Earthshaker

Unreleased

Terra's Keyblade is a Keyblade used by Terra during his quest to find Master Xehanort.

Terra is shown summoning his Keyblade differently than how most wielders do. Like Ven and Aqua's Keyblades, it lacks a keychain. These two facts are speculated to be related.

Kingdom Hearts II: Final Mix
Terra uses this Keyblade to fight Sora after they save Disney Castle from the plunging darkness and so gives access to a wormhole in Kingdom Hearts II: Final Mix+.

During battle, Terra can change the Keyblade into a whip, a jet-ski like object, a fast spinning cog-like weapon, and a massive cannon, among other formations. It is unknown if Terra will have this ability in Birth By Sleep or if it only appears in his boss battle with Sora.
