Magh

From Memory Alpha, the free Star Trek reference.

Captain Magh was the commander of a Klingon ship that intercepted Enterprise (NX-01) when it entered Klingon space in search of Arik Soong and his Augments in 2154. Enterprise managed to disable Magh's ship and escape by using the grappler to shear one of the nacelles off his ship. (ENT: "The Augments")
