During the 1950s, the "Batman" titles were very much the second-class citizens of the DC Comics line of superhero books. In fact, the "DC" aspect of the company's name (which was named after "Detective Comics," where Batman debuted) was rarely as de-emphasized as it was in this era, when the "DC Bullet" featured DC in the center of the logo circle but Superman at the top of the circle and National Comics on the bottom (talk about a cluttered logo). Batman's stories were mostly just riffs on ideas used in Superman comics of the era (Vicki Vale as their Lois Lane, Bat-Mite was their Mr. Mxyzptlk, etc.)
Batman is reawakened by a girl named Harper Row, who he abruptly leaves. Returning to the Batcave, Batman finds the Talon's dead body, which Alfred and Nightwing had retrieved for Batman, who decides to examine it. Later, Nightwing meets up with Bruce, who reveals that the Talon is actually William Cobb, Nightwing's great-grandfather and that Nightwing was destined to be a Talon, a goal stopped by his adoption. The Court recovers from their encounter and decides to activate a small army of Talons they have decommissioned throughout the years.
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.
Diana and Bruce briefly dated but nothing came of their relationship and the two decided it would be best to remain friends. However, they still care deeply about one another, and this is evidenced by Wonder Woman's love for Batman allowing her to become a member of the Star Sapphire Corps in Blackest Night. Their relationship is echoed in the Justice League Animated Series, where producers decided to pair Diana with Bruce.
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.
