Atul

From Memory Alpha, the free Star Trek reference.

Atul (played by Dennis Madalone) was a Klingon Intelligence operative in the 24th century. Atul, along with Bo'rak and Morka, were sent to Deep Space 9 in 2371 by Chancellor Gowron to observe a Romulan delegation being briefed on Dominion intelligence. Their true identity was eventually revealed and they were arrested by Odo. (DS9: "Visionary")
