Behemoth Ecology

In-Game Informaion
"A powerful beast from another world. Its large horns and muscular frame defy nature. Unique strategies are required to battle it"

-Monster Field Guide, Monster Hunter: World.

Taxonomy
While it bears a physique similar to some Fanged Wyverns like Zinogre, Behemoth never belonged to any biosphere of the known world and thus does not fall under conventional Taxonomy. However, its power easily had it defined as Elder Dragon by the Guild.

Habitat Range
Behemoth came from an entirely different world of Eozra and thus does not consider any habitat charted by the Guild its home. The Elder's Recess of the New World is the only locale the monster was ever known to prowl, mostly because it is the site of its entry from the anomalous occurrence that brought some Eorzean creatures into the continent.

Ecological Niche
In its home world, Behemoth is already considered a powerful creature, often requiring the effort of a dozen or more heroes with various unique and magical abilities. When it arrived in the Elder's Recess, it easily asserted itself as an unrivaled invader that could easily kill lesser monsters like Dodogama with no effort and deter those fortunate enough to flee. Apparently, even Elder Dragons like Nergigante, Teostra and Kushala Daora are reluctant to be in the Elder's Recess during the beast's time there. Behemoth thus made itself a threat to all life in the New World, so much in fact that the Commission deemed made it a priority target. It is almost a mandate for any hunter not to tackle the creature alone, a degree of caution reserved by the Guild for very few creatures.

Biological Adaptation
Behemoth has a proportion of size, weight and speed that can easily be described as nature-defying. The creature is almost as big as the recently discovered Xeno'jiiva, although it could move as fast as Nergigante. It also has powerful horns and claws that while seemingly have no special attribute to them, prove to be dangerous weapons when paired with their very muscular build. The combination of these physical traits allows Behemoth to pull quick and powerful attacks that covers a wide area in a continuous streak; one reason why fighting the monster alone is heavily advised against.

Behemoth also has the ability to cast magical attacks that is rather unnatural even compared to Elder Dragons. While fellow Elder Dragons commonly generate, conduct or manipulate a specific substance or energy to produce powerful effects, Behemoth seemingly conjure natural disasters out of thin air: It can summon meteors, make whirlwind to appear in a specific spot, make lighting strikes and most infamously, summon a titanic mass of rock from the sky to easily destroy would be-opponents, a move called "Ecliptic Meteor". However the Ecliptic Meteor seems to be very self-destructive towards Behemoth itself, as they can die from using it too often or in heavily wounded state.

Another unique trait of Behemoth is its ability to develop "Enmity" towards a foe, which basically makes Behemoth more focused and determined in a fight. However, it is a double-edged sword as in this state, Behemoth could not heed proper attention to multiple opponent, making it vulnerable to flanking attacks.

Behavior
Either shocked for being transported into a different world or because of its natural traits, Behemoth shows no tolerance towards Hunters, and will show almost immediate aggression, possibly because the creature also bears terrible relations with humanoids back in its original world. Little else is known of the creature's behavior.
