This will be the first incarnation of Rodan to appear in an American-made film.
Rodan's Japanese name, Radon, is a truncation of "Pteranodon." It may also have been chosen to suggest radiation. The name was changed to "Rodan" in English-speaking markets, possibly to avoid confusion with the element Radon. Toho eventually trademarked the name "Rodan," making it the monster's official English name. According to Monarch, Rodan is referred to in some legends as the "Fire Demon" and "The One Born of Fire." 
The MonsterVerse Rodan is a giant pterosaur-like creature with a large beak, two horns protruding from the back of his head, and huge wings with molten rock trailing off their edges. His body is a burgundy red color, while his beak is black. Rodan has a very large, flat, fan-shaped tail.
Rodan's origins are unclear, but he is presumably an ancient creature, due to being depicted in what appears to be an ancient cave painting. Similar paintings exist of Godzilla, Mothra and King Ghidorah, suggesting Rodan either appeared alongside them in the past or is prophesied to appear alongside them in the future. According to Monarch, Rodan is spoken of in legends, with his name referenced within many ancient temples in volcanically active regions. In 1991, Rodan was discovered by Monarch in pyrostasis in the magma inside the Isla de Mara volcano in Mexico.
After their adventure on Skull Island, Monarch members Houston Brooks and Lin San showed James Conrad and Mason Weaver a cave painting of Rodan, along with paintings depicting Godzilla, Mothra and King Ghidorah, as proof that the inhabitants of Skull Island were not the only monsters in the world.
Rodan can fly at sufficient speeds to outmaneuver fighter jets.
Rodan produces destructive shockwaves while flying which can flatten buildings he passes over. Monarch scientists speculate the monster's wingspan is vast enough to level cities with this technique.
Rodan has an extreme tolerance to heat and magma, having hibernated inside a volcano for at least several decades.
Rodan has an internal combustion system of magma that flows throughout his body.
