I don't know if you all know the Famous Joker. The Joker is a fictional supervillain created by Bill Finger, Bob Kane, and Jerry Robinson. The first issue of the comic book Batman (April 25, 1940) published by DC Comics. Although the Joker was planned to be killed off during his initial appearance, he was spared by editorial intervention, allowing the character to endure as the archenemy of the superhero Batman. In his comic book appearances, the Joker is portrayed as a criminal mastermind. Introduced as a psychopath with a warped, sadistic sense of humor, the character became a goofy prankster in the late 1950s. As Batman's nemesis, the Joker has been part of the superhero's defining stories, including the murder of Jason Todd—the second Robin and Batman's ward—and the paralysis of one of Batman's allies, Barbara Gordon. The Joker has had various possible origin stories during his decades of appearances. The most common story involves him falling into a tank of chemical waste which bleaches his skin white, turns his hair green, and his lips bright red; the resulting disfigurement drives him insane. The Joker possesses no superhuman abilities, instead using his expertise in chemical engineering to develop poisonous or lethal concoctions, and thematic weaponry, including razor-tipped playing cards, deadly joy buzzers, and acid-spraying lapel flowers. Although the Joker sometimes works with other supervillains such as the Penguin and Two-Face, and groups like the Injustice Gang and Injustice League, these relationships often collapse due to the Joker's desire for unbridled chaos. The 1990s introduced a romantic interest for the Joker in his former psychiatrist, Harley Quinn, who becomes his villainous sidekick. Although his primary obsession is Batman, the Joker has also fought other heroes including Superman and Wonder Woman.
One of the most iconic characters in popular culture, the Joker has been listed among the greatest comic book villains and fictional characters ever created. The character's popularity has seen him appear on a variety of merchandise, such as clothing and collectable items, inspire real-world structures (such as theme park attractions), and be referenced in a number of media. The Joker has served as Batman's adversary in live-action, animated and video game incarnations, including the 1960s Batman television series (played by Cesar Romero) and in film by Jack Nicholson in 1989's Batman, Heath Ledger in 2008's The Dark Knight, and Jared Leto in 2016's Suicide Squad. Mark Hamill, Troy Baker, and others have provided the character's voice.
Dr. Harleen Frances Quinzel, also known as Harley Quinn, first appeared in the Batman: The Animated Series episode "Joker's Favor" (episode #08, original air date: September 11, 1992) where she served as a humorous female sidekick to the Joker. In her first appearances she was depicted as a character completely devoted to the Joker, totally oblivious to his psychotic nature and his obvious lack of affection for her a characterization that has remained more or less consistent throughout her subsequent appearances. Her name is a play on the word 'harlequin'.
The origin of the character was recounted in a 1994 graphic novel The Batman Adventures: Mad Love. Told in the style and continuity of Batman: The Animated Series and written and drawn by Paul Dini and Bruce Timm (two of the producers of the animated series and Harley's creators), the comic book revealed Harley's origins as an Arkham Asylum psychiatrist who fell in love with the Joker. The story was widely praised and won the Eisner and Harvey Awards for Best Single Issue Comic of the Year.
The Mad Love story was originally thought too violent for the animated series, though it was eventually adapted in The New Batman Adventures series episode "Mad Love" in 1999. This made it the first "animated style" comic book which was adapted for the series (the other being a holiday special adapted into the episode "Holiday Knights").
The Suicide Squad, also known as Task Force X (the name of a closely related but independent supervisory organization), is a name for two fictional organizations appearing in American comic books published by DC Comics. The first version debuted in The Brave and the Bold #25 (1959), and the second version, created by John Ostrander, debuted in Legends #3 (1987).
The modern Suicide Squad is an antihero "strike team" of incarcerated, death row supervillains; acting as deniable, covert assets of the United States government, it undertakes high-risk, black ops missions in exchange for commuted prison sentences. The group operates out of Belle Reve Penitentiary, under the directorship of Amanda Waller. This concept -- of the Suicide Squad functioning as a sort of unconventional, secret prison work-release program -- helps explain why many of the DC Universe's supervillains remain perpetually on the loose, no matter how many times they are apprehended, convicted, and incarcerated for their latest crimes.
Various incarnations of the Suicide Squad have existed throughout DC Universe canon, as depicted in several self-titled comic book series, from its origins in the Silver Age, to its modern-day post-Crisis reimagining, to the current version that was introduced in the wake of DC's 2011 New 52 continuity reboot.
The group has appeared in various media adaptations, including television series and an upcoming Suicide Squad 2016 feature film, set to star Jared Leto, Margot Robbie, Joel Kinnaman, Will Smith, Jai Courtney, Viola Davis, Scott Eastwood, Jay Hernandez, Karen Fukuhara and Cara Delevingne.
