Hyper Sonic

Hyper Sonic (ハイパーソニック Haipā Sonikku) is the hyper transformation of Sonic the Hedgehog. It is transformed by the power of the Super Emeralds (Super Chaos Emeralds), which makes Sonic flashes the colors of the seven Chaos Emeralds into a rainbow of colors, mainly white.

So far, this form has only appeared in Sonic the Hedgehog 3 & Knuckles, but some western fans, albeit unofficially, have hyper-enhanced Modern Sonic with mods.
