Janice Lester

Doctor Janice Lester was a female Human in the 23rd century.

Early in her carrier Lester served in Starfleet along side James T. Kirk, whom she had a relationship with. She left Starfleet having perceived a level of sexism in the organisation which she believed would prevent her ever obtaining the goal she so desired, commanding a starship.

By 2269 Lester was leading an expedition to the planet Camus II, there she discovered a device capable of transferring a consciousness between bodies. Seeing this is as an opportunity she went about learning the intricacies of Starfleet operations before conspiring with the expedition’s physician Arthur Coleman to murder the rest of the expedition, as a means of drawing the USS Enterprise to the planet when then sent a distress call out seeking assistance after all the mysterious deaths.

The ruse worked and a landing party from the Enterprise transported down to investigate. Lester used the alien device to transfer her and Kirk's souls, but failed to kill her body containing Kirk's mind, which would have resulted in her parentally holding Kirk's body, before Dr McCoy turned up.

Lester in Kirk's body and visa-versa the team returned to Enterprise where Lester took command. She successfully played Kirk for a time but eventually clues began to make the crew suspicious and as Lester made an attempt to kill Kirk in her old body the consciousness’ transferred back. (TOS episode: Turnabout Intruder)

A week later Enterprise transferred Lester into the custody of Starbase 2 where she awaited charges and transfer to Elba II. (TOS comic: "Captain's Personnel Log")
