The clip is tied to Brooklyn Nine-Nine, the sitcom known by fans as B99, and to Captain Holt, its famously straight-faced precinct captain. That pairing is why the short line travels so well online: Holt's serious, no-nonsense persona makes a beast-mode slogan feel both sincere and absurd at once. Shared as a meme sound, it is dropped into sports edits, gym clips and comeback montages whenever a creator wants a calm, authoritative push before the action, keeping it useful long after the show's original run.
About this sound
Captain Holt's Unleash the Beast line from Brooklyn Nine-Nine, a short clip creators use to hype a comeback, a workout set, or a reveal in memes and edits.
This three-second clip captures Captain Holt delivering the phrase 'Unleash the Beast' in his famously deadpan, authoritative tone, turning a motivational slogan into something unexpectedly funny because it comes from Brooklyn Nine-Nine's most serious character. The delivery is clipped, controlled and confident, with no shouting or music behind it, which makes the line land like a quiet command rather than a hype speech. In an edit, that contrast does the work: the viewer expects a roar and gets Holt's calm intensity instead, instantly signalling that something impressive, chaotic or over-the-top is about to happen.
