There are two Clark Kents. One is the young man whose life in a tiny Kansas town sets him on destiny's path. The other is Bizarro who shares Clark's DNA but not his values. Only one of them can survive. This season includes the arrival of Clark's cousin Kara/Supergirl. Plus, Lana Lang might prefer Bizarro to the real deal and Lois Lane makes a career leap. Chloe Sullivan finds that balancing a meteor power with a personal life isn't easy. Lex Luthor's power-lust has a new fixation - Kara.
