Design
The tip of the Hyperdrive's blade appears to be the red police cruiser that Experiment 626 used to escape to Earth in Lilo & Stitch. A light green blast of plasma comes from the ship's lasers, with three circular points serving as the teeth, while the shaft of the blade, which has a distinctive helix shape, is the blue exhaust from the ship's engines; for Terra's version there are three loops, while for Ventus's and Aqua's, there is only one. The guard has the appearance of spaceship technology, with a small display screen embedded near the base of the shaft. The hilt has three yellow and three black stripes, the same color pattern of. The Keychain resembles a thick blue wire fading from light to dark as it goes down, and the token is one of Experiment 626's blasters.

A "hyperdrive" is a powerful type of engine that appears frequently in science fiction, including Lilo & Sitch and the Deep Space world.
