Barioth are one of the monsters who are seated at the end of the food chain in their icy domain. They are very agile yet they hit hard at the same time. They ambush Popo, Anteka, Pokara or Lagombi, who have protein-rich meat under their thick hides. Barioth prefer eating the internal organs of their prey. The only other competitors who have the capacity to defeat a Barioth are Stygian Zinogre, Brachydios, Anorupatisu, Giaorugu, Tigrex, and Glacial Agnaktor. Gigginox and Baleful Gigginox are also a threat.
Barioth are accustomed to the Tundra and the polar regions. Their pelts, which are colored pure white, provide camouflage that easily allows them to ambush prey, or even top predators, in the blinding snow. They are in possession of extremely sharp front canines which could pierce through the hides of Popo like soft butter, causing them to bleed readily after the large wound. They have razor-sharp claws which would deal heavy damage to even a foe like Glacial Agnaktor, and could mince anything in a few slices. Those claws and its spikes also aid Barioth in scaling slippery, steep ice canyons and walls, or glaciers. Its squinted eyes are suited to compensate the glare created by the snow's reflection during the day where sunlight reaches the Tundra. Their use of wings exceed the ones of the typical quadrupedal wyverns perhaps could even rival the flying abilities of wyverns like Rathalos or Rathian. Those wings allow them to hover in air for long periods of time, similar to a Rathalos.
Barioth are skilled evasive monsters. When feeding, these wyverns prefer to eat the soft internal organs of their prey when compared to tougher flesh. During the Breeding Season, male Barioth will show off their impressive tusks to attract mates. Sometimes males will invade the territory of a female in order to mate with them. This behavior though is not without its risks, as females will attack the males if they have already mated or simply aren't impressed. After a female Barioth has mated it will find a nice secluded cave to raise their offspring in. Females are viviparous becoming pregnant and then having 2-3 fur covered young that hide in the caves of the Tundra. Interestingly, each Barioth has a specialized way of fighting.
