30 Iconic Comics All Batman Fans Must Own
15. Batman: The Dark Knight Returns
This brilliant story sees an ageing Bruce Wayne - who has been retired for ten years - putting the suit back on, as not being an active hero is against his natural instincts.
His return to action causes the Joker to wake from catatonia and a series of events causes the government to order Superman to remove Batman, who must then face-off against his old friend at the age of 55.
