Fire Combination

Fire Combination is one of the Power Formation manoeuvres used by Team Sonic, Team Dark, Team Rose and Team Chaotix in Sonic Heroes. It is a basic fighting pose that the Power Type character from each team (Knuckles the Echinda, E-123 Omega, Big the Cat and Vector the Crocodile) assumes to perform certain combo attacks with their teammates.

Description
In order to perform the Fire Combination, the selected team must be in Power Formation with the Power Type member as the leader, and at least one other team member must be present.

When performing the Fire Combination, the Power Type member grabs the Speed Type teammate and the Fly Type teammate and begins carrying them around. This is done in gameplay by holding down the Attack button. To break the Fire Combination, the player either has to launch the gathered teammates away or press the Attack button again. Each team's Power Type member carries their teammates in a different manner: In the chase of Team Sonic and Team Dark, using Fire Combination allows both Knuckles and Omega to perform powerful groundbased attack combos, by using their teammates as weapons to punch/slash through enemies. Also, since their teammates are performing the Spin Attack while they rest in each user's hand, Knuckles' and Omega's attack power are greatly amplified. Also, by jumping into the air and holding the Attack button (basically making a Fire Combination in mid-air) will cause Knuckles' and Omega's teammates to rotate around them, damaging anything around them.
 * Team Sonic: Knuckles grabs Sonic and Tails with each of his hands, while Sonic and Tails are curled into spinball form. Once grabbed, Knuckles can carry one team member on each fist, while Sonic and Tails are continuously performing the Spin Attack.
 * Team Dark: Omega grabs Shadow and Rouge with each of his metal claws, while Shadow and Rouge are curled into spinball form. Once grabbed, Omega retracks his hands into his arms, so that Shadow and Rouge, who are continuously performing the Spin Attack, are resting in each of his wrist sockets.
 * Team Rose: Big grabs Amy and Cream with his fishing rod/umbrella, while Amy and Cream are curled into spinball form. Once grabbed, Big makes Amy and Cream sit normally on each of his shoulders while he is carrying them around.
 * Team Chaotix: Vector grabs both Espio and Charmy with his large mouth, while Espio and Charmy are curled into spinball form. Once grabbed, Vector can hold both Espio and Charmy, who are continuously performing the Spin Attack, between his jaws and can carry them around.

In the chase of Team Rose and Team Chaotix, however, the Fire Combination cannot be used by the Power Type character to engage in close, groundbased hand-to-hand combat. Instead, the Fire Combination is used by Big and Vector to gather up their teammates and then launch them as fireballs from long distances to damage enemies and destroy obstacles.

While the Power Type has activated the Fire Combination, the Power Type member can withstand an attack from the enemies without taking damage or losing an active Shield. However, they will get knocked back and have the Fire Combination broken.
