aka Batman of the Future (1999-2001)
52 episodes, approx 22 minutes each, split over 3 seasons.
The team that created Batman Beyond (aka Batman of the Future) achieved the near-impossible: they made a show that's the equal of Batman: The Animated Series (1992-95) in tone and content and they did it without having Billionaire Bruce Wayne as the lead! Holy personnel changes, Batman.
Even Gotham has evolved, into Neo-Gotham, a towering, high-tech megalopolis wherein crime and corruption is as rife in the shiny office buildings as it is on late night docks.
Bruce (Kevin Conroy) is still around, possibly because like one of his contemporaries said he's too stubborn to die. He is, however, a retired, cranky and cynical recluse that rarely leaves the seclusion and safety of Wayne Manor.
