A fiercely competitive pilot in the Antarian Trans-stellar Rally of 2377, whose belligerent manner makes him an obvious suspect when the race is disrupted by sabotage.
Assan appears in the seventh-season Voyager episode Drive, played by Patrick Kilpatrick. He is one of the entrants in a race held to celebrate a newly signed peace between four formerly warring species of the region.
From the outset he treats the event as a continuation of the old conflict, sneering at rivals and crowding the Delta Flyer, entered by Tom Paris and B'Elanna Torres, during the opening legs. When an explosion injures the co-pilot of the racer Irina, suspicion falls naturally on him.
Assan is in fact innocent of that plot. The saboteur is Irina herself, who means to wreck the peace by destroying the leading ship at the finish, and Assan is left simply as one of the competitors beaten when the race is completed safely.
