Relga is the sister of Dorg and Bargh, who hunts Ma'ah and his brother with her fleet until her ship is destroyed by a rift.
Relga is a Klingon commander and the sister of Dorg and Bargh, both killed by Ma'ah. Determined to avenge them, she pursues Ma'ah and his brother Malor in The New Next Generation, forcing them to seek refuge aboard the Cerritos.
Relga's fleet attacks the Cerritos near the interdimensional rift. Ensign Olly uses her powers to drain the shields of Relga's ship, which is then destroyed by the rift. Because of Relga's dishonorable actions, the Klingon High Council grants command of her fleet to Ma'ah.
