Dr. Peach

Dr. Peach is the doctor persona that Princess Peach takes in Dr. Mario World and one of the playable characters. Like the other characters, she has a unique special ability: when activated, a pink beam of light appears and clears a random column on the board. Her outfit highly resembles the outfit her regular self wears at some kingdoms such as the Metro Kingdom in Super Mario Odyssey. Notably, Peach had previously been depicted as an assistant to Dr. Mario as "Nurse Toadstool," although this was confined to supplementary materials, aside from a woman resembling her in prototype builds of the original Dr. Mario.
