She didn't transform into a full dragon but she only have some features that you can tell she was a dragon. She grew horns, tail, and even wings. All of the features that appeared on her body that is dragonlike are all colored white except for the horns that are both color black. It was a cool transformation. If she is already an adult, she can fully transform into a dragon if she wanted to.
