Despite being only able to communicate through Pilot (with one exception), Moya has her own personality which can be seen to develop and change through the series. At the beginning of the series she is timid, starbursting to escape the slightest danger at a moment's notice. When she meets the Leviathan gods, the Builders, and they order her death for having produced Talyn, she is willing to die, and is only saved when the order is revealed to be a test for Zhaan. By the end of the second season, she is willing to join the effort to rescue Crichton from Scorpius despite her fears, and is severely damaged in the attempt. At the end of the third season, she asks the crew to kill another Leviathan who is disturbing the burial of her child's remains. And in "The Peacekeeper Wars", this previously timid and peaceful creature trusts the crew enough to allow Crichton to use her to launch the deadly Wormhole Weapon.
