The Reverse Mountain Arc also referred to as the Laboon Arc, is the seventh story arc of the anime and manga series, One Piece, and the first in the Alabasta Saga.

In this arc, the Straw Hat Pirates make their way to Reverse Mountain and begin the perilous task of scaling its tricky rapids in order to enter the Grand Line. As they descend the mountain, they find that something huge is blocking the entrance.



SummaryEdit

A Giant Whale and a Mysterious DuoEdit

As the Straw Hats sailed through a storm, Nami realized that they would be going up Reverse Mountain to access the Grand Line. The crew was incredulous at this, and Zoro wondered why they could not just go south. Suddenly, the storm stopped, and Nami revealed that they were in the Calm Belt. The Calm Belt was two strips of ocean surrounding the Grand Line, where there were no winds or currents. Nami urged the crew to row back to the storm, but the Sea Kings infesting the area then rose up. The Straw Hats struggled to get away, and once they had escaped, they turned their attention to successfully riding the dangerous current up Reverse Mountain. Their rudder broke, but Luffy shielded the Going Merry from hitting the mountain as the Straw Hats successfully sailed down into the Grand Line.[1]

Laboon's Introduction

Laboon blocking the Straw Hat Pirates' path.

When they came down, they immediately ran into a giant whale named Laboon who was blocking their path. The Merry ended up running into Laboon, which broke its masthead, and Luffy punched Laboon in the eye out of retribution for his seat being destroyed. Laboon then opened his mouth, causing the Merry to go in, although Luffy managed to escape. Luffy tried hitting Laboon to get his friends out, but before the whale dove underwater, he spotted and entered a trapdoor on its backside. Meanwhile, the other Straw Hats found themselves sailing toward an island inside Laboon. They encountered a giant squid,[2] which was taken down by a man named Crocus. After an initially tense confrontation, Crocus pointed them toward an escape route.[3]

Right then, Laboon began ramming himself into Reverse Mountain, causing further injuries to his head. As this happened, two mysterious people named Mr. 9 and Miss Wednesday prepared to go take out Crocus in order to hunt Laboon to feed their town. However, Luffy was sent tumbling through the corridors by Laboon's thrashing, and ended up crashing into Mr. 9 and Miss Wednesday, sending them flying into the area where the Straw Hats and Crocus were. Crocus went to sedate Laboon before confronting the two rogues, and he took two bazooka shots aimed at Laboon with his own body while Luffy defeated the rogues. They returned to Crocus' island, where Crocus explained about Mr. 9 and Miss Wednesday. He then revealed that Laboon had come to the Grand Line with a pirate crew, and stayed with him until the crew returned. Over 50 years had passed since then, but Laboon still believed that the crew would come back.[3] The Straw Hats exited Laboon's body, and threw Mr. 9 and Miss Wednesday into the water. The two agents swore revenge on the pirates before swimming away. At the Twin Cape, Crocus revealed that he had heard that the crew with Laboon had not died, but rather had left the Grand Line. He told this to Laboon, but the whale seemed to refuse to believe him and started ramming his head against Reverse Mountain, as though trying to get to the crew.[4]

Luffy Finds Log Pose

Luffy looks at the Log Pose he found.

Right then, Luffy took the Merry's mast and plunged it into one of Laboon's open wounds, causing the whale to lash out against him. The two traded blows, and Luffy proclaimed that he was now Laboon's rival, promising to see and fight him again once his crew sailed around the Grand Line.[4] This made Laboon happy, and Luffy painted his Jolly Roger on the whale's forehead, telling him not to bash his head against the mountain any longer. Meanwhile, Nami was shocked as her compass stopped working. Crocus revealed that to navigate the Grand Line, one would need a Log Pose to chart the differing magnetic fields of each island, all the way to the last island Raftel. Luffy had acquired a Log Pose that Mr. 9 and Miss Wednesday had left on the Merry, but it ended up breaking when he and Sanji got in a fight. However, Crocus agreed to give them a Log Pose out of gratitude for helping Laboon.[5]

Meanwhile, Mr. 9 and Miss Wednesday swam up to the Twin Cape to try to get their Log Pose back, as they needed to get back to their island and report to their boss before they got into trouble. However, the Unluckies then came to try and kill them. After recovering from the attack, the two rogues went to the Straw Hats and asked them to take them to Whisky Peak. They were unable to divulge their identities, but the Straw Hats reluctantly agreed to help. They then set sail for Whisky Peak, bidding farewell to Crocus and Laboon, and Crocus wondered if Luffy was the one he and Roger had been waiting for.[5]

Story ImpactEdit

  • The Straw Hats make it to the Grand Line.[1]
  • The Straw Hats meet a whale called Laboon, and Luffy agrees to reunite with him after making it across the Grand Line.[4]
    • Laboon is revealed to be waiting for a crew that left him 50 years ago. The Straw Hats will go on to meet one of that crew, who will join them to fulfill the promise his crew made.[3][4]
  • The Straw Hats agree to take two mysterious rogues to their home island of Whisky Peak. These rogues and their organization will drive the Straw Hats' actions through the rest of the Alabasta Saga.[5]
  • Information about the Grand Line and the Calm Belt is revealed.
    • The Calm Belt is a sea surrounding the Grand Line which has no winds and is infested with Sea Kings. It is very difficult, but not impossible, to traverse.[1]
    • The Log Pose is introduced, which helps sailors navigate the Grand Line due to its islands carrying their own distinct magnetic fields. The Straw Hats gain a Log Pose.[5]

Anime and Manga DifferencesEdit

Exiting LaboonEdit

The episodes concerning the arc were heavily edited, and much of the arc was completely omitted in the 4Kids dub.

Manga: When the Straw Hats manage to reach Laboon's "exit", they simply throw the Mr. 9 pair off the ship, who then wake up in the ocean.

Anime: The Mr. 9 pair manage to escape on their own, without the Straw Hats noticing them.

Warship Island ArcEdit

Manga: After the Straw Hat crew leaves Loguetown, they first reach the Calm Belt, and then head to Reverse Mountain, where they travel up the canal to enter the Grand Line.[6]

Anime: After the Straw Hat crew leaves Loguetown, they find a girl in the ocean and rescue her. They then head to Warship Island.[6]

Discussing Reverse MountainEdit

Manga: After the Straw Hat pirates leave Loguetown while passing the lighthouse, they begin to discuss how to enter the Grand Line. During the meeting, the ship drifts out of the storm into the Calm Belt. The weather is stormy and Nami wears her raincoat until after they get to the top of the mountain.[6]

Anime: The whole discussion is moved to the last episode, and there is no drifting into the Calm Belt due to having been shown in the second filler episode. It is not very stormy and Nami is not wearing her raincoat.[6]

Calm BeltEdit

Manga: Nami says it after they see a bunch of Sea Kings and the Going Merry is on a giant Sea King's nose.[7]

Anime: Nami explains the Calm Belt upon reaching it (after the rest of the Straw Hats show that they do not know about it).[7]

Calm Belt 2Edit

Manga: The Calm Belt does not take place during the Warship Island Arc and Apis is not with the pirates. Luffy saves Usopp when he gets tossed off the ship and is about to be eaten by a Sea King.[7]

Anime: The whole Calm Belt situation is moved to the third episode of the Warship Island arc, Apis is with them, and Luffy saves her from the Sea King instead of Usopp.[7]

Steel CuttingEdit

Manga: Zoro is not supposed to be able to cut steel until the Alabasta arc.[8]

Anime: Zoro cuts the steel chain from the Marine ships. He even says "There is nothing I cannot cut". This becomes one of the major plot holes in the anime series.

Note: After Luffy is declared wanted, Zoro is the one who cuts the cannonball in two fired at them by Fullbody.[8]

Hello EricEdit

Manga: The Straw Hat Pirates go up Reverse Mountain without anyone interrupting them.[8]

Anime: As the Straw Hat Pirates go up Reverse Mountain, Eric lands on the Going Merry, yet he is later tripped by Nami and falls off the ship into the sea.[8]

Translation and Dub IssuesEdit

4Kids has cut and changed much of the arc for unknown reasons, but it may be due to Laboon's scars and Luffy stabbing the Merry's mast into his head. The Straw Hats entering the Grand Line and receiving the Log Pose is rewritten as a result, and shots from other segments of the anime are rearranged to fit the script:

  • Rather than confronting Laboon, the Straw Hats instead encounter an iceberg in their way, which Luffy destroys with the ship's cannon. In the Japanese version, he fires it to slow the Going Merry down and keep it from crashing into Laboon. The removal of Laboon eventually creates a plot hole in the Thriller Bark Arc.
  • The Log Pose suddenly appears onboard the ship, and the explanation of how it works and the physics of the Grand Line are told through flashbacks by the crew when they were children instead of by Crocus, whom they never meet in the 4Kids dub. Yet until the Sabaody Archipelago Arc, we end up learning more about Crocus which creates more problems.
  • Without Crocus, the Straw Hat Pirates never knew anything about Raftel and how this would come to play in the Zou Arc when he gets brought when discussing the island with Zou's rulers
  • The Straw Hats arrive at Whisky Peak (renamed Misty Peak) on their own rather than being led there by the Mr. 9 pair.

Because of these changes, many fans have expressed outrage and disapproval at 4Kids for creating something that was obviously not part of the author's original canonical storyline, as well as how the American dub will fit Brook into the plot.

However, with the 4Kids dub cancelled and FUNimation now dubbing the series, the Reverse Mountain Arc saw its first English anime release on June 30, 2009 as part of FUNimation's uncut "One Piece Season 2 First Voyage" release.
