Yama Kurai is an Origin Species of Yama Tsukami, first introduced in Monster Hunter Frontier G8.


Yama Kurai are close relatives of Yama Tsukami and as such bare resemblance to them. Their bodies are overall bushier in appearance with hooked claws present on their whiskers and tentacles, large stained yellow teeth, and underbellies with several large spines. When desperate their upper bodies change color from green to orange.


Due to the gases produced within their bodies Yama Kurai are capable of floating through the air. Numerous plants and special seeds grow on their bodies in a similar symbiotic relationship to the Great Thunderbugs that also inhabit them and attack threats, shaking the seeds off they essentially act as land mines for any hunters that wander near. They are also toxic and can release large clouds of varying types of poisons to wear down opponents or even inhale hunters right into them. Lastly they are capable of creating large whirlwinds which chip away at the health of hunters who stand in them.


Yama Kurai are extremely dangerous and are best avoided. They are more aggressive than Yama Tsukami in addition to the usual threat of being sucked up while they are feeding.


While they are known to wander to many types of places they are most commonly sighted in the Highland.
