin Kara/Supergirl. "Keep a low profile and master your powers," Clark says. But Kara has other ideas. Plus: Lana Lang might prefer Bizarro to the real deal. Lois Lane makes a career leap. Chloe Sullivan finds that balancing a meteor power with a personal life isn't easy. And Lex Luthor's power-lust has a new fixation – Kara. New characters and new complications. New secrets and lore. New thrills and special effects. Suit up for Season Seven!
