This is a Subspecies to Agnaktor that appears in Monster Hunter Portable 3rd. It attacks with a Ice beam similar to the normal Agnaktor's fire beam that inflicts Snowman, Iceblight, and Waterblight. Unlike the normal Agnaktor, it can sweep the beam from side to side as well as moving it in a circles. Also it will be able to dig up into the ceiling in Areas 4, and maybe 5. It's covered in snow, which will most likely turn to ice when it hardens. When low on stamina it won't be able to fire its ice beam, like the normal Agnaktor. It also possesses several attacks that take advantage of its slippery environment, such as a belly-slide and a sliding, double hipcheck. It also appears that it has a sharper and longer beak for digging through the hard tundra earth than its lava-dwelling relative. This Subspecies is also known as the Frozen Halberd Wyvern.
