One Piece (English, 4Kids Entertainment)

Broadcast
On June 4, 2004, 4Kids announced they had acquired the television distribution and merchandising license for One Piece  in the Australia, Canada, Ireland, New Zealand, South Africa, United Kingdom and the United States.

The One Piece anime debuted in America on the FoxBox TV block (later known as 4Kids TV) on September 18, 2004. Cartoon Network announced their aqusation of the series on February 16, 2005. In the UK, Toonami announced that they had acquired the series on November 18, 2004 and began their broadcast on April 23, 2005.

In an interview on April 24, 2005 4Kids CEO Al Kahn suggested that One Piece, along with every other 4Kids property, would receive an uncut DVD release, and added that anime fans would "have to accept the fact that it's going to be available in two styles". The American home video rights to the series were sub-licensed to VIZ Media, who began releasing the edited version of the series on DVD in February 2006 with "English TV Version" specified on the DVD covers. Despite Kahn's earlier statements, Viz were unable to release an uncut version as they were not involved with the dub's production.

On November 11, 2005 One Piece (along with Mew Mew Power, another series licensed by 4Kids) was reported missing from the 4Kids line-up. However, on January 2, 2006, the series was announced to be continuing on February 11.

On March 16, 2006, 4Kids announced plans to concentrate only on their fully-owned properties. A fall of profit was blamed on the shortfall of several of their dubbed licenses such as Pokémon and Yu-Gi-Oh, although One Piece and several other licenses they held were said to offset the results. The company as a result later dropped a few shows including one of their biggest earners, Pokémon. The dubbing of new anime lessened, and 4Kids announced on December 6, 2006 that they had canceled production of their One Piece dub and dropped the license. Ultimately, 4kids produced 104 English-dubbed episodes from the first 143 Japanese episodes.

Censorship & edits

 * The opening and ending for the dub was "One Piece Rap", though an English cover of "We Are!" was used in early promotional material. The original Japanese ending credits song (and even as well as the next episodes previews) were replaced with an altered version of the "One Piece Rap" with scrolling credits followed by the 4Kids Entertainment logo.
 * As per 4Kids standards, any music were replaced with alternative soundtrack composed by John Angier, Louis Cortelezzi, Matt McGuire, Ralph Shuckett and Dan Stein, which also reused from other shows 4Kids has dubbed.
 * Every major or minor character who is considered a pirate had their dialect changed in some way to mimic the pirate accent stereotype that is present in the west and will often use pirate lingo throughout the dub.
 * The commercial break eyecatchers were cut and replaced with fade-ins, and an extra ad break were added for American audiences.
 * Any alcohol reference were edited or replaced, with the drink being recolored to have it looks like juices.
 * Guns has been changed to look more like water guns.
 * Cigarettes has been edited out in the dub, which one of the infamous major edits is having Sanji's cigarettes redrawn into an red lollipop (similar to the Korean dub), and as well as changing Smoker's name to "Chaser" while keeping smokes which came out from his mouth.

I’m Gonna Be King of the Pirates! (Episode 1)

 * The scene where Nami kicking an pirate is shortened so it's looks less obvious.
 * An bounce sound effect was added in an scene where Luffy breaks two swords offscreen.
 * The scene where Alvida punishes her subordinates were censored to edit out scenes:
 * The part where Alvida's mace hits one of her subordinates was cut out, skipping straight to him flying.
 * The part where the mace fall back down hitting the other two pirates on the head was cut out.
 * The scene where Koby tries to pleads Luffy not to hit him (in fact he does) were edited to remove the part where Luffy's punch hits Kobe's head.
 * The part where Luffy punches an pirate in the face were cut out.

Roronoa Zolo: Pirate Hunter (Episode 2)

 * At the beginning of the episode, when Koby talks about Zoro, the part where an shadow person falls down after Zoro cuts the screen were edited out.
 * The cross where Zoro's tied up were edited to remove the top, likely due to religious references. The similar edits also can be seen on 4Kids dub of Yu-Gi-Oh! anime.
 * The onigiri (rice balls) the girl gives to Zoro were edited to cookies.
 * The close-up scene of the notice Helmeppo holding were cut out, likely due to saving time.
 * In the flashback scene where were shown the reason Zoro was tied up, the part where Zoro punching Helmeppo in the face was cut out. The bruise in Helmeppo's face were also edited out, and the sword pointing at Helmeppo were redrawn to be further away from Helmeppo's neck.
 * The panning scene of Nami were shortened.
 * Captain Morgan's cigar has been edited out.
 * Although the scene was left in, the scene where Captain Morgan attacking the soldier which refusing to obey an order were edited to remove the sound effect of the axe. This was probably done to lessen the overall impact of the hit.

An Unlikely Pair: The Pirate & The Pirate Hunter (Episode 3)

 * One of the most infamous edits is where Helmeppo's pistol which pointed at Koby, were replaced with an cartoony spring hammer, with the only remaining part of the pistol is the grip.
 * The small fragments of Morgan's shirt cut from Zoro's sword were removed.
 * The map of the Grand Line were redrawn to remove almost any of the English texts, but consequently the animated arrow that's shown to indicate the Red Line is removed.
 * Towards the end of the episode, as Luffy and co are about to leave the island, Luffy purposely antagonizes Koby by threatening to reveal that he is a part of Alvida's crew in order to get Koby to stand up for himself, the part where he punches Luffy in the face with Luffy returning the favor were edited to remove Luffy's punches, although Koby's punch were left in.

The Passing Of The Hat (Episode 4)

 * The wine bottle that is next to Shanks in an scene were edited out, but the very same wine bottle was kept intact later where Shanks offers it to the mountain bandit, but the color of the bottle were changed from purple to orange.
 * During the confrontation between the Red Hair Pirates and the Mountain Bandits, the guns from both parties have been altered to look more like cork guns and are stated in dialogues as such.
 * Despite the rifle the Shanks crew member used to beating the Bandit was left unedited, the part of an scene where he pointing the gun at the mountain bandit's leader were edited to remove the rifle and his arm.

Translations

 * Most of the English texts were removed in this dub.
 * The dub renames the Devil Fruits as a whole to "Cursèd Fruits" (pronounced as two distinct syllables) to avoid the reference to the devil, which some religious viewers may have found offensive.
 * The names of attacks were changed for example, Luffy's "Gum Gum Pistol" were changed to "Gum Gum Blast".
 * The Kaigun military force have their logos branded with the word Marine written in English and changed all texts relating to the Kaigun to Navy (probably to avoid confusion), despite the fact that "Kaigun" actually translates into English as the "Navy".
 * Roronoa Zoro's name have the latter changed to "Zolo" to prevent confusion with an fictional character named Zorro and legal issues. The name also (still) applies to the English manga (as of currently) and as well as the old edited-for-TV FUNimation dub of the anime, though with a few rare exceptions.
 * That name was referenced in the FUNimation English dub of Skypiea arc at one point by Usopp. "We've got zero and I mean Zoro, no I mean Zolo chances, no no zero, I wonder how Zoro's doing?"
 * The "ANCHOR" text in young Luffy's clothes were removed in episode 4, despite the text being in English.
