phoebus, hunchback of notre dame.
Well, yes, I agree! (He actually came to mind before I even remembered John Smith.) But he’s not “officially” a prince :/ Actually though, I was thinking about this in general. If they were to actually include the other heroes and heroines instead of making it “princess” exclusive, we’d have a greater variety. Jane and Megara immediately come to mind as two more brunettes to add. Phoebus would be the added blonde to the Disney male line-up and Herc a redhead. Esmeralda and Tarzan can join the majority that already exists with black haired princesses and brown haired princes.
