Mannequin Carmine serves as a subordinate to the antagonist Marsh in the movie *Doki Doki! Pretty Cure: Mana Kekkon!!? Mirai ni Tsunagu Kibō no Dress*. She manifests when Marsh plays his clarinet, emerging as one of three henchmen specifically created to obstruct the Pretty Cure team's escape within memory worlds. Her origin lies in a discarded mannequin that retained a belief in its usefulness, later repurposed by Marsh into a sentient entity.

Physically, she resembles a mannequin with stiff, doll-like skin and proportions. Her appearance includes short dark red or purple hair, a star-shaped tattoo encircling her left eye, and a form-fitting dark red bodysuit, blending artificial and humanoid elements.

Her personality combines cruelty and vanity. She frequently expresses disdain for others, particularly targeting Cure Sword (Makoto), while demonstrating unwavering loyalty and deep respect for Marsh.

Her primary role involves confronting Cure Sword within a Memory World. Utilizing an analytical combat style, she predicts and evades attacks. During this battle, she absorbs surrounding mannequins to drastically augment her size and strength, physically overwhelming Cure Sword by compressing her with enhanced hands. Her specific abilities include significant muscular augmentation, rapid growth in physical stature, and executing the "Mannequin Cutter" attack, marking her as a considerable threat.

Her defeat occurs through the intervention of Cure Ace and Ai, who rescue Cure Sword. Sustaining critical damage from Cure Ace's "Ace Shot" and Cure Sword's "Ultima Sword," she manages to briefly incapacitate both Cures before dissipating permanently. Her narrative concludes within this single cinematic appearance.
