A/N: Inspired by Batman Animated Series scrapped script would deepen the Batman and Joker origins and rivalry, and numerous of sources such as Gotham TV Show and Batman: The White Knight. I do not own DC Comics' Batman or anime Code Geass. All credits goes to their owners.
It was a dark time for Japan. Their sacred lands were disturbed for ore-mining purposes. They lost their pride and their country's name. Instead they will always be branded as Area Eleven of the Holy Britannia Empire.
Meanwhile, a certain ore would be melted to be made as a firearm. The gun would fall in hands of in the hands of a mad clown. Who would spark a downfall of the Empire...
While in this parallel Code Geass AU universe; this Joker finds perfect rival: Zero or Lelouch Lamperouge.
His origins are almost directly unknown. After the supposed assassination of his mother, young Lelouch is haunted by a hideous laughter which he believes it belongs to the one who "killed" his mother (eventually, Lelouch would learn that his mother survive the ordeal...)
The Joker is appeared first as a criminal underworld assassin to later a minor mob boss. Very stylish...
"Letme present to you...one and the ONLY! THE JOKER!"
A long giggle was heard. He appears nonchalantly. Then a hideous laughter is heard. "GAHAHAHAHAHAHAHAHAHAHAHA!"
"Great Scotts!"
"Actually! I am (part) Irish!" he chuckled mysteriously.
Going behind the scenes for further influence, the Joker soon recruits Emperor Charles' distraught soldiers or mercenaries-which he takes over the whole criminal underworld or corrupt sections around the world in matter of days.
"TSK! TSK! THEN I THOUGHT THOSE TAXPAYER MONEY GOES TO THOSE GERMS!" as he gave a surprised visit to an "old" associate.
"You!" as a certain Britannian official runs for an alarm. A police box that signals the law enforcement is not far outside.
"Heh heh! That's RIGHT buddy! BRING ABOUT THOSE PRESS WHY WON'T YOU?"
The official stops in brief hesitation.
"WHY NOT A PHOTO-UP WITH THE COUNCILMAN AND HIS WACKY PAL!"
As he drastically rolls his eyes with craziness.
Soon interested in the Britannian Empire affairs-partially for its conquests which means more business as usual.
However, after finding out the whole truth about the royal family conspiracies (after carrying out the fake assassination of Queen Marianne) and to conquer Japan-he later played on both sides for arms business-and assassinated Genbu Kururugi (in front of his son instead of Suzaku killing his own father) due to "business" managements-with that he disappears which lets Britannia eventually taking over Japan.
Suzaku is haunted by the Joker's signatures-his playing cards at every heinous crimes he committed.
Soon after certain research on the Joker (whose business status is now an acquirable assassin), Lelouch meets C.C and gaining the power of Code Geass-he made his journey as Zero and sparks the rebellion in Japan (after killing his half-brother Clovis).
Meanwhile the Joker committed many ranges of crimes which ranked him from a notable serial killer (targeted certain known individuals that have gotten in his way, however the law enforcements marked them as "random", which the Joker tricks them of thinking like this) to being a terrorist/anarchist in the Chinese Federation, the Europia United, and later Britannia.
Even in the future, the United Federation of Nations mentioned about him as the "Laughing Bloody Renegade", a smiling master criminal, one-man terrorist cell, and world's most wanted.
First public appearance: as Zero himself was becoming popular, the Joker made himself known during Christmas time at Japan-using Diethard's cameras, he and his henchmen (hired goons, thugs, street gangs, gangsters, and mental psychopaths or patients-all wearing Britannia's prison straitjackets with all manner of costumes and disguises with masks) used a Christmas Tree's hidden rocket-missile into Britannia Tokyo's officials and ambassadors meeting-and robbing or massacring elite party guests.
His supposed hired hands have crazy names as their minds such as: "Puzzler", ex-Colonel Gumm, Clavicle, Cabala, Dr. "Spellcraft", Minerva, Lord "Ffogg", Peasoup, Lola, Calamity Jan, "Minstrel", Archer, "Sandman", Olga, Harry Chandell, Marsha, "Siren", "Black Widow", Zelda, "Shame", "Ma Parker", "False Face", and Louie Lilac.
He creates an announcement of going on a rampage which he remained true at his threat: Targeted Ashford Academy cheerleaders' bus, and attempted to burn it but Suzaku foiled it. But he had fun, didn't he?
"-Now then, give me an "O"!"
Everyone is still traumatized by the sudden attack.
BAM! went off his usual gun.
"I SAID GIVE ME AN "O"!"
"...o," they whimpered.
"NOW, Give me an "N"!"
"...N".
"NOW, GIVE ME ANOTHER "O"! AND WHAT THAT SPELL!? "O-NO"! HAHAHAHAHAHAHAHA!" as he sprayed them in the face full of gasoline.
Infuriated-he later tracks down Suzaku military station and infiltrated it. Massacring everyone and leaving a video message for coverage: telling everyone to "lose their sanity".
"You're all prisoners. What you call sanity, it's just a prison in your minds that stops you from seeing that you're just tiny little cogs in a giant absurd machine. Wake up! Why be a cog?! Be free like us!"
Dressed as a magician-and attacked an elder donor banquet, kidnapped business meeting members that have connections to the mayor of Tokyo, and later had the mayor himself and his intern along with Tokyo's national guard major, police commissioner, an archbishop, D.A, and a female Britannian official.
With his hostages strapped C-4 around their necks, he hijacks a concert with for a Knightframe along with monetary demands, and Suzaku for foiling his previous phrase.
After being rebuffed many times-he blew up several hostages one-by-one along with several of his men sniping at nearby civilians bystanders.
However Zero appears and intervenes, saving rest of the hostages, however during their first public confrontation-a gas blimp appears; spraying at flying Knightframe soldiers (later shot down by Suzaku). After an intense fight that lead up on the huge concert hall's roof, with Joker pulling out many of his "toys" to combat Zero and Britannia back-ups. The Joker pulls a dirk and accidentally stabs himself-and falls (laughing at his supposed death).
Zero saves his life. Angered by this twist of events, the Joker kills his two henchmen who surrounded Zero and berates him about morals and attempts to commit suicide but Zero knocks out his gun.
This delivered a punch at Lelouch's jaw and attempts to attack him with a hidden sledgehammer, but Zero returns many fleet of blows which later Joker gets himself hit by a large chime bell and hanged upside down with wires after attempting to escape with a hidden jet-pack.
The Joker demands Zero to end him, but Lelouch hesitates by his sudden wish for death. Britannia forces then moves in, causing Zero to restrain Joker and escape to his Knightframe in the process. Afterwards as the Joker spends time in prison, creating other schemes and plans. He escapes during his play in a prison ballgame, signaling a prison riot/escape, and blew up the prison's infrastructures.
Gassed many news network coverages which he installs many torture/terrorist or ransom videos (such as poisoning many at an amusement park with contaminated cotton candy after killing a Black Knight member dressed as Zero on live TV).
Demanded for Zero to turn himself in; he attacked several economy centers, bombed parliament buildings, targeted nuclear plants in Middle Eastern Federation, kidnapped Britannia's Secretary of State (foiled), directed a Britannia's secret project attack: a space-based laser weapon; that has reflective diamonds to hit Japan's intended areas (carving a "smiley face", foiled-attempted to use Plan B: firing a rocket from this universe's Alcatraz Island base across the Pacific but was fired down), rigged a bus (with Britannia's and Japan's civilians) to explode at a certain level of speed (foiled), robbed Britannia top vaults installed in Japan (trying to pin blame on Zero-foiled), unleash a laughing gas virus through medications (foiled-although a number all around the world were affected by using Smilex-contaminated hygiene products), took over many passengers airplanes, installed a bomb underneath Tokyo while singing in choir with a video game console detonator (foiled), and then sprayed gas-leaked laughing bombs into Japan's subways vents and trains (foiled).
Went on as a spree killer/mass murderer, slaughters anyone who values momentum than tradition, massacred public areas in neutral countries around the world with mini or gadding-guns, makes "art" by killing people, killed many civil or city officials with "style", or blowing up cities' landmarks.
He orchestrated the theft of a large shipment of ammonium nitrate, used clever-vandalism of portraying him in many images of history, sabotaged weapons, targeted and hacked many areas at once such as world's economy necessities to collapse-foiled, destroyed gang activity areas, society would been thrown in state of anarchy. Even hijacking vehicles to cause random chaos and many gigantic Knightmare Frames...
Soon in recent events he worked alongside with V.V, Mao, and Luciano Bradley until they were dispatched separately later on, Lelouch found clues that the Joker was their hired contact-individual.
Later turned his attention to Zero, and Zero soon turned his insights upon him.
The Joker revealed secretly to Zero-that he knew his identity from the start.
Both clash many times about the points of social order and freedom vs chaos and anarchy. Zero's closest allies and friends along with other characters are deeply scarred by the Joker's actions when came across.
"YOZZAH! YOZZAH! LADIES AND GERMS! LETS HAVE A BIG LANDO LAUGH WELCOME FOR YOUR PAL...and his, NUMBRE-ZERO! HAHAHAHAHA! I AM DELIGHTED FOR YOU TO MAKE TO THIS FAR! THEN AGAIN, I ALWAYS KNEW THOSE OTHER LOSERS CAN'T PUT YOU OUT OF ACTION! AT LEAST, NOT LIKE I CAN! HAHAHAHAHAHAHA!"
The Joker kidnaps Euphemia and forces Lelouch/Zero to make a choice-barely Euphemia survives.
Apparently, battles between freedom-fighting Japan and regrouped Britannia forces still persists.
The Joker then uses Zero disguise to trick Suzaku, Euphemia, Cornelia, and Lelouch; he causes highly-classified fail-safe meltdown and a briefcase mobile that authorizes nuclear attacks within Britannian homeland while demanding money from Britannia Federal Reserve (foiled but it was a ploy).
The Joker then tricks Zero to order Euphemia to massacre Japan.
This eventually causes the crack of former friends and the royal family.
Suzaku (with vengeance) then almost captures Zero (shot off Lelouch's helmet) who was battling against the Joker who also disguises himself as Zero in certain base of operations-which leads suspicion of Zero being the Joker, and only able to capture the Joker, ironically what lead to his capture is that he tries to frame Zero.
Later tries to stab him in hand-to-hand combat. But accidentally stabbed himself-however not before insulting Nunnally which provokes Lelouch to cripple him...in front of a hidden camera-the Joker swallows what seems to be healing medicine-which "cure" his insanity, becoming a smart sane person.
The Joker was brought before Emperor Charles, later Suzaku was promoted to be part of the Knights of the Round.
The Joker then gave out his "business proposal" becoming very modest-due to the recent defeat.
Emperor Charles impressed by the proposal and directed Jeremiah to work with Suzaku and the Knights of the Round plus what-seems-to-be-reformatted Joker.
Only Lelouch, Kallen, C.C, and Suzaku only knows the truth, meanwhile the world hears from Britannia that Zero is "executed".
Helped out Suzaku on the Eastern front operational planning under alias "Jerry Napier"-a servant of the Empire. Basically he's like Darth Vader-type person.
He demonstrates and pulls off many high-quality plans to cripple Europa United to submission.
Zero/Lelouch on the other hand, pretends that he is indeed dead-but with Suzuku they keep an eye on him by trying to foil his extreme plans.
Slaughtered 114 people as a brief serial killer to terrorize minor areas of continent of Europe, used his persona of a professional criminal leader to confuse E.U's law enforcement.
During the established war between the Britannia Empire and E.U, Jerry became known ruthless but calm military leader by sending a navy fleet to terrorize the seas. creating mass causalities between 140-543 enemy fleets.
And then dreaded Operation-Telos final phase; hitting E.U everywhere at once. This eventually lead to conquering of E.U, and outwits Lelia and Akito.
Meet Shin Hyuga Shaing, and pretends to welcome his revealed envision of a chaotic world, a plan to cause open war between the 3 superpowers by nuking Pendragon with wZERO's Apollos' Chariot missiles to kill Charles.
Backstabs him with both him and Jean killed.
Thus Napier revealed his plan: after Zero announces that he's still alive and helping the Elevens and the Black Knights escape, he showed Japan of the brutality of Zero imposed on him.
Destroying the fact the Joker and Zero are same person anyways and threatened to sue Japan with its allies in the legal process to run them bankrupt because of that.
The (reformatted) Joker gathers remaining of his own henchmen and hired forces.
Meanwhile Schneizel decided to bring Zero down, however-the Joker soon confronts Zero with many hired criminals, and works inside with many judicial courts to "bring Zero to justice".
The Joker reminds Zero about killing "Prince Clover". He lead rewiring of Jeremiah becoming Two-Face but would later became a future ally of Zero.
However, with back-up tactics, Zero cornered the reformed Joker in nearby random toxic warehouse/"fun-house".
A two-boat hostages situation: one side of civilians, the other filled with random criminals. After a brief confrontation, the reformed Empire's "slave" fell into back the vat of chemicals-and returned fully as the Joker.
However, as he returned...he possesses the ability of being very cool and calm at day, and at night-very psychotic.
"So many you know-I went unsane...oh-uh...being reformed was dull...oh-but I'm coming BACK..."
He broadcasted to the appeal of his "fans" or his cult-like followers in Japan who admired his ruthless activities in the country, and told them to "purge" Japan's nighttime.
"In the darkness there are no rules. So tonight, for Area Eleven or should I say-Japan? Do what you want. Kill who you want. And when morning comes, you too will be reborn!"
Knocked out every Japan's electric powerhouses, and connections to the world. Sprayed "Joker Gas" through anonymous Knightframes. Riots and murder sprees rose beyond the measures. Britannian military inside stationed areas were overrun or joined in the insanity.
It was "No-Man's land".
Zero and the Black Knights were almost helpless to do anything (only to help the UFN to rescue the survivors).
Suzaku then proclaims to unleash a nuclear weapon at Tokyo (in attempt to stop the madness). However at daybreak-The Joker as calm as a cucumber announces that he already beat him to it...
By holding two familiar areas in Japan with an atomic bomb threat (Hiroshima and Nagasaki).
Additionally, Zero/Lelouch confronts the Joker who says that "he will instead of rebuilding free Japan by his own image". As many times in this universe, the Joker dares Lelouch to end him...supposedly in front of the media or everyone (Lelouch sees this ploy).
However, he finally selects his final endgame-after bombing the Ashford Academy, he uses Emperor Charles and alive Lelouch's mother to appear at Kamine Island/the Sword of Akasha.
Zero/Lelouch finally avenging of what he should have done-executing his immortal arrogant parents out of existence, the Joker soon was at mercy of both Suzaku and Lelouch. However, it was revealed that Lelouch used the Sword to rewire the Joker's mind, even though the Joker's insane mind is immune to the power of Code Geass-he became a potential harmless ally.
Codenamed: The Knight in Purple. He later helped to sanction Zero Requiem.
All of the criminal underworld across the world with his own personal remaining forces joined Lelouch's "invading forces", however all are destroyed as they are used as meat shields-and later the world and Japan is almost mainly free from organized crime and corruption.
He retires at an asylum because of the aftermath, the remnants of being the Joker inside of him crumbled almost due to seeing his "equal" die by Suzuku's hands who have taken on the mantle of Zero.
Or did it?
Z-
Z-Z
Z-Z-Z...Ze-
Zero...
The Joker returned from his catatonia state.
"Darling!"
