Rescue the Mach Train!Edit
In the movie, Reiji Osakabe (R0) summoned Zero Fire out of the canyons. Then it launched the five medium vehicles to remove the busts on Mach Train's track. Later, R0 and Zero Fire aided Super Rescue Max against Dr. Mado's Snake Train.
In the series, Zero Fire and Resue Zamber were planned for creation. When Zero Fire was completed, R5 piloted it to help battle against the last Zukkien. While Dozer, Drill, and Shovel freed the concrete-encased Super Rescue Max Crane, Zero Fire, Riser and Turbo fought against the Zukkien until SRMC scrapped it
In episode 7 of Rescue Fire, Zero Fire carried the medium-sized vehicles to dock so they could be transferred to Europe. While the vehicles were being loaded, Zero Fire's cab could be seen in the background.
