Predator: Badlands

Dek, a Yautja runt, strives to earn the approval of his clan. Despite the warnings from his older brother, Kwei, Dek vows to be the first to successfully hunt the Kalisk on the "death planet," Genna. However, their father, Njohrr, orders Kwei to kill Dek, believing the latter to be weak and can only honor the clan in death. Kwei defies the order and remotely activates his transport ship to take Dek to Genna. As the ship launches, Dek is forced to watch helplessly as Njohrr executes Kwei.
