I added a bit of the intro to Yusei here, hope it works

Don't own Yugioh or Harry Potter

0000

Duelist, young and old, professional and amateur alike. it's the moment you've been waiting for...

Currently huddled around a computer watching the duel were three men, one known as Tank, another as Nervin, and the final as Blitz.

I hate the guy...but he has done well for himself." Blitz grumbled as Jack came to a standstill.

"to think we'd all be in that stadium if he hadn't screwed us over." Tank sighed.

We see a red motorcycle in an abandoned subway tunnel.

000

A lone crimson duel runner was running through the abandoned subway tunnel, on it was one Yusei Fudo, currently testing out his latest model of duel runner, almost got it. He frowned as the motor blew out. Looking up in sorrow he sighed, I'm coming for you, Jack. He promised as he began pushing his runner home.

000

Yusei huffed as he parked his duel runner, his friends were watching a Jack Atlas duel, tuning it out he attached his duel runner to the computer.

Yusei revved the engine, which sounded weak to him, catching his friends by surprise, "Oh, uh, hey, Yusei," Blitz said nervously as Nervin Hurridly turned off the stream.

"Sorry about that," Tank said, "you know the computer only works here.

"Jack was amazing as always," said Nervin.

"how tough was his opponent?" he asked Idly.

"decent duelist...but Jack completely trashed him," Blitz said, mildly impressed that Yusei wasn't mad.

"He's gonna get bored soon..." Yusei said idly, knowing that if he got too bored Jack would come for one of them, be it him, Harry, or even Qrow.

"howd the test run go?" Tank asked.

"Duh, Tank, does it look like it worked?" Blitz sighed and rolled his eyes.

"right...Although, hey, your other runner looked great on TV," Tank said

Blitz growled and slapped the back of Tank's head, "read the mood dude!"

"Yusei!" a voice sounded, stopping everyone's conversation, "hey, Yusei," said the voice.

"In here, Rally" Blitz called.

"oh! Everyones here. Yusei can you use this for your duel runner?" he held out a Skylon- 30 acceleration chip.

"That's a Skylon," said Nervin impressed.

"It looks like it's never been used," said, Blitz as he grabbed Rally's wrist to get a closer look, "Don't tell me ya stole this"

"It was just laying on the ground in broad daylight," said Rally.

The three older men shared a look.

"you know if that's stolen we could all get arrested." Tank said.

"they'd mark us all just like you Rally." Nervin tapped the yellow mark on Rally's cheek, "you know those things allow security to track you at all times."

"Enough guys." Yusei said as he held out his hand, "ill use it. This is just what I needed." he said as he swapped the old cracked one out.

"Will it make you faster?" Asked Rally.

Yusei nodded as he inserted the new chip into his runner.

"you're sure about this Yus? You could be thrown into the facility." Blitz said.

A beep sounded and Yusei grinned then revved the engine, sounding much stronger than before.

All three men were stunned as the sound echoed down the tunnel, "take it out for a spin!" Rally said excitedly.

Then light flooded the dark tunnel.

"It's sector security!" Nervin yelled.

Identification number Awx-86007 Rally Dawson, you are in possession of stolen property said a man over P.A.

Rally grumbled a little as everyone turned towards him, "alright fine...I took it from the factory."

"Why you!" Blitz raised a fist but stopped as soon as Yusei placed a hand on his chest.

"It's gonna be alright," said Yusei as he turned and hopped into his runner, typing in a few keys, "I jammed Rally's marker. You guys go out the east exit, ill go out the west exit. Head over to Harry's, his place is completely unknown to security."

You heard the man," said Blitz, "Rally, you know the best way. You want to pay us back, get us there without being caught."

"right. But the fastest way is through the southern exit, follow me," he said.

Yusei burst out of the tunnel and almost immediately was chased by security.

Man, I didn't think they'd be on me this quick.

You on the runner, pullover!

Turning into an old vacant lot Yusei retracted the visor on his helmet and the officer got off his runner.

"no marker...so you're the decoy huh. You know you're going to the facility for aiding a fugitive." Trudge said with a smirk.

"only if you beat me in a duel."

"oh? Satellite trash challenging me to a duel...It's too bad the rules say you satellites can't carry cards," Trudge smirked.

Yusei held up his deck, "if I win you give up the chase."

Trudge smirked, "get going. I'll take care of this."

"But sir!"

"go! Do you think id lose to satellite trash? I'll take the heat."

000

Harry frowned at the proximity ward went off, "what's got them in such a rush?"

Opening the door his friends ran through out of breath, "Harry! You gotta jam my marker...I got caught stealing."

"oh, Rally..." Harry sighed and shook his head, "where's Yusei?"

"he took his duel runner to attract security," Nervin said, looking amazed at how clean Harry's house was.

"always down for a duel." Harry shook his head, "well, make yourself at home. Security can't find this place."

"you don't seem worried." Tanks said, the question not needing to be asked.

"Yusei knows how to deal with Security. He shouldn't have a problem getting rid of them. Hungry?"

"is that a trick question?" they all said at the same time.

000

The next day

The sun was setting, casting beautiful hues and shades of red, purple, pink, orange, and yellow across the sky. The ocean was calm and sparkled like glittering jewels when shone on with light. In the distance, Satellite shined as the sun's final rays reflected off the metal patch jobs the people of satellite had put up.

Viewing all of this was Jack Atlas. He stared out of the glass walls of his skyscraper penthouse. He was wearing a black, sleeveless shirt that showed off what looked like a red tattoo on his arm. He had no idea where it had come from, just that it had been with him for as long as he could remember.

That lead his thoughts to another person who had had a red tattoo on his arm for as long as he could remember as well. 'Harry.' He thought. He glanced at the coffee table behind him and looked at his deck. A silver card laying next to his own card, bringing Yusei to his mind.

'I wonder if Yusei still misses you Stardust?'

"Quite the view isn't it Jack? Still thinking of your days in the Satellite?" A voice said from behind him.

He didn't need to turn around to know who it was. "Goodwin," he paused, "I'm done thinking about that dump."

"Really?" Goodwin questioned. "Even certain… individuals?"

Unwillingly, an image of a black and red-haired teen with a blue dragon standing behind him flashed through his mind. He took in a deep breath and let the image dissipate as he exhaled, though it was difficult. He and Harry had much the same dueling style, and Harry had a passion for dragons beyond even him.

"Yes."

"That's good, Jack because dwelling in the past can sometimes cost you your future. And we've all worked too hard to let that happen." Goodwin said.

"Hmph," Jack finally turned to face Goodwin, "You don't have to worry about me dwelling in the past. If I had it my way, the Satellite would've been destroyed years ago!"

"I understand how you feel Jack," Goodwin began in a condensing tone, "But the Satellite plays an important role in our society. They exist so we can prosper." Goodwin clapped his hands together, "But you already know that don't you Jack? Now let's leave the past in the past and move on!"

Jack grunted and couldn't help but feel something was about to change. He looked down at his tattoo and then stared out the glass walls towards Satellite again.But what if my past comes looking for me?

000

Putting down his screwdriver Harry sighed as his duel runner went off from someone calling him. Pressing a button he frowned, "Rally? What's up?"

"Hey, Harry!" He grinned, "I need your help...Tank and the others ran into a bully and got beaten up, and my medical expertise is putting a bandage on it."

Harry frowned but nodded, you would think that since they all had to live in this garbage people would look out for one another, but that just wasn't the case. He nodded, "alright. I'm on my way."

As Harry drove through the ancient subway that Yusei and his friends had called home he frowned at the duel that was just ending, the guy Yusei was dueling was using an insect deck...but the guy must not duel much because as he pulled up the guy had just lost the duel due to his retribution of the ant lion card.

Yusei Fudo turned back towards the duel runner that revved down, as his brother in all but blood stood up from a beautiful duel runner, it was similar in design to his, but instead of the loop around the top, he had shaped the whole frame to look like he was riding on actual blue eyes white dragon.

Harry had changed his outfit since he had last seen him, he wore a black sleeveless tee shirt like him, but he had the head of the blue eyes on the chest, he wore blue Jean's with several belts hanging off at the waist, and a jacket hanging off his shoulders, but unlike Yusei did Harry had his attached to his shirt and he wore it like a Cape, the blue eyes white dragon etched into the back, and the sleeves had the claws, and the dual-layered hairstyle Martha had given him years ago seemed to glow now in all the red spots.

"Harry. What's up?"

"Rally called me in. Said you needed a medic."

"That is so cool Harry! How'd you get all these parts?!"

Harry laughed at the young man he had mistaken for a female the first time they met, "I worked 'em off. An old contact of mine smuggled several pieces out of Domino city. Took me forever till he said were square." He popped the stand and took a look at his friends, "mostly bruises..." he pulled out a vial of a thick green substance and began to dab it on Blitz's cheek as the guy winced in both pain and the smell of the stuff.

Rally grinned as he saw both the paste and the bruise fade, "that is so cool. I wish I could do that!"

Harry just grinned sadly, "stuff like this was the last gift I had from my parents...I'd like to think it would make them proud that I could use it on my friends."

Yusei smiled at his brother, "Harry, how fast have you gotten your duel runner?"

Harry looked to his friend, "I maxed it out last week. Only just finished paying off the skyline chip that Blister smuggled for me. what's up?"

Yusei booted up a computer, "we have a plan to get to New Domino tonight." Harry watched the image on the device, a hatch that opened once a month for Maintenance. "Problem is, ever since I beat a sector security officer in a duel last time, the security never travel around alone. If I have to go up against more than one sector security I may not make it."

"I'm in man. When do we leave?"

"The hatch opens at midnight, so be ready by 11:30."

Harry grinned and clapped his friend on the shoulder. "I'll be back by then, I've got to go pack up first."

000

Trudge was staring at the deck he had just been given, "sir...what's with the new deck?"

The commander grunted, "this deck is a special gift to you from Jack Atlas himself. He's noticed the illegal use of duel runners lately and recommended that I form a task force for that problem. I want you on that team, but I felt you needed an...extra boost since losing to that satellite. Don't make me regret this."

Trudge gulped and nodded, "yes sir." Turning to central, "let me know when the signal in that duel runner."

000

As Harry started up his duel runner and put on his helmet, it was in the shape of blue eyes and the teeth descended and acted as a visor against the wind, Rally ran up to Yusei. "I almost forgot! Here." He handed the card to Yusei and smiled sadly at Harry. "Sorry Harry...I didn't get you anything..."

Harry smiled at his little friend, "it's fine Rally. That card wouldn't help my deck anyway. I don't think it would fit into it currently, truthfully I had the same idea as you."

Yusei took the cards Harry had given him, "these are Synchro monsters..."

"I spent time with this old guy on the other side of the Satellite. The dude made his Duel arena, and it was amazing...anyway, in return for a few jobs, and some duels, he gave me those. I know they're not stardust, but they could help you out still."

Yusei looked down at the cards, scrap dragon, double scrap dragon, and nuclear scrap dragon along with a few scrap tuners that were needed for the latter two, "Thanks Harry, Rally. These will help out. I'll return it. I promise." He said to Rally, knowing Harry wouldn't take them back. Rally grinned and ran back up by the others, "you ready Harry?"

"You know me. I'm always ready for doing something dangerous." Harry said as the visor teeth descended.

"Then let's ride." Yusei grinned.

The alert went up, "sir! We have a signal!"

Growling in anger he deactivated the alarms, "where."

In the eastern sector sir."

"Lock onto that signal, and figure out who the punk with him is." Turning he pointed to a man he had graduated with on the force, "you. You're helping me this time."

"Sir!" Jackson followed his lead.

Yusei jarred as another runner crashed into his, "pull over you Sattilite scum."

pull over, you are riding on an illegal duel runner.Yusei and Harry turned back and saw another sector security officer.

"Potter! I should have known you were wrapped up in all of this!" Jackson yelled through the speaker on his runner.

Jackson sped up alongside Harry, "I finally caught you! I can't believe this! You always seem to be able to squeeze your way out of trouble, but this time You and your friend are going to The Facility!"

"Know the guy Harry?" Yusei sounded amused.

Harry growled, oh he knew Jackson. Guy seemed to stick his nose in absolutely everything he did, "I built my deck and runner off of smuggled parts Yusei, sometimes this guy liked to jump in and try to catch me, you take care of him, I'll take Jackson." Harry grunted as Jackson rammed into his side.

"I'll see you on the other side," Yusei said as Harry sped up, and Jackson got on his heel.

"You're usually more sensible than this Jackson. How'd you get sucked into this bullshit?" Harry asked.

"That's none of your business, you won't be getting away from me this time." He pressed a pink section on his screen.

Harry frowned as his Duel runner shifted to duel mode. "What the hell?"

Overriding suspects duel runner

"All that work you put into that bike is what's getting you caught this time Harry. You see, with that new chip of yours I can now force you to duel me."

Harry growled as he yanked up his bike, jumping over the gate of the waste disposal factory. "You want a duel, Jackson? Bring it on." He put his deck into the shuffler.

"Let's duel!" They both shouted and placed their first hands on the cardholders.

"I'll go first." Jackson called, "I'll start by activating my supply squad spell card, and I'll end my turn by setting a monster and a card." Harry leaped down into the pipeline.

Rally groaned as the feed came online, "oh man...security is all over them already."

"It seems like Harry isn't too bugged though, he didn't hesitate to duel," Nervine said.

"You ever seen that kid duel? He's an even match with Yusei and Jack, I've only ever seen Crow beat him soundly." Blitz said.

"Either way they're running out of time. They better rev it up." Tank said.

Leaping down into the pipeline the security officer's eyes widened, "central, switch to cameras in the pipeline and warn Trudge about where he's heading."

"My draw!" Harry grinned, "I summon Alexandrite dragon in attack mode."

Alexandrite Dragon

Attribute LIGHT

Level 4

ATK 2000

DEF 100

"Destroy that facedown card."

Jackson laughed, "what's wrong Potter? Someone finally realizes those blue eyes were too good for you and take 'em?"

Harry scowled, "of course not. I've just learned to not rely on only them."

Jackson smirked, "whatever. By destroying my monster you activated my supply squad, now I get to draw a card, but I'll just draw two and start my turn." He grinned at the new card, "I'll activate a spell card called dark hole. Kinda like the one I'm going to throw you in."

Harry scoffed, "because that card destroyed a dragon-type monster I can activate the special effect of my keeper of the shrine in my hand, first I get to special summon it in defense mode, and then I get to return my Alexandrite dragon to my hand."

Keeper of the Shrine

Attribute DARK

Level 4

ATK 0

DEF 2100

This card can be treated as 2 Tributes for the Tribute Summon of a Dragon monster. While this card is in your hand or GY, if a face-up Dragon monster on the field, except "Keeper of the Shrine", is sent to the GY by a card effect or because it was destroyed by battle: You can Special Summon this card, then, if that monster sent to the GY is a Normal Monster, you can add 1 Dragon Normal Monster from your GY to your hand. You can only use this effect of "Keeper of the Shrine" once per turn.

Jackson's smirk faded, "fine then...I summon Batteryman AAA in defense mode and end my turn."

Batteryman AAA

Attribute LIGHT

Level 4

ATK 0

DEF 0

When this card is Normal Summoned or flipped face-up, you can Special Summon 1 "Batteryman AAA" from your hand or Graveyard.

Harry drew his card, "alright Jackson. I think I'll play this card just in case you get any funny ideas with spell cards. I tribute my keeper of dragons to advance summon Horus the black flame level 6!"

Horus the Black Flame Dragon LV6

Level 6

ATK 2300

DEF 1600

This card is unaffected by Spell effects. During the End Phase, if this card destroyed a monster by battle this turn: You can send this face-up card to the Graveyard; Special Summon 1 "Horus the Black Flame Dragon LV8" from your hand or Deck.

Rally stared wide-eyed at Harry's screen, "wow! That's a real-level card! I thought the only ones left were the masked Knights."

Nervin adjusted his glasses, "don't forget Rally, Harry has a bunch of old-fashioned cards that nobody has seen in a long while. One need look no further than his favorite dragons."

Rally just grinned and watched the duel progressed.

"Horus, destroy that Batteryman!" As the monster burst Harry grinned, "and now my Horus' ability activates because it destroyed a monster at the end of my turn he gets to grow up. Now he becomes level 8!"

Horus the Black Flame Dragon LV8

Level 8

ATK 3000

DEF 1800

Cannot be Normal Summoned/Set. Must be Special Summoned by "Horus the Black Flame Dragon LV6", and cannot be Special Summoned by other ways. During either player's turn, when a Spell Card is activated: You can negate the activation, and if you do, destroy it. You must control this face-up card to activate and to resolve this effect.

Jackson scowled as he drew his card, "I play the trap card Portable battery pack. This allows me to summon my battery man 9-volt and Batteryman AAA."

Batteryman 9-Volt

Level 4

ATK 1000

DEF 1000

When this card is Summoned: You can add 1 "Batteryman" monster from your Deck to your hand, and if you do, this card's ATK and DEF become double its original ATK and DEF. You can only use this effect of "Batteryman 9-Volt" once per turn. During your End Phase: Destroy this card.

"And because 9-volt was successfully summoned I can add another batteryman to my hand, and his attack points double, but he won't be around for long because by tributing batteryman 9-volt I can advance summon Batteryman charger."

Batteryman Charger

Level 5

ATK 1800

DEF 1200

When this card is Normal Summoned, you can Special Summon 1 "Batteryman" monster, except "Batteryman Charger", from your hand or Deck. This card gains 300 ATK and DEF for each Thunder-Type monster you control.

"And his ability lets me summon Batteryman fuel cell. But why stop there when I can use fuel cells ability from my hand to special summon another one."

Batteryman Fuel Cell

Level 6

ATK 2100

DEF 0

If you control 2 or more face-up "Batteryman" monsters, you can Special Summon this card from your hand. Once per turn, you can Tribute 1 "Batteryman" monster, except this card, to select 1 card your opponent controls and return it to its owner's hand.

Harry frowned as chargers attack rose equal to Horus, "I'm guessing Chargers effect is why it's so powerful."

"That's right. Batteryman charger gets stronger for every batteryman I control. Now Batteryman charger, attack Horus!" Both monsters burst into bits, "and due to supply squad I can draw another card."

Harry growled, "well I play my Keeper of the shrines effect again! Because you destroyed a dragon I can special summon this card in defense mode."

"It won't matter anyway Potter, because by sacrificing my Batteryman AAA I can return your keeper to your hand, and by banishing 2 monsters from my graveyard I can summon Batteryman industrial strength."

Batteryman Industrial Strength

Level 8

ATK 2600

DEF 0

This card cannot be Normal Summoned or Set. This card cannot be Special Summoned except by removing from play 2 "Batteryman" monsters from your Graveyard. Once per turn, you can remove from play 1 Thunder-Type monster from your Graveyard to destroy 1 monster and 1 Spell or Trap Card on the field.

"I'll end my turn by playing a facedown."

Harry swallowed heavily,Oh man...with fuel cell on the field he can get rid of anything I play. It all comes down to this card.

"I draw!" Harry called, and smirked at the card he drew.

Jackson laughed, "it won't matter what you play! My field is perfect. Even if you summon something strong enough to beat Industrial strength I can still clear it away with fuel cell! Face it, Potter, you're going down this time."

Harry grinned, "that's where you're wrong Jackson, and I'll prove it with this card. I activate the ritual card chaos form! By tributing the Blue eyes I have in my hand I can summon Blue eyes chaos MAX dragon!"

Blue-Eyes Chaos MAX Dragon

Level 8

ATK 4000

DEF 0

You can Ritual Summon this card with "Chaos Form". Must be Ritual Summoned. Your opponent cannot target this card with card effects, also it cannot be destroyed by your opponent's card effects. If this card attacks a Defense Position monster, inflict double-piercing battle damage.

His dragon rose to the field with a massive roar that echoed down the tunnel.

"Where did a punk from the satellite get ritual cards?" Jackson mumbled to himself.

"Blue eyes, attack that fuel cell!"

Jackson 6100

"due to my supply squad, I can draw a card." Jackson growled out, "now it's my turn, and by sacrificing my industrial strength I can get rid of that dragon!"

"Sorry Jackson. My blue eyes is a special card, its effect makes it so that you won't be getting rid of it unless it's by attack."

He growled, "since I have 2 batterymen on the field I can summon my third batteryman fuel cell in defense mode. But he won't be around for long because I tribute him to advance summon Batteryman charger. And his ability allows me to summon Batteryman D in defense mode."

Batteryman D

Level 1

ATK 0

DEF 1900

Your opponent cannot select a Thunder-Type monster you control as an attack target (except "Batteryman D").

"I end my turn with a facedown."

Harry drew his card, "blue eyes, attack his charger!"

"Not so fast Potter. When Batteryman D is on the field you can only attack him." Jackson said smugly.

Harry chuckled a little and accelerated a little, passing the man up, "you won't like that any better Jackson. You see when Chaos MAX dragon attacks a defense position monster it deals piercing damage, and double what you would normally take too."

Jackson 1900

Jackson screamed as his monster was destroyed, "I'll get you for this Potter."

"I'm not so sure you will, officer. It doesn't matter what you do now, even if you fill your field with monsters Charger won't be strong enough to even tie with Chaos MAX. You've lost this duel."

Jackson drew his card but stared in horror at the truth, Potters monster was a piercer, so the only way to prevent damage was to negate his attack...and the Batteryman AAA wasn't going to do that, "I end my turn..."

"Then blue eyes Chaos MAX dragon, end this duel!"

Jackson screamed as his duel runner spun out.

"So, who's your friend? How'd you convince him into breaking curfew." Trudge smirked.

"I figured you would know all about him officer. After all, you're the big bad cop."

"It won't matter anyway. Once we're done with you you'll be in the facility." He smirked, "tell you what, if you give up now I'll make sure you two share a cell."

Yusei frowned, Harry was a great duelist. It took everything he had to beat the guy since he stopped relying solely on his Blue eyes, "not gonna happen."

Trudge's smirk grew to a grin, "oh. Is that how it is? Fine then." He pressed his button and both duel runners shifted into duel mode.

Yusei frowned, "what the..."

"Like that? With the chip that you stole I can now force you to duel me."

Yusei frowned, he needed to get through the pipe. "You want a duel, bring it on." He drew his cards.

"That's what I thought you'd say," Trudge smirked, though that smirk vanished once a massive roar echoed through the pipeline.

"Seems your fellow officer is having trouble," Yusei called back.

Harry burst through the sewage plant and grunted as he flew over a security barricade, "stop!" The security force called as he barrelled past them.

Every single security officer chased after him. "That should let Yusei get through." He grunted as a stun baton made contact with his shoulder.

Trudge spun out and Yusei drifted through the door just before the trash door opened and the maintenance door closed.

Rally was cheering, "I knew they'd make it! I just knew they would."

Yusei exited the sewage plant and saw an abandoned barricade and frowned, "Yusei!" He braked and looked up to Jack Atlas, "you two made good time, didn't you? I wasn't expecting you to bring along Harry. Lucky for you he took the entire security barricade with him." He began cackling.

Yusei looked off into the distance, "be safe little brother." His eyes hardened and he turned to Jack.

Harry grunted as he was receiving one shock after another. The runes his mother had taught him to ingrain into his clothes glowed faintly, absorbing most of the shocks.

She panted as she got away from the security forces, honestly. She didn't hurt the guy on purpose, she couldn't control her powers completely, and even the device that Sayer had given her only helped reduce her powers slightly. She blinked as a whole patrol past her by, chasing a man on a duel runner.

Her eyes widened at the glowing symbols on his clothing. He flicked his hands and several different security duel runners seemed to either crash, or something seemed to crash into the bike to cause a crash, "He's like me..." a twitch of his finger and one of the security duel runners spun out. "And he can control it perfectly..."

With a loud crack, he had vanished, duel runner and all.

"Sir! He got away." She heard as they drove off.

Looking around she found him in an alleyway not too far away unconscious. Strapping him to his runner she began pushing him towards her safehouse, dark red hair spilling out of her hood as she did.

to be continued.
