Fire Phoenix is the base of Rescue Fire. It's designs are very similar to Rescue Pheonix. Rescue Fire would sometimes use it for space missions. Fire Pheonix is located in Tateishi City like Recue Pheonix.
Unlike Rescue Pheonix, Fire Pheonix has a Final Rescue it could do on its own. Under the command of a Rescue Megaphone, Fire Pheonix can use its move, Freezing Cannon (the Final Rescue Rescue Max and Rescue Pheonix did together was also called Freezing Cannon), freezing the target with twin ice spheres from its wings. Then it finishes off the enemy, ramming with a Pheonix Blast.
