SPOILER: Because the series was canceled, the producers had no way to finish the story because the first season ended with a cliffhanger. Interest in the ongoing comic series had also waned, and it was canceled as well. Thanks to the warning the comic-book writers had received, they were able to write a 2-part story that served as the official ending for both the TV series and the comic-book series: the Leader sends his only child to Earth, who is befriended by the resistance. In spite of the war-minded Visitors plotting an assassination attempt to frame the humans, he was returned safely to the leader, and as a gesture of thanks, he recalled the attacking fleet from Earth.
