Jarvin was a Maquis fighter who served on the raider the Val Jean under Chakotay until 2371. In 2371 the Val Jean and the USS Voyager were both stranded in the Delta Quadrant by the Caretaker's array. The Val Jean was destroyed by ramming a Kazon warship while fighting the Kazon-Ogla, as a result the crew of the Val Jean, Jarvin included, joined the crew of the Voyager as Starfleet personnel and traveled onboard Voyager during its historic trek home through the Delta Quadrant. (VOY: "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. Chakotay was not impressed and threatened to throw Jarvin in the Brig for mutiny. (VOY: "Parallax")
- Jarvin was played by Justin Williams.
