Super Tails

When "Tails" uses the transformation, he becomes Super Tails. This originally occurred in Sonic 3 & Knuckles, where the player needed the seven Super Emeralds to transform.[7] Tails did not change color, but instead glowed and was surrounded by four Flickies. The Flickies surrounding him instantly attacking any nearby mechanical enemies, including bosses.

Tails's next use of super transformation occurs in Sonic Heroes. Here, the player only needs to obtain the seven Chaos Emeralds and complete the game to transform. His appearance is slightly modified from the original "Super" Tails, with the addition of a golden energy sphere and the removal of the Flickies. Tails is invulnerable in this form and gains an enhancement to his normal "Thunder Shoot" ability.[6]
