My favorite Disney Character is the Beast. I love his growth throughout the movie. I like how he gradually fell in love and it became a deeper love that is not built around the physical aspect of a relationship.
My favorite is Ariel. She is beautiful, brave... It's a hard choice, but she leaves her family, her friends and her world, everything she has and everybody she loves for Eric because she loves him so much. She determined to realize her dream, discover another world and stay with Eric. She is fantastic.
I gotta say Hades. Disney is great for creating unredemable villains. Villains that are just plain bad. But Hades takes the cake, manipulative, cruel, hot tempered and greedy. Plus James Woods as Hades made it all the more spectacular.
