The appearance of the Green Wisps resembles a spaceship. They have round bodies with a small fin on top of their heads and one blue eye in the middle of their heads. Unlike most other Wisps, which have three tentacles, the Green Wisps have three sphere-like structures stemming from the bottom of their bodies.
The Green Wisps made their first appearance in the Wii version and Nintendo DSversion 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 to stop the black hole and succeeded, before returning their homeworlds to their original places in the universe.
Mario & Sonic at the Sochi 2014 Olympic Winter Games
In Mario & Sonic at the Sochi 2014 Olympic Winter Games, the Green Wisp makes an appearance 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 will appear alongside several others Wisps and join up with the four characters to perform the Final Color Blaster, which deals the final blow on the Rotatatron..
Being Wisps, the Green Wisps are halcyon and social. Overall, they are peaceful, playful, non-hostile and friendly of nature, and enjoy spending most of their time playing with others. While they are not fighters, they are nonetheless brave and very helpful towards their friends and allies.
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 by phasing into the recipient. When organic beings or robots receive their Hyper-go-on, they can transform into the Green Hover which enables flight and the Ring Dash maneuver. Alternatively, the Green Wisps are able to manifest the Green Hover's power themselves without phasing into a recipient.
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.
In the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing, the Green Wisps are aliens from Planet Wisp. Much like in the games, some of them have settled down on Sonic's world where they help out the planet's inhabitants from time to time.
