Character from Star Trek played by Denise Crosby. USS Enterprise-D chief of security under the command of Captain Jean-Luc Picard.

Ukrainian in descent, Yar was born on a failed Federation colony on the planet Turkana IV. Her parents were killed when she was only 5. One of the few "normal" aspects of her childhood was her ownership of a pet kitten that she protected.

As a Starfleet officer, she impressed Picard with her courage in rescuing a wounded colonist, making her way through a Carnellian mine field.

Yar was killed in late 2364, while participating in a rescue mission on planet Vagra II, to save Counsellor Deanna Troi.
