Seven of Nine
TV show: “Star Trek: Voyager” (1995 to 2001)
Background: A human assimilated by Borgs as a human child, Seven of Nine was implanted with cybernetic implants and became a part of the Collective. She became Voyager crew member in her early 20s. The Doctor removed the majority of her cybernetic implants and she became more human.
Why we love her: Even though she struggles with human emotions, her ability to sense nearby Borg activity is very useful.
