Summary: In which James Potter, Sirius Black, and Remus Lupin change the fate of two worlds. Such is the result of the butterfly effect. HP/Naruto Crossover

Butterfly Effect

"When a butterfly flaps it's wings, a hurricane arises on the other side of the world."

Determined hazel eyes looked upon their hard work even as beads of sweat formed on a tired forehead and disheveled midnight hair was annoyingly brushed away. Tired hands smeared with ink and paint then rubbed the eyes closed. He was tired but oh so very close. Another feat would be added to his and his friends already impressive list of accomplishments. Tonight, history would honor their names and hail them geniuses because they couldn't be called anything less. Tonight, this very hour, their names would go down in infamy and legends would be told about them for ages to come.

"And Lily will finally have to say YES to going out with me!" Hazel eyes lit up and pumped a fist in the air as he thought of the best prize of all.

A snort came from his right, "Figures that be the only reason you'd goad us into something so stupid."

"Aww... Lay off him Moony! You know Prongs is only being an idiot in the name of loooovvveee!!!" a voice cackled from the left.

Hazel eyes burned as he studied his two accomplices. He first turned to glare at the first one who had spoken. Light brown, almost golden hair adorned the bowed head even as ink smeared hands, much like his own, finished up their own part in the array they were so carefully conjuring. The head seemed to sense his gaze and looked up. He was met with a pair of golden eyes and if he stared long enough, he'd be able to see a silver, almost animalistic glow, come forth. The face itself was unusually stunning and hazel eyes observed the grace and poise the figure moved himself with. Suddenly that face split into a handsome grin and so he turned to look at his second companion.

He was met with dark silver eyes, one of which was arched up, as if in challenge. This face too was devilishly handsome. So much so that hazel eyes often found themselves rolling as girls everywhere swooned for his friend. His striking face was adorned with hair as dark as his own coming down like a dark curtain. His hands however weren't smeared and inked. They were holding a thick book along with a pen. Suddenly he saw the lips move and he met the silver gaze head on.

"Prongs. I know I'm gorgeous beyond belief but stop staring. Now. It's creepy." the voice dead panned.

'Prongs' rolled his eyes and gave his famous I'm-so-hot-and-I-know-so-I'm-going-to-use-my-hotness-to-evade-and-or-escape-some-situation-I-don't-even-know-how-the-hell-I-got-in smirk. "Padfoot, Padfoot, Padfoot! I know you want me and I hate to break your little Black heart like this but I'm taken—"

"By who? Last time I checked Lily would rather have a trolls baby than stand your presence in the room for even a minute." a voice chirped from his other side. 'Padfoot' began to cackle loudly.

"Nice one Moony! Ha ha! Get off your high horse Prongs! Or should I say 'High Stag?'!" Padfoot cackled some more. Prongs felt the pout on his face and knew his friends had seen it as evidenced by their laughter heightening in volume and dramatics.

"One of these days you-know-who is going to blow me up and then you guys will regret being so—so, so mean to me!" Prongs gave a mock sob as his own dramatic exclamation increased the laughter.

"Shh!" Moony finally snapped after a while even as he wiped tears of laughter from his eyes. "Someone will hear and then all our months of planning will be wasted."

Padfoot quieted down and turned serious eyes (for once) to his two friends." What WILL we do if this shit we did actually works?" They both turned to Prongs who had gone quiet as well.

"Well...we could let the Ministry in on it and help others with what our genius came up with or..." he gave his most devilish and sexy smirk he possibly could. "We could keep this within our little circle and be known as the Master Pranksters of ALL worlds."

"Be serious Prongs."

"How about we get rich quick with it?"

"Why do you always ask me my opinion and then burn and crash me?"

"Your face full of disappointment is hilarious as shit."

"I keep hoping your brain will evolve and mature and give a good answer."

"HA! You'll be waiting a while then Moony."

"I'm more mature than you, you mutt!"

"As proven by your protruding tongue Prongs."

"Oi! Put it away unless you want to use it."

"Ha! You DO want me!"

"Hell yea I do! To shut up!"

"Stop acting like idiots! Prongs! DON'T. YOU. DARE!"

"OW! Merlin's extremely long beard! That fucking hurt Moony!"

"Wow. For the school's best seeker, you're slower than a turtle stampeding through peanut butter. How embarrassing—OW!"

"HA! Good aim Moony! Hit him right in the—"

"Shut it! Both of you!" Moony finally snapped and eyed both friends warily. Prongs and Padfoot couldn't help it. They whimpered under the golden gaze of their companion. They scooted closer and held each other, trying to offer the other as much comfort as possible. Moony rolled his eyes and looked down on the array they had drawn.

"Basic alchemy. Except some of the symbols we replaced with magical insignias representing the elements of change such as water and fire..." Moony murmured and both previous cowering friends joined him in analyzing their work.

"Hey, where's Peter? If something goes wrong maybe we can blame it on him—" Padfoot was stopped with a light smack to the back of his head.

"Shush. You know the only reason we didn't let Peter in on this is because he can't keep a secret. I feel guilty. He's our friend." Moony sighed while Padfoot scowled.

"Friend? Pft! More like fanatical stalker. The bloke practically worships the dirt Prongs walks on—"

"—As should everyone because I'm so awesome—" Prongs quickly interjected haughtily.

"—if it was someone worthy of praise, like me, then maybe I'd understand. But Prongs!? Heed my words: one day that rat is going to snap and kill Prongs. And then he'll stuff 'im! Taxidermy I tell you! Prongs will forever spend his afterlife hanging on some wall being worshiped with incense and dried grass!"

They stared at the raving brunette for a minute before turning back to the array.

"Should we do this some other night? We waited this long, one more night won't hurt." Moony murmured. Besides him, Prongs shook his midnight hair and raised his glasses higher on his nose.

"Tonight. The sooner the better. Watcha say Padfoot!? Come on Moony! Tonight, the Marauders rise to infamy once more!" Hazel eyes shone with determination as he stood in his determined spot for the ritual. Moony sighed but moved to his spot and gave a crooked grin. Padfoot stopped his ranting to cackle loudly before bounding to his own place.

"Okay, on three we channel our magic and feed it to the array. Padfoot, got the runes translation?" Prongs straightened his robes and turned to his dark haired companion. Padfoot grinned and threw both his friends copies. They caught them and everyone read through quickly before looking at their companions.

"On three." Prongs started. "Ready, set, go!"

"Three!" Moony grinned.

"Two!" Padfoot laughed.

"ONE!" Prongs yelled.

They started to read in unison even as their magic flared and they willed it to go to the array. "Water!" they said evenly even as the insignia for water flared to life with a blue glow. "Fire!" the same thing happened to the fire symbol but it lighted up with red. "Air!" lighted up with white light. "Earth!" Lighted up with green light.

Everything seemed to be going perfect and Prongs internally cackled with glee. With this, Lily would HAVE to love him! She'd be begging for his hand in marriage! Oh, life was so sweet! And it continued being sweet until Moony opened his mouth.

"JAMES! You idiot! You wrote fire twice!" the normally calm friend roared. Prongs looked at the array.

"Eh?" he looked and sure enough the symbol for Earth was not Earth but Fire, lighted up in green. Oh...no. If they lived through this Moony would no doubt use him as a chew toy...

"SIRIUS!!! YOU BIGGER IDIOT! This isn't the translation for water! It's mist! UGH! I'M SURROUNDED BY MORONS!"

Even as their golden eyed companion turned to kill them the array seemed to be wanting to go first. It flared with fire then a green light somewhat exploded within the middle and it seemed to expand almost as if...

"IT'S GONNA BLOW!" Padfoot screeched. So they took off at a run from the room they had been occupying on and off for the last month. Just as they were half way across the room and so close to the door, the array did explode and gained on them quickly. Too quickly.

"I'M TOO SEXY TO DIE!" Padfoot screeched and Prongs saw him engulfed by the emerald flames and knew deep down that it was probably true.

"I HATE YOU BOOTTHHH!!!" Moony screeched as he too was eaten by the flames. Knowing that no one was around and he was most likely (100% sure) going to die next he screamed out something he most likely owed his fallen brethren.

"I WAS TOO COOL FOR YOU GUYS ANYWAY!" and Prongs felt the emerald flames engulf him and it felt something similar to being dunked under water, strange seeing as they were supposed to be burning, not drowning. The last image he chose to see was of his lovely and dear red head, the woman he had chosen out of all others to bear his name and children. His lovely green-eyed Lily.

"Wake up you dolt."

The prod to his side gave him no other choice as he was viciously assaulted with a bright and fierce glare as soon as he opened his eyes. He sat up and coughed. He looked to his left to find both his friends sitting there and watching him. Varying degrees of madness and homicide in their eyes.

"Good. You're awake. Now I can kill you."

Hazel eyes blinked. "Am I in hell?" he asked.

"Do I look like the devil?"

"...answer my question first. Then I'll decide what to say."

"Prongs." the answer was growled out.

"...where are we then?"

"Who are you and what village are you affiliated with!?"

Prongs wasn't so dazed and smacked stupid that he couldn't process the fact that someone else was talking. Unless his friends had somehow changed the tenor of their voice and managed to learn how to convey they would soon die without giving a proper and decent answer all in those few words spoken...even if it was in some foreign language he couldn't even get two words out of.

Prongs ran a hand through his hair even as his eyes landed on a blond man with sparkling blue and steely eyes. He was clad in a green vest with black pants and a black shirt. The most unusual thing about him was the fact he was wearing this strange head band thing on his forehead that had a small symbol on it which kinda reminded him of a leaf. Kinda. Maybe a pointy arrow.

"Er...eh?" he asked intelligently. He heard Padfoot groan and Moony sigh.

Again the man spoke and signaled the area around them with a hand. His gaze was serious and spoke volumes of the fact he could easily hurt them.

"Er..." Prongs felt the beginnings of panic starting to engulf him. "No hablo foreigner!" he tried.

"Ugh! You stupid! Its obviously not any language we know! Good thing I know the spell for language communication."

And then Moony, the smartest one of the three currently lying in the mud, seemed to do the most wrong thing he could short of throwing a rock at the man who looked like he could squish them with his pinky. He dug into his robe and pulled out his wand. The stranger froze and with inhumane speed he was suddenly right in front of them. A sharp knife type thing in both hands, pointing at Moony's neck and Prong's own neck.

Padfoot decided to speak up then: "KILL THEM IF YOU MUST! JUST DON'T HURT ME! I CAN BE FURRY AND LOVEABLE!"

The man turned to Padfoot who was on the verge of hysterics and Moony had enough time to whisper the spell so both Prongs and him could understand.

"We come in peace!" Prongs tried in the new language. The man turned to him and raised an eyebrow.

"I'm sorry sir! We meant no harm! We're lost and we're very far away from home. Please, it's the truth." Moony said with as much sincerity as he could. Prongs could only nod dumbly and Padfoot was currently useless as he wept at the fact that the world would become more ugly without his presence.

"Civilians." the man mused. He put the sharp knives away but leveled them with a stare. "The Sandaime needs to know about this. Come along. Don't do anything stupid or I will kill you." he warned them and hauled Prongs up first. Moony got up and quickly slapped Padfoot before pulling him up as well.

"Er..." Prongs felt the man's stare on him. "I'm James Potter. Don't kill me." he whimpered the last part and hoped his poignant face would work on this man same as it did on his mother.

Moony spoke up next. "I'm Remus Lupin." he shoved at Padfoot to say his name but when gurgles and hysterical sobs was all he got he introduced their other friend. "This is Sirius Black."

The man looked them over and James had the distinct impression he deemed them as threatening as kittens. He gave a long look to Sirius and his lips slightly twitched. He turned to them fully and met each of their eyes.

"Namikaze Minato."

IMPORTANT

I had an idea and I kinda wrote this on a whim. Don't know if I'll continue this or not. Depends on the response and if its good and enough I'll solidify the plot and go back and fix mistakes and such. Most likely will contain YAOI (boyxboy)
