After Sora and his friends find proof of Alice's innocence, the Cards attack them by order of the Queen, who doesn't believe she is innocent. When Alice is kidnapped, the Queen orders the Cards to search everywhere for her, but they don't succeed, since Alice is no longer in Wonderland.

Along with Alice, the Queen of Hearts, and the other inhabitants of Wonderland, the Card Soldiers appear in Disney's Alice in Wonderland. A larger amount of cards appear in the movie than in the game. The playing cards make up a very large army for the Queen and King.
