With Michael Rosenbaum and Kristin Kreuk gone from the regular cast this season, there's plenty of room for new faces. Davis Bloome, a Metropolis bartender will become part of the story and ultimately become Doomsday (who in the comics killed Superman). Another villian, Tess, will arrive on the scene when she takes control of Lex Luthor's estate in his absence. She's a woman of many talents, including an otherwordly power of persuasion that works on everyone, including Clark. Justin Hartley will also return for 12 episodes as Oliver Queen, aka Green Arrow.
