Brachydios

Brachydios are Brute Wyverns introduced in Monster Hunter 3 Ultimate.



Physiology
Brachydios are easily identifiable by their glowing, green slime-covered horns and "fists," as well as their shiny, armored hide covered in many plates and ridges that are made of obsidian. Unlike other Brute Wyverns, Brachydios sports a pair of long, highly developed forelimbs that it uses as its primary means of defense. Brachydios' forelimbs and horn seem to secrete a mysterious slime. According to in-game information, Brachydios "primes" this mucus to explode with its saliva, hence why it licks its arms, making it appear brighter green. Despite initial appearances, Brachydios does possess claws on its forearms that are tucked away underneath, and serve no apparent purpose in battle.

Behavior
By slamming the ground or prey with its fists or horn, Brachydios can deposit a puddle of its slime mold, which, once detached from the monster's body, quickly undergoes a powerful chemical reaction and violently explodes. The substance itself is also sticky; if a hunter is struck directly by one of Brachydios' fist or horn attacks, it will adhere to the hunter's body, and eventually explode. Hunters can remove the substance by rolling or using a Deodorant. Notably, Brachydios is also capable of leaping far distances by using its powerful hind legs and is much more agile than other Brute Wyverns.

When enraged, Brachydios' fists, horn, and various ridges along is body glow a bright yellow and orange. In this state, Brachydios will no longer leave slime puddles, but will instead cause explosions directly on impact with almost all of its horn and fist attacks.

Etymology
Brachydios' name comes from the latin name for arm, brachium(ブラキウム). This was used to make a reference to Brachydios' shell, which is made of obsidian(オブシディアン).

Raging Brachydios


Main Article: Raging Brachydios

The Raging Brachydios is known to inhabit the Ingle Isle. It is an unusual Brachydios individual with abnormal activation of its Slime Mold and the usual Slime Mold on certain parts of its body has become a lot more active than before. The slime that covers it is capable of exploding; this can only occur if the hunter stays in close proximity and if the slime on the Raging Brachydios is glowing bright red. It is also worth mentioning that the slime puddles explode at a noticeably faster rate.
