Akura Vashimu

The Akura Vashimu is a scorpion-like carapaceon that is thus far exclusive to Monster Hunter Frontier. The Akura Vashimu has blue-purple crystals growing on its claws, back, and tail tip. It has a huge geode mineral on its tail tip that shoots out a high-pressure poison at its enemies, causing them to be semi-frozen (like the Snowman effect) and lose all stamina (like the Chameleos gas effect). The Akura rests and hides underground, protruding its large mineral tail tip on the surface. If it is aware of nearby enemies, its tail breaks out of the sand and swings around violently, hurting anything nearby. It is possible to temporarily break the tail crystal, but the geode will slowly grow back during the battle as a small geode. Its attack pattern and breakable parts may depend on its colour (grey ,red, green, blue) but if it's red, then it will signify that Akura Vashimu is near death.

How to cut Akura Vashimu's tail
Unlike Elder Dragons, where their health must be below a certain level before the tail can be cut, Akura Vashimu is quite different. First, it needs to be in other colours to break the geode with an Impact weapon (Hammer is probably the best here). After the Geode is broken, Akura Vashimu has to be in blue mode to actually cut the tail with a cutting weapon. This yields an unknown number of carves. Akura Vashima is unique in that it will eat it's own tail in order to regain it. However, it will not do this if the tail has been carved.

Carapaceon Relations
There has been much speculation over whether or not Akura Vashimu and its relative Akura Jedia are Neopterans or Carapaceons. But there have been recent studies and psychic imaging using the autotracker skill does indeed prove that these monsters are carapaceons (Albeight highly evolved species of carapaceons, which has granted them the title of the Embodiment of Evolution.). These studies along with some of their natural carapaceon like habits proves and cements them in a special Carapaceon Family of their own, the Akurids.
