Hyper Sonic

Hyper Sonic (ハイパーソニック) is a super transformation of Sonic the Hedgehog that is obtained by collecting all seven Super Emeralds, which are more powerful versions of the Chaos Emeralds that have been enhanced with energy from the Master Emerald. To trigger the transformation, Sonic must also collect 50 rings and do the Insta-shield.

Appearance
Thus so far, Hyper Sonic's only appearance in-canon has been Sonic 3 & Knuckles. In Sonic 3 & Knuckles, Hyper Sonic looks very similar to Super Sonic sharing the upturned spikes, however Hyper Sonic flashes in all 7 colors of the Chaos/Super Emeralds and has large flashing sparks (similar to the invincibility item). And when running, he leaves several after-images.

Abilities
Hyper Sonic has all the benefits of Super Sonic, such as invincibility to all attacks, improved speed and strength, and greater jumping abilities. Since Hyper Sonic is generally a upgraded version of Super Sonic, Hyper Sonic has some new and improved abilities from Super Sonic, such as the ability to breathe underwater, further increased speed and strength, and a double jump attack that will destroy all enemies within the direct vicinity, excluding bosses, which is referred to by some as "Sonic Boom" or "Hyper Flash" however, the former is not an official name, and it is unconfirmed if the latter is. This is Sonic's most powerful form.

Trivia

 * Hyper Sonic's name comes from the term hypersonic, which is a speed above supersonic (generally, Mach 5).
 * By using the debug menu, it is possible to access Hyper Sonic in Sonic and Knuckles.
 * Hyper Sonic is the only transformation so far to change multiple colors flashing.
 * Hyper Sonic's silver color is the only color he has that is undetailed with only one color.
 * By using debug mode you can obtain the 8th Yellow Chaos/Super Emerald at the "level select" menu but isn't visible in the cut scene when it is collected and doesn't appear at the "save file menu" either.(The 8th Chaos/Super Emerald also gives Hyper Sonic an added gold/yellow color when he flashes.)
 * By using debug mode you can become Hyper Sonic, Hyper Knuckles, and Super Tails without any Super Emeralds if you hit the "Super" monitor when playing a level.
 * The reason Hyper Sonic never appeared ever again in games after Sonic 3 & Knuckles is because this transformation caused some gamers to have seizures.
 * Also, when using debug menu in Sonic 3 and Knuckles, having 50 rings and an insta-shield will let you transform to Hyper Sonic without any Super Emeralds.
