Another idea randomly came to mind. It’s a bit of a stretch, but no harm suggesting it anyway. The Frollo brothers from the Hunchback of Notre Dame. Yes, in the original novel, Claude Frollo has a younger brother named Jehan Frollo. I randomly thought of it because I was reminded that this year is the 20th anniversary of the Disney film, and the cast recording for the new stage musical based on it recently came out the other month. Jehan wasn’t in the original Disney film, but he was added to the musical version that I just mentioned. Granted, the film wasn’t a huge success for Disney, and they tend to largely ignore it, so I’m not so sure that they’d be pushing for its inclusion on OUAT. I guess including the Hunchback of Notre Dame wouldn’t be any weirder than the idea of them doing the Lion King, though. Not to mention we did get Cruella, when the idea of adding her to the show felt ridiculous prior to Season 4. Frollo is fondly looked at as one of the strongest Disney villains, with a lot of credit going to the late voice actor Tony Jay.
