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; his appears surrounded by translucent blocks in a flash of light, similar to how Roxas first summons the Kingdom Key in the Simulated Twilight Town.

Like Ven and Aqua's Keyblades, it lacks a keychain. Because it lacks a chain, it is rumored to be a "false" Keyblade, however, this may only be speculation.

The name of this Keyblade is rumored to be Enigma, but that name has never been used for it by any official source. It may also be called Farglenarb.

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.
