"Personality variants Tigrex are fairly violent and aggressive. The Tigrex's developed using a limb, claws and jaws to deal powerful blow to all its adversaries, which must be noted that the Tigrex is the greatest danger to all hunters"
Order:Saurischia- Suborder:Dragon Feet- Family:Rex. The Tigrex Subspecies is a Quadrupedal Wyvern. It has few differences from the normal variation, other than coloration and habitat. Some of its differences include its habitat of preference, Volcanoes, which contrasts to that of the regular Tigrex (which inhabits the Snowy Mountains and Tundra). Despite these differing adaptations, both species are able to survive in the Sandy Plains.
This dark-colored wyvern is found exclusively in volcanic and Desert areas, which would imply that the Tigrex Subspecies is better suited to much hotter environments than the normal Tigrex. It has also adapted its pattern of attacks to better utilize its surroundings, like its thrust, which will send waves of magma that cause fireblight. It can also use strata from the volcanic grounds as hurling stones. As it is capable of charging through lava, as its scales have adapted to be resistant to the extreme heat of lava.
Tigrex Subspecies' role as a top predator is no different than that of Tigrex. Its only known competitors include Agnaktor, Rathalos, Brachydios, Stygian Zinogre and Deviljho (which occasionally ventures into the volcano); although, that being said, the monsters above can present quite a fight if encountered. A fully-grown Uragaan or Steel Uragaan may also present a threat to a Tigrex Subspecies, although a confrontation between the two would seem unlikely, due to the lack of competition between them. In the Sandy Plains it must also compete with the normal Tigrex, Sand Barioth, and Nibelsnarf. They also live alongside the highly aggressive Diablos. Due to its ferocity, speed, and power it would probably be able to defeat or drive off most of these opponents, although, due to the risk of injury, it prefers to leave them alone, and the reverse is also true.It is heavily territorial, attacking anything that it has set in sight its boundary. Unlike the Tigrex, the subspecies doesn't seem to travel to subarctic areas to prey on the surplus Popo, so it is rather resourceful with its environment, and preserves it's food suplies better than it's more common cousin. It may hunt Rhenoplos, Volvidon, Slagtoth, Uroktor, and the Wroggi and Great Wroggi that live in the lower levels of the Volcano. Since food is scarce in the volcano, the Tigrex Subspecies may occasionally be forced to prey on immature Uragaan, or other large prey, but it is most likely that it would just establish a new territorial range should this problem arise.
Just as Tigrex has coloration suited to both tropical sandy deserts and freezing snowy landscape, the Tigrex Subspecies has just the right coloration to blend in with the Volcano's cliffs and crevices. It is confirmed that this altered coloration is the result of extreme heat causing volcanic ash and other such impurities to fuse to the Tigrex's shell. However, the presence of this ash seems to make its shell less effective at insulating heat, leaving the Tigrex Subspecies vulnerable to cold temperatures as well as ice-based weaponry.
Much like normal Tigrex, these Wyverns are powerful in every sense of the word. Unlike normal Tigrex, this subspecies is not as commonly found in the Tundra, being most commonly found in the Volcano but the Tigrex Subspecies can also be found in the Sandy Plains, but rarely.
Tigrex Subspecies appear much more aggressive and more maniacal in attacking in comparison to Tigrex.
Being extremely aggressive, it will even challenge, and possibly kill, a Rathalos if confronted or challenged for territory. It will fiercely attack hunters on sight. It is also quite stubborn, recklessly attacking like a stampede, even when it's extremely wounded by its foe. It would appear that it is more intelligent in attacking than its normal counterpart, making it quite a challenge to hunters. The heat of the volcanic region might contribute to its reckless behaviour, as the heat would allow it to maintain its body temperature without wasting its own energy doing so.
