Rathian

Rathian is the female counterpart of the Rathalos and also renowned as The Queen of the Wyverns. Rathians are green wyverns that slightly vary from Rathalos in looks and attacks. She has a patch of brown thorns on her upper back and her tail spikes are filled with poison. The Rathian fights on the ground a lot more than the Rathalos, who more often exhibits aerial attacks such as fireballs and claw attacks. They are prized for their rare Plates & Rubies. The Rathian has two other subspecies, the Pink Rathian and Gold Rathian.

In MH3 the Qurupeco is able to call out, attracting one of a number of other creatures. A Rathian is one such creature and can even be summoned during the "Trapping the Trickster" 3 star quest, before the hunter's formal introduction to it. The Rathian in MH3 is somewhat revamped in color, as the scales appear darker than its earlier green scales. She also has notably less spines, or thorns, on her back and wings. When Rathian is low on stamina, she will trip at the end of charges, taunt more, and fire a small puff of flame from her mouth instead of fireballs. She will also set off to either sleep at the nest or prey on an Aptonoth. If she manages to pin down a player and bite them, she will be able to recover enough stamina to stop being hungry.

• A Rathian can be called by a Qurupeco, either in the Deserted Island or Sandy Plains.
• Rathian has more HP than Rathalos in each game other than MH3.
• Rathian and Rathalos will always go after hunters that are carrying their eggs.
• When Rathian attacks an Aptonoth it drops a shiny.
• Rathian's performance in battle becomes poorer when its Rathalos partner is defeated, possibly due to grief.
