Which actor played Dr. Carol Marcus in Star Trek II: The Wrath of Khan?

Bibi Besch played Dr. Carol Marcus in Star Trek II: The Wrath of Khan.

Carol Marcus is a brilliant Federation scientist and one of the principal researchers behind the Genesis Device, a technology designed to transform an inhospitable world into a habitable one. She is also the mother of David Marcus, James T. Kirk’s son, giving the film’s scientific conflict a personal dimension for Kirk.

Besch’s performance presents Carol as an accomplished scientist who has built a life separate from Kirk. The film gradually reveals their past relationship, while Carol initially uses the surname Marcus and maintains emotional distance from him. Her work on Genesis becomes dangerous when Khan and the Klingons seek to exploit it as a weapon.

The alternative answers are associated with other Star Trek roles. Kirstie Alley played Lieutenant Saavik in The Wrath of Khan, Denise Crosby played Tasha Yar on Star Trek: The Next Generation, and Kate Mulgrew played Captain Kathryn Janeway on Star Trek: Voyager. Bibi Besch appeared in the 1982 film and died in 1996.
