Finn was one of the Betafarl technicians who accompanied Zukan to Xenon Base. He alone was aware that Zukan was working with the Federation. He noted Zeeona's presence on the base and told Zukan, also planting explosives to seal off all the base's exits prior to the release of the radioactive virus Zukan had planted.
Finn left the planet with Zukan and together they met with Servalan. As they waited for news, Finn noticed a bomb that Servalan had planted in the airlock. Zukan sent him to remove it from the wall, then opened the airlock and flushed him out into space. (D: Warlord)
