- Clark develops one new super power this year: X-ray vision, ("X-Ray").
- Clark uses his existing powers as early as the first episode: super speed, super strength and invulnerability.
- The exceptions to the freak of the week format include "Rogue", "Zero", "Nicodemus", "Stray", "Obscura" and "Tempest", although the Nicodemus flower in "Nicodemus" may count for a plant version of a meteor freak, and "Obscura" involves friendly people infected with meteor rocks, meaning that there are only three episodes that does not involve kryptonite as an important element.
- The Young Adult Novel See No Evil was originally planned as an episode for the season, but eventually changed into the story for "Shimmer".
- "Flight" was another young adult novel conceived for season one, but dismissed since the writer wasn't sure how they could do the special effects for flying.
- There are no villains in the main cast in Season One.
