David Spangler is a man whose life is filled with resentment and anger. Beginning with his replacement on the Atlantis shuttle mission by Jack when the powers who made those decision opted not to risk two family members, David learns to resent Jack. When his sister Jennifer is killed on that fated shuttle mission meant to launch the satellite Spartacus, David nurtures that resentment into hatred. Consumed by it, he bides his time, always looking for a way to get even. David is tall, broad shouldered and has a muscular frame. He has blond hair cropped close and is well tanned.
