Spin Dash

The Spin Dash (スピンダッシュ), also called as the Super Dash Attack and Super Spin Dash (超スピンダッシュ), is Sonic's trademark technique and a variant of the Spin Attack where the user blasts forward with a revved-up Spin Attack from a stationary position. Since its introduction, it has become one of the most well-known and frequently used moves throughout the Sonic the Hedgehog series.

Description
The Spin Dash was developed by Sonic, who claimed it came to him one day during his "Genesis days" when he tried combining a somersault with running.

When performing the Spin Dash, the user crouches down, performs an oval-shaped charge (called the Spin Charge) and then dashes off into a high speed rolling attack. While in this state, the player can shred through any unprotected enemy, break through walls, and dash up steep slopes without having to build up running momentum. However, the characters are not invulnerable while Spin Dashing, as colliding with spikes and other hazards still causes damage. Usually, the player has to press down on and tap the jump button to execute the Spin Charge. After gaining enough speed, the player must release the down button to shoot character off. Some games have different ways to do the move, however.

While the Spin Dash has become a trademark move for Sonic the Hedgehog, some characters can also use it and have even created their own variations of it.

Sonic X
The Spin Dash in Sonic X has been performed numerous times during the series run, mainly performed by Sonic and Shadow.
