Clopin is the leader of the gypsies, and is exceedingly protective of their headquarters, the Court of Miracles. Clopin is unusual for a prominent Disney character because of his neutrality towards both good and evil. One moment he is performing street theatre for children, then he dances throughout town as the Feast of Fools celebration is underway, and the next, he's about to hang the movie's heroes. He maintains a rather macbre sense of humour even when arranging the hanging of Quasimodo and Phoebus.
He uses puppets and street theatre to tell stories, sometimes using one of himself which he will argue with in jest, and ultimately always overrules.
As the movie's narrator, Clopin has a great deal of knowledge about Quasimodo's past, seemingly more than Quasimodo himself, suggesting that to know the whole story, throughout Paris he must have a great deal of contacts.
Clopin appears at the beginning of the movie, narrating to Parisian children through street theatre and the song "The Bells of Notre Dame" the story of Quasimodo, explaining how Frollo all but murdered Quasimodo's mother, and then intended to drown her child before the eyes of the Virgin Mother, Notre Dame herself. He explains how the ArchDeacon stops Frollo from killing Quasimodo, and the cruel meaning of his name.
Clopin is next seen singing the song "Topsy Turvy", leading the Feast of Fools and dragging Quasimodo into the song despite his attempts to hide. When Quasimodo is pulled up on stage and it is revealed that he is not wearing a mask but it is his true face, Clopin hurries to calm the shocked crowd, pointing out that "We asked for the ugliest face in Paris, and here he is, Quasimodo, the Hunchback of Notre Dame!" He then leads the crowd in crowning Quasimodo. He plays no part whatsoever in Quasimodo's humiliation.
Clopin next appears in far less gaudy attire to sing "The Court of Miracles" when Phoebus and Quasimodo discover the Court of Miracles, arranging for the rapid hanging of them both as he suspects them to both be spies for Frollo. Esmerelda stops him from opening the trap, and he claims ignorance of their innocence (albeit in a manner that suggests he simply wasn't listening). Unfortunately when Quasimodo is tracked to the Court, Clopin is shown captured as well as the other gypsies, Esmerelda, and Phoebus.
His fourth appearance is briefly during the climax of the film where Esmeralda is at the pyre before Notre Dame. When Quasimodo rescues Esmeralda, Phoebus breaks free and rouses the civilians into action, and Clopin is seen jumping out of one of the many cages that hold the Gypsies freed by the civilians. Along with the civilians they attack Frollo's soldiers.
Finally, Clopin lifts one of the small children seen at the beginning as Quasimodo leaves the cathedral, and sings the reprise of "The Bells of Notre Dame" as Quasimodo is led as a hero through the streets of Paris.
In The Hunchback of Note Dame II, Clopin is no longer the narrator as in the first one and plays a much smaller role. He's seen at the beginning of the movie singing about the Festival of Love with Quasimodo and the rest of the civilians. Then he's later seen again playing with his puppets in front of a crowd that is based on the Festival of Love. Then, just as in the first one, he's seen introducing Esmeralda as she dances for the festival.
Role in the series
He will appear in the Spongebob series in his debut movie. But at first, in the Wonderland fiasco with the Wonderlandians infected with Clopin's madness. And then in the upcoming Ed, Edd, and Eddy movie with Mandy and Bloo (and other cartoon network characters, the ones before todays programing) reteating the simuler song.
