Unknown

Unknown appeared in 2011 video game called Monster Hunter Frontier Forward.1. Unknown is a mysterious species of Flying Wyvern introduced in Monster Hunter Frontier Forward.1.

Unknown superficially resemble the Old World species of Rathian, but with very noticeable differences. Its color scheme is mostly black and dark grey with its talons, wing claws, most of its tail spikes, and some parts of its back plating being a crimson red. Its wing claws are long and have a downward curve, and its tail club has a few small spikes lining both sides, and culminating in a larger reddish orange spike tipping it. Unknown notably has more than one enraged state most of them changing its appearance a bit.

In its first state it starts huffing black smoke.

In the next changing state it starts huffing blue and yellow flames.

And in the final state crimson red flame patterns appear on its wing membranes as its eyes turn a glowing crimson red.

Despite their hostile appearances and infamously destructive tempers Unknown are actually rather peaceful when calm and somewhat sluggish, at least until something threatens them, attacks them, or they see said thing as food, by that point their ferocity and true strength shows itself. Unknown are also known to gather in large numbers in arid deserts during certain seasons for unknown reasons.

Unknown have been spotted living in ruinous areas like the Tower, flora filled areas like the Great Forest, and arid areas like the Desert.

Powers and Abilities
Unknown have numerous abilities that make them incredibly dangerous opponents. They are fast and very powerful, can breath spheres and beams of flame in various ways, have venomous talons that are also strong enough to tear chunks out of the ground and crush them, they can throw their wing claws as potent projectiles which regrow in little time, and can even release a short ranged corrosive gas cloud. But their most infamous ability is their tempers. The angrier they get the faster and stronger they get, with their bodies changing in accordance. Unknown will also do large sidesteps to reposition themselves and momentarily get out of most hunters range.

There have even been reports of Unknown able to create enormous pitch black clouds of gas to obscure their opponents vision leaving them wide open for attack.
