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 powerful, effectively invincible, capable of indefinite sustained flight, and exponentially enhance the natural abilities of the base individual. With all of this power, defeating the Egg-Wily Machine X was a foregone conclusion, but the truly desired ability was using the Chaos energy of the forms to supercharge a reality warping Chaos Control and reverse the effects of the Genesis Wave, restoring their home universes to normal.

Sonic had done this once before (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 successfully restored his home reality with no trouble, but stubborn vindictive interference from Dr. Eggman disrupted Sonic's attempt to restore 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 quickly enough to outpace the Super Genesis Wave. Knowing that they have to finish things quickly, Super Mega Man suggests that since their combined attacks had proven effective against the Roboticized Masters even before Mega Man's upgrade to the Spin Dash Blast that they do so once more at maximum power. The resulting shot dwarfs both heroes in size and obliterates the Egg-Wily Machine X.
