Following Infinite Crisis, Bruce Wayne, Dick Grayson (having recovered from his wounds), and Tim Drake retrace the steps Bruce had taken when he originally left Gotham City, to "rebuild Batman". In the Face the Face storyline, Batman and Robin return to Gotham City after their year-long absence. Part of this absence is captured during Week 30 of the 52 series, which shows Batman fighting his inner demons. Later on in 52, Batman is shown undergoing an intense meditation ritual in Nanda Parbat. This becomes an important part of the regular Batman title, which reveals that Batman is reborn as a more effective crime fighter while undergoing this ritual, having "hunted down and ate" the last traces of fear in his mind. At the end of the "Face the Face" story arc, Bruce officially adopts Tim (who had lost both of his parents at various points in the character's history) as his son. The follow-up story arc in Batman, Batman and Son, introduces Damian Wayne, who is Batman's son with Talia al Ghul. Although originally in Son of the Demon, Bruce's coupling with Talia was implied to be consensual, this arc ret-conned it into Talia forcing herself on Bruce.
Winding up in Gotham City, Bane exhausted Batman by freeing all the villains from Arkham Asylum. He then crippled the Dark Knight by snapping his spine. Jean Paul Valley (Azrael) donned the Batman garb ? wile Bruce recuperated from his injuries. This interim Batman was more violent and unstable; Bruce returned to action as soon as his body had healed and he had regained his fighting spirit, with the help of ruthless martial-arts mistress Lady Shiva. Bruce took back the mantle of the Bat by force.
Starting with Batman vol. 2, #41, Commissioner James Gordon takes over Bruce's mantle as a new, state-sanctioned, robotic-Batman, debuting in the Free Comic Book Day special comic Divergence. However, Bruce Wayne is soon revealed to be alive, albeit now suffering almost total amnesia of his life as Batman and only remembering his life as Bruce Wayne through what he has learned from Alfred. Bruce Wayne finds happiness and proposes to his girlfriend, Julie Madison, but Mr. Bloom heavily injures Jim Gordon and takes control of Gotham City and threatens to destroy the city by energizing a particle reactor to create a "strange star" to swallow the city. Bruce Wayne discovers the truth that he was Batman and after talking to a stranger who smiles a lot (it is heavily implied that this is the amnesic Joker) he forces Alfred to implant his memories as Batman, but at the cost of his memories as the reborn Bruce Wayne. He returns and helps Jim Gordon defeat Mr. Bloom and shut down the reactor. Gordon gets his job back as the commissioner, and the government Batman project is shut down.
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.
