B'Elanna Torres is a main character in Star Trek: Voyager played by Roxann Dawson. She is portrayed as a half-human half-Klingon born in 2346 on the Federation colony Kessik IV. She was admitted to Starfleet academy but dropped out before graduating. Torres joined the Maquis in 2370 and was serving on the Val Jean when taken to the Delta Quadrant by the Caretaker alien using his station. After being used for medical experiments she was left in an Ocampa colony maintained by the same alien that had abducted the Val Jean. That ship was destroyed in a space battle at the Array and she and what remained of that crew joined the USS Voyager. On the ship she was given field commissioned rank of Lieutenant, junior grade and posted in engineering. In 2371, she was promoted to Chief Engineer. In 2377, she married Tom Paris and gave birth to their daughter Miral at the beginning of the next year, while Voyager was returning to the Alpha Quadrant.
