Organization XIII's Replica Data
The Organization XIII: Replica Data (XIII機関：再現データ XIII Kikan: Saigen Dēta) are optional bosses found in Kingdom Hearts II Final Mix at the Garden of Assemblage. Once Sora, Donald Duck, and Goofy reach the Garden of Assemblage, they can access a computer that reveals portals corresponding to each defeated Organization member. The portals are labeled with their member's signature weapon and are arranged in the same manner as the thrones at Where Nothing Gathers. When used, a portal will transport Sora and his friends to a digital copy of the arena in which the member was defeated, where the Replica Data will materialize and attack Sora. In order for a portal to be operational, the Organization member or Absent Silhouette must have been previously defeated; however, the portals for the members fought at The World That Never Was are not operational unless the save file has been cleared.
These battles are extremely difficult versions of the earlier battles, with much more HP, speed, and stronger attacks, but repeatedly conquering the battles is a fun and efficient way to farm Stat-Boosting items and Lost Illusions.

Trivia
- The Roxas data replica is the only replica to be hooded while fighting.
- Xion is the only Organization member without a Data Battle. This is not surprising, as she also never received a throne, a tombstone, or a title. But it is also because Xion hadn't been introduced in the series yet.
- Although Lexaeus, Marluxia, and Larxene are all fought in Castle Oblivion, their battles are all in different areas. Lexaeus is fought in the castle's basement, which has a different floor design and slightly different background from the upper floor, where Larxene's battle takes place, while Marluxia is fought in his own chamber, which is much larger than the other areas.
