Earthshaker

The Earthshaker (アースシェイカー) is the default form of Terra's Keyblade which appears 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 Glider.

Design
The shaft of Earthshaker has a textured, dark brown color, with brass edges. The teeth are made of two pick-like points, with two hammer-like protrusions on the opposite side. The guard is an off-blue color, and seems to be crafted from two Omega insignias (Ω). The pommel is a dark blue cone. The Keychain token is a reddish rock fragment with brass armor-like plating.

The Keyblade's name and Keychain reflect Terra's name, which means "earth" in Latin. Its name is also shared with one of Simba's abilities.
