Many episodes are centered on a specific character. Most of them only appear in this special episode or perhaps in one or two more episode(s). Others have recurring occurrences or even are part of the main cast, but are especially in the foreground in a specific episode.


Some of the episodes centered on a specific character follow a specific formula. Among these are:

  • Freak of the week: The character of the week has super-powers, in most cases achieved by contact with kryptonite. He threatens, hurts or kills people and is overcome in the end, usually by Clark Kent. This type of single episode characters was especially frequent in the first seasons of the show.
  • Villain of the week: The character of the week is not a meteor freak, but a malevolent human or alien who may have or not have specific powers. He threatens, hurts or kills people and is overcome in the end.
  • Hero of the week: The character of the week is a benevolent character with some specific powers or super-powers who gets into trouble and is helped by Clark. He eventually joins Clark and helps him overcoming some threat.

Other episodes centered on a specific character do not fit in a specific formula. The charakters of the week in these episodes may be for example normal human beings without specific abilities, or benevolent metahumans or aliens.

A character of such an episode may already have appeared in minor roles in previous episodes, but have a prominent role in a specific episode. Even one of the main characters may become a character of the week, developing a special characteristic in an episode, such as Clark when coming into contact with red kryptonite.
