The commander of a mining operation that in 2378 orders a colony of Talaxian settlers to abandon the asteroid they live in so that it can be broken up for ore.
Nocona appears in the seventh-season Voyager episode Homestead, played by John Kenton Shull. His miners hold a claim to an asteroid field, one of whose larger bodies shelters several hundred Talaxians who settled there years earlier.
He considers the Talaxians squatters and has no patience for their appeals. An earlier confrontation with his men cost the life of the husband of the settler Dexa, and he gives the colony a short deadline to leave before demolition charges are set off.
Captain Janeway's attempt to mediate wins only a modest offer of help with relocation. Nocona presses ahead, and it is Neelix, flying his own small ship to place shield emitters on the asteroid, who stops him. With Voyager's Delta Flyer covering Neelix, the miners are forced to accept that the settlement will stay.
