A cousin to the lycans, ursathropes, or ursa (plural) are very similar to their more canine relatives. Instead of morphing into wolf-like creatures, they can morph into bear-like creatures. These forms can vary in size from a common black bear to a monster the size of a bull elephant. Although they share the same weaknesses as lycans, such as decapitation and silver poisoning, they can take a lot more damage before dying than lycans. They also are much stronger than lycans, capable of killing even supernaturals with a single swipe of their massive and deadly claws. Although they can see better than normal humans, their eyesight is nowhere near the strength of other supernatural. Their smelling and hearing capabilities are about equal to a lycans, though. Another weakness is that their human bodies are equal in strength to a humans, with all their powers focused on their ursine form. Due to this, ursa rarely leave bear form, which causes some mistake them for bears that can turn into humans.

Ursa tend to match the personalities of bears quiet well, sharing many traits. For example, all ursa must hibernate during the winter months, and will spend much of the year preparing for this. Hibernation is one of the key reasons that ursa tend not to target humans as food. They prefer going for more fatty food morsels, and will only target humans if they are a threat or trespassing. This leads up to the territorial side of the ursa. They are extremely solitary and territorial, and will kill another ursa if thrown in the same room together. The only time they will come together peacefully is when they intend to breed, which is an extremely rare event. Most ursa form when one ursa attacks a human and lets them live, who they in turn become ursa themselves. Because of their solitary nature, a newly turned human will become a full ursa on their own, because if they required the original, they would kill each other on the spot.

When the humans began hunting supernatural, one of the first species to dissapear were the ursathropes. Their large size and terrifying appearance made them prime targets, and their numbers decreased to critical levels. Due to the extremely low rate at which ursa form, their numbers never recovered, and now seeing one has become a rare experience. Populations of them still exist in the Russian and North American taiga forests, although they rarely go near human settlements anymore.
