Hyper Knuckles

Hyper Knuckles is the form that Knuckles the Echidna changes into when he collects the seven Super Emeralds. Abilities include super speed, invincibility, and an earthquake punch that knocks out all enemies on screen when he latches onto a wall. He also glows in a hot pink and leaves after images. His first and only game appearance was in Sonic 3 & Knuckles, but he has made a couple of appearances in the Archie comic book series.
