The large and slow-thinking brother of Krit, one of Morn's former accomplices, who greets Quark by smashing a painting over his head while searching for a fortune in latinum.
Nahsk appears in Who Mourns for Morn?, played by Cyril O'Reilly.
He and his brother Krit arrive on Deep Space 9 in 2374 after hearing that Morn has died and left everything to Quark. Nahsk supplies the muscle of the partnership. He introduces himself by breaking Morn's matador painting over Quark's head, and spends much of the episode being corrected by Krit for saying too much or grasping too little.
Like his brother, Nahsk took part in the Lissepian Mother's Day Heist and has waited years for the statute of limitations to expire. He is caught up in the cargo bay stand-off in which the four former partners turn on one another, and is arrested by Odo's security officers along with the rest.
