- Family: Agnaktor
Glacial Agnaktor are found only in the Tundra.
Glacial Agnaktor preys on Bullfango, Anteka and Popo. The Leviathans may also prey on Baggi, Great Baggi, and Lagombi as they have few defenses other than to flee when confronted with the powerful predator. Like their Volcanic dwelling relatives, the Glacial Agnaktor are top predators in their environment, yet like their relatives, they compete with other large predators such as Barioth, Tigrex, Brachydios, Deviljho, Stygian Zinogre, and Gigginox along with its subspecies Baleful Gigginox. When making a kill they sometimes leave it to rot and then return to feed on the much softer flesh. These creatures will sometimes even leave a carcass as a trap in order to ambush smaller predators from below.
Glacial Agnaktor is capable of traveling through solid ice and permafrost of the Tundra. Their beak-like jaws are substantially sharper and more spear-like than their relatives in the Volcano which allows them to pierce through the solid ice with ease. Glacial Agnaktor coat themselves with layers of ice. With Dewy Pleura on them, Glacial Agnaktor are able to coat themselves in this ice armor. This ice armor gives these creatures an excellent form of body armor that can protect them from attacks of predatory species. The claws of this species are used as spikes to prevent slipping on the ice. This species is also capable of shooting a large powerful blast of frigid water.
Like Agnaktor, Glacial Agnaktor are highly aggressive.
