- Clark is shown using several of his super powers: super leaps (in Season 4's Lucy), super speed (in Season 7's Apocalypse and in Season 4's Commencement) and heat vision (in Season 7's Descent).
- In addition to Clark, two other characters are shown using superpowers. Bizarro is shown using two of his superpowers: super hearing and flight/super-leaps, while Kal-El is shown flying. This means that Tom Welling appears in three of his major roles in the series: as Clark Kent, Bizarro, and as Kal-El.
- Bizarro appears twice in the opening credits: once while listening for a bomb about to kill Chloe, and again while flying/jumping up the stairs to rescue her. This is the most appearances of any non-main character in the opening credits.
- Clark is shown twice de-powered: once in Season 7's Blue, and again in Season 8's Odyssey.
- Davis Bloome features the least in the credits whereas the other new character Tess Mercer reappears several times throughout the credits.
- Allison Mack is moved from 4th up to 2nd billing, Erica Durance from 5th to 3rd billing, and Aaron Ashmore from 6th to 4th billing
