For the 1989 Disney film of The Little Mermaid, which I think is mostly a complete story (you have to give it a break for its short running time), Ariel’s father King Triton is definitely the IC, with maybe a period where Sebastien the crab (as the King’s agent) takes on that role. And Ariel is Steadfast while King Triton Changes. (But I’ve heard the Hans Christian Andersen fairy tale is quite different so it certainly makes sense it could have a different IC.)
