Oben was a Cardassian Gul serving House Arterius in the 24th century.
In 2378, he was in charge of the Cardassian fleet at the Voltair system. There, he was responsible for supervising tests on the new Hybrid-class vessels. When these tests were interrupted by the USS Sovereign and IKV Mav'jop, Oben swore to destroy them. Despite his fleet of two Galor-class and two Keldon-class vessels, he was defeated and his ships destroyed. (TNG video game: Bridge Commander)
