Hyper Knuckles

Hyper Knuckles is Knuckles the Echidna's hyper transformation that is gained when he taps into the power of seven Super Emeralds and fifty rings. His only game appearance was in Sonic the Hedgehog 3 & Knuckles.

Overview
Like Super Knuckles, Knuckles does not receive any physical transformation, but his fur pulses from red to pink. Unlike his Super State, however, any fast movement he makes leaves after-images.

Powers and Abilities
While in Hyper form, Knuckles' natural abilities are multiplied many times over; his already impressive strength, speed and accuracy increase vastly, and he is virtually invulnerable as long as the transformation lasts. Since Hyper Knuckles is an enhanced version of Super Knuckles, all of his physical abilities surpass that of Super Knuckles and he gains additional abilities as well. When gliding into a wall, Hyper Knuckles can perform the "Gliding Shock Wave Attack" which causes an earthquake that destroys all enemies on the screen, and he can breathe underwater as well.

Like most other super transformations, caused by the Chaos Emeralds/Super Emeralds, once he runs out of rings, he returns to his normal form.
