Purple Wisp

The Purple Wisp appears in Sonic Colors, exclusive to the Wii version. It gives Sonic the Purple Frenzy ability, which allows him to become a beserk chomper that eats anything in its way. It will also increase in size as long as it continues to eat.

Appearance
Being a wisp corrupted by Dr. Eggman's evil control, the Purple Wisp has a more menacing look than all of the other Wisps. It has three tentacles stemming from the pointed head, which only has a mouth on it.
