Naruto x Arturia x Mordred x Morgan x Gilgamesh


"You're thinking too much, Master. Just tell me who needs killing. I'll do the rest."

"It isn't that simple! You can't just wade in and-ow! Don't pinch my cheek!" "

What did i just say? Thiiiiinking tooo muuuch!"

~A Conversation!

~XxX-xxXXxx-Year 2,000 BCE-xxXXxx-XxX~

The battle had been raging for hours. The Roman Deities had once thought themselves so superior to him. Hundreds of God's turned into thousands once he began laying waste to their numbers, and now he found himself surrounded by the entire Pantheon. Had he taken notice, he would have realized that Seven whole days and Seven entire nights had already been waged against this overzealous Pantheon of brother-sister fuckers and he himself was running precariously low on power.

He taunts the Roman deities around him, "Come on!" he calls out to them. But when he hurls his hammer to take out a golden haired man, the remaining Roman deities seize the opportunity. A group of them swarm the blond Norse from all sides, keeping him separate from his weapon. The chunk of mystical metal falls to the ground. An armor clad man with a maniacal gleam in his eye desperately struggles to lift the simple thing off the ground, to no avail.

The unknown Norse, still without his hammer, fights his foes mercilessly, a man consumed by blood lust. From a distance, a brunette woman with a spartan helmet and fearsome shield held a spear in hand and takes notice when she sees the look on his face - the savage thrill of the heat of battle. With a thought, the man now has his hammer in hand, and he slams it into a screaming warrior, "This all you have Roman's!" he cries as he turns and hurls it, pounds of flesh could be heard, dozens falling as the hammer plows through them as the others witnessing begin to retreat from the fight.

The goddess of War and Wisdom watches silently as she looks at the berserk blond, "There are too many of them!" she sge says, "He cannot hold out for long, he will fall soon enough." she notes as she begins to turn away from the pointless bloodshed.

But, despite being overwhelmed, the Norse continues to battle on, consumed by the raw fury of his hatred, the gratification of being able to slaughter his enemies, the relish of battle. The potential for dying was almost guaranteed, but he would go to Valhalla, his family, when he perished once more.

He battles valiantly, but there's just too many of them. The Roman deities swarm him from all sides now, as he disappears beneath a pile of flesh. After a moment, the overwhelmed Norse God manages to raise a fist as he forces its up through the middle of the pile of Roman's. He opens his hand, beckoning. One of his attackers hears something roaring up behind him. He whirls around - BAM! - the hammer nails him square in the face, then flies into the mans outstretched hand.

Pulling himself up out of the pile of gods, he soars high into the air, and dives back towards the ground. As he does so, he raises the hammer up high, and with a snarl, brings it down on the ground with all his might. KRAKABOOM! Thunderclouds expel a thunderbolt unlike any other. The lightning strikes down from the sky, the hammer channeling the blast, firing the electricity out at the stunned deities around him. They're blasted back in a massive shockwave. The land around shudders as the Roman God's begin to convulse before they inevitably drop dead.

However, thanks to the force of the blast, the land also cracks the plate of the continent below, the shockwave continuing to spread outwards. The ground physically begins to ripple, almost similar to when a pebble is dropped in a pool of water, and then it begins... the devastation. It moves out to where his enemies are running, fleeing from the terror of this madman, breaking up the ground beneath them, exposing the black void of the abyss below. Even as they flee, the ground is torn apart; the entirety of the plate they stand on falling apart. The masses cry out in terror as the void of darkness claims them when the ground falls out from under their feet.

The Warrior Goddess stumbles and cries out in shock, "What has he done!?" as she watches the aftermath.

The destruction spreads, the land ripping itself apart. The land collapses, water from the sea rushing inland to fill the gap that had once been a landmass. With this single act of utter defiance, the invading Norse had ripped a chunk of a continent apart, wiped out entire countries-not to include her Uncles beloved city of Atlantis among others-and killed untold numbers of people. She had managed to flee from the devastation on her chariot, along with a selcet few other's, but she could only watch as the waters of the Mediterranean Sea rushed inland. For 500 Miles the water's purged anything and everything without remorse.

500 miles... that was the distance the water's rushed inland. And an additional 120 miles was the sheer width of the devastation he had wraught upon the world. The might of the Norse was not to be underestimated, for with but one swing of the World Ending weapon, he had wiped out over 98% of her pantheon. A total of 20 or so of her fellow god's remained to tell the tale, but she could feel it even without having to ask. The devastation had wiped out hundreds of her temples, ripping her divine authority away from her, not to say anything of the other's who had similar temples across the landscape that had been wiped off the map.

In time, this mass of water would come to be known as the Adriatic Sea, many would forget its origins and how it came to be, but the world would not. The mark of berserk deity had etched itself into the mind of Gaia, with respect on both the level of strength he exhibited, and the sheer audacity the man held to attack her family in the midst of their own lands with no qualms. Yes, this man was worth the respect and honor of entering the Throne of heroes indeed. Five Classes assigned: Caster, Rider, Archer, Lancer, Berserker were his suited sets. He could use a sword and be a Saber if forced, but it was his worst class. So yes, a berserker was his most suited classification.

~XxX-Current Era-XxX~

Illiya didn't understand her Servant. How could she? He didn't make a lick of sense! No way of knowing his class, not telling his motives. He could be anything. A small part of her knew it was her own fault. She'd jumped the gun. Her impatience had gotten the better of her. She'd wanted to be the first to summon a Servant in the coming war. Arrogance on her part to be sure, but after all she'd been through she had little pride left. Pride and anger were all that kept her going these days. And right now? She was feeling an awful lot of anger, "You're a little young for a mage, aint'cha?" Illya bridled.

"I'm older than I look!"

"Fair." he grunted. "I'm not one to judge. Seen one mage, ya seen 'em all...

"..."

It should have been Heracles! But this wasn't him! How did you summon the wrong servant with a catalyst?! The warrior sprawled on the sofa before her was a blond man; bright blue eyes framed by rough blond hair and whiskered cheeks. Standing presumably at 7'5" high (approximately 226 cm), taller than Heracles who was a even 7'0" even in his Berserker State. His belly is kept virtually naked, unarmored to make it appear more pronounced and sports a variety of runic tattoos on his body, although their meaning remains uncertain.

His face has pronounced and long golden hairs (held by an elastic at the back), while his beard appears to have two braids. His blue eyes are of the same shade as the sky, and he bears a scar over his right eye. He wears green-bottle pants and strips. As a protection, he wears multiple plated pauldrons and bracers on his arms, all decorated with sumptuous divine knot-works. The man is also equipped with a richly detailed leather armor around his waist, effectively protecting his upper legs and hips. As for his hands, they are so big that he can easily fit a large person's head in them, and the pop it like a grape.

His thick fingers are adorned with a pair of burnished gold rings crafted from the finest of materials. Another notable feature is the hand forged iron pendant on his chest, something that would be very popular among Celtic warriors in particular. He is equipped on his left flank with a holster specially crafted, which allows him to wield the hammer he holds like if it was a handgun. Last but not least, his pair of tanned leather boots that give additional protection while being extremely durable.

As for the hammer itself, the weapon offers a relatively short but richly decorated and refined wooden handle, embellished by a splendid gold pommel, designed with two goats. The head of the hammer is of an atypical and relatively aggressive shape, featuring sharp edges that contrast with the beautiful curves shaping the underside of the hammer. The head of this ancient weapon is covered in carefully carved runes and symbols, and can be recalled by its owner after being thrown, even over a long distance. The hammer has the striking power equivalent to that of a nuclear weapon, which makes it probably the most powerful weapon ever created in the history of mankind.

What kind of warrior wore armor like this? And what was with those tattoos?! All those weird rune-like marks all over his body...

.

..

...

Was that a Hammer in his belt? Wasn't even a very good one at that, all large and blocky, its handle far too short for her liking. What kind of servant had a hammer?! That wasn't a class! She'd screwed up! Her temper slipped its leash, "What is that stupid hammer, anyway?!" she demanded.

"It was a gift from my adopted father, the man who took me in." He ran a finger across its sparking surface, "He gave it to me before he died."

Aha! A clue! "And who might that be...?"

He tilted his head. "Thor."

Illya squeaked.

Oh.

Ohh.

Ohhh!

She'd struck gold after all!

"Servant, Berserker." the merry man intoned, as though reading her very thoughts, "Naruto, at your service." he introduced himself, "You strike me as a calm and reasonable person, Master." His grin chilled Illya to her very core, "Are you?" he tilted his head, further, eyes sparking blue, "A calm and reasonable person...?" Her smile matched his.

"And if I said no...?"

He rose from the ruined couch and stomped his way. Oh gods. He really was tall. Stupid body. She wished she wasn't so short...! Her heart damn near stopped when he paused before her. Loomed over her, now. His forehead touched her. Those lightning blue eyes sparked with glee. "Then I'd say we're in business."

~XxX-xxXXxx-XxX-xxXXxx-XxX~

"So, tell me something, how'd you get adopted by the God of Thunder?" Illya asked Berserker.

Berserker snorted, "What's there to talk about. I was fighting some punk and we ended up getting noticed by old one eye. I killed the little prick i was fighting and passed out from blood loss and woke up in the Old Man's place. Got trained to be better and inherited the hammer when he died fighting ye old snake-pelt." the large man snorted, pulling a bottle of what smelled like alcohol from his belt, "Want some, it'll put a couple inches on your legs?" he offered.

"I'm to young to drink! AND WHY ARE YOU CRACKING SHORT JOKES?!" Illya cried out in frustration.

"Really? They prohibit kids from enjoying themselves?" Berserker asked with a raised brow, "What a waste. Back in my day, if you were old enough to fight and kill you were old enough to enjoy the better things life offered ya." he sighed as he popped the bottle and upended the bottle into his throat, she could hear the contents swirling down his throat, and apparently the bottle was quite full, well not anymore. How the hell'd he drain a full bottle so quick?! Exhaling with a sigh of contentment, Berserker looked at the little girl, "Tell me Master, where the hell we goin'?" he asked her.

"We need to stop by the church and speak with the old priest. Once we finish our business with him, you're free to scout out the competition and even fight a couple of them. However, I forbid you from using your Noble Phantasm unless you have no other choice." she told him.

"Pfft, is that it?" Berserker asked, "Please, the minute I need to awaken old fur ball is the day I drop the hammer." he snorted, "Haven't had a need for the damn bastard in over 250 years when I was alive, don't need him even now. Though I will say using my other skills will be nice for once. Haven't had to exercise my Atmokinesis in a while so that should be fun." he said before sighing, "I'm gonna have to go on a booze run soon." he said pulling out another bottle of alcohol.

Illya blinked, "Ok, I understand everything you just said, but I'm confused as to why you would need alcohol? And what is this about a furball?" she questioned.

"Drinking keeps me calm, and in extension the fox demon I got sealed in my gut. The drunker the bastard is the saner I remain, so long as I drink, you have no problems from either of us, and let me just point out, there has only been one person to survive one of my episodes." he told her as he upended the bottle once more.

"That's two bottles in less than three minutes, how did you survive to live into your second century?!" she asked him.

Berserker swallowed the last of the booze and tossed the bottle, "Plenty of things really. Being a reincarnation of a god, being bathed in a God's blood, being blessed by a God to absorb their immortality, inheriting a Super-weapon that slew an entire race which I then used to wipe out a Pantheon, being exposed to divine demonic energy since I was conceived, take your pick." he shrugged uncaring of how he worded his explanation.

"That's..." she shook her head, "You know what, I'm not even going to dwell on that, we need to get going." she said walking ahead.

"If that's the case, then I can get us there in a jiffy." the blond said as he walked up behind her, and before she could ask what the man was doing, he picked her up and bent his legs and shot into the air, the young girl's scream following shortly after with the sound of crazed laughter joining it.

XxX

"DON'T! YOU! EVER! DO! THAT! AGAIN!" Illya shouted as she pounded her fists into the laughing blond.

"What, you act as if you ain't ever leapt through the air before, it wasn't that bad was it?" he asked as he pulled out another bottle of alcohol and guzzled it down, "Ah, I forget how amazing Thrud was when she made the mead. Wonder if the kid's ever avenged me?" he wondered as he tossed the bottle with a pleased sigh.

"DON'T CHANGE THE SUBJECT! YOU NEARLY KILLED ME! ARE YOU SOME TYPE OF LUNATIC!?" she cried before she paused, "Ah shit, Berserker Class, I forgot, never mind." the little girl grumbled.

Naruto looked at the church, "This is where you wanted to bring us, this hovel?" he questioned, "I don' know kid, somethin's off bout it, and I can't very well let ya go into a place likely ta kill ya." he told the girl.

"I know, I feel the same, but we have no choice. If I don't you will be considered rogue and will be removed from the event of the war." she responded.

"Fine, I'll be out scouting, don't use a command spell if you need me, simply call me." he told her before he pulled off Mjolnir from his belt, and was wrapped in lightning where he then jumped into the air with a crackle of electricity and was gone in an instant.

~XxX-Play AC/DC: Back in Black-XxX~

He could sense them, they were gathered in a group beneath him, and their energies were high. Well, why not make a introduction. Gripping Mjolnir, he surged his power into the super-weapon, and called upon the thunder, dark storm cloud's quickly began to build up around him, lightning crashing through the heavens with explosions that were strong enough the world beneath shook at its power. Then, the ground rumbled as the streaks of lightning begun to race towards the ground, followed by great funnels of cyclonic winds that smashed into the earth without mercy, the pillars of mighty vortex's forming a cage of wind around the group of servants and their master's.

With a swing, Mjolnir was let loose, the mighty hammer smashing into the ground with enough force to crater the earth and throw all the servants off their feet and far off to the further spots of the little lot. With a snort, Naruto followed soon after, his feet slamming into the ground with enough force to cause a explosion of dust, cement, rock and other things that shrouded him from sight, the only visible thing were the sparks of lightning that shot off his body, causing him to glow like a unearthly being. One who wasn't afraid to fight dirty if it called for it.

"Are you not entertained?!" he demanded loudly as he spread his arms as wide as he could while he rose up, "Come now, don't be shy, show yourselves and give me all you got, I'm Servant Berserker, Naruto Thorson, son of Thor Odinson, so I ask again, Are you not entertained?!" he yelled out, his eyes glowing white from the sheer potency of his power, "I won't run, never hide, and never back down from a good fight, hell, if it comes down to it I'll drink you under the table be it one on one or all against one!" he declared, "I'll even let you take the first crack if it so pleases ya, ya sons-a-bitches, so who wants a piece of me?!" he bellowed, lightning arcing off his lumbering form, wrapped around him like a wife would embrace her husband.

With a snarl, he clenched a fist and lashed out, dispersing the dust that surrounded him... and blinked, "Oh what the hell... who the fuck doesn't prepare for an amazing landing like that?" he growled as he noticed the various people sprawled across the ground.

A young woman, a goody two-shoes looking brat, shakily stood up, her blond hair frazzled from the static electricity he had filled the air with, "Well, you certainly live up to the Berserker Class." she grumbled, "What do you want Demigod, a fight, or something else?" she asked... no, demanded.

Naruto snorted, "If I knew what I wanted, I wouldn't have allowed the Grail to Summon me. But, on the contrary to your question, the answer is no." Naruto answered, "What I want is for the remaining Servants to show themselves ta me, so I know who I will be going up against in tha' mean while." he spoke, pulling out a bottle, "Gimme a sec, the booze wore off." he sighed, and popped the cork, a splash of mead pouring out to show how full the bottle was... and then he upended it, the quick draining of the bottle was made apparent as he continued to drink it all without pause, "Ah~ you always did make such good mead Thrudy." he hummed in delight.

Tossing the bottle away, "Now then, you there, girly, what's your name?" he questioned.

"Servant Saber." she answered.

"Pfft, not your class idiot, your name, your actual fuckin' name." Naruto growled, "You scared or something? Come on, you must have been important enough for history to record you into the Throne, so why so scared of speaking your name, I introduced myself because I want people to know who I am, to realize the kind of power I can wield should I desire to actually fight serious." he told her and sighed again, "One moment please." he said holding a finger up... and proceeded to pull out another bottle and drain it, before once more disposing of the bottle, "Sorry, need to keep drinking, else I'll end up a real madman, and believe me, you don't want that ta happen." he guffawed.

Saber narrowed her eyes, "I cannot in good conscience reveal my actual name to you." she responded.

"Hmph, so you are scared. Figures, all you knightly types are too afraid to be yourselves, always trying to make it seem like you never do any wrong." he grumbled, "So, which one are you, Galahad, Gawain, maybe Mordred you strike me as a Mordred... no wait, your to noble to be a traitor. Hmm..." he looked closely at her, and noticed her sword on her belt, "I see... so that's who you are." he smirked as Saber tensed up, "Well your majesty, I humbly bow to your leadership prowess, but no more than that... spineless coward." he growled.

Saber growled in frustration. Who the hell did this punk think that he was, oh, when she got her hands on him, she was gonna-

"Now now, let's not get to hasty friend." a new voice said.

Naruto grinned madly, "I know that voice..." he said happily, "Bryn~!" he cheered as he turned to the newcomer, "I didn't think I would ever see you in a Holy Grail War." he said ecstatically.

"Oh~ Darling, you came as well?" Brynhildr said happily, stabbing her lance into the ground as she embraced her fellow Norse-man, "You look so strapping, which class were you brought in as?" she asked excitedly.

"Berserker, you having that Lance, easy to see which one you were called in as." Naruto grinned.

"Oh dear, I see." she said, slightly worried, "You won't lose control I hope?" she asked.

"No, I have it under control for now. As long as I don't draw on it I should be fine." he grumbled, "So, when did you get summoned?" he questioned her as he sat down, ignoring the recovering Servants around him.

"Ah, Berserker, I have heard of you, a man whom even the God's themselves fear. Someone I was inspired by as a lad to become King of Conqueror's. I am Iskandar, a pleasure to meet the God's-Bane in person." the large redhead said seemingly pleased as he sat up from his spot.

"You are Greek?" Naruto said with narrowed eyes, "I should kill you where you stand." he growled.

Lancer stepped in front of him, "Darling, just this once, let the grudge go, he is being cordial and even brough us here for a banquet among Servants, even if some of us were acting rather childish." Brynhildr explained.

Naruto bristled, but crossed his arms with a huff, "Fine, but I ain't gotta like it." he responded
