One of the most recognized monsters, Rathian are a part of the Flying Wyvern classification along with their male counterparts, the Rathalos. There are three known species of Rathian: The Old World Species, New World Species, and Val Harbar Species. There is also two genetic mutations of the Rathian, the Pink Rathian and the Gold Rathian.
Rathian of the Old World are seen inhabiting the Forest and Hills, both Swamps, both Deserts, both Jungles, Gorge, Highland, Great Forest, Ancestral Steppe, Sunken Hollow, Everwood, Heaven's Mount, Dunes, Primal Forest, Misty Peaks, Ruined Ridge and Tower. New World Rathian are seen inhabiting the Deserted Island, Sandy Plains and Flooded Forest.
Rathian are high in the food chain. They feed on herbivores, like Kelbi and Aptonoth, and lesser predators, like Velociprey and Jaggi. While being powerful predators themselves Rathian compete with other fearsome creatures such as Tigrex, Zinogre, Seregios, Plesioth, Espinas, Gore Magala, Najarala, Ivory Lagiacrus, and Deviljho.
Rathian stands in the top of several food chains in the New World, being the female counterpart of the apex Rathalos. However, some monsters like Anjanath are less inclined to back off against Rathian then they are against Rathalos, which the female wyvern is not unprepared to face, especially when it concerns the safety of her nest. Diablos of the Wildspire Waste are one of the few monsters that could pose a threat to Rathian beside Elder Dragons and invasive monsters.
Rathian have a poisonous tail, but lack the poisonous claws of the male wyvern. They instead have developed poisonous barbs that deter most attackers. The roar of a Rathian is just as fierce as that of a Rathalos and its land-based maneuverability is even greater. Both Rathian and Rathalos have a spike protruding from their chin, but it grows much larger and sharper on Rathian, making their tackle attack even more dangerous for wyverns and hunters alike. Rathian have the ability to perform backflips to knock a foe out of its way while simultaneously poisoning them. Even if a hunter was to sever a Rathian's tail, her backflip attack would still poison the hunter, suggesting that the poison-producing organ is near the base of the tail or near the flame organ.
Depending on the region, Rathian can vary greatly from each other. This is due to there being a few different subspecies of Rathian found throughout the world. The three known ones are the Old World, New World, and Val Habar species.
Some rare individual Rathian of the Old World have grown a larger amount of poison spikes on their backs, wings and tails along with purplish claws. Other rare individuals also develop a unique flame sac and use a new technique allowing their fireballs to scatter on impact.
Rathians are very territorial, choosing to patrol from ground while her male counterpart patrols from the sky. It will become very aggressive to potential threats, especially when it is taking care of its young.
