Replica Xehanort

The Replica Xehanorts are a set of twelve replicas created from the members of the real Organization XIII.

Kingdom Hearts III
On Master Xehanort's orders, Vexen created replicas to house hearts from the past and perfect copies of the real Organization, save Master Xehanort himself, to serve as additional reserve members.

During the second Keyblade War, Xemnas cryptically forewarned Sora of the replicas when he kidnapped Kairi; just as the Seven Guardians of Light had allies to take their places, the real Organization XIII still had more "darknesses" in reserve.

The twelve Replica Xehanorts appear in Scala ad Caelum, having been summoned by Master Xehanort. Initially appearing as phantoms of the original Xehanort, they soon take on a new form, wearing purple cloaks with silver masks hiding their faces. Due to their numbers, Sora, Donald, and Goofy misidentify them as remnants of the defeated Organization. The twelve replicas vanish, hiding in four smaller groups for surprise attacks. After being defeated by the trio, the replicas are absorbed by Master Xehanort to increase his powers, transforming him into Armored Xehanort.

After Sora manages to break his armor, Master Xehanort releases the Replica Xehanorts to battle the Guardians of Light who are at the Keyblade Graveyard. The Replicas manage to trap Lea, Roxas, Xion, Aqua, Terra, Ventus, and Riku in a dark void, leaving a weakened Mickey to fight them. With future Sora lending aid, Mickey temporarily disperses the Replicas and pull everyone out of the darkness.

Following Master Xehanort's desire to keep the pure light away from the Guardians, Replicas return once more, this time forming into a copy of Armored Xehanort. The Armored Xehanort faces off with Sora, who restored Kairi with the power of waking. Sora and Kairi fight Armored Xehanort and he is finished off by a combined attack from all of the Guardians of Light.

Fighting style
The Replica Xehanorts each use the abilities and signature weapons of one of the members of the real Organization XIII, aside from Master Xehanort himself. The replica of Ansem also does not wield a weapon, rather relying on Ansem's dark powers. All the weapons have a blue glow that obscures most of their features. While they appear in groups of three-to-four, the replicas tend to attack one at a time, while the others hang back. Should one replica be countered or attacked, another will use the opportunity to attack Sora. Each group has a replica with long distance attacks, be it Fair Game, Foudre, Sharpshooter or Ansem's dark powers. Marluxia's replica can also make surprise attacks from behind, dealing damage with a horizontal spinning scythe attack. In order to avoid Sora, they rely on teleportation and quick attacks, often "tagging out" with other replicas to confuse Sora.

When fighting the Guardians of Light at the Keyblade Graveyard, the Replica Xehanorts all wield the No Name Keyblade. They merge together into Armored Xehanort in order to fight Sora and Kairi and retain all of their Keyblade from their previous unfused state, as Armored Xehanort they utilize the attacks that Master Xehanort used during his time as Armored Xehanort.
