This story is brought to you by a nagging idea in my head that would not leave me alone. I've just recently re-watched the whole Young Justice series along with the Boruto movie and BAM it hit me like a train. I love crossover stories and I just had to try this. Let's see how this goes. I don't own Naruto or YJ. I write because it's fun.

It was common knowledge amongst the residents of Gotham that once the sun sets beyond the horizon, you better get off the streets as soon as possible. The chances of getting mugged, robbed, shot, stabbed, killed, or raped increase exponentially once the criminals come out to play. If you were lucky, you'd be able to get home unscathed as long as you don't linger in one place for too long or wander someplace you're not supposed to.

Of course, the city did have another reason to be known throughout the world aside from the large hive of criminals and psychopaths. Just like Metropolis, who had the Man of Steel to watch over them, Gotham was under the protection of the famous Dark Knight himself. It was thanks to him that small time thugs and gangsters would always think twice before going out at night.

As for the man in question, he was currently perched on a tall building as he observed a small street along the downtown area through small binoculars.

"Any sign of activity?" Batman spoke into the built in communicator in his cowl.

"Looks like a quiet night as usual, Master Bruce." Alfred responded.

"Keep me posted."

Batman resumed scanning the neighborhood for anything out of the ordinary. He was investigating this particular street because something wasn't right. It was the fact that he was in the downtown area, the place where the large amount of the small time criminals roamed, and yet there was nothing happening. That in itself was the kicker.

In Gotham, there was always something.

Batman frowned and put away his binoculars. He fired a grappling hook and zipped over to the next building to get a closer look. Gazing down at the nearly empty streets, he frowned as he failed to spot something noteworthy to provide him with answers.

He had stumbled upon this neighborhood after he stopped a gang war from breaking out. Apparently, they were fighting over territory. One group had apparently been chased out of their previous turf and was looking for a new place to set up shop. He had interrogated one of the thugs but he had been tight-lipped about why they had been kicked out. Even after tossing the thug around a few times wasn't enough and he ended up being knocked out.

Batman could only assume that they had been driven out by someone or another group. Obviously, he couldn't allow this new group to get too comfortable in his city and so he had set about to investigate. Unfortunately, progress was minimal even after two weeks of recon. In fact, he had more questions than answers.

The first sign that alerted him was the fact that this area had no sign of criminal activity at all. For as long as he had lived in Gotham, he had never seen such a quiet and peaceful neighborhood. No one committed any crimes along this street in particular. Batman had questioned more unsavory individuals around the area but to no avail. It appeared as though they were afraid of something and that all he could get out of them was that there was an unspoken rule about not causing any trouble within that area.

Batman's second clue was slowly walking down the street. The Dark Knight frowned as he made note of the person carrying a shopping bag in each hand. He looked like he had just gotten back from the super market. His blond hair was short and spiky and he wore a plain orange t-shirt along with jeans and sneakers.

He observed the young man as he entered an apartment building. A few minutes later, Bruce used his binoculars and switched it to infrared. The man had entered his apartment and set down his purchases on the table. Batman watched as the man set about his normal routine. He made and ate his dinner, watched television for an hour, and went to sleep.

Batman frowned as he put his binoculars away. He showed no sign of suspicious activity. Of course, there was no solid proof of it but Bruce was convinced that this man was the new player that everyone was talking about.

Naruto Uzumaki had appeared out of thin air less than a year ago. His papers had been forged expertly and if it hadn't been for Batman's vast resources and expertise, he would've thought they were legitimate. Other than basic information, nothing else was known about him and Batman hated the unknown. Naruto could be a threat that needed to be stopped at all costs and Bruce would work under that assumption until he was certain that the blond wasn't.

He also found it suspicious that Naruto moved into this neighborhood at the exact same time period when all crime within the vicinity stopped completely. Not even a petty pick-pocket could be found around these parts anymore.

Coincidence?

No

His musings were interrupted as Alfred contacted him.

"Master Bruce, I hate to interrupt but there seems to be a flurry of activity in the central district." Alfred informed him. "It appears that the Joker has released large amounts of his laughing gas near Gotham General Hospital."

"I'm on my way." Batman responded before pressing a button on his utility belt. The Bat mobile should be arriving at the designated location at any minute. He gave one last look over his shoulder to where his suspect was sleeping and fired his grappling hook.

His investigation would have to be put on hold.

He jumped into a nearby alley and landed next to the awaiting vehicle. He climbed in and accelerated to the location Alfred sent him. He couldn't afford to delay whenever the Joker was involved.

Unknown to the Dark Knight, a pair of sky blue eyes had been watching him from the very beginning and followed the bat themed vehicle until it disappeared from view. The figure stood from his crouched position a few buildings away and popped out of existence in a cloud of smoke.

The wave of memories assaulted him as his clone disappeared. He was beginning to wonder if the Bat would spend the whole evening just watching him pretend to sleep. Apparently, the big guy had other things to worry about than little old him. Honestly, this was starting to get old and just a tad bit annoying. He could ignore the first few attempts in the past but two whole weeks in a row was pushing it in his opinion. He wasn't bothering anybody and all he wanted was to be left alone.

After all, he had nothing else to live for anyway.

So that's the prologue. Short, I know but I'm just kind of setting the tone. Bit of a depressing beginning but it'll make sense in the next chapter I promise. Now I just want to clarify that the Justice League hasn't been formed yet and I'll be borrowing some events from the series cuz I need to set things up before we get to the Young Justice timeline. Also let me make it clear that Batman still hasn't met Robin yet.

BTW this is my first story so please go easy on me, yeah?

For now tell me what you think and review.
