A/N

First of all, I would like to say that I do not own either Naruto, or any of DC Comics' products. As a matter of fact, I am only familiar with both of the universes through other people's fan works and the wiki-resources dedicated to the original stories.

Second, English is not my first language. Nor is it my second; it is my third language. Although I can speak it a bit better than my fourth and fifth languages, it still does not make me a native speaker. The way I use the language is not instinctual, it is conscious.

This entails some inconvenience for the readers. Well, for those of them who are native English speakers, anyway. There is a fairly good reason that people, as a rule, only translate texts into the languages they picked up as children. Even though this particular work is not a translation but the original, there is no big difference. While it may be possible for me to get the grammar right sometimes, the same cannot be said about the usage of words, syntax and stylistic devices. There could also appear some perceived implications, of which I, as the writer, would have no idea.

You have been warned.

Third, the story is M-rated due to swearing and future violence. I do not hate smut, but I am not overly fond of it either, so there will be no lemons here. I often end up skipping them, when reading other people's stories, so I would rather not write them myself. They are more often than not inessential to the plot, anyway. Besides, romance is most certainly not what is going to be driving this story.

That said, on with the story.

Prologue

The room in a glossy skyscraper at the western end of Jump City overlooked the downtown. On the inside, it was one of the most plain rooms imaginable: a set of simple furniture, a computer, a pale beige carpet, and a couple of big dark-red flowerpots with half-wilted plants.

What kind of unusual things could possibly be happening there?

Well, this was Jump City, so the question is not as rhetorical as it might sound to an ignorant audience, but, at the moment, no rampaging supervillain or superhero vigilante graced the building with their majestic presence, although, things like that happened in the city from time to time. As a matter of fact, there was no one in the apartment. Not a soul, except for a teenage girl who sat on the windowsill.

She was unusual.

The whisker-like marks on her cheeks and the rhombic dot on her forehead were the first thing one would notice upon looking at her otherwise unblemished pale face.

The second thing worth notice was her military-looking gear, which felt out of place for two reasons. First, the girl was a teenager and thus not entitled to possess any kind of military gear at all. Second, said gear consisted of bandages, wrapped around her calves; a supposedly medical kit, smelling of herbs rather than ethanol, phenol, or any other antiseptics; a sturdy green flak jacket she wore over a black cloak; and a strange outlandish knife the girl was twirling in her hands. The knife had a diamond-shaped business end, a thin braided handle, and a ring wide enough to put a finger through. The girl also had a porcelain bear mask lying beside her. The rolled-up sleeves of the cloak revealed her hands, covered with tattoos — or rather seals, which, admittedly, were indeed tattoos. They were simply not meant for aesthetic purposes.

Her blood-red rippled eyes with nine tomoe would be the third thing to draw attention, although only the girl herself knew what exactly they were and what they could do. To answer the implied question, they were the Rinne Sharingan, doujutsu that allowed the user to transcend humanity and to rewrite reality at will, as well as to use nifty little tricks.

The window frame was empty, the glass long gone. The girl, however, did not mind the breeze. Considering the fact she was the one who had shattered the glass before sending the shards away with a very special doujutsu technique, known as Kamui, her willingness to endure the air was not exactly unexpected.

Her name was Uzumaki Naruko, and she was not of this world, having been displaced along some extra dimensions and, most likely, along the basic three as well (otherwise, she would have ended up in outer space, not unlike the myriads of less fortunate dimension-travelers).

At the moment, Naruko was staring eagerly into the smoggy distance, the Rinne Sharingan spinning in her eyes, and smiling as the soft wind played with her blond pigtails.

The smile then grew into a sneer; apparently, Naruko had just seen something of interest to her.

'You're one vicious little vixen, you know that?' the voice of a certain former demon fox grumbled in her mind.

'Look who's talking, a demon fox,' she answered leisurely, seemingly unfazed.

'Well, I'm not exactly little, am I? Besides, the point still stands.'

'Shut up, Kurama.'

'No, seriously, I mean it.'

'I said, shut up,' Naruko answered, a tad more irritated.

'You need to get laid,' concluded the demon fox.

Naruko gritted her teeth, balling her hands into fists. Apparently, she was not happy to hear that.

'And how, pray tell, do you expect me to do that?'

'I don't see a problem as long as you are finished sorting through your previous incarnations' memories.' The fox would have shrugged if it had been capable of such an action.

'All of whom had been straight males,' Naruko said acidly. 'And for your information, I'm already done, but I'm not sure, if I really am Naruko.'

'Switch to girls then,' the fox suggested helpfully.

'Not happening. Now shut up.'

'All right, seduce some boys and get over it,' it made a new suggestion.

'Not happening either. Now shut up,' she growled.

'I still think you really need to get la—' began the fox, but it was cut short by the girl.

"I said shut the fuck up!" the knife—the kunai— sank into the sill with a loud thud. "I do not want to, got it? You should know, you're the one who's killed my libido!" she yelled. She would have scared someone with that yell, had she not been alone; not physically, at least. "You've even gone as far as to shut down my menstrual cycle!"

This is where the fox would have pouted, but, alas, it could not.

'That was never my fault, much less my intention. You're being irrational. In case you failed to notice, I used to be a giant sentient genderless mass of chakra, never meant to procreate. Sexual drive is not something I was supposed to possess. Merging with me would bring irreversible consequences, I told you as much.'

'Yes. Yes, you did,' a now calmer Naruko nodded absent-mindedly, as she plucked the kunai out of the sill and went on with twirling it. 'Now, be a good little fox and stop pestering me.'

'I believe we've just found out I am not little... Aw, come on, kit, it always worked for Kushina and Mito! You should try it!'

'How many times should I tell you I don't care? Besides, I don't want to hear about my mother's sexual activity.'

'Your loss, then. She was qui—' the fox trailed off, having felt Naruko's murderous anger.

Despite herself, the corners of the girl's mouth quirked up.

'I don't think so. I know that your seal used to be much less comfortable back then, so you kind of couldn't be in the mood for peeping. Besides, even if you weren't lying, my circumstances are still different. Now could you be so kind as to shut up? I've been getting annoyed by these talks lately.'

The fox, however, just would not let it go.

'Now, about the circumstances... While I may have killed your libido, you're sixteen,' the fox said. 'You've been an adult for four years. You could have gotten married to someone already, you could have had kits of your own, but you never had. I refuse to take the blame for that! In fact, I blame the stupid cripple for your prudishness. You know how he was, training, training, more training, a mission, more training, more training... Crazy, that one.'

Naruko froze, no more twirling the kunai.

'You better watch your filthy mouth. You will not speak ill of Danzou-sama,' her inner voice was quite icy.

'Dear Inari-sama, what did I say?' the fox gasped in feigned horror.

'I will not tolerate anyone speaking ill of Danzou-sama, not even you. You have just spoken ill of him,' elaborated Naruko, refusing to pick up on the mocking tone.

'You do realize I never said it was him?'

Naruko did not answer.

'Hey, kit! Is it just me, or is he your only true love?'

Naruko's brows twitched before she sighed, deliberately calming down. This was not the first time the fox was getting on her nerves. She could deal with that.

'Shut up or I'll shut you off myself. It is thanks to Danzou-sama that I was given the Mokuton and the Sharingan, it is thanks to him that I defeated Kaguya. If I had been too weak, we would have been no more. In the end, not only did he protect Konohagakure no Sato, he saved the whole world!'

'By proxy. You,' the fox objected.

'It matters not. While I cannot make you show Danzou-sama proper respect, I am quite capable of not hearing your disrespectful, arrogant, ill-timed and ill-directed—' she never finished, as the fox interjected hastily.

'All right, all right! My, no need to get so excited. That was a joke. A bad one, I admit. I'm sorry, all right?'

'All right then. See that you don't do that again. Well,' she sighed once more, 'for at least a couple of days.'

'You got it!'

Silence settled in for a couple of minutes.

"Say, Kurama... Now would you look at that? Hook, line, and sinker," Naruko smirked, breaking the silence, as she stared intently into the distance yet again.

Of course, seeing that it was not English she was speaking, her original phrase sounded different as well as had a different literal meaning, otherwise Kurama would have immediately cracked a joke about fishermen.

As it was, however, it merely gulped in a exaggeratedly dramatic manner.

'Yeah... Not creepy at all.'

'Oh please, that's just an innocent prank,' Naruko huffed, folding her arms.

'Innocent, my ass. For a former Root operative, maybe. Although I wouldn't expect any of the others to bother if they were in your place. But can't you see you're going to break those people? That's some prank. Like I said, vicious.'

'But they really do have issues the size of this city,' Naruko pursed her lips. 'And I happen to hate their no-killing rule. They take it all as a sick game, and I don't mean just the youngsters. Almost every single dangerous offender gets to get away on a regular basis. Imagine my surprise when I found out that the first guy I offed in this world had been in action for years! What about future casualties? Are those people capable of consideration at all? They all need a lesson. Badly.'

'Well, I don't have to imagine. I kind of never left your head ... stomach ... whatever! But I suppose you're right on that one. Still, I fail to see how what you've set up would be an appropriate lesson. Why don't you drop it, while you still can? You're going to waste resources.'

'Come on, nobody's going to get hurt, other than my clones, that is. Well, they are going to take the little heroes' respective egos with them, but that's about it. Good riddance, I'll say!'

'Clones!' cried the fox in disbelief. 'Those are actual bodies! You've had them growing in those chakra-pods! You've gone so far as to imitate their supposed age and non-human origin on the molecular level. Not even blood clones are that... that...' it obviously was at a loss for words.

The girl shifted, her legs now dangling out of the window. She was absolutely unperturbed by the hundred and something floors between the ground and her feet.

'Still my clones. Still get their memories, experiences, and chakra back after their death. Your point?'

'Oh, I don't know... How about, you've gone out of your way for a prank of all things, eh? Those bodies are something good old Orochi-kun would've given all his limbs for. And his tongue. Can't forget about the tongue.'

'But it wasn't impossible,' the girl smiled. 'Tsunade-baa-sama was a good med-nin and a teacher.'

'Like I'm going to believe that. The drunk can't sober up to save her life.'

'Well, that's just not true,' Naruko pouted. 'And she really was and, I hope, is magnificent. She has undone the damage done to me and taught me everything she knew. That's an accomplishment in its own right. Especially the latter.'

For a moment or two, Kurama was silent.

'Hah! You finally admit you'd been broken at Root? Got you!' the fox finally exclaimed with mirth.

'No,' Naruko said flatly, disgusted.

'Here we go again...' it sighed. 'What did she undo then?'

'Damage.'

'Told so.'

'At Root, I've never suffered any damage. Danzou-sama always was needlessly respectful.'

'Oh, really? Where have you suffered it, in that case? Do humor me.'

'I...' Naruko said reluctantly before pausing for a heartbeat. 'Somewhere. Not at Root, though.'

'Keep telling yourself that. On the second thought, don't. Either way, you've gained godlike powers, both through training, apprenticeship, and by your defeating Kaguya, and now you're using them for the sake of the most pettiest prank I can think of! That is my point.'

'So?'

'So! You're using the legendary Rinne Sharingan to observe your so called prank and its aftermath. I cannot even begin to comprehend just how trivial and insulting to my father that is!'

'That's not a very good point. That Suupaaman fellow also seems to possess godlike powers. His, perhaps, are even more impressive than mine. Can't tell which are superior, though, have to fight him first to figure out that one. Anyways, he only utilizes his powers to fight crime, from what I gathered. While that might be admirable, he never goes full out, nor does he do something productive. He could carry a lot of things into orbit, for one, but does he ever? I seriously doubt that. Whereas I am, at the very least, using the Mokuton to grow beautiful trees and juicy fruits. And should I remind you, who's supplying Konoha with all the useful toys that are not produced in our world? Gamakichi has been busy, you know.'

'I'm not going to argue that, but you can't know for sure what that superhero does and what he does not. You can't speak the language that good.'

Naruko shrugged.

'Maybe not, but I count on Mi-chan's help to make trivial judgments, since she's a local... compared to me, that is. And she does not exactly like him very much. Besides, now that I've figured out enough to understand what's written in the newspapers as well as to get by, I'm going to make big progress. All I have to do is to use the Rinne Sharingan to memorize some dictionaries.'

'People don't speak dictionaries, kit, they speak languages,' said the fox sagely. 'Forget that, they, first of all, speak. No doujutsu can help you with that, unless you dump somebody else's memories into that pretty head of yours, but it isn't too useful for language-learning either, as we've already found out the hard way.'

'"We?" Really, Kurama? You didn't have to endure that.'

'Well,' the fox said sheepishly, 'I'm still kind of right, am I not?'

'Yeah... That's exactly why I'm going to practice a lot.'

'By abusing your shadow clones,' the amused fox supplied.

'But of course. Why would I deprive myself of such an easy way to accomplish my goals?' the girl smirked.

'I thought you'd like the challenge.'

'No, not in this case.'

'I so didn't see that coming.'

'I bet, you—' she never finished the thought and snapped her eyes back onto whatever she had been gazing at previously. "Whoa!" she exclaimed. "They've finally begun! Can't wait to see their faces when they pull this one through. Come on, come on, just do this, just make it. Show it to me," she bounced, excited, even as she spoke.

'Now that was really creepy,' the fox sighed once more, but Naruko paid no attention to its words, absorbed into the scene that was unfolding before her enhanced eyes, miles away.

Nobody noticed her, and even if someone had, they would never have connected the dots. With her apparent glee and not so apparent reason for it, she could very well pass for yet another supervillainess, for all people knew. Now, supervillains were known to be an ambitious bunch; a non-lethal prank unfolding miles away just would not account for a villain's good mood. Especially not a prank that was not meant to be discovered as such.

Naruko knew that, too, and she was going to enjoy what she saw to the fullest.

A/N

This was the prologue.

I do not have any idea how soon the first chapter will be up, if ever. I am not well-versed in the DC universe. I always knew of Batman and Superman, but this is it. The problem is that do not really know what to look up first. No, seriously, the DC timeline does not seem to make any sense. All I got is a headache. So, no promises.

As of now, the city, where Naruko pulls the prank on the Justice League and their associates, is Jump City, but that particular detail can be changed easily. What the prologue has is what the last chapter will have, except it is given from another perspective. There is a long way to go, so I am open to suggestions.

I plan on Naruko landing in Gotham before moving to whatever destination that attracts her interest. That will take some time.

And, yes, she has a bear ANBU mask. I speculated that Danzou would not risk discovering his agent's identity through her wearing a mask somehow related to her.
