Like her eighth cousin, Luan, Cornelia has a fondness for comedy and making puns. However, unlike her said distant relative, her jokes are much more funnier and very hilarious, getting the laugh out of everyone she makes jokes with, even her more serious father and brother.
Cornelia has light brown hair worn into a ponytail with a green scrunchie. She wears a white sleeveless shirt, a green shirt, brown shoes, and green striped socks. She has three flowers: she has a pink flower on her shirt and a gold yellow flower on each of her shoes. She also wears a wooden crucifix which she wore during her Confirmation.
