Super Tails

Super Tails, Tails' Super form, only seen in Sonic 3 & Knuckles. Tails flashes yellow and is surrounded by super flickies that attack any enemy on screen. Unlike Sonic and Knuckles, Tails requires all seven Super Emeralds to achieve this form, making it really more analagous to their Hyper forms.

In the Archie comics, Super Tails was called Hyper Tails (which is itself a common misnomer for Super Tails, made common by Super Tails's similiarity to Hyper Sonic and Hyper Knuckles). He also has a form called "Turbo Tails," which was analagous to Super Sonic and to Super Knuckles (who in turn was called "Hyper Knuckles"), resulting in some confusion.
