Being an Anodite, Sunny is a free spirit that cannot be caged. However, it turned her into a spoiled brat.

Sunny has little to no regard to what is around her and will often attack anything just for the sake of fun and has limited self-control. Additionally, she seems to hate it when people do fun things without her. She also hates people who tattle to her parents. 

Sunny has respect (and slight fear) of her grandmother Verdona.
