Red is a supporting character in Cars, Cars 2 and Cars 3.
Appearance
Red is a fire truck with a red paint job like Lightning McQueen and Mack hence the color as a name option for the character in the film. He has shiny silvery detail all over him including his fire hose. He also has black water pipes stored on both sides where the water pressure gauges meet. The ladder rests in the back as another unique detail toward the character's craftsmanship.
Personality
Red is a very shy, emotional and friendly character who lives in a firehouse in Radiator Springs, where the statue of Lizzie's late husband Stanley (the town's patriarch) appears. During recording sessions, the late Joe Ranft managed to manipulate Red's emotional sound effects in the same order as Heimlich the caterpillar from A Bug's Life. The difference between Heimlich's whimpers and Red's cries were the pitch levels of sound effects that were processed in editing after Joe Ranft's recording session. Heimlich's whimpers were high-pitched in the performance scene of A Bug's Life, whereas Red's cries were low-pitched and deeper in the sound mix before the film was made. Red cries and drives away because he was still upset at the destruction of the flowers that he must water with his firehose. One of the things that Lightning McQueen did was destroy Red's flower garden. Red began gasping and ducking at the same time when that happened. At this point, he stayed inside the garage of the firehouse when McQueen was at the scene of destroying a lot of property in Radiator Springs. During the film's resolution, Red forgives McQueen by warming up to him, even though he did burst into tears and drove away at the same time. He did that because he thought McQueen left without saying goodbye.
