Alatreon Ecology

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

In-Game Infomation
Blazing black dragons, so named for resembling both lightning and darkness. They mercilessly tear apart whoever touches their sharp scales. Elementally unstable, their actions can affect the very weather. Living natural disasters.

Taxonomy
An Elder Dragon; it is quite possible that Alatreon is from the same ancestral line from that of the Kushala Daora. Sharing the same body shape and its extremely good flying abilities, the Kushala Daora seems to be the closest living relative to the Alatreon.

Habitat Range
Alatreon is only fought in the Sacred Lands, an area within the Volcano. It presumably has access to any point within the Volcano when it hunts for food or a mate, and it may even venture beyond the volcano at times, but there is no evidence to support this.

Ecological Niche
Alatreon is one of the most feared monsters, and is at the top of the food chain. Whilst very young or unexperienced Alatreon are at risk from Agnaktor, Deviljho or Rathalos, the adult form fears almost nothing, save large Deviljho and other Alatreon. Only a few monsters can hope to defeat an adult Alatreon, and the few monsters that might defeat it (like Fatalis) live far away from Alatreon.

Biological Adaptations
Known as the "Glittering Black Dragon" Alatreon possesses control over the Dragon, Fire, Thunder, and Ice elements, and is said to be elementally unstable. The large horns atop its head are very powerful and make for a lethal weapon, although they are at risk of getting caught in the surroundings. Alatreon is an adept flier, and can attack prey from the air. Another note is that when it goes into rage mode, not only does it glow, it releases energy in the form of whatever move it has used or it will use. For example, when it does an electrical attack it will huff little lightning bolts, and when it uses a fire move it will huff flames.

Behavior
Alatreon is aggressive towards hunters and prey, but not overly so. It may be considerably more aggressive when caring for young (if indeed it does), yet more relaxed around a partner. After mating, the male may leave its mate, leaving the female to raise its young alone. This would explain why hunters never fight more than one Alatreon at the same time. An adult Alatreon may be very territorial. This may be the reason why no other animals live in the Sacred Land. Alatreon might attack most of its prey from the air, giving it an advantage over most other monsters. When an adult Alatreon is searching for a mate, the males will battle each other fiercely. If the Alatreon loses, it will either die or flee away from the other male to recover from its injuries, but will have to wait a while to find another mate.
