Samantha, identified as Kikuhime in Japanese, leads The Screws, a bullying trio exploiting robattling abilities to threaten peers. She maintains an aggressive, opportunistic exterior yet conceals unexpected compassion, occasionally aiding friends while refusing to acknowledge this vulnerability. Her opportunism emerges against stronger foes, often prompting alliance offers or retreats over direct confrontation.

Peppercat serves as her constant agile cat-type Medabot partner across media, though she later deploys additional models including Redlace/Redscarleth, Noctocat, Darkpanther, and Sprytooth, adjusting her lineup per narrative needs.

In *Medarot Damashii* (*Medabots Spirits*), Samantha allies with Kilobot creator Kam Kamazaki, accepting upgraded parts for aiding his schemes. These parts prove incompatible with Peppercat, causing robattle malfunctions that fuel her disillusionment with the Kilobot philosophy.

Her character gains emotional depth through a romantic subplot where she develops feelings for Ginkai after observing his embrace of honorable robattle ethics and his partnership with Arcbeetle-Dash. This marks a departure from her earlier persona.

She sustains a recurring rivalry with Erika Amazake, routinely mocking Erika’s strategies. During the World Robattle Cup, she impersonates Space Medafighter X against Team France when the genuine fighter risks arrest after exposure as the Phantom Renegade.

Samantha’s leadership of The Screws remains unwavering, with members addressing her as "Boss" or "Oyabin," reinforcing her authority within the group.
