The LEGO Batman Movie
In the opening of the film, Joker and his men hijack a plane containing several tons of explosives, planning on using them to destroy Gotham City. When the pilot of the plane doesn't believe that Joker's plan will work, based on the fact that's he's tried to destroy Gotham dozens of times and has always been defeated by Batman, Joker informs him that his plan will work this time as he's had his minions take over the Gotham Nuclear Plant, plant a bomb powerful enough to destroy the city on to it and had Egghead cover the Bat-signal in eggs to prevent Batman from arriving.

With Joker and his minions threatening to destroy Gotham and Batman not being able to help, Commissioner Gordon and the GCPD are forced to surrender the Mayor of Gotham to Joker and his henchmen, however, unknown to them, the Mayor was actually Batman in disguise. As Batman begins to effortlessly pummel his minions, Joker begins to become frustrated as they're making him look bad in front of him. As Joker's bomb begins to reach the end of it's countdown, his minions abandon the plant and Joker uses his balloons to try and evade Batman, however, he grabs Joker with his grappling hook and uses another hook to hold them in place. When Joker refers to himself as his greatest enemy, Batman shuts him down and tells him that he means absolutely nothing to him and that Superman is a better arch-nemesis, despite him not being a bad guy. Batman eventually lets the heart broken Joker go in order to defuse the bomb.

While in his lair, a frustrated Joker laments to Harley Quinn about how Batman doesn't respect him as a villain and how incompetent his minions are, all while watching an interview between Superman and Lois Lane. When Superman talks about how he was forced to imprison General Zod inside the Phantom Zone, he also mentions how the Zone has some of the most evil villains of all time housed inside it, and Joker comes up with a new plan.

During Commissioner Gordon's retirement party, Joker and his minions arrive and Joker orders Mr. Freeze and Clayface to bring him the new commissioner, Barbra Gordon, all while Harley Quinn changes into her civilian identity of Harleen Quinzel. However, Barbra fights off Joker's minions and confronts him at the same time as Batman and Joker reveals that he actually wants to be arrested and go to jail for his crimes, to the surprise of everyone, including his minions. While Batman is in complete denial of Joker's willingness to be imprisoned, he insists he is serious and imprisons all of his minions inside a giant present box.

With Joker and all of the other villains in jail, Batman sinks into a depression and spies on him and the other inmates, believing them to be up to something. At this point, Joker has Harleen drive up to Arkham Asylum with a van for "Phantom Zone Laundry" and Batman is inspired to put Joker in the Phantom Zone to keep him from committing crimes for good.

After stealing the Phantom Zone projector from the Fortress of Solitude, Batman and his adopted son Dick Grayson try to sneak it into Arkham, but are caught and are forced to fight through Arkham's security in order to get to Joker's cell. Batman confronts Joker and sends him to the Phantom Zone, but is arrested and locked in a cell shortly afterwards.

After being scanned for how evil he is, Joker meets the other prisoners of the Phantom Zone; Voldemort, Sauron, King Kong, The Wicked Witch of the West, The Daleks, Agent Smith, The Kracken, Medusa, and the Gremlins. Upon his arrival, the villains try to kill Joker, but he tells them all that he can get them out of the Phantom Zone and they agree to work for him in exchange. At that moment, Harley Quinn steals the Phantom Zone projector and sets it to release all of the villains entrapped in the zone. Upon doing this, Joker, as a giant face over the city, tells Gotham that he is going to take over the city with the help of real villains before unleashing them on the city.

Joker then has Sauron tell him the location of the Batcave and, after failing to realize that Bruce Wayne and Batman are the same person, he trashes the cave and converts Wayne Island into an amusement park. After Batman, Dick, Barbra Gordon and Alfred evade his attacks, destroy Sauron and crash land on Joker Island, Batman has the Bat-plane take his friends away from the island so he can stop Joker without endangering them. After being caught by Joker and his minions, Joker tries to get him to admit that he is his most hated enemy, but Batman refuses and is banished to the Phantom Zone. Joker and his minions then leave the Island and prepare to use Joker's bomb to destroy the city.

Upon being released with the promise that he will return all the escaped criminals, Batman teams up with Dick, Barbra and Alfred, along with all the escaped villains to take down Joker and his minions. After the Phantom Zone villains are re-imprisoned and the city is blown up by the bomb, Batman convinces Joker to help him save the city by admitting that he truly is his greatest enemy. Upon saving the city, Joker and Batman's villains walk away as Batman gives them a 30 minute head start.
