Rathian is a bipedal green or brown colored dragon like creature and the female counterpart of Rathalos. She is renowned as the ‘Queen of the Wyverns’ or ‘Queen of the Land’ and able to inflict poison damage with her spiked tail. Spikes line her wings and heavy scale like plating adorn her head and cover her back. Unlike Rathalos she will fight on the ground more often and seek out Aptonoth to feed on when exhausted but may be attacked by Great Jaggi if in the same area. Rathian and Rathalos cooperate well together, as it is not uncommon to see the two working together and staking wide territories around their nests. Rathian have what looks like a spike on her chin but it is actually a hollow tube used to feed chewed up meat to her young.
Flames flicker from her mouth any time she opens it and if given the opportunity will pin the hunter to the ground to feed on them inflicting poison damage but a dung bomb in the face will cause her to step back.
