Copen is a cold, serious person. He is focused on only his goals, and nothing else, willing to kill anyone if they get in his way. He is also incredibly stubborn, firmly rooted in his ideals despite Gunvolt's attempts to reach out to him.

Copen harbors a deep hatred for all Adepts, believing they endanger the planet, and has taken the job of destroying every single one, spurred on by his respect and admiration of his father. His hatred has reached the point where he absolutely refuses to join.
