Movie
Description
Cook is a diminutive, doll-like entity possessing light green eyes with distinctive purple star-shaped pupils. Her pale green hair forms tight curls, styled with thick bangs and long forelocks. She wears a white dress adorned with scalloped wrist cuffs, a red bow-tie, and a light blue apron. A chef's hat rests on her head, pierced by two sickle-like antennae. Despite her doll-like form, she is explicitly a monster.

Outwardly friendly, Cook masks a cunning, scheming, and deeply vengeful nature. This bitterness originates from her past life as a pastry chef whose creations faced constant rejection, leading to a failed business and profound resentment. Her bitterness only intensified after death, transforming her into a monster. Jean-Pierre Zylberstein discovered her dwelling within an ancient recipe and appointed her as his assistant, unwittingly enabling her vengeful designs.

Cook harbors intense jealousy toward Kirahoshi Ciel, a prodigious patissier who achieved the recognition she was denied. This jealousy fuels her repeated targeting of Ciel throughout the film. Serving as Jean-Pierre's assistant, she manipulates his obsession with crafting the "Ultimate Sweet," gradually driving him toward madness. She orchestrates attacks on Paris by animating pastry monsters and curses the Kirakira Pretty Cure team. Her curse reverts Cure Parfait (Ciel's transformed state) to her fairy form and transforms the other Cures into animals antithetical to their themes, hindering their efforts.

Her schemes escalate when she pushes Jean-Pierre into the batter of the Ultimate Sweet, merging him with the creation to unleash havoc. She confronts the Cures directly, expressing fury when Ciel overcomes her curse. In a final bid for success, Cook merges herself with the Ultimate Sweet after Jean-Pierre is rescued. This fusion is ultimately purified by the Cures using the "Animal Go Round" attack. During purification, Cook recalls Jean-Pierre's past kindness—he was the sole individual who ever appreciated her efforts—before dissipating into sparkles.

Following her defeat, Cook reincarnates as a young girl resembling her original form. She appears outside Jean-Pierre's renovated workshop, eager to learn. Although he doesn't recognize her, he accepts her as his new apprentice.

Cook frequently ends her sentences with the verbal tic "~cook!" (~クク!).
