Super Tails

Emeralds' power, Super Tails accordingly commands ultimate power and has access to unlimited energy.[2] As Super Tails, Tails' innate abilities far surpasses his normal ones. Not only is his strength multiplied many times over, but his speed has been greatly enhanced too, allowing him to keep up with even Super Sonic who can move at the speed of light and presumably beyond.[3][4] His reflexes are also improved, allowing him to keep up with his increased movements. Like the traditional Super State, Tails gains new abilities in this form, including high-speed run-flight without having to use his twin tails and virtual invulnerability
