Hyper Sonic is a hyper transformation of Sonic the Hedgehog that is obtained by collecting all seven Super Emeralds, Chaos Emeralds that have been enhanced by the Master Emerald. To trigger the transformation, Sonic must collect at least fifty Rings and perform the Insta-shield. To this date, Hyper Sonic is recognized as the most powerful form of Sonic ever.

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 Chaos/Super Emeralds and has large flashing sparks floating around him. Also, when moving, he leaves several after-images.
