Theodorus was a soldier in Xena's army when the Warrior Princess was attacking Arcadia. He was in love with Xena and she used his love. Xena sent Theodorus on a suicide mission to kill Hercules because she knew that once Hercules had defeated him, the hero would come looking for her and Iolaus. Indeed, that is exactly what happened. Theodorus planned a sneak attack on Hercules in Alcmene's barn and Hercules killed him in self-defense.
