Clow Cards arc[]

In Episode 8 of the anime, The Thunder is witnessed periodically going on rampages throughout Tomoeda before it's finally sealed using The Shadow. It is the first card that Syaoran and Sakura capture together.

In the manga (volume 2), Sakura captures Thunder alone. She then uses it to capture The Shadow using the light generated by Thunder to disperse the captured shadows.

In the anime, Sakura use The Thunder along with Syaoran's lightning magic to try to capture The Twin.

Sakura Cards arc[]

In Episode 67 of the anime/Volume 10 (Chapter 42) of the manga, Sakura transforms Thunder into a Sakura Card when she used Thunder to defeat a magical horse that was attacking her.

Clear Cards arc[]

Thunder, like the other Sakura Cards, turned "clear" (blank) and are rendered powerless.

It is later revealed that the Cards were with Syaoran in order to protect Sakura magical powers had grown enormously and that this could be detrimental to her. With the collaboration of the cards, who also wish to protect Sakura, Syaoran is able to rewrite the contract of the cards, replacing Sakura’s name on them with his name and allowing him to utilize their powers, which essentially makes him the new master of the cards.

When the Cards pass under Syaoran's possession, they receive his Moon powers and appeared the Crescent Moon symbol in their forms. The cards moved by their love for Sakura and their desire to protect her. Left with Syaoran through a spell arranged by his mother to prevent Sakura's powers from growing further while creating the Clear Cards; but doing so is extremely exhausting for him and takes longer than desired. However, when the world is rewritten by a taboo magic, the cards return to Sakura's possession as if they had never left.



  • The card is based on Raijū, a creature from Japanese mythology.
  • In the anime, the Shadow is used to capture the Thunder card, whereas in the manga, Thunder was used to capture the Shadow, making it seem that the two have the power to cancel each other out.
  • The kanji at the top of the card: 雷, (Pronounced 'Kaminari') means 'thunder' or 'lightning bolt' in Japanese.
