He is the son of a warlord and musician. He is second of the triplet children, which he wishes he never had. One, Jett, is the King of Assassins. The other, Jace, the latin singer.
Joxer tries to prove himself to others but no one would take him in, not even Xena. When he tries to serve the evil warlord, Callisto, he was sent to kidnap Xena's companion, Gabrielle. He failed, and trying to save her, Callisto captured both him and Gabrielle.
Joxer appeared again when Aphrodite, the Goddess of Love, had made him a romantic warrior, whom had stolen the heart of a princess so the merge of two kingdoms would not demolish her temple.
As time went on, Joxer became a loyal and good friend to Xena and Gabrielle. He even befriended Hercules and Iolaus.
When Xena and Gabrielle were crucified by Julius Caesar, Joxer, along with Amarice and Eli, tried to get them out of Rome and have them buried in Greece. FOrtunately, he reconsidered when the two female warriors had returned to life. Joxer admitted to Gabrielle that he was in love with her. But when noticing that Gabrielle wasn't in love with him, he set his eyes on Xena's double, Meg, a ditzy harlot.
When Xena and Gabrielle had faked their deaths in the eyes of the Olympian Gods, Joxer searched for their bodies when Ares had them buried in a icy tomb. He then moved on with his life, twenty-fives years later, as he married Meg, started a tavern dedicated to the Warrior Princess and the Battling Bard, and had three children; his eldest Virgil, the poetic warrior, and a boy and a girl whom are unknown.
Discovering that Xena and Gabrielle were alive, he traveled with them again, in search of Eve, Xena's daughter. Eve was actually the Roman tyrant, Livia. Trying to save Gabrielle, Joxer was stabbed in the stomach by Livia.
In the future, Joxer has a american descendant that was responsible for the creation of the Xena Warrior Princess television series. He is reincarnated as a Xena/Joxer fan, Annie Day, who is in the form of Xena.
