In the various official Sonic the Hedgehog series media, a variety of Super transformations appear. Most are similar to the forms in the games, but there are some notably different ones. This articles covers the various super forms in these different media. Like the super transformations of the games, many of the forms featured in other media are granted by use of the Chaos Emeralds or the Master Emerald.
Supreme High Robotnik
In the Quest for the Chaos Emeralds saga, Robotnik travels across time and collects the four Chaos Emeralds of Invisibility, Invincibility, Immortality and Life. When placed around his neck, he becomes the Supreme High Robotnik. In this form, Robotnik becomes giant with rippling muscles and long fingernails, and can use any of the powers at will. However, once the emeralds are removed, he reverts back to normal Robotnik.
Although not technically a 'Super Form' transformation, Sonic and Princess Sally Acorn harness the energies of the Deep Power Stones to achieve extraordinary powers in order to thwart Robotnik's Doomsday Project in the finale episode, which had the same name. While imbued with the power of the stones, both Sonic and Sally were surrounded by glowing violet energy auras and could move at blinding speeds, tearing apart Robotnik's entire operation in a matter of seconds. It also seemed to have some lingering effects, such as producing a small shockwave when Sally and Sonic gave each other a high-five, and shooting up fireworks when the two kiss near the end of the episode. Presumably, like a standard Super transformation, this ambient energy would have been temporary.
Archie Sonic the Hedgehog
While the games and Sonic X only use Super and Hyper Forms, the Sonic the Hedgehog Comic Series has the largest variety of transformations for various characters. Several characters have as many as three super forms, and the comics are also the first to introduce the concept of super forms that would have lasted indefinitely were it not for certain circumstances.
The Complete Sonic Encyclopedia mentioned that anyone can go super but can only master the form with training.
Sonic the Hedgehog
In the Sonic the Hedgehog comics published by Archie Comics, Super Sonic is one of Sonic the Hedgehog's super-powered forms. In this series, Super Sonic first appeared during the series' more comical era. There, he battled a roboticized and enlarged lizard calling itself the "Universalamander". At the end of the issue, he would still have a "super" sense of humor by putting a whoopee cushion on Antoine's chair. He does not reappear until the 48-page special Super Sonic vs. Hyper Knuckles (Hyper Knuckles was what the comics used to refer to Knuckles' seven-emerald form rather than the higher level), and then makes numerous appearances later on, including where he battled the emerald-empowered Master Mogul, along with Hyper Knuckles and Turbo Tails, and the battle against Perfect Chaos in the Sonic Adventure adaptation. Afterwards, Super Sonic made a return appearance when Sonic discovered red-colored emeralds on an alien world, causing Super Sonic to be born as a crazed lunatic, separate from Sonic himself (similar to Fleetway's version of Super Sonic). This duplicate's existence ended when his powers faded. When A.D.A.M. (controlling Tommy Turtle) successfully gathers all of the Chaos Emeralds in the universe, Sonic shows up to battle A.D.A.M. and uses the energy from the Emeralds to transform into Super Sonic once more. Unfortunately, A.D.A.M. was also able to use the power of the emeralds to ascend to the level of Super, and fought Super Sonic to a standstill until Tommy temporarily regained control and allowed himself to be destroyed by Robotnik's Egg Fleet. Later, during the return of Knuckles' old arch-nemesis Enerjak, who was eventually revealed to be Knuckles himself brainwashed by Dr. Finitevus, Sonic rushed back to the Master Emerald and absorbed some of its power to transform himself into Super Sonic (neutralizing Finitevus' tainted spell on the Emerald in the process), so he could battle and save his converted friend.
Sonic also has the ability to transform into Ultra Sonic when empowered by the vast energies of one of this setting's version of the Super Emeralds — it resembles Hyper Sonic in some ways, but Sonic's fur color does not change. He merely gains greater strength and speed, as well as elemental powers: he was able to generate water and create walls of rock. Ultra Sonic also appears to be almost a separate consciousness from Sonic; after transforming back from him the first time, Sonic had no recollection of the transformation. In addition, in this form, Ultra Sonic can transform into various elemental forms based on his environment, such as Solar Sonic, Eco Sonic, and Polar Sonic. He only took on these additional personas once, when he used the power of a Super Emerald to enhance his speed and save Knothole village from a temporal beam fired by a satellite controlled by none other than Robo-Robotnik. As a result of exposure to this energy, Sonic took on the design seen in games beginning with Sonic Adventure.
Ultra Sonic is generally considered to be Sonic's second super transformation, whereas Super Sonic is his first. Solar, Eco, and Polar Sonics are all transformations based upon Sonic's location on the globe: Solar comes from being in hot areas, Eco from forest areas, and Polar from cold areas. Ultra Sonic's abilities far surpass Super Sonic's abilities. In this form he has the ability to manipulate the elements and his voice changes, he is also substantially faster than his previous incarnation.
Following the defeat of Ixis Naugus in the Super Special #4, Sonic and Tails set off in an adventure around Mobius which eventually takes them to Nate's castle in the far north. It is here where they find a near limitless supply of power rings (specific number if not stated, but it is assumed to be numbered in the thousands.) Comparatively, the first transformation requires 50 power rings and 7 chaos emeralds, thus the power of several thousand power rings is sufficient to bring Sonic and Tails to their second transformations. It is revealed during this arc that Ixis Naugus' purpose was to find Nate Morgan's power ring storehouse, and take it's power for himself, whereby he would open the Zone of Silence and merge it with the reality of Mobius Prime, thus gaining ultimate power. The ensuing battle allowed Sonic, Tails, and Naugus to divide the power rings between the three, thus causing transformations in all of them. Thus Sonic was joined by Hyper Tails (who was also treated as a second transformation with thousands of rings and a form very similar to the games' version) in a battle against Ixis Naugus.
Miles "Tails" Prower
Knuckles the Echidna
Shadow the Hedgehog
After absorbing a huge but unspecified number of Power Rings, Ixis Naugus attained a power level akin to that of Ultra Sonic, Hyper Tails, and Super Knuckles. While in this state, he battled Ultra Sonic and Hyper Tails but was defeated despite the fact that their power ran out faster than his did due to the intervention of Nate Morgan. In this form, he was able to open a portal to the Zone of Silence with the intent of merging it with Mobius to make himself all-powerful. This improved Naugus also could generate beams of fire from his eyes, create ice from the air, and summon torrents of water. Since then, he has not attained this level of power again, and no name was ever given for this incarnation. Naugus has also failed to assume any other forms of higher power than he is normally capable of.
During the "gathering" of all the Chaos Emeralds in the universe, A.D.A.M. was confronted by Super Sonic. Using the vast amount of Emeralds in the area, he was able to achieve his own Super form, but was ultimately destroyed when Tommy Turtle managed to regain control of his body (which A.D.A.M. had taken possession of using the nanites in his shell) and flew into the massed fire of Dr. Eggman's Egg Fleet, apparently killing them both. As is the case with Ixis Naugus, no name was given to A.D.A.M.'s powered up form, though "Super A.D.A.M." seems likely.
Super Armor Mega Man
During the last issue of Sonic & Mega Man: Worlds Collide, Sonic instructs Megaman to help him reach the Chaos Emeralds, allowing Mega Man assumed a Super form alongside Sonic. He later uses the power of Chaos Control to restore his world back to normal.
After obtaining all seven Sol Emeralds within the Egg O' War, Blaze was able to transform into Burning Blaze. She then used the form she got from her super form to destroy Captain Metal's body and then the Egg O' War which Captain Metal had uploaded himself into.
