List of Minor Recurring Characters in Star Trek: The Next Generation - Alyssa Ogawa

Alyssa Ogawa, played by Patti Yasutake, is a character in the fictional Star Trek universe. The character appears in Star Trek: The Next Generation and the film Star Trek Generations as a nurse aboard the USS Enterprise-D and in Star Trek: First Contact as a nurse aboard the USS Enterprise-E.

She joins the USS Enterprise-D in 2367 as an ensign in the medical department. In 2370, upon recommendation of Dr. Beverly Crusher, she is promoted to lieutenant junior grade (TNG: "Lower Decks"). She marries Lieutenant Andrew Powell in that year. Shortly after she reveals she is pregnant, Ogawa reports to the senior staff when an injury incapacitates Crusher (TNG: "Genesis"). She was still pregnant by the series finale (TNG: "All Good Things..."), and her baby's birth was never shown or referred to on television; while said finale depicted her losing her unborn baby due to the effects of an "anti-time" anomaly, this was part of an alternate timeline that Captain Jean-Luc Picard ultimately prevented from coming to pass. In an alternate timeline in the episode 'Parallels', she makes a brief appearance as the ship's doctor with the apparent rank of Commander.

According to the non-canon Star Trek: Titan book series, Ogawa works in Titan's sickbay. She married Andrew Powell on Enterprise D. Powell was killed at the Battle of Rigel during the Dominion war. Ogawa and her young son transferred to the USS Titan under command of Captain Riker to serve in the sickbay.
