Inspired by: One Piece: A Smash Adventure

It was a peaceful day in the Thousand Sunny. The Straw Hat pirate crew were sailing with not a worry in the world. After the whole battle against Gekko Moriah and his giant army that what the crew wanted the most: Peace.

Right now, their new crewmember, the musician Brook was playing a nice tune with his violin. Something very nice and fine.

''I don't ever thought I would say something like this but…having a musician is pretty good.'' Said Sanji with a laugh

''Yeah. Who would imagine we be sailing around without some sound? Although I consider myself a musician too.'' Said Frank putting his guitar on his lap. However, Sanji picked the instrument before Frank started another one of his songs.

''Not at the moment you frecking pervert. Your songs are a mess that nobody can understand.'' Said Sanji.

''Whaaat. How can you say that too my art?'' Asked Frank all shocked.

''Your songs made no sense. You make them out of nowhere and sincerely they sound alike.' Said Sanji all serious.

''I like your songs Franky.'' Said Robin to the shipwright.

''Really? Well thanks girl.'' Said Frank with a smile.

'Aaaaah Im sorry Franky. If Robin-chan like your songs than I also like them.'' Said Sanji apologizing to Frank immediately

''You are a real sell out.'' Thought most of the crew. Is just a pretty girl say something and Sanji is all in favor.

''Hey what with all the noise?'' Asked Zoro waking up from his nap

''Uh, good morning Zoro?'' Said Usopp a little surprised that Zoro was still sleeping.

''Is still morning? Wake me when is dinner time.'' Said Zoro trying to sleep again.

''How about never.'' Said Sanji all irritated.

''Sanji please.'' Said Chopper trying to make the crew stop fighting.

''Alright chooper.'' Said the cook smiling at the reindeer

''Hey everyone.'' Said Nami getting to the deck of the Sunny

''Nami.'' Said most of the crew that were relaxing there.

''Nami-san.'' Said Sanji already in lover mode.

''Where is our captain?'' Asked Nami seeing that Luffy wasn't present

''Still on the lion head. I think he has been there since morning.'' Said Usopp

''I guess trying to find the next island.'' Said Sanji

''Jeez after all that crap that Moria did to us he sitlt wants more.'' Said Nami with a face palm.

''Well it appears I chose the right crew. Yohoho.'' Said Brook laughing.

Soon Nami walked over to where Lufy was and he was still looking at the sea in joy.

''Hey Luffy.'' Said Nami

''Nami. Did you see any island? Im so bored.'' Asked Luffy with a cheerful smile.

''No. And besides our destination is bid deal. The red Line is huge and after that we have to pass Fishman Island.'' Said Nami telling him to be patience

''I know but I want to do something now.'' Said Luffy acting like a little kid.

''Oh boy he is at again.'' Said Usopp

'Great.'' Said Sanji irritated. He hates when the captain like that.

''Come on guys. Let's find some island.'' Said Luffy with full of excitement

''Pass.'' Said Sanji, Frank, Usopp, Nami and Chopper.

''Aaaah come guys. Where are your pirate spirits?" Asked Luffy

''Shut up.'' Said Zoro tossing a bear mug at the captain.

''Yeah we just survive that whole nightmare at Thriller Bark.'' Said Usopp

''Let's enjoy the day. Have some tea and read.'' Said Robin

''Agreed and soon we can all have some good tunes to listen too. Yohoho'' Laugh Brook.

''Man, this suck.'' Said Luffy all depressed.

''If you are so bored then go play with the new board game that I invited. Is on the workshop, but you have to find it first.'' Said Usopp with a smirk

''Really thanks.'' Said Lufy storming out to find Usopp game.

''Is that board game even real?'' Asked Robin

''No, I invented right on the spot.'' Said Usopp with a smirk

''Nice one man.'' Said Sanji fist bumping Usopp.

Suddenly after Luffy spent 4 hours looking for Usopp awesome board game but found nothing. He decided to ask the sniper where it was when suddenly he saw something. Something big and white in the middle of the ocean.

''Hey what is over there?" Asked Luffy to the entire crew. At first, they imagined it was nothing but then…

''What are you…'' Said Nami who was skeptical at first but then was with her eyes in shock alongside everybody.

''Are you serious?'' Asked Zoro in pure shock.

''Am I dreaming?" Asked Frank rubbing his eyes.

''No, it can't be.'' Said Robin confused.

''How is that even possible'' Asked Sanji

''AAAAAAAh'' Scream Chopper, Usopp and Brook in horror.

The pirates were seeing at North a huge white door. Like in the middle of the ocean for no reason. Maybe it was a prank but in the Grand Line you never know what can happen. The entire crew was in pure shock, they imagined after fighting Zombies things would be easier but no.

''A door? Here.'' Asked Luffy

''Why there is a door in the middle of the ocean?" Asked Zoro picking his katanas.

''Im having Ennis Lobby flashback bro.'' Said Frank

''I don't know why but I am gettings chills just by looking.'' Said Sanji with a bad feeling. Robin was paralyzed looking at that anomalies while the cowards of the crew were hiding inside of the ship.

Luffy who was begging for an adventure had suddenly a huge smile on his face.

''Let's go there.'' Said Luff

''No.'' Said almost every one of the crew. No way in hell they would pass that door that lead to god knows where

''Let's move the ship to a south west position. We can escape the course and not stop by that door.'' Said Nami already looking around and giving orders.

''Right.'' Said most of the crew moving.

''Ah man. I really wanted to see what's behind that door.'' Said Luffy all sad.

''Luffy come stop trying to put us six feet underground.'' Said Usopp in anger

While the crew was doing this plan, they move to another way in hopes to escape the contact with the giant sinister white door.

''Is working?'' Asked Usopp with hopes. It seems at first but then the ship was now going back to move toward the door, but it felt like it was being pulled.

''No. We are back on track.'' Scream Nami in horror

''We are being pulled over.'' Said Robin.

Soon something more sinister happen. The giant door open and inside there was only darkness.

''The door is opening.'' Said Chopper seeing the scary now open

''And it doesn't look that good to begin with.'' Said Frank seeing only darkness

''So, lets fight this door.'' Said Luffy ready to fight alongside Zoro and Sanji.

''Never fought a door before.'' Said Zoro interested

''Well this something you don't do every day.'' Said Sanji making a cigarette.

The Sunny was getting closer and closer to this door. Luffy, Zoro and Sanji were ready to brawl while most of the crew was dubious to what was about to happen.

''We are getting closer.'' Said Zoro

''Is over. We are doomed.'' Scream Usopp in tears.

''Stop talking!" Scream Nami also in tears.

''No, I just became free recently. I am too beautiful to die.'' Said Brook

''Nobody is dying. Zoro, Sanji lets fight.'' Said Luffy putting his hat and ready to beat the door.

''Right.'' Said the rest of the monster trio.

''Let me assist too.'' Said Robin getting in position

''A bro wouldn't leave his captain behind.'' Said Frank preparing his handgun.

The pirates were getting closer and closer the door seemed like the size of a giant, how they spotted that from miles away? Anyway, they were ready to rumble.

''Alright guys let's do it. Gomu Gomu no…'' Said Luffy ready to attack

But then door with an incredible impulse pushed the thousand Sunny to inside of her and then close its door. After shutting it down the mysterious giant door finished from the eyes of the world. He got what he need it.

Inside the door

The pirates were covered in darkness. Again, remind them of Thriller Bark, Frank activated the Ship lighting system to make sure that they have visual of everything surrounding them. They saw only darkness inside, there was no ocean, no sun, nothing. They were in pretty much pitch black and none of them like that, not even Robin.

''Wait did the door did to us?' Asked Chopper hiding (in the wrong way) behind the main door

''We are dead.'' Said Usopp in tears. This is it; he went to the afterlife.

''Stop being such a baby.'' Said Zoro irritated, they weren't dead. Or they were?

''You know for a white door there is sure a lot of darkness inside it.'' Said Sanji looking around. Are they really sailing in pure black?

''I agree.'' Said Robin

''Maybe we aren't dead. Maybe we are in another part of the Grand Line.'' Said Nami

''Exactly, you are all in a place where time and space are none existent.'' Said a new voice. And it sounded like an angel.

The straw hats looked around confused. That didn't sound like any of them, but who was it.

''Who said that?' Asked Usopp all nervous

''Show yourself.'' Said Zoro ready to cut something

''Yeah. If you wanna fight than show yourself.'' Said Lufy ready to rumble

'' Very well.'' Said the voice

Then suddenly appeared in the ship a bunch of white pixels that when coming together made the appearance of a beautiful woman. Blonde hair, appearance of someone in her 20s and her face covered in some kind silk made scarf.

''Wow.'' Said most of the crew in shock of the new arrival

''She is…beautiful.'' Said Nami in pure admiration

''Melori. Melori. Melori.'' Said Sanji in pure love mode

''Who are you?" Asked Frank

''My name is Charmeine and I need your help.'' Said the new arrival.

''Our help?'' Asked Luffy confused. He is always eager to help but why this time.

''Exactly for you see I come from another plain of existence that watch over thousands of worlds. We are reaching a crisis that could destroy most of them and we believe that you and your crew are the best suited to help.'' Said Charmeine.

''Wait really.'' Asked Nami in pure shock alongside most of the crew. They didn't expect someone watch over worlds to ask them for help. After all they are pirates, they are not the good guys.

''Well thanks. My crew is really strong, and I appreciate you praising us. So ok Chamry, we will help you.'' Said Luffy laughing.

''He is just accepting this on the spot!"' Thought most of the crew in horror. Luffy accepted another dangerous mission

''Now wait a minute. Im sorry miss Charmeine but before we go to what kind mission you need us, is better for you tell us who are you and what mission is that.'' Said Robin reaching a good point. Soon the celestial being started to talk

''Fair enough. For you see I am come from a plane of existence where my people called The Watchers observe and analysis diverse world. Yours being one of them, for centuries and centuries we lived in peace and Harmony. However, a few years ago our master has gone corrupted and threaten to destroy most of the worlds that we Watchers tend to protect.'' Said Charmeine explaining her story who grabbed the interested of all the pirates. The idea that their world was being watch by being like her is surreal but most surreal was that her master was eager to destroy these worlds

''Your master'' Asked Chopper afraid to ask

''Yes, the Polygon man. He was once a being who swore to protect all the worlds.'' Said Charmeine.

''What happen to him? To go from good guy to I want to kill everyone.'' Asked Frank

''He became corrupt by all the bad things happening in all the worlds. He then decide that we should eliminate all the worlds with the biggest level of sins and dark energy. No matter the innocent life's, he prefer that all of them must die.'' Said her.

The Straw hats were shocked to hear that. This Polygon man was ready to commit genocide of billions of people for what he believed was the right choice. That couldn't be real.

''How can someone become so evil?" Asked Nami trembling

'Maybe he didn't eat proper.'' Said Luffy

''It wasn't that" Said Usopp in pure fear. Like hell he want to meet a guy like that.

''So, where do we come around? What do you need us to do?" Asked Robin

''For you see I need you all to go to different worlds and help a certain individual reach their goal. Once they reach, we Watchers will receive something called a melody which is a powerful Jew that when all combine it can counterattack the Polygon man. This is our only choice.'' Said Charmeine begging for help.

The crew was shocked when they heard that request. Did she said other worlds, melody's and people? What that hell was going on. They never expect that sail to find the One Piece was going to be so complicated as that.

''You want us to go to different world and help people complete their objectives so you can collect this melody's.'' Said Nami trying to wrap her head around that.

''Yes, once these certain individuals have reached their goal, we will sent you all to the next world. If you are wondering, we need 8 melodies to combat the Polygon man. The most important thing of all is to find the special individual.'' Said Charmeine explaining her rules.

''So, we can't go and explore those worlds for ourselves?" Asked Luffy all sad.

''In a way that you can understand no. You be sent to a specific area, but I guaranteed that these areas are filled with the most amazing thins ever discovered.'' Said Charmeine

The Straw Hats all looked at each other and imagined that. If they did this mission, they would go to were no other pirate had gone before. Other worlds, adventures never seen no even by the king of the pirates and a chance to help others. Luffy put his hat on his head and put his usual smile.

''Alright let's do it.' Said Luffy and most of the crew went along.

''Sure, should say sooner.'' Siad Zoro now excited to fight new things.

''But hey a random question. Those all this world are gonna be like ours or they are gonna be like pits of lava or fish talking backwards?" Asked Usopp confusing the crew

''Yes, all the world are very different from yours. But the main factors will be very similar to yours.'' Said Charmeinie

''I see.'' Said Robin hearing all that.

''Do they see us like we are?" Asked Nami

''Well the most of them will see all of you as they please. So, don't worry about your appearance.'' Said Charmeine

''Oh, so nobody is gonna run from brook.' Said Chopper with a laugh

''You know how sensitive I am from my appearance.'' Sais the skeleton all sad.

''Not the moment for this. I we better get a fat treasure once we did all this crap.'' Said Nami to Charmeine

''Will grant any wish once you save us. Please Straw hats we need you all to save the Multiverse.'' Said the angelic being now in tears.

Luffy and the company saw the new arrival crying and begging for help. That's enough to get the whole crew to join

''Well count me in. If I get to fight this Polygon Man I will save as many worlds as I can.'' Said Luffy excited.

''If there are things that I can cut, I am eager to join.' Said Zoro.

''Well I am going to regret this. But maybe I find some treasure along the way. Count me in.'' Said Nami with a grim

''Me scared please. The great captain Usoppp never run from danger.'' Said Usopp with an awesome pose only to have his leg shaking.

''This monster is gonna destroy worlds full of ladies. As a gentleman I can't allow that.'' Said Sanji.

''I wanna see the different worlds and help out those in need.'' Said Chopper

''learning history from this place will be fascinating. If I get books from their worlds, I will be so happy.'' Said Robin eager to join.

''Well I might get a gig of looking on how their technology is. Maybe they need a little lesson on how to be Super.'' Said Frank putting his glasses.

''I will follow my captain to any world that he goes.'' Said Brook

Luffy saw the entire crew eager to join in this new adventure. They were about to go full on this one.

''Alright let set said'' Said Luffy

''Yeah.'' Scream the crew

Charmeine saw the pirates all happy. They were told to save the multiverse and they see as just a normal thing.

''I appear to have chosen wisely.'' Thought her with a smile

''But hey charmey will come with us?" Asked Luffy

''Yes, our ship is big enough to have another person.'' Said Frank

''I cant I need to go back as my duty as a watcher. But me and my friends will be watching over you all.'' Said her

''Ok. Since everything is settle, LETS GO!" Scream Luffy

''You got it captain. Is time for those worlds meet the super awesome way of The Thousand Sunny.'' Said Franky doing his pose

''Yeah Super.'' Said Luffy, Chopper and Usopp

Charmeine only saw that goofiness and made a small smile.

''You seen super chill for someone who watches over everything.'' Said Nami

''Well I choose you all after months of research and after you defeat the pirate Gecko Moriah it was enough for my colleagues agreeing with my choice.'' Said her with a smile beneath her scarf.

''I am feeling with honor that others had chosen me of all people to save worlds.'' Said Brook in tears.

''I am doing this for you my lovely Charme-chan.'' Said Sanji with hears on his yes

''Once I am done with this polygon man nobody can deny that I am the best swordsmen of the entire multiverse.'' Said Zoro

''How brutal can you be?' Asked Nami

''Well I am going to be opening the first world portal. Good luck.'' Said Charmeine disappearing of the ship and soon enough in the mid of that intense darkness a portal open. The Straw Hats knew what to do next.

''OK. Let's set sail''. Said Luffy in the head of the Sunny ready to sense some adventure.

''Right.'' Said the crew sailing and soon enough they disappear to the first world

Charmeine was floating in the darkness seeing her choices going away. She hoped that they survived this mission, each world will get more difficult. If they fail is doom.

''Goodbye Straw Hats. I am really thankful. Because if not the whole multiverse including your world will leave existence.'' Said Charmeine disappearing as the Thousand Sunny reached their first world.

Well here we are. So, this is the only chapter that doesn't feature a PlayStation world. The ideas of Watchers is a usual one. The Watchers were my idea, I need some kind force to enlist the Straw Hat to go to the worlds. I like that Polygon man is like master Hand of Smash Bros, the bad thing is that All Star didn't have a story like Smash had.

First world is about the first time a girl raid some tombs. If you know what I mean.
