Once Dr. Eggman captures a Wisp, he transforms it into a Nega-Wisp, such as the Violet Wisp. Be careful, as these violent creatures will bark and bite! They also have the power to transform Sonic into a Violet Void.
— Description of the Violet Wisp, Sonic Colors
Being a Nega-Wisp, the Violet Wisps have a more menacing look than other Wisps. Their head is round with five curved-back tentacles around it, making it look like a swirl. They lack eyes, unlike normal Wisps, and instead have a serrated mouth that look like a menacing grin. They also have three wide tentacles, stemming from their head, and end in a jagged point.
The Violet Wisps appear on both versions of Sonic Colors, though they only appear during cutscenes on the Wii. The Violet Wisps were originally normal Wisps, until they were captured by Dr. Eggman during Sonic Colors and syphoned dry of their Hyper-go-on in an attempt on the doctor's behalf to take over Earth with a Mind Control Ray. This process, however, mutated these unfortunate Wisps into the corrupted Violet Wisps, who were forced to carry out Eggman's evil plans. Near the end of Sonic Colors, however, all of the Violet Wisps were returned to normal by the remainder of the Wisp race with their own Hyper-go-on, who had been freed by Sonic the Hedgehog.
Unlike normal Wisps, who have playful personalities, the Violet Wisps are rather violent. Because of their mutation, the Violet Wisps' mindset is that of a wild and feral animal, and they will threaten others by biting and barking if approached.
Powers and abilities
The Violet Wisps are able to levitate in midair at will, which serves as their main method of transportation.
The Violet 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. However, due to their mutation, the Violet Wisps' Hyper-go-on has been corrupted, resulting in a darker and negative version of their Hyper-go-on. It is unclear to what extent they can use their own Hyper-go-on.
The Violet 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 Violet Void which can suck objects into oblivion.
