The three stood unmoving for what felt like an eternity. Everyone was tense, and Robin's Adrenalin at the lightning strike sobered her mind up enough to realize how serious this was.

The Usopp on the table looked between the two, his eyes and mouth slightly gaping. He looked genuinely shocked by the whole thing too, which was uncomfortable to say the least.

What was going on here?

The obvious answer was that this was all part of some big elaborate trick Usopp was trying to pull. It wasn't unusual for him to prank the rest of the crew, though they were usually innocent and childish.

Nothing this complex.

She supposed he could have used the old model of Nami's Climatac to create the lightning strike and the burst of wind, but that wouldn't explain how he managed to tie a several hundred paged book into the mess with its own unique language and writing style. It would have taken so long to do, far longer than anything their resident sniper would spend on something so trivial.

That didn't even take into consideration the obvious age gap. This Usopp looked around ten years older than the marksman she knew. He was at least an inch taller, and sported several facial scars her Usopp didn't have.

The unfamiliar weapons, the glowing particles finally starting to dissipate around them, and the mark now tingling on the back of her hand.

She knew this was far more than a simple prank.

The question now though, was what in the world could have caused something like this to happen? No devil fruit she knew of could cause something like this.

The Usopp look alike finally took a step forward, pausing when Nami let out an enraged cry.

"Idiot!" Nami shoved at his legs, getting angrier when she couldn't knock him off the table. Soon she was clumsily climbing on the surface with him just so she could shake him senseless by the jacket collar. "What kind of prank are you trying to pull?! You nearly gave me a heart attack!"

A weathered hand swiftly grabbed her own. Before Nami could protest she was being pulled into a tight hug. Nami's eyes widened in surprise.

"It's good to see you alive and well." The not-Usopp whispered barely loud enough for Robin to catch. Finally Nami decided enough was enough, and pushed him away.

"Idiot! We saw each other at dinner you dumbass! Don't think you can pretend to be all sentimental to get out of trouble! Robin and I are going to kick your ass!"

"... Fascinating." It was the only thing Robin could say in response to the odd situation.

"Don't encourage this!" The navigator shouted at her not ideal response.

The door to the library swung open with a loud crack, Zoro panting and holding one of his swords at the intruder, only to nearly lower it at seeing who it was. The not-Usopp smiled kindly at seeing the swordsman.

"Hello Zoro. Were you on watch tonight?"

"What the hell were you trying to do?! Dumbass Long-nose!" Zoro shouted angrily. "You woke up the whole-"

"ROBIN-CHAN!" Sanji's voice rang through the hallway, kicking Zoro to the side so he could leap in and save the girls. There was no danger though, and the entire situation made him look just as confused as Zoro. "Usopp… Nami-swan? Were you the one that made the lightning?"

"No, but this dumbass was!" She moved in to shake "Usopp's" shoulders more, but he dodged this time, hoping off the table and landing gracefully on the floor several yards away.

Way too gracefully to be Usopp.

"Excuse me, but who are you?" Robin steps forward, finally able to get a word in.

"Seriously Robin?! Are you really asking this question?" Nami practically balked.

"Yes, now let him answer." She looked to the newcomer, face stoic but ready to summon her arms if needed.

"My apologies Master. This is my first time being summoned, and I wasn't expecting such a welcome. You can call me Archer."

"Archer….." Robin mused, looking down to the book in her hands. Usopp, or Archer, bowed slightly.

"You look confused. I thought you performed the ritual to summon me."

"I did, but-"

The other boys arrived at the same time interrupting Robin's words. Franky, Brook, Chopper and Luffy all entered the library, some of them more tired than others.

"Huh?" The little reindeer perked up at the odd scent in the air. "Were the three of you working on a new weapon-" Chopper froze, his nose picking up on something strange. He quickly took to hiding behind Franky's leg, fur pricked up from whatever was distressing him.

"What's wrong Chopper-bro?"

"T-that! That's not Ussop!"

"Huh?"

"He looks like Usopp, but he doesn't smell right. He…. I mean, he kind of smells like Ussop, but not at the same time!" The reindeer glanced out from his shield, ducking back at Archer's welcoming grin.

The others immediately turned more hostile, standing ready in case this imposter tried anything.

"Huh?" Luffy yawned, trying to rub the sleep from his eyes. "Chopper, you're talking funny."

"I'm being serious!"

"That makes me wonder, where am I right now…." Archer mumbled. His eyes turned red indicating the use of Haki, face falling immediately. "I'll be right back."

"Oh no! You are NOT running away from this!" Nami reached out to grab Archer's shoulder only for the man to disappear in a cloud of golden dust.

"HUH?!?!" The boys simultaneously freaked out as soon as they saw him vanish.

"USOPP KNOWS MAGIC?!"

"I TOLD YOU LUFFY! USOPP DOESN'T SMELL LIKE THAT!"

"That shit sniper isn't gonna get far! Everyone search the ship! He needs an ass whooping!"

"Hold it!" Robin shouted, finally getting everyone's attention.

"Robin-chan? What's wrong? If that bastard hurt you-"

"You need to calm down and listen." Robin stated, cutting off Sanji and getting her voice back to its normal cadence. "Something is wrong, and that isn't our Usopp."

"Did you hit your head Robin-sis? I'm pretty sure that's him."

"Robin is right! He doesn't smell right!" Chopper shouted trying to get his own point across.

It was enough for Nami to come to her own conclusion.

"Hold on. If that isn't our Usopp, then where is the actual Usopp?"

Everyone glanced around the library, seeing everybody in the crew had gathered except for their sniper. He was missing along with the mystery man.

"Usopp! You here?" Luffy called out to no answer.

"Everyone search the ship and stay on guard!" Nami ordered. "I don't know what's going on here, but whichever one we find I'm going to get answers from one way or another."

"Yes Nami-swan!" Sanji pranced out to do as told.

Everyone else left too, Brook remaining oddly quiet and Luffy looking a bit more serious. It was a strange situation, and one of their Nakama could be in trouble.

Robin had no choice but to search herself. She had the sneaking suspicion that her Usopp was still in his workshop, but Archer could honestly be anywhere.

Activating her devil fruit powers, Robin closed her eyes, allowing multiple sets of eyeballs to sprout all over the ship. Sleeping quarters, lounge area, even the crows nest, she spotted all of her other crewmates, but not the person she wanted to find. It wasn't until checking Ussop's Factory did she spot them both. The entire room was smoking, and Archer was currently trying to slap a younger looking Usopp awake.

Her Usopp.

Without pause she ran down the hallway, rushing past an angry Zoro to the stairs and making her way down them as quickly as she could. The swordsman sensed her urgency, following close behind with his swords drawn.

"That idiot is gonna pay…." Zoro growled.

"Zoro, that isn't our Usopp."

"I didn't say Usopp was paying, I said that idiot."

"Fair point." Robin conceded and put the rest of her efforts into running.

Pushing the door open, the two came upon the sight Robin initially spotted. Archer was shaking the younger Usopp, while the floor smoked only a few feet away from what appeared to be a burn mark.

"Wait, what the hell?" Zoro got his weapons ready pointing them directly at Archer. "Drop him." His voice was low and commanding.

Archer did as told, unceremoniously letting Usopp's head hit the hard wood with a thud.

"Oww…"

"Oh good, he's fine."

Ussop started rubbing a growing bump on his forehead. It took a moment to notice that a shelf had collapsed leaving all sorts of heavy objects all over the floor.

Robin, again, had a sneaking suspicion the thing collapsed when she summoned Archer, and something likely hit her friend's head as a consequence.

"Don't be such a baby." Archer stated.

"You weren't the one nearly struck by lightning, so you don't get a say!" The sharpshooter finally forced his eyes open, eyeballs popping out of his head in shock.

"WHAT THE HELL???" He looked back and forth between a confused Zoro, amused Acher, and an apologetic Robin.

"Oh, I get it! I must still be unconscious, or I accidentally inhaled too much Potassium Chlorate and started seeing things! Why else would I be seeing double? It makes perfect sense! This is definitely not some weird hell or a ghost or whatever. I'm just seeing things!" Ussop was rambling trying to justify everything in his own way.

"Shit, one Ussop is enough to handle…." Zoro sheathed his swords and muttered. Just in time for Luffy and Chopper to nearly plow him over in their rush to get downstairs, soon followed by everyone else.

"Watch it dumbass!" Zoro shouted angrily.

"Ussop!" Luffy smiled, ignoring his angry first mate. "Why are there two of you? Did you eat a devil fruit and didn't tell me???"

"Don't say you see him Luffy!"

"Why?"

"Because that means there really are two of me and I'm not seeing things!"

"Hate to break it to you." Archer interrupted. "But there currently are two of you. Or me, I get mixed up on the matter too."

"HALLUCINATIONS DON'T GET A SAY!"

Archer just grinned cheekily at Usopp's freak out.

"THERE YOU ARE!" Nami slid into the doorframe followed by just about everyone else.

They must have heard the yelling.

"USOPP I SWEAR YOUR DEBT IS-" Nami's words died as soon as she realized there were two Usopps instead of one. "WHY ARE THERE YOU OF YOU?!"

"DON'T ASK ME!"

"WHO ELSE AM I GOING TO ASK, IDIOT!?"

"There are two of me because of you and Robin, remember?" Archer chimed in.

"CLONES DON'T GEY A SAY!"

"Wow, Nami is really mad." Luffy laughed.

"Take this seriously! This is serious!" The redhead shouted back. "There are two Usopps and all you can do is laugh?!"

"Two Usopps means we have two awesome snipers now! And more people to fish!"

"That makes me wonder…" Archer mumbled walking further into the room while Nami was having a fit. Robin watched as he examined the burnt piece of wood flooring, testing it with his hand before lifting it out of place and digging around in the gap it left.

"HEY!" Usopp protested. "Stop tearing the ship appart! Why are you looking in there?! STOP!"

"This would explain it." Archer rubbed the back of his neck tiredly, pulling the object he found up for the others to see. It was a familiar mask, a dinged up yellow one with blue swirls and red lips.

"Wait… THAT BELONGS TO SOGEKING!" Luffy and Chopper both shouted in unison. Their eyeballs were bulging out of their skulls in both shock and excitement. The real Usopp looked like he wanted to die.

"Usopp! Why do you have Sogeking's mask? That's so cool!" Luffy shook his sniper by the shoulders excitedly.

"I can't believe he gave it to you! You're amazing Usopp!" Chopper squealed with big sparkling eyes. Everyone else just looked down at him knowingly, not willing to give the game away, but feeling a pang of sympathy for their young friend.

"I think this or what your summoning circle reacted with, Master." Archer held the mask out for her to see.

Robin was reminded of the instructions she had read, how neither of them understood what a "catalyst" could mean, so they skipped that step.

"Interesting." Robin came over and took the mask in her hands, examining it carefully. "So you're saying that since we didn't use any particular objects as a catalyst, the summoning circle reached out and used the closest one it could find."

"Which just so happened to be in the factory a few floors below you." Archer finished. "If this mask wasn't here, it could have used any number of things on board as a catalyst, giving a completely different result. Given this is also Franky's work space, it could have easily summoned a Rider version of him, if a Rider hasn't been summoned already at least."

Robin paused, analyzing his words.

"Rider."

She recalled reading that word in the book she translated, along with several others.

Rider, Archer, Saber, Lancer, Caster, Berserker, and Assassin.

"Yeah, he's more likely to be summoned int the Rider class. Though now that I'm thinking about it, Nami or yourself were strong possibilities too given your proximity to the summoning circle, but if neither of you were picked then the Caster position is likely filled too."

"Blaster? What's a blaster? Can I eat it?"

"He said Caster, dumbass." Sanji stepped in with a cigarette in his mouth. He paused just before lighting it. "Wait, what the hell is a Caster?"

Ussop was more focused on another point of Archer's words.

"Summoning circle? Wait… you were doing demon summoning rituals in the library?!" Usopp screamed accusingly. His finger started pouting at Robin before a disappointed glare fell on Nami. "Robin I'm not as surprised about, but I expected better of you!"

"Hey! That book promised me any wish I wanted if we summoned a heroic spirit! It sounded like absolute bull, but we decided to try it anyway. How were we supposed to know it would work?!"

"Maybe the fact that the book SAID that would happen!" Usopp stood up face to face with Nami, the two yelling back and forth.

"We could wish to be the richest pirates in the world!"

"At the cost of entering a game we know nothing about?!"

"Do you seriously think our crew would lose!?"

"That's not the point! What if you signed all of our souls over to a devil for all eternity or something?!"

"W-well…" Nami's eyes widened a bit in realization. It seemed her normal thought process was finally breaking through all the alcohol she consumed. Knowing her though, she wouldn't be ready to admit to being wrong just like that. "I-if that's the case then I at least deserve my wish!"

"Actually, it would be Robin's wish. If we can survive to win anyway." Archer interrupted. "She is the one that completed the summoning ritual. The seal on her hand is proof of that."

The others all peered over Robin's shoulder when she lifted her hand, the marks a dark red color and clear for anyone to see.

"Wait, did you tattoo Robin's skin without her permission?!" Sanji shouted, pointing accusingly at Archer.

Of course that was the first conclusion Sanji would come up with.

"Would you stop shouting you shit cook! It's three in the goddamn morning!" Zoro grumbled.

"You're the one that was supposed to be on watch! You let this happen, moss head!" The two pushed the others out of the way just so they could butt foreheads and yell at eachother.

"Hey! If you wanna fight that's fine! Just do it ON DECK!" Frankly pulled the two apart screw\aming over the two idiots. The workshop really wasn't built to house the whole crew at once. The room was cramped and a lot of tools would go flying if a fight between them broke out. At the moment though, that possibility wasn't far from reality at the moment.

Robin caught the small chuckle over the chaos the entire crew had broken into. Archer was watching them all from the corner of the room, enjoying the chaos and smiling fondly.

"Stop laughing you fake long-nose! I'll kick your ass too!"

"I'd like to see you try." Archer snickered.

Sanji abandoned his shouting match with Zoro to butt heads with Archer. Instead of backing down and cowering like her Usopp probably would, Archer didn't even flinch when Sanji's forehead practically collided against his.

"Wait, are we gonna fight?! I wanna fight the new Usopp too!" Luffy latched onto both of them with his stretchy arms, forcing all three to fall to the floor. Archer just lifted his head, still smiling at their antics while Sanji turned his ire on the captain.

"Excuse me Archer, may I ask you a question?" Brook piped up from the hallway. He had remained relatively quiet during the whole interaction, sockets trained primarily on the newcomer.

"Yes Brook. What do you need?" Archer shook Luffy's arm off and stood back up.

"You mentioned having to survive something to obtain this wish. What must we survive exactly?"

"Right. I can answer that question, but not down here. Let's head to the dining area. It's a bit cramped for everyone."

Archer's request was met with little resistance, everyone ready to get out of the cramped factory. Sanji was the only one that didn't take a seat, instead heading back to the kitchen and starting on snacks for everyone. It was currently three in the morning, and despite it being several hours more until breakfast, the cook looked like he needed to busy himself. At least that's what he told Robin when she asked him to join the crew.

Arched stood at the front of the table, while the real Usopp was seated as far away from him as possible. He was still giving Nami annoyed glances, and the navigator was doing her best to ignore him.

"Since I didn't get to introduce myself to everyone, let me start off again." Archer stood up straighter and grinned. "My name is God Usopp, Sniper of the Strawhat Crew. I was summoned by Niko Robin, presumably to fight alongside her in what is called the Holy Grail War."

"So what exactly is a Holy Grail War?" Brook asked.

"It's a battle between summoned servants like myself, alongside the masters who summoned us, for the right to make our wishes come true. If Robin and I succeed, we will each get one wish granted to us. Whatever wish we like."

"And if you lose?" Sanji asked, concern obviously focussed on Robin.

"We will both most likely die."

"Bullshit! She'll have all of us behind her!" Sanji exclaimed.

"Sanji-bro is right! I don't know anything about a wish making grail, but I will sure as hell puns some heads for Robin-sis!" Franky posed triumphantly.

"Depending on how the rules of this particular game will work, maybe." Archer interrupted.

"What do you mean?" Nami questioned.

"Well, this is the first time a Grail War has been held in this world, I don't know if the rules will be different."

Everyone paused for a moment. There was a chance they wouldn't be able to assist at all? That didn't seem right, especially for an event that claims to be a "war."

"I've made my decision." Luffy stands up with a knowing grin. "We are going to this Grail War thingy!"

"Luffy please! It's a war! We need to think carefully about this!" Ussop interrupted. "Wishes are great, but what if this is another world ending scenario? Or a trap!"

"Robin don't do it!" Chopper hopped into her lap trying to hold back tears. "There is something wearing with all this. Please say no!"

"Sorry Chopper." She sighed, patting his head sympathetically. "Once Luffy makes his mind up, it's possible to change."

There was no arguing, and she knew it. Not when Luffy was dead set on a destination.

Besides, the whole idea of the Grail War intrigued her, and she couldn't help but wonder what limitations this wish granting grail would have. There was only one way to know, and that was through participating.

The winds magically changed on Thais own, leading the ship to the Grail's chosen battleground.

A new Grail War would begin soon.

AUTHORS NOTES:

Happy birthday to our long nosed lord and savior!

I'm surprised I managed a part two of any kind honestly. Even if no other servants are revealed I did plan to talk about them in the notes. My next issue with this Grail War is that, I have NOT been keeping up with One Piece since the time skip. I am very unfamiliar with their newer powers (like, I know Ussop uses plants now I just don't know much about it). I also currently have too many other works going on to put much time or effort into this one at the moment.

THEREFORE! If anyone that is better equipped with knowledge of One Piece fighting techniques and stuff wants to take over this idea they are more than welcome!

Without further ado, here are other concepts I was playing with:

RULER CLASS: (accidentally had the class named mixed up with avenger at first. Thanks all for pointing it out)

-Gol D Roger being brought back as an overseer to the games would be sick. Just sitting on top of an execution platform or something and enjoying the spectacle, bringing the hammer down when rules are broken. Maybe he sticks a limit on the number of people that can accompany each master.

SABER CLASS

-I'm honestly tempted to put Tashigi as the Saber servant. Her knowledge of weapons could transfer into a skill that identifies Noble Phantasms on Sight, and her lack of screen time could leave a lot of room for creativity on her fighting.

LANCER CLASS:

-It has to be Whitebeard. He wielded an actual Lance and he's awesome. Maybe his wish would be to get Roger to come down from overseer and actually fight him?

ARCHER CLASS:

-I just love Usopp and Robin together since I think tgry could pull off a lot of cool team attacks together. Like usopp throwing a crap load of firearms in the air and Robins summons a whole lotta hands to start shooting? That would be cool.

-Also possibilities for Usopp's Noble Phantasm are endless. His 10 Ton Hammer, his bag having infinite holding capacity, "Usopp Spell," maybe even one similar to Rider from Fate Zero where he can summon up is now 8,000 followers to fight with him.

RIDER CLASS:

-Stuck between Hancock and Tom. The thought of Franky's dad figure just driving a flying sea train around makes me happy.

BERSERKER CLASS:

-Fisher Tiger. He died still unable to forgive humans, and him coming back as an uncontrollable rage beast would be tragic.

CASTER CLASS:

-Portgas D Ace. He throws fire from his hands so that seems Caster enough to me lol. Plus a puffy/Ace reunion would be adorable.

ASSASSIN CLASS:

-Kind of love Leo the dwarf being Assassin. Small and unassuming, maybe with Law having become his master after a series of weird events. Don't want to give the Strawhats too many allies.

Also, Buggy needs to be there. I love Buggy, he'd make such an idiot master.
