96 minus 135 equals negative 39

Back in New Domino City, Just on the outskirts of New Domino City were Jack, Crow, Leo and Luna, who were watching Yusei and Akiza from Jack's Duel Runner, in which they wondered what kind of twisted form of evil they would have to face, but knew Yusei and Akiza would prevail, in which they watched as their friends were taken to another one of the Champion Hunter's Death Zone Stadiums, where they could see a black cloaked figure just standing there as they waited for Yusei and Akiza to arrive, in which the figure then activated a Duel Disc that had been fastened to their right arm, indicating Yusei and Akiza would be Dueling for either Yugi, Jaden or Yuma's world.
"Let's Duel..." The cloaked figure then said in a dark, monotone and somewhat familiar voice.
"Who are you?" Yusei questioned, in which the figure didn't respond, but it was then another voice, filled of evil let out a wicked laugh, before they said. "He is no one. He exists only for the purpose of serving me."
It was then Yusei and Akiza watched in awe as a fiendish creature of darkness appeared beside the cloaked figure, which had a fully black right eye, a citrine coloured left and was covered in dark green markings.
"Dark Mist!" Yusei exclaimed, in which Dark Mist asked in a sinister tone. "So you know my name?"
"That's right." Akiza replied, before she told him. "Yuma told us all about you and how you manipulated him into Dueling for you."
It was then Dark Mist let out a small dark chuckle before he said. "And it looks like history will repeat itself."
However, before Yusei or Akiza could question what Dark Mist meant, the cloaked figure took off his hood, revealing them to be non other than Yuma.
"Yuma!" Yusei called out in concern, however, Yuma didn't respond, in which Yusei then demanded. "What have you done to Yuma!?"
"Nothing. This isn't the real Yuma, only a copy the Champion Hunter and I created out of the darkness the real Yuma tries to hide within his heart. And when I beat you, not only will I have my chance for revenge. But by the end I will have two Yuma pawns under my complete control."
"Not until you defeat us!" Yusei told Dark Mist.
"Very well. But since it's two on one I think it's only fair I start on double the Life Points." Dark Mist stated, before he asked in an amused tone. "Don't you agree Yuma?"
The Yuma copy then nodded his head and said in a distant tone. "I agree..."
"Fine." Yusei replied, before he and Akiza called out as they activated their Duel Discs. "Now, let's Duel!"
Starting Scores:
Yusei: 4000
Akiza: 4000
Dark Mist: 8000
"I'll go first." Yusei said, as he drew the sixth Card on the top of his Deck.
"I Summon Devotion Gardna in Attack Mode!" (1000/1000) Yusei announced as the Warrior Monster appeared before Yusei, before the ''King of Turbo Duels' then said. "Next, I send the top two Cards from the top of my Deck to the Graveyard so I can Special Summon Big Eater." (800/0)
"But I'm not done yet, as I Tune Devotion Gardna and Big Eater." Yusei announced as Big Eater then transformed into two green rings that surrounded Devotion Gardna, transforming Yusei's Monster to a transparent state.
As Yusei got out one of his Synchro Monsters from his Extra Deck, he chanted out in a strong voice. "So, from two come one, and from one will come great power! Watch as they merge their might and combine their courage! To Synchro Summon, Junk Warrior!" (2300/1300)
Yusei then said. "I'll play one Card face-down and end my Turn."
"My Turn now, so Draw my puppet." Dark Mist commanded, in which Dark Mist's Yuma did as he was told, before Dark Mist instructed, as Yuma did as he was told. "I Summon Kagetokage. (1100/1500) Next, I play two Cards face-down and with that, I end my Turn. So make your move Akiza."
"Gladly." Akiza replied, as she drew her sixth Card.
"I Summon Twilight Rose Knight." (1000/1000) Akiza announced, as she placed the Monster Card on her Duel Disc, before she declared. "And since Twilight Rose Knight was successfully Summoned, his special ability activates, which allows me to Summon any Plant Type Monster that is four stars or below from my hand. And the Monster I choose is Lord Poison." (1500/1000)
"I end my Turn by playing two Cards face-down. So it's your turn again Dark Mist." Akiza said, in which Dark Mist's pawn drew the top Card from his Deck, which made Dark Mist smile wickedly.
"I activate the Spell Card: Decrease." Dark Mist said, as puppet Yuma placed the Spell Card in the first Spell/Trap Card slot of his Duel Disc, in which Dark Mist then explained. "Now I can lower Kagetokage's Level by two." "
But I am far from done. Next, I activate the Spell Card: Drop Exchange. Now, by Discarding Achacha Archer and Kurivolt, I can Special Summon any Monster from my Hand which adds up to the combined Levels of the Monsters I Discarded and the Monster I choose is Gagaga Magician." (1500/1000) Dark Mist told Yusei and Akiza, as the chain wielding Spellcaster appeared beside the Level two Kagetokage, before he said. "And now Gagaga Magician's special ability activates, which means I can change his Level and I choose to treat him as a Level two Monster this Turn."
"I don't get it. Why is this Dark Mist guy lowering the Levels of his Monsters?" Leo questioned.
"I'm not sure, Leo. But I've got a bad feeling we're about to find out." Crow replied.
"And since I have yet to actually Summon this Turn, I Summon Gagaga Girl." (1000/800) And when I have Gagaga Magician is on the Field, Gagaga Girl's Level becomes the same, making her a Level two Monster." Dark Mist said, as Yuma placed the aforementioned Card on his Duel Disc.
"And now I Overlay these three level two Monsters in order to build the Overlay network and XZ Summon a copy of myself, Number 96: Dark Mist!"(100/100) Dark Mist exclaimed, as Kagetokage, Gagaga Magician and Gagaga Girl were each engulfed by a dark purple light, before the trails of darkness twisted around one another before a portal materialized on the floor where the trio of Monsters were combined, in which a dark blob came out of the ground, before it showed its true form, as it grew razor sharp claws, a fiendish tail, a pair of legs, a set of blazing fires for eyes and a mouth, with sharp fangs formed on its chest, which shocked Yusei and Akiza and their friends were just as shocked and confused by the hideous Monster.
It was then Dark Mist commanded. "Now, Dark Mist Attack Yusei's Junk Warrior!"
"That Dark Mist guy must be out of his mind. Junk Warrior has far more Attack power than his Monster." Jack commented back in New Domino City, but it was then Dark Mist announced in a dark tone. "I activate Dark Mist's ability, Shadow Gain! By using one Overlay unit Dark Mist can steal half of Junk Warrior's Attack Points in order to weaken your Monster and power mine up."
It was then Dark Mist's Monster opened it mouth and let out a shadowy fog, which struck Junk Warrior, lowering Yusei's Monster's Attack from 2300 to 1150 and raising Dark Mist's from 100 to 1250.
"Hold on Dark Mist, you just activated my Trap Card: Rose Curse! Now that Dark Mist's Attack has increased, you take damage equal to the difference between that monster's previous Attack and its current Attack." Akiza announced, in which a tornado of flame red roses swirled around Dark Mist, before they exploded, causing the dark creature to groan out as his Life Points decreased.
"You'll pay for that! But for now I'll just continue with my Attack on Yusei!" Dark Mist stated, before he commanded. "Go Dark Mist and strike with Whiplash Whirlwind!"
It was then Dark Mist's Monster's claws shot out and struck Junk Warrior, shattering the electric indigo armoured Warrior and inflicting 100 Points of damage to Yusei's Life Points, however, Yusei didn't seem fazed.
"I play the Trap: Miracle's Wake. Which allows me to bring back a Monster that was destroyed this Turn. So wake up Junk Warrior!" Yusei announced, before Junk Warrior arose from the Graveyard, in which Dark Mist commented in an arrogant tone. "I'm not sure what you're planning Yusei, but whatever it is won't work against me. Your move."
Current Scores:
Yusei: 3900
Akiza: 4000
Dark Mist: 6750
"You'll see." Yusei replied as he drew the top Card from his Deck and began his turn.
"I Summon Junk Synchron." (1300/500) Yusei said as the new Warrior appeared beside Junk Warrior, in which the 'King of Turbo Duels' then announced. "And now Junk Synchron, tune with Junk Warrior!"
Junk Synchron then transformed into three green rings that surrounded Junk Warrior, transforming the electric indigo armoured Warrior to a transparent state, in which Yusei got out his ace Card from his Extra Deck, he chanted out in a strong voice. "Out of two will come one, and out of one will come great cosmic might! Take flight, Stardust Dragon!"
A column of light then appeared where the two Junk Monsters were standing, and out of the light emerged the one and only, Stardust Dragon, which let out a loud roar as it appeared before Yusei.
"Go, Stardust Dragon! Attack with Cosmic Flare!" Yusei then called out, in which Stardust Dragon did as Yusei ordered and fired a blast of cosmic energy right at Dark Mist's Monster, but it was then Dark Mist said in a wicked tone. "Nice try Yusei, but I remove a second Overlay unit to active Shadow Gain!"
"No! That means Stardust Dragon's Attack will be halved and will be sent to the Graveyard just like Junk Warrior." Luna commented in a worried tone, before Leo said. "Luna, wait. Look at Yusei."
Doing as she was told, she could see Yusei had a serious look in his eyes, in which the 'King of Turbo Duels' then called out. "Not so fast Dark Mist. I active Stardust Dragon's ability, so by releasing my Dragon I can negate your Monster's Effect and Destroy it."
"Way to go Yusei!" Crow called out, even though he knew Yusei couldn't hear him, but he just couldn't help himself, however, Dark Mist then chuckled again before he said. "I told you whatever you were planning won't work against me, Yusei, and now I'll show you why. I play the Trap: Xyz Reflect!"
It was then Dark Mist's mindless Yuma activated the aforementioned Trap Card, before Dark Mist then explained. "When My Monster is targeted by an Effect that would Destroy it, I can Negate it, Destroy the Card that tried to Destroy me and inflict 800 Points of damage to you."
Stardust Dragon then let out a roar of pain, before it shattered into pieces, as Yusei let out a groan as the shards of Stardust Dragon fell down and struck him, inflicting him with 800 Points of damage.
"Yusei!" Akiza called out in concern, in which Yusei replied reassuringly. "Don't worry, Akiza, I'm fine."
"But at the rate you're Dueling, you won't be for long." Dark Mist replied in a dark and amused tone, in which Yusei told Dark Mist. "We'll see about that. I play one Card face-down and end my Turn."
Current Scores:
Yusei: 3100
Akiza: 4000
Dark Mist: 6750
"It's my move now and Dark Mist shall Attack Twilight Rose Knight! Let Akiza have it! Whiplash Whirlwind!" Dark Mist commanded, in which the Dark Mist copy launched its claws at Akiza and her Monsters, but it was then Yusei stated. "Sorry, but I play my Trap Card: Scrap-Iron Scarecrow!"
It was then the aforementioned Trap Card rose up, and emerging from the Card was the Scrap Iron Scarecrow, in which the scarecrow made from old wood, barbered wire, an old football helmet and a pair of damaged goggles appeared in front of Akiza's Monster and took the hit from Dark Mist's Monster's attack.
"In case you didn't know, Scrap Iron Scarecrow can take the damage inflicted by a Monster once per turn, before I can set it face down again and use its ability next turn." Yusei announced, as Scrap Iron Scarecrow retreated back into its Card, before the Card went back to face-down position.
"Thank you, Yusei." Akiza said happily, as she was glad the man she loved was looking out for her and knew that with the faith Yusei had for her she could defeat Dark Mist's Monster, in which she closed her eyes placed her hand on the top Card, in which Akiza then drew the Card, opened her eyes and smiled, as she had just the Cards in her hand she needed to assure victory against Dark Mist's Monster.
"From my hand I activate the Spell Card: Seed of Deception. Now I can Special Summon one Level two Plant Type Monster from my hand. And the Monster I choose is Evil Thorn." (100/300) Akiza said, as the Plant Monster appeared beside Twilight Rose Knight and Lord Poison.
"Next, I active Evil Thorn's ability. Now by sacrificing this Monster you take 300 points of Damage!" Akiza announced, in which the black bulb on Evil Thorn exploded, in which Dark Mist was bombarded by black coloured thorns.
"As one Evil Thorn is Destroyed, two take its place." Akiza told Dark Mist, in which two Evil Thorns appeared where the original once stood.
"Now I tune Twilight Rose Knight with Lord Poison!" Akiza called out, in which Twilight Rose Knight then transformed into four green rings that surrounded Lord Poison, transforming the Plant Monster to a transparent states.
As Akiza got out the Card her Deck was famous for from her Extra Deck, she chanted out in a strong voice, just like Yusei. "Let the spirit of the earth intertwine with the essence of the sky. I Synchro Summon the Black Rose Dragon!"
A column of Amethyst coloured light then appeared behind Akiza and out of the light, emerging through a swirl of rose petals was the Black Rose Dragon. (2400/1800)
Dark Mist then laughed before he stated arrogantly. "You're attempts to Destroy me is foolish. Whether you use Black Rose Dragon to Attack or not doesn't matter as I will use my final Overlay unit and raise Dark Mist's Attack power to 2450."
"That's where you're wrong." Akiza replied as a sly smile appeared on her face, which confused Dark Mist, before she asked in a sly tone. "Whoever said I was going to have Black Rose Dragon Attack?"
"I Summon Majestic Dragon." (0/0) Akiza said, in which Majestic Dragon appeared above Black Rose Dragon and the two Evil Thorns, in which Akiza then called out. "Now, Majestic Dragon tune with Black Rose Dragon and my two Evil Thorns!"
Majestic Dragon then grew larger as it bathed the two Evil Thorns and Black Rose Dragon in pink light, causing all three of Akiza's Monsters to become transparent, in which Akiza chanted out in a determined tone, as a new Synchro Monster card appeared on her duel disk. "Witness how a rose of beauty and destruction shall bloom and will rid all that dare to stand in my way. Come forth Majestic Rose Dragon!" (3650/2600)
And out of the light appeared a larger version of Black Rose Dragon that had four wings that were covered in dark red rose petals coming out of its sides while its tail had grown longer and was adorned with thorns and rose petals, which let out a loud roar at Dark Mist, before Akiza then exclaimed. "Now I active Majestic Rose Dragon's special ability!"
It was then Dark Mist watched in shock and confusion as four vines shot out from Majestic Rose Dragon's body and wrapped around his Monster's wrists and ankles, causing Dark Mist's copy to collapse to its knees, as its body went limp, in which Dark Mist questioned. "What's going on?"
"What's going on is when Majestic Rose Dragon is successfully Synchro Summoned I can select one monster on the Field and switch it to Defense mode. Then I can select any Monster in Defense mode, including the one I just shifted, switch it to Attack mode, reduce its Attack to zero and Negate all its Effects." Akiza replied, which shocked Dark Mist.
"Now, Majestic Rose Dragon attack with Black Rose Blast!" Akiza declared in a determined tone, and upon hearing the command, Majestic Rose Dragon fired a wave of dark red flames with black rose petals from its maw right at the Dark Mist copy, which was Destroyed and Dark Mist took a major hit to his Life Points.
Current Scores:
Yusei: 3100
Akiza: 4000
Dark Mist: 2800
Dark Mist let out a small groan of pain after all the Life Points he had just lost, but it was then all Yusei, Akiza, but most of all, Dark Mist were confused when Dark Mist's supposed mindless pawn began to chuckle darkly.
"And what're you laughing at?" Akiza questioned, in which Yuma. "What I'm laughing at is that now that Dark Mist's useless Monster has been Destroyed, I can take over this Duel."
"Hold on, I created you! You should serve me!" Dark Mist told his rebelling pawn.
"Well, we can't always get the things we want." Yuma replied in a dark and amused tone, before he held out his right hand and shocked Dark Mist as his hand was surrounded by dark energy and before he could do anything, his body broke a part and was absorbed into Yuma's hand, in which Yuma began to laugh wickedly as he could feel the dark power of Dark Mist flow through his body, before he unleashed a shock wave of dark energy, forcing Yusei and Akiza to hold their arms up to protect their faces.
And it was after the shockwave of darkness wore off, Yusei and Akiza were shocked to see Yuma now had the dark aura encircling him, as they could feel the evil power of Dark Mist surge through him.
"Now that's what I call power." Yuma stated, before he told Yusei and Akiza. "And from now on, I am no longer Yuma Tsukumo. I am Dark Yuma. And if you thought Dark mist was trouble then you're in for a real surprise."
It was then Dark Yuma held up a Spell Card, which had an image that looked similar to the Spell Cost Down, except two of the four Stars of were coloured black.
"I activate the Spell Card: Negative Stars. Now for one Turn any Monsters I Summon are treated as negative Level Monsters." Dark Yuma said, which confused Yusei, Akiza and their friends back in New Domino City.
"Negative Level Monsters?" Akiza questioned, before she asked. "What are you up to?"
"You'll see." Dark Yuma replied in a dark and sinister tone, before he placed a Monster Card on his Duel Disk and said. "I Summon Bull Blader in Attack Mode." (1600/1200)
"And since I now have a Warrior Type Monster on my side of the Field my Trap activates. Go, Copy Knight!" Dark Yuma said, as his aforementioned Trap activated, in which a second Bull Blader appeared beside the original.
"Now here's where the fun begins. I Overlay both my Bull Bladers to build the Overlay network and XZ Summon the Monster that will end this Duel and bring forth the end of New Domino City, Heartland City and anyone or anything that stands in my way!" Dark Yuma exclaimed as twin lights of dark purple light engulfed both Bull Bladers, before the trails of darkness twisted around one another as a portal materialized on the floor, in which Utopia arose from, however, Yusei and Akiza could see the Monster wasn't Yuma's Utopia, but an entirely different Monster, as the Monster had the same appearance as Utopia, except his white armor was jet black, the gold trimmings that adorned his body were dark crimson and on each blade had two different numbers, with -3 on the Monster's right blade and -9 on the other.
Dark Yuma then placed the Number Card on his Duel Disc and exclaimed. "Rise on up and show your fury Negative 39: Dystopia!" (2500/2000)
"Next, I use the Spell Card: Monster Reborn to bring back any Monster I choose from the Graveyard." Dark Yuma said, as he placed his Spell Card in his first Spell/Trap Card slot, in which Akiza questioned. "And you choose Dark Mist right?"
"Wrong. I don't need that weak freak to beat you." Dark Yuma replied, before he said. "The Monster I choose is Gagaga Magician."
"Now I Equip Wonder Wand which raises his Attack by 500 Points." (1500→2000) Dark Yuma announced, before he told Yusei and Akiza. "But I'm not done with Gagaga Magician as I use him to activate the Spell Card: Gagagabolt."
"And since I have a Monster with 'Gagaga' in its name, I can Destroy any Card on the Field." Dark Yuma told Yusei and Akiza, before he turned to Yusei and said. "And I choose your Scrap-Iron Scarecrow! So long you cheap scrap heap."
It was then a thunderous blast struck Scrap-Iron Scarecrow, sending the Trap to the Graveyard, but Dark Yuma was far from finished. "And now to deal some serious damage. By removing one Overlay unit Dystopia gains 500 Attack for every Level the Monster I removed. And since I removed a Level four Monster, Dystopia gains 2000 Attack Points!" (2500→4500)
"And thanks to Dystopia's ability I can use its second Overlay unit in the same Turn. Giving him another power boost!" Dark Yuma told Yusei and Akiza, which shocked them as Dystopia's Attack power increased again. (4500→6500)"
"Now, Dystopia Attack Majestic Rose Dragon with Shadow Blade Slice!" Dark Yuma commanded, in which Dystopia pulled out both of his blades, before the negative version of the real Yuma's favourite Monster struck the Majestic Rose Dragon, which let out a roar of pain, before it shattered into pieces and was Destroyed, taking a ton of Akiza's Life Points with the Attack. (6000-3650=2350)
"Now it's your turn Gagaga Magician. Attack Akiza directly!" Dark Yuma commanded, in which the Dark Spellcaster charged at Akiza.
However, it was then Akiza revealed her final Trap Card. I activate Wicked Rebirth. Now, by paying 800 Life Points I can select one Synchro Monster from your Graveyard, and Special Summon it to the owner's Field. And the Monster I choose is Stardust Dragon!" Akiza announced, as Stardust Dragon rose before Yusei, just as Gagaga Magician struck Akiza down.
"Akiza!" Yusei called out in concern, but was relieved as the woman he loved managed to get to her feet, before he turned back to Dark Yuma, as a burning termination filled his eyes and very soul.

'Akiza, you risked your last Turn to give me a chance to win.' Yusei thought to himself as he stared at the top Card of his Deck and then thought to himself. "And I won't let you down."
"My Turn!" Yusei yelled out, as he drew his Card.
"I Summon Majestic Dragon." Yusei said, as the pink colored Dragon appeared beside Stardust Dragon, but it was then Yusei announced. "And now the Effect of the Turbo Booster (0/0) in my hand activates, which allows me to Summon it alongside Majestic Dragon. Now, Majestic Dragon tune with Stardust Dragon and Turbo Booster!"
Majestic Dragon then grew larger as it bathed the two Monsters in pink light, causing them both to become transparent, in which Yusei chanted out in a determined tone, as a familiar Synchro Monster card appeared on his duel disk. "I harness all the power of the stars, I channel all the might of the dragons, I Synchro Summon the Majestic Star Dragon!" (3800/3000)
"Nice try, Yusei. But your Majestic Star Dragon is no match for my Monster and there's no Card in your Deck you can beat me with."
"You're right." Yusei admitted, before he told Dark Yuma in a sly tone, which confused the dark version of the Number Hunter. "But there's one in your Deck."
"I activate the Spell Card: Monster Reborn and use it to bring back Dark Mist!" Yusei exclaimed, as Dark Yuma watched, as a horrified expression appeared on his face as Number 96: Dark Mist rose from the Graveyard beside Majestic Star Dragon.
"Now, Dark Mist use Shadow Gain then Destroy Dystopia with Whiplash Whirlwind!" Yusei commanded, in which Dark Mist used its final Overlay unit and unleashed another wave of shadowy fog, which struck Dystopia, lowering Dark Yuma's Monster's Attack from 6000 to 3000 and raising Dark Mist's from 100 to 3100, before Dark Mist's claws tore into and Destroyed Dystopia, leaving Dark Yuma open to a finishing blow.
"Now it's your time Majestic Star Dragon." Yusei said, before he commanded. "Attack with Star Shine Shred!"
"No, this cannot be. I... I lost..." Dark Yuma said in disbelief, before Majestic Star Dragon struck him in the chest, ending the Duel and his existence, as Dark Yuma faded into darkness.
Ending Scores:
Yusei: 3100
Akiza: 0
Dark Yuma: 0
Back in New Domino City, Crow, Jack, Leo and Luna were cheering for Yusei and Akiza, proud of what they had just witnessed, but it was then the heroic pair were both enveloped by dark red energy and taken away.
