Rajang is a Fanged Beast from Capcom's Monster Hunter series, first appearing in Monster Hunter 2 and returning in Monster Hunter World: Iceborne, where this roar is taken from. Known for its ape-like build, horns and extreme aggression, Rajang becomes especially feared when enraged, with its fur turning golden and its attacks speeding up. Clips of its scream spread through gaming communities and soundboards because the performance is instantly recognisable, even without gameplay footage, and it now works as shorthand for a boss-level threat or an over-the-top rage moment.
