Ursa

Ursa are large, dark, bear-like creatures of Grimm.

The Emerald Forest
While Yang Xiao Long is looking for someone in the Emerald Forest, she hears something in the bushes and wonders if it is her sister, Ruby Rose. However, two Ursa appear from behind it and attack. Yang fights them off almost playfully until one cuts off a small strand of her hair. Yang goes berserk and punches one of the Ursa multiple times, launching it through a group of trees. She turns to confront the other one, but Blake Belladonna manages to kill it with a single strike. After being killed, the Ursa starts to smoke, possibly meaning that they dissolve after being killed.

Players and Pieces
An Ursa is seen rampaging through the forest, while Nora is riding it, until it is in visible sight to Blake and Yang. However, the Ursa is quickly killed by Nora, who quickly states that it's broken.

Appearance
They appear much like the new Beowolves, with black fur and bone spikes on their backs and arms, as well as a white mask with red detailing, but are much larger and stockier.

Abilities & Powers
They are first shown in Episode 6 attacking Yang, though they don't manage to land a strike on her. It seems that they are slower, but possibly stronger than Beowolves, being able to shrug off several blasts from Ember Celica. They seem to prefer attacking in pairs, suggesting pack ties or familial ones when hunting prey.

Trivia

 * The fact that Yang fights these bear-like creatures in the woods could be an allusion to the fact she is based on Goldilocks, who similarly encountered a number of bears in the forest.
