Eyecatch cards are cards with different information of the various characters and objects that appear in the anime series Sonic X.

- Cream's eyecatch cards have the same artwork that is used in Sonic Channel.
- Charmy Bee is the only member of the Chaotix to have his own eyecatch card.
- The Chao and Chaotix are the only cards that show more than one character.
- "Countdown to Chaos" is the only episode to feature only one eyecatch card.
