Red is a demonic feline in appearance with red fur (hence his name), yellow eyes, brown claw-like fingernails, and wears a blue robe. In his dog disguise, he looks like a St. Bernard and wears a red robe, scarf, fex and a pair of slippers. As a monster, he is gigantic, muscular and has glowing red eyes.
Red is a power hungry psychopath. Proud and cunning, he prides pure evil and being evil, and doesn't approve of any "entry level wickedness". In addition to being a hellish feline, he also has the many characteristics of a cat, he eats rodents, he hates water (proven near the end of the film during the battle between him and Charlie), and he thinks very low of dogs (especially his sidekick Carface), and desires full domination over all dogs on earth and heaven, which plays a keen role in his goal to obtain the horn. He is very persuasive and deceiving, with the exception of disguising himself as an elderly dog to manipulate his victims, and also very hotheaded, as he tends to lash out whenever his patients are tried, such as when he snapped at Carface after his minion expressed enthusiasm over wanting to make money with the horn's power, still oblivious to what the horn would really be used for. But power seems to excite Red as well, proven when Red gets Gabriel's horn. He takes no notice of anything going on around him and when Carface says that Charlie and his friends are getting away Red merely says "Let them".
All Dogs Go To Heaven 2
He is a powerful cat demon who recruited Carface in his plan to use the magical Horn of Gabriel to literally pull all the dogs (and quite possibly every other animal species if he got the chance) from Heaven and imprison them in Alcatraz prison and transport them into Hell, thereby damning every single species in the world.
To this end, he tricked Carface's old nemesis Charlie into aiding him via creating magical-collars and forcing him into a deal. This climaxed in the demon managing to actually get the horn and he began to imprison the inhabitants of Heaven (including Annabelle) and growing into a monster of seemingly apocalyptic proportions, causing the sea itself to start to rise around the island in a massive whirlpool. However, Charlie and his friends decide to fight back, resulting in a battle that ended with Charlie blowing the horn, reversing the evil spell. Red, who had already been weakened by the battle, was ultimately dragged back to Hell to face punishment for his failure.
