Joker (character)

• 1. Introduction

  ›

  On the 25th of April 1940, a grinning figure stepped out of the pages of Batman #1 and into comics history. The Joker arrived not as a sidekick or a supporting player, but as a full-blown serial killer who announced his victims in advance, poisoning Gotham's millionaire Henry Claridge before anyone could stop him. His face frozen in a grotesque, permanent smile, he left a trail of bodies wearing the same grotesque grin. What makes the Joker so enduring is not the violence. It is the unresolved questions he carries. Who made him? What made him? Does he even know himself? The most successful supervillain in comics history was nearly killed off in his second appearance, saved only by a hastily drawn panel slipped in at the last moment by an editor who saw something worth preserving. That impulsive rescue set in motion eight decades of murder, mayhem, and philosophical chaos.

• 2. A Disputed Birth

  ›

  Bill Finger, Bob Kane, and Jerry Robinson all told different stories about the night the Joker was invented, and none of them ever agreed. Robinson, who Kane had hired as a 17-year-old assistant in 1939 after spotting him wearing a white jacket decorated with his own illustrations, said the concept began with a sketch of a joker playing card from a deck he kept close at hand. He wanted a villain unlike any crime lord or gangster, someone exotic and enduring who could test Batman issue after issue. In a 1975 interview in The Amazing World of DC Comics, he recalled his thinking: "I wanted somebody visually exciting. I wanted somebody that would make an indelible impression, would be bizarre, would be memorable like the Hunchback of Notre Dame or any other villains that had unique physical characters."

  Finger's contribution was the face. He remembered a cheap Grosset and Dunlap edition of Victor Hugo's The Man Who Laughs, a novel about a man whose face had been surgically altered into a permanent grin, and cut a photograph of Conrad Veidt playing that character in the 1928 film adaptation. That image, passed to Kane, turned a rough clown sketch into something genuinely sinister. Kane later claimed the Veidt photograph came first and Robinson's card sketch was only ever a prop used in the character's early stories. Robinson maintained that his concept sketch preceded the Veidt reference entirely.

  By 2011, all three men had died, and the dispute remained unsettled. Many comic historians credit Robinson with the initial concept and Finger with shaping the character's personality. Kane, who spent his career refusing to share credits for characters, denied Robinson's claims for the rest of his life.

  The Comics Code Authority arrived in 1954, born out of the backlash inspired by Frederic Wertham, who argued in public that comic books were fueling juvenile delinquency, violence, and homosexuality. Parents organized. Books were burned. The Code banned gore, innuendo, and excessive violence, and the Joker was its most visible casualty. A character who had killed dozens, derailed a train, and poisoned Gotham's prominent citizens became a goofy thief whose most ambitious scheme involved kidnapping Robin and being foiled by a check he could not cash without getting arrested.

  The transformation stuck until Julius Schwartz, who openly disliked the character, became Batman's editor in 1964 and effectively benched him. The goofy prankster version of the Joker then found new life in the 1966 television series Batman, where Cesar Romero played him as a cackling schemer. The show's popularity forced Schwartz to keep the comics similarly light, but when the series ended in 1969, the audience that had followed the TV Joker did not migrate to the comics, and sales continued to fall.

  In 1973, writer Dennis O'Neil and artist Neal Adams brought the character back in Batman #251's "The Joker's Five-Way Revenge" as something closer to his original self. O'Neil said his research was simple: he went to the DC library, read the early stories, and tried to recover what Kane and Finger had originally intended. Adams extended the Joker's jaw and made him taller and leaner. O'Neil also introduced the legal framework that would define the character for decades: the Joker was not imprisoned but committed, because he was legally insane, sent to Arkham Asylum rather than a cell.

• 4. The Killing Years

  ›

  Steve Englehart and Marshall Rogers produced eight issues in Detective Comics #471-476 between August 1977 and April 1978, and those stories set the template for almost everything that followed. "The Laughing Fish" depicted the Joker chemically disfiguring fish to bear his trademark grin and then attempting to file for copyright protection, a scheme that collapsed because no bureaucrat in Gotham could explain to him that natural resources cannot be trademarked. Englehart described his goal plainly: "I really wanted to get back to the idea of Batman fighting insane murderers at 3 a.m. under the full moon, as the clouds scuttled by."

  Those eight issues influenced the 1989 Batman film and were directly adapted for the 1992 animated series. But it was the late 1980s that produced the stories most permanently marked by the Joker's capacity for damage. In 1988's "A Death in the Family", DC Comics put Jason Todd's fate to a reader vote. Todd was unpopular. The margin was 72 votes. The Joker beat him with a crowbar and left him in a room with a bomb. The result altered the Batman universe permanently: a core character, not an anonymous bystander, had died.

  The same year, Alan Moore and Brian Bolland published The Killing Joke, which paralyzed Barbara Gordon and tortured her father, Commissioner James Gordon, as an attempt by the Joker to prove that one bad day could break any normal person. Critics have called it one of the greatest Joker stories ever written. Moore's graphic novel also offered the most frequently cited origin: a failed stand-up comedian, desperate to support his pregnant wife, agreeing to one criminal job as the Red Hood, and falling into a chemical vat when Batman arrives to stop him. The Joker himself undercuts the whole story, admitting he does not remember exactly what happened and that he prefers his past to be "multiple choice".

• 5. No Fixed Origin

  ›

  Detective Comics #168, published in February 1951, gave the Joker his first backstory: a laboratory worker who became the masked criminal Red Hood to steal a million dollars and retire. Batman thwarted him, he fell into a chemical vat, and the disfigurement drove him insane. That story held for decades as the canonical version, but the character's unreliable memory has always left the door open.

  The Killing Joke expanded and complicated that account. Paul Dini and Alex Ross's "Case Study" offered an entirely different reading, describing the Joker as a sadistic gangster who was already sane and who researches his crimes to appear mentally ill in order to avoid the death penalty. Batman Confidential #7-12 told yet another version, in which a bored career criminal named Jack becomes obsessed with Batman during a heist and manufactures his own disfigurement through a series of increasingly reckless provocations.

  The 2020 miniseries Batman: Three Jokers, written by Geoff Johns with art by Jason Fabok, proposed that there were in fact three distinct Jokers operating over the decades: "The Criminal," based on the Golden Age version; "The Clown," based on the Silver Age prankster; and "The Comedian," the sadistic psychopath of the Modern Age. The Comedian kills the other two and does not confirm whether he is the original. Chip Zdarsky's subsequent run on Batman reinterpreted the three Jokers as separate personalities the character built within his own mind under the influence of a shared mentor, Doctor Daniel Captio, claimed by the story to have trained both Bruce Wayne and the Joker. The 1966 story "Payback" gave the Joker the first name "Jack". Three Jokers established that his wife did not actually die during his origin but was relocated to Alaska by Gotham police and Batman to protect her from him.

• 6. Weapons and Psychology

  ›

  The Joker's lapel flower and joy buzzer first appeared in 1952 as harmless novelties. By later stories, the flower sprayed acid and the buzzer conducted a million volts. His signature weapon, "Joker venom," has been present since his debut in 1940; only he knows its formula, and he has demonstrated the ability to manufacture it from ordinary household chemicals. The toxin induces uncontrollable laughter, and higher doses cause paralysis, coma, or death, leaving the victim's face locked in the same rictus grin the Joker wears. A modified version of the venom, used in Joker: Last Laugh in 2001, converted its victims into Joker-like subordinates.

  Grant Morrison, writing in Batman #663 in April 2007, attributed the Joker's immunity to most poisons to "years of dedicated abuse" as an "avid consumer of his own chemical experiments." In the same issue, Morrison depicted the Joker entering a meditative state to consciously redesign his own personality, effectively constructing himself from scratch according to his current needs. Arkham Asylum: A Serious House on Serious Earth, published in 1989, described the character as able to process external reality only by adapting to it moment by moment, which is why he can function as a mischievous clown one day and a methodical killer the next.

  When Scarecrow dosed him with fear toxin in the 1993 story Knightfall, the Joker laughed and said "Boo!" Comics scholar Peter Coogan described the character as attempting to reshape reality by imposing his face on his victims, as a means of making the world comprehensible by filling it with versions of himself. The Joker described in The Joker: Devil's Advocate in 1996 was said to have killed over 2,000 people, yet he is consistently found not guilty by reason of insanity and returned to Arkham.

• 7. Batman's Mirror

  ›

  The Joker and Batman are constructed as opposites in almost every dimension. Batman is introverted, monochromatic, and represents order. The Joker is extroverted, colorful, and embraces chaos. Batman is wealthy; the Joker rejects material accumulation entirely. The Joker's crimes in Batman #1 in 1940 were directed against Gotham's wealthiest citizens and the judge who had imprisoned him.

  In Frank Miller's The Dark Knight Returns from 1986, the Joker is depicted as a lipstick-wearing celebrity who is functionally inert without Batman. In the 1994 story "Going Sane," the Joker attempts to live a normal life after Batman's apparent death and only reverts to his old self when Batman returns. In "Emperor Joker" in 2001, a Joker with near-omnipotent power finds he cannot destroy the universe because doing so would require destroying Batman, and without Batman, winning means nothing.

  Writer Peter Tomasi and the "Death of the Family" arc by Scott Snyder and artist Greg Capullo in 2012 both describe the Joker as effectively in love with Batman, though not romantically. The Joker believes Batman has not killed him because he makes Batman better. His refusal to learn Batman's secret identity, despite multiple opportunities, follows from this logic: he has no interest in the person behind the mask. The 2014 "Endgame" storyline by Snyder and Capullo implied the Joker had been living for centuries in Gotham as a repeated cause of tragedy, exposed to a regenerative substance he called "dionesium." The story ended with both Batman and the Joker apparently killing each other, then both being revived in a Lazarus Pit, stripped of their memories.

  Jack Nicholson's portrayal of a Joker named Jack Napier in Tim Burton's 1989 Batman earned the film over $400 million at the worldwide box office. Film critic Roger Ebert noted that audiences sometimes had to remind themselves not to root for the Joker over Batman. Mark Hamill began voicing the character in 1992's Batman: The Animated Series and became so associated with the role that he reprised it across dozens of projects over the following three decades, including video games, animated films, and amusement-park recordings. Hamill announced his retirement from the role following the death of Kevin Conroy in 2022; Conroy had voiced Batman opposite Hamill's Joker since the animated series began.

  Heath Ledger's portrayal in 2008's The Dark Knight earned a posthumous Academy Award for Best Supporting Actor, the first acting Oscar ever awarded for a superhero film. The Dark Knight grossed over a billion dollars and was the highest-grossing film of the year. Joaquin Phoenix won an Academy Award for Best Actor for the 2019 film Joker, which also crossed a billion dollars at the box office. Phoenix reprised the role in Joker: Folie a Deux in 2024, in which Arthur Fleck is killed by a young Arkham inmate played by Connor Storrie, who carves a Glasgow smile into his own face and is implied to be the character who will become the "real" Joker.

  In 2006, Wizard magazine ranked the Joker first on its list of the 100 greatest villains of all time. In 2015, The Joker: A Serious Study of the Clown Prince of Crime became the first academic book published about a supervillain. The character that an editor saved from death with a hastily drawn panel in 1940 had become, as the Trickster put it in the 1995 miniseries Underworld Unleashed, the story supervillains tell each other when they want to scare themselves.
