A/N: I'm had this idea niggling at me for a while now and finally gave in and wrote it. It's a Justice League and Arrow (2012) crossover. Puzzleshipping and Thiefshipping are the main ships in here although there are several others if you squint as well as Oliver Queen/Felicity Smoak. Otherwise, this is a gen post-Memory World AU in which Yami/Atem chose to stay behind with Yuugi. Oh and Yami Bakura is here as well, duh since there's thiefshipping but just in case. I'm using the version of Green Arrow/Oliver Queen from the 2012 CW TV series Arrow because that version is much more fleshed out and interesting. John Diggle and Felicity Smoak will be in this as well because they're an integral part of Arrow's team as well as the few who manage to keep him sane and walking the thin moral line. However, I'm bending the CW Arrow universe/timeling a bit to suit my fic.

This will mainly focused on Seto Kaiba. I just couldn't get the image of Kaiba racing across rooftops dodging Green Arrow's arrows after dispelling a Shadow Game out of my mind. I can just see those long, sexy legs moving quickly combined with Shadow tricks as he runs from (read, toys with) Arrow and the other Justice League members. I doubt any of the League other than the main group and Arrow will show up here.

The idea for a Shadow Court is from esama's fabulous fic King's Jackel which y'all MUST READ!

This is dedicated to my Lobster Mate. *waves* Hi mate! ^_^

And now with the story...

Shadow Justice

It Begins

Kaiba groaned when his phone rang yet again. He had told his secretary to hold all of his calls for the day. Obviously, "hold all calls" meant send them directly to him instead if holding them like he should have. Why in te world had he let Mokuba talk him into letting the new boy get the job? Kaiba rubbed his temples in growing annoyance, knowing the answer. Because it was Mokuba. Mokuba could talk him into anything.

Taking a deep breath to help center himself and bury his annoyance, the young CEO of Kaiba Corpations picked up the phone. "Mushi mushi," he said simply.

"Hello, could I speak to a Mr. Seta Kaiba please?" a distinctly American voice asked politely over the line.

"This is he," Kaibe replied in English. "May I ask who is calling?"

"Ah, yes, I am Alexander Luthor of LexCorp. I was wondering if I could borrow a few minutes of your time? I'm told you will be visiting Starling City, Oregon, for business soon. I will as well and I was wondering if you would mind meeting with me. I have a business proposition I'd like to discuss with you."

Kaiba rolled his eyes. "I can't guarantee anything, Mr. Luthor."

"Please call me Lex," Luthor interupted. "Mr. Luthor was my father."

A bright blue eye twitched. "As I was saying, as of now, my schedule is full. I'll contact you if I have an opening."

"Of course," Luthor replied, smoothly accepting the subtle decline. "I'll be in contact then."

Before the man could say more, Kaiba hung up. He swiped a hand down his face rubbing his forehead And pinching the bridge of his nose. Damn it all. He had been hoping to keep his visit to America on the down low. He would have to find out who let the news out and give them a firm stripping down of their duties. Standing, the brunette turned to face the wall of floor-to-ceiling windows of his office in the KaibaCorp Tower. Thoughts whirled in his head, none escaping to show themselves on his calm, cool visage.

He was not too excited about returning to America since the DOMA incident. There was no reason to blame an entire country for something that had nothing to do with it except for serving as the backdrop for a series of unfortunate events. He still had nightmares of losing Mokuba's soul and feeling helpless to do anything but watch and then the horrendous shredding sensation as his own soul was forcefully ripped from his own body. No one involved in DOMA, the madness that was Duelist Kingdom, the MORPG, or even his own Battle City events escaped unscathed.

The difference was a select few had recovered enough to continue on. Well, perhaps recovered was not the correct word; overcome would probably be the better word choice. They had overcome the trauma and decided there was no use dwelling on it. Instead, they learned from their experiences and decided to use what they learned.

Since acquiring Industrial Illusions, Kaiba Seto, CEO of Kaiba Corporations, was now the second richest person on the planet behind the American Microsoft genius Bill Gates. Lex Luthor of LuthorCorp followed on Kaiba's tail, close enough to keep an eye on but not close enough to fear, yet. Bill Gates was a goal Kaiba intended to reach and surpass. Lex Luthor on the other hand was more than a businessman; that much Kaiba was well aware of. The man reminded Kaiba too much of himself in a way that did not sit well with the CEO. Luthor reminded Kaiba of the way he had been before the Pharaoh's infamous Mind Crush curse. That was something Kaiba Seto had no desire to repeat in any sense of the word.

Speaking of the Pharaoh, the brunette felt a tug from the Shadows and did not need to turn to recognize the presence behind him. His eyes narrowed as did his Shadow senses; make that two presences.

"You're late," he said simply in hieretic.

Two voices chuckled behind him, one deeper than the other. "My apologies," the deeper voice replied in kind.

"We were busy. Grandpa got home later than expected due to traffic so we had to stay at the game shop until he arrived," the younger voice continued.

Kaiba harrumphed and shrugged his shoulders in an gesture of dismissal. "I figured. Any news from the others?"

The younger voice answered, steadily moving closer until its owner stood beside the CEO looking out the window. "I've contacted the Sorceress and the Emissary. Neither are in the area but they've told me what they know. Starling City is watched by a member of the Justice League."

"Arrow, yes I'm aware," Kaiba said, eyes narrowing.

The young man next to the CEO nodded. "That's what the people of Starling City call him. The Justice League apparently calls him Green Arrow."

Kaiba scoffed. "That sounds about as ridiculous as your hair."

The youth chuckled while the owner of the deeper voice balked at the insult. "It's alright, Yami," the owner of the younger voice soothed. "I don't mind. Besides, you know it's true."

Yami stepped next to his younger companion and sighed gustily. "Well, I don't remember having any say in what I looked like then or now. Then it was a product of genetics and my close association with the Shadow Realm. Now," crimson eyes slid sideways to meet the soft violet of his nearly identical companion, "it's a product of your genetics and my mimicry."

"Careful Pharaoh. You came first, so the blame for Yuugi's genetics falls squarely on your shoulders," Kaiba said.

The Pharaoh snorted. "As I recall. I died before siring any children. It was you who continued the royal line. So I believe that makes you the guilty party."

"Not so," Kaiba countered. "I died wifeless and childless." Sharp blue eyes narrowed. "Like hell I was going to sleep with anyone other than Kisara."

The mood in the room dropped back to darker levels as memories both welcome and unwelcome filled the silence. It was Yuugi who eventually spoke first. "The Emissary said she would try to meet you in Starling City but she couldn't guarantee anything because she's currently performing in New York. The Sorceress promised to get there as soon as she could. But it would most likely not be in time to meet you."

"That's fine," Kaiba replied. "I can handle myself. It's not like this is my first trip outside Japan; or anywhere near my first. I don't need a babysitter."

Yuugi smiled while Yami snickered. "So you say."

Kaiba glared at the taller of the two virtually identical individuals standing next to him through the corner of his eyes. "What are you implying?"

Yami shrugged. "Nothing, nothing."

"Is Mokuba coming with you?" Yuugi asked, breaking the tension between the other two.

"Not immediately, no. I want to get the layout of the situation before I bring him into it. Besides, he's still recovering." Blue eyes returned to the cityscape of Domino. He planned on leaving for the company plane in a few more hours. If he planned everything right, he would arrive in Starling City in the early hours of the night. He did not want to attract more attention than was necessary. Besides, he worked best in the Shadows.

"Another Game was played," Yuugi said softly, breaking into Kaiba's thoughts.

The CEO stiffened, eyes darkening furiously. "How many deaths?"

"Three."

"Che, idiots," Kaiba hissed viciously. "They have no idea what they're dealing with."

"Maybe they don't," Yami said, voice hard. "But that doesn't change anything. The punishment is still the same. Ignorance is no excuse."

"If you need us," Yuugi said, turned to face Kaiba directly, "don't hesitate to call. We'll come as quickly as we can."

"Who knows," Yami said, "we may join you just because."

"I'd rather you didn't," Kaiba grumbled.

"Your opinion has been noted my Regent," Yami said with a smirk.

"And ignored," Yuugi finished with a grin.

Kaiba sighed in resignation, one hand slipping into a pants pocket while the other covered his face in mild frustration. "I do not need this right now."

"Yes you do. You wouldn't like it any other way," Yuugi chirped. "You couldn't exist without someone to push against. You need a constant challenge."

Kaiba hesitated before speaking again. "I wasn't referring to you. Lex Luthor called me and my idiot secretary patched him through even though I explicitly told him not to." The hand covering his face lowered to slip into the other pants pocket. "He wants to meet me when I get to America. I informed him of my busy schedule but I don't think he cares. He'll definitely try again. I don't like the way he handles things. He's a good businessman but I doubt his interference in this is coincidental."

"I know of Luthor," Yuugi said quietly. "He's an American businessman, correct?"

Kaiba nodded. "Mainly real estate but he dabbles in chemical engineering and technology. He's decent with technology but nowhere near my level. I'm mainly concerned with what Luthor's interest in all this is." Kaiba glanced at the identical due once more. "If he comes to Starling City, Superman won't be far behind. And where Superman goes-"

"The Justice League goes," Yuugi finished.

"As does the media. And with Arrow already there…"

Kaiba returned his attention to the city for a moment before turning to grab his long white trench coat. "I'll inform you of my findings."

Both Yuugi and Yami nodded. "By the way," Yami called after the CEO, "have you given any thought as to where the new Battle City will take place?"

Kaiba smirked. "Let's just say I have several options open."

Yami snorted and rested his arms possessively around Yuugi's neck, leaning on him from behind. "I look forward to hearing your ideas."

"Are you implying I have to go through you to host my own Battle City Tournaments?" Kaiba asked in mock offense.

Yami shrugged. "I am the Pharaoh."

"And I'm the Regent," Kaiba replied. "I have just as much authority as you and the King do," he said, nodding to the faintly blushing Yuugi. "You know that."

"And what an interesting Triumvirate we make."

Yuugi groaned before switching to Japanese. "I can't believe you two."

Yami grinned, nuzzling Yuugi's neck affectionately. "I was merely finishing what he started."

"Yes, because we all know who tops in this mess," Kaiba said before leaving the room.

Yami and Yuugi started dumbstruck at the door before bursting into cackles, vanishing into the shadows.
