Super Sonic is a special form that Sonic takes on after collecting the seven Chaos Emeralds. His super form grants him increased speed, the power of flight and turns his blue quills upward and golden yellow. Super Sonic is usually invincible to attacks, though he can die by being crushed or falling off screen. Making its debut in Sonic The Hedgehog 2, the form is often attributed to being a nod to the Super Saiyan form from the popular anime Dragon Ball, with the seven Chaos Emeralds also matching the number of Dragon Balls. Since being introduced, Super Sonic has appeared in nearly all the home console games that he has appeared in, with a couple of exceptions, for example being replaced by Darkspine Sonic in Sonic and the Secret Rings. Super Sonic has also recently found his way into the many party games that Sonic has taken part in, for example, Super Smash Bros. Brawl as his Final Smash and Sega Superstars Tennis. In his most recent outings in the main series, Super Sonic is often saved for a special one-off boss fight at the end of the game, unlike his first appearances which allowed you to take control of him during in-game levels.
