Chapter One: A New Enemy

Flash of lightning appears from the sky as the rain heavily pours in the night. In a forest somewhere in the Land of Fire, the Moya Triad were hoping tree by tree to escape from the rain. They weren't gonna make it to a nearby village in time. So they would have to find a nearby shelter somewhere or make camp. Which would be very impossible to do with the ground really muddy. "Great, we're getting soak and wet." Mo complained. "We can't even find shelter in this forest."

"And the village we're heading for is still a long ways off. We're not gonna make it in time with this storm in our way." Ya said.

"You too settle down. Will find shelter somewhere." Aniki, the leader said,

"Yeah and how we're gonna find it?" Mo asked.

Suddenly, a flare was launched in the air. It light up the forest surprising the brothers. They were in defensive stance, thinking it was an ambush by rouge ninjas. Looking around to see if the enemy was ready to attack. Aniki saw a figure appearing from the darkness. A person wearing a cloak to hide its face, walk towards the brothers. "You looking for shelter?" a male voice asked, almost sound like a robotic tone. "Come with me."

The hooded figure turn around and walk to where he came from. The brothers were looking at one another. Had to make a decision to go with him or just leave. "I have a bad feeling about this. You saw how he just came out of nowhere in the darkness and shot up that flare. It's like he was watching us." Ya said, in a nervous tone.

"Should we trust him?" Mo asked.

Aniki look up to see the flare was about to be dimmed because of the raindrops. It was a tough decision he had to make. "We're gonna have to listen to what he say. He's giving us shelter for the night. We can't say no for an answer. Right now we gotta get of this rain and catch up to him or we're gonna be lost." he said.

The brothers agreed as they hurry to catch up with the hooded man. The flare was now out and darkness return to the forest. They saw the man with a lantern, signaling them to know where he was at. The brothers followed him remain cautious in case of any trap or ambush he was leading them to. It was a silence walk. Only the sound of rain and lightning would be the noise.

The group exit from the forest as they enter a clearing. The brothers notice something on the edge of a hill. A flash of lightning reveal to be an unknown temple with a domed roof on it. It wasn't like an Asian Temple but almost it was never been reveal or seen before.

After the long walk, the group finally enters the temple. Torches and candles on the walls and ceilings to help light the place. The brothers dried themselves with towels. Placing their wet clothes to a nearby wall. The brothers were surprise by the place. The walls and floors were made of metal with grids and glyphs. "Wow, this place is something else. I've never seen anything like it." Mo said.

"Never seen this place before in my life. I wonder if this is forbidden or something. There are other temples on the mop but this one is not on it. I wonder why?" Ya asked.

Suddenly, they heard a sound of a musical instrument being played. The brothers walked toward the location of the sound. They were getting closer where it was getting louder. The brothers walked through a big room. It had four faces statues on the wall. Little bit of raindrops from the ceiling at the middle dropping to the floor.

They saw the hooded man playing some type of flute. The brothers walk towards him. Still have their kunais with them just in case. The figure stop playing the flute to turn around towards them. "You must have heard me with this. I made this flute myself. It's pretty nice." he said.

"Listen, we just want to say thank you." Aniki said. "We of course were trying to get to a nearby town and settle for an inn. But the rain was heavy we were running out of options. Anyway, if its okay will be staying for the night here. The rain should be gone by the morning and will be on our way."

"I see. Yes, the storm won't let up for the time being." the hooded man replied. "But please, don't go to the other rooms that are off limits. You might wake "them" and "her" up."

The brothers were confused by that statement. "What did he mean "them" and "her"? What is he talking about?" Ya asked.

Aniki want it answers from the hooded man. But he was already gone. Disappear out of sight like a magician would do. "I never got a chance to tell him what his name was or show us his face." he said.

"So what are we going to do?" Mo asked.

"Like I said. Will stay here for the night until the rain is gone." Aniki said. "Until then, I guess we can take a look around this place. Should be interesting to find out what this place is."

"Remember what the man said." Ya answer. "We can't go to the rooms that are off limits."

"He should've told us about what rooms he was mentioning about." Mo said.

"Well, either way. Let just be on guard. You never know, temples like these always have traps. Be on guard and let's see what happens." Aniki said.

The brothers plit up as they began examining the temple. But what they didn't know, something hanging on to a metal beam was watching them from above. It snarl at them with saliva drooling from its razor sharp teeth. Quietly, it disappear in the darkness.

Mo enter through a tunnel. Using a nearby torch to see where he was heading. There were other torches on the walls. He kept walking to his destination whatever it was leading him too. He comes across a doorway with weird marking on it. Almost looks like skeletons of a mysterious creatures that he never seen before. The skeleton has a large, curved, oblong head. He touch the markings on the door, only for a hissing sound to surprise him. The doors slowly open. He walks inside the room.

It was pitch black. Despite the torch in his hand, he still couldn't see. Suddenly, the light were coming on by itself. Reveal a room with a little mini waterfall in front of him and a puddle full of water. There were another part of markings of the strange creatures like on the door. He took a sigh of relief, walking over to the puddle. Grabbing it in his hands and splashing to his face. He took another round by drinking the water, which is more pure than any other water. He place another inside where he felt an object in the puddle.

He grabbed the object out of it. Revealing a gray Forehead Protector. The metal plate shows the symbol of Kumogakure aka the Hidden Cloud Village in the Land of Lightning. Mo was even more confused. Why was this protector here? It feels like he and his brothers are not alone here and someone was here before they did. He notice the reflection of the puddle of something above him. He look up with his eyes wide. A woman, unconsciously was wrapped in mysterious black webbing on the ceiling.

"What the hell? Is that a woman?" Mo thought as he jumped in the air and landing on a metal beam. He pulled out one of his kunais, ripping off the webbing which was sticky. Took a couple of seconds to get the webbing off. He grabbed the woman and retreat back to the floor. He grabbed another round of water, placing it inside her mouth to wake her up. He put another round of water in her mouth once again until finally she started coughing.

The woman has long, straight, blonde hair bound with taut bandages. Dressed in a short-sleeved black and purple blouse and black pants, both of which had a design similar to clouds on them, purple fingerless gloves and a chain of blue beads around her left hand. The woman slowly open her dark eyes. It was blurry, trying to get it focus to see. "Are you okay?" she heard a voice as her eyes finally came in focus. She look up to see Mo above her.

"Are you okay?" he asked once again.

The woman regain conscious by surprising him with her arms around his neck. Putting him in a choke hold, she dragged him to the puddle. Placing his head in the water, trying to drown him. But she wasn't gonna kill him. She want it questions by interrogating him. Mo was grasping for air. Bubbles were coming from him on the surface. The woman pulled his head out of the water. He was grasping after that. "What the fuck what that all about?! Is that the thanks for saving me?!" he yelled.

"Shut up!" she replied, grabbing his kunai, putting the tip of the blade near the right side of his head. "All right. You better start giving me questions and I want answers! Who are you? Are you working for that David guy?!"

"What are you talking about? Me and my brothers were here seeking shelter because of the rain! I saw you surrounded by a ton of webbing on the ceiling." Mo answer, still catching his breath with the woman's arm around his neck. "I'm just examining the temple until I saw this room."

"Are you lying to me?!" she asked in her angry tone.

"No I'm not! I'm telling the truth I swear!" he said.

Finally, she unwrap her arm around his neck as Mo was coughing, trying to regain his composure. The woman was looking around for something. She grabbed her sandals and a kunai holster. She was also looking for one more thing. "Looking for this?" she turn around seeing Mo with her forehead protector.

"Thanks." she replied as she grabbed it and placing it back on her forehead, tying it.

"You're from the Land of Lightning. I can tell by the logo on you're protector. What are you doing here in the Land of Fire? How did you get caught?" he asked.

"It's a long story. My squad was ambush. That's was the only thing I can remember. But I know full well it was that David guy that set us up." she replied, getting her kunais ready.

"Wait a minute. You the mean the hooded man's name is David?" Mo asked.

"That's him alright and I'm gonna try to find him and end his life one way or another." she replied. "By the way, you said you have brothers here in this temple?"

"Yeah. We're just splitting up and looking around at this place. I didn't know we're not the only ones here." Mo said.

"My god. He's gonna luring your brothers into a trap. Quick let's find them." she said as they ran to the exit but stopped for a minute. "By the way, my name's Yugito Nii."

"I'm Mo. I know its a stupid name." he said as she chuckle.

"Come on, let's find them." she said as the two departed from the room.

They didn't notice the same figure was above them the whole time. Hearing everything, the mysterious creature disappear in the darkness but follow them.

Ya was in another part of the tunnel. Looking on the metal walls showing the markings of the creatures. Looking where they were eating like humans on it which was a little graphic for him. He continue on forward as he come across a doorway. He put his hand on it, only to flinch when a hissing sound was heard. The door opens slowly where the lights were coming on slowly in the room. His eyes were wide like a deer in a headlights when he came across a disturbing scene.

The room was full of black webbing from the ceiling to the walls. There were multiple eggs everywhere. Some were already hatched from the top of them. But the disturbing part that almost made Ya vomit. Bodies of dead Shinobis were pinned to the walls by the webbing. There were big holes on their chest with their blood everywhere in the room. It was like something came out from their chest.

He gotten closer to examiing the bodies. He look at the symbol on their forehead protector. It shows the logo of Kirigakure. These Shinobis were from the Land of Water. "These people came from the Land of Water. How in the world they came all the way to the Land of Fire? What was they doing here?" Ya thought.

"...Help… me..." Mo flinched when he heard a slow voice. Looking around for the source of the voice. He already knows it ain't from the Kiri Shinobis on the wall because they're dead. He look back at the eggs, not want to touch them. No telling what would happen. "Help…. me..." the voice was there again. He was getting nervous. Feels a ghost was here in the room. Suddenly, a water drop hit him on the forehead. Causing him to look up, he saw a young wrapped in black webbing. His eyes were opening, blinking signaling he was still alive.

Ya leaped in the air, landing on a metal beam. He quickly pulled out his kunai, ripping all the webbing. He grabbed the young man and landed back on the ground. The man went on his knees, breathing enough oxygen from his lungs. The man has short, messy, grey hair which fell over the right side of his face and spiked up on the left. His eyes were pink, pupiless with a stitch-like scar running from under his left eye, all the way down the cheek. "Are you okay?" Ya asked.

What they didn't notice, one of the eggs behind them was opening from the top. Something inside the egg was moving and ready to escape from it.

The young man wore a grey, sleeveless shirt with the Kirigakure Forehead Protector attached to the front, short-sleeved mesh armour over which he wore a green poncho. He also wore a turquoise sash around his waist, paired with a matching green apron over his pants. The man look up to his savior. "Thank you for saving me." he said.

"You're welcome. Its a good thing I heard your voice. I was about to leave this place and give up. Thinking I was hearing things." Ya said. "What's you're name by the way?"

"Yagura Karatachi. The Former Fourth Mizukage of Kirigakure from the Land of Water." He introduced himself.

"I'm Ya. Its nice to me-" he stopped for a minute when he realized his jaw dropped. "Wait a minute. Did you just said you were a Mizukage?"

"Yep." Yagura answered with a smile.

Ya examining him everywhere. "Are you sure? You're really look like a pipsqueak that is too young to be a Mizukage?" he asked.

That set off Yagura. He grabbed his club and whack Ya on the head. Which call him to get a big bump on his head. "Idiot! Say pipsqueak again I dare you!" he said in an Anime Anger style.

"Really? This is the thanks I get for saving you?" Ya asked, rubbing his bump. "Anyway, what are you doing here especially for the Mizukage to be here?"

"Maybe I can ask you the same thing." the former Mizukage replied.

"My brothers and I were on our way to another town but the storm was getting heavy." Ya explained. "We try to find shelter somewhere until a hooded man came out of nowhere in offering shelter for us. That's where we came across this temple."

"Wish you guys should've say no. Because his lured you and your brothers into a trap. He did the same thing to me and the rest of my squad." Yagura pointed his finger to where the Kiri Shinobis were on the walls. "And I'm not the only one, a girl named Yugato has been captured here as well. But we have to hurry and find your brothers and the girl before its too late. We must warn everyone about what's he planning."

"What are you talking?" Ya asked.

"I'll tell you more later. Let's get of this room of-" Yagura stopped when he sense something. Turning around, he notice one of the eggs open in front of Ya. "LOOK OUT!"

Suddenly, a spider like creature burst from the top of the egg onto Ya's face. It tighten its six legs on both sides of the head. Its tail tied really hard on his neck. He falls to the ground, fighting hard by using his hands to try pry off the creature from his face. Screaming almost losing breath, Yagura ran up to him. Pulling out his kunai by cutting the creature, with blood gushing out.

The Former Mizukage started to scream in pain. Some of the blood splash on his left arm, grabbing his right hand to cover it. He hear the hissing and bubbling sound on his left arm. The creature's blood is highly acidic. Gritting his teeth because of the pain, he tries to take it but it was to strong to handle. He grabbed the kunai to cut the creature until its death. He grabbed the creature off of Ya's face, throwing it to the side. "Are you okay?" he asked, seeing him freaked out.

"Son of a bitch! What the hell what that?" he was freaked out but Yagura slapped him to get him controlled. "I needed that. But what was that came on my face?"

"Looks like one of those that came out from the eggs." Yagura answered.

"I don't know about you but we better get the hell out of-" he was interrupted by something crawling on the wall, slowly that was behind Yagura. He pointed his finger to where it was, trying to warn the former Mizukage. "L-L-Look out… b-b-b-behind you."

Yagura heard a snarl from behind him. He slowly turn around as he eyes were wide as hell. His heart was beating at a rapid pace. The two saw a creature that is a humanoid type but was different. It had an elongated, cylindrical skull but possess no visible eyes and had segmented, blade-tipped tail. The tail have a flat ridge of spines at the base of the blade. Its razor sharp teeth, dripping saliva, ready to feed for some flesh.

"Oh shit." the former Mizukage said.

The creature roar as it charges towards the two.

Aniki enter a room where the light automatically turn on. Looking around, he saw drawings of strange creatures. He grabbed one of the drawings to examine them. "I never seen these kind of creatures before? What in the hell does this man knows about them?" he thought as he referred to the hooded man. He continues to examine the other drawings around the room. He notice on the table a map of the whole continent including the Five Great Countries. They were x marks on the map, marking all villages around the continent. It also show arrows directing towards the villages. "What this person been doing? Is this like some kind of an attack plan?"

"I see you stumble across my room. Which I told you not to enter." Aniki turn around seeing the hooded man at the entrance.

"All right, I want answers from you." the elder brother replied. "What the hell is all these drawings of strange creatures? Plus, I found this map of the Five Great Countries. What's with all these X's and arrows pointing towards every village including the main villages? Its like you're planning some kind of an attack."

The hooded man slowly walked towards Aniki as the elder brother slowly move his arm towards his kunai pouch, ready for any attack he would do. "Something that needs to be accomplished. Something that a new world that can be created by "her" to roam the face of this planet. Something that can be rid of this human infestation. Something that can give peace to this world." he explained like a poem he was reading.

"Who is "her"? What the hell are you talking about?" he asked, trying to get more information.

The hooded man stood face to face with Aniki. He took the cloak off of his head to reveal his face. The two stood there staring at one another for seconds. "I would love to tell you about "her"… but..." David lean in to his right ear. "You won't witness that moment." He surprise him by stabbing Aniki to the left side of his stomach.

The elder brother felt the blade enter his flesh for seconds when David pulled out the blade. Aniki falls to the ground. Sitting up, putting pressure on the wound with both hands. He tried to get the kunai from the ground, only for David to kick it to the side. Aniki was running out of options as David walk up to him, ready to end his life. "Don't worry about your body. Because once you're dead," he raised the knife towards him. "She would feast upon your flesh."

Aniki closed his eyes as David was about to go for the final strike. Suddenly, a kunai came out of nowhere, hitting the knife away from David's hand. The two look around seeing Yugito with an angry glare towards him. Mo was right behind her as he saw Aniki sitting up. "Shit, brother!" he ran up to get his brother on his feet.

"How in the world you escape?" David asked.

"That's none of you're concern." The Kumo Jonin said as her nails grow longer. Still, looking towards David with anger. "You killed the rest of my squad. A monster like you thinking you're God. I know full well you're planning on capturing my Tailed-Beast to use it for power. I'm not gonna let that happen."

"You really are that smart. But don't worry, I'll see through the Land of Lightning will be taken down by me real soon. But you won't be part of that once you'll dead." he replied.

"DAMN YOU! CLAW CREATION JUTSU!" Yugito charges towards the humanoid, going for a quick kill with her long nails. But David dodges her attack. He answer back with a kick to her groin, sending her backwards to the wall. She look towards the brothers. "Find your brother and Yagura and get the hell out of here! I'll deal with this monster myself!" the brothers quickly exit from the room.

David grabbed her from the ponytail, throwing her out of the room, flying her towards one of the face statues. She landed on the ground in pain, trying to get back up. David kicked her in the groin once again. She did a quick teleport from the ground. She was in the air, going for another strike with her Flying Claw. The humanoid dodges the attack like before but she answers with a kick to the stomach, sending him backwards to the wall. The Jonin tries to go for another strike where David dodges her attack. He grabbed her by the arm, kicking her to the ground.

Mo carried Aniki in the room where they saw the fight going on. David saw the brothers. "So it appears you haven't leave yet. Good. Maybe I can give you a chance to see death." he snapped his fingers where they heard multiple loud clawing sounds scaling on the walls above the ceiling. They heard the sound of roaring as well. Three figures drop down, surrounding the brothers.

"What the hell are those?" Mo asked.

The creatures slowly rose up on their feet. They were taller than ever. Looking at the brothers, snarling at them. Dripping saliva from their mouths. Ready to feed to flesh from them. The brothers were horrified they never seen these type of creatures before. Except for Aniki, who saw the drawings in the room thinking their were just art. But they were real. "Say hello to my creations. The Xenomorph Warriors." David answered.

"Holy shit. We're fucked." Mo said, frighten by the creatures.

"Don't worry, they won't bite… unless you make them angry like they are right now." David answered in a taunting way.

"What we're gonna to do?" Mo asked but no answer from his elder brother, who only afraid of his life.

"I guess will make this quick." David said, ready to snap his fingers.

"LEAPING BULLET SHELL TOWER!" Yagura surprised everyone by curling himself into a ball, crashing in the middle of the room. The Warriors quickly dodges the attack by moving onto the wall. The former Mizukage appears in the room with his club. "Yugito!" he ran up to the Kumo Jonin. "Are you okay?" he asked.

"I'm fine. Its about time you showed up." she said as he help her on her feet.

"Guys, are you okay?" Ya asked as he saw the wound on Aniki's stomach. "What happened to you?"

"That son of a bitch stabbed me." the elder brother pointed his finger at David. "I'm sorry, guys. I should've listen to the two of you. Full well he couldn't be trusted."

"So the former Mizukage has also escaped. Never thought the two of you would escape thanks to the help of those fools. No matter, since you all here. I guess you can join the face of death." the humanoid.

"I'm not gonna forgive you for you did to my squad. I'm a person that hold grudges to my enemies. You, are one of them. Now you're feel what you did to us." he said. "Ready, Yugito?"

"I'm always ready." she replied.

The two closed their eyes where light was surrounding their bodies. Suddenly, two large mysterious creatures came from behind them. Behind Yagura, a beast resembles a large turtle, but with a crab-like shell, spikes all over its body, and three shrimp-like tails. Under its shell, it has red, muscle-like tissues. It has a pair a human-like arms and hands, but no hind-legs. His face is concealed between a large forhead and lower jaw – both of which have spikes. Its eyes are red and have crimson pupils.

Behind Yugito, a two-tailed, like a bakeneko, and its completely engulfed in flames, like a Kasha. It also has heterochomatic eyes, the right being yellow and the left being green, similar to an odd-eyed cat without pupils. "You called us?" Matatabi asked.

"What is it, Yagura?" Isobu asked.

David saw a glimpse of two Tailed Beasts. "So the stories are true. They are for real after all." he said.

"Hope you like what you're gonna get. Our beasts can wipe out you're enemy so much, you're gonna regret everything you've done." Yugito said.

The Moya Triad were shocked to see how big the creatures were. They have heard stories about the Tailed Beast which they are thought it was a myth. But now, the stories were indeed true. Yagura turn to the brothers. "You three, you better get out of here while you still can. Get to Konoha and warn everyone what's been going on." the former Mizukage said.

"What about the two of you?" Aniki asked.

"Will be fine. Will make sure we put an end to this once and for all." Yugito said. "Besides, its you we're concered. The more blood you lost, you'll gonna die. You must get that patch up if you want to live." she was referring to the wound on Aniki's stomach by David.

"You better go now before he goes after you. You must hurry!" Yugara said.

The brothers were worried for the two but understand the situation they were in. "Will be praying for you get out safely." Aniki said.

"Go now!" Yugito said as the brothers exit from the room.

"So these are the Tailed Beast. How interesting." David said, not surprise by the size of the beasts. "Now then, I guess we want to fight with size of strength. I guess its time we finally wake "he" up." He snapped his fingers where the lights behind him turn on automatically.

The lights show a huge door behind the humanoid. A loud hiss causing the door to open slowly. Suddenly, they heard a loud roar from behind. One by one, large footsteps were approaching the doorway where it opens. Yugara and Yugito got in defensive stance as their beasts were ready for anything it comes out. The doors were fully open and they were stunned of what they were seeing.

It was a large type of Xenomorph. It large head and large arms and legs. Its barbed tail was even longer and bigger. It can ripped up any human flesh in one second. Its razor sharp teethes, dripping saliva on the floor. Other Warrors appears from the doorway, also want to get in on the fight. It was right behind David. "I give you… the Rogue Xenomorph. Of course you can call it… the Xenomorph King." he said.

The Rouge roared really loud at its enemies, echoing almost all over the planet. Yugara and Yugito were horrified by the creation. Even Matatabi and Isobu were stunned by it as well. They were indeed had a fight on their hands to deal with.

Outside, the storm was long gone. The full moon bright up the night sky. The Moya Triad look back at the temple where they heard the loud roar. They were at the edge of the forest. It was a nightmare they would never forget. "Pray for them get out safely." Mo said.

"Come on, we better get to the village fast as possible." Ya said as they enter the forest. Not looking back at the temple.

It was just the beginning of a new danger that was lurking in the continent. Nobody doesn't know what awaits the countries. But it was sure, a nightmare was coming soon that will plague the planet to the darkness.

End of Chapter One

Author's Note: Hope everyone enjoyed that chapter. At first I didn't want alien characters from the Alien Franchise but I decided to go with David as the antagonist for this story. Though there will be more antagonist from the Naruto Universe to be part of David's chance of conquering the world. You'll find out who that is later on in the story.

As mention, this will be a Harem Story. I'm planning on making some chapters with Yuri Lemon scenes since the girls I chosen to be in Naruto's Harem. You'll be seeing that later on in the story. Plus, I might add the characters from the Filter arcs of Shippuden in this story.

I'm gonna try to not get to all the shocking moments and other cliffhangers quick as possible. I want to built this up leading to all the events moving forward.

Well that's all I can say. The next chapter should be coming this week. I'll be off of work throughout the week because of the Holidays. So it gives me enough time to get the next chapter up soon. Have a Happy New Year and I'll see ya soon.

Review please
