Of the 4 incarnations of the Hercules Universe {Young Herc, Herc, Xena, & the Animated Movie} Xena is undoubtedly my favorite, & the reason that I subject myself to any of the others...lol. Xena is strong & flawed, obviously bisexual, & a wonderful role model.
Xena first appeared in a trio of Herc episodes: "The Warrior Princess", "The Gauntlet", & "Unchained Heart", before she was given her own series. Both Xena & Gabrielle were featured in the Herc episode "Judgment Day", while alternate versions of them appeared in "Stranger In A Strange World" & "Armaggedon Now, Part II". Other characters & plot lines bounced back & fourth between the two series & while it is possible to enjoy both series individually - they compliment each other & their stories are richer because of it.
Here I've listed the episodes of the Xena: Warrior Princess television series, which at the time of this posting has not yet finished it's 6th & final season. This is the order I believe the episodes should be viewed in:
