Super Sonic (Final Smash)

Super Sonic is 's Final Smash in Super Smash Flash 2.

Overview
When performed, Sonic shouts "Now I'll show you!" and uses the seven Chaos Emeralds to transform into Super Sonic, in which his blue fur turns into a gold color, his green irises become red, and his quills turn upward. In this state, Sonic gains the ability to freely fly around the stage at an incredible speed and is completely invincible for its duration. He attacks opponents by making contact with them, dealing more damage and knockback based on how fast he is traveling. When not moving, he deals 3% damage with weak knockback, and at his maximum speed, he deals 29% damage and strong knockback. After approximately 18 seconds, the Chaos Emeralds will disperse as Super Sonic transforms back into his original form, ending the move.

Origin
Throughout the ' games, starting with ', Super Sonic has been the super form of Sonic when he collects all seven Chaos Emeralds. In the early games, the Chaos Emeralds were hidden in Special Stages and were treated as an unlockable feature in the games, and starting with , other characters were also capable of attaining Super forms, such as Knuckles. Whilst in Super form, Sonic will act under the influence of the Invincibility and Speed-Up items and gains the ability to fly, drastically increasing his speed and allowing him to destroy enemies merely by touch. However, because of his immense speed, the player could easily fall victim to pitfalls. In addition, the Super form does not last for long, as it consumes the player's Rings constantly, so the player must continue to grab Rings to maintain the state. Beginning with  and up to Sonic Unleashed, Super Sonic is generally only available for play in the final boss battles, which require him to defeat a similarly powered-up major antagonist. More recent Sonic games, however, have since generally allowed Super Sonic to be usable in the games' levels as before, excluding with certain boss battles.
