Young Ursula
Why would it be Tiana when we have like a million new villains?
I’m skeptical it’s a Young Ursula for one reason. How many times do they announce a casting call for a younger version of a pre-existing character with a pseudonym? Normally they outright say their correct name if it’s just a younger version of a pre-existing character, or they don’t announce the casting call at all. So I’m going with Tiana. As Corbin mentioned, they didn’t mind shoehorning in Rapunzel as a one off, so who’s to say Tiana wouldn’t be? I won’t rule out Ursula, but I have my doubts.
