Hyper Sonic, World of Sonic Online Wiki

Hyper Sonic is a transformation of Sonic the Hedgehog, when collecting 7 Super Emeralds. Hyper Sonic looks very similar to Super Sonic, sharing the same body proportions and upturned head spikes. However, Hyper Sonic flashes in all seven colors of the Super Emeralds and has large flashing sparks floating around him. Also, when moving, he leaves several after-images.
