"Naruto vs. Super Sentai"

Chapter 1: "Return of the Killer King"

Disclaimer: Naruto belongs to Masashi Kishimoto, Shonen Jump, and Viz. Super Sentai and its associated characters belong to Toei and TV Asahi. I make no money from the use of either property, nor do I derive any other profit from this story.

Author's note: Sudden burst of inspiration hit me to do this story. To make a long story short, Dr. Mikoto Nakadai – Abarekiller – is one of the most badass "Sixth Ranger" characters to come out of Sentai in a while. Granted, he's dead now, but my idea is that he was reincarnated in the Naruto world as none other than Naruto Uzumaki, and the circumstances of the Land of Waves mission will cause him to awaken his Dino Guts – the power that fuels all the Abaranger – once again. Have fun reading this, I hope.

A blond boy, no older than fourteen, in an orange jumpsuit with blue highlights on the shoulders and a white collar ran up the trunk of a tree, holding a kunai in his hand. As he ran up, he felt himself begin to slip and slashed the trunk with his kunai at the point where he'd begun to slip before he fell to the ground.

As it was, that wasn't the only mark the boy had left on the tree trunk with his kunai. Similar marks riddled the trunk at a certain height, one just ahead of the other. It was progress, but not enough as far as the boy was concerned. If he didn't get even better, the other one would still surpass him, and he couldn't have that.

As it turned out, something had fallen out of the particular tree he had chosen to practice with. It resembled a large white dinosaur egg, albeit with black markings and red "veins." Next to it was a strange white bracelet designed to resemble the profile of a pterosaur's head.

The boy turned his head to look at the strange things that had fallen out of "his" tree. "What the heck?" He didn't know why, but something in him wanted him to pick up the bracelet, and so he did. The moment he strapped it onto his wrist, something happened – namely, a jolt of agonizing power surging through his body.

"AAAAAAAHHHHH!" What's happening to me?! Is this thing trying to kill me?!

The power continued to surge through him, burning away his clothes and replacing them with a skintight armor-like white suit. Black claw marks ran down the sides and outer legs of the suit, and along the insides of the arms. Short white gloves with black triangle pads on the backs and gold-and-black cuffs covered his hands. A gold belt with a buckle shaped like a cracked egg with three spikes protruding from the top and one spike from the bottom wrapped around his waist.

A white breastplate styled vaguely like a pterosaur covered his upper torso, with black claw marks decorating his shoulders and gold trim around the edges. A white helmet with a small black fin rising from the forehead and red eyes on either side of it covered his head. A red visor that almost could have passed for an X if not for the triangular dip in the lower side shielded his eyes.

The boy breathed heavily, unsure of just what had happened to him, but knowing that he felt stronger than he'd ever been before. Just as suddenly as it had come, the strange power retreated, taking the suit with it and leaving him back in his orange clothes . . . and too drained to do anything but collapse into a deep slumber.

This boy was Naruto Uzumaki, newly minted genin of Konohagakure, the Village Hidden Amongst the Leaves. Naruto Uzumaki, a living sacrifice damned to imprison the monstrous Nine-Tailed Fox within his own body so that his village would be spared its wrath. Naruto Uzumaki, whose father's final wish had been for him to be seen as a hero for his sacrifice, but who had only met scorn instead.

And now Naruto Uzumaki . . . Abarekiller once again.

When he woke, he felt like a stranger to his own body. His limbs felt longer, stronger, and tougher, as did his entire body. His clothes, which normally fit loosely on him, were now uncomfortably tight on his body. The really strange thing, though, was this girl in a rose-colored kimono with a black choker around her neck, and the prettiest brown eyes and long luxurious black hair he'd ever seen on a girl.

"Who . . . who are you?" Naruto asked, his voice sounding strange to him, too.

"I'm just looking for herbs," the girl answered, in a soft, melodious voice.

"Herbs?" Naruto echoed.

"Yes," the girl replied. "Are you all right? I saw you lying out here unconscious and I thought something might have happened to you."

"Nah, I was just training all night," Naruto replied. He felt no need to tell the girl about what had happened last night; he was almost sure it was just some weird dream, anyways. Only in weird superhero shows with flashy effects did strange devices transform not-quite-ordinary boys into supermen of justice.

"Training? Why?" the girl asked. "You seem pretty strong already."

"I need to get stronger," Naruto answered, his voice unnaturally low and serious. "I need to get strong enough so that I can be respected in my village, so that he can look at me and know that I'm just as good as he is."

"And is this person you speak of the one you want to get strong for?" the girl wondered.

"What do you mean?"

"Is he important to you? Do you find him important enough to fight for?"

Naruto stared. "You're not making any sense."

"People become strong, truly strong, when they have something they would give anything to protect," the girl replied. "Do you understand now?"

Memories flashed in Naruto's mind. One was of his sensei Kakashi Hatake's pledge to protect him and his teammates Sasuke Uchiha and Sakura Haruno. Another was of Iruka, his teacher back at the Academy, risking his own life to save Naruto from Mizuki, who had gone renegade. Other memories rose to the surface, of a little girl turned young woman in white, of four young people in red, blue, yellow, and black jackets – and then in skintight red, blue, yellow, and black costumes.

Where did those come from? Naruto thought. Ok, stop watching the kiddie superhero shows; they're not good for you. He looked back up at the girl and said, "I . . . understand."

"Good. You'll become very strong soon." She stood up and turned to leave. "We'll meet again sometime." She began to walk away, slowing down to say one more thing to Naruto. "By the way, I'm a boy."

Naruto's eyes widened. That has got to be the purest load of garbage I have ever heard, a smooth, deep voice spoke in his mind. No way could someone that beautiful be a boy.

Without thinking, Naruto added, Yeah! He's prettier than Sakura! Then something snapped in his brain. Who the hell are you? And what are you doing in my head?

I'm you, the voice answered. The you that once was.

That doesn't answer my question one damn bit! Naruto yelled.

Look at your left arm and you'll find your answer, the voice stated coolly.

Naruto did as the voice instructed and found the white pterosaur-styled bracelet around his left wrist. What is this? Who are you?!

Dr. Mikoto Nakadai, the voice answered. You may call me Nakadai-sensei or Abarekiller.

"So it wasn't a dream last night . . ." Naruto murmured. He looked around, finding the strange white egg that he'd seen last night. "What's this?"

TopGaler's egg, Mikoto replied. He's going to live again, but he's going to need a lot of energy to do it. You'll help with that.

What makes you think I'll help you do that? And what the hell is TopGaler, anyway?

My partner. My Bakuryu.

Bakuryu? Naruto repeated. What's that?

It's too tiresome to explain. Search my memories. You'll know what I'm talking about soon enough.

Naruto closed his eyes for a moment, and saw flashes of giant biomechanical dinosaurs fighting each other, piloted by people in colorful skintight costumes, and even combining at the will of those same costumed people into what could only be described as "giant humanoid machines."

How did you come to be inside me?

I'm not "inside" you; I am you. You as you once were. I am the life that you used to have, before we sacrificed it for the sake of the friends that we had made, the friends that embraced us even after all we'd done to them.

Other memories began to awaken within Naruto, of his former self fighting the colorfully clad people with the power of his own armor – the Zero suit, the prototype for the suits used by the colorfully clad people, the Abarangers. Again and again, he had fought them. Again and again, he had used the Zero suit, despite the destruction its instability could cause over prolonged use.

What kind of monster was I? Naruto thought.

Even that, I do not know, Mikoto answered. We were either a monster of our own making, or the making of the monster inside of us, the monster that nearly swallowed us whole. But we denied him his prize. Our friends denied him his prize. And I suppose . . . this is either redemption or punishment.

Just then, a dark-haired boy in a wide-collared blue shirt and khaki shorts came up to him. Sasuke Uchiha, prodigy of Konoha, heartthrob of all the girls in his age group, last of the formerly proud Uchiha clan, and generally unpleasant bastard.

"Loser," he grumbled. "What are you doing out here by yourself, anyway?"

"Just training," Naruto answered.

"Anyway, we'd better get you back. Everyone's worried about you," Sasuke remarked.

"Does that include you, bastard?" Naruto asked.

"No," Sasuke replied. "Even you wouldn't get yourself killed out here."

"Thanks," Naruto muttered, heading back to Tazuna's house with Sasuke.

While the sun was still out, Naruto continued practicing with tree-walking, although for some strange reason he found it easier than before. Before, it was like trying to climb a mountain without gear. Now, it was no different than walking up a simple ramp. He laughed to himself as he walked all the way up to the highest branch of the tree.

"Hey!" he shouted, catching the attention of Sakura and Kakashi.

"Naruto!" Sakura exclaimed. "You went that high?!"

"Yeah!" Naruto shouted. "I dare Sasuke to top that!"

Sakura growled with irritation, only to gasp when Naruto started to fall. "Oh, crap . . ." Kakashi muttered.

As it turned out, it was just a prank Naruto was playing on them, as he stood upside down on a lower branch. "Just messing with you."

"Naruto, you idiot!" Sakura yelled.

Naruto just moved back onto the tree trunk and ran down on it, flipping off it and landing on his feet in a crouch when he was low enough. "What do you think, Kakashi-sensei?"

"Not bad at all, Naruto," Kakashi remarked. "You're progressing quite well. And did you have a growth spurt, by any chance?"

"Something like that," Naruto answered.

Of course, that provoked Sasuke to almost miss dinner later that night trying to match Naruto's accomplishment. Naruto also nearly missed dinner, primarily from pushing himself to maintain his newfound skills. Then Kakashi had to take a brief diversion from dinner to help Naruto find new clothes, since his old ones were now too small and . . . he frankly didn't trust Naruto's fashion sense one damn bit.

By the time they all got back to Tazuna's house for dinner, Sakura looked stunned at the "new" Naruto. Had he grown taller? And what was he doing in those clothes? Specifically, he was wearing a white-trimmed black jacket partially unzipped to expose a white T-shirt, black pants with orange stripes down the sides, and white open-toed ninja boots. He bore the identifying metal of Konoha on a black headband and his shuriken and kunai pouches were black as well.

"I'm glad you're all back," Tsunami remarked. She smiled at Naruto. "And don't you look handsome?"

"Thanks," Naruto answered. "Kakashi-sensei helped pick these out."

That was technically the truth, but he was holding back a huge part of it. Specifically, that Mikoto had wanted Naruto to wear his battle colors – white and black. Naruto had to admit, he looked cool in them, but he still liked orange, hence the pants.

"Where did you get those clothes from?" Sakura asked.

"Kakashi-sensei helped me with them," Naruto replied. "They were actually tailored for me."

"Seriously?!" Sakura exclaimed. "You had time to buy clothes!?"

"Sakura, Naruto had a growth spurt," Kakashi explained calmly. "And thus he needed new clothes. It wouldn't be a good idea for him to fight in uncomfortable clothes; they could hinder his movements and make it likelier for someone to kill him."

Sakura fumed, but admitted internally that Kakashi was right. "How did you do, Sasuke?"

"Fine," Sasuke replied nonchalantly. "Made it to the top."

As Kakashi, Naruto, and Sasuke sat down to eat, Tazuna asked, "So what made you stick around?"

"It's simple," Kakashi answered. "Evil triumphs when good people stand by and do nothing. It was a philosophy all the Hokages held quite strongly."

There was contemplative silence for a while, and then Inari broke it with an angry speech. "You don't get it, do you? All that training you're doing, all those cool things you say, they don't mean anything! Gato will hunt you down and kill you all! That's what happens! The strong always survive and the weak always die!"

"Then it's the duty of the strong to protect the weak," Naruto stated calmly.

"Shut up! You don't get it, either! Always laughing and playing around, and even buying fancy new clothes! It makes me sick just to look at you! You don't understand suffering!"

Naruto laughed, a quiet, cold sound matched only by the frostiness of his eyes. "Really. I'm the one who doesn't understand suffering? And what of you? Crying and whimpering like a beaten dog just waiting to be put down. You're pathetic."

"Naruto!" Sakura yelled. "That's too far!"

"Shut up," Naruto spat coldly. "Zabuza was right about at least one of us. Playing at being ninja to impress some boy. Who's the loser now, hmm?" He stood up and walked out of the house, leaving everyone stunned, particularly Sakura.

Later that night, Kakashi went to talk with Inari. "Your grandfather told us what happened to your father, Inari. Believe it or not, Naruto does understand what you're going through a lot better than you think. He didn't have a father, either . . . or a mother for that matter. He didn't even have a single friend in our village, but I've never seen him cry, or sulk, or give up for even a moment."

He smiled gently at Inari through his mask. "I suppose he's one of those people that try to channel their negative feelings, no matter how strongly they feel them, into something that'll help improve their lot in life. True, it was harsh what he said to you, but he's probably said that to himself more than once. It's his way, odd as it might sound, of trying to help you."

Meanwhile, Naruto stood in a forest clearing by himself, looking at the pterosaur-styled white bracelet on his wrist. "So how do I turn this thing on?"

The Dino Minder, Mikoto spoke up. Pull the head open and then press the red button while saying, "Bakuryu Change."

"Fine, Nakadai-sensei," Naruto said. He pulled open the "head" of the Dino Minder and then lifted it to his mouth. He pressed the red button on the Dino Minder, muttering, "Bakuryu Change."

Immediately, greenish-yellow energy swirled around Naruto, taking away his clothes and replacing them with the skintight white-and-black suit of Abarekiller. Naruto looked at his hands, flexing his fingers inside the tight white gloves. "Wow . . . this feels awesome!"

This suit will enhance your strength and fighting abilities to an incredible degree, Mikoto explained. But you must learn to control its power first before you start using it regularly.

It isn't going to explode and take out the entire world this time, is it? Naruto asked.

Not this time, Mikoto replied.

Naruto reached for the short sword holstered on his left hip, pulling it out. It was a white blade with gold accents and black claw marks on the hilt, not to mention that the hilt itself was tipped by something that resembled the head of a pterosaur. "What's this?"

The Wing Pentact, Mikoto replied. My weapon. It's capable of a lot of things. I'll show you.

The next thing Naruto knew, he'd flipped the Wing Pentact so that the hilt was pointing outward and slashed the air with it. Oddly enough, a line of energy was following the movements of the Wing Pentact, and when he stopped, arrows made of energy were floating in the air. "What the . . . ?"

Fire them, Mikoto instructed.

"Sure," Naruto answered, pointing the Wing Pentact's blade out. Immediately, the energy arrows flew everywhere, impacting against both trees and ground and making a lot of explosions. "Whoa!"

Yes. Impressive, isn't it? Very useful for confronting groups.

"Like the Abarangers?"

Yes, like the Abarangers. And like the others you're going to have to fight. You won't always have single combats.

The next morning, Naruto awoke inside Tsunami's house. Training with Mikoto had taken a lot out of him, although maybe it might not have had he chosen to moderate himself. Hell, Mikoto had warned him, but Naruto had insisted on pushing himself past his limits.

"Morning, Naruto," Tsunami called out to him as he entered the kitchen.

"Where'd everyone else go?" Naruto asked.

"My father went to complete the bridge, and your friends went to guard him," Tsunami replied.

"They went without me?" Naruto asked.

"Kakashi thought you could use some rest," Tsunami answered.

Naruto growled quietly. "They left me behind." He smiled coolly at Tsunami. "I'm going to go to the bridge. See you around."

Unfortunately, as he leaped from tree to tree heading for the bridge, he spotted two thuggish men, one in a lavender-gray jacket and bandana and the other in a brownish-green shirt and scarred, heading toward Tazuna's house. Somehow, I doubt those men mean any good, Mikoto remarked in Naruto's consciousness.

Yeah, Naruto agreed. They could be Gato's thugs.

They probably are Gato's thugs, Mikoto countered.

With that possibility firmly entrenched in his thoughts, Naruto ran back to Tazuna's house, only to find the thugs herding Tsunami out. Taking a hostage to force Tazuna's hand, Mikoto thought. What a filthy coward.

Naruto shadowed Gato's thugs as they herded Tsunami across the wooden bridge. Just as he was about to swoop in, he saw Inari charging them, screaming, "Let go of my mother!"

I guess we were wrong about him, after all, Naruto thought. But he's going to die charging in like that!

He doesn't care, Mikoto answered. So long as he saves his mother, he's willing to die doing that. That doesn't mean we have to let him.

Naruto ran toward the scene, changing into Abarekiller as he did. In a rush of near-godly speed, he took down both thugs with the Wing Pentact's sword mode and swooped Tsunami and Inari out of harm's way. By the time he'd stopped, he was back to being "regular" Naruto, and Inari was looking at him with a stunned expression.

"How . . . how did you do that?" he asked.

"It was thanks to you, Inari," Naruto replied. "When I saw you were ready to die to save your mother, I figured I couldn't let you go out like that. So I went in, knocked those guys around a little so they couldn't go after you or your mom anymore, and got you two out of there."

"But how'd you do it that fast?" Inari asked.

"Ninja skills," Naruto answered. "The really good ninja can take out entire armies in the blink of an eye." He smiled warmly at Inari. "You're not pathetic at all. You're a pretty great kid."

To his own surprise, Inari began to cry. "I promised myself I wasn't going to cry anymore! And now you're going to think I'm pathetic again, but I can't stop!"

"It's no shame to cry when you're happy," Naruto said. "Anyway, take care of your mother. I'm gonna make sure your granddad stays safe. Believe it." And then he was off, with Inari shouting behind him, "Believe it!"

When he reached the bridge, he saw a dome of ice mirrors surrounding Sasuke, Kakashi and Zabuza facing off, and Sakura running toward that dome in an attempt to save Sasuke. She jumped into the air and threw a kunai at one of the mirrors, only for a ninja in a white mask to reach out of that mirror and catch the kunai.

"Let's see him catch this," Naruto muttered, raising the arm bearing his Dino Minder to his mouth. "Bakuryu Change."

In a flash of swirling green-yellow energy, the Zero suit replaced Naruto's clothes, transforming him into Abarekiller. In another flash, this time of speed, Naruto drew the Wing Pentact in sword mode and slashed the masked ninja, leaving a deep diagonal slice across his mask and knocking him completely out of the mirror.

"The number-one hyperactive knucklehead ninja . . ." the masked ninja commented.

"What a showoff," the wounded Sasuke groaned.

"Showoff?" Abarekiller echoed. "Is that how you talk about someone who just saved your life?"

"And who the hell is that punk and what does he think he is, dressing like that?" Zabuza asked disdainfully.

I have the feeling I know, but he seems different, somehow, Kakashi thought. And it's not just the outfit.

"Naruto!" Sakura exclaimed. "How did you pull that off?!"

"Skill, my lovely Sakura-chan," Abarekiller replied coolly. "Skill." He tapped the edge of his sword against his armored shoulder. "And now that I'm here, the tables have turned."

"You talk pretty big for a punk kid in a silly costume," Zabuza sneered, just before throwing four shuriken at the white-armored boy. Abarekiller's answer was to deflect each and every shuriken with his sword in a flurry of lightning-quick swings. "Heh. You've improved."

He has gotten rather impressive, Kakashi admitted. But he would have been far more effective had he stayed hidden.

"Wait," the masked ninja spoke. "I wish to deal with him myself."

Zabuza growled. "Still too soft . . ."

"And just who do you think you are, hiding behind that mask?" Abarekiller asked. "Pretending you're some kind of hunter ninja when you've been working alongside that bastard all along?"

"You are quite the master of irony," the masked ninja replied. "Do you not hide behind your mask as well?"

"Don't play games with me," Abarekiller snarled. "I'm going to rip your mask off, and I'm going to tear you apart."

He stalked toward the masked ninja, the pointed tip of the hilt aimed at him. He lacerated the air with the pointed tip of his sword, the light trail behind his lacerations forming into arrows that pointed at the masked ninja. With a swoop of his Wing Pentact, Abarekiller fired the light arrows at the masked ninja, who managed to either dodge or deflect them all with his senbon.

Sasuke drew a kunai from his pouch and threw it at the masked ninja, who dodged that as well. "I haven't forgotten about you. Rest assured, we'll finish our fight."

"Finish with him?" Abarekiller commented. "You'll have to get through me first."

The masked ninja's answer was to simply walk into the nearest mirror and seemingly melt into it, his image manifesting in the surface of every mirror comprising the dome. Immediately, a barrage of senbon assaulted Sasuke from all sides of the dome.

"Sasuke!" Sakura and Abarekiller shouted.

Kakashi was assessing his options. He could always go in to save Sasuke, and there was a strong chance of him succeeding in that, but that would leave Sakura alone to guard Tazuna. Sakura had fire, he knew that, but that fire wouldn't be enough to fight someone like Zabuza. Then he remembered Naruto, and his mysterious jump in skill and speed; if he could use that to save Sasuke and help him take down the masked ninja, then that would leave Kakashi free to take down Zabuza.

Yes, he would have to trust Naruto, it seemed. Then he looked at the dome again, and noticed that Naruto wasn't outside anymore; he was inside! "Well, crap. Even with these new skills, his brain hasn't caught up yet apparently."

Even Mikoto was internally chastising Naruto. I warned you this wasn't a wise course of action. But no, you wanted to save your comrade. Well, you could have saved him from outside.

No, I couldn't, Naruto answered. Might have had a better chance of fighting that guy outside, but not a better chance of saving Sasuke.

Sasuke glared at the white-armored boy. "You idiot."

"Is this how you treat the guy who's risking life and limb to save yours?" Abarekiller asked. "Really, some gratitude would be in order here."

"Gratitude?!" Sasuke exclaimed. "You could have done me a lot more good outside!" He turned away, fuming. "Well, I'll finish this." He began forming hand seals, launching, "Fire Release: Grand Fireball Technique!"

A wave of flame issued from Sasuke's mouth, consuming the mirrors. When it extinguished, the mirrors were still standing, but the edges had melted somewhat and there were small water drops marring their surfaces.

"So much for that," Abarekiller commented.

"Shut up," Sasuke spat. "You do better."

"I will." Abarekiller drew his Wing Pentact once again, ready to attack when the masked ninja struck with his barrage of senbon. Abarekiller attempted to deflect them, but they were so numerous that he couldn't get them all, let alone protect Sasuke from them all. Thanks to the armor of his suit, the senbon merely scratched him. Granted, they scratched Sasuke, too, but considering that he wasn't wearing armor, he had it worse than Naruto. "What the hell is this? Clones?"

No, Mikoto answered.

"Look as hard as you want," the masked ninja whispered. "You'll never discover the secret."

Abarekiller chuckled. "All I need to do is attack all of you at once." He lacerated the air again with the tip of his sword hilt, recreating the light arrows. Pointing the sword outward, he launched the light arrows in all directions, only for them to make a lot of noise and not a lot of impact. When the fog from their detonations faded, he could see that the most the arrows had been able to do was slightly crack the mirrors.

"So much for that," Sasuke taunted.

"These mirrors merely reflect my image," the masked ninja explained, "allowing me to transport myself from one to another at light speed. Through my eyes, you appear to be moving in slow motion."

Outside the dome of ice mirrors, Kakashi swore. "No wonder . . . it's a bloodline trait."

"Bloodline trait?" Sakura repeated. "What's that supposed to mean?"

"It means it's a power he was born with, passed down to him through his blood, his very heredity, and focused into a powerful technique that even I can't copy," Kakashi explained. "There's no defense against this, and no way to stop it."

Inside the dome, Abarekiller glared at the ice mirrors. "You really think I'm going to let you beat me? No dice. I have too much to do, too much to achieve, to let you kill me!"

"Is it a dream you speak of?" the masked ninja asked. "I have one, too. It is to fight for someone precious to me, someone I would walk through the fires of hell for, someone I would risk everything to help achieve his dreams. For that dream, I will fight you . . . just like you will fight me for your dream . . . and I have to, I will become a true shinobi, no matter how much it pains me, and I will kill you."

Abarekiller smiled behind his helmet, brandishing his Wing Pentact, as Sasuke stood ready to fight as well.

End Notes: There you have it, the first chapter of my hopefully epic "Naruto/Super Sentai" cross-fusion. More is definitely on the way, what with the finish of the Land of Waves arc and the beginning of the Chunin Exams. The latter will bring with it other reincarnations of Sentai warriors, and old enemies will join forces to menace the new generation of heroes. Think you can wait for that? If so, hang on for the ride, and see you next time!
