Blue is the velociraptor at the centre of the Jurassic World films, first introduced in Jurassic World in 2015 as the most responsive member of Owen Grady's raptor pack. Her vocal sounds helped separate her from anonymous dinosaurs, mixing calls, barks and softer rumbles to show recognition and mood. Clips of those sounds later circulated on soundboards and in fan edits, where short raptor calls became easy shorthand for a dinosaur reacting, warning or calming down. This scream and purr pairing remains popular because it captures both sides of the character.
