In 1969, Dick Grayson attends college as part of DC Comics' effort to revise the Batman comics. Additionally, Batman also moves from his mansion, Wayne Manor into a penthouse apartment atop the Wayne Foundation building in downtown Gotham City, in order to be closer to Gotham City's crime. Batman spends the 1970s and early 1980s mainly working solo, with occasional team-ups with Robin and/or Batgirl. Batman's adventures also become somewhat darker and more grim during this period, depicting increasingly violent crimes, including the first appearance (since the early golden age) of the Joker as a homicidal psychopath, and the arrival of Ra's al Ghul, a centuries-old terrorist who knows Batman's secret identity. In the 1980s, Dick Grayson becomes Nightwing.
After revealing this knowledge to the original Dynamic Duo, Tim argued the need for a Robin to give the Dark Knight hope, especially when faced with a seemingly hopeless and unyielding war on crime. Though reluctant at first, Batman gave Tim the opportunity to prove that he was as good as his word. After months of grueling training, Tim Drake became the third Robin.
It's funny, with how bad his costume ended up looking, it made the original Batman costume that Jean-Paul came up with for Batman look almost tame in comparison. However, it's still a pretty strange look. When Jean-Paul first took over as Batman, he just wore the traditional Batman costume. He then added some special claw gloves. However, when it came time to take on Bane one-on-one, Jean-Paul decided that he needed a lot more protection (after all, Bane had just broken the back of his predecessor).
Reviving in a hospital in the 1930s, Bruce meets Marsha, a woman who claims that she wants to employ him as a detective to investigate the death of her friend, Martha Wayne, providing him with a 1930s suit to wear as he carries out his investigations. Meeting with Martha's parents, Bruce learns of Thomas Wayne's apparent infidelity and his connection to various orgies, but remains suspicious that he is not being told the whole truth. After Wayne is provided with a Bat-costume to wear during the final stages of his investigation- the same costume worn by Thomas Wayne long ago-, he tracks 'Marsha' to a graveyard, where it is revealed that she is a member of the Black Glove, who believes that she will be granted eternal youth if she ritually sacrifices the 'Bat-Man', having selected the amnesiac Bruce as the perfect sacrifice as nobody will miss him. Despite his confusion and weakness, Wayne fights off the Black Glove before Carter Nichols's time machine teleports him to the end of time, leaving the Glove without a sacrifice. Bruce returns to the JLA Watchtower as a twisted cybernetic Batman.
