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 a double jump.

Abilities
Hyper Sonic has all the benefits of Super Sonic, such as invincibility, improved speed, and greater jumping abilities, but Hyper Sonic also has some improved abilities such as the ability to breathe underwater, further increased speed, power, and a double jump attack that will destroy all enemies within the direct vicinity, excluding bosses, and is referred to by some as "Sonic Boom" or a "Hyper Flash" however, the former is not an official name, and it is unconfirmed if the latter is.

Appearance
Thus far Hyper Sonic's only appearance in-canon has been Sonic 3 &amp; Knuckles. In Sonic 3 &amp; Knuckles, Hyper Sonic looked very similar to Super Sonic sharing the upturned spikes, however Hyper Sonic flashed all 7 colors of the Chaos/Super Emeralds and had large flashing sparks (similar to the invincibility item). And when running, leaves several after-images. 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.
 * Using debug mode a player can obtain the 8th Yellow Emerald at the "level select" menu but is not visible to the player when obtained (and also gives Hyper Sonic an added yellow color when he flashes).
