When performing the Blue Tornado, Sonic uses the Spin Dash to circle around an opponent in midair at high speed while leaving a blue aura trail. The resulting slipstream creates a tornado effect that forms a blue cyclonic vortex of air around the opponent.
The effect of the Blue Tornado depends on the type of enemy it is used on. If used on unprotected Egg Pawns, Egg Knights or opposing playable teams, the Blue Tornado sucks the opponents off their feet and flings them into the air, before they fall back down to the ground. Upon landing, they will take damage and be potentially stunned for a short time - for someenemies, this can even reveal their weak spots. If used on Egg Pawns or Egg Knights wearing shields, the Blue Tornado will permanently blow off their shields, thus leaving them with a weaker defense. If used on larger or airborne enemies, the Blue Tornado will make them disorientated at most, but will deal no damage.
Besides affecting enemies, the Blue Tornado can also be used in conjunction with some of the gimmicks in Sonic Heroes, such as enabling the player to scale Poles or activate propellers.
To perform the Blue Tornado in gameplay, Team Sonic must be in Speed Formation with Sonic as the leader. The player has to press the action button (//) during a jump to use the Blue Tornado. When using this attack, Sonic will automatically home in on the nearest enemy within a reasonable distance to use it on. Unlike the Homing Attack, the Blue Tornado will also home in on enemies above Sonic.
The Blue Tornado allows for an additional height boost if the player holds down // during or after the move. This essentially allows for a double jump.
While airborne enemies are affected by the Blue Tornado, they become temporarily invulnerable.
In Sonic Rush, Sonic uses a move similar to the Blue Tornado as his special attack when Blaze fights him during the Dead Line boss fight. Here, however, this tornado sucks Blaze in from the outside, rather than throw her upwards from the inside.
This attack could be a variation of the Sonic Wind.
