Jarvin was a Maquis fighter who served on the raider the SS Zola under Chakotay until 2371. In 2371 the SS Zola and the USS Voyager were both stranded in the Delta Quadrant by the Caretaker's array. The SS Zola was destroyed by ramming a Kazon warship while fighting the Kazon-Ogla, as a result the crew of the SS Zola, Jarvin included, joined the crew of the USS Voyager as Starfleet personal and traveled on the USS Voyager on its historic trek home from the Delta Quadrant. (VGR: "Caretaker")
Later that year Jarvin heard of an altercation between B'Elanna Torres and Joe Carey (both engineers) and grew concerned of the future of the Maquis. He said that he would support Chakotay if he ever planned to take over Voyager. (VOY: "Parallax")
Jarvin was played by Justin Williams.
