The Sailor Cosmos Q Posket figure presents an elegant, celestial guardian ready to defend the universe. She stands with a poised, balanced silhouette, one foot slightly forward, cape billowing as if caught by a cosmic breeze. Her hair flows long and luminous, styled to convey a sense of timeless grace. The sailor fuku is rendered in pristine white with soft lavender accents, gold trim at the collar and brooch, and a shimmering star motif across the chest. Subtle translucent effects on the cape and hair give a sense of weightlessness. The face is gentle yet determined, with large, glassy eyes that reflect a hopeful cosmos.

Sailor Cosmos appears in the Gekijouban Bishoujo Senshi Sailor Moon Cosmos as the future incarnation of Sailor Moon, guardian of the Galaxy and patron of hope across time. She emerges to guide Sailor Moon through a crisis of destiny, revealing the truth about love, sacrifice, and the balance between light and darkness. In the film, Cosmos embodies cosmic wisdom and power, wielding astral energy to protect friends and distant worlds. Her arrival marks a turning point where friendship, self-sacrifice, and the resolve to protect innocence become the keys to overcoming Chaos and restoring harmony.
