The main star of the Sonic the Hedgehog series. He's an easygoing hedgehog who blows past the competition with his speed. Seriously, on the ground he's faster than anyone else in Smash Bros. Use this to your advantage, avoiding blows while landing lightning-fast attacks.
Sonic's up special Spring Jump lets him reach great heights by jumping on a spring, becoming invincible for a moment. He can't use any other specials during the jump, but he can attack or dodge. This move's great for returning from a long launch. Other fighters can use the spring, though!
