Batman is often treated as a vigilante by other characters in his stories. Frank Miller views the character as "a dionysian figure, a force for anarchy that imposes an individual order". Dressed as a bat, Batman deliberately cultivates a frightening persona in order to aid him in crime-fighting, a fear that originates from the criminals' own guilty conscience. Miller is often credited with reintroducing anti-heroic traits into Batman's characterization, such as his brooding personality, willingness to use violence and torture, and increasingly alienated behavior. Batman, shortly a year after his debut and the introduction of Robin, was changed in 1940 after DC editor Whitney Ellsworth felt the character would be tainted by his lethal methods and DC established their own ethical code, subsequently he was retconned as having a stringent moral code. Miller's Batman was closer to the original pre-Robin version, who was willing to kill criminals if necessary.
Batman's secret identity is Bruce Wayne, a wealthy American industrialist. As a child, Bruce witnessed the murder of his parents, Dr. Thomas Wayne and Martha Wayne, which ultimately led him to craft the Batman persona and seek justice against criminals. He resides on the outskirts of Gotham City in his personal residence, Wayne Manor. Wayne averts suspicion by acting the part of a superficial playboy idly living off his family's fortune and the profits of Wayne Enterprises, his inherited conglomerate. He supports philanthropic causes through his nonprofit Wayne Foundation, but is more widely known as a celebrity socialite. In public, he frequently appears in the company of high-status women, which encourages tabloid gossip. Although Bruce Wayne leads an active romantic life, his vigilante activities as Batman account for most of his time.
Although Kane initially rebutted Finger's claims at having created the character, writing in a 1965 open letter to fans that "it seemed to me that Bill Finger has given out the impression that he and not myself created the ''Batman, t' [sic] as well as Robin and all the other leading villains and characters. This statement is fraudulent and entirely untrue." Kane himself also commented on Finger's lack of credit. "The trouble with being a 'ghost' writer or artist is that you must remain rather anonymously without 'credit'. However, if one wants the 'credit', then one has to cease being a 'ghost' or follower and become a leader or innovator."
While very similar to the original version shown in Batman, the Batman Returns bat suit shows us an updated version which shows obvious armor on the chest and full torso area. This suit was used against characters like Danny DeVito’s Penguin and Michelle Pfeiffer’s Catwoman during a storyline where Penguin was running to become the mayor of Gotham City and Selena Kyle was a lowly secretary who was just trying to do right by her boss… up until he murders her and she gets cat powers.
Starting in 1969, writer Dennis O'Neil and artist Neal Adams made a deliberate effort to distance Batman from the campy portrayal of the 1960s TV series and to return the character to his roots as a "grim avenger of the night". O'Neil said his idea was "simply to take it back to where it started. I went to the DC library and read some of the early stories. I tried to get a sense of what Kane and Finger were after."
Attaching a protective mask, Batman creates a propulsion tunnel to blast through the vat. The propulsion blast allows Batman to escape, but the corrosion heavily damages his suit. Returning home, Batman sends a message to his allies to warn them that the Joker might be targeting them individually. At the manor, Bruce finds a cassette tape, in which the Joker reveals he has kidnapped Alfred. Batman later visits Gordon, who was designated as Joker's next victim. Gordon begins to bleed uncontrollably, so Batman sends him to the hospital. Knowing that the Joker is re-enacting his previous crimes, Batman goes to the Gotham Reservoir, the first place he faced the Joker in his current identity. There, the Joker traps Batman with cables, immobilizing. The Joker says that Batman's care for his allies has made him weak, so he plans to kill them all in the next 72 hours.
In those days it was like, one artist and he had his name over it [the comic strip] — the policy of DC in the comic books was, if you can't write it, obtain other writers, but their names would never appear on the comic book in the finished version. So Bill never asked me for it [the byline] and I never volunteered — I guess my ego at that time. And I felt badly, really, when he [Finger] died.
