A Voth officer sent to find the fugitive scientist Forra Gegen, whose pursuit ends with Voyager itself being captured by an enormous Voth city ship.
Haluk is a commander in the service of the Voth, the saurian species that believes itself to be the first race of its region. He appears in the third-season Voyager episode Distant Origin.
When Professor Gegen flees rather than recant his theory that the Voth came from a distant planet, the Ministry of Elders orders him brought back. Haluk leads the search and follows Gegen's trail to Voyager.
Voth technology hopelessly outclasses the Starfleet ship, which is beamed whole into the city ship and overrun by boarding parties using personal cloaks. Haluk then delivers Gegen and the crew to Minister Odala, before whom the professor is finally forced to deny his findings.
