Origin
Throughout the Sonic games, starting with Sonic the Hedgehog 2, 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 Sonic the Hedgehog 3, 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 can destroy enemies merely by touch. However, because of his immense speed, the player could easily fall victim to pitfalls, the one thing he is still weak against. In addition, the Super form does not last for long as it consumes the player's Rings constantly, and thus the player must continue to grab Rings to maintain the state. Beginning with Sonic Adventure 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.

Trivia
