Sonic the Hedgehog

Basic Attacks

Basic combo consisting of two punches and a kick.

Sonic leans on the ground and kicks back using both of his legs.

A spinning upward kick.

A leg sweep.

Dash Attacks

Sonic will roll towards the opponent and land a kick.

Smash Attacks

Sonic will wind up his arm and deliver a heavy, short-ranged punch.

Sonic will jump while rolling, dealing multi-hit damage to the opponent caught near his trajectory.

Sonic will split, hitting any enemy nearby on both sides.

Special Attacks

Sonic will turn into a fast-spinning ball and homes in to an opponent. If it connects, the opponent will suffer good damage and will be thrown. If not, Sonic will land on the ground and bounce.

Sonic will turn into a fast-spinning ball and you can control where he'll go. This move can be chained together with Homing Attack or Spring Jump, which gives you more control and recovery even if Sonic overshoots from the stage.

Sonic jumps over a spring. When used on the ground, the spring will stay a bit which can be used by any player. When used in mid-air, the spring will deal minor damage to anyone it will fell unto.

Sonic rolls forward. Keep pressing down Special to charge up this attack. When released, Sonic will charge in a straight line forward. Like Spin Dash, this move can chain to Homing Attack or Spring Jump.

Air Attacks

Sonic spins around in mid-air

A spinning forward headbutt

A standard back kick

An upside-down scissor kick

A diagonal dive kick

Final Smash

Super Sonic

Sonic transforms to Super Sonic. He can fly and damage any opponent hit while flying. The initial blast from the transformation deals good damage to any opponent nearby. Unfortunately, Super Sonic can't pass through platforms and obstacles so this move can be truly effective in open stages or form versions of most stages.

Recovery

Sonic's main recovery tool is Spring Jump, which has very high jump height. He can connect Spring Jump after using his other spin specials but he can't use them the other way around. Spin Charge and Spin Charge can be used as recovery as well but they're quite risky since Sonic might bounce off the edge and fall to his destruction if the attack connects while the opponent is standing near the edge. Homing Attack can be used as well but since it depends on the opponent's position and distance, recovering back to the stage may be affected by a number of risky factors. Sonic's weight allows his double-jump cover a good horizontal distance. Use that as your primary horizontal recovery method instead.

Gameplay

Sonic is considered the fastest character in the game and it shows how agile his movement speed is. His set of special attacks further augments his speed and can be chained together with little transition delay/animation. Homing Attack is best used when you're within the stage and while in mid-air. If the attack connects, you can immediately execute Spin Dash while the opponent is thrown helplessly from the Homing Attack's impact. Spring Jump is an excellent recovery tool which allows Sonic to use normal aerial attacks (not Specials). Sonic's Smash attacks have limited range and moderate power as well. To excel against opponents, Sonic needs to harness his speed and use that to his advantage. His specials will be the main means to deal damage while the normal ground or air attacks are used to defend himself or dish out small damage at a time. Sonic doesn't have any projectile attacks but he surely doesn't need any since he can quickly cut the distance between him and his target.
