Biography
Jack Harkness is an immortal human originally from 51st century Boshane Peninsula. His real name is unknown. He was recruited into the Time Agency, but left when he discovered that they had taken two years of his memory. He became a time traveling con man, running scams with his knowledge of future events. He met the Ninth Doctor, Lilith and Rose Tyler in London, 1941 and joined them after they stopped a nanogenes from inadvertently destroying the human race due to an accident with a dead child named Jamie. Jack was first killed by Daleks in the year 200,100 during an attack on the Game Station, but was permanently brought back to life by Rose Tyler wielding the Time Vortex. Jack was made a fixed point in time due to Rose being unable to control the power of the Vortex, meaning that he cannot stay dead. He used his vortex manipulator to try to return to the 21st century, but he ended up stranded in 1896 when his manipulator burnt out. He stationed himself in Cardiff, Wales, working for Torchwood III and waiting for the Doctor to show up again. When the Tenth Doctor, Lilith, and Martha Jones came to Cardiff to refuel the TARDIS in 2008, Jack grabbed onto the ship, which took them to the year 100 trillion. Events led to Jack being kept on there Valiant during the Year That Never Was, being tortured and killed constantly by the Master. After time reset, Jack decided to stay with his Torchwood team instead of traveling with the Doctor again. Jack was a part of the Doctor’s Children of Time and helped defeat the Daleks when they invaded Earth and transported the planet to the Medusa Cascade in 2009. Rose and the Doctor named Jack Lilith’s godfather when she was born. A few years after Lilith returned to her proper timeline, she sent Jack back to the Library in order to rewrite time and prevent River Song’s death. Jack ended up marrying River, and they have a two-year-old daughter, Amelia Rose Harkness.
