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. While Zho'Kaan was on the moon's surface, his language couldn't be fully understood by Tucker, as he didn't have a universal translator with him. Although Tucker attempted to repair a transceiver from the shuttlepod in order to contact Enterprise NX-01, Zho'Kaan attacked him and stole the transceiver in order to contact his own ship. Zho'Kaan captured Tucker and demanded that he fix the transceiver, but 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 type of fluid from Zho'Kaan's own mouth. Together, they took the transceiver to higher ground to contact their ships.
During the trip, Zho'Kaan became dehydrated and consequently began suffering from acute cellular degradation; this 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. Once they could be fully understood by each other, Zho'Kaan let Tucker know he was grateful not to have killed him. (ENT: "Dawn")
