A Klingon general whose warships arrive to destroy a subspace fold in the episode Subspace Rhapsody and whose crew are forced to burst into song with everyone else.
General Garkog appears in the second-season Strange New Worlds musical episode Subspace Rhapsody. He is played by Bruce Horak, who had been Hemmer in the first season.
An experiment with a naturally occurring subspace fold creates a field in which people sing their feelings aloud, and the effect spreads along the subspace network as far as the Klingon Empire. Garkog, humiliated, brings his ships to destroy the fold by force, which the Enterprise crew calculate would do enormous damage.
Pike has to keep him talking while his people prepare a grand finale big enough to collapse the field. When Garkog's ship is hailed during the closing number, he and his warriors are seen performing a slick pop routine, to his evident disgust. With the field gone he departs, declaring the affair a dishonour.
