|Black★Rock Shooter Beast|
|Name in Japanese||ブラック★ロックシュータービースト|
|Romaji Translation||Burakku Rokku Shuutaa Biisuto|
|Weapon/s||Seven Shots, ★rock Cannon, BRSBLADE|
Much like Black★Rock Shooter, B★RSB possesses blue eyes and black hair. However, she now sports a different outfit, along with a shorter hairstyle, and new weapons as well.
Her hands are donned in claw-like gloves similar to that of Black★Gold Saw and thigh-high metallic greaves with blue buzzsaw-like wheels at the base. Her shorts are replaced with a skirt and she now wears a tank-top. Most notably is the blue crown, most likely formed by the flames that emit from her left eye. She also has a necklace above her top in the form of five white stars.
Her weapons of choice is a handgun named Seven-Shots, which is considerably smaller than her traditional, much larger ★rock Cannon, and a much larger sword resembling Dragon Slayer's broadsword named BRSBLADE.
- Like all the known characters, she also has her own emblem in the form of a coat of arms with the crown above the shield engraved with a checkered star and two sword cross each other at the bottom.
- Black★Rock Shooter Beast is the only character to have warning symbols indicating of the destructive power that she has, having a 2 star rating on devastative.
- Unlike BRS, BRSB seems to focus more on close-range combat rather than long-range.
- She seems to be ambidextrous, as in official art and official GSC figma pictures, she holds the BRSBLADE and the Seven-Shots in both hands.
- Although BRSB hasn't appeared in any form of media, a few of her features (her crown and buzzsaw like feet) were most likely used to create Chariot .
