Towering over 20 feet tall, the Jotunaq are incredibly powerful; they are able to take down a single, mature Ice Giant in one-on-one combat, and more challenging opponents with the element of surprise. Covered in shaggy white fur, their black hide is hidden and blends the behemoth among the ice and snow. Their skin color helps absorb heat and its blubber insulates their body, preventing Jotunaq from freezing. A muscular body, the animals are bulkiest around the shoulder; long distance treks, strong swipes, and high carrying capacities are possible due to these specific muscles. One might think that their claws and teeth are primary weapons - but this is not so. While teeth and claw can cause great harm, teeth are mainly utilized for tearing meat from carcasses and claw for traversing ice. The Jotunaq's tusks are their main combative feature.

A fearsome, well-adapted predator, Jotunaqs have one significant disadvantage: their eyes. Unable to see far or underwater, those that use this weakness against them have the upper hand. Sharks are the primary predator of Jotunaqs; slow, inefficiant swimmers, their poor sight provides the perfect opportunity for animals like Megalodons.
