In Godzilla: King of the Monsters (2019), they didn't explain Rodan's origin too well. Gidorha's origin was explained to be an extraterrestrial. Though Rodan was hibernating in the volcano, he barely had any special attributes like Godzilla having an atomic breath or Mothra being able to shoot silk. Coming from a volcano, you would think he'd have fire breath at least. What are Rodan's origins and special powers?
In King Of The Monsters, Rodan was awakened by an accumulation of volcanic gas. Rodan's origin goes back to the 1956 film Rodan, when he was a Pteranodon that lived deep underground and was mutated from exposure to radiation, and grew to gigantic size.
Rodan possesses several abilities, including:
Durability - Rodan is the only monster not affected by Godzilla's atomic breath.
Flight Speed - Rodan can avoid attacks by flying away from them.
Wind/Radioactive Heat Breath (not used in this movie) - In Rodan's first movie, he could emit a beam of wind to knock opponents down. After that first movie, the wind was changed to a radioactive blast of heat.
Thunderclap - Rodan, specific to King Of The Monsters, can generate a tremendous amount of wind by flapping it's wings in the direction of an enemy.
