User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-5460283-20121231043936/@comment-4563270-20121231061604

hmmm i'm not sure about the bacteria part. my theory for guran was similar to all my other theories of lava based monsters in monster hunter except the nomads. my theory is that the internal temperature of all volcanic monsters is severely low allowing them to live in such hot places and with hard armored bodies they can withstand disintegration which is why crimson fatalis armors itself. as for guran my theory was that on top of a low internal temperature he has a vein system to trap in geothermal heat and gas similar to a cooling pipeline system except in his case its a heating system with the ability to bleed out any excess of heat through volcanic looking poors. if you look on his body their are little pockets similar to chakra points where magma is constantly swirling and concentrating.

i also theorized that he can biologically produce natural gases on his own to facilitate the meteor attacks and fireballs through his mouth (think how to train your dragon) and is likely his own little mini volcano in a sense which is why the land and sky where you fight him near the city is scarred. in order to adapt he likely taps into geothermal pockets via land or water through volcanoes and reofrms the terra to support himself for a a long or short time which would explain why when he's weak he runs back to the water.. he's probably looking for the thermal pocket that led him to the city in the first place because the hunter damaged his heating system.
