Xepheer Xeneeth was recruited by Drew Greyhelm into the Strikeforce a year before the Battle of Endor. Prior to that, he was associated with fellow member Ham Slacker in an untold adventure that will probably never be known to others.

Xepheer was tall, slender, with angular facial features. He had dark, wild hair, pasty-white skin and his skills with blades were remarkable. He rarely fought with a blaster. Instead he utilized a set of six knives (some were normal knives and some were vibroblades) in combat, wearing four in a bandoleer and one hidden in each sleeve sheath.

He also carried an electric guitar with him on every mission. Whenever the need arose, he sang for his supper in cantinas, cafes and bistros while his teammates sat at a table enjoying a meal and the song.

When he first joined the Strikeforce, he discovered that his old friend Ham Slacker had been captured by Imperials and was incarcerated in Gamma Complex on the penal world of Graynor. He made it his responsibility to rescue his friend in a daring solo mission.

He also helped Shanna Toarinar hunt down the Twi'lek assassin Dik Foranay who had poisoned Shanna. In the skirmish on Endor during the Battle of Endor, he was wounded by AT-ST fire, but his inteference gave Shanna the opening she needed to take down Dik Foranay.

After cleaning up the Enteague Sector after the death of Drew Greyhelm, he disappeared. Only when the Dark Lady Lumiya and the Nagai invasion force was reported on Kinooine soon after the disbanding of the Strikeforce did everyone realized that Xepheer Xeneeth was a Nagai! But there was no proof that he had been a Nagai spy.

He reappeared four years later, aiding Phoenix Avalon and Athala Navin in rescuing Gran school children from a marauding Imperial Star Galleon captain on Kinyen.
