Summary
A cruise ship finds a barrel floating near their boat. The seamen pull it out from the water. However, a group of pirates, led by Alvida, board the cruise ship taking all the treasure in sight. A group of Alvida's pirates, including a choreboy named Koby, finds a barrel which they believe to contain rum. Much to their displeasure, inside the barrel is Monkey D. Luffy.

Expanded overview
"Fame. Wealth. Power. The man who had acquired everything in this world, the Pirate King, Gold Roger. The final words that were said at his execution, sent people to the seas. 'My wealth and treasures? If you want it, I'll let you have it. Look for it, I left it all at that place!' Men now, chasing their dreams, head towards the Grand Line. The world now enters a Great Age of Pirates!"

The series begins with a barrel floating in the water. Two sailors aboard a sort of cruise ship, currently holding a formal dance, of which Nami is involved, cast out a rope to reel the barrel in. When they do pull it in, however, another sailor spots a pirate ship in the distance, a pink one - belonging to Alvida. The pirate ship fires its cannons and the barrel is knocked out of the sailors' hands, sent rolling into the kitchen. Panic ensues as the pirate ship attacks the cruise vessel, and it rides up beside it as the pirates board the cruise ship, led by Alvida.

While pirates are attacking the ship, Coby, a young kid who is an essentially a slave of Alvida, sneaks into the kitchen and notices the barrel. As he is rolling it away, several pirates come in and ask why he's sneaking around. They then proclaim they are thirsty and just as one pirate is about to smash open the barrel with his fist, it burst open and so emerges Monkey D. Luffy, the hero of our story. The pirates think he is a barrel monster and flee, but Coby is intrigued by Luffy. Luffy and Coby head to the storage cellar of the ship and so starts eating apples out of a crate.

While in the cellar, Luffy asks if they are on a pirate ship. Coby replies that they are not, but rather on a cruise ship being attacked by pirates. Luffy then explains how his ship got destroyed in a whirlpool and so he barely survived. Coby then explains how he ended up getting picked up by Alvida's pirates and so has been their slave ever since. Luffy then mentions his dream, how he wants to become the Pirate King, and this causes Coby to lose it, realizing that Luffy indeed is a pirate. While this conversation is being held, Alvida's pirates tell their captain that there is a barrel monster aboard the ship, and they are all oblivious to the fact that Nami is robbing them blind.

Alvida bursts through the ceiling of the cellar and sees Luffy, mentioning how he actually isn't Roronoa Zoro. Luffy then asks who the fat lady is, enfuriating Alvida. Alvida attacks but Luffy picks up Coby and so launches up out of the cellar, out onto the deck. He is attacked by Alvida's pirates but knocks them all out using Gomu Gomu no Rocket. When everyone is shocked by this, Luffy explains that he is a rubber man. He says he wants to find One Piece and that he is currently looking for a crew, thinking that ten people is a good amount. Alvida demands Coby who the most beautiful woman in the world is, and Coby, inspired by Luffy, stands up for himself and yells that Alvida is a smelly, fat old hag.

Alvida becomes livid, and she attacks. Her mace strikes Luffy right on the head, but he stays standing. Luffy then winds back and uses Gomu Gomu no Pistol to send Alvida flying, defeated with one hit. Luffy orders Alvida's remaining pirates to get a boat ready for him and Coby, and they jump into the boat and sail away, briefly seeing Nami in her boat as they head off. Sailing out on the great blue sea, Luffy asks about the pirate hunter Coby mentioned. Coby says that he was captured by the Marines, and Luffy announces his intention of asking him to join his crew. This, of course, causes Coby to lose it again. Luffy makes up his mind, that he will recruit Roronoa Zoro as his next member. While they are speaking, at a nearby Marine base, there is a man with a green bandana tied to a cross, and he looks up...

Clip Edits

 * A few seconds of a sailor spotting something is cut out.
 * Coby noticing the huge barrel is taken out. This happens right before Nami infiltrates Alvida's ship.
 * Nami kicking one of Alvida's henchmen in the testicles was shortened to look like she just kicked him.
 * The scene where Coby is warning the henchmen that they'll get killed if Alvida finds out they wanted to drink some wine is cut out.
 * Some clips were switched as Luffy popped out of the barrel, and one second of one after he "punched" the pirate is cut out.
 * Luffy getting out of the barrel and the two pirates yelling at Luffy were cut out.
 * The clip showing Coby surprised to hear about Luffy's boat being sucked into a whirlpool is taken out.
 * The two pirates getting hit by Alvida's iron club is cut out.
 * There's a short clip added of Luffy and Coby zoomed out for about 3 seconds.
 * Luffy hitting Coby in the head because of his bout of hysteria is cut out. In the dub, Luffy says that he wasn't going to hit him.
 * Originally, Coby hysterically shook his head back and forth, saying anything Luffy wanted to do was simply impossible. Then he's punched in the head. In the dub, he shakes his head. But in the last 3 or so seconds, the frames are managed so that it looks like Coby is looking at Luffy while he was still saying "impossible" before he ducks.
 * The clips of Coby cowering before Alvida and Alvida emerging from the smoke are switched.
 * The silence between everyone after hearing what Luffy said is taken out.
 * Luffy punching one of Alvida's pirates is cut out.
 * Coby tells Luffy to run before Alvida really hurts him, but then he remembers what Luffy said earlier about deciding to become the next Pirate King, even if he dies fighting for it. The actual flashback of Luffy holding his hat is taken out, and Luffy's voice is just a voice in Coby's head.
 * The shot by shot scene of Luffy's Gomu Gomu no Pistol connecting with Alvida's cheek is cut out.

Dialogue Edits

 * Nami didn't originally have dialogue while Alvida's ship was attacking.
 * The henchmen say that the barrel is filled with water instead of wine.
 * Luffy originally didn't have dialogue that early into the scene where Luffy pops out of the barrel.
 * Luffy doesn't tell Coby that his boat got sucked into a whirlpool.
 * When Nami gathers up all the treasure she can get, she originally didn't have dialogue. Just the pirates above her did.
 * In the dub, Coby says that his dream was to be brave, which makes people think that he won't ever mention joining the Navy (Marines in the original), but he mentions joining the Navy later on.
 * Coby didn't ask why Luffy was drifting in a barrel in the original. Coby then asked if Luffy had a crew, but he said he had none. This is left out in the dub.
 * Coby explains to Luffy that the Pirate King is someone who has wealth, fame, and power, and that if Luffy wanted to be the Pirate King he must be looking for One Piece. In the dub, Luffy himself said that he's simply looking for One Piece.
 * An important line is taken out in the dub. Luffy says that he decided he wants to be the Pirate King, and he doesn't care if he dies fighting for it.
 * Coby originally didn't say that Luffy ate the Devil Fruit.
 * Luffy doesn't mention that he wanted 10 people in his crew in the dub.
 * Luffy saying that Zoro is a good guy is taken out.

Digital Edits

 * The dub makes it so that Luffy's mouth is closed when he pops out of the barrel.
 * The top part of the cross Zoro is tied to is erased as to avoid references to crucifixation.

Audio Edits

 * Right before the blades of the pirates are mysteriously cut, instead of the snapping sound of blades, it is a "bouncy" sound.
 * Luffy hits Coby again at the very end. The sound of it is taken out.

Name Changes
