Rathian is the female counterpart of the Rathalos. She is a Flying Wyvern introduced in Monster Hunter and is know to inhabit a wide variety of environments. She can be encountered at low, high, and G-ranks in all currently released games.
Rathian is a medium-sized true flying wyvern similar in looks to her male counterpart, Rathalos. Her hide is a duller and more muted colour, and her lower mandible features a long, protruding chin spike. Her upper back and wingtips are covered in a moss-like fur not seen on the Rathalos, and while her clubbed tail lacks bony spikes, it makes up for this with its ability to poison foes upon contact.
Rathian, like her mate, can produce flaming projectiles from her mouth. She is notably more proficient in the use of this weapon however, as she is commonly seen releasing three blasts at once. In addition, she is capable of charging up and releasing a more potent fire blast which can ignite a swath of ground in front of her. She can use the poisonous barbs on her tail club to inflict blunt-force, toxic wounds on foes. Her powerful legs allow her to run at high speeds, making her easily capable of chasing down most prey.
Rathian is very territorial, choosing to patrol from ground while her Rathalos mate patrols from the sky. She will become very aggressive to potential threats, especially when in close proximity to her nest and young.
Rathians can survive in almost any territory as long as the temperature is right for rearing young and food supplies are plentiful. As a result, she is known to be encountered in a large variety of areas such as the Jungle, Sandy Plains, and Primeval Forest.

Rathian and Rathalos actually have the same base health. However, their resulting health is also calculated by the amount of stars a quest has. This means that the Rathalos will have more health in his own quests (his quests have more stars than Rathian's), but the Rathian and Rathalos will have the same health in the "Double Trouble" and "Mating Season" quests.
When Rathian is low on stamina, her fire breath fails. However, those that are too close to her mouth can still be hurt from the flame.
Rathian's tail attacks will cause the poison status. The attacks that cause this are, by taking a few steps back then jumping into the air in a flip or going directly into the flip while she is in the air.
Even when her tail has been severed, Rathian's back flip attack can still poison hunters.
Rathian is capable of doing an aerial roar like Rathalos, although it is very rare due to her being on the ground most of the time.
Rathian and Rathalos will always go after hunters that are carrying their eggs.
Rathians body structure seems to be thicker than Rathalos in 3rd and 4th gen.
