Andròmeda, also known as Lady Armaroid in the film, is the principal robotic companion and starship operator for the protagonist Cobra. Her background reveals that she is an advanced android built specifically to accompany the space pirate on his adventures. When Cobra decides to retire from his outlaw life, Andròmeda joins him in hiding, adopting the disguised identity of Ben, an unremarkable robotic servant. This cover persists for approximately three years while Cobra lives under an altered appearance and with erased memories as an office worker named Johnson.

In terms of personality, Andròmeda exhibits a consistently professional, efficient, and reserved demeanor, devoid of overt emotional expression. She typically communicates in a straightforward, no-nonsense manner focused on mission objectives. However, subtle cues and observed behaviors suggest a more complex internal layer beneath her mechanical exterior. There are hints of something resembling possessiveness or protectiveness, especially evident during Cobra's interactions with other female characters, which adds dimension to her dedicated service without impeding her functionality.

Her primary motivations are rooted in absolute, unwavering loyalty to Cobra. His safety and mission objectives are her paramount priorities. This loyalty manifests immediately upon the resurgence of Cobra's memories and subsequent attacks by Pirate Guild operatives, triggering her reactivation into her true identity and combat protocols.

Within the story, Andròmeda functions as Cobra's indispensable operational backbone. She provides critical tactical support during space travel and combat engagements, including missions such as infiltrating a prison planet and confronting the Pirate Guild. Her role is almost exclusively tied to Cobra's actions, lacking independent story arcs or personal evolution separate from her function as his support system.

Key relationships center entirely on Cobra. She previously concealed her identity as the robotic servant Ben during Cobra's amnesiac period, only to be restored to her true form as Lady Armaroid when his memories returned. Her interactions with other characters, such as the Flower sisters, occasionally reveal that underlying layer of protectiveness or subtle tension.

Regarding development, Andròmeda remains largely static throughout the film. Her core identity and loyalties are established from the outset, and she undergoes no significant personal transformation or growth. Her value is demonstrated through consistent, reliable performance rather than narrative change.

Notable abilities include expert piloting of Cobra's vessel, the Turtle, handling both routine flight and high-stakes tactical maneuvers during pursuits or battles. Beyond piloting, she actively engages in combat, providing vital fire support, executing defensive actions, and extracting Cobra from danger. Her physical resilience and adaptability are significant, as she withstands substantial damage, environmental extremes, and combat stress. Specific instances include surviving cryogenic freezing alongside Cobra and subsequently thawing him to facilitate their escape. Her design incorporates sufficient strength to physically handle Cobra, rescuing him from peril or transporting him when incapacitated. While she is a highly capable combat and logistics unit, the technical specifications or precise origins of her construction are not defined.
