Fire Dunk

Fire Dunk is one of the Power Formation manoeuvres used by Team Sonic in Sonic Heroes. When using this technique, Knuckles the Echidna grabs his teammates Sonic the Hedgehog and Miles "Tails" Prower and fires them as projectiles.

Description
To perform this move, Team Sonic must be in Power Formation with Knuckles as the leader, and at least one other team member must be present.

By entering Fire Combination, Knuckles grabs his teammates while they are in spinball form and then holds them in his large hands while they act as spinning balls. Then, by jumping into mid-air, Knuckles releases Sonic and Tails while they are in spinball form and swats them away (one at a time) in front of him with such force that they turn into fireballs. This allows Knuckles to fire his teammates as destructive projectiles to destroy enemies, break down doors and other obstacles from above. However, if both team members are not present when this technique is used, it will fail.

To perform this technique in gameplay, the player has to hold the Attack button to enter Fire Combination. Once entered, the player has to press the Jump button while aiming at the target, and then press the Attack button to fire the team mates.
