While many characters have a Catch Phrase, it's difficult for a monster, animal, or other kind of non-intelligible creature to have one. As such, they'll often have a recurring noise they make that serves as their calling card: a signature roar. This is not just a roar that a monster happens to make; it is unique to that creature, or in the very least hearing it will instantly remind one of it, thus making it Recognizable By Sound. A Signature Roar is usually a result of a Roar Before Beating. Compare Hell Is That Noise, Signature Sound Effect and Mighty Roar.
Examples:Anime & Manga
- Chopper's Monster Point in One Piece.

- Both Aliens (aka Xenomorphs) and Predators have distinctive roars or screetches that are instantly recognizable.
- Godzilla's iconic and trademarked SKREEEEEEEONNNNNK is heard at least Once per Episode. Other monsters in the franchise have their own distinctive roars.
- The live-action versions of the Hulk has the title character rarely speaking. He does, however, have a distinctive roar since Lou Ferrigno played him in the TV show and voiced him in the movie, the other movie, The Avengers, and the cartoon from the 90's.
- The T. rex's roar in Jurassic Park is impossible to mistake for anything else and has frequently been recycled. Ardent fans of the film series will be able to recognize the sounds of the other dinosaurs just as well; some of the notable ones are Brachiosaurus and Velociraptor.
- The lion in Metro Goldwyn Mayer's Vanity Plate.
- Chewbacca the unintelligible hairy alien from Star Wars has a very recognizable roar.
- The Grey's alpha wolf, alone among the generic howling of the other wolves, has a distinctive snarl so loud and resonant that it qualifies for this.
- Tarzan: Johnny Weissmuller's iconic and trademarked Tarzan yell.
- Tarzan's yell qualifies, as despite being a human, he's known for his famous jungle cry.

- Shadow ships in Babylon 5 have a high-pitched inhuman screech as their signature sound.
- The cat in MTM Productions Vanity Plate is a parody of the MGM lion.

- In Chrono Trigger, Lavos has a very well-recognized Sreeeeeeaaaaach-sounding roar.
- Ganon's skreech in The Legend of Zelda: Ocarina of Time.
- All Pokémon have a distinctive cry; while the anime has them speak their own names, the video games have them making digital noises (often being more advanced and realistic sounding the farther along you go). The earlier games had a tendency to reuse sound clips for multiple species with some modulation, though, with some Pokemon sharing cries as a result (Charizard and Rhydon's are basically the same, for example). As of Pokémon X and Y, almost all of the cries have been redone, making many of them more distinct and/or realistic, as well as giving each Pokemon numerous variations of their cry that are used in Pokemon Amie for the sake of expressing different emotions like joy, anger, and sorrow.
- The Tank's roar in Left 4 Dead is always a signal for disaster.
- Bowser of the Super Mario Bros. games has two different well-known roars from separate eras: the more bestial, hissing roar first heard in Mario Kart 64 and also prominently used in Super Mario Sunshine and Super Smash Bros. Melee, and the deeper, more human-like roar first heard in Super Mario Galaxy and featured in every subsequent game in which Kenny James provides Bowser's voice.
- Most bosses from Terraria use the same roar sound effect when transforming into their second form. Whenever you hear this, you know something bad is about to happen.
- While most bosses use the same roar or no roar at all, the Wall of Flesh has a completely unique roar used for no other boss in the game.
- Mass Effect: the Reapers' distinctive BWOOOOORNGGGGG, which is generally the point when everyone both in and out of universe has to go and change pants. Also, Banshee screams.
- In Final Fantasy VII, the cries of the Planet are pretty distinctive and, while kind of beautiful like whale song, a bit heart-breaking.
Bugenhagen: "Didn't you hear it? As if to say... I hurt, I suffer..."
- Almost every monster in Monster Hunter has a distinctive roar and other vocalizations, to the point where it'd be easier to list the monsters who do not have unique sounds.
- Many animals have a distinctive roar that is impossible to mistake for anything else, such as lions, elephants, bears, and so on. It would probably be easier to list animals that don't have a unique roar.
