Le Master of Disguise is a witty trickster who is played by Pablo. He was formerly trying to run away from Inspecteur Austin of the Paris Police. He owns many disguises (hence the name) and is almost never seen without one on.
Le Master of Disguise is mostly blue. When he is not in disguise, he only wears a brown fedora; the fedora is nearly identical to the one that Desert Quester Pablo wore, with the exception of a tan band, as opposed to a black one.
He has a myriad of outfits based on roles from previous episodes. His conductor outfit consists of a blue hat, a dark blue suit, a white dress shirt, a teal tie, and dark blue pants. His waiter outfit consists of a white coat, a white dress shirt, a black tie, gray-and-black striped pants, and black shoes. Impersonating as Inspecteur Austin, his disguise consists of a deep purple suit, a black-rimmed purple fedora, and a novelty mustache.
Pablo has played Le Master of Disguise in one episode of The Backyardigans: "Le Master of Disguise" from season three.
