The unnamed Klingon officer who leads three battle cruisers against the V'Ger cloud in the opening scene of Star Trek: The Motion Picture and is destroyed along with his ships.
The Klingon captain commands the IKS Amar, the lead ship of three K't'inga-class cruisers that intercept an enormous energy cloud crossing Klingon space at the start of Star Trek: The Motion Picture.
He orders a spread of photon torpedoes fired into the cloud, which swallows them without effect. V'Ger answers with bolts of plasma energy that dissolve each cruiser in turn; the captain orders evasive action and a rear torpedo but his ship is the last to vanish, the whole engagement being watched by the Federation station Epsilon IX.
The role was played by Mark Lenard, better known as Sarek. The scene introduced both the ridged Klingon forehead and the first spoken Klingon dialogue.
