Seska

Seska is a fictional alien featured in the Star Trek multimedia franchise. She was a supporting character on the TV series Star Trek: Voyager, where she was played by actress Martha Hackett. She made thirteen appearances on the series in total.

Overview
Seska was a Cardassian, who underwent cosmetic surgery to look a human. She became a spy and infiltrated the terrorist cell the Maquis, under the command of a former Starfleet commander, Chakotay. In 2371, the Maquis ship was overtaken by the Federation ship the USS Voyager NCC-74656. The Voyager was cast into the Delta Quadrant, and both crews had to work together in order to find a way back - a trip that was scheduled to take them seventy years to complete.

Biography
In the beginning, things were very tense between members of the Federation and members of the Maquis, who were all forced to work together as one crew. Tensions increased when former Maquis member B'Elanna Torres punched out Starfleet engineer Joe Carey. Seska and another Maquis member quietly told their commander, Chakotay, that they would support him should he decided to take the ship. To Seska's surprise, Chakotay was quite offended by this, and told them that if he ever heard such talk again, he would throw them in the brig for mutiny. Star Trek: Voyager: Parallax

Seska was then given the rank of Ensign and worked as support staff aboard the Voyger 's bridge crew.
