Data Xemnas (DE:coded Boss)

In Kingdom Hearts DE:coded, a Data Xemnas appears in the Data World That Never Was, Maleficent and Pete's tamperings with Jiminy's Journal granting him the use of two alternate boss forms, the King and the Kentauros.

Trivia

 * Both the King and Kentauros were to appear in Kingdom Hearts II as Xemnas's final forms. While concept art exists, showing them to have been comprised out of buildings from the Dark City, they both were replaced by Xemnas's Dragon, Armored Controller, and Final forms.
