So... let's start
Number 10: Hugo Strange
Hugo Strange first appears as a scientist who uses a stolen "concentrated lightning" machine to generate a dense fog every night, allowing his gang to rob banks unseen, though he knows Batman poses a threat to him. Batman, who already knows of Strange's experiments, begins investigating him after one of his henchmen kills a man. When his henchmen are apprehended, Strange vows to set a trap for Batman at the next target on the list. When Batman arrives, over a dozen of Strange's men are waiting for him, and one of them knocks him out with a blackjack. He wakes up in Strange's lair, where Strange hangs him from his wrists and lashes him with a whip. Batman breaks the ropes, gasses the room, and tackles Strange, who is jailed but plans to escape. In Hugo's second appearance he escapes from the "city asylum" with a gang of criminals, then breaks out "five insane patients" and uses them as test subjects, turning them into hulking 15 ft zombies by administering a powerful artificial growth hormone that acts on the pituitary gland. They wear bulletproof clothing, and he releases them to wreak havoc in Gotham City while his men commit robberies. Strange administers the serum to Batman after the giants capture him, saying it will work in 18 hours. Batman tricks two of the monsters into killing each other, and then saves himself by creating a drug that prevents any abnormal secretions from the pituitary gland. He is then able to kill all the other monsters, and sends Strange to his apparent demise, although he suspects that the mad scientist has survived. In Detective Comics #46 Strange starts spreading a fear-inducing powder around the city until a punch from Batman sends him falling to his apparent death.
Number 9: Man-Bat
Dr. Kirk Langstrom, a scientist specializing in the study of bats (chiropterology), develops an extract intended to give humans a bat's sonar sense and tests the formula on himself because he is becoming deaf. The extract works, but it has a horrible side effect: it transforms him into a hideous man-sized bat. The serum also takes away his intelligence, so he goes on a mad rampage until Batman can find a way to reverse the effects.
Number 8: Two Face
Once an upstanding district attorney of Gotham City and an ally of Batman, Harvey Dent goes insane after a mob boss throws acid at him during a trial, hideously scarring the left side of his face. He adopts the "Two-Face" persona and becomes a criminal, choosing to bring about good or evil based upon the outcome of a coin flip. Originally, Two-Face was one of many gimmick-focused comic book villains, plotting crimes based around the number two, such as robbing Gotham Second National Bank at 2:00 on February 2 and stealing 2 million dollars.
Number 7: Penguin
The Penguin is depicted as being short and portly, and he is known for his love of birds and his specialized high-tech umbrellas. A mobster and thief, he fancies himself as being a "gentleman of crime"; his nightclub business provides a cover for criminal activity, which Batman sometimes uses as a source of criminal underworld information. According to Kane the character was inspired from the then advertising mascot of Kool cigarettes – a penguin with a top hat and cane. Finger thought the image of high-society gentlemen in tuxedos was reminiscent of emperor penguins.
Number 6: Catwoman
The original and most widely known Catwoman is Selina Kyle. The character was partially inspired by Kane's cousin, Ruth Steel, as well as actress Jean Harlow. In her first appearance, she was a whip-carrying burglar with a taste for high-stake thefts. For many years the character thrived, but from September 1954 to November 1966 Catwoman took an extended hiatus due to the newly developing Comics Code Authority in 1954. These issues involved the rules regarding the development and portrayal of female characters that were in violation of the Comics Code, a code which is no longer in use. In the comics, two other women have adopted the Catwoman identity, apart from Selina: Holly Robinson and Eiko Hasigawa.
Number 5: The Riddler
The Riddler is obsessed with riddles, puzzles, and word games. He frequently delights in over-stating his "intellectual superiority" and on forewarning both Batman and the police of his capers by sending them complex clues. With this self-conscious use of a gimmick, Riddler's crimes are flamboyant and ostentatious. The character is depicted as wearing a domino mask either with a green suit and bowler hat, or a green unitard with question mark prints. A black, green, or purple question mark serves as his visual motif.
The Riddler was popularized by Frank Gorshin’s Emmy-nominated portrayal in the 1960s Batman television series. Jim Carrey played the Riddler in the 1995 film Batman Forever with Gorshin as his inspiration. The character was also featured in Batman: The Animated Series (voiced by John Glover) and The Batman (voiced by Robert Englund). In both series, he was portrayed as a smooth-talking intellectual who presented genuinely challenging riddles. Since Batman: The Animated Series and Batman Forever, Riddler often carries a trick "question mark" cane.
Number 4: Poison Ivy
Poison Ivy is depicted as one of the world's most notorious eco-terrorists. She is obsessed with plants, botany, and environmentalism. She uses toxins from plants and mind controlling pheromones for her criminal activities, which are usually aimed at protecting the natural environment. Fellow villain Harley Quinn became her recurring partner-in-crime and her best friend. She has proven to be one of Batman's more powerful foes, as she is one of the few members of the Dark Knight's Rogues Gallery to display anything close to superpowers. The character has been portrayed as a love interest for Batman in some comics. In one comic, she was robbing a charity gala Bruce Wayne and Barry Allen were attending. Her first kiss was poison, the second its antidote. When they first meet, her toxic lips planted a seed of toxic rapture in Bruce. But when she later kissed a dying Dark Knight, she unknowingly cured her intended victim and established a budding romantic tension between them.
Creator Robert Kanigher modeled Poison Ivy after Bettie Page, giving her the same haircut and Southern drawl as Page. In her first appearances in 1966, no origin was developed; she was merely a temptress. When she first arrived in Gotham City, her costume was a one-piece, strapless green bathing suit, covered with leaves. Leaves also formed her bracelets, necklace, and crown. She wore green high heels and yellow-green nylon stockings with leaves painted on them. These particulars changed somewhat when she re-appeared.
Number 3: Mr. Freeze
Freeze is a scientist who must wear a cryogenic suit in order to survive, and bases his crimes around a "cold" or "ice" theme, complete with a "freeze gun" that freezes its targets solid. In the most common variation of his origin story, he is a former cryogenics expert who suffered an industrial accident while attempting to cure his terminally ill wife Nora Fries.
Mr. Freeze was played by George Sanders, Otto Preminger and Eli Wallach in the original Batman television series and by Arnold Schwarzenegger in the 1997 film Batman & Robin, was voiced by Michael Ansara in Batman: The Animated Series and by Clancy Brown in The Batman, and has been voiced by Maurice LaMarche in the Batman: Arkham video game franchise.
Number 2: Scarecrow
Although he only made two appearances in the Golden Age of Comic Books, the character was revived during the Silver Age of Comic Books by writer Gardner Fox and artist Sheldon Moldoff in the pages of Batman #189 (Feb 1967) and has since become a staple Batman villain. Scarecrow has been featured in other DC Comics-endorsed media such as feature films, video games, television series, and merchandise such as action figures. Irish actor Cillian Murphy portrayed Scarecrow in Christopher Nolan's Dark Knight trilogy. The character has been voiced by Henry Polic II on Batman: The Animated Series, by Jeffery Combs on The New Batman Adventures, and by John Noble in Batman: Arkham Knight. In 2009, the Scarecrow was ranked as IGN's 58th Greatest Comic Book Villain of All Time.
Number 1: The Joker
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 in response to regulation by the Comics Code Authority, before returning to his darker roots during the early 1970s. 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 antithesis of Batman in personality and appearance, the Joker is considered by critics to be his perfect adversary.
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.
