Sarabi (The Lion King)

I honestly think her and Mufasa made one of the best Disney couples, and it's a shame that they didn't have more screen time together. Sarabi is my favorite heroine because she has to deal with the both the loss of her son and her mate, and deals with Scar's taunts and horrible regime with grace and dignity. She never loses her pride, and she is in my opinion one of the strongest Disney characters.
