AN: So, I've decided to expand my portfolio by making an X-Men/ Fairy Tail crossover. I plan on writing this story as well as my current Ben 10/ Fairy Tail crossover. So, updates on both stories might take a while, but bear with me.

Now, the adventure begins!

X-Tail

Ch 1: A Demon Emerges

Part 1

Xavier Institute 7:00 PM

It was a quiet night at the Xavier Institute and things seemed to be rather slow. Cyclops and Jean were off on a second honeymoon, Logan and Remy were busy pushing their bodies to the limit in the Danger Room, Jubilee, Rouge, and Storm were busy having a girl's night out, and Hank and Morph were busy in the lab. This left a certain 19-year-old mutant alone in his room, watching TV.

He had blue hair, blue fur, yellow eyes, a pair of fangs, and a devil-like tail. He was about 6 ft tall and he had three fingers on each hand and three toes on each foot. He wore a black bodysuit with a red V-neck design on his chest and an X-Men symbol on his chest in red. This was Kurt Wagner, better known as, Nightcrawler, the teleporting mutant. He'd recently joined the X-Men and was eager to prove himself after the whole church incident where he met Logan, Rogue, and Remy.

Despite his devilish appearance, Kurt is actually a devout Catholic. After his encounter with the X-Men in the church and the revelation of his mother being Mystique, Kurt traveled to live his own life. However, the constant persecution caused him to realize that he should be helping people better understand Mutants. So, after some time had passed, he decided to join the X-Men after Charles Xavier had left the Earth for medical treatment.

Unfortunately, it's been a whole year since Xavier left, and still no word on his condition. This caused the X-Men to inevitably drift further and further apart to the point that they didn't even train together anymore. They were still a fighting force for Mutant's rights, but Kurt lived in fear of Professor X's dream dying. While he never met the man, he idolized his ideals. However all of this uncertainty was soon about to change with one phone call.

The phone had rung in the living room and Kurt eagerly teleported to where it was in a puff of blue smoke.

"Guten tag." Kurt said as he answered the phone.

"Kurt, come down to the lab, its important." Hank replied.

Without a word, Kurt hung up the phone and teleported to the lab.

'This is going to be fun.' Kurt happily thought to himself.

Xavier Institute Laboratory 7:05 PM

Kurt had easily teleported to the lab and eagerly greeted Beast and Morph. The lab itself was huge with numerous machines and devices.

"Not that I'm complaining, but what's so important Hank?" Kurt said.

He directed his question towards a giant of man. He had blue fur and skin like Kurt, but he was much more muscular, he had blue eyes, and he resembled a gorilla in stature. He was wearing a white lab coat and glasses, patiently reading a book, waiting for Kurt to arrive. This was Dr. Hank McCoy, better known as, The Beast, the mutant powerhouse and genius of the X-Men.

The man next to him appeared to be in his 30's with brown hair and brown eyes. He was wearing a brown trench coat and underneath it was a black body-suit with a gold trim and an 'X' belt buckle. This was Morph, the resident Mutant shape shifter of the X-Men.

"I'm glad you came so soon Kurt. I have something very important to show you." Hank said as he led Kurt further into the lab.

"Should I come too?" Morph asked timidly. Ordinarily, Morph would've followed without hesitation, but he was still a little messed up after the Sentinel mission and his forced betrayal of the X-Men, regardless of his countless hours of therapy.

"I wouldn't have it any other way Kevin." Hank replied as he continued walking.

The trio moved further into the lab until they came across 10 strange devices on the table they had stopped at. The devices were shaped like backpacks, only far more technological than anything Kurt had ever seen before. They were silver in color and each one had the X-Men symbol stamped on the left strap.

"What are these things?" Kurt asked Hank.

"These are Mutant Amplifiers. They're meant to increase a Mutant's powers exponentially to the point they could become Omega-Class." Hank explained.

"Omega-Klasse!? That's the strongest level on Earth!" Kurt yelled in surprise.

"So, these things can make me look like anyone else even better than I already can?" Morph asked.

"Yes. In theory. They still haven't been tested yet." Hank explained.

"So, is that why you asked me here?" Kurt asked. Hank replied with a simple nod.

"But what about me? I'm willing to help too you know!" Morph said incredulously.

"Given your experience with technology Morph, I felt it best to have Kurt test it out first." Hank replied.

"I'm not going to break down again Hank." Morph said stoically.

"Maybe, maybe not. In any case, Kurt will test it out first, and if it's a success, we'll try it out on you." Hank said.

"Okay, but how am I supposed to carry a 50 lb backpack?" Kurt asked.

"It might look heavy, but it's actually made from materials and schematics the Shi'ar gave me. They're no heavier than a feather." Hank replied with a hint of smugness.

"Yeah, except those bird brains still won't tell us what happened to Chucky." Morph said angrily.

"Now Morph, be reasonable. Charles will return. We just need to be patient." Hank said with a small twinge of uncertainty.

While he did his best to take Charles's place, Hank could never reach the X-Men the way that Charles could. He once thought about handing over the Institute to Cyclops or Jean, but they were too different now. Nevertheless, Hank was fighting a long battle, and losing.

Wanting to quell the tension in the air, Kurt lifted up one of the amplifiers with ease and strapped it on. Much to his surprise, the backpack had shrunk to fit his back perfectly.

"So, how does this thing affect my powers? I don't feel anything." Kurt asked Hank.

"All that you need to do is use your powers when you have it on, and you'll be able to teleport anywhere in the world." Hank explained, relieved that the talk was over.

Kurt eagerly grinned with anticipation as he began to activate his powers and disappeared in a cloud of blue smoke, or so he thought. The smoke appeared, but he was still in the lab, much to his confusion.

"Shouldn't I be somewhere else right now?" Kurt confusedly asked Hank.

Hank had gasped in shock that the experiment had appeared to be a failure. The feeling of shock was soon replaced by one of horror as Kurt's body began to glow yellow and the Mutant Amplifier began to spark electricity in all directions. Hank and Morph were absolutely terrified of what they were seeing. They desperately tried to pry off the Mutant Amplifier, but they couldn't even get close enough to reach it.

The electricity had formed a protective cage around Kurt as he desperately tried to escape. He tried to pry off the Mutant Amplifier by himself, but to no avail. His body had become engulfed in pain as he pounded on the electric cage. He couldn't even teleport away from the Institute. That option became null and void as Kurt's body had glowed an even brighter shade of yellow and with one final scream, Kurt disappeared. The only thing left behind was a badly burnt and broken Mutant Amplifier.

"Hank, what just happened to Kurt?" Morph fearfully asked.

Hank had been busy reading the instruments in his lab in an attempt to find Kurt, however, he couldn't seem to locate his X-Men symbol anywhere on Earth. Hank even tried using Cerebro to find him, but he came up empty.

"Hank, is Kurt…dead?" Morph asked.

"No! There's no signs of disintegration where he disappeared. He's definitely alive, but I don't think he's on our Earth." Hank replied.

"What? You mean he's on some alien world somewhere?" Morph asked incredulously.

"No. Cerebro is locked on to all active X-Men signatures. If Kurt was on another planet, Cerebro would've sensed it. I have a rather unpleasant theory on his whereabouts." Hank solemnly replied.

"What kind of theory?" Morph asked.

"I'm afraid that Kurt...is in another universe." Hank replied.

"That's crazy! Have you been hanging around with Deadpool?!" Morph said in disbelief.

"It's not exactly impossible. Kurt's powers enable him to move from a pocket dimension to anywhere else in the world. Maybe the Mutant Amplifier increased his power's range to the point that he actually accessed another universe." Hank explained.

"And I take it you have no idea which one…right?" Morph sarcastically asked.

"Sadly no. I don't know if we can even save him. I'll work on it in the lab 24/7, but in the meantime, console the others. Kurt might be gone for a very long time." Hank said as he walked silently back to the lab.

'Kurt, wherever you are, I hope you are okay.' Hank thought to himself as the lab doors closed.

East Forest 8:00 AM

Kurt had awoken in a strange forest and was currently lying on his back, disoriented and in pain.

'Wo bin ich?' Kurt thought to himself as he shakily stood up with his hand on his knees.

Not knowing exactly where he was, Kurt stumbled in a random direction and just kept walking.

'What is this place? My head is beating like a bongo drum and I don't feel like I'm somewhere familiar. It's like I don't belong here.' Kurt thought to himself.

Before he could inquire further, he saw a giant shadow looming over him and came face-to face with a 20ft tall ape-like creature with green fur, soulless eyes, and a really bad temper.

"I don't suppose you're friendly?" Kurt nervously asked.

"You are not human. Regardless, I bet you taste delicious!" the creature roared as it lunged a powerful right hook into Nightcrawler's chest. He would've been able to avoid that, but in his current state, he didn't have the strength to fight back.

He painfully crashed into a tree, spitting up a little bit of blood in the process. Strangely, when this happened, he felt an intense wave of pain. He tried getting up, but the ape-like creature kept punching him, making a large indent in the tree. Nightcrawler's body was in serious pain, but the creature never let up. Each punch was stronger than the last, and Nightcrawler was reaching his limit.

Before he passed out from the pain, the creature stopped attacking and examined his body. His arms were broken, his chest was horribly bruised, and his legs were twisted. In short, Nightcrawler had seen better days. However, his peace didn't last very long as the creature began to laugh maniacally.

"Pathetic creature! You broke so easily under the might of a Vulcan. You've been tenderized enough. It's time for the main course!" the Vulcan said as it hungrily approached the thoroughly beaten up Kurt Wagner.

'I can't move and I can't teleport away. I can't believe I'm going to die like this. Please forgive me lord.' Kurt solemnly thought to himself as he awaited death.

The Vulcan's lips were smacking and he was drooling in anticipation as he moved in closer to his prey. He opened his maw and Kurt silently prayed to God as he awaited his fate. Suddenly, the Vulcan was attacked out of nowhere by a young boy with his fist on fire.

He had spiky, pink hair, a black waistcoat with a gold trim, a peculiar white scarf, and knee-length white trousers. He had gray eyes, black sandals, and a strange symbol on his right shoulder in red. This was Natsu Dragneel, Fairy Tail's Fire Dragon Slayer, better known as, Salamander.

"Okay monkey brains, this guy's not on the menu!" Natsu declared as he engaged in a stand-off with the Vulcan.

"Pathetic human! You think you can beat me?!" the Vulcan angrily declared.

"I don't think, I know!" Natsu declared as his cheeks began to puff up beyond human limits.

"FIRE DRAGON ROAR!" Natsu yelled as a huge torrent of fire came from his mouth.

'He's a mutant! Maybe he'll help me.' Nightcrawler thought to himself.

The torrent of fire hit the Vulcan and it badly burned the surrounding areas, leaving the forest that had gotten hit to be burned and charred. This went on for several seconds before the flames died out, leaving only a badly wounded Nightcrawler and a catatonic Vulcan in its wake.

The Vulcan was badly burned to the point that all of his fur had disappeared. His body was in immense pain and he couldn't even speak. The only sounds he could make were pained groans as he collapsed forward and slipped into unconsciousness.

After making sure the Vulcan was down for the count, Natsu managed to grab Nightcrawler and gently carried him bridal style to somewhere he knew he could receive medical attention.

"Thank you." Nightcrawler said as he succumbed to his wounds and fell asleep in his arms.

AN: And so the adventure begins. So, Nightcrawler is going to join Fairy Tail and he will be paired up with Erza. It will happen, just be patient. So, rate and review, and I'll be back with an update as soon as I can. Also, the German translations in order are 1. Good day, 2. Omega Class, and 3. Where am I?
