Smallville Season Five Finale: All Is Lost; Kneel Before Zod

The fifth season of Smallville , which aired from 2005 to 2006, is widely considered the show's "darkest hour" as it transitions Clark Kent from teenage exploration into adult responsibility. This season is marked by the introduction of significant DC Comics lore, including the Fortress of Solitude , the villainous Brainiac (played by James Marsters), and the first appearances of future Justice League members Aquaman and Cyborg .
