Yellow Wisp

The Yellow Wisp (イエローウィスプ) is a type of Wisp which first appeared on both the Wii and Nintendo DS version of Sonic Colors. They grant Sonic the Yellow Drill Color Power.

Physical Appearance
The Yellow Wisps have a triangular head with one orange eye in the middle. Their head is covered in orange and yellow stripes. They have three tentacles stemming from the head. Their appearance resembles that of the White Wisp, but they have no antennae and a triangular-shaped head, resembling a drill.

Sonic Colors
The Yellow Wisps made their first appearance in both versions of Sonic Colors. When their homeworld was moved to Earth by Doctor Eggman, the Yellow 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 Yellow 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 Yellow 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.

The Yellow Wisps appear in Tropical Resort, Sweet Mountain and Aquarium Park on the Wii version of the game, and in Planet Wisp and Aquarium Park on the Nintendo DS version.

Sonic Generations
The Yellow Wisps made a cameo on the console/PC version of Sonic Generations, where they appeared during the ending credits.

Sonic Lost World
The Yellow Wisps made a reappearance in both the Wii U and Nintendo 3DS version of Sonic Lost World. They appear in Desert Ruins, Tropical Coast and Silent Forest on the Wii U version, and Desert Ruins, Tropical Coast and Lava Mountain on the Nintendo 3DS version.

Personality and Traits
Yellow Wisps are very energetic and playful. They are naturalistic by nature and are very fond of earth and water. Sonic also compares the Yellow Wisps to Knuckles the Echidna because of their energetic nature.

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

The Yellow 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, carry objects through levitation and teleport objects.

The Yellow 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 Yellow Wisp's Hyper-go-on, it transforms him into the Yellow Drill, which gives him the ability to drill underground or to move through water like a torpedo.

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

In the comics, some Yellow Wisps and a few other Wisps were chased by Orbot, Cubot and a pack of Egg Pawns, but one Yellow Wisp was saved by Sonic. After Sonic destroyed the Egg Pawns and send Orbot and Cubot running. A Yellow Wisp then joined Sonic, Tails, Yacker and some other Wisps, as Sonic ventured out to save the Wisp race from Eggman.
