beginning of the series. He lost his mother when he was young, but often reminisces about the beauty of Earth. He is rebellious (especially against authority), quick-tempered, insensitive, and impulsive, the opposite of his father, who is calm and thoughtful. His nonattendance at the compulsory military exam leads to him and Mike being chased by the military police into the area where the spaceship crash lands. At first, Joe attempts to leave his friends in order to go after Hazzard, but they support him when Hazzard imprisons his father and Jenny's parents.

She is a no-nonsense girl-next-door, determined, stubborn, but also caring about her family who faces Hazzard's machinations. She is the second of the group to
