Predominantly identified as Lady Armaroid, this character—alternately referenced as Andròmeda in one English adaptation—functions as Cobra's principal robotic companion and starship operator. She provides critical assistance during space travel and combat engagements, delivering tactical support in missions such as infiltrating a prison planet and confronting the Pirate Guild. Her protective capabilities include rescuing Cobra from scenarios like cryogenic imprisonment and enemy assaults.

Lady Armaroid exhibits a consistently professional and reserved demeanor, devoid of overt emotional expression. She previously concealed her identity as the robotic servant "Ben" during Cobra’s amnesiac period. Her operational capacities encompass piloting, combat assistance, and logistical support, though technical specifications or origins remain undefined. The alternate name "Andromeda" reflects no additional traits or background. Her involvement is exclusively tied to Cobra’s actions, lacking independent story arcs or personal evolution.
