Let’s just get this out of the way, Clopin says malediction instead of Frollo, can no version ever get it right? I kid.
Clopin in this version, like in other versions, is the leader of the Court of Miracles and the leader of the outcasts, in this case the Cubans. He doesn’t do all that much but he is a big catalyst for the story. He is one who “curses” Quasimodo and made him ugly AND he is the one who arranges the swap of Esmeralda and Quasimodo for their terrible parents. Otherwise he doesn’t do that much. He wanted to attack the cathedral to save Esmeralda but thought better of it because Quasimodo was both very strong and was acting a lot of impulse but throwing stuff of the cathedral fairly unprovoked.
That being said, Clopin is shown to be smarter than all the characters and saner, though that doesn’t take much in this movie. All in all, he is likable, I just wish he got to do more.
