This is a fan made story I do not own batman or the dc universe. 10 years after the final fight with the Gotham's worst criminal. The batman decided to change something about Gotham. So using his power and his well known ulter ego as Bruce Wayne to encourage an asylum that would actually help Gotham. Bruce also used some of his money and technology to the gcpd could catch the crime lord. So Gotham was at peace and didn't need the batman or the rest of the bat family. Bruce continued to improve Gotham. But there's always a peace before the flood. So fallow the next generation of villains and heros.
