The Fireball is a Power Formation maneuver and the Remote Power Attack used by Team Chaotix in Sonic Heroes. When using this technique, Vector the Crocodile fires his teammates Espio the Chameleon and Charmy Bee as projectiles from the ground.
When performing the Fireball, Vector, having entered Fire Combination, bends back and spits out one of his teammates in his mouth at his targets as spinning balls with such force that the teammate turns in a destructive fireball. This allows the player to damage enemies, break down doors and destroy other obstacles that can be on both the ground and in midair from afar.
To perform this technique in gameplay, the player must have Team Chaotix in Power Formation with Vector as the leader. The player then has to enter Fire Combination and press the action button (//) to fire the teammates. When used near targets, the thrown teammates will automatically home in on them. Additionally, the Fireball can be used up to two times in a row, depending on the number of teammates Vector carries.
