Ensign Peanut Hamper was an exocomp who served in the Federation Starfleet aboard the USS Cerritos in 2380. Her paint job was designed to resemble a Starfleet uniform with the appropriate rank insignia and division coloring.
Eschewing an alpha-numeric name because she "didn't want to sound robotic", Peanut Hamper chose her name on the basis of an algorithm to determine a "mathematically perfect name" after a study of all Federation languages.
She was initially excited to serve aboard the Cerritos. She was assigned a liaison officer in the person of Ensign D'Vana Tendi. Ensigns Peanut Hamper and Tendi served in the ship's medical division. Peanut Hamper initially struggled with tool manipulation, but displayed a strong aptitude for sensitive surgical procedures that impressed Dr. T'Ana.
In spite of this initial success as a new member of the crew, Ensign Peanut Hamper became fearful and selfish when she was asked to undertake a dangerous mission to deploy a computer virus into the systems of a hostile Pakled Clumpship. Peanut Hamper refused to undertake the mission, declared that she had only joined Starfleet to anger her father, and deserted her ship and crew by beaming herself off the Cerritos. She was subsequently stranded in deep space. (LD: "No Small Parts")
