Scorp antagonizes as a member of Eternal, presenting as a brown-skinned adult male with short red hair and bright red eyes. He favors a navy suit layered with brown leather straps, a red scarf, fingerless gloves, and blue boots featuring similar straps. Combat triggers his transformation into a monstrous scorpion-like humanoid: purple skin with red-orange accents, teal gem-like joints, yellow-orange chest hooks, and a prominent helmet-mounted tail. A green visor conceals his eyes, which visibly enlarge when angered; removing this visor activates heightened combat capabilities.

He shares prior history with Syrup from their time together in Eternal. Initially operating solo, Scorp relentlessly pursues treasures like the Rose Pact and Cure Rose Garden, clashing with the Pretty Cure by conjuring Hoshina monsters from everyday objects—bookshelves, asphalt, fire hydrants. Repeated failures strain his standing within Eternal, drawing Anacondy's ire.

His dynamic with fellow agent Bunbee evolves significantly. Scorp initially scorns Bunbee’s persistent name mispronunciations—"Scorn," "Stamp," "Slipper"—and dismisses warnings about the Pretty Cure. Tensions ease when Bunbee offers cakes during a stressful moment, revealing unexpected kindness. This sparks collaboration: Scorp discloses Eternal’s secret of imprisoning failures in an underground maze and co-proposes kidnapping Coco and Natts. Their partnership solidifies into genuine friendship.

In his final battle, Scorp removes his visor during an assault on the protagonists’ base, accessing enhanced power. Overpowered and struck by "Milky Rose Blizzard," he reverts to human form. Vanishing, he whispers "Farewell... Bunbee," acknowledging their bond. His story concludes without further appearances.
