Spin Dash (Sonic)

Spin Dash is 's, ' and 's down attack in Super Smash Flash and is  and ' down special move in Super Smash Flash 2. It was also originally Super Sonic's side special move prior to Beta, where Super Sonic no longer has access to special moves.

Overview
Each character's version of the attack has specific characteristics. Sonic's Spin Dash is fast, can be controlled well, can do jumps, and can change direction at will, which is required in order to keep his Spin Dash going. Tails' Spin Dash is much faster than Sonic's, can not be controlled, stops once he hits an opponent, only goes in the direction he is facing, can be used in the air and out-prioritizes most projectiles. If Tails short hops a spin dash, lands on the ground and jumps again (using a second jump or external jump button) he will perform a pseudo wavedash.

Super Sonic's Spin Dash was more powerful, easier to control, could do more damage than Sonic's, would last longer than Sonic's, could also do jumps, and could only go in the direction he faced when he initiated the move. It also would move forward while he is charging it. It replaced his Sonic Wave in v0.7 of the SSF2 Demo. Spin Dash could be canceled by pressing the special move button.

Spin shot
The Spin Shot is a fast, long-reaching short hop. Sonic gains the momentum from the spin dash and jump cancels the move upon releasing the special. The Spin Shot is mostly performed with Sonic's forward aerial. It is performed by charging the spin dash and jumping upon releasing the special button while pushing forward and the attack button. It has to be timed right in order to gain the momentum from the spin dash.

Spinning bounce shot
The Spinning bounce shot is an advanced version of the Spin Shot. Sonic still gains the momentum from canceling the spin dash but this uses the Bounce Attack instead and after landing it, he regains his second jump. But, if it is launched too far, the move would end in a SD. It is performed by charging the spin dash and jumping upon releasing the special button then pressing the down special input. This advanced technique was found by McLeodGaming Forums user, BlueFirebird.

Trivia

 * Prior to SSF2 Beta, when performing Sonic's down special move in the air, he instead performed a different attack called the Bounce Attack which was removed for unknown reasons.
 * The fan-made characters and  from the original SSF are also able to use the Spin Dash as part of their movesets: They are, however, unable to charge the move, which means the attacks comes out sooner and travel a fixed set distance, they also slash with their swords when they are curled.
