Pink Rathian is a Subspecies of the Rathian introduced in Monster Hunter G. It's is known to inhabit temperate and tropical areas and can be encountered at Low, High, and G Ranks.
Pink Rathian has a more heavily-armoured body and has greater health than her green relative. She can often be found in various quests alongside her gender counterpart, the Azure Rathalos.
Her attacks are generally stronger than those of normal Rathian, they are also much faster then its green relative, but that aside the two are identical in many ways.
Other Non-Subspecies Forms
Hard Core (HC) Pink Rathian
HC Pink Rathian has a more purple color to certain parts of its body and more spikes on its tail. It has new behavior and attacks including a fire ball so large and strong it creates an explosion larger than the creature itself, and has a tail swing that instead of turning its body, it waves its tail around behind it poisoning anyone it hits. In G-Rank, it gains a new attack in which it lifts a large boulder from the ground, then destroys it with its talons, sending chunks of rock in multiple directions in the process. It will also shoot spikes from its tail whenever it does its tail spin attack.
A subspecies of Rathian with vibrant pink scales. Pink Rathian wield their toxic tails more skillfully than normal Rathian, using a wide variety of attacks to weaken their prey before eventually moving in for the kill.

Pink Rathian returns, revamped. She is particularly adept at tail-based attacks now, and can be found in the Misty Peaks. Additionally to her new tail-rotation flip she performs a fire bite instead of a normal bite.
