The Gimmick Card, also known as the Trick Card, is a special friend card that appears in certain boss battles. It depicts a green Hidden Mickey. The card acts as a 0 card, but cannot be broken. Each Gimmick Card has a special effect that temporarily makes the boss more vulnerable to Sora or Riku's attacks. In practice it is quite similar to a Reaction Command.
- Guard Armor: The Guard Armor collapses into a pile and does not attack.
- Trickmaster: The table and chair reappear in the middle of the arena, allowing the Trickmaster's weaker head and chest to be attacked. In Re:Chain of Memories, Trickmaster is stunned as well.
- Parasite Cage: The rotating platforms are replaced with one large platform, and the stomach acid disappears.
- Darkside: A broken piece of wood flies in, allowing you to fly up to the Darkside's head for close-range attacks. In Re:Chain of Memories, several pillars of rock form a staircase to the Darkside's head.
- Jafar: All the floor panels rise to the highest level, allowing Iago to be more easily attacked.
- Oogie Boogie: The metal wall guarding Oogie Boogie drops into the floor. In Re:Chain of Memories, Oogie Boogie is stunned as well.
- Giant Ursula: Ursula's tentacles disappear, and she drops her head to the ground. In Re:Chain of Memories, Ursula is stunned as well.
- Dragon Maleficent: A pile of stone blocks fall from the ceiling, allowing her head to be more easily attacked. In Re:Chain of Memories, a floating platform appears that allows the player to reach Maleficent's head while also keeping them out of any flames on the ground.
