Eine Preisverleihungsparty für Gotham Citys Mann des Jahres Bruce Wayne versinkt im Chaos, als der Joker auftaucht und mit ihm eine ganze Galerie von Schurken, inklusive dem Riddler, Catwoman und Two-Face. Der dunkle Ritter tritt in Aktion, um die ungebetenen Gäste einzufangen. Aber ein Krimineller ist nicht so offensichtlich – Lex Luthor und mit ihm eine geheime Waffe, die die Machtbalance in Gotham für immer verschieben kann: der Deconstructor. Lex Luthor und der Joker – ob der starrköpfige Batman und Robin mit diesem gefährlichen Team alleine fertig werden? Andererseits: Wofür hat man denn Super-Freunde? Superman, Wonder Woman, Green Lantern und die Justice League schließen sich dem Kampf gegen das Böse an. Sie stürzen sich in die Action, um die Unschuldigen zu beschützen, Gotham City zu retten und nebenbei auch mal zu lachen. Entdecke brandneue aufregende Momente, die bisher im Videospiel nicht zu sehen waren. Dies ist der erste LEGO Batman-Film und – wer weiß – vielleicht hat auch der Dunkle Ritter dabei ein bisschen Spaß.
Nachdem sich Lex Luthor und der Joker verbündet haben, scheint es nur noch eine Frage der Zeit, bis sie ihren Plan vom Weltuntergang verwirklichen können. Batman hat sich in den Kopf gesetzt, die Schurken im Alleingang aufzuhalten. Doch irgendwann muss selbst er einsehen, dass es vielleicht doch besser wäre, auf die angebotene Hilfe von Superman, Wonder Woman, Green Lantern und dem Rest der Justice League zurückzugreifen."Riddle me this, riddle me that. Who's afraid of the big black bat?" ―The Riddler to Batman. The Riddler was the chosen alias of criminal genius Edward Nygma. After he was rejected by his idol, Bruce Wayne, for one of his inventions, Nygma turned to crime and used his scientific knowledge for evil. "I'm sucking up your IQ, vacumming the cortex, feeding off your brain." ―Edward Nygma sing-songingly taunting his boss, Fred Stickley, while utilizing his neural energy. Edward Nygma became a researcher under the employment of Wayne Enterprises, and developed a device to beam television directly to a person's brain.
Bruce Wayne, Nygma's secret idol, was convinced that mind manipulation would raise too many questions, and turned the idea down, but Nygma continued to work on it after hours. When Fred Stickley, the head of the research department, discovered Nygma's clandestine overtime, Nygma knocked Stickley unconscious, tied him to a chair, used him to test his device, and discovered that he could use it to absorb people's knowledge. After he realized that Bruce Wayne was right about it being mind manipulation, Stickley fired Nygma, but Nygma murdered Stickley, altered the security tapes to make Stickley's death look like a suicide, and then resigned from Wayne Enterprises. Nygma, who stalked Wayne and left riddles for him, was inspired and delighted by watching Two-Face's raid at the circus on live television and created his own alter-ego in the form of The Riddler, a master of puzzles and quizzes. Nygma perfected his brain-manipulation device into a system, "The Box", which beamed signals to and from the human brain in order to simulate an immersive television-viewing experience.
That had the side effect of allowing the Riddler to read viewers' minds, as well as augment his own intelligence. Using his device, the Riddler found Two-Face at his hideout, and proposed a deal that would benefit them both: they would mass-produce the brain-manipulation device to become Gotham's clever carbon-based lifeforms and discover Batman's true identity so that they could use it to their advantage to plot out his downfall. Seeing the advantage of the device, Two-Face agreed (due to his coin flip marking heads in favor of the deal), and they became partners-in-crime in order to fund mass-production of the device. With enough capital to start mass-production of his invention, the Riddler readopted his Edward Nygma identity, opened his own business company that was called NygmaTech, and sold thousands of his devices to many of Gotham's citizens, who found his inventions very impressive. The Riddler then built his main base of operations on Claw Island, which was ten miles away from Gotham City.
Since the Box was considered popular to many of Gotham's citizens, that allowed NygmaTech to gain more profit, and the Riddler started to feed on the citizens' minds every time they used his inventions to make himself more intelligent; and he even allowed Two-Face to receive his share of feeding off the citizens' minds, which made Two-Face more intelligent as well. Following his successful marketing of the invention, Nygma hosted a launch event for a set-top version of his device, to which many citizens attended, including Bruce Wayne himself. Nygma convinced an unwitting Bruce to try it, which resulted in Riddler and Two-Face inally discovering his alter ego as Batman, much to their delight. On the night of Halloween, Riddler and Two-Face later converged upon Wayne Manor, where Riddler discovered the location of the Batcave. Riddler destroyed the Batcave and all of its equipment with bat shaped bombs while Two-Face shot at Bruce, which grazed his head with a bullet and left him unconscious.
Two-Face attempted to finish Bruce off with a second bullet, but the Riddler talked him out of it, stated that "If you kill 'im, he won't learn nothin'." and left a final riddle for Bruce, while Two-Face ordered his thugs to kidnap Dr. Chase Meridian. After Bruce regained consciousness, he and eventually solved the greater riddle that was concealed in the riddles that were left for them when they noticed that each one had a number in it: 1. "If you look for numbers on my face, you won't find thirteen any place." 2. "Tear one off and scratch my head; what was once red is black instead." 3. "The eight of us go forth, not back, to protect our king from a foe's attack." 4. "We're five little items of an everyday sort; you'll find us all in 'a tennis court'." Each number corresponded to a letter in the alphabet, with 1 and 8 that were digits for the number 18. 13 being "M", 18 for "R" and 5 for "E", M-R-E, or "Mr. E"- mystery, or enigma- Mr. E. Nygma. After he changed into Batman in the sole remaining Batsuit, a prototype with sonar-imaging lenses that were built into the cowl, Bruce asked Alfred whether he should use the Batboat or the Batwing.
Dick Grayson suggested both as he entered the Batcave- and was dressed in a "Robin" costume of Alfred's design. Bruce decided that two against two were better odds, and finally agreed to Dick becoming a partner. Meanwhile, back at Claw Island, the captive Dr. Meridian told the Riddler that Batman would come for her, but upon expecting to see that he would be scoffing at it, Riddler instead admitted that he was actually counting on Batman to come as part of his plan. Batman and Robin used both vehicles to enter the aquatic lair; however, both of their vehicles were destroyed by the Riddler and Two-Face. The heroes ended up swimming to an island that was made of metal, where they were then separated. Batman fought his way through the Riddler's deadly traps, while Robin finally fought Two-Face. Robin managed to send Two-Face over the edge of a ledge, where he clung on to for dear life. After he realized that he would rather have Two-Face arrested and locked up for life than kill him, Robin helped him up instead.
Two-Face thanked Robin by pulling out a gun and trapped him. Meanwhile, Batman finally reached the Riddler, who sat in a large throne beneath the glass chamber that collected the brainwaves of Gotham's citizens, and was surrounded by obfuscating laser lights and holograms. Riddler revealed Chase and Robin, who were bound and gagged with duct tape and were imprisoned in large glass containers over a large, and deadly pit of water and metal spikes. The Riddler challenged Batman with the greatest riddle of all ("Can Bruce Wayne and Batman ever truly co-exist?"), and gave him the choice of rescuing either Chase or Robin. Batman distracted the Prince of Puzzlers with a riddle of his own. Unable to resist, the Riddler took his hand off of the control that would drop the two, sat back down on his throne, and listened eagerly. Batman gave his Riddle: "I see without seeing. To me, darkness is as clear as daylight. The Riddler scoffed and gave him the answer: "You're as blind as a bat!". The Dark Knight affirmed that answer, and activated the Batsuit's sonar-imaging lenses, which allowed him to accurately hurl a Batarang at the brain-wave hub, and shattered both it and the Riddler's massive intelligence.
Before the Riddler collapsed, he sprung the trap doors in Robin's and Chase's cages, and sent them plummeting to their apparent doom. Fortunately, Batman rescued both of them before he was confronted by Two-Face. After Two-Face fell down into the pit to his death, Batman returned to the Riddler's destroyed lair and found Edward: his mind was enfeebled by the overload of brainwaves and his body was horribly scarred from the explosion of the brain-wave hub. Taking light to his former employee's plight, Batman finally answered Nygma's riddle and said: "". Just as Batman moved closer to him, the Riddler screamed in terror as he experienced Bruce's memory of the first bat that ever terrified him. With both of the villains defeated, Batman turned Nygma to the GCPD, who then sentenced him to be committed at Arkham Asylum for his crimes against Gotham, and his company was sunk. Chase was asked to consult on Nygma's case by Dr. Burton after she was told that he had screamed for hours that he knew who Batman was.
After she wondered if the Riddler had indeed remembered the information that was taken from Bruce's brain that concerned Batman's identity, Chase went to his cell. Chase identified herself and then asked Riddler if he remembered her. When he answers affirmatively, the Riddler offered to reveal the identity of Batman to Chase if she said "please". Chase did so, and the Riddler responded by telling her that he himself was Batman, and as if to prove his point, he started to flap his arms as if to imitate a bat while he laughed manically; his stolen memories were scrambled upon the brain wave hub's destruction. At that point, Chase came out to tell Bruce that his secret was safe, and confirmed that Nygma was a complete lunatic. A couple of years later, when Mr. Freeze was held at Arkham Asylum, one of Nygma's Riddler outfits was held in the Criminal Property Locker, along with one of Two-Face's, when Poison Ivy and Bane broke Freeze out. The filmmakers claimed they were indeed aware of reports that Jim Carrey and Tommy Lee Jones had "stolen the show."
