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.

Darth Sidious was a human male Dark Lord of the Sith who served as the last Supreme Chancellor of the Galactic Republic and as the Emperor of the Galactic Empire. Sidious, born Sheev Palpatine, was trained in the dark side of the Force by Darth Plagueis. Eventually, Sidious took on his own apprentice, Darth Maul, and killed his master. As he continued to train Maul, Sidious came into contact with Count Dooku of Serenno, a member of the Jedi Order, who helped further Sidious' plans. In his public persona, Sidious was the unassuming Senator Palpatine of Naboo, a position he used to manipulate galactic events to his own design.

Thirteen years before his Imperial ascent, Sidious engineered the Invasion of Naboo and used the political crisis as a pretext to being elected Supreme Chancellor by the Galactic Senate. With Maul's defeat at the hands of the Jedi, Sidious was in need of a new apprentice. Dooku left the Jedi Order and was bestowed the title "Darth Tyranus" by Sidious. Together, they formed the Confederacy of Independent Systems to spark a galactic civil war. As Chancellor Palpatine, Sidious was given sweeping central, emergency powers to handle the Separatist crisis, and he raised the Grand Army of the Republic to fight the Clone Wars. The clone troopers in the Grand Army had been secretly commissioned by the Sith, and each contained a bio-chip with a preprogrammed protocol to eliminate the Jedi, the sworn enemies of the Sith, when the order was given.

At the war's end, Sidious had gained almost total control over the Republic. With his new power, Sidious branded the Jedi as traitors and ordered the clones to execute Order 66, thus destroying the Jedi Order. With the Jedi destroyed, Sidious declared himself Emperor and transformed the Republic into the Galactic Empire. Sidious also turned Jedi Knight Anakin Skywalker, the Chosen One, to the dark side and anointed him Darth Vader. Over the next several years, Sidious transferred the daily management of the Empire to a Ruling Council and spent much of his time in an ancient Sith shrine beneath the Imperial Palace, attempting to use the dark side to reshape the Force to his own ends.

Meanwhile, the Empire expanded across the galaxy, including the building of the Death Star to maintain order and act as a symbol of fear. However, the Rebel Alliance was formed to resist Sidious' rule, and the Death Star was destroyed by Luke Skywalker. Sidious tasked Vader, Skywalker's father, with either destroying or turning the boy, and Vader ultimately brought Skywalker before his master during the Battle of Endor. There, Sidious attempted to turn Skywalker to the dark side, but Skywalker refused. As Sidious attempted to kill Luke, Vader was redeemed and turned on his master, killing himself and Sidious in the process. Through redemption, Anakin Skywalker destroyed the Sith, while the Rebels successfully destroyed the Death Star II.
