Monster hunter theory explanation- Brachydios- Brachydios is one of monster bunter's weirdest animals. It face, arms and head are relatively new and even classified as odd. The slime on its arms explode when touched. How does this actually work? Well, in my opinion the Brachydios is able to manipulate this action just like a human moving his arm. This however does not explain the brachidios's ability. This is where my second part comes in, The brachidios's arm has flammable material (like TNT, gunpowder and oil) however the flammable material is not enough to cause an explosion. This is where it's environment comes in, the Brachydios lives in the volcano and the tundra which have a source of heat. Many people would say that a tundra is a cold place so how will a Brachydios cause ignition? Well, the layer underneath the snow is heated to around 30 degrees within a feet below the snow where as the volcano is hot but the rock is hard for a detonation considering using no fire as detonation. This is where it's "handy" hand comes into use. The slime penetrates rock allowing contact to free flowing lava as an ignition. The lava is not actually used but the heat is necessary to cause the ignition. This also applies to the tundra however ignition is much quicker as ice is not as thick or anywhere near as thick as stone. The slime on its head is used for ignition as it charges, due to the fact that animals and humans have body heat. The "crest" on its head is too weak to withstand ground impact. Another, more acceptable , hypothesis is that the slime aforementioned several times could be acid as acid can penetrate both snow and rock easier than many other flammable materials.

Arms? Isn't a typical brute wyvern arm small? Yes, however Brachydios arm is used to deploy acid even still the arm is smaller than the leg.

Why is the head shaped weirdly ? Possibly to provide a stronger bite force killing heavily armoured apceros with ease thus extending its diet. Or it could be used as a "lance" to keep intruders out of their territory ( the portion of the head the sticks out bother the acid carrying crest which is used to have more flexibility in its attack choices).

We have come to an end to my thoughts. This may not be canon as most of the ideas are mere predictions.
