This is actually a fanfic I've been wanting to do since I started my re-writes, while it might be a bit, unusual to do this story, I am going to try and hopefully succeed at making this a good story.

For as long as I've worked in Yu-Gi-Oh fanfics, I've been crossing it with X-Men, and recently I've been working on re-writing my older stories, while this one isn't as old, I wanted to still make it better.

So, let us begin.

Disclaimer: I do not own Yu-Gi-Oh or X-Men.

PROLOGUE:

INVADING REALITIES

00000

Hard to believe its been 20 years now, 20 years since the Mutant War happened and we left our home in Haven...

Since then we have made friends and allies, built a home for ourself in Japan in a community we have come to know as Seidou. Originally settled for Mutant refugees who lost their homes during the Mutant War, it has since become something, more.

Soon after we settled in Seidou, others came asking to live there, a few of us could see that they where different as well. Elves, Orcs, Dwarves, and other creatures that many of us believed only existed in the realm of fantasy, we came to know these beings as Shadowkind.

Since then, Seidou has become a sanctuary not only for Mutants, but for anyone who is different. And since then the Shadowchasers, an organization that works to ensure that Shadowkind is kept safe and that the world is safe from those that would cause hurt as well, they have come to Seidou as well.

During my youth, I fought many an enemy, some alone, others with my team, and I have come to respect the Shadowchasers and their leader. I suppose, in a way we're not that different, the only difference is that the world as a whole knows about us while Shadowkind are still hidden.

Then, when the incident happened, some asked me if I regretted my decision to welcome the Shadows to Seidou as I did. I regret many things, but that decision was not one of them, Seidou is open to all.

Who am I? My name is Rogue, and I am an X-Man.

EVOLUTIONARY BRIDGE:

AFTER A STORM

000000000

00000

Now, where to begin? I suppose at the beginning, what happened in Seidou?

To answer that question, you must understand where we where coming from, Seidou had been at peace for 20 years, the X-Men where only needed every so often, but we continued their existance in the event that the need for them rose again.

In the meantime, Duel Monsters has become popular among the students and others in Seidou even to the point that the Memorial Stadium has become a landmark of our city.

But our story begins elsewhere, where one of the allies of the X-Men are dealing with a, different sort of problem.

The McCoy memorial hospital was one of the structures built in Seidou after it had been made a sanctuary after the end of the Mutant War. It was late, and the lower levels where mostly empty, but the door to the morgue opens, and a figure silently moves inside, moving towards one of the alcoves, it starts to open it when the light goes on.

"You know, I don't think the family would look too kindly on the body of their loved one being desecrated like that," a woman's voice says, standing in the doorway is a young woman with long white hair, wearing a black shirt and blue jeans with a white trench coat over it, a sword strapped to her back. "You just don't learn very well, do you Eito? Not even out a week and you're trying again."

"Well, you know what they say, Leia, at first you don't succeed," Eito says, Leia rolls her eyes, Eito was a Necromancer that had become obsessed with the idea of replicating Frankenstein's experiments with the Flesh Golem, with very little success so far. Leia had put him in jail, but his lawyer had managed to get him out on a technicality, and he was apparently trying again. "So, then what's it going to be, Kaiba? You're still bound by the Great Treaty after all."

"Yes, I am," Leia says, raising her arm with a duel disk strapped to it, taking out a deck and putting it in its slot. "And I'm not afraid of your zombies, Eito."

"Oh, but I have a whole new strategy to go with them," Eito says with a grin, putting a duel disk on his arm with a deck. "Lets see if you can stand up to it."

"DUEL!" They say in unison as they activate their duel disks.

(Leia Kaiba: 8000) - (Eito: 8000)

"I'll go first, Shadowchaser," Eito says, drawing his first 6 cards. Perfect, there's the key card to my whole strategy, but I can't use it yet, he thinks, picking another card from his hand and placing it on his disk. "My turn will simply consist of setting one monster in defense mode, your move."

"Fine, then its my draw," Leia says, drawing a card. "I start with my Hieratic Dragon of Gebeb (1800/400)!"

An orange scaled dragon on its hind legs with golden armor appears with a roar that shakes the room.

"Gebeb again, huh? Still using those Hieratic monsters, go on, I'm not worried," Eito says.

"Well, here's a card you might remember, I play the spell Hieratic Seal of Convocation, so I can add one Hieratic monster to my hand," Leia says, taking out her deck and selecting a card. "Then I'll set one card face down, and attack your face down monster with Gebeb, use Searing Light attack!"

The dragon rears its head up, and breathes a stream of light on the face down monster, which briefly appears as a grey rat before shattering.

"Thanks, that was my Giant Rat, now I can special summon one earth monster from my deck to the field," Eito says, taking a card out of his deck, and a red armored samurai appears. "So, I summon my Zanki (1500/1700) to the field in attack mode."

Huh, why would anyone use Zanki? Leia thinks, then shrugs. "I use Gebeb's effect, and special summon Hieratic Seal of the Sun Dragon Overord (0/0) to the field," she says, and a massive spherical monster with a red eye symbol on its front. "And that's all for my turn, lets see what you've got."

Eito draws a card. "Fine, I switch Zanki to defense mode, and set one monster in defense mode," he says, and the Samurai kneels in defense mode. "And now I activate my spell card, Ancient Rules, so I can..."

"I activate my trap card, Hieratic Seal of Reflection, so I sacrifice my Seal of the Sun Dragon Overlord, and I can negate your spell card," Leia counters as a barrier appears as the large monster shatters, and the seal closes in on the spell, shattering it.

"Fine then, I'll set two cards face down, and end my turn," Eito finishes, looking over his hand. "I end my turn there."

Okay, this is getting weird, I can't help but feel that he's leading me into something, Leia thinks as she draws a card, sliding it into her disk. "I'll set one card face down, and summon my Alexandrite Dragon (2000/100) in attack mode!" She says, and a dragon appears that's made up of gems. "And before I do anything else, I play the spell card Stamping Destruction, destroying your face down card and dealing 500 life points of damage."

Eito barely flinches as Gebeb stamps down on the face down card, revealing it as Mirror Force.

Go ahead Shadowchaser, you're just using your cards up, and soon I'll bring out my big surprise, Eito thinks, looking at a card in his hand.

"Now Gebeb, attack his face down monster with searing light!" Leia commands, as the dragon breathes its burst of light, shattering the face down monster which is briefly revealed to be an ugly clown monster holding a scythe. Okay, this is getting weird, why does all this sound familiar? Leia thinks.

"Are you going to do anything else, Shadowchaser?" Eito asks.

"Alexandrite Dragon, its your turn, attack his Zanki with Crystal Flame attack!" Leia says, as Alexandrite Dragon breathes fire on the Samurai, shattering it. "And that's it for my turn."

(L: 8000) - (E: 7500)

"Its my draw!" Eito says, drawing a card quickly. "Now, lets make this interesting, I play Lightning Vortex!" He says, taking a card and sliding it into his graveyard, then lightning rains down, shattering both of Leia's dragons. "And now, because I have Crawling Dragon, Zanki, and Crass Clown in my graveyard, I can play the spell card, Call of the Haunted!"

"Call of the Haunted? That's a..." Leia starts to say, but stops short when she see's the card, it indeed has the same picture as the more well known trap card, but it is a continuous spell card. "Oh... you gotta be kidding me."

"That's right, I believe your great uncle had a little run-in with this version of Call of the Haunted, by removing from play the three monsters, I can summon to the field Dragon Zombie (1600/0), Armored Zombie (1500/0), and Clown Zombie (1350/0)!" He says and three monsters appear, the first one resembles a dragon, but is rotting with ragged wings, the second resembles a one eyed zombie with the armor of a Samurai, and finally the third was a zombie version of Crass Clown. "And now, I play the trap card, Trap Stun, so you can't activate your trap cards."

He's clever, my face down card could have kept me safe, Leia thinks. And now I'm defenseless...

"Now, my monsters, attack her directly!" Eito says, as his monsters attack, Clown Zombie and Armored Zombie using their weapons, while Dragon Zombie breathes noxious fumes on her, knocking her down on her butt. "And, that'll end my turn there."

(L: 3550) - (E: 7500)

Okay, where did I lose control here? Leia thinks, drawing a card. "I start by using the effect of my Hieratic Dragon of Tefnuit that I added to my hand earlier, allowing me to special summon it in attack mode (2100/1400)," she says, and another dragon appears, this one is colored white, with the same golden armor as Gebeb. "And I summon my Hieratic Dragon of Nuit (1700/900) as well."

The monster that appears next is colored light blue, it lets out a roar as it does.

"Yes, but I remember distinctly that your Tefnuit can't attack this turn because of its own effect," Eito points out.

"That's why I'm summoning someone who can, I remove from play Gebeb and Alexandrite Dragon to special summon Hieratic Dragon of Asar (2600/700)!" Leia says, and a serpentine green dragon with four small arms and golden armor appears.

"You didn't use that card before!" Eito says.

"I didn't draw him in our last duel, I'm afraid," Leia says. "But that doesn't matter much, does it? Asar, attack his Clown Zombie with Emerald Inferno!" She commands, and Asar rears its head, charging up a fireball and sending it at the clown zombie as it shatters. "Now Nuit, attack his Armored Zombie, Holy Lightning!"

The dragon crackles with electricity, and a beam of lightning shoots out of its mouth, striking the undead samurai.

"I guess that's the end of your zombies, I place one card face down, and end my turn," Leia finishes as a face down card appears in front of her.

(L: 3550) - (E: 6050)

"The end? Hardly, Miss Kaiba," Eito says, drawing a card, then Clown Zombie and Armored Zombie appear again on his side of the field, Armored Zombie's attack goes up to 1650 and Clown Zombie's goes up to 1485.

"What, how did you do that?" Leia akss, surprised.

"Clearly you don't know all the tricks to my spell card," Eito says. "When they're destroyed while I have Call of the Haunted on the field, they come back with a bonus of 10% of their attack points."

Now I remember this card, Bonz used it against Joey Wheeler during Duelist Kingdom, I heard that some people still used it, Leia thinks, there wasn't much she could do to beat it right now. Dang it, what I would give for Shield and Sword right now, but there is one card in my deck that could do it.

"I don't entirely trust your face down card, so I will destroy it using my spell card Night Beam to destroy your face down card," Eito continues, and a laser strikes the face down card destroying it.

Well, that figures, I never can catch a break can I? Leia thinks. "All right fine, I've beaten worse than that."

"Well, since my zombies are still too weak to destroy your Dragons, I'll end my turn with one card face down," Eito finishes.

Leia draws a card. "Now, seeing as how Tefnuit can attack, I'll take advantage of that to get rid of your monsters, I'll place one card face down and attack your Dragon Zombie with Tefnuit, Shining Firestorm!" She commands, and a blazing white ball of fire forms in Tefnuit's mouth, and it incinerates the undead dragon. "Now its your turn Asar, destroy his Clown Zombie with Emerald Inferno!"

The undead shatters again in the green inferno.

"Go trap card, Greedy Ghoul, since Call of the Haunted is active on the field and all three of those monsters where destroyed, I can draw 2 cards, but I have to discard two cards off the top of my deck," Eito says, drawing two cards, and then picking up two more cards and sliding them into his graveyard.

"Well, I end my turn with one card face down, lets see what you can do this time," Leia sys.

(L: 3550) - (E: 4335)

"Then its my turn, and you know what that means," Eito says as his three zombies appear again, but something is different this time. Dragon Zombie's attack has risen to 1760, Armored Zombie's has risen to 1815, and Clown Zombie's has risen to 1633.

"They stack too? Oh you gotta be kidding me," Leia says, she was running out of options fast, but at least Asar would survive, and that might give her an advantage.

"Now, I play the spell card Shrink, so I cut Asar's attack in half," Eito says as Asar's attack falls down to 1300. "Dragon Zombie, attack Asar with Noxious breath attack!"

The undead dragon breathes its foul breath on Asar, but its redirected and hits Nuit, shattering it.

"I tributed Nuit so that Asar survives," Leia says.

"Fine, Clown Zombie, you do the job, Malicious Daggers!" Eito commands, and Clown Zombie takes out daggers, and throws them at Asar, then it hits Tefnuit and it shatters.

"I get the effect of Tefnuit now, I can special summon a monster from my deck, so I special summon a second Hieratic Seal of the Sun Dragon Overlord (0/0)," she says, and a second large spherical monster appears.

"Now, Armored Zombie, lets finish that monster, Dishonored Blade attack!" Eito finishes as the zombie samurai slashes through the dragon, destroying it for good this time. "I'll end my turn there then, I hope it was worth it to take all that damage."

(L: 2209) - (E: 4335)

"We'll see, its my draw!" Leia says, drawing a card, she had to get what she needed right now, or if she didn't, she would lose on her next turn. She looks at the card, and smirks, sliding it into her disk. "I'll set one card face down, and summon my Decoy Dragon (300/200) in attack mode!"

As she says this, a small cute blue scaled dragon appears with a growl.

"This is a joke, right?" Eito asks with a laugh. "I mean seriously, that monster isn't strong enough to destroy mine, it would have been better to just give up."

"Its my move to make, Eito," Leia says, shaking her head. "I'll end my turn there, lets see what you can do now."

"Fine, I draw then," Eito says, drawing a card, he starts to make a move when Leia interrupts him.

"I activate my trap card, Burst Breath, so I sacrifice my Decoy Dragon, and now I can destroy all monsters on the field with less defense points than it has attack points!" Leia counters as Decoy Dragon begins to glow brilliantly, then breathes fire all over the field.

"But... my monsters have no defense points at all!" Eito says shocked as the three zombies shatter along with Hieratic Seal of the Sun Dragon Overlord.

"And, I'll bet anything that Call of the Haunted only brings them back when they're destroyed by battle, not by card effects," Leia says, getting a glare from Eito. "I'll take that as a yes."

"Fine then, I summon my Bone Crusher (1600/200)!" Eito says, and a skeletal warrior with a viking helmet and carrying a stone axe appears."Bone Crusher, attack her directly, Stone Axe Smash!"

The undead warrior smashes its axe through Leia.

"And that's all for my turn, lets see what you can do."

(L: 209) - (E: 4335)

"This, isn't over yet," Leia says, drawing a card quickly. "I play my face down trap card, go Birthright, so I bring back my Hieratic Seal of the Sun Dragon Overlord, and I play Silent Doom, to revive my first one (0/0 x2)," she says, and the two massive spherical monsters appear.

"Ha, those two monsters don't even come close to standing up to Bone Crusher," Eito laughs.

"Yes, but I can use them to summon something that can, I overlay my Hieratic Seal of the Sun Dragon Overlords together, to create the overlay network!" She says, as the vortex appears in front of her, Eito stops laughing. "To Xyz summon, the most powerful monster in my deck, I summon the Hieratic Sun Dragon Overlord of Heliopolis (3000/2400)!"

The monster that appears is a massive red dragon with two wings, it lets out a roar that knocks Bone Crusher back a few inches from the sound wave.

"That's... I don't believe it..." Eito says. "When did you get that card?"

"Yesterday, so thanks for volunteering to be the test subject for the big guy, I activate the effect of Sun Dragon Overlord, I remove an overlay unit..." Leia says, taking one of the two monsters and sliding it into her graveyard. "And I'll discard a card, to destroy your Bone Crusher!"

The dragon swipes at the zombie with its claw, shattering it.

"This duel's not over yet, Kaiba, I can still win this," Eito says.

"Afraid not, I play the spell card, Battled Tuned, and since the card I just discarded was my Magna Drago, I banish it, and I give Hieratic Sun Dragon Overlord of Heliopolis another 1400 attack points!" Leia says as the dragon's attack rises to 4400.

"Mercy..." Eito says.

"Mercy? Lets see... fine, Sun Dragon Overlord, attack him, gently," Leia says as the dragon punches Eito, sending him sprawling.

(L: 209) - (E: 0)

"All right Eito, its over, and you better hope your lawyer can get you out of this again, but I have my doubts," Leia says, removing a jewel from her coat, Eito groans, then vanishes in a flash. "Better get out of here, the dead have ears..."

Leia opens the door to the morgue and walks out, thankfully a friend of her's had agreed to keep anyone from coming down to investigate. Now, it was just a matter of getting back home.

On the outskirts of Seidou was an area set apart for mansions and other homes belonging to the more wealthy inhabitants, this was also where the current incarnation of the Xavier Institute was. Leia goes past the mansion on her sleek silver Duel Runner, pausing for a moment to admire the building, after the original Institute had been demolished years before, the X-Men had done their best to replicate the building when they settled into Seidou.

But that wasn't Leia's final stop, she moves past it and comes to a stop in front of another mansion, the gate opens and she pulls her Runner inside. She parks it and gets off, removing her helmet as she heads inside.

"Leia, did it go okay?" A young man a few years older than Leia asks, he's Japanese with black hair tied in a ponytail, wearing a blue shirt and pants while Leia hangs her coat up.

"Eito's back behind bars, he's probably being processed now, Arashi," Leia says. "You'd think he'd try not to get back in jail."

"Yeah, well some people never learn," Arashi Saito, the senior member of the Shadowchasers in Seidou says. "Did you hear from Marie?"

"Yeah, she got a gig in town, so she'll be out late," Leia says. "And Kaedin had to go to his clan for something, guess its just us tonight, now what's to eat around here, I'm starved."

The Shadowchasers of Seidou had always been good people, I had known every member that came to live in the town ever since I first met Jalal after the end of the Mutant War.

I'll admit, over the years as I learned more about Shadows, I never quite understood everything about them, but I know that they are not something to be trifled with. In some ways, the mission of the Shadowchasers isn't that different from that of the X-Men, but we don't have the advantage of the veil, not anymore.

And as this conflict dragged on, there was pleanty of fear of battle lines being drawn between Mutants and shadows.

And that's chapter 1, I hope you enjoyed it, sorry about the sudden decision to re-write the story, but I figured I could make it better.

Next chapter, who is Marie? Well, if any X-Men fans out there are thinking, no its not Rogue, next chapter we'll meet her. A community of Mutants tends to attract unwanted attention, and not necessarily always from normal humans.

Who has come to Seidou? Find out next time in Chapter 2, "Psychic Jumper: Change is Gonna Come."
