Tiara is a character introduced in the game Super Mario Odyssey. She is forced into helping Bowser and becomes Princess Peach's wedding tiara, which was the reason she was wearing a tiara instead of her usual crown. She is also the younger sister of Cappy, Mario's new ally.

After rescuing Princess Peach and Tiara, they appear in different areas in every kingdom, which they reward them a Power Moon.


Tiara's default form is a beautiful large white and silver tiara with magenta eyes. Under the hat, she has a small spectral body similar to a Boo. Tiara can take the form of different hats, including Peach's Tiara. Her large eyes appear in all of her appearances.
