Fire Rodan

When a choir of psychic girls sang a song to BabyGodzilla, the creature that hatched from the egg found in Rodan's nest, Rodan heard it all the way back on Adonoa Island. Rodan was revived as Fire Rodan (ファイヤーラドン Faiyā Radon) and immediately flew to Japan to rescue his surrogate brother. When Fire Rodan arrived, BabyGodzilla was being airlifted via helicopter to the Ogasawara Island, where G-Force hoped to lure Godzilla so he could be killed by Mechagodzilla. Fire Rodan intercepted the chopper while it was still flying over Japan, destroying it and grabbing the canister holding BabyGodzilla and his surrogate human mother Azusa Gojo. Fire Rodan touched down in a nearby city and attempted to break open the canister with his beak. G-Force deployed Mechagodzilla and the Garuda to defeat Fire Rodan. Fire Rodan took flight and managed to bring down the Garuda by slamming his chest spikes into it, sending it crashing into a nearby building. Fire Rodan turned his attention to Mechagodzilla, firing his new uranium heat beam at the mecha and attacking it up close with his beak. Fire Rodan managed to destroy Mechagodzilla's right eye with his beak, but Mechagodzilla used the plasma it had absorbed from Fire Rodan's beam to blast him with its plasma grenade, shredding Rodan's chest and sending him flying into several buildings.

With Fire Rodan seemingly dead, Godzilla unexpectedly appeared in the city and engaged Mechagodzilla in battle. Mechagodzilla combined with the Garuda to form Super Mechagodzilla, and crippled Godzilla by destroying his secondary brain with its G-Crusher system. At this point, BabyGodzilla broke free of the canister and cried out, gaining the attention of the wounded Fire Rodan. Fire Rodan took flight, only to be shot down by Super Mechagodzilla's mega buster. Fire Rodan fell on top of Godzilla, and began transferring his life force into him. As Fire Rodan faded away, Godzilla's secondary brain was regenerated, and he rose back to his feet. Empowered by Fire Rodan's energy, Godzilla destroyed Super Mechagodzilla and left Japan with BabyGodzilla.
