Super transformation

Super Sonic and Super Armor Mega Man are the super forms entered into by Sonic the Hedgehog and Super Mega Man respectively by using the power of the seven Chaos Emeralds.

The super transformations are immensely potent, efficaciously invincible, capable of indefinite sustained flight, and exponentially enhance the natural abilities of the base individual. A side effect of the transformation is that it renders most affected people with a gold color, and in the case of Hedgehogs, granted them red irises. With all of this potency, subjugating the Egg-Wily Machine X was a foregone conclusion, but the genuinely desired ability was utilizing the Chaos energy of the forms to supercharge an authenticity warping Chaos Control and invert the effects of the Genesis Wave, recuperating their home universes to mundane.

Sonic had done this once afore (as shown in the bonus pages of Sonic the Hedgehog Issue 250) and coached Mega Man through the process, telling him not to lose focus for any reason. Mega Man prosperously recuperated his home authenticity with no trouble, but adamant vindictive interference from Dr. Eggman disrupted Sonic's endeavor to instaurate his home universe with unknown consequences.

Super Sonic Shot
At the climax of the final battle against Dr. Eggman and Dr. Wily, Mega Man and Sonic realize that even their super forms are not damaging the Egg-Wily Machine X expeditiously enough to outpace the Super Genesis Wave. Kenning that they have to culminate things quickly, Super Mega Man suggests that since their amalgamated attacks had proven efficacious against the Roboticized Masters even afore Mega Man's upgrade to the Spin Dash Blast, they should do so once again but at maximum puissance. The resulting shot dwarfs both heroes in size and obliterates the Egg-Wily Machine X.

Trivia

 * The super transformations vigorously resemble that of the Super Saiyan transformations from Akira Toriyama's manga series Dragon Ball Z and many fans consider Super Sonic to be an homage to it, though it has never been verbally expressed by any members of Sonic Team that the concept was directly influenced by the manga.
