Organization XIII's Replica Data

Organization XIII Data Replicas are optional bosses found in Kingdom Hearts II: Final Mix+, found in the Cavern of Remembrance. Once Sora, Donald Duck, and Goofy reached the Garden of Assemblage, they could access a computer that would reveal doors that correspond to each Organization XIII member that they defeated. If Sora accepts the challenge from a door, it would warp Sora and his friends to wherever they fought that Organization member, and a data replica of that member would appear and fight them. (for example, if Sora accepted the challenge from the door with a sitar on it, they would be warped to Radiant Garden and a data replica of Demyx would appear and fight them.)

These battles are extremely hard, with each data replica having all health bars maxed out.

Axel and Xemnas's battles are only available after beating the game. Xemnas's battle consists of two battles: the one at Memory's Skyscraper, and the final battle in which Riku helps you.

Also, the order of the doors is the same order in which the members sit in their thrones.

Furthermore, the battles here are made significantly harder than the normal game encounters (i.e. battles in the storyline and the Absent Silhouette battles), such as their most powerful moves are used more frequently. Also, some of the battles have been tweaked for the said increase in difficulty. For example, the Xigbar battle now lacks the short pauses that leave him wide open (signified by his line "Arms, reload") and in the Demyx bout, Demyx only summons Demyx-shaped water forms, meaning the reaction command used to grab a note-shaped water form to destroy even more forms is now gone.
