Kazon to seek an alliance. She escapes Voyager and sides with the Kazon-Nistrim, one of the factions within that species. Chakotay is rendered brain dead, but is made into a disembodied spirit able to possess other crewmembers in "Cathexis". The incident occurs while Tuvok and he were investigating a dark matter nebula, and he sought to prevent the ship from returning there, as an alien species wants to feed on the crew's neural energy. After Voyager enters the nebula, Chakotay possesses Neelix (Ethan Phillips) and guides the ship out using a medicine wheel as a map. Shortly afterwards, The Doctor (Robert Picardo) is able to restore Chakotay's mind into his body. At the end of the first season, Chakotay supported Tuvok's aim of helping the former Maquis crew adapt better to life on Voyager in "Learning Curve", by showing them the enforcement techniques of the Maquis. In the second season episode "Tattoo", Chakotay meets with an alien race who influenced the ancestors of his tribe. They perceived Voyager as a threat because they had thought his people had been wiped out. He was able to resolve the problem using the teachings of his father. The Kazon returned and attacked Voyager in "Maneuvers", where they stole a transporter control module. Chakotay took it upon himself to retrieve the device, recognising that Seska was behind it. He managed to destroy it, but was captured and tortured by the Kazon in the process. He was rescued by Voyager, and shortly afterwards, he was contacted by Seska, who informed him that she had impregnated herself with his DNA. In "Resolutions", Chakotay and Janeway are infected with a virus which requires them to quarantine themselves on a nearby planet. The two began to show signs of affection for each other, but their stay is short-lived after Voyager under the captaincy of Tuvok agrees a deal with the Vidiians for a cure. The pair agree to return to the status quo on Voyager, but remain good friends. Chakotay was contacted by Seska in "Basics" to say that his son had been born, and the Kazon were threatening to condemn her to the life of a slave. Voyager attempted to extract Seska and the child, but it was a trap and resulted in the Kazon boarding the vessel and stranding the Federation/Maquis crew on a nearby planet.
