Face of Boe
A guy who was brought back to life by a girl, couldn't die, and was a smelly ghost for a long time. He finally died because he was too much of a hero.
'He's like a ghost who won't stop bragging about how cool he was.'
'He died saving a city? That's the most idiotic thing I've ever heard.'
'He was back from the dead, but he still had the attitude of a smelly captain.'
