Jack Harkness

Appearance
Just over six foot tall, Jack appears to be a human white man in his early thirties, with dark hair and blue eyes. By human standards, he's handsome, broad but not heavily muscled, with a chiseled jaw, cleft chin and infectious grin.

Immortality. Jack can't be killed, but some apparent deaths will take longer for him to recover from. On rare occasions, Jack can share some of his excess life force to keep someone alive until they can receive medical attention.

Talents
Flirting.

Interests
Pretty much everyone and everywhere. Jack can find beauty in almost anything.

History
Jack's life has involved a lot of time travel, which makes it hard for him to  lay it out in any kind of sequential order. He was born and raised on the Boeshane Peninsula, old enough to remember when his homeland was invaded, his father killed and his brother captured.

The relevant bit happened when he met the Doctor and Rose in 1940s London during the Blitz, the Doctor rescued him before his stolen ship exploded, and Jack went on to travel with them for a short time before being killed by a Dalek.

Figuring out that his best chance of finding the Doctor again was heading to early 21st century Earth, Jack got as close as he could, landed in the mid 19th century, worked for Torchwood and eventually ended up heading Torchwood Three, based in Cardiff. A lot's happened, most recently a time slip that landed Jack and his teammate Toshiko back in 1940s Cardiff, in a dance hall where Jack finally met the man whose name he'd taken from the casualty lists. An air raid and a dance later, Jack's 21st century team managed to re-open the rift to bring them back, but while Tosh presumably returned to 21st century Cardiff, Jack's landed on a dust road in a field beside a Wall...
