Breaking Dawn explores the positive and negative consequences of the characters' transformations from human life to supernatural life. While Leah is strong and her speed is unmatched as a werewolf, she can't bear children. Bella, on the other hand, quickly overcomes the negative consequences of being a newborn vampire because she chose her transformation and had thought about it for a long time. Yet, she struggles with the fact that she poses a danger to her daughter, her human father, and humankind.
