Captain Jack Harkness

Once a con man and Time Agent from the 51st century, Captain Jack Harkness is notorious for flirting with anyone attractive. He’s an old friend of the Doctor, made immortal when Rose Tyler (the Doctor’s fisrt companion after the Last Great Time War) became a nigh-omnipotent being with no control over her powers, thus bringing him back to life after a Dalek killed him. This led to him discovering he was an immortal after the Doctor and Rose left him on the station he first died in. He then tried to pursue the Doctor with his vortex manipulator, but ended up in the 20th century and wormed his way into history, serving in both World Wars. He then took command of Torchwood 3 and camped himself near a rift in Cardiff, Wales. He then reunited with the Doctor in a new body and had a few adventures with him. After a while, the Doctor and Jack stopped meeting for long periods of time until the Doctor was in her first woman body. These days, he and the Doctor arrived at Beyond City after an adventure went wrong and forced the Doctor to regenerate again. Jack’s making his acquaintance with the Vortex Riders, the Autobots and their allies, and Arsha and her friends and family. He’s going to be needed once the Author makes his presence known.
