Fan CastingBatman Beyond

The story moves ahead 20 years later to 2039 in Neo-Gotham, a futuristic version of Gotham City, a megalopolis featuring staggering high rises and flying vehicles driven by upper class society. Bruce is now a man in his 70s, living in bitter isolation in Wayne Manor, with no other companion but his guard dog Ace. It is implied by his virtue of continuing to fight crime for as long as possible and ignoring his aging and deteriorating health (he had retained his former partner's costumes) in addition to his obsessiveness that he had suffered a tragic event years prior to his retirement, so is this moment when a new guy called Terry McGinnis became the new Batman.
