The co-pilot of the racer Irina in the Antarian Trans-stellar Rally of 2377, whose injury in an explosion aboard their ship leads Harry Kim to take his seat.
Joxom appears in the seventh-season Voyager episode Drive, played by Robert Tyler. He flies with Irina, a pilot Tom Paris meets shortly before the rally and whose talk of the event persuades Voyager's crew to enter the Delta Flyer.
Early in the race a console on Irina's ship explodes, badly burning Joxom. He is treated in Voyager's sickbay, and Tuvok's examination of the wreckage shows that the blast was caused deliberately rather than by a fault.
With Joxom unable to continue, Harry Kim volunteers to fly as Irina's co-pilot. That brings him close enough to discover that she is the saboteur and has rigged the Delta Flyer to blow up at the finishing line, wrecking a peace she opposes. Joxom himself appears to have known nothing of her plan.
