Madeline Sycamore/Cure Princess

Cure Princess (キュアプリンセス Kyua Purinsesu) is Madeline's Pretty Cure alter-ego. Her powers change depending on the series, but she is not very strong physically, so she is usually the most "magic"-based cure on the team.

Wedding Form
To transform into her Wedding Form, she must have the Fantasy Tiara in her possession, and transform with the phrase Pretty Cure! Love Wave on! In this form, she can perform the Romantic Waltz attack with Cure Promise. Her dress turns into a formal bridal gown with pink ribbons going around some areas on the dress.

Cure Onyx
Cure Onyx is the result of Cure Princess being brainwashed by the Fantasy Tiara Onyx. She has white hair, and both of her eyes turn to a glowing turquoise color. Her dress is a color inverted version of her regular Pretty Cure outfit. She transforms with the Fantasy Tiara Onyx, and her transformation phrase is Everything's imperfections!
