World Cards

World Cards (ワールドカード) are a type of Card in Kingdom Hearts Chain of Memories and Kingdom Hearts coded.

In Kingdom Hearts Chain of Memories, World Cards are light blue, with an image of a World on it. One World Card can be used on each floor to transform it into a certain World. Unlike other Cards, World Cards are obtained from other characters during events.

In Kingdom Hearts Re:Chain of Memories, the Destiny Islands World Card shows its World image from Kingdom Hearts II in cutscenes, despite the Card itself using the image from Kingdom Hearts.

In Kingdom Hearts coded, World Cards allow Data-Sora to change the rooms of the digital Castle Oblivion into representations of the worlds he has visited.

Development
Deep Jungle appears in early screenshots of Kingdom Hearts Chain of Memories, but was removed as the estate of Edgar Rice Burroughs didn't allow Disney and Square Enix to reuse the story.

Kingdom Hearts Chain of Memories
Upon entering Castle Oblivion, Sora, Donald, and Goofy encounter Marluxia, who samples Sora's memories and gives him a card for Traverse Town. They encounter the figure again once they reach the 1F Exit Hall, but when Axel appears, the figure gives him a number of cards and leaves him to test Sora. After defeating Axel, Sora receives the cards for Agrabah, Olympus Coliseum, Wonderland, Monstro and Halloween Town. As Axel and Larxene observe the group reach the sixth floor, Larxene declares it to be her turn to face Sora, and Axel gives her more cards. After she is defeated in the 6F Exit Hall, she tauntingly gives Sora the cards for Atlantica, Neverland, Hollow Bastion, and the 100 Acre Wood.

In the meantime, Riku awakens in a strange place, where DiZ offers a way out by presenting him with the card to Hollow Bastion. When Riku takes hold of it, the card takes him to the B12F Entrance Hall. After leaving the floor, Riku is confronted by and fights Ansem, Seeker of Darkness, who gives him cards for Traverse Town, Agrabah, Monstro, and Neverland, as well as providing Riku with the use of Dark Mode. After Riku reaches the B7F Entrance Hall, Ansem appears again, and he gives Riku the cards to Olympus Coliseum, Wonderland, Halloween Town and Atlantica, challenging him to continue resisting the darkness.

When Vexen brings the Riku Replica to the upper floors, Axel gives him the Destiny Islands card, which Naminé uses to change the replica's memories to think he is the real Riku. She also transforms the card into the form of a good luck charm.

Vexen gives Sora the Twilight Town card when he is defeated in the 10F Exit Hall, saying he made it from the memories locked in the other side of Sora's heart.

After fighting the Riku Replica for the third time, in the 11F Exit Hall, the replica drops his good luck charm, which transforms back into the Destiny Islands card in Sora's hand.

When Riku reaches the B3F Entrance Hall, Zexion gives him the Destiny Islands card. Mickey Mouse finally catches up to Riku in the B2F Entrance Hall, and he gives him the Twilight Town card, saying it led him from the Realm of Darkness to where Riku was. At the Exit Hall, DiZ gives Riku a Castle Oblivion card to draw out Ansem from within his heart.

Kingdom Hearts coded
Upon reaching Castle Oblivion, Data-Sora encounters Data-Roxas, who gives him the Destiny Islands card and tells him to use it to find the "truth that sleeps". After Sora clears the room, the figure taunts him about his lost memories and gives him the cards for Traverse Town, Wonderland, Olympus Coliseum, Agrabah and Hollow Bastion.

After Data-Sora has used all of the cards, the figure confronts him again and engages him in battle. After Sora defeats him and accepts the burden of hurt into his heart, the figure gives him the Castle Oblivion card, which leads him to Data-Naminé's room.
