Replica Kingdom Key
From the Kingdom Hearts Wiki: A world of information not accessible by Gummiship
Kingdom Hearts III
The Replica Kingdom Key is identical to the Kingdom Key, which is depicted as a classic skeleton key approximately 3.5' long, with a long silver Keychain extending from the hilt, and a Hidden Mickey token on the end of the Keychain. The blade and teeth of the Keyblade are silver, the rainguard is blue, and the guard is bright gold. The teeth of the Keyblade form the outline of a crown which matches the crown charm Sora wears.
Xion, while still lacking free will, could replace her Replica Kingdom Key with a copy of Lunatic whenever Saïx entered his berseker state.
