The character of Xena from Hercules: The Legendary Journeys and Xena: Warrior Princess was introduced with a very extensive backstory; she was a villager who became a warrior by force who became a warlord, and a legend across several continents. Lucy Lawless started playing Xena at 27 years old in 1995.... but that doesn't necessarily mean it was the character's age.
In fact, due to everything that seemed to happen in Xena's personal history, it's highly unlikely that was the characters age!
By a year after she starts traveling with Gabrielle... which was, by most canonical and chronological accounts, 2 years after her first appearance on Hercules: TLJ... we find out Xena has Solen, a 10-11 year old son. This was done during her warlord days, and she left the child to be raised by the Centaurs. But... that would have put her, at most, at 19 when he was born.
I'm a little sketchy on the timeline of the series, but I don't think that lines up; either Xena was supposed to be traveling Asia, or just finishing a war with Caesar at the time. Given that a lot of the story was altered "on the fly" in the series as it progressed, such inconsistencies are to be expected, but...
Is there any canon answer to how old Xena was exactly when she first fought Hercules? Or if not, how old was her character meant to be when she started her Warrior Princess days with Gabrielle?
And considering there were a few time skips, how old would she have been by series end?
