The cautious leader of the Varro generational ship that Voyager helps to repair in 2375, whose distrust of outsiders is tested by Harry Kim's forbidden romance with a member of his crew.
Jippeq appears in the fifth-season Voyager episode The Disease, played by Charles Rocket. He leads the Varro, a people who have lived for about four centuries aboard a vast multi-segmented generational ship and who keep contact with other species to a minimum.
He accepts Voyager's help in repairing the ship's warp drive but insists on strict limits to the cooperation. When he learns that Ensign Harry Kim has become intimately involved with the Varro engineer Tal, he is offended and suspicious, and the affair strains relations with Captain Janeway.
Jippeq then discovers that dissidents among his own people, Tal included, have sabotaged the vessel so that its segments can separate. Faced with the result, he reluctantly lets those who want a different life go their own way.
