In Super Mario, an ex-Princess turned Thief

Dyamatt is the former Princess of Prism Island, dressed in a steampunk-gothic style. She is rather short in stature, has black hair in a ponytail, and blue eyes.

She is frank, direct, unfiltered, mischievous, confident, independent, audacious, impertinent, avid, addicted to adrenaline, charismatic, venal, and greedy.
