Silver Clock serves as one of Marsh’s servants in the film *Doki Doki! Pretty Cure: Mana Kekkon!!? Mirai ni Tsunagu Kibō no Dress*, summoned by the power of a clarinet alongside Purple Buggy and Mannequin Carmine. His form resembles a grandfather clock, equipped with gray springlike limbs, yellow gloves and boots, and a clock-face head featuring a red eye on the right and a gear-like eye on the left. Gray and black-striped horns extend from both sides of his head.

Sent into an altered memory world to confront Cure Diamond and Cure Rosetta, Silver Clock wields his clock hands as weapons and moves with agility thanks to his flexible limbs, demanding respect from his opponents in battle. He eventually merges with Purple Buggy to create a stronger combined entity. This fused form is destroyed by Cure Diamond and Cure Rosetta’s joint attack, the Diamond Blizzard and Rosetta Reflection Double Crush.

Silver Clock has no confirmed appearances or developments in other seasons, movies, OVAs, or spin-offs beyond this film.
