Ensign Brooks was a command division Starfleet officer aboard the USS Voyager, under Captain Kathryn Janeway. She was one of many crewmembers that survived the transport to the Delta Quadrant in 2371.
Brooks was among the crewmembers who were transported onto the Caretaker's array shortly after Voyager was lost in the Delta Quadrant. Alongside another officer, she scanned the region at captain's orders. (VOY: "Caretaker")
In 2373, she greeted The Doctor while she passed sickbay. The Doctor, who was at the time malfunctioning, began to follow Brooks as she made her way to the turbolift. Unknown to her at the time, as Brooks traveled aboard the turbolift to Deck 10, The Doctor stood behind her plotting his move of malcontent against her. Fortunately, Brooks was saved when Tom Paris entered the turbolift and unknowingly interrupted The Doctor's plans. (VOY: "Darkling")
In 2378, Brooks attended the First Contact Day party in the mess hall and stood later in the hallway with much of the rest of the crew to bid farewell to Neelix when he left the ship for good. (VOY: "Homestead")
Further appearances and references
Ensign Brooks was portrayed by Sue Henley, the regular background actress and stand-in for Kate Mulgrew. Although making several appearances, she was only credited twice, in "Darkling" (as Ensign) and in "Year of Hell, Part II". Henley previously portrayed a command division officer in the second and third season of Star Trek: Deep Space Nine.
According to an interview with Henley, she did little background work on the first season because of her strong likeness to Mulgrew. Occasionally she wore a wig, which she described as a "hideous black dead-rat-looking wig".
