When the two Rodans were born, one joined Godzilla and was mutated by him, becoming Fire Rodan. This is what happened to the other one: he joined Korean Godzilla, who later accidentally mutated him into Ice Rodan by using his Nuclear Pulse on him. When his wings are fully spread out, they are 150 meters, and he is 70 meters from the tip of his beak to his feet. Ice Rodan can absorb nearby small animals into his body to restore some health, can instill energy in others by sacrificing himself, fly at mach 19, and fire an extremely cold nitrogen beam from his mouth.
