The Black Wisps have a red jagged mouth-like recess stretching across their head. Stemming from the bottom of their head, they have three round tentacles with a slight rounded point at the end of them. They also appear to have two round and puffed cheeks on the sides of their head.
Unlike other Wisps, the Black Wisp are only available in Sonic Lost World by obtaining it from the Miiverse. It can also be rewarded to the player by completing the exclusive NiGHTMARE DLC content, which is available in Deadly Six (Bonus) Edition or the Yoshi's Island Zone DLC of Sonic Lost World.
Powers and abilities
As Wisps, the Black Wisps are able to levitate in midair at will, which serve as their main method for movement.
The Black 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.
The Black 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 Black Bomb which can induce explosions.
The Black Wisps share some similarities with the Purple Wisps and Violet Wisps from Sonic Colors, as they are dark-shaded colors and have jagged mouths as opposed to eyes. Any connection between the Black Wisps and Nega-Wisps is unknown.
