A Klingon lower decker who killed his treacherous captain, took command of the Che'Ta' and became an unlikely ally of the Cerritos.
Ma'ah began as a lower decks officer aboard the Klingon Bird-of-Prey IKS Che'Ta'. When he learned that his captain, Dorg, was secretly arming the Pakleds for an attack on Earth against the wishes of the High Council, he challenged Dorg, killed him in combat and took command. He is voiced by Jon Curry.
Later his crew was among those that mutinied under Nick Locarno's influence. Stranded alongside Beckett Mariner, Ma'ah helped restore her faith in herself and Starfleet before they retook his ship, but he was stripped of his command afterward. Dorg's brother Bargh blocked his appeals until Ma'ah killed him with Brad Boimler's encouragement.
Ma'ah then set out with his brother Malor, sheltered aboard the Cerritos from Dorg's vengeful sister Relga, and helped save the prime universe from a dimensional rift. The High Council rewarded him with command of Relga's fleet.
