Hyper Sonic is a transformation of Sonic the Hedgehog when harnessing the power of the seven Super Emeralds. Debuting in Sonic the Hedgehog 3 and Knuckles, this form turns Sonic's blue spikes into flashing upwardly-raised quills that switch through the colors red, blue, green, yellow, white, and violet; and has large flashing sparks floating around him.
