Sonic is the fastest of all three playable characters in SRB2, but he's also the least versatile. His special ability is the double-jump "Air Spin Attack", or the "thok", named after the sound it makes. The thok gives the player a burst of speed, which is useful for clearing wide gaps and automatically giving acceleration. Because he cannot gain any height aside from jumping, many areas will be inaccessible to him, so he must find other routes around them. Due to his high speed, he's also somewhat difficult to control, especially when using his special ability.
Another special ability characteristic of Sonic is his super transformation. When given seven Chaos Emeralds and fifty rings, Sonic can become the golden Super Sonic, making him faster and stronger for a certain period of time. Super Sonic is completely invincible to everything except drowning, deathpits, and getting crushed— but be careful. Your rings drain by the second, and once they reach zero, Sonic turns back to normal, making him vulnerable to everything he once was.
When Super Sonic is used in Match, he has the same abilities that he has when he is used in Single Player. He is also the only character who has specialized Super sprites, which makes him easily identifiable in Match.
