Gray Wisp

The Gray Wisp (グレイウィスプ) is a type of Wisp that is exclusive to the Nintendo 3DS version of Sonic Lost World. They grant Sonic the Gray Quake Color Power. They appear in Desert Ruins, Frozen Factory, Silent Forest and Lava Mountain.

Appearance
The Gray Wisps' overall appearance resembles that of a rock. Their bodies are in the shape of a boulder and a tetradecahedron, looking similar to a rough rock. They also have three regular octahedron-shaped tentacles stemming from under their body, and have three pink eyes arranged in a triangle.

Powers and abilities
As Wisps, the Gray Wisps are able to levitate in midair at will, which serve as their main method for movement.

Like all Wisps, the Gray Wisps are able to generate and store their own unique variant of a powerful energy known as Hyper-go-on inside their own bodies, which doubles as their life source. It is unclear to what extent they can use their own Hyper-go-on.

The Gray Wisps are able to phase into the body of other beings and lend their Hyper-go-on to the being in question. In Sonic's case, when using a Gray Wisp's Hyper-go-on, it transforms him into the Gray Quake, which lets him create quakes by falling down heights.

Trivia

 * In terms of design, this Wisp has some similarities to the Blue Wisp.
 * This Wisp is one of only four Wisp types to have three eyes, the others being the Red Wisp, the Crimson Wisp and the Blue Wisp.
