Kingdom Key

The most prominent and famous Keyblade is the Kingdom Key. It represents Disney Castle in all Kingdom Hearts games. The key chain (the Mickey Mouse insignia) attached draws out the Keyblade's true form and power.

Sora obtained the Kingdom Key during the destruction of the Destiny Islands. Mickey Mouse uses a similar weapon, but how he obtained it is not known.
