Ursai[1][2] are large, bear-like Creatures of Grimm that first appeared in "The Emerald Forest" in Volume 1. They have appeared in two varieties: the smaller, more common Ursa Minor,[3] and the larger, better armored and more powerful Ursa Major.[3][4]


They appear much like the Beowolf, with black fur and bony spikes on their backs and arms, as well as white, bone-like masks with red detailing, but are much larger and stockier.

There are also larger Ursai in the world, known as Ursa Majors, and one was seen living in the Forever Fall forest. Like its smaller counterpart, it has bony spines and a skull mask with Grimm markings, but also possesses many bony plates on its back and limbs.

In the "Volume 5 Yang Character Short", the Ursa underwent a visual change, with a more angular head, prominent ears, and longer spikes at the ends of their mask. Like the new designs of the Volume 4 Beowolf, black smoke also seems to emanate from their bodies.

In "Out in the Open" a Solitas version of the Ursa Major known as the Ice Ursa is seen during the attack on Mantle. Most likely due to the fact that they inhabit the cold tundras of Solitas, the black fur of the northern variant of the Ursa Major appears to be somewhat frozen and has white patches. Additionally, the spikes along their backs have seemingly completely frozen over, now having an icy blue color to them.

RWBY: The Official Manga

Ursai have a very different appearance in this manga than they do in the show. The Ursai are slight larger and lack the large spikes on their backs. They also have a half bone-like mask and feline ears.



In "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 Ursai appear out of the bushes and attack. Yang fights them off almost playfully until one cuts off a tiny strand of her hair.

Yang goes berserk and punches one of the Ursai 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 from Gambol Shroud.

In "Players and Pieces", an Ursa rampages through the forest until it is in sight of Blake and Yang. The Ursa then collapses due to it being shot in the back, revealing that Nora Valkyrie had been riding it. She is left apparently saddened that it is "broken" and looks over the body to see if it was still alive.

Jaune defending Cardin from an Ursa Major

An Ursa Major comes out of the woods and attacks Team CRDL and Jaune Arc in "Forever Fall, Pt.2". It appears to focus on Cardin Winchester due to the red sap on his body, similarly to how bears have been observed to show a strong enough appetite for honey to risk bee-stings to taste it, despite Grimm being commonly believed to not require sustenance. Despite the fact that Cardin bullied him, Jaune was willing to help his classmate by defending him.

After a short battle, with Pyrrha Nikos using her Semblance to assist him, Jaune killed the Ursa Major by decapitating it.

An Ursa can be seen behind a Creep in the tunnels leading to Vale in "No Brakes". Later, the Ursai, including some Ursa Majors, enter the city when train breaks the barrier to Mountain Glenn in "Breach". Once again, Jaune fought an Ursa, but unlike with the Ursa Major, he managed to take it down on his own after a series of blows. Meanwhile, an Ursa Major was killed by Emerald Sustrai with Thief's Respite. Another was destroyed by Fox Alistair.

In "Beginning of the End", Ursai are among the Grimm that head towards the city of Vale, drawn by the negative emotions there and are dropped into the city itself by the White Fang.

In "Battle of Beacon", an Ursa could be seen getting knocked down by Jaune's shield charge.

In "Volume 5 Yang Character Short", Yang fought an Ursa on Patch after thinking Ruby was in danger.

In "Out in the Open" Ice Ursa are among the Grimm attacking Mantle and are fought by Blake. Later in "Midnight" a statue of an Ursa was seen inside the Glass Unicorn restaurant. During the Battle of Atlas, Ursai were among the Grimm created by Salem to fight against the Atlas Military.

RWBY: Grimm Eclipse

In Grimm Eclipse, Ursai are among the creatures of Grimm encountered by Team RWBY in Forever Fall and Mountain Glenn.

RWBY: After the Fall

In After the Fall, Team CFVY is confronted by eight Ursais in their initiation.

Later, an Ursa kills Linus Gray as he tries to escape the destruction of Lower Cairn with Team CFVY.

Powers and Abilities

They are first shown in "The Emerald Forest" attacking Yang, though they do not 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 ties of pack or familial origins when hunting prey.

However, the Ursa Major that appeared in "Forever Fall, Pt.2" was far larger and stronger, effortlessly overpowering Cardin and managing to endure a direct slash to its unarmored belly from Jaune's sword. It was only defeated when Jaune decapitated it.

In Grimm Eclipse they can slam the earth beneath them to cause a line of rocks to protrude out of the ground as a long-ranged attack.


  • Their name comes from the Latin word for bear.
    • Although ursae is the Latin plural for the word ursa, the plural is given as "Ursai" according to in-episode captions[1] and published scripts.[2] The word probably does not follow the standard plurals because Latin doesn't exist in Remnant.
  • 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 also encountered bears.
  • The name "Ursa Major" is likely a reference to the constellations of Ursa Major and Ursa Minor.
  • Russel Thrush's lines referencing Ursai from "Forever Fall, Pt.2" were remixed into a techno song and music video, "That's a Big Ursa!", that is featured as an easter egg on the Volume 1 DVD. In the video, two Ursai can be seen dancing alongside Russel at Junior's Club. This remix is utilized as Jaune Arc's ringtone in "Breach".
  • An Ursa was featured as one of the monsters in the Five Nights at Freddy's episode of Immersion, another series from Rooster Teeth. The Ursa resembles Freddy Fazbear, the titular main antagonist.
  • Nora recounts a dream where she makes money by selling Ursa-skin rugs; however, the Ursa, and its skin, would have evaporated upon death, as all Grimm do.
