Which American TV series follows the infamous warrior with a dark past, sets out to redeem herself?

Loved the show !

definitely not Lucy Lawless in the picture oh, so I thought it must be something else

I watched Hercules and Xena but don't remember "a dark past"

TestyAlien3443, same. That’s what threw me off

XENA WAS SO U USUAL AND FEATURED THIS AMAZING FEMALE PROTAGONIST. MY FAMULY WAT HED THE SHOW AND RERUNS. WE NAMED OUR DOG XENA. BUT SHE WAS A PRINCESS, NOT A WARRIOR.

Lucy Lawless starred as Zena, is also a sister to Blackie Lawless of the heavy metal band W.A.S.P.
