Rachel Caspian: In Batman: Year Two, Bruce Wayne fell in love with Rachel. Unfortunately, Rachel's father moonlighted as a murderous vigilante who committed suicide. Discovery of her father's evils drove Rachel to pay her father's penance on his behalf by enrolling in a nunnery and breaking off her engagement with Bruce Wayne, who had prepared to end his crimefighting career to marry her.
In 1969, Dick Grayson attends college as part of DC Comics' effort to revise the Batman comics. Additionally, Batman also moves from 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 an insane, murderous Joker, and the arrival of Ra's Al Ghul. In the 1980s, Dick Grayson becomes Nightwing.
Batman reformed the Bat-Family with Batwoman and began training Duke to become another vigilante for Gotham. Whilst saving a falling airplane, Batman received help from two new heroes called Gotham and Gotham Girl, two metahumans with powers similar to Superman. Seeing them as a potential replacement for him, he took the duo under his wing and helped them on the path to becoming Gotham's new superheroes. However, after an encounter with Hugo Strange and the Psycho Pirate, the two were rendered mentally damaged and, when Gotham attacked the city, Batman was forced to fight him until his powers drained his body, killing him. Taking Claire under his wing, Batman, with the help of the rest of the Bat Family, stopped an attack orchestrated by Strange, similar to one of their earliest encounters.
Batman was one of the few superhero characters to be continuously published as interest in the genre waned during the 1950s. In the story "The Mightiest Team in the World" in Superman #76 (June 1952), Batman teams up with Superman for the first time and the pair discover each other's secret identity. Following the success of this story, World's Finest Comics was revamped so it featured stories starring both heroes together, instead of the separate Batman and Superman features that had been running before. The team-up of the characters was "a financial success in an era when those were few and far between"; this series of stories ran until the book's cancellation in 1986.

There are a few aspects of Batman that remain consistent. He is the secret identity of the wealthy Bruce Wayne, (usually now called a billionaire because of inflation). He has a butler, Alfred, who knows his identity and who took part in raising Bruce after the murder of his father and mother. Batman has no superpowers, but he’s intellectually gifted and makes use of gadgets, science and well-honed fighting skills and physical strength to defeat his enemies.
Harley Quinn: Best known as "The Joker's Girlfriend", Harley has had occasional romantic encounters with Batman, most notably her kiss with him in the episode Harley's Holiday from Batman: The Animated Series. Recently, in the The New 52, there have been a couple of stories in which Harley became infatuated either with Bruce Wayne or Batman. These attractions appear to be entirely one-sided and Batman has shown no signs of attraction towards Harley.
