Captain Jack Harkness
A man with an enigmatic past, Jack leads his team through danger and temptation. The team know very little about this mysterious figure: only that someone with that name disappeared in the middle of the Second World War - but that couldn't be him, could it? Looks late 30s, but probably much, much older, Jack is from the far future but for undisclosed reasons has chosen to head up Torchwood.
The heart of and soul of the team, Jack is pragmatic and practical - if sacrificing a life to save many is the only option, he'll take it. Ambivalent to sexual boundaries, Jack's life remains private.
