Disclaimer: I do not own Yu-Gi-Oh! GX, Young Justice, or any part of the Yu-Gi-Oh! or DC franchises.

Well, how this story came about was kinda interesting. I was originally toying with the idea of doing a GX super hero story inspired by the various Hero cards, then later the concept evolved into one that would have various characters as superheroes based off of some of their cards. Even later on, a friend of mine that I was talking with about the story made a joke that since I like crossovers so much, I should just cross it over with actual superhero stuff. Long story short, I decided thats exactly what I would do, and evetually settled on DC stuff.

Now, my knowledge to DC materials is limited to 80% watching the various shows that have been on TV, and 20% reading some of my friend's comics based on my all-time favorite DC hero, and a few others. So setting it in one of the newest DC based series, Young Justice, was a perfect choice since its so new and set in its own universe, meaning I won't have to read through inumerable stuff to avoid contradicting too much.

Anyway, this story will have several GX characters in super heroic roles, as well as some characters and monsters in villainous roles. I'll be adding at least 3-4 GX characters to the Team, with others making a variety of different appearances. And if this story continues(which for now, I plan to as long as I see enough people are interested), I also may or may not decide to include some other DC characters that haven't appeared yet in the series.

But enough of my ramblings, on to the story.

Gotham City
July 4

In Gotham's park, many people were enjoying the beautiful day and the birthday of their nation. On family in particular was enjoying a barbecue, with the father passing a pair of hot dogs to his daughter.

Suddenly, with screams, people began to run pass their location. Following them, a large freezing blast swept through the area, encasing all that it struck in ice.

A top a nearby stone hill, a man wearing what resembled a black and blue space suit holding a large gun-like weapon. Only the man's head could be seen through the helmet, and his skin was a very pale white. The man was known as Mister Freeze, a villain who used, as his name would imply, freezing weapons.

"Enjoying family time?" he asked as he saw the people below him. He then aimed his weapon at them at let loose another freezing blast, and they were encased in ice, like many others in the area. "My family has other plans." He then slid down an ice path, and aimed his gun at the crowd of people still fleeing, and was about to fire on them when it was suddenly struck by a black, bat-shaped boomerang-like weapon.

"Batman." he began as he turned to face the direction that the weapon had come from. "I was wondering when..." His voice trailed off when he saw no one. However, he did hear the echo of a cackling laughter. Looking around, he still saw no one. When he turned around, a pair of feet kicked down on his helmet and leaped off him, causing Freeze to fall forward, as the owner of the feet, a costumed boy threw a pair of shuriken like weapons at Freeze's helmet, causing it to crack a bit. The boy in question was known as Robin, the boy wonder. He had a confident smirk as he stared down the villain.

"Boy wonder. The bat sent you to drag me off to prison?" Freeze questioned the boy as he got to his feet. "Frankly, I'm underwhelmed."

"Great, but I'm kinda in a hurry here." Robin said.

"Kids. Always in such a rush. I prefer to keep these moments preserved. Forever." Freeze said as he took aim at the boy.

"Not talking to you." the boy wonder said in

At that, Freeze realized who the boy was really talking to, and turned around just in time to see none other than the dark knight himself, Batman, leap up, and come down, delivering a punch that shattered his helmet.

Star City
July 4

On a suspension bridge, in the middle of the road, a young man whose body appeared to be made of ice landed, and created a patch of ice that then rose up creating an ice wall, causing some cars to become overturned. This young man was known as Icicle Jr.

He laughed maniacally at the havoc he was causing, when suddenly a few arrows struck the ice wall near him, and one embedded into his shoulder. After a few moments, each arrow exploded. Though despite the explosions, Icicle Jr. was relatively unharmed.

Looking over in the direction the arrows had come from, he saw a pair standing atop the nearby tower were a pair of archers, one dressed in green and another in red. They were known as Green Arrow and his protege Speedy.

However, despite being there to stop him, Icicle Jr. actually seemed pleased to see them. "Finally! I was beginning to wondering what a guy had to do to get a little attention around here!" he said as his arms began to grow, and he threw large ice spikes at the two archers.

"Junior is doing this for attention?" Speedy questioned as he and his mentor shot several of the spikes with their exploding arrows. They took out most, but not all, so they dodged to the side, and began to run down the cable towards the superpowered villain before them. "I'm telling you now, this little distraction better not interfere." Speedy told Green Arrow as they ran and both fired an arrow at their enemy.

Seeing them coming, Icicle Jr. used his powers to create a wall of ice between him and the arrows, which exploded after they hit it, creating a hole in it. Through the hole, the ice man flung more ice spikes at Speedy, who leaped out of the way, pulled out an arrow, and fired it through the hole, and struck Jr in jaw, and he fell to the ground unconcious.

Green Arrow let out a chucle. "Kid had a glass jaw." he commented.

"Hilarious. Can we go?" Speedy said, clearly not amused by his mentor's joke. "Today is the day."

Pearl Harbor
July 4

On the deck of a battleship frozen in ice, a woman with pale white skin and blue hair, wearing blue and white fired freezing blast from her palms.

Her target was a bearded man with blond man wearing orange scale-mail tunic and dark green leggings and gold gauntlets. He was Aquaman, the king of Atlantis. He dodged most of her blasts, but was hit with one, and all but his head was encased in ice in an instant.

As he was frozen, another person, a boy with dark skin and blond hair wearing skin-tight, full-body, red-and-blue swimsuit that exposes his arms and feet. The boy was known as Aqualad, and Atlantean that was the protege of his king. Aqualad leaped over his king and ran towards Killer Frost. As for Aquaman, it didn't take long for him to break out of the ice that held.

"Don't tell me you're not excited." he said to his partner.

"Right now my king, I'm more focused on the matter at hand." he replied. Dodging several more freezing blasts and leaping over one, Aqualad pulled out a pair of weapons from his back. Using them, water gathered and formed a mace on each one. Killer Frost then fired a freezing blast at the Atlantean boy, he blocked it with his weapons and a block of ice formed around his hands and weapons as he landed in front of the villainess. However, this did not deter him, and without a moments hesitation, he smashed the block of ice in her face. This caused his hands to be freed from it and also knocked Killer Frost unconscious.

"Well?" Aquaman asked, refering to his earlier question.

"Yes, I'm excited." Aqualad replied. "Today is the day."

Central City
July 4

Outside a jewlery store that had ice surrounding its entrance, a man wearing blue clothes that resembled an eskimo's was firing his freeze gun at a pair of heroes that were literally run circles around him. One was a man wearing a red, full-body jumpsuit, and the other was a boy wearing a yellow costume with red pants whose red hair was sticking out at the top of his costume. The two were the Flash and his sidekick Kid Flash, and the villain that was firing his freeze gun at them was Captain Cold.

"Stealing ice? Seriously?" Flash questioned. "Isn't that a bit cliche, even for Captain Cold?"

"C'mon, we don't have time for this!" Kid Flash complained as he pulled his red goggles over his eyes. He then ran straight at Captain Cold, who fired at him, only for Kid Flash to dodge, and run past him, taking the man's weapon as he did.

Realizing what had happened, Captain Cold was angry, though the anger didn't last long as the Flash punched the disarmed villain in the face, knocking him unconscious.

"Calm down, Kid." Flash said to his sidekick.

"Oh please! You'll chat it up with the cops, with bystanders, with... Cold even! No! No way!" Kid Flash replied with annoyance. "Today is the day!" he then exclaimed with excitement.

Domino City
July 4

A woman with long, blue hair, wearing ony white cape walked down the street. Her skin was pure white, and her body was covered by ice in various places. At the sight of the practically naked woman, nearly everyone in the area began to flee. At this, a wicked grin appeared on the woman's face, and she held up her hand and a powerful freezing wind began to blow from it, and people and objects alike began to freeze. The villainess, who was known as the White Night Queen, let out a cackle at the sight. As she was about to continue her advance through the street, a pair of energy blast struck the area in front of her.

Floating above was a muscular, humanoid, white figure. It had no mouth on its face, and arching from its head was a single antenna, and all in all, had a bit of an alien appearance. Standing nearby on a rooftop was a younger, similar looking figure. The larger one was the powerful elemental hero, Neos. The other was his sidekick and partner, Neos Alius.

"Neos, how nice of you to show." White Night Queen said.

"I'm here too, you know." Neos Alius chimed in.

"A sidekick makes no difference." she said as she held up her hands and created ice that took the form of a large dragon that took flight, and flew at Neos.

"I'll take down her dragon, while you deal with White Night Queen." Neos said as he flew towards the approaching ice construct.

"Aw, you always take all the fun stuff for yourself." Neos Alius said as he leaped down to the streets.

"Hey, you want this done quickly, don't you?" Neos asked with a chuckle as his body was engulfed in flames and his form became black and orange, and took a more insect-like appearance with wings and a pair of antenna resembling pincers on his head.

"Of course!" Neos Alius replied excitedly as he landed, and rushed at White Night Queen, ducking under her freezing attack.

In the air, Neos unleashed a powerful blast of flames that melted the ice dragon in seconds, while Neos Alius simultaneously gave a powerful punch to White Night Queen, sending her flying back a great distance thanks to his super strength, and she colided with a wall. She then fell to the ground, already unconscious from the

"Well, that was a fun little side trip. Now, lets go!" Neos Alius said to Neos as he landed and reverted to his normal form. "Today is the day!"

Washington, D.C.
July 4

Gathered together, Batman, Robin, Green Arrow, Speedy, Aquaman, Aqualad, Neos, and Neos Alius stood accross from a grand and majestic building; the Hall of Justice.

"Today is the day." Batman said as he placed a hand on Robin's shoulder.

"Welcome to the Hall of Justice." Green Arrow said.

"Headquarters of the Justice League." Aquaman finished.

"You guys have all earned this." Neos said giving Neos Alius a pat on the back.

"Oh man!" a voice let out in frustration as Flash and Kid Flash came running over to join them. "I knew we'd be the last ones here!" Kid Flash said as he crossed his arms.

"Ah, don't worry about getting here a few minutes late, KF." Robin said.

"Yeah, you know we'd never go in there without you." Neos Alius reassured.

"I know, I know." Kid Flash said. "But do you know how embarrassing it is for someone with super speed to be the last one to arrive?" he said, sending a glare towards the Flash.

After Kid Flash had finished his complaining, the group of heroes made their way towards the building, with a variety of tourists taking an interest as the heroes walked down the path to the building.

"Is that Batman?" a man asked another as he noticed them.

"Look mom, its Neos!" a child marveled at the sight of the hero as he tugged on his parent's sleeve and pointed at him.

"I see Flash, and Flash Jr." a woman said.

"His name is Speedy, duh." a man ciorrected her.

"No, Speedy is Green Arrow's sidekick." another man corrected him.

"Well that makes no sense."

"Ready to see the inner sanctum?" Green Arrow asked Speedy.

"Born that way." was his reply.

"I'm glad we're all here." Aquqlad said to his friends.

"Yeah, I agree." Neos Alius said. "I'm glad we're all getting to do this together."

"Have all for sidekicks ever been in the same place at the same time?" Kid Flash asked.

"DON'T call us sidekicks." Speedy replied sternly with great annoyance. "Not after today."

"Sorry." Kid Flash replied. "First time at the hall. I'm a little overwhelmed."

"You're overwhelmed, Freeze was underwhelmed. Why isn't anyone ever just 'whelmed?'" Robin said. At that, the group had finally entered through the front gate, and were met with the great sight of seven huge statues of the founding members of the Justice League. It was quite the sight to see. "Oh. Maybe thats why." he let out in awe.

Under the statue of Superman, a door that had a sign that said 'Authorized Personnel Only' on it opened, and out stepped two figures, neither of which were human. Both fellow members of the Justice League, they were they alien Martian Manhunter and the robotic Red Tornado. "Robin. Speedy. Aqualad. Kid Flash. Neos Alius." Martian Manhunter adressed each of them. "Welcome."

And with that, he lead them all inside. As they all followed inside, Robin, Kid Flash, and Neos Alius each bumped their fists together. They, and Speedy and Aqualad, had been looking forward to this day for a long time. The day that they would become more than just partners to their respective mentors.

"You now have unlimited access to the gym, our fully-stocked galley, and of course, our library." he said as they all entered into said room. The inside was large, and as impressive as you'd expect from everything in such a building.

"Make yourselves at home." Flash said, and at that, Robin, Aqualad, Kid Flash, and Neos Alius each to a seat. Speedy remained standing.

"Man, I almost can't believe that this is happening." Neos Alius said. "I get to be part of the Justice League! If I'm dreaming, don't ever wake me up!"

"Hey, don't go fanboy on us, Jaden." Kid Flash teased.

"Heh, sorry, but I can't help it." Neos Alius replied with a chuckle. "I'm just so excited to join the League." For Neos Alius, real name Jaden Yuki, this really was a dream ome true for him. Growing up, he had always looked up to the great super heroes like Superman, Batman, and the rest, and had wished that he could be like them. He had been ecstatic when he had joined Neos as Neos Alius, and getting to become a real super hero himself. And joining the Justice League truly was a dream come true for him.

"Hey, cut him some slack, Wally." Robin said. "Don't act like you don't feel the exact same way as him. You know you're thinking exactly the same thing."

"We are all just as excited." Aqualad said. "We are each just showing it in our own way."

Speedy meanwhile, was looking over to where the full members of the Justice League were. "Quick debrief to discuss the 'coincidence' of five ice villains attacking on te same day." Batman said to the five proteges. He obviously didn't believe that such an event was coincidence. He wanted to find out what was possibly going that he wasn't aware of yet. "We shouldn't be long."

And with that, they walk over to another area where a light began to scan over each of them as it analyzed their biometric data. "Recognized. Batman, 02. Aquaman, 06. Flash, 04. Green Arrow, 08. Martian Manhunter, 07. Neos, 17. Red Tornado, 16." a computerized voice said as it confirmed their identities. Another door labled 'Justice League Members Only' opened for them.

"Thats it?" Speedy demanded. "You promised us a real look inside. Not a glorified backstage pass."

"Its a first step. You've been granted access few others get." Aquaman replied calmly.

"Oh really?" he said as he gestured up to windows where tourists were looking in and taking some pictures. His frustration at the situation was evident in his voice. "Who cares which side of the glass we're on?"

"Roy, you just need to be patient." Green Arrow told him.

"What I need is respect." he said, then turned around to look at the other young heroes, his anger increasing each moment. "They're treating us like kids. Worse, like sidekicks." he said the last word with disgust. He hated being thought of as nothing more than a sidekick. He was just as much the hero that his mentor Green Arrow was, and wanted to be seen as such by others. "We deserve better than this." he said to them, and they remained silent as they exchanged glances. "You're kidding, right? You're playing their game? WHY? Because you think they play fair? Today was supposed to be the day. Step one to becoming full fledged members of the League!"

"Well, sure." Kid Flash agreed. "But I thought step one was a tour of the HQ."

"Except the hall isn't the League's real HQ!" Speedy said, shocking the four others. "I bet they never told you that the Hall is just a false front for tourists, and a pitstop for catching zeta beam teleporter tupes to real thing! An orbiting satellite called the Watchtower." he explained to them.

The other League members were all glaring right at Green Arrow right now, knowing exactly where Speedy had heard such classified information. "I know, I know, but I thought maybe we could make an exception?" he apoligized. Batman's faced remained just as stern, with the only change being that he narrowed his eyes. "Or not." he said, looking a bit disappointed.

"You are not helping your cause here son." Aquaman said. "Stand down, or-"

"Or what? You'll send me to my room? And I'm not your son! I'm not even his." he said as he looked towards the other archer. "I thought I was his partner, but not anymore." he said as he removed the hat on his head and threw it to the ground to everyone's shock at the situation. "Guess they're right about you four." he said as he walked past his friends. "You're not ready." And with that, he left.

Before anything else could happen, there was a loud blaring noise, and the image of Superman appeared the large computer monitor. "Superman to Justice League. Theres been an explosion at Project Cadmus. Its on fire." he said.

"I've had my suspicion about Cadmus." Batman said. "This may present the perfect opportunity to-" he was cut off as the call alert went off again.

"Zatara to Justice League." The image of a man dressed like a magician appeared on the monitor in the corner, "The sorcerer Wotan is using the Amulet of Aten to blot out the sun! Requesting full League response!"


"Its a small fire. Local authorities have it under control." the man of steel replied.

"Then Cadmus can wait." Batman said, then pressing a button on the console. "All Leaguers rendezvous at Zatara's coordinates. Batman out." he ordered with urgency. He then turned to the young heroes. "Stay put."

"What? Why?" Robin questioned for the group.

"This is a League mission." Aquaman said.

"You're not trained." Flash said.

"Since when?" Kid Flash demanded.

"I meant you're not trained to work as part of this team."

"There will be other missions. When you're ready." Aquaman explained.

"For now, stay put." Batman ordered.

"Glad you didn't bring 'you-know-who?'" Green Arrow asked Martian Manhunter.

"Indeed." the alien replied, and with that, the members of the Justice League all filed through the door, leaving the remaining four young heroes alone.

"Tch, 'When we're ready?' How are we ever supposed to be ready if they treat us like... like sidekicks!" Kid Flash complained. It was becoming more and more apparent that Speedy was right.

"My mentor... My king... I thought he trusted me." Aqualad lamented.

"Trust? They don't even trust us with the basics! They've got a a secret HQ IN SPACE!"

"What else aren't they telling us?"

"I've got a better question: Why didn't we leave with Speedy?" Robin asked.

"Man, this all sucks." Neos Alius said. "I thought today was supposed to be our big day, but nothing ha changed at all..." Needless to say, Jaden was disappointed. Today he had hope to become a member of the Justice League, but that hardly looked to be the case right now. They barely trusted them with their secrets, and wouldn't even take them on a big mission like this.

The four remained silent for a moment before Aqualad spoke up. "What is 'Project Cadmus?'"

"Don't know." Robin said. "But I can find out." he said as a grin appeared on his face. And with that, walked over to the computer console and began to search for their desired information.

"Access denied." a computerized voice told him as said words appeared on screen.

"Heh, wanna bet?" he said keying in several commands, and with that, the 'Access Denied' disappeared as he gained full access into the system to find the information.

"Woah. How are you doing that?" Kid Flash asked as he watched the boy wonder work his magic.

"Same system as the Batcave." was his response. And with that, he preformed his search once again.

"Access granted."

"All right, Project Cadmus. Genetics lab here in D.C. Thats all there is." Robin read. "But if Batman is suspicious, maybe we should investigate." he said slyly suggested.

"Solve their case before they do. It would be poetic justice." Aqualad said.

"Hey, they're all about justice."

Aqualad let out a sigh before saying "But they said stay put."

"For the blotting out the sun mission, not this."

"Wait, are you going to Cadmus?" Kid Flash asked. "Because if you're going, I'm going!"

"And you guys can count me in, too!" Neos Alius said. "After all, I can't let you guys have all the fun!" he said, and with that, the three of them each turned to Aqualad expectantly. "You're in too, right Kaldur?"

"Just like that, we're a team on a mission?" he asked them.

"We didn't come here for a playdate." Robin said. The four young heroes were in agreement. They were more than just their mentors' sidekicks and proteges; they were all heroes as well. And if they weren't going to be treated as such, then they would just go off on their own for now. "Okay then, you guys all ready?"

"You know it!" Kid Flash said.

"I'm always ready for anything!" Neos Alius said, the two giving each other a high five.

And with that, the four of them left the Hall of Justice for their destination, not knowing just what they would discover or what would come of it.

And there we go. So what did you think? Like it? Yeah, a lot of the same here, but that won't always be the case. I've got some stuff planned. For now though, gotta go with the plot flow to get to Superboy. Jaden/Neos Alius will be the first of the GX characters as a hero in this as part of the Team, and the others will show up at some point after the Team is formed. Tell me your thoughts or ask me you're questions, heck I'd even be fine with criticism as it could help me improve, but please review.
