Ursus (Lain for bear) is a type of berserker or werebear, and has the ability to transform himself into a large bear, though he can control how much of his body is transformed and can transform partially if he wills it. This transformation ability can allow him to seamlessly alter his size, bulk and musculature and transform himself into a burly humanoid, as well as use his transformations to physically augment himself. He has multiple phases of transformation due to his ability to partially transform. His phases can make him physically a hybrid between bear and human, such as giving him the head, paws and bulk of a bear and the shape of a man. He can use his inhuman physicality to fight, especially when he is in full bear form. With this, no normal person can physically overpower him and he is immune to their strength. Desperate, loyal and determined, he is known for his drive to "break the enemy into small pieces".
Like the rest of the team, he was given a special costume to increase his effectiveness and abilities. Part of this costume's equipment is a hand-held mini-gun and its battery pack, both of which are harnessed to his torso for battle, while he carries them both his back when fully transformed. Even while not transformed, he is shown to be strong enough to wield the large weapon and its power source.
