Kingdom Changer (SKW)

The Kingdom Changer is a henshin device created by GOTHOH and given to Sora, Kairi, and Riku. It lets them equip their Super Keyblade Armor, allowing them to fight Demonizer at a fairer level. It has a revolving medallion with three circles for each major function; Armor/Keyblade Equip, Schemata Shift, and Teleport.

Schemata Shift
With the voice-activated transformation call of "Schemata Shift!", Sora, Kairi, and Riku can equip the outfits of many legendary warriors and use their abilities in a similar fashion to the schema system in Lightning Returns: Final Fantasy XIII-3.

 * Following up on the recent trend of Super Sentai morphers/equipment, most notably the Gokaigers' Mobirates, having a voice, the Kingdom Changer is voiced by Hironobu Kageyama.
