Hyper Knuckles, Sonic Wiki Zone

Hyper Knuckles (ハイパーナックルズ, Haipā Nakkuruzu?) is a transformation that appears in the Sonic the Hedgehog series. It is the Hyper State of Knuckles the Echidna, being gained by tapping into the power of seven Super Emeralds. </i>."> As he appears identical to Super Knuckles, Knuckles does not receive any physical changes during this transformation, but his fur pulses from red to a whitish pink. Unlike his Super State, however, any fast movement he makes leaves after-images, similar to Hyper Sonic.
