Discord

Discord or Eris is the goddess of discord. She is Ares' sister and a daughter of Zeus. Discord often assists Ares in his plots against their half-brother Hercules. Eris is not only the sister of Ares but also his flunky and lover.

Being a lesser god, Discord never really became a big deal but as Goddess of Chaos did her job well. Also becoming a thorn in the side of Xena, Ares gave Discord a chance to be Goddess of Retribution after Nemesis, but she was given her original title back.

During the Twilight of the Gods, Discord along with the other Olympians attempted to kill Xena and her daughter Eve but Xena, imbued with the power to kill gods, chopped her head off.
