==Biography==
Zen was the ship's computer of the Liberator. It activated after Jenna Stannis randomly operated a control, immediately identifying her and the other new crewmembers, Roj Blake and Kerr Avon, by name and also named the ship based on a thought of Jenna's. Zen showed a willingness to obey the new crew, taking them to required destinations and warning them of dangers, but also failed to provide information on occasion, leading Olag Gan to suggest it had been programmed with a limiter to stop it helping them. It refused to bring the capsule containing the Programmed Guardians on board but failed to explain why, leaving Blake and Jenna stranded aboard with limited air. It also refused to take the quickest route to Space Station XK7 since it meant travelling through a dangerous area, and shut down when the crew entered the area anyway.
Zen was capable of being controlled both by Orac and by the System, the ship's original creators. As a result of this, Blake instructed Orac to programme Zen to only respond to recognised crew. When the Liberator was damaged after the Intergalactic War, this prevented the Federation taking control of it, since Zen continued to obey instructions from the previous crew and retrieve them. Avon had it programmed to obey instructions from new crew Del Tarrant and Dayna Mellanby. When the Federation boarded the ship again, Zen was programmed to obey the orders of Servalan, but Avon had the voice print erased when the former crew regained control.
On the Liberator's last voyage to Terminal, Zen advised Avon against taking the ship through a particle cloud but underestimated the danger, as fluid particles began eating away at the ship. Having failed to find a solution, Zen devoted its remaining power to maintaining the teleport so the crew could evacuate. Its last words as it shut down were "I have failed you. I am sorry. I have...", which Vila Restal noted was the only time it had referred to itself as "I".
