(Earth, Southern California, San Diego. 1004 years ago)

“How did I let you idiots talk me into this again?”

The five people were walking out the hotel that we had booked for the duration of the San Diego Comic Con. They had come all the way to America from Britain to get in.

“Simple we needed a fifth person to go with us to America’s Comic Con and Tom was sick.” Carl explained dressed as Ezio from Assassins Creed “So you were our other choice-”

“Don’t say my name call me by the name of the person I’m dressed as”

“Fine Gilgamesh, are you happy?” Carl asked annoyed

“Very” Gilgamesh replied

“So why did you pick Gilgamesh from Fate/Stay Night?” Patrick asked dressed as an ODST “Isn’t he the bad guy?”

“Hey my cousin is dressed as Lucy from Elfen Lied and I don’t hear you giving her any shit” Gilgamesh snapped waving his Ea replica at him angrily.

“Yeah well I’m older and smarter than you” Lucy quipped

She was wearing a pink wig with cat ear like horns and was wearing a pair of contacts that changed her eye colour to a lighter shade of red. She was wearing a white t-shirt and short jeans with trainers.

“Shut up Lucy or do want me to call you by your real middle name Maria” Gilgamesh taunted

“For the last time my middle name is MARIE NOT MARIA” Lucy yelled angrily

If she had actual vectors Gilgamesh probably would have been pounded into the ground for that. She hated it when people changed her middle name from Marie to Maria for a reason he had never found out, all he knew was that it wound her up to no end which was great for amusing himself during the boring family reunions.

“Oh relax and keep your voice down we’re here” Gilgamesh said as they arrived at the security gate “Hold on a sec where’s Steven?”

The others all stopped and looked at each for a second before Patrick spoke up.

“He’ll be along, we said we’d meet him later by the food court” he answered “He’s putting the finishing touches on his Master Chief costume. He custom ordered the armour apparently”

“Whatever” Gilgamesh snorted derisively

With that the four showed their tickets and went through the security gate and entered the convention centre. It was huge there were thousands of people going back and forth between different stalls and there multiple levels to the complex as well.

“Hey me and Patrick are going to go check out a few of the stands what about you?” Carl asked

“I’m going to stick with my younger cousin” Lucy said “I promised auntie that I’d keep him out of trouble.”

“Ok see you later then; we’ll meet you at the food court around noon”

Carl and Patrick then melted away into the crowd leaving Gilgamesh and Lucy alone with each other.

They started walking around and browsing several random stalls even one with a few manga on it. After they had finished browsing they went up to the second floor, third to Americans. They walked over to the railing and Gilgamesh leant backwards against it still not letting go of Ea.

“So where did you get that Ea replica?” Lucy asked

“I got it at a weird looking store back home. It had all sorts of random crap in it and I wasn’t interested at first but he offered me the Ea replica dirt cheap. Only fifteen pounds from the usual twenty four.” Gilgamesh replied with a smirk

“Wait did the old guy wear a hood and have glowing red eyes?” Lucy asked

“Yeah” Gilgamesh confirmed turning his head to look at her “Why do you ask?”

“Because that’s the guy who sold me these replica clip on Diclonius wig, pink contacts and horns” Lucy explained

“Hmm that’s weird I…hey do you hear something?” Gilgamesh asked

“Look at Ea” Lucy ordered quickly

He did so and saw that a white glow was travelling from Ea and was crawling up his arm.

“Put it down” Lucy demanded

“I can’t my hand won’t move” Gilgamesh replied with a panicked tone.

The white glow got faster and panicked Gilgamesh took a few steps backwards and wound up falling backwards over the railing. His cousin reached out for him yelling his name, even as the white glow continued covering his body as he fell. Then all of a sudden Ea stopped in mid-air and Gilgamesh hung there with it. The white glow shot up what looked like an invisible hand, no not a hand a Vector, a Diclonius Vector.

Soon the glow covered them both and with a large flash of light and clap of thunder they vanished from Earth all together.

(Equestria, Everfree forest, 1004 years before present)

A large flash of light illuminated the darkness of the Everfree forest. A young man with blonde hair and red eyes was dropped into the clearing. His golden armour clanged against the ground. A young woman dropped on top of him a few seconds later causing his armour to clang again.

“Aggh damn it” Gilgamesh cursed as his cousin stood up off of him.

“Where in the hell are we?” Lucy asked wiping some mud off of her.

“Don’t know a forest of-”Gilgamesh paused as the ground shook.

*THOOM**THOOM*

“What the?! Is this an Earthquake?” Lucy asked struggling to keep her balance

*THOOM* *THOOM*

“No its sounds like footsteps” Gilgamesh said trying to keep himself from falling over.

Suddenly the treeline parted revealing a gigantic purplish bear with fur that looked like the night sky, and was partially translucent. It was absolutely massive and roared down at them.

“HOLY SHIT WHAT THE HELL KIND OF BEAR IS THAT?” Lucy screamed as she ran off her cousin running as fast as he could behind her.

“I DON’T KNOW JUST KEEP RUNNING” Gilgamesh yelled as a massive paw slammed into the ground behind them and scraped it up.

The colossal night sky looking bear gave a roar of anger and frustration at its prey escaping and gave chase, lumbering through the forest with massive strides. They dodged several more attempts by the bear to grab them and eventually saw a rocky cliff face with a cave ahead.

“Hey there’s a cave we should be safe from that thing in there” Lucy yelled pointing at the opening in the cliff.

“Right” Gilgamesh ran faster trying to keep up with his cousin.

Unfortunately the bear was one step ahead of them and slammed a paw into the cliff, causing a rockslide which blocked the entrance to their potential escape passage. The two skidded to a stop in front of the rubble and turned to face the bear now cornered by it.

“Is this where we’re supposed to die?” Lucy asked with fear “Eaten by some giant bear in some weird forest far away from home?”
Gilgamesh growled and stood forward and pointed Ea at the bear. Strangely the replica of the sword of rapture felt heavier than it once did and now seemed to be shinier almost like it was metal instead of plastic.

“What are you doing?” Lucy screamed “Are you crazy?”

“I know it’s futile” Gilgamesh replied “But I’ll go out fighting no matter how futile it is”

The bear growled almost like it was angry at Gilgamesh’s defiance. Suddenly in that moment, the segments of Ea began spinning faster and faster, and the wind howled along with it. A shockwave of wind was sent out of from the weapon not only causing the giant bear to stagger backwards slightly, also sending a tremor through the earth below them.

The drill shaped sword took on a crimson glow that forced Lucy to squint.

“My cousin has been there for me all my life and I will not allow some oversized throw rug to harm her” Gilgamesh yelled and instinct took him over like he was being guided by something “ENUMA ELISH”

He swung the sword downwards and it released a vortex of crimson energy that erupted at the bear. Within the space of a second, the bear was missing its top half. After a few moments the bear’s remains slammed down into the ground causing a final earthquake with its death.

“That was….But how did you?” Lucy was lost for words.

“I don’t know how but, somehow I have the powers of Gilgamesh.” Her cousin said “It’s like I felt something guiding me and Ea responded.”

The sword in question had vanished into a flurry of golden particles.

“And remember back at the convention centre when I was falling, you used a vector to grab Ea and save me.” Gilgamesh pointed out

Lucy tilted her head and saw indeed that she possessed four invisible hands. She sent one out and experimentally tore off a branch from a tree and with the vector held it out in front of her.

“This is…..unreal” Lucy gasped examining the branch “How is this even possible we were just cos-players a few minutes ago what is going on?”

“I have no idea” Gilgamesh said “But maybe if we find a way out of this forest we can find some answers”

“This….all of this is completely impossible” Lucy cried again as they started walking

“So you said” Gilgamesh replied as they tried to find a way past the giant star bears corpse.

(Equestria, Castle of the Royal Pony Sisters, 1004 years before present)

Princess Celestia, Diarch ruler of Equestria who raised the sun to bring forth the day, along with her sister Luna who raised the mono to bring forth the night were currently sitting together in the throne room. They had awakened Celestia from her slumber because of an emergency. The captain of the guard Steel Spear was stood there standing at attention.

“Now Captain what so important that I had to be roused from my sleep?” She asked patiently

“My apologies your highness but we thought that both of you needed to know that an Ursa Major was sighted moving in the forest” the captain said

“I see” Celestia said gravely

“Tis not good sister” Luna said “First we must deal with Tirek who is still at large and now we must deal with an Ursa our resources will quickly become strained with all of these crises”

Celestia looked thoughtful for second.

“Well maybe we can-” Celestia paused as a tremor shook the castle

“It came from that direction” Celestia galloped towards the balcony and looked out towards the forest.

She could just make out the Ursa Major which was illuminated by a scarlet glow coming from below it in the forest, as Luna and the captain joined her.

“Could somepony be trying to do battle with that Ursa?” Luna asked from beside her “Tis foolishness, we stop them before-”

Suddenly Luna was interrupted as the scarlet glow condensed and large beam blasted the Ursa Majors Head and shoulder away as if they had never existed in the first place. The three were left dumbstruck.

“How in Tartarus could anypony besides yourselves possess such monstrous power your highnesses?” the captain asked breathlessly

“I do not know” Celestia replied gravely “But I intend to find out”

With that she and her sister took flight into the night sky heading towards the location where the corpse of the Ursa had fallen.

(Equestria, Crystal Empire, 1002 years before present)

Much had happened in the two years since Gilgamesh and Lucy had landed in Equestria. After he had saved himself and his cousin Lucy from the Ursa Major with Ea, he had been confronted by two Alicorn sisters called Celestia and Luna who ruled Equestria. They raised the Sun and Moon to bring the Day and Night respectively.

His cousin had spoken to them when they appeared before the two, she was the more rational one and thanks to her they had managed to avoid a conflict, that time at least. A bit later they began a journey across Equestria searching for a way home while mastering their newfound abilities; they got into several fights that earned Gilgamesh great renown. Including slaying the so called Dragon King, the killing of the Great Alpha Diamond Dog, the extermination of the Windigo invaders and more. Not that his cousin had not done her own deeds of course, in fact she had been instrumental in the Dragon Kings death, without her Gilgamesh would have had a more difficult time delivering the killing blow.

But she was admittedly more humble and shrewder than he was. While he revelled in the attention and admiration that he received from the masses. His cousin preferred to stay in the shadows. They now had full control of the powers they had been afforded and she was more focused on trying to find a way to get them both home.

She sincerely was not jealous of the fame that the deeds the masses attributed to him alone gave him. She had always been humble like that but he was surpassed that she didn’t resent him for it. When he had asked her about it she replied that they were family and there was no time for petty jealousy over something as minor as fame. The most important thing was going home.

Gilgamesh chose to stay out of the way of her research and to aid her when she asked for it. She was the academic he was the muscle of their operation it was a relationship that worked. Especially when scouting out ancient ruins that she thought might hold artefacts or clues on how to get home.

Right now though Gilgamesh was revelling in his latest conquest. He was now the ruler of the Crystal Empire after slaying its King Quartz in battle and being named the empires new king. Now he and his cousin had a vast library and the resources of a kingdom at their disposal.

While some might say that he was a hero, Gilgamesh himself disagreed. He was neither a hero nor a villain he transcended such things. He did what he wanted when he wanted. The only exception to that rule was requests that were made by his cousin. She was the only one he would acquiesce to.

“King of Heroes and now ruler of the Crystal Empire” Gilgamesh chuckled to himself aloud as he sat on his Golden throne in the crystal palace with his eyes closed “Not a bad if I do say so myself. Now I wonder where it is that my dear cousin has gotten to. It’s been a while since I’ve heard from her”

“She has been locked away fiend a fate thou shalt share with her” familiar booming voice said.

Gilgamesh opened his eyes to see the Lunar and Solar Diarchs standing there in front of him, in their own battle armour that coverd them head to toe. He noted that Luna’s Horn was glowing, clearly she was charging some type of spell

“So Luna, still using that Royal Canterlot voice are you?” Gilgamesh asked with boredom “No matter what is this I hear about my cousin?”

“She has been locked away in Tartarus Gilgamesh” Celestia explained with her Horn lowered with a spell prepared.

“And you think to make me join her you petty quadruped?” Gilgamesh asked “A place like Tartarus cannot hold me you know this by now. After all you did attempt to banish me there after I killed your precious sentinels who dared to stand in the way of my claiming of the Amulet of the Stars or how about those foolish lunar agents who tried to stop me from claiming the Moon Crystal? Time and again you have tried to banish me and you have failed each time. So why not give up already? Release my cousin and I will show mercy to your subjects when I take my vengeance for this insult.”

“You are in no position to make demands Gilgamesh for we have a spell that can imprison even you” Celestia threatened

“We shall see” Gilgamesh replied standing up

The space above and around him began to ripple as his Gate of Babylon activated; various swords, spears and axes appeared in mid-air awaiting command. The spell on Luna’s horn suddenly brightened gaining a whitish blue glow.

“Sister it is almost complete” Luna informed her sister.

“I am ready Luna” Celestia said as she threw up various magical barriers and shields.

Suddenly Luna’s size was reduced slightly, and the spell glowed brighter.

“What’s this?” Gilgamesh raised his eyebrow “Am I supposed to be intimidated by this display?”

“Thou shouldst be fearful fiend” Luna growled focusing the spell “I have sacrificed half of mine own Alicorn essence to power this spell. A forbidden spell of sealing that can imprison even thee”

“We shall see about that” Gilgamesh replied “BEGONE”

The golden weapons all fired at the mares, shattering all but one of the barriers, the weapons impacted against Celestia’s final barrier. She sweated visibly as she strained to keep the shield up against the onslaught of Noble Phantasms.

“I see a soul shield” Gilgamesh observed as his gate began firing at a more rapid pace “You are desperate to get this to work aren’t you? If my Noble Phantasms shatter that barrier then your very soul will be in jeopardy Princess Celestia”

“I would sacrifice my very being to protect the ponies of Equestria” Celestia gasped out

“Then I will allow you that honour princess of the sun” Gilgamesh said as his weapons picked up pace.

A crack formed in Celestia’s barrier as the sweat began pouring down her face.

“LUNA” she screamed her horn and her body burning in agony at trying to hold the dangerous shield spell.

“Tis completed” Luna yelled as her the spell became a kaleidoscope of colours “NOW FIEND WE SEAL THEE SLEEP FOREVER MORE”

She fired the spell which erupted from her horn and became bigger than she was. It soared through the air unimpeded by the weapons that went through it.

“What’s this? Impossible” Gilgamesh growled but before he could summon a Noble Phantasm to defend himself the spell impacted with him and began encasing his form in a thick crystalline substance “THIS NOT OVER I WILL RETURN, THAT I PROMISE YOU”

Gilgamesh declared this as he was completely encased in the star patterned crystal. For good measure Celestia conjured a pair of chains which wrapped around the crystal and were locked with two padlocks one with Luna’s cutie mark engraved on it, the other with Celestia’s. Two keys with sun and moon shaped handles appeared hovering Celestia’s magical grip.

“With these two keys the chains should ensure that Gilgamesh remains sealed for a very long time” Celestia said

“We cannot simply dump Gilgamesh in Tartarus” Luna exclaimed “You know as well as I that the darkness of that realm would degrade this spell faster and all of this would be for nought”

“You made a great sacrifice Luna” Celestia nuzzled her sister consolingly “But while we may bought Equestria peace, when it comes to Gilgamesh we may have only delayed the inevitable. He will return eventually, even now I can feel his powers attempting to break the Alicorn crystal. But when he so casually slays ponies and others alike who stand in front of him and with his murder of King Quartz and his usurping of the Crystal Empire he left us no choice but to stop him”

“Perhaps in the future a greater solution will have presented itself” Luna replied

“Until then all we can do is watch over him and hope” Celestia said

“What of his cousin in Tartarus?” Luna asked “When he does free himself, should he find her deceased there is no telling what he might do. It could spell the end of Equestria”

“Luna the inside of Tartarus is more like a prison with lots of separate cells. Lucy is in no danger form the others that are kept in there” Celestia explained “And time does not pass like does out here. For every century that passes out here but one year passes in Tartarus. In order to prolong the prisoner’s punishment.”

“I suppose all we can do now is wait” Luna said

“Yes wait and watch over Gilgamesh” Celestia replied “Hopefully by the time he breaks free we can let his cousin out to reason with him.”

“Sister pray tell, what is the name of the pony that is to succeed Quartz as ruler of the empire?” Luna asked

“I believe his name is Sombra” Celestia replied.

Author's Note

So I thought I'd have a crack at this costumed human gets character powers in Equestria thing. I apologize for my spelling and grammar, if I've missed anything please don't hesistate to point it out. I hope it isn't so bad that you can't read this thing.

Also Surpassing All Others by Zarallan has nothing to do with Return of the King and I have no issue with it whatsoever. We simply came up with similar ideas around the same time.
