Rathalos are medium to large-sized flying wyverns, with their most notable features being their crimson appearance and huge fire patterned wings. Rathalos inhabit many areas; they are most commonly found in the Forest & Hills, along with the Volcanic zone and the Swamp zone. In Monster Hunter 3 they can be found in the Volcano and Deserted Island. Rathalos spend most of their time fighting while airborne. This ability to live in the strangest and harshest of climates makes the Rathalos renowned far and wide as the King of the Wyverns.
