The once quirkless Midoriya Izuku (Deku) who fought an entire life to be a hero, and always bullied by own closer friend Bakugou Katsuki, was not even expect, even for the Deku one, once he finish the middle school, the key to unlock their powers would end in a unimaginable disaster.
The Hero City, in a single night, suffer the most apocalyptic disaster, surpassing the damage make by all the villains continuous raids. Several buildings reduced to ashes, incommensurable number of burning corpses. Even in the apex, almost a million people tries to flee of this blazing inferno.
Even the regular army are totally powerless, except for one or two heroic strike, against the giant flying dark dragon that rages, blasting his fire breath against the buildings, and even so, just above the two massive black-reddish wings with over 200 meters of span, some smaller dragons flies around the ruined city, making more precise strikes.
The U.A. academia still survive the onslaught, even several students tries to hide on the subterranean bunkers, some of them maintains on the ground level to report the current situation.
The famous Bakugou, now a second-year student of this highly prestige hero academia, still face the horror of this disaster, "What… On the Hell is this ?!"
"Mister Katsuki...", one of top hero teachers blocks their way, "Please hide on your bunker."
"It is a real apocalypse, and no hero can stand against this ?!", Katsuki says angered.
"Mister… If even the army was almost powerless against that Quirk..."
"A Quirk ?! Such monstrous abhorrent thing ?! This is an human with a quirk ?!", and later Katsuki continues after calm down a little, "And you said the army was not standing against this thing ?!"
The blond boy receives a slap against his face by some adult, while a strange light flash echoes on sky, and explodes right below the main dragon body. Once the dust settles, a grudge young boy with black wings sat just below the horrific vision, and he disdains while screaming so loud, that even on U.A. site could hear, "I jump to this Dimension, and I just saw the mother of all Demons ?!"
Everyone was shocked, but the giant dragon also disintegrates, and the person who hold on the former dragon chest, descents and settles a few meters against the strange new challenger.
Bakugou runs off to the site, ignoring the yells from their teachers, and in a couple of minutes hides against a ruined wall, just about 100 meters to the fated two mysterious boys encounter.
"Good evening", says the challenger, "I'm the Demon Duelist Zarc!", ending with a smirk.
The blond boy hears the first boy's name, and bumbles, "What a stupid name...", but once turn his head to check the second identity, it fall on shock, "De...ku ?!", feeling a dried throat, and a whirlpool of mixed emotions. A split second later, he was pushed by some unknown phenomena, dragging against his will and pushed against the concrete floor, causing several injuries.
"Deku ?!", and even so, Bakugou maintain conscious, but observe that the now taller green haired boy, was devoid of any emotions. It was about 18 months ago, since it mysteriously disappear just after the middle school, once his application submit to U.A. has rejected mainly due to the lack of an innate quirk. Bakugou notices that his outfit was black, with some gray strips along the major articulations. A strange device, that resemble a card game appliance was fixed on his right wrist. Bakugou remember that some his middle school friends likes to play Duel Monsters, and probably it was one of this gaming devices.
The green hair boy turn a little his head, and glares against his former bully, while speaks like a Parthenon ancient deity, "Why some insects tries to spy on us ?"
Bakugou reacts when hears the sentence, "Insects?! Damn, Quirckless Deku! You can explain...", and his body suffer a sudden acceleration while flies a few meters, followed by a strong push against the crater on the concrete slab.
"Quirkless ?", Deku speaks while saw the former friend bleeding from the head, "Well, I also thought that was born without a native quirk… However, your bullying was after all the key to activate my real, innate quirk..."
"A delayed quirk ?!", even to Bakugou, it is still unbelievable that someone takes about 16 lifetime years to his quirk to manifest, since normally it takes a few years.
" Supreme Demon King Dragon Deku!", the boy yells, while appoint his index finger straight to the sky, "That's my Quirk!"
" What is that ?!", says Bakugou.
" So it's your main card name also, right ?!", says Zarc, while Deku nods positively.
" My Quirk are beyond the ones from inferior humans, making the Heroes and Villains so pathetic", and also activates the Duel Disc, since Zarc was make the same, "In fact, my Quirk was beyond the God itself!"
" What's happened… to you ?", Bakugou faints.
" I never forgot this day!", Deku screams with greater maleficence, "After been over-bullied in a single day, once my future was ruined, or I thought it was, more than I receive in an entire year!", and makes a fake pledge of piety, just to burst in laughs, "However, once I run over the streets, my body explodes, and my dragon form was born!", and also makes a strange dark toned smirk, "I was also throed, my some magic means, to the Duel Monster Dimension filled with monsters, and an pleasant plethora of sweet horrors and yummy nightmares!"
The blond hero recovers a little conscience, just to listen, with greater horror, the own former friend explanation.
"And when you return here ?!", asks Zarc.
"On that Ultimate Sweet Nightmare Dimension, I could mastered my Quirk, and then I could jump to this dimension…"
"And then..."
"I summon my real quirk form, and destroy this city! Easy as it gets...", Deku ends his explanation.
"I don't have a thing called Quirk, but using my advanced technology I destroy my home Original Dimension, and split it into four!"
"Can I try? Can I try ?", asks Deku.
"What the hell are talking about ?! Splitting dimensions ?!", asks a stunned and shocked Bakugou.
"Even I can't say the details, since it was done by my Supreme King Dragon Zarc, and I forgot what happens next, except the fact the world was splitted!"
"Now is time to Duel!", says Deku.
"Right !", Zarc accepts the challenge.
"Duel!"
Their Duel Discs was activated, and a strange force field covers the entire city.
Turn 1 (Deku): LP 8000, 5 Cards on Hand
"I begin first", says the former hero dreamer, "I summon from my hand, the Continuous Magic Card: Forbidden Pact with Vampire Lord".
"Oh ?!"
" This card enables to send the rest of my hand to the Graveyard,while I draw the same amount of cards."
"Very interesting...", and smiles, "It is a full Summon Combo ?!"
"And set the following Pendulum Cards: Demonic Gate Hell, Scale 0, and the Demonic Gate Hades, Scale 13, setting the Pendulum Scale on my Pendulum Zones!"
"Demonic Gate Hades and Hell ?!", Bakugou was stunning, "He don't have such cards !"
"Sinful humans!", Deku begins the summon mantra, "Repent and pray to the Underworld Lord!", while laughing maleficent, "My unlimited hatred shall given to the absolute punishment of Mankind!", even Bakugou was not witness so great unanimity spoken against him, or anyone, "Be my portal of damnation, and release my minions!"
"It begins!", Zarc smirks, while the Pendulum Portal opens.
"Pendulum Summon!", screams Deku, "Appear, my two Level 7, Demon King Necromancers!", the two medieval black dragons appears, and roars, while emit a giant aura pressure that everyone could not react, expect by feeling an unbelievable fear.
"Two equal levels. It means...", Zarc smiles!
"I tribute both Necromancers to build an Overlay Network! Xyz Summon!", and yells, "My powerful ally of Death! Descend upon the doomed land, and bring the real order to earth!", and declares, "Rank 7! Deathly Scythes Xyz Dragon!"
"A Xyz Dragon subtype like me!"
"Now I use the main effect of my Necromancers while resting on my Graveyard...", the malefic Deku smile even affects Bakugou, "I can Special Summon from my Graveyard, any monster which level is less than the Necromancer itself!", and concludes, "So. I return the Level 5, Tuner Monster, Demon Apprentice, and the Level 6, Sinful Darkness Dragon".
"And now it is ?!", Zarc was also smiling.
"By own Darkness Dragon summon effect, I can Special Summon from my Graveyard, a Level 4 monster or less, and this will be the Level 3, Rotten Witch"
"Then I synchronize Rotten Witch with the Demon Apprentice...", and Deku screams like a demoniacal clown, "Dreadnought armoured demon… tune with the heresy... And bring the messengers of Death to your realm! ", and concludes with, "Synchro Summon! Level 8, Cursed Reaper Synchro Dragon!"
"Nice name, I like it!", says Zarc.
"Finally, I banish both my Necromancers form the Graveyard…", and chants, "Kings of the Dead… Servants of the Sins… Forgot your nuisances, and reunite together!... Fusion Summon!", and make Deku smiling like an insane bloodthirsty tyrant, "Level 9, Malefic Judgment Fusion Dragon!"
"And last the Pendulum Dragon? Right ?!"
"Maybe...", while Deku announces, "When I control a Fusion, Synchro and Xyz monster, by tributing Sinful Darkness Dragon, this card can be Special Summoned from my Graveyard!", and speak it, "Arise! Ritual Magic Card, Dean of Darkness!"
"You also use Ritual Summon ?!", Zarc notices it's own missing skill.
"Taking the current Level and Rank of my monsters summoned from the Extra Deck, and I add up to two monsters which Level should be 7 or 8...", but adds, "And I can use the banned Necromancers as Ritual Tributes!"
"Oh… oh!"
"For the fragile, and the powerless, take our redemption, and flee into the sea of despair where the hope are a meaningless dream!", and speaks loudly, "Ritual Summon! Appear here! Level 7! Raging Despair Ritual Dragon!"
"Unbelievable!", Zarc in fact rarely saw a Ritual Summon.
"And the former Magic Ritual Card is treated as Tribute to do an Advance Pendulum Summon!", and make it, "So I summon the second monster from my hand…", and chants, "From the dashed hopes of weaklings, to the hypocrisy of strongish… Make them to the burning sacrifice!...", and his body emits a giant energetic pulse that destroys more ruins on neighborhood, "Reborn here! Level 8! Burning Sorrow Pendulum Dragon!"
"Wonderful! Pendulum, Ritual, Fusion, Synchro and Xyz Summons on your first turn!"
"Turn End!", and Deku passes the turn to Zarc.
However Bakugou was totally bewilderment, "How it is possible ?!". In fact never thought that your childhood friend, even it was the bully one, reveal openly such great hatred not only against him, but also to the entire mankind!
"Deku… I...", Bakugou tries to speak, but some demons appears around him to try rip apart. All Might appears swiftly, and tries to clean the path to rescue Bakugou, and even so receives a massive amount of damage when it was tries to fight an entire army of demons and venom ghosts, that the Deku quirk makes it summon.
"What kind of monster it is that "human" ?!", even All Might thinks that Deku was beyond all standards, "Which creature could give the birth of the Son of Apocalypse ?!"
"All… Might...", Deku faint again, "It is all my fault...".
All Might runs and narrowly escapes the main path to the underground bunker, but a debris blocks the entrance, and he must clean first. Bakugou recovers his senses a little, and both tries to listen the second turn of this dangerous Yu-Gi-Oh Duel.
Turn 2 (Zarc): LP 8000, 6 Cards on Hand
"The scum was cleaned away… It's my turn!… Draw!", says Zarc.
"Now I should stay alert..."
"From my hand I set the Supreme King Gate Zero, Scale 0 and the Supreme King Gate Infinity. Scale 13, on my Pendulum Zones!"
"You have also a wide Scale 0 to 13 range ?!"
"It this current setup, I can make a Pendulum Summon of any Level 1 to 12 monster!", and Zarc make do so, "Pendulum Summon! Arise the absolute ruler servants: two Supreme King Servants Darkwurm, both Level 4...", and a third monster arise…, "And the Level 7…", and speaks the chanting summon, " Arise the beautiful dragon with heterochromatic eyes...

"Oh! Burning Sorrow, versus Odd-Eyes!", Deku notices the mutual dragon desride for territory domination, even both have the same ATK, which is 2500.
"And when I have two Level 4 monsters, I can activate this Quick-Magic Card… Absolute Fusion!"
"Wow! A freaking Fusion card ?!"
"With this card, I can tribute two Level 4 monsters to do a Fusion Summon, treating them as Level 5 tributes, a Synchro Summon, where one of tributes will drop a Level to be treated as a tuner, and the original levels to build an Overlay Network, to do a Xyz Summon!"
"It comes! It comes!", Deku don't hide the malicious excitement.
"Sacrificing the ruler servants, it will give birth of a new beautiful nightmare, and reborn the venomous dragon with beautiful petals, and an assassin instinct!", and declare, "Fusion Summon! Level 8… Starving Venom Fusion Dragon!"
"My Malefic Judgment welcomes your rival and partner!", even it was 3000 ATK versus 2800 ATK.
"Now one of my servants will decrease to be a Level 3 tuner monster!", and Zarc speels his mantra, "My two servants… Please tune together to bring the whirlpool that slash his enemies by the speed of light!", and concludes, "Synchro Summon! Level 7… Clear Wing Synchro Dragon!"
"And Cursed Reaper gives an "hello"!", and both have 2500 ATK.
"And finally, the last special summon!", says Zarc, "I overlay both servants to bring the last dragon...", and announces, "Beware the fouls that fought against the tyrants… Unleash your fangs against the oppressors, and give birth to your rebellion!", while yells, "Xyz Summon!

"It's Death Scythes against Dark Rebellion, even it have the same power!", both have 2500 ATK.
"However, your Raging Despair was lonely", even it was 4000 ATK, the strongest Deku he have.
Now the long awaited Battle Phase begins, "Dark Rebellion!", speaks Zarc, I detach all Overlay Units to reduce the Raging Despair own attack, which will drop to 1000 ATK, and increase the Dark Rebellion to 5500 ATK, "Treason Discharge!"
"As expected!"
"Now I use the Starving Venom effect! I will stole the Cursed Reaper special effect that reduces all Special Summoned monsters by half, and applies against you!", and several Deku's monsters lose several ATK.
"Nuts! Now my Ritual, Pendulum, Fusion, Synchro and Xyz monsters drops to 500, 1250, 1500, 1250 and 1250 ATK by the same order!".
"With this, the original ATK are added to Starving Venom Fusion Dragon!", giving 17300 ATK, "And now it's over! Starving Venom Fusion Dragon! Attack Raging Despair Ritual Dragon!"
"Very disdainful, Zarc!", screams Deku, "I activate the Pendulum Effect of Hades!"
"Now it comes to real!"
"When a monster declares an attack against other that could give me defeat, I use the Hades effect to destroy the two monsters!", and the Deku's Ritual and Zarc's Fusion dragon was destroyed!
"Self-destruction, he ?!"
"And both of us will receive 1000 damage for each monster destroyed!", screams Deku, insanely.
"Fool! I use the Pendulum Effect of Zero, to reduce any damage from any source to zero, and then the Pendulum Effect of Infinity will increase my LP to the same amount", and Zarc LP increases to 10000 LP!
A little below the carnage, on the ground, All Might listens the Duel progress, while mumbles to himself, "This Deku are totally insane."
Bakugou still catches the last Zarc movement, before faint again, "What… was… that? A card effect that convert damage to life… ?!"
"Argh! Your Pendulum Monsters", screams Deku, while tastes the blood spilled by the debris caused by the last monster destruction, and saw his life drops to LP 6000, "And by the Hell Pendulum Effect, I can draw two cards when I receive damage from any source!"
"Then… I will attack your Burning Sorrow with my Odd-Eyes!", and explains, "I since your monster is greater than Level 5, during the Damage Step, the damage is doubled!", while yells, "Reaction Force!"
"And I draw another two cards...", even their life drops to 3500 LP.
"And finally, I use the Dark Rebellion to destroy Deathly Scythes!", and destroy with, "Lightning Strike Disobey!", that could won this duel.
However, while Deku receive the attack, he reacts, "When Deathly Scythes are destroyed with Overlay Units attached to it, and my life drops to zero, I can detach one to destroy the adversary monster", making the destruction of Dark Rebellion, "while detach the second one to add their original ATK to my LP", restoring his life to LP 2500, and draws another two cards due to Hell Pendulum Effect.
"Another of your dirty tricks!", but advance with the last resource, "Clear Wing Synchro Dragon, attack Burning Sorrow Pendulum Dragon!", destroying them, while drops Deku's life to 1250 LP.
"And now have 8 cards on my hand!"
"Turn End!", said Zarc, a little unpleasant.
All Might almost manage to clear the debris that block the last meters to the safe bunker, while notice that Bakugou bleeding was worst that he thought, "He need medical assistance quickly."
Turn 3 (Deku), LP 1250, 9 Cards on Hand
"It's my real first turn!", Deku changes his tone to imitate a raging god, "Draw!"
"Now it is the real revenge!"
"I set 5 reversed cards on my Trap and Magic Zones!", and then adds after a little pause, "I destroy the Cursed Reaper Synchro Dragon to destroy all of your monsters you control", and Zarc makes a disdain smirk while lost Clear Wing and Odd-Eyes.
"And the last four cards on your hand ?!"
"Using the current Pendulum Scales… I make a Pendulum Summon of this monster", and appear quickly, "Level 12… Dark Summoner of Doomed Souls!", and maintains three cards on this hand.
"It's magic or some special monsters ?!"
"When I have one Ritual, Pendulum, Fusion, Synchro and Xyz monster on my Graveyard, I can tribute the Dark Summoner to activate this effect..."
"One a minute… It could be ?!", even Zarc was astonish.
"Five Sacred Dragons of Demon World, unite their revenge and hatred against their enemies!", Deku begins to release a black aura that start to tremble the entire city, sparkling dark-reddish lightning that starts to ignite fires, and demolishes ruined buildings and expressways, "Unite with me..."
"It's the same thing!", while Zarc prepares to counter-attack.
"Unification Summon!", and Deku fuses with the black aura that reshapes into a black dragon, "Arise the real nightmare of heretics… Reborn the ultimate dragon that shall give eternal damnation and horror of every dimension!", and yells so loudly that was audible even to several kilometers, "Level 13! Supreme Demon King Dragon Deku!"
"And just reborn!"
"This monster is equally a Scale 13 Pendulum Monster, a Fusion, Ritual, Synchro with Level 13, and also a Rank 13 Xyz Monster!", with 100000 ATK.
Meanwhile, just when All Might, and Bakugou recovers momentarily, to witness the real quirk form of Deku, just became astonishing, "Deku… What are you ?!", and flees to the underground.
"This monster cannot attack on the same turn it was summoned, but can Special Summon those three Level 7 monsters", and make do so, "Dragon Demon Knights"
"And you end your turn...", speaks Zarc.

"And you will summon your supreme dragon too."
"From my Graveyard I ban Dark Rebellion Xyz Dragon, Clear Wing Synchro Dragon, Starve Venom Fusion Dragon, Odd Eyes Pendulum Dragon… And become my recipe..."
"A reunion with four dragons..."
"Supreme dragon that rule beyond the four dimensions! Come here to unleash your powers!", and screams while integrate the supreme dragon, "Unification Summon! Release my Level 12 ultimate monster", with a solemn proclamation, "Supreme King Dragon Zarc!", even with only 4000 ATK.
"Bravo! My real rival was summoned your supreme dragon!", Deku claps his handsm while much part of his body was fused with the dragon.
"When Supreme King Dragon Zarc was successfully summoned, all of your monsters you control are destroyed, and you will receive damage equal to their ATK combined!"
"Really ?!", the Demon Knights are destroyed, "But my Dragon cannot be destroyed by anything… And also when I receive an attack, while I control another monster, that cause my life drops to zero, I can add my Dragon ATK to my life..."
"Impossible ?!", Zarc was dumbfound, "Now you have 100000 LP ?!"
"It's now Turn End, right ?!", Deku face change to a malefic smile, and a dark laugh.
The Duel on Hero City, or what rest of, shall continue!
