Koral was a male Klingon mercenary in the 24th century. He piloted a Toron-class shuttlecraft.
In 2370, Koral had acquired the second piece of a Vulcan artifact (the Stone of Gol) and had arranged to rendezvous with Arctus Baran in the Hyralan sector. Despite being free to travel there, his shuttle was detained by the USS Enterprise-D for "health and safety inspections." While Beverly Crusher and Worf inspected Koral's ship, he was taken to the observation lounge with Deanna Troi and Data. Koral didn't engage them in conversation, and even declined an offer of bloodwine by pouring it out, making them uncomfortable. Just then, Jean-Luc Picard and William T. Riker, acting under the employ of Baran, beamed in to the room. Picard took the artifact from Koral and left. (TNG: "Gambit, Part II")
Koral was played by basketball hall of famer James Worthy.
At six feet, nine inches tall, he is one of the tallest people ever to appear in a Star Trek production. For this reason, in Q's Guide to the Continuum, a caption in one of the articles says "If you've said Koral, you've said it tall", a reference to Worthy's height.
