10 Doctor Who Characters Who Can Never Die
5. Captain Jack Harkness
Arguably the most famous immortal in Doctor Who history, Captain Jack Harkness certainly put his powers to the test in the years after the Bad Wolf gave him them.
He's been shot in the head, deleted by a Cyberwoman, exterminated by a Dalek, and pushed off a building, but perhaps his most memorable "death" occurred in Doctor Who's third series finale, where he rode the TARDIS into the Time Vortex, and managed to cling on all the way to the end of the universe.
Ah, Jack. Always the show-off.
Though it's impossible to kill him with bullets, bombs, and other traditional weapons, we have technically seen Jack die for good. As much as some fans still believe this isn't the case, Russell T Davies reaffirmed in a 2020 tweetalong of New Earth and Gridlock that Jack is indeed The Face of Boe. So, when Boe slips away at the end of Gridlock, we're also saying farewell to everyone's favourite flirty Time Agent.
Still, for all intents and purposes, the Captain Jack Harkness we all know and love can never truly die. When it takes five billion years and a transformation into a pickled head to kill you off... you know you're quite the badass.
