A huge Orion fighter put forward by D'Erika Tendi in a barter by combat against the Cerritos, who wins by collapsing on Dr. Migleemo in the Lower Decks episode Old Friends, New Planets.
B'eth is an Orion warrior of the Tendi household who appears in Old Friends, New Planets, the fourth-season finale of Lower Decks. With Beckett Mariner in the hands of Nick Locarno and his Nova Fleet hiding behind a Trynar shield, Captain Freeman takes the Cerritos to Orion, where D'Vana Tendi asks her sister D'Erika for a warship.
D'Erika refuses to hand one over for nothing and insists on the Orion custom of barter by combat, with the Cerritos itself staked on the result. Her champion is the enormous B'eth. In the deciding bout the Starfleet side is represented by the ship's counsellor, the bird-like Dr. Migleemo.
B'eth ends the bout by falling on top of her opponent, and Migleemo loses. Tendi rescues the bargain by offering to come home and serve the family, and in return the crew receive a derelict battleship, which Freeman uses to break through Locarno's shield.
