He then decided to form an international group of Bat-operatives called Batman Incorporated. While he was busy setting this up, he let Dick Grayson (who had taken over when he thought Bruce was dead) remain as Batman in Gotham City. He also got a new costume to differentiate himself from Dick's costume. It had a lot of piping and a protruding, glowing yellow oval; future artists tended to tone down almost all of its elements.
Batman's history has undergone many retroactive continuity revisions, both minor and major. Elements of the character's history have varied greatly. Scholars William Uricchio and Roberta E. Pearson noted in the early 1990s, "Unlike some fictional characters, the Batman has no primary urtext set in a specific period, but has rather existed in a plethora of equally valid texts constantly appearing over more than five decades."
Back in the 90s comics were prone to some wild publicity stunts to sell issues. The most notable events were the Death of Superman and a villain known as Bane breaking Batman's back. This forced Bruce Wayne to pass the mantle of Batman on to a man named Jean-Paul Valley. Valley ended up going a little crazy. He did not adhere to Batman's rule of "no killing" and made a lot of deadly modifications to the Batsuit. When Wayne got word of Valley's methods and Bane's crime-spree, he went on a spirit journey similar to his first quest to become Batman.
Comic book companies often look at costume design as "the more changes, the better." Batman is a character who had one of the most famous costume changes in comic book history (albeit just by adding a simply yellow oval), but otherwise managed to only go through a handful of looks in the 20th Century. In the 21st Century, though, Batman has gone through as many costumes as he had in the first 50 years of his existence, and more new looks are undoubtedly coming in the future!
The movie which a young Bruce and his parents were seeing on the night of their murder is generally stated to be "Mark of Zorro" (the exact version varies). This is important because Bob Kane stated that he drew inspiration for Batman from seeing a screening of that very movie. He also drew inspiration from images of Leonardo da Vinci's flying machine.
DC's 2005 limited series Identity Crisis, reveals that JLA member Zatanna had edited Batman's memories, leading to his deep loss of trust in the rest of the superhero community. Batman later creates the Brother I satellite surveillance system to watch over the other heroes. Its eventual co-opting by Maxwell Lord is one of the main events that leads o the Infinite Crisis miniseries, which again restructures DC continuity.
A young Bruce Wayne can also be seen in his bedroom praying, strongly hinting him to be a Christian just like his Mother. Pearson and Uricchio also noted beyond the origin story and such events as the introduction of Robin, "Until recently, the fixed and occurring and hence, canonized, events have been few in number," a situation altered by an increased effort by later Batman editors such as Dennis O'Neil to ensure consistency and continuity between stories.
