and infiltration by seemingly sympathetic Cylons. Escape Four months later the colonials escaped with the help of a resistance movement and the efforts of both the Galactica and Pegasus. The escape required Athena's help. She entered the Cylon facility and took the keys to the various Colonial landing craft. Prior to this a Three found out from a human oracle that Hera was alive and on the planet. She rescued Hera after her adoptive mother was killed during the escape. The Pegasus sacrificed itself to save the crippled Galactica, but the crew survived, joining Galactica. The Cylons then adopted the colonials’ mission to find the home of the Thirteenth Tribe, a planet they called Earth, intending to settle there. They resumed pursuit of the fleet, but upon reaching the Lion's Head Nebula, dispatched a Basestar to investigate. The Basestar took on board a canister left by the Thirteenth Tribe. The canister contained an airborne virus that proved deadly to the Cylons. The virus persisted through the download process, so the Basestar that had been dispatched for the investigation was abandoned to avoid contamination. The colonial fleet discovered the Basestar and captured the ailing Cylons. The colonial fleet's attempt to use the virus to wipe out the Cylons was defeated when Helo, repulsed by the strategy, had the captive Cylons killed while out of range of a resurrection ship. Meanwhile, Boomer turned increasingly anti-human. She was charged with Hera's care, but Hera rejected her. During a truce negotiation, Boomer told Athena that her daughter was alive but sick on the Baseship. She invited Athena to come to the Baseship and rejoin her people, because the occupation showed that humans and Cylons were incompatible and that humans would never truly accept her. Centurions The Cylon Centurion is a mechanical infantry model, made less intelligent than human models. BSGr Centurions retain the silver appearance, robotic body, helmet-like head and oscillating red bar eye of their forbearers but are larger, taller, stronger, more agile and have a more streamlined appearance. They also have retractable guns built into their lower arms, bladed fingertips and heavy armour. The Centurions were monotheists who believed in a single loving God. Initial models The first colonial Centurion is seen and is identified as a "Cybernetic Lifeform Node". Built on contract for the Caprican Defense Ministry, the Cylons are to replace human warriors on the battlefield (Caprica pilot). The U-87
