Makes transform Sonic into a cosmic ball that vacuums everything on his path. While he's vacuuming, he grows too.
The Violet Wisp (also known as a Void Wisp) is a Wisp that made it's first appearance in Sonic Colors. It is one of the few Nega-Wisps, an unnaturally derived subspecies drained from their Hyper-go-on energy. The Violet Wisp helps out by turning Sonic into a black hole and makes him suck enemies and rings. The Violet Wisp is very helpful whenever a hoard of enemies is passing by and whenever an enemy is sucked, Sonic grows larger.
