Green Wisp

The Green Wisp (グリーンウィスプ) is a type of Wisp which first appeared in Sonic Colors, though it only made a full appearance in the Wii version of the game. They grant Sonic the Green Hover Color Power.

Physical Appearance
The appearance of the Green Wisps resembles a spaceship. They have round bodies with a small fin on top of their head, and one blue eye in the middle of their head. Unlike most other Wisps, which have three tentacles, the Green Wisps have three sphere-like structures stemming from the body.

Sonic Colors
In Sonic Colors, when their homeworld was moved to Earth by Doctor Eggman, the Green Wisps and the rest of their race were threatened to be enslaved by Eggman, who wanted their Hyper-go-on to control the mind of everyone on Earth. Fortunately, the Green Wisps and the rest of their race were all freed thanks to Sonic the Hedgehog. After Dr. Eggman's Incredible Interstellar Amusement Park imploded into a black hole, the Green Wisps worked together with the rest of their race in stopping the black hole and succeeded, before returning with their homeworlds to their original place in the universe.

Sonic Generations
The Green Wisps made an appearance in the console/PC version of Sonic Generations, but only as a cameo during the ending credits.

Personality and Traits
Green Wisps are a pretty goofy breed of Wisp with subtle manners. As such, they can appear unexpectedly at any time, though it is advised to keep an eye out for them when flying.

Abilities and Powers
As Wisps, the Green Wisps are able to float in midair at will, which serve as their main method for movement.

The Green 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 is their life source. It is unclear to what extent they can use their own Hyper-go-on, through they have been shown being able to use it to revert Nega-Wisps back to normal, teleport objects and restrain black holes made of Hyper-go-on.

The Green Wisps are able to enter the body of other beings, as if they are intangible, and lend their Hyper-go-on to the being in question. In Sonic's case, when using a Green Wisp's Hyper-go-on, it transforms Sonic into the Green Hover, which grants him the power of flight, allowing him to reach higher areas, and to use of a move similar to the Light Speed Dash, named the Ring Dash.

Archie Comics
The Green Wisps made an appearance in the Archie Comics' adaption of Sonic Colors, in Sonic the Hedgehog #219.

In the comics, some Green Wisps and a few other Wisps were chased by Orbot, Cubot and a pack of Egg Pawns. Fortunately, Sonic arrived, and saved a Green Wisp amongst other Wisps from capture. Sonic then destroyed the Egg Pawns and send Orbot and Cubot running, though with some Green Wisps of their own. A Green Wisp then joined Sonic, Tails, Yacker and some other Wisps, as Sonic ventured out to save the Wisp race from Eggman.
