Green Wisps are subtle, yet pretty goofy. You never know when you might come across one, but keep an eye out for them when you’re flying. They give Sonic the power to hover. — Description of the Green Wisp, Sonic Colors
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.
The Green Wisps made their first appearance on both versions of Sonic Colors, though they only appear during cutscenes on the Nintendo DS version. When their homeworld was moved to Earth by Dr. Eggman in order to create his interstellar amusement park, 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 using a weapon. 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.
Mario & Sonic at the Sochi 2014 Olympic Winter Games
The Green Wisps made an appearance in the Mario & Sonic at the Sochi 2014 Olympic Winter Games during the Dream Event, Sonic's Figure Skating Spectacular. Here, a Green Wisp is one of the Wisps that the four participating characters free from a Wisp Capsule as the player(s) proceed down the event's course. When the player then has to defeat the Rotatatron, the Green Wisp appears and joins the other Wisps that were freed during the event and later the four characters in perform the Final Color Blaster, which deals the final blow on the Rotatatron.
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.
Powers and abilities
The Green Wisps are able to levitate in midair at will, which serves as their main method of transportation.
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 pass on a fraction of their Hyper-go-on to other beings by phasing into their body, which allows them to transform into the Green Hover which enables flight and the Ring Dash maneuver.
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.
