Xena: Callisto is Xena's arch enemy. At least until she impregnates her. You heard that correctly. The actress's name is Hudson Leick, yes, like Hudson Lick. At one time she was in Xena's body and the first thing she did was feel herself up all over and have sex with Ares. She said she was angry at Xena about the whole burning her village thing, but I think most of her rage was centered around the fact that her breasts were smaller than Xena's.
