The Beast - Beauty and the Beast
I don’t think this a very “traditional” transformation, it’s not the actual physical tranformation from beast to man that I like, it’s the mental and emotional changes he has. Even when he was originally a man he was selfish and self-centred. Belle teaches him to love and show kindness and become the best he could be.

Ursula - The Little Mermaid
This was a hard choice because I also love Maleficent transformation. This one has come out on top because I love the words Ursula says during her transformation(i’ll see him wriggle like a worm on a hook) and her laugh which makes the scene complete.
