Organization XIII Device

The Organization XIII Devices are "items" which are used by Xion to power herself with a different form and weapons in her multi-form boss battle. Organization XIII used these devices to grant power to Xion to eliminate and absorb Roxas through the lingering power of Sora's true memories. Xion uses them by absorbing them, causing them to disappear.

There are three of these devices placed in three worlds that Roxas is transported to during his fight with Xion. The first one is placed in the Bizarre Room in Wonderland. The device gives Xion large, colorful wings and a huge, orange and red, intricately-shaped sword. It is unknown who placed this device.

The second device is placed in the Manor Ruins of Halloween Town. This device gives Xion a large, scythe-like weapon vaguely resembling the Decisive Pumpkin Keyblade or a Chimaera arm. It is unknown who placed this device.

The third Organization XIII device is the one that Roxas himself placed in the Cave of Wonders's Lamp Chamber in Agrabah during Mission 90: Place the device, which caused the Heartless in the area to react during the mission. This device gives Xion a figure with four huge arms, decorated with elegant, gold, purple and red designs. She also has large blades instead of hands, resembling Kurt Zisa.
