A Klingon brigadier who serves as military adviser to Chancellor Gorkon and then to his daughter Azetbur during the peace initiative of 2293 depicted in Star Trek VI: The Undiscovered Country.
Brigadier Kerla is played by Paul Rossilli in Star Trek VI: The Undiscovered Country. He accompanies Gorkon aboard the USS Enterprise for the uneasy state dinner, where he spars with Kirk's officers over whether the Federation's talk of rights is anything more than a human club.
After the attack on Kronos One and the chancellor's death, Kerla is among those who confront Kirk and McCoy, and he afterwards presses Azetbur to strike while the Empire still has the strength to win a war. She refuses and holds to her father's course.
Kerla attends the Khitomer conference with Azetbur and is present when the Enterprise and Excelsior crews stop the assassination attempt and expose the conspiracy.
