Datascape

The Data Worlds (データの世界, Dēta no Sekai) were created when King Mickey digitized the contents of Jiminy's Journal in order to solve the mysterious messages that appeared in it. They are, for the most part, the same as their real counterparts, which Sora visited during the course of Kingdom Hearts. These replicas of worlds appear in Kingdom Hearts coded.

Episode 1
In Episode 1, the Data World was created when King Mickey digitized the Jiminy Journal to find out the secret about its new, mysterious message. When they are about to digitize the whole content, Bug Blocks appear in the Data World. King Mickey decides to create a Data Sora to eliminate the Bug Blocks. King Mickey, Jiminy, Donald, and Goofy watched the computer to monitor what was happening in the Data World.

Episode 4
In Episode 4, it is revealed that The King, Donald, Goofy, and Jiminy weren't in the real world any longer. Jiminy's Journal, having taken the form of Riku, took them into the Data World, which is why Heartless are present and the doors have been locked. Chip and Dale are in the real world trying to communicate with them, but are unsuccessful.

Episode 5
In Episode 5, Pete is revealed to be from the real world to interfere with whatever is going on in the data world. He then leaves the Data Olympus Coliseum, and the Data Sora follows him to the Data Agrabah.

Episode 6
In Episode 6, Mickey and Jiminy's Journal arrive in a new area of the Data World and dispatch the Shadows. Pete explained that when he was in Disney Castle to spy on King Mickey and the others, he saw the bright light that brought him into the Data World. Maleficent also appears in the Data World, who has made it her goal to rule the Data World.
