Wisps

Wisps are the alien creatures that appear in the Marvel Storybook 2 (Game) and Marvel Storybook (Movie). They are a diminutive, yet powerful alien species from Planet Wisp, although they can be found on many other planets across the universe. During one of Dr. Eggman's plots, the Wisps were kidnapped and enslaved by the doctor until Sonic the Hedgehog freed them. While most of the Wisps went home after that, some of them decided to stay on Sonic's world after taking a liking to it. Now, in remembrance of Sonic's deeds, the Wisps are ready to offer him and his allies help whenever needed.

There are numerous breeds of Wisps, each with its own special ability and personality traits. When a Wisp enters a person, they bestow upon them a certain Color Power that grants them new and powerful abilities.

Appearance
They are little aliens, but they appear to be different colors.

Concept And Creation
Takashi Iizuka stated in an interview that the Wisps were added to Sonic Colors to "expand and strengthen the platform action gameplay" without forcing the player to switch to other playable characters. Another goal was to encourage players to revisit already-played levels; Sonic Team accomplished this by adding segments requiring certain types of Wisps to levels preceding their first appearances.

Following the success of Sonic Colors, Iizuka has stated that he now considers them a staple in the Sonic series. Since then, the Wisps have appeared in multiple successive Sonic titles.

First Appearances
The Wisps appear in the opening cutscene after they are escaping the Advanced Death Egg and go back home in Wisp Planet.
