Beam Me Up, Scotty! The Hottest Women Who Have Appeared On Star Trek

Bibi Besch as Carol Marcus

Dr. Carol Marcus was a molecular biologist who had a thing for Captain Kirk. She liked the Captain so much, she had a child with him named David Marcus. After their relationship, Dr. Carol Marcus decided that her duty as a mother and her work as a molecular biologist was more important than her relationship with Captain Kirk (seriously, snaps for Marcus for empowering young women everywhere).

Bibi Besch played the original Dr. Carol Marcus, and actress Alice Eve played the updated version of the character. In the series, Dr. Marcus finds out that her father was a part of the original fleet and had a very dark side to him.
