These are so hard to pick, especially the "Other" category!
Princess for me would have to be Belle, because I identify with her most. Strong, intelligent, independent, but misunderstood by so many around her.
Fairy is hard in the sense that none of the fairy characters have ever really been favourites of mine. (Don't hurt me!

) Tinkerbell would be number one based on association with Peter Pan.
For other, I'll have to go with Mickey, because he's the classic and a big reason why we have Disney in our lives.
