Batman is a superhero who appears in American comic books published by DC Comics. Batman was created by the artist Bob Kane and writer Bill Finger, and debuted in the 27th issue of the comic book Detective Comics on March 30, 1939. In the DC Universe, Batman is the alias of Bruce Wayne, a wealthy American playboy, philanthropist, and industrialist who resides in Gotham City. His origin story features him swearing vengeance against criminals after witnessing the murder of his parents, Thomas and Martha, as a child, a vendetta tempered by the ideal of justice. He trains himself physically and intellectually, crafts a bat-inspired persona, and monitors the Gotham streets at night. Kane, Finger, and other creators accompanied Batman with supporting characters, including his sidekicks Robin and Batgirl; allies Alfred Pennyworth and James Gordon; love interest Catwoman; and foes such as the Penguin, the Riddler, Two-Face, and his archenemy, the Joker.

Kane conceived Batman in early 1939 to capitalize on the popularity of Superman; although Kane frequently claimed sole creation credit, Finger substantially developed the concept from a generic superhero into something more bat-like. They drew inspiration from pulp fiction characters like the Shadow and Sherlock Holmes. Batman received a spin-off publication, Batman, in 1940. Kane and Finger introduced Batman as a ruthless vigilante who frequently killed or maimed criminals, but he evolved into a just, tempered superhero with a stringent moral code that prohibits killing during the 1940s. Unlike most superheroes, Batman does not possess any superpowers, instead relying on his intellect, fighting skills, and wealth. The 1960s Batman television series used a camp aesthetic, which continued to be associated with Batman for years after it ended. Various creators worked to return Batman to his darker roots in the 1970s and 1980s, culminating with the 1986 miniseries The Dark Knight Returns by Frank Miller.

DC has featured Batman in many comic books, including comics published under its imprints such as Vertigo and Black Label; he has been considered DC's flagship character since the 1990s. The longest-running Batman comic, Detective Comics, is the longest-running comic book in the United States. Batman is frequently depicted alongside other DC superheroes, such as Superman and Wonder Woman, as a member of organizations such as the Justice League and the Outsiders. In addition to Bruce Wayne, other characters used the Batman persona, such as Jean-Paul Valley / Azrael in the 1993–1994 "Knightfall" story arc; Dick Grayson, the first Robin, from 2009 to 2011; and Jace Fox, the son of Wayne's ally Lucius, since 2021. DC has also published comics featuring alternate versions of Batman, including the incarnation seen in The Dark Knight Returns and its successors, the incarnation from the Flashpoint (2011) event, and numerous interpretations in comics published under the Elseworlds label.

Batman is one of the most iconic characters in popular culture and has been listed among the greatest comic book superheroes and characters ever created. He is one of the most commercially successful superheroes, and his likeness has been licensed and featured in various media and merchandise sold around the world; this includes toy lines such as Lego Batman and video games such as the Batman: Arkham series. Batman has been adapted in many live-action and animated television series and films. Adam West portrayed him in the 1960s Batman television series, and he has been portrayed in film by Michael Keaton, Val Kilmer, George Clooney, Christian Bale, Ben Affleck, and Robert Pattinson. Many actors, most prolifically Kevin Conroy, have provided Batman's voice in animation and video games. In September 2024, Batman was given the first star to a superhero on the Hollywood Walk of Fame.

In early 1939, following the success of Superman, DC Comics' editors requested more superheroes. Bob Kane created Batman, initially drawing a character with red tights, bat wings, and a domino mask. Bill Finger, a collaborator, made significant contributions by suggesting a cowl, cape, gloves, and a darker costume. The character's alter ego, Bruce Wayne, was inspired by historical figures Robert the Bruce and Mad Anthony Wayne. Batman's early adventures drew inspiration from contemporary pulp fiction and characters like Zorro and the Shadow, establishing Batman as a master detective with a dark, brooding persona driven by the murder of his parents.

Batman debuted in Detective Comics #27 in 1939. Early stories were dark, featuring a Batman who did not shy away from killing. The character quickly became popular, leading to his own solo title in 1940. Robin, Batman's sidekick, was introduced in 1940, lightening the tone and boosting sales. Over the next few years, Batman's rogues' gallery expanded with iconic villains like the Joker and Catwoman. The 1950s saw Batman in lighter, science fiction-influenced stories. However, declining sales led to a 1964 revamp by editor Julius Schwartz, who returned Batman to his detective roots and updated his appearance. The 1966 Batman TV series introduced a campy, humorous tone, which was reflected in the comics until its cancellation in 1968. In the 1970s, writers Dennis O'Neil and Neal Adams restored Batman's dark, gritty nature, a trend that continued despite fluctuating sales.

In the Modern Age of Comic Books Batman comics have undergone significant transformations, reflecting changing storytelling trends and audience interests. Beginning with seminal works like The Dark Knight Returns in the 1980s, which reintroduced Batman in a grittier, more mature context, the character's narrative evolved to explore deeper themes and darker tones. This period also saw the exploration of Batman's origins and psyche through works like Batman: Year One, and Batman: The Killing Joke, which delved into the complexities of heroism and villainy. In the 1990s, storylines such as "Knightfall" introduced new adversaries like Bane, who physically and mentally challenged Batman, leading to a temporary replacement by Jean-Paul Valley. The aftermath of an earthquake in "No Man's Land" depicted Gotham City in chaos, further pushing Batman to new limits of heroism and survival. Entering the 21st century, Grant Morrison's influential run introduced Damian Wayne as Batman's son and heir, bringing familial dynamics and a new generation of challenges to the forefront. Morrison's storytelling also delved into surreal and existential themes, such as in Batman R.I.P. and Final Crisis, which tested Batman's resolve and sanity against cosmic threats and personal demons. The New 52 reboot in 2011 refreshed Batman's continuity while preserving core elements of his character. This era introduced modern interpretations of classic storylines, like Night of the Owls, where Batman confronts the Court of Owls, a clandestine society controlling Gotham for centuries. The chilling return of the Joker in "Death of the Family" explored the intricate relationships within Batman's extended family of allies and adversaries. More recent developments under DC Rebirth and Infinite Frontier have continued to evolve Batman's universe, exploring new characters like Gotham and Gotham Girl, and tackling contemporary issues within the context of Gotham City's ever-evolving landscape of crime and heroism.

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, which in part addresses social issues encouraging crime as well as assisting victims of it, 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 while feigning near-drunkenness with consuming large quantities of disguised ginger ale since Wayne is actually a strict teetotaler to maintain his physical and mental prowess. Although Bruce Wayne leads an active romantic life, his vigilante activities as Batman account for most of his time.

Various modern stories have portrayed the extravagant, playboy image of Bruce Wayne as a facade. This is in contrast to the Post-Crisis Superman, whose Clark Kent persona is the true identity, while the Superman persona is the facade. In Batman Unmasked, a television documentary about the psychology of the character, behavioral scientist Benjamin Karney notes that Batman's personality is driven by Bruce Wayne's inherent humanity; that "Batman, for all its benefits and for all of the time Bruce Wayne devotes to it, is ultimately a tool for Bruce Wayne's efforts to make the world better". Bruce Wayne's principles include the desire to prevent future harm and a vow not to kill. Bruce Wayne believes that our actions define us, we fail for a reason, and anything is possible.

Writers of Batman and Superman stories have often compared and contrasted the two. Interpretations vary depending on the writer, the story, and the timing. Grant Morrison notes that both heroes "believe in the same kind of things" despite the day/night contrast their heroic roles display. Morrison notes an equally stark contrast in their real identities. Bruce Wayne and Clark Kent belong to different social classes: "Bruce has a butler, Clark has a boss." T. James Musler's book Unleashing the Superhero in Us All explores the extent to which Bruce Wayne's vast personal wealth is important in his life story, and the crucial role it plays in his efforts as Batman.

Will Brooker notes in his book Batman Unmasked that "the confirmation of the Batman's identity lies with the young audience ...he doesn't have to be Bruce Wayne; he just needs the suit and gadgets, the abilities, and most importantly the morality, the humanity. There's just a sense about him: 'they trust him ...and they're never wrong."

Batman's primary character traits can be summarized as "wealth; physical prowess; deductive abilities and obsession". The details and tone of Batman comic books have varied over the years with different creative teams. Dennis O'Neil noted that character consistency was not a major concern during early editorial regimes: "Julie Schwartz did a Batman in Batman and Detective and Murray Boltinoff did a Batman in the Brave and the Bold and apart from the costume they bore very little resemblance to each other. Julie and Murray did not want to coordinate their efforts, nor were they asked to do so. Continuity was not important in those days."

The driving force behind Bruce Wayne's character is his parents' murder and their absence. Bob Kane and Bill Finger discussed Batman's background and decided that "there's nothing more traumatic than having your parents murdered before your eyes". Despite his trauma, he sets his mind on studying to become a scientist and to train his body into physical perfection to fight crime in Gotham City as Batman, an inspired idea from Wayne's insight into the criminal mind. He also speaks over 40 languages.

Another of Batman's characterizations is that of a vigilante; in order to stop evil that started with the death of his parents, he must sometimes break the law himself. Although manifested differently by being re-told by different artists, it is nevertheless that the details and the prime components of Batman's origin have never varied at all in the comic books, the "reiteration of the basic origin events holds together otherwise divergent expressions". The origin is the source of the character's traits and attributes, which play out in many of the character's adventures.

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 to have a stringent moral code, which has stayed with the character of Batman ever since. Miller's Batman was closer to the original pre-Robin version, who was willing to kill criminals if necessary.

On several occasions former Robin Dick Grayson has served as Batman; most notably in 2009 while Wayne was believed dead, and served as a second Batman even after Wayne returned in 2010. As part of DC's 2011 continuity relaunch, Grayson returned to being Nightwing following the Flashpoint crossover event.

In an interview with IGN, Morrison detailed that having Dick Grayson as Batman and Damian Wayne as Robin represented a "reverse" of the normal dynamic between Batman and Robin, with, "a more light-hearted and spontaneous Batman and a scowling, badass Robin". Morrison explained their intentions for the new characterization of Batman: "Dick Grayson is kind of this consummate superhero. The guy has been Batman's partner since he was a kid, he's led the Teen Titans, and he's trained with everybody in the DC Universe. So he's a very different kind of Batman. He's a lot easier; He's a lot looser and more relaxed."

Over the years, there have been numerous others to assume the name of Batman, or to officially take over for Bruce during his leaves of absence. Jean-Paul Valley, also known as Azrael, assumed the cowl after the events of the Knightfall saga. Jim Gordon donned a mecha-suit after the events of Batman: Endgame, and served as Batman in 2015 and 2016. In 2021, as part of the Fear State crossover event, Lucius Fox's son Jace Fox succeeds Bruce as Batman in a 2021 storyline, depicted in the series I Am Batman, after Batman was declared dead.

Additionally, members of the group Batman Incorporated, Bruce Wayne's experiment at franchising his brand of vigilantism, have at times stood in as the official Batman in cities around the world. Various others have also taken up the role of Batman in stories set in alternative universes and possible futures, including, among them, various former proteges of Bruce Wayne.

Batman's interactions with both villains and cohorts have, over time, developed a strong supporting cast of characters.

Batman faces a variety of foes ranging from common criminals to outlandish supervillains. Many of them mirror aspects of the Batman's character and development, often having tragic origin stories that lead them to a life of crime. These foes are commonly referred to as Batman's rogues gallery. Batman's "most implacable foe" is the Joker, a homicidal maniac with a clown-like appearance. The Joker is considered by critics to be his perfect adversary, since he is the antithesis of Batman in personality and appearance; the Joker has a maniacal demeanor with a colorful appearance, while Batman has a serious and resolute demeanor with a dark appearance. As a "personification of the irrational", the Joker represents "everything Batman [opposes]". Other long-time recurring foes that are part of Batman's rogues gallery include Catwoman (a cat burglar anti-heroine who is variously an ally and romantic interest), the Penguin, Ra's al Ghul, Two-Face (Harvey Dent), the Riddler, the Scarecrow, Mr. Freeze, Poison Ivy, Harley Quinn, Bane, Clayface, and Killer Croc, among others. Many of Batman's adversaries are often psychiatric patients at Arkham Asylum.

Alfred Pennyworth, Batman's loyal butler and father figure, first appeared in Batman #16 (1943). After Bruce Wayne's parents were killed, Alfred raised Bruce and became one of the few people to know his secret identity. He is often portrayed as a steadying presence in Bruce's life, offering both emotional support and practical assistance in Batman's crime-fighting endeavors. More than just a caretaker, Alfred is a trusted ally and sometimes sidekick, sharing Wayne Manor with Bruce and contributing to Batman's mission.

One of Batman's most crucial allies is Commissioner James Gordon. Their relationship is built on mutual respect and a shared commitment to justice in Gotham City. In Batman: Year One, Gordon and Batman learn to trust each other, which transforms their efforts against crime into a more effective partnership. Gordon's perspective as a police officer complements Batman's vigilantism, allowing them to tackle Gotham's challenges together. Another important ally is the Justice League, which further emphasizes the importance of collaboration. Batman's relationship with Superman showcases how their contrasting ideologies can complement each other. In stories like World's Finest, their friendship highlights how Batman's methods benefit from Superman's optimism and strength.

Robin, Batman's vigilante partner, has been a widely recognized supporting character for many years; each iteration of the Robin character, of which there have been five in the mainstream continuity, function as members of the Batman family, but additionally, as Batman's "central" sidekick in various media. Bill Finger stated that he wanted to include Robin because "Batman didn't have anyone to talk to, and it got a little tiresome always having him thinking." The first Robin, Dick Grayson, was introduced in 1940. In the 1970s he finally grew up, went off to college and became the hero Nightwing. A second Robin, Jason Todd was introduced in the 1980s, following Dick Grayson's departure from the role. Initially impulsive and rebellious, Jason's tenure as Robin was controversial among fans. In 1988, DC held a fan vote to determine his fate in the iconic A Death in the Family storyline, where the Joker brutally beat Jason with a crowbar and left him to die in an explosion. The fans voted for his death. However, Jason was later resurrected and returned as the antihero Red Hood.

The third Robin in the mainstream comics is Tim Drake, who first appeared in 1989. He went on to star in his own comic series, and goes by the name Red Robin, a variation on the traditional Robin persona. In the first decade of the new millennium, Stephanie Brown served as the fourth in-universe Robin between stints as her self-made vigilante identity the Spoiler, and later as Batgirl. After Brown's apparent death, Drake resumed the role of Robin for a time. The role eventually passed to Damian Wayne, the 10-year-old son of Bruce Wayne and Talia al Ghul, in the late 2000s. Damian's tenure as du jour Robin ended when the character was killed off in the pages of Batman Incorporated in 2013. Batman's next young sidekick is Harper Row, a streetwise young woman who avoids the name Robin but followed the ornithological theme nonetheless; she debuted the codename and identity of the Bluebird in 2014. Unlike the Robins, the Bluebird is willing and permitted to use a gun, albeit non-lethal; her weapon of choice is a modified rifle that fires taser rounds. In 2015, a new series began titled We Are...Robin, focused on a group of teenagers using the Robin persona to fight crime in Gotham City. The most prominent of these, Duke Thomas, later becomes Batman's crimefighting partner as The Signal.

Batman's romantic history spans decades, filled with relationships that reflect his struggle between personal happiness and his duty as Gotham's protector. His first love interest was Julie Madison, introduced in Detective Comics #31 (1939). Though engaged to Bruce Wayne, she left due to his distant and playboy persona, highlighting the conflict between Bruce's dual life and his desire for a normal relationship.

Selina Kyle, also known as Catwoman, is perhaps the most notable figure in Batman's romantic history. Debuting in Batman #1 (1940), their relationship is characterized by a blend of romance and rivalry. Over the years, they have shared intense connections, often navigating the fine line between love and conflict. Their relationship culminated in an engagement during the Rebirth era.

Another important figure is Vicki Vale, a journalist introduced in Batman #49 (1948). Vicki's attempts to uncover Batman's true identity lead to a complicated romantic involvement that waxed and waned over the years, especially during the early 1980s when their relationship became more serious.

Talia al Ghul, introduced in Detective Comics #411 (1971), is another key player in Batman's love life. Their relationship is fraught with conflict due to her father, Ra's al Ghul, and his criminal ambitions. Despite the challenges, their love story resulted in the birth of Damian Wayne, who would grow to become the latest Robin and add a new layer of complexity to Batman's character.

Additionally, Batman's relationship with Wonder Woman has been explored in various storylines, including a passionate kiss in JLA (2003) during a moment of crisis. However, their relationship remains largely unexplored, often overshadowed by their respective commitments.

One of the most controversial romantic pairings emerged from the animated adaptation of Batman: The Killing Joke (2016), which depicted a brief romantic involvement between Batman and Batgirl (Barbara Gordon). This portrayal sparked significant criticism among fans, reflecting the challenges and complexities of Batman's romantic entanglements over the years.

Batman has no inherent superhuman powers; he relies on "his own scientific knowledge, detective skills, and athletic prowess". Batman's inexhaustible wealth gives him access to advanced technologies, and as a proficient scientist, he is able to use and modify these technologies to his advantage. In the stories, Batman is regarded as one of the world's greatest detectives, if not the world's greatest crime solver. Batman has been repeatedly described as having a genius-level intellect, being one of the greatest martial artists in the DC Universe, and having peak human physical and mental conditioning. As a polymath, his knowledge and expertise in countless disciplines is nearly unparalleled by any other character in the DC Universe. He has shown prowess in assorted fields such as mathematics, biology, physics, chemistry, and several levels of engineering. He has traveled the world acquiring the skills needed to aid him in his endeavors as Batman. In the Superman: Doomed story arc, Superman considers Batman to be one of the most brilliant minds on the planet.

Batman has trained extensively in various fighting styles, making him one of the best hand-to-hand fighters in the DC Universe. He possesses a photographic memory, and has fully utilized his photographic memory to master a total of 127 forms of martial arts. In terms of his physical condition, Batman is described as peak human and far beyond an Olympic-athlete-level condition, able to perform feats such as easily running across rooftops in a Parkour-esque fashion, pressing thousands of pounds regularly, and even bench pressing six hundred pounds of soil and coffin in a poisoned and starved state. Superman describes Batman as "the most dangerous man on Earth", able to defeat an entire team of superpowered extraterrestrials by himself in order to rescue his imprisoned teammates in Grant Morrison's first storyline in JLA.

Batman is strongly disciplined, and he has the ability to function under great physical pain and resist most forms of telepathy and mind control. He is a master of disguise, multilingual, and an expert in espionage, often gathering information under the identity of a notorious gangster named Matches Malone. Batman is highly skilled in stealth movement and escapology, which allows him to appear and disappear at will and to break free of nearly inescapable deathtraps with little to no harm. He is also a master strategist, considered DC's greatest tactician, with numerous plans in preparation for almost any eventuality.

Batman is an expert in interrogation techniques and his intimidating and frightening appearance alone is often all that is needed in getting information from suspects. Despite having the potential to harm his enemies, Batman's most defining characteristic is his strong commitment to justice and his reluctance to take a life. This unyielding moral rectitude has earned him the respect of several heroes in the DC Universe, most notably that of Superman and Wonder Woman.

Among physical and other crime fighting related training, he is also proficient at other types of skills. Some of these include being a licensed pilot (in order to operate the Batplane), as well as being able to operate other types of machinery. In some publications, he even underwent some magician training.

Batman utilizes a vast arsenal of specialized, high-tech vehicles and gadgets in his war against crime, the designs of which usually share a bat motif. Batman historian Les Daniels credits Gardner Fox with creating the concept of Batman's arsenal with the introduction of the utility belt in Detective Comics #29 (July 1939) and the first bat-themed weapons the batarang and the "Batgyro" in Detective Comics #31 and 32 (Sept. and October 1939).

Personal armor

Batman's batsuit aids in his combat against enemies, having the properties of both Kevlar and Nomex. It protects him from gunfire and other significant impacts, and incorporates the imagery of a bat in order to frighten criminals.

The details of the Batman costume change repeatedly through various decades, stories, media and artists' interpretations, but the most distinctive elements remain consistent: a scallop-hem cape; a cowl covering most of the face; a pair of bat-like ears; a stylized bat emblem on the chest; and the ever-present utility belt. His gloves typically feature three scallops that protrude from long, gauntlet-like cuffs, although in his earliest appearances he wore short, plain gloves without the scallops. The overall look of the character, particularly the length of the cowl's ears and of the cape, varies greatly depending on the artist. Dennis O'Neil said, "We now say that Batman has two hundred suits hanging in the Batcave so they don't have to look the same ...Everybody loves to draw Batman, and everybody wants to put their own spin on it."

Finger and Kane originally conceptualized Batman as having a black cape and cowl and grey suit, but conventions in coloring called for black to be highlighted with blue. Hence, the costume's colors have appeared in the comics as dark blue and grey; as well as black and grey. In the Tim Burton's Batman and Batman Returns films, Batman has been depicted as completely black with a bat in the middle surrounded by a yellow background. Christopher Nolan's The Dark Knight Trilogy depicted Batman wearing high-tech gear painted completely black with a black bat in the middle. Ben Affleck's Batman in the DC Extended Universe films wears a suit grey in color with a black cowl, cape, and bat symbol. Seemingly following the suit of the DC Extended Universe outfit, Robert Pattinson's uniform in The Batman restores the more traditional gray bodysuit and black appendage design, notably different from prior iterations by mostly utilizing real world armor and apparel pieces from modern military and motorcycle gear.

Batmobile

Batman's primary vehicle is the Batmobile, which is usually depicted as an imposing black car, often with tailfins that suggest a bat's wings.

Batman also has an aircraft called the Batplane (originally a relatively traditionally, but bat-motifed plane, later seen as the much more unique "Batwing" starting in the 1989 film), along with various other means of transportation.

In proper practice, the "bat" prefix (as in Batmobile or batarang) is rarely used by Batman himself when referring to his equipment, particularly after some portrayals (primarily the 1960s Batman live-action television show and the Super Friends animated series) stretched the practice to campy proportions. For example, the 1960s television show depicted a Batboat, Bat-Sub, and Batcycle, among other bat-themed vehicles. The 1960s television series Batman has an arsenal that includes such "bat-" names as the Bat-computer, Bat-scanner, bat-radar, bat-cuffs, bat-pontoons, bat-drinking water dispenser, bat-camera with polarized bat-filter, bat-shark repellent bat-spray, and Bat-rope. The storyline "A Death in the Family" suggests that given Batman's grim nature, he is unlikely to have adopted the "bat" prefix on his own. In The Dark Knight Returns, Batman tells Carrie Kelley that the original Robin came up with the name "Batmobile" when he was young, since that is what a kid would call Batman's vehicle.

The Batmobile, which was before frequently depicted to resemble a sports car, was redesigned in 2011 when DC Comics relaunched its entire line of comic books, with the Batmobile being given heavier armor and new aesthetics.

Utility belt

Batman keeps most of his field equipment in his utility belt. Over the years it has shown to contain an assortment of crime-fighting tools, weapons, and investigative and technological instruments. Different versions of the belt have these items stored in compartments, often as pouches or hard cylinders attached evenly around it.

Since the 1989 film, Batman is often depicted as carrying a projectile which shoots a retractable grappling hook attached to a cable (before this, a he employed a traditionally thrown grappling hook.) This allows him to attach to distant objects, be propelled into the air, and thus swing from the rooftops of Gotham City.

An exception to the range of Batman's equipment are hand guns, which he refuses to use on principle, since a gun was used in his parents' murder. In modern stories in terms of his vehicles, Batman compromises on that principle to install weapon systems on them for the purpose of non-lethally disabling other vehicles, forcing entry into locations and attacking dangerous targets too large to defeat by other means.

Bat-Signal

When Batman is needed, the Gotham City police activate a searchlight with a bat-shaped insignia over the lens called the Bat-Signal, which shines into the night sky, creating a bat-symbol on a passing cloud which can be seen from any point in Gotham. The origin of the signal varies, depending on the continuity and medium.

In various incarnations, most notably the 1960s Batman TV series, Commissioner Gordon also has a dedicated phone line, dubbed the Bat-Phone, connected to a bright red telephone (in the TV series) which sits on a wooden base and has a transparent top. The line connects directly to Batman's residence, Wayne Manor, specifically both to a similar phone sitting on the desk in Bruce Wayne's study and the extension phone in the Batcave.

Batcave

The Batcave is Batman's secret headquarters, consisting of a series of caves beneath his mansion, Wayne Manor. As his command center, the Batcave serves multiple purposes; supercomputer, surveillance, redundant power-generators, forensics lab, medical infirmary, private study, training dojo, fabrication workshop, arsenal, hangar and garage. It houses the vehicles and equipment Batman uses in his campaign to fight crime. It is also a trophy room and storage facility for Batman's unique memorabilia collected over the years from various cases he has worked on.

In both the comic book Batman: Shadow of the Bat #45 and the 2005 film Batman Begins, the cave is said to have been part of the Underground Railroad.

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."

The central fixed event in the Batman stories is the character's origin story. As a young boy, Bruce Wayne was horrified and traumatized when he watched his parents, the physician Dr. Thomas Wayne and his wife Martha, murdered with a gun by a mugger named Joe Chill. Batman refuses to utilize any sort of gun on the principle that a gun was used to murder his parents. This event drove him to train his body to its peak condition and fight crime in Gotham City as Batman. Pearson and Uricchio also noted beyond the origin story and such events as the introduction of Robin, "Until recently, the fixed and accruing 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.

In Batman's first appearance in Detective Comics #27, he is already operating as a crime-fighter. Batman's origin is first presented in Detective Comics #33 (November 1939) and is later expanded upon in Batman #47. As these comics state, Bruce Wayne is born to Dr. Thomas Wayne and his wife Martha, two very wealthy and charitable Gotham City socialites. Bruce is brought up in Wayne Manor, and leads a happy and privileged existence until the age of 8, when his parents are killed by a small-time criminal named Joe Chill while on their way home from a movie theater. That night, Bruce Wayne swears an oath to spend his life fighting crime. He engages in intense intellectual and physical training; however, he realizes that these skills alone would not be enough. "Criminals are a superstitious cowardly lot", Wayne remarks, "so my disguise must be able to strike terror into their hearts. I must be a creature of the night, black, terrible ..." As if responding to his desires, a bat suddenly flies through the window, inspiring Bruce to craft the Batman persona.

In early strips, Batman's career as a vigilante earns him the ire of the police. During this period, Bruce Wayne has a fiancé named Julie Madison. In Detective Comics #38, Wayne takes in an orphaned circus acrobat, Dick Grayson, who becomes his vigilante partner, Robin. Batman also becomes a founding member of the Justice Society of America, although he, like Superman, is an honorary member, and thus only participates occasionally. Batman's relationship with the law thaws quickly, and he is made an honorary member of Gotham City's police department. During this time, Alfred Pennyworth arrives at Wayne Manor, and after deducing the Dynamic Duo's secret identities, joins their service as their butler.

The Silver Age of Comic Books in DC Comics is sometimes held to have begun in 1956 when the publisher introduced Barry Allen as a new, updated version of the Flash. Batman is not significantly changed by the late 1950s for the continuity which would be later referred to as Earth-One. The lighter tone Batman had taken in the period between the Golden and Silver Ages led to the stories of the late 1950s and early 1960s that often feature many science-fiction elements, and Batman is not significantly updated in the manner of other characters until Detective Comics #327 (May 1964), in which Batman reverts to his detective roots, with most science-fiction elements jettisoned from the series.

After the introduction of DC Comics' Multiverse in the 1960s, DC established that stories from the Golden Age star the Earth-Two Batman, a character from a parallel world. This version of Batman partners with and marries the reformed Earth-Two Catwoman (Selina Kyle). The two have a daughter, Helena Wayne, who becomes the Huntress. She assumes the position as Gotham's protector along with Dick Grayson, the Earth-Two Robin, once Bruce Wayne retires to become police commissioner. Wayne holds the position of police commissioner until he is killed during one final adventure as Batman. Batman titles, however, often ignored that a distinction had been made between the pre-revamp and post-revamp Batmen (since unlike the Flash or Green Lantern, Batman comics had been published without interruption through the 1950s) and would occasionally make reference to stories from the Golden Age. Nevertheless, details of Batman's history were altered or expanded upon through the decades. Additions include meetings with a future Superman during his youth, his upbringing by his uncle Philip Wayne (introduced in Batman #208 (February 1969)) after his parents' death, and appearances of his father and himself as prototypical versions of Batman and Robin, respectively. In 1980, then-editor Paul Levitz commissioned the Untold Legend of the Batman miniseries to thoroughly chronicle Batman's origin and history.

Batman meets and regularly works with other heroes during the Silver Age, most notably Superman, whom he began regularly working alongside in a series of team-ups in World's Finest Comics, starting in 1954 and continuing through the series' cancellation in 1986. Batman and Superman are usually depicted as close friends. As a founding member of the Justice League of America, Batman appears in its first story, in 1960's The Brave and the Bold #28. In the 1970s and 1980s, The Brave and the Bold became a Batman title, in which Batman teams up with a different DC Universe superhero each month.

In 1969, Dick Grayson attends college as part of DC Comics' effort to revise the Batman comics. Additionally, Batman also moves from his mansion, 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. In 1974's "Night of the Stalker" storyline, a diploma on the wall reveals Bruce Wayne as a graduate of Yale Law School. 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 the Joker as a homicidal psychopath, and the arrival of Ra's al Ghul, a centuries-old terrorist who knows Batman's secret identity. In the 1980s, Dick Grayson becomes Nightwing.

In the final issue of The Brave and the Bold in 1983, Batman quits the Justice League and forms a new group called the Outsiders. He serves as the team's leader until Batman and the Outsiders #32 (1986) and the comic subsequently changed its title.

After the 12-issue miniseries Crisis on Infinite Earths, DC Comics retconned the histories of some major characters in an attempt at updating them for contemporary audiences. Frank Miller retold Batman's origin in the storyline "Year One" from Batman #404–407, which emphasizes a grittier tone in the character. Though the Earth-Two Batman is erased from history, many stories of Batman's Silver Age/Earth-One career (along with an amount of Golden Age ones) remain canonical in the Post-Crisis universe, with his origins remaining the same in essence, despite alteration. For example, Gotham's police are mostly corrupt, setting up further need for Batman's existence. The guardian Phillip Wayne is removed, leaving young Bruce to be raised by Alfred Pennyworth. Additionally, Batman is no longer a founding member of the Justice League of America, although he becomes leader for a short time of a new incarnation of the team launched in 1987. To help fill in the revised backstory for Batman following Crisis, DC launched a new Batman title called Legends of the Dark Knight in 1989 and has published various miniseries and one-shot stories since then that largely take place during the "Year One" period.

Subsequently, Batman begins exhibiting an excessive, reckless approach to his crimefighting, a result of the pain of losing Jason Todd. Batman works solo until the decade's close, when Tim Drake becomes the new Robin.

Many of the major Batman storylines since the 1990s have been intertitle crossovers that run for a number of issues. In 1993, DC published "Knightfall". During the storyline's first phase, the new villain Bane paralyzes Batman, leading Wayne to ask Azrael to take on the role. After the end of "Knightfall", the storylines split in two directions, following both the Azrael-Batman's adventures, and Bruce Wayne's quest to become Batman once more. The story arcs realign in "KnightsEnd", as Azrael becomes increasingly violent and is defeated by a healed Bruce Wayne. Wayne hands the Batman mantle to Dick Grayson (then Nightwing) for an interim period, while Wayne trains for a return to the role.

The 1994 company-wide crossover storyline Zero Hour: Crisis in Time! changes aspects of DC continuity again, including those of Batman. Noteworthy among these changes is that the general populace and the criminal element now consider Batman an urban legend rather than a known force.

Batman once again becomes a member of the Justice League during Grant Morrison's 1996 relaunch of the series, titled JLA. During this time, Gotham City faces catastrophe in the decade's closing crossover arc. In 1998's "Cataclysm" storyline, Gotham City is devastated by an earthquake and ultimately cut off from the United States. Deprived of many of his technological resources, Batman fights to reclaim the city from legions of gangs during 1999's "No Man's Land".

Meanwhile, Batman's relationship with the Gotham City Police Department changed for the worse with the events of "Batman: Officer Down" and "Batman: War Games/War Crimes"; Batman's long-time law enforcement allies Commissioner Gordon and Harvey Bullock are forced out of the police department in "Officer Down", while "War Games" and "War Crimes" saw Batman become a wanted fugitive after a contingency plan of his to neutralize Gotham City's criminal underworld is accidentally triggered, resulting in a massive gang war that ends with the sadistic Black Mask the undisputed ruler of the city's criminal gangs. Lex Luthor arranges for the murder of Batman's on-again, off-again love interest Vesper Lynd (introduced in the mid-1990s) during the "Bruce Wayne: Murderer?" and "Bruce Wayne: Fugitive" story arcs. Though Batman is able to clear his name, he loses another ally in the form of his new bodyguard Sasha, who is recruited into the organization known as "Checkmate" while stuck in prison due to her refusal to turn state's evidence against her employer. While he was unable to prove that Luthor was behind the murder of Vesper, Batman does get his revenge with help from Talia al Ghul in Superman/Batman #1–6.

DC Comics' 2005 miniseries Identity Crisis reveals that JLA member Zatanna had edited Batman's memories to prevent him from stopping the Justice League from lobotomizing Dr. Light after he raped Sue Dibny. Batman later creates the Brother I satellite surveillance system to watch over and, if necessary, kill the other heroes after he remembered. The revelation of Batman's creation and his tacit responsibility for the Blue Beetle's death becomes a driving force in the lead-up to the Infinite Crisis miniseries, which again restructures DC continuity. Batman and a team of superheroes destroy Brother EYE and the OMACs, though, at the very end, Batman reaches his apparent breaking point when Alexander Luthor Jr. seriously wounds Nightwing. Picking up a gun, Batman nearly shoots Luthor in order to avenge his former sidekick, until Wonder Woman convinces him to not pull the trigger.

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 Batman: Son of the Demon, Bruce's coupling with Talia was implied to be consensual, this arc retconned it into Talia forcing herself on Bruce.

Batman, along with Superman and Wonder Woman, reforms the Justice League in the new Justice League of America series, and is leading the newest incarnation of the Outsiders.

Grant Morrison's 2008 storyline, "Batman R.I.P." featured Batman being physically and mentally broken by the enigmatic villain Doctor Hurt and attracted news coverage in advance of its highly promoted conclusion, which would speculated to feature the death of Bruce Wayne. However, though Batman is shown to possibly perish at the end of the arc, the two-issue arc "Last Rites", which leads into the crossover storyline "Final Crisis", shows that Batman survives his helicopter crash into the Gotham City River and returns to the Batcave, only to be summoned to the Hall of Justice by the JLA to help investigate the New God Orion's death. The story ends with Batman retrieving the god-killing bullet used to kill Orion, setting up its use in "Final Crisis". In the pages of Final Crisis Batman is reduced to a charred skeleton. In Final Crisis #7, Wayne is shown witnessing the passing of the first man, Anthro. Wayne's "death" sets up the three-issue Battle for the Cowl miniseries in which Wayne's ex-proteges compete for the "right" to assume the role of Batman, which concludes with Grayson becoming Batman, while Tim Drake takes on the identity of the Red Robin. Dick and Damian continue as Batman and Robin, and in the crossover storyline "Blackest Night", what appears to be Bruce's corpse is reanimated as a Black Lantern zombie, but is later shown that Bruce's corpse is one of Darkseid's failed Batman clones. Dick and Batman's other friends conclude that Bruce is alive.

Bruce subsequently returned in Morrison's miniseries Batman: The Return of Bruce Wayne, which depicted his travels through time from prehistory to present-day Gotham. Bruce's return set up Batman Incorporated, an ongoing series which focused on Wayne franchising the Batman identity across the globe, allowing Dick and Damian to continue as Gotham's Dynamic Duo. Bruce publicly announced that Wayne Enterprises will aid Batman on his mission, known as "Batman, Incorporated". However, due to rebooted continuity that occurred as part of DC Comics' 2011 relaunch of all of its comic books, The New 52, Dick Grayson was restored as Nightwing with Wayne serving as the sole Batman once again. The relaunch also interrupted the publication of Batman, Incorporated, which resumed its story in 2012–2013 with changes to suit the new status quo.

During The New 52, all of DC's continuity was reset and the timeline was changed, making Batman the first superhero to emerge. This emergence took place during Zero Year, where Bruce Wayne returns to Gotham and becomes Batman, fighting the original Red Hood and the Riddler. In the present day, Batman discovers the Court of Owls, a secret organization operating in Gotham for decades. Batman somewhat defeats the Court by defeating Owlman, although the Court continues to operate on a smaller scale. The Joker returns after losing the skin on his face (as shown in the opening issue of the second volume of Detective Comics) and attempts to kill the Batman's allies, though he is stopped by Batman. After some time, Joker returns again, and both he and Batman die while fighting each other. Jim Gordon temporarily becomes Batman, using a high-tech suit, while it is revealed that an amnesiac Bruce Wayne is still alive. Gordon attempts to fight a new villain called Mr. Bloom, while Wayne, regains his memories with the help of Alfred Pennyworth and Julie Madison. Once with his memories, Wayne becomes Batman again and defeats Mr. Bloom with the help of Gordon.

The timeline was reset again during Rebirth, although no significant changes were made to the Batman mythos. Batman meets two new superheroes operating in Gotham named Gotham and Gotham Girl. Psycho-Pirate gets into Gotham's head and turns against Batman, and is finally defeated when he is killed. This event is very traumatic for Gotham Girl and she begins to lose her sanity.

Batman forms his own Suicide Squad, including Catwoman, and attempts to take down Bane. The mission is successful, and Batman breaks Bane's back. Batman proposes to Catwoman.

After healing from his wounds, an angry Bane travels to Gotham, where he fights Batman and loses. Batman then tells Catwoman about the War of Jokes and Riddles, and she agrees to marry him. Bane takes control of Arkham Asylum and manipulates Catwoman into leaving Wayne before the wedding. This causes Wayne to become very angry, and, as Batman, lashes out against criminals, nearly killing Mr. Freeze.

Batman learns of Bane's control over Arkham and teams up with the Penguin to stop him. Bane captures Batman, and Scarecrow causes him to hallucinate, although he eventually breaks free. Batman escapes and reunites with Catwoman, while Bane captures and kills Alfred Pennyworth. Batman returns and defeats Bane, although too late to save Alfred. Gotham Girl prompts him to marry Catwoman.

It is revealed that the Joker who was working for Bane was really Clayface in disguise. The real Joker has been plotting a master plan to take over Gotham. This plan comes to fruition during The Joker War, in which Joker takes over the city. Batman defeats the Joker who vanishes after an explosion. Ghost-Maker, an enemy from Batman's past, appears in Gotham, and, after a battle, becomes a sort of ally to Batman. A new group called the Magistrate rises up in Gotham, led by Simon Saint, whose goal is to outlaw vigilantes such as Batman. At the same time, Scarecrow returns, fighting Batman. During Fear State, Batman battles and defeats both Scarecrow and the Magistrate's Peacekeepers.

The character of Batman has been portrayed in numerous alternative versions across various media since his debut in 1939. These adaptations explore different facets and interpretations of the character.

In the "Smallville" a television series, Bruce Wayne adopts the Batman persona in 2001, later teaming up with Superman and other superheroes. Frank Miller's influential series, "The Dark Knight Returns," reimagines Batman as an older, more hardened vigilante, coming out of retirement to fight crime in a dystopian future.

In the "Injustice: Gods Among Us" universe, Batman leads a resistance against a tyrannical Superman who has taken control of Earth.

The DC Bombshells series sets Batman in a World War II-era context, with Bruce Wayne taking inspiration from Batwoman to become the masked hero. The "Dark Multiverse" introduces various twisted versions of Batman, such as the Batman Who Laughs, a hybrid of Batman and the Joker, and Red Death, a fusion of Batman and the Flash.

Other notable reimaginings include JLA/Avengers, where Batman appears in a crossover with Marvel's Avengers; Stan Lee's Just Imagine, which offers a completely different origin for Batman; and "Kingdom Come," where an older Batman operates in a dystopian future alongside other aged superheroes.

In "Superman: American Alien," Bruce Wayne's journey is retold with significant differences, and "Batman: White Knight" explores a reality where the Joker is cured of his insanity and seeks to expose Batman as the true villain of Gotham. These various adaptations and reinterpretations highlight the versatility and enduring appeal of Batman as a character, allowing for a rich exploration of his mythology across different narratives and settings.

Batman has ascended to the status of a global pop culture phenomenon, transcending his origins in comic books. His influence expanded notably with the release of the 1989 film, which propelled him to the forefront of public consciousness through widespread merchandising. The Guardian describes Batman as emblematic of the constant reinvention characteristic of modern mass culture, embodying both iconic status and commercial appeal, making him a quintessential cultural artifact of the 21st century.

Apart from comics, Batman's presence spans various mediums, including newspapers, radio dramas, television, stage, and film. From the 1940s serials to contemporary TV shows like "Gotham" and "Titans," Batman's legacy endures. Celebrating the character's 75th anniversary, Warner Bros released "Batman: Strange Days," showcasing his timeless appeal.

In September 2024, Batman become the first superhero to be given a star on the Hollywood Walk of Fame. It was the 2,790th star.

Gay interpretations of Batman have been studied academically since psychologist Fredric Wertham's claims in 1954. Andy Medhurst and Will Brooker have explored Batman's appeal to gay audiences and the validity of a queer reading. Meanwhile, in psychological interpretations, Dr. Travis Langley sees Batman as representing the "shadow archetype," confronting inner darkness to fight evil, according to Carl Jung and Joseph Campbell's theories. Langley's analysis adds depth to Batman's psychological complexity.
