Disclaimer: This is merely a plausible explanation for the monster(s) in this article, and should not be considered canon.

Taxonomy
Doboruberuku is classified as a Brute Wyvern. Alongside monsters such as Barroth, Uragaan, and Deviljho. It's unknown, however, where this monster falls within this class.

Habitat
This Brute Wyvern seems to thrive in the Mountain Stream, although it has occasionally been seen in the Flooded Forest as well.

Ecological Niche
The few teeth Doboruberuku has are flattened and suited better for grinding than they are for tearing, implying that it is a herbivore; its intro video confirms this by showing it eating part of a tree trunk it felled using its tail. It is obvious that it is able to protect itself, although it is unknown if it is territorial and attacks monsters around it. The only monsters that would be capable of challenging this behemoth would have to be large Wyverns, such as Jinouga, or a Deviljho, although as Doboruberuku is herbivorous, it would seem unlikely that these monsters would bother confronting it.

Biological Adaptations
Doboruberuku uses its massive tail to fend off any large predator roaming in the area and can also use it to fell the trees that it eats. It uses its horns to fight off any threat it cannot hit with its tail, charging in a similar manner to Barroth when it does so. Their horns somewhat resemble those of a Diablos. Their shells are seemingly very hard, giving it more protection at the expense of speed. The armored body and clubbed tail is very similar to that of an Ankylosaurus. They are noted for being slow to transition between actions and to store nutrients in their humps. It likely does not move, and due to its seemingly slow metabolism, it might hibernate, but this is still unproven. Plants growing on its back give them the perfect camouflage to disguise themselves from top predators like the Rathian, Rathalos, Nargacuga and Jinouga; this is enhanced further by its habit of lying on its side when asleep, making it appear exactly like a fallen log to the untrained eye. When it swings its tail fast enough, the resulting momentum is enough to allow Doboruberuku to fling itself into the air for a flying slam attack.

Behavior
It may be territorial to smaller monsters like Great Jaggi, Qurupeco, Bullfango and Bulldrome, and Aoashira. It probably, however, prefers to not run into other large monsters like the Rathian, Rathalos, Nargacuga and the Jinouga. It is unknown how the Doboruberuku would react if it encountered another monster (Larger monsters might not see the Doboruberuku due to its camouflage). It seems to shows aggression towards hunters. Its attacks are quite heavy, but it has a slow recovery rate from each attack. When enraged, it will produce white gas from its humps.
