My name is Captain Jack Harkness.

It's not my real name but I'm proud to use it.

I'm the head of Torchwood. I hire the staff, set the rules, make the decisions, decide which aliens to chase and deal with the outcome.

I used to have a different life, so many years ago.

Then something happened which changed things forever.

I died but I came back to life.

Something, or rather someone, made me immortal.

I've been stabbed, electrocuted, thrown from a roof and shot (on more than one occasion) but each time I've been revived.

I'm the man who cannot die.

So you see Torchwood isn't just my job, it's my life.

I've been at here long enough to know this isn't a job people just retire from.

Eventually my team, my friends, will die.

Defending their planet.

Until the last man.

As true heroes.

I am the ever constant presence in an ever changing world.

I could leave tomorrow. I could fly away across the stars and never return.

But how can I?

They need me.

My name is Captain Jack Harkness.

This is who I am.

Right here.

Right now.

I am Torchwood.
