Indigo Wisp

The Indigo Wisp is a type of Wisp that first appeared in the Wii U and Nintendo 3DS version of Sonic Lost World. They grant Sonic the Indigo Asteroid Color Power.

Appearance
The Indigo Wisps have a nearly-perfect-sphere-shaped head with one violet eye. They also have three round tentacles stemming from the bottom of their heads, and a small, round antenna on top of their heads. Most noticeably, they also have a violet ring, similar to a planetary ring, encircling their head.

Sonic Lost World
The Indigo Wisps made their debut in both versions of Sonic Lost World

They appear only in Windy Hill on the Wii U version, but on the Nintendo 3DS version they are found in Windy Hill, Desert Ruins, Sky Road and Lava Mountain.

Sonic Runners
In Sonic Runners, the Indigo Wisps appear as a part of the Indigo Asteroid Equippable Item which enables players to float and destroy various obstacles.

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

They 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.

The Indigo 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 Indigo Wisp's Hyper-go-on, it transforms him into the Indigo Asteroid, which allows him to create a powerful gravitational field around himself.
