Earthshaker

The Earth Shaker (アースシェイカー) is a Keychain for Terra's Keyblade that is found in Kingdom Hearts Birth by Sleep. Like most Keyblades, it is a Keyblade of the Realm of Light. Terra uses this Keychain in order to form his Keyblade Ride.

Design
The Keyblade's name and Keychain (a rock fragment) refect Terra's name, which means "earth" in Latin. Its name is also shared with one of Simba's abilities.
