List of techniques used in Sonic games

Sonic the Hedgehog

 * Spin Dash: Sonic's signature move. Although the attack is shared with many others in the series, Sonic is able to make the most out of it. He's able to do more with it than just dash; he can pummel opponents, create shields, home in on opponents, and even travel at the speed of light. He uses this attack more than any other one he has in his arsenal.
 * Light Speed Dash: One of the extenstions of Sonic's Spin Dash. Though just a variation, it's probably the most different from the origninal Spin Dash compared to all the other forms of it he has. The attack allows Sonic to travel through a stream of Rings at the speed of light.
 * Sweep Kick: This is one of Sonic's moves from Sonic the Hedgehog: 15th Anniversary. Sonic simply spins with his leg extended in a 360 degree circle. This attack can also generate a tornado if Sonic spun fast enough. It's also been used in Super Smash Bros. Brawl as his down tilt attack and returned as a special move in Sonic Unleashed.
 * Skid: Sonic somersaults and slides along the ground. Meant for attacking enemies near Sonic. While Boosting, this attack becomes a bit more useful as Sonic doesn't instantly stop when doing it.
 * Speed Up: When enough Rings are obtained, Sonic is able to give himself a quick boost in speed. It can't be used to attack enemies, but it's a good way to increase Sonic's acceleration.
 * Sonic Wind: This is one of Sonic's moves from Sonic Adventure 2. When he has enough Rings, Sonic can create a tornado of wind that warps to his opponent and harms them. He can use a similar attack in Sonic Heroes called the Blue Tornado.
 * Time Stop: Another move from Sonic Adventure 2, Time Stop allows Sonic to temporarily pause time with enough Rings. Sonic can pause time for a maximum of 20 seconds, and he's free to attack his opponent if he/she happens to be in his way.
 * Sonic Boost: Hailing from Sonic Rush, the Sonic Boost enables Sonic to instantly reach his highest possible speed while running. He knocks out any enemies that are in his path.

Super Sonic

 * Rushing Attack: Super Sonic covers himself in a blue aura and dashes forward. He stuns opponents in the way.
 * Light Speed Attack: Super Sonic's signature move. It's a hybrid of the Spin Dash and the Light Speed Dash. Super Sonic curls into a ball, and then dashes at all nearby opponents at the speed of light. The only downside to this move is that it costs Sonic 5 Rings to use it.

Hyper Sonic

 * Hyper Flash: Hyper Sonic's signature move. Hyper Sonic dashes through the air and makes the screen flash white. Aside from a double jump, this move would seem inefficient against enemies, though this is not the case. When enemies are onscreen, all of them will instantly be destroyed.

Miles "Tails" Prower
 
 * Propeller Flight: Tails spins his twin tails to take to skies. He can only fly for so long without becoming fatigued, though.
 * Propeller Hovering: This technique was exclusive to Tails in Sonic Adventure 2, only seen by entering a Chao Garden or with the help of a cheating device. The startup of this move is identical to that of his Propeller Flight, but the effect is a bit different. As long as the player holds down the "A" button, Tails can stay in the air as long as wants to. However, he won't rise nor descend as long as "A" is held, so the efficiency of this of the attack varies in different situations.
 * Tails Attack: Tails spins his twin tails in a circle and attack the enemy. availiable in Sonic Adventure.
 * Rapid Tails Attack: Aftef getting the Rhythm Badge, Tails can spin his tails continuously.
 * Thunder Shoot: One of Tails' moves in Sonic Heroes. While in flight formation, Tails surrounds his teammates with electricity and launches them at enemies to stun or destroy them, with enough power.
 * Dummy Rings: Fake power rings that Tails uses to either incapacitate, damage or destroy his enemies when need be. They can be used separately or as bombs.
