Things you may not know about the Fatalis and Diablos(Info comes from MHF1, MHFU, MHP2G, MHP3, MH3U, MH4, wikiwiki.jp, atwiki.jp) Fatalis

Firstly, its title, in multiple different regions, are different from each other.

Fatalis threatens the lives of all living things, including Lao-Shan Lung and possibly other giant monsters.

The Fatalis is one of the few monsters able to affect the world. Fatalis could scorch the whole world with its flame in a few days, in other words Fatalis could possibly burn areas to a crisp with its powerful fire and destroy major ecosystems and, affecting the planet(This seems more likely with MH4's Fatalis and that new Fatalis).

Since the Fatalis is only detailed in legends and fairy tails, it is detailed as an imaginary monster. Info on it is very little and from this is its only pictured on icons as a "?"since no real things have been found on it.

Recently, they have found the Fatalis in MH4 and it seems their either an older individual/some type of mutation of the Fatalis but with powerful fiery attacks.

According to ancient documents, Fatalis brings its prey/victums back to its lair before taking the armor of them and melting it on their scales for their powerful armored hide. It also does this to hunters and soldiers.

The Fatalis' scales are extremely thick while its hide is very heavy and hard.

The Fatalis' eyeballs are made of crystals(I'm both shocked and speechless).

A Fatalis' wing membrane is flexible but also as hard metal though breaking it wings aren't very easy.

Diablos

Firstly, Diablos numbers are much higher than Monoblos numbers. Its even comparable to most other Wyvern numbers.

Female Diablos grow larger than male Diablos(This means that the large Diablos we kill are most likely female).

Diablos are extremely territorial and can cause a lot damage. They have even attacked whole groups of soliders and nearly/even destroyed a few barriers that were made. This aggression can even go to their own species, including with their own mate or young, but this is most commonly seen by males protecting their turf.

One swipe of their tail is much stronger than a Steel Hammer.

Diablos have better adapted hearing but their vision is poor.

The black smoke that comes out of their mouth seems to be a gas from one of their organs.

Their are rumors of Crimson Diablos in the Desert that are mutations as soon as they are born. They are larger than a normal Diablos and they have been said to have be faster and stronger than a normal Diablos. It is said that this mutation could be a Diablos that has gone mad and has turned red due to blood from enemies.

The Black Diablos' color is a warning color.

They aren't very caring like Nono and the Rathian towards their mates.

They stick to territory more often than usual and it seems the males come looking for them.

Diablos Hearts are in high demand like Monoblos Hearts for food.
