Zho'Kaan fired on Tucker's shuttlepod while it was on a test mission, causing it to crash on the moon. Zho'Kaan's ship was also damaged and landed on the moon as well. Tucker attempted to repair his transceiver in order to contact Enterprise, but was attacked by Zho'Kaan, who stole the transceiver in order to contact his own ship. Zho'Kaan captured Tucker and demanded that he fix the transceiver. Tucker escaped and managed to capture Zho'Kaan. After this battle, Zho'Kaan and Tucker realized that to survive the hostile environment, they must work together. Zho'Kaan healed Tucker's wounds by spraying him with a strange fluid from his mouth. Together, they took the transceiver to higher ground to contact their ships.
During the trip, Zho'Kaan became dehydrated; the resulting cellular breakdown made him unable to be transported. Tucker refused to return to Enterprise without Zho'Kaan, and a modified Arkonian shuttle was sent to rescue both of them. (ENT: "Dawn")
