Yu-Gi-Oh! 5D's

Yu-Gi-Oh! 5D's (遊☆戯☆王5D's（ファイブディーズ）) is the second main spin-off of the Yu-Gi-Oh! franchise. The series aired in Japan between April 2, 2008 and March 30, 2011, following the conclusion of the previous series, Yu-Gi-Oh! GX.

The story focuses around characters playing a card game called Duel Monsters. This series introduces Synchro Monsters to the Yu-Gi-Oh! Trading Card Game. A new method of dueling exists where motorcycle-like vehicles called D-Wheels (Duel Runners in the English version) are used, and the duelists engage in games called Riding Duels (Turbo Duels in the English version). The show is set in the distant future, where the upper class population live in Neo Domino City (New Domino City in the English version) and the lower class in a remote island where Domino's sewage is transported, Satellite. Yusei Fudo, the 18-year-old protagonist, lives in Satellite and makes it his objective to reach his rival Jack Atlas, who lives in Neo Domino. The series focuses on the five Signers, people embodied with a mark of one of the legendary Five Dragons who serve an ancient deity called the Crimson Dragon, their conflict with the Dark Signers, and the Three Emperors of Iliaster.

As with the previous two anime series (Yu-Gi-Oh! Duel Monsters and Yu-Gi-Oh! GX), ''Yu-Gi-Oh! 5D's'' was acquired by 4Kids Entertainment for broadcasting in the United States in September 2008. The series aired on The CW4Kids, from September 13, 2008 to September 10, 2011, though several episodes were left unaired. The English-language version premiered on July 24 at San Diego Comic-Con 2008, where the first English-dubbed episode was previewed. Like the previous two English dubs, changes have been made to the plot, cards, and character names. On June 1, 2009, the series began airing 5 days a week on Cartoon Network. A manga based on the show began serialization in V Jump monthly Magazine from August 2009 to January 2015.

5D's was eventually succeeded by Yu-Gi-Oh! Zexal, which premiered on April 11, 2011.

Plot
''Yu-Gi-Oh! 5D's'' is set in the future in Neo Domino City. Seventeen years prior, a reactor called Moment within the city malfunctioned and caused a great earthquake that split the city in two parts: Satellite, the rundown and poverty-stricken part, and Neo Domino City, the wealthier and urban part, with access from Satellite to Neo Domino being strictly forbidden. Yusei Fudo, an aspiring duelist from Satellite, builds his own D-Wheel, but his best friend Jack Atlas betrays him and steals his vehicle along with his most precious monster, Stardust Dragon, escaping to Neo Domino. Two years later, Yusei builds another one and secretly travels to the city to win back his Dragon. Jack has made a name for himself and his monster, Red Daemon's Dragon, as the current Riding Duel King in Neo Domino City. Yusei and Jack face each other in a Riding Duel, and Yusei is able to regain control of Stardust Dragon. As Stardust and Red Daemon's Dragon battle, Yusei and Jack's arms glow red, a third red dragon appears, and brings an abrupt end to the fight. This attracts the attention of Rex Goodwin, the head of the Public Security Maintenance Bureau, who reveals to Jack a five thousand year old secret, involving the "People of the Stars" (星の民), a pre-Incan civilization, the "Crimson Dragon" (赤き竜), and "Signers" (シグナー), identified by a red birthmark on their arm that represents a part of the dragon. Goodwin also reveals that Jack and Yusei, along with child Duelist Luca and Psychic Duelist Aki are descendants of them and are destined to face the Dark Signers, duelists resurrected from the dead to serve the evil Earthbound Gods. The Signers head to Satellite to face these foes who consist of: Rutger Goodwin (Rex's brother, a former Signer with the dragon's Head mark and leader of the Dark Signers), Kyosuke Kiryu (a former friend of Yusei, Jack and their friend Crow Hogan), Demak (the one who stole the Ancient Fairy Dragon card until Luca, with her twin brother Lua's help, wins it from him), Misty Lola (a model who blamed Aki for the death of her brother Toby, until she discovers Divine, Aki's former friend and leader of a psychic duelist organization, was the true culprit), Bommer (who blamed Rex Goodwin for his village's disappearance until he discovers the Dark Signers were responsible), and briefly Carly (a blogger with feelings for Jack). After their defeat, Rex Goodwin is revealed to have become a Dark Signer and uses his brother's severed arm to become a Signer as well. Yusei, Jack and Crow then face him in a Riding Duel in order to stop him and the released King of the Netherworld from finishing off the Signers and destroying the world. Before the final attack, Yusei gains the Head mark while Crow gains his former Tail mark, making him a Signer. With the power of the Crimson Dragon and Yusei's Saver Star Dragon, he defeats Goodwin who, along with Rutger, sacrifice themselves to destroy the King of the Netherworld and revive the Dark Signers as normal people again.

After the Dark Signers' defeat, Neo Domino City and Satellite are finally reunited into one prosperous city with the building of the "Daedalus Bridge", an intricate net of roads linking both Satellite and Neo Domino City with some sections also used for Riding Duels. Yusei and his friends, now calling themselves "Team 5D's", prepare for the upcoming World Riding Duel Grand Prix (WRGP) tournament. A new threat appears, the Three Emperors of Iliaster, whose main monsters, the "Machine Emperors", can absorb Synchro Monsters from their opponents to empower themselves. Yusei encounters a fellow competitor, Sherry LeBlanc, who is investigating the Iliaster organization, that is reportedly responsible for her parents' deaths. Team 5D's is also joined by a mysterious amnesiac mechanic named Bruno, whose secret alter ego Antinomy teaches Yusei about the secrets of "Accel Synchro", a summoning method that allows him to bring out an improved version of his Stardust Dragon. The WRGP soon begins, with Team 5D's facing tough opponents before eventually confronting the Emperors themselves, who are revealed to be three different incarnations of Aporia, a cyborg sent from the future to destroy Neo Domino City to prevent a great calamity from befalling mankind in the future.

Although Team 5D's defeats Aporia and wins the WRGP, a massive citadel known as the Ark Cradle appears and threatens to crash into Neo Domino City and destroy it. Team 5D's climbs aboard it to stop it. Before reaching the core of the fortress, they confront three individuals guarding its access: Aki and Crow face Sherry, who was promised to have her parents returned to her; Yusei faces Bruno, who recovered his memories of being Antinomy, another member of Iliaster; and Jack, Lua and Luca face Aporia. Lua dies during the duel and is revived by the Crimson Dragon, becoming the sixth Signer bearing the mark of the dragon's Heart. When the Signers finally reach Z-one, Iliaster's leader, Yusei borrows his friends' dragons to add them to his deck, and challenges Z-one to a final Riding Duel to decide Neo Domino City's future. Z-one is revealed to be a scientist from the future who assumed Yusei's identity and traveled back in time to prevent the destruction of humanity. Yusei manages to use his friends' cards to perform a "Limit Over Accel Synchro" and summon his strongest monster, "Shooting Quasar Dragon". After Z-one is defeated by Yusei, he decides to entrust the future of mankind to Yusei, and sacrifices himself to destroy the Ark Cradle and save Neo Domino City from destruction.

A few months pass after the Signers' victory over Iliaster, and the former members of Team 5D's move on with their lives following separate paths. They all part ways, except for Yusei, who decides to stay in Neo Domino City and research for a way to stop the destruction of humanity in the future. The other Signers decide that they will return after fulfilling their dreams. As they ride together one last time, the Crimson Dragon removes their Signer marks, as their mission as Signers is accomplished.

Themes
The first story arc addresses themes such as social class division, segregation, and discrimination, depicted through the interactions between residents of Neo Domino City, and Satellite. The Dark Signer arc deals with the relationship between past and present, as the heroes (especially Yusei, Aki, and Jack) must come to terms with the questionable actions they, or their family members, have made. The final two arcs, the World Grand Prix and Ark Cradle, build on the previous arc by exploring the connection between present and future, as Time Travel plays a major role in how the story unfolds. Synchro Monsters also play a major role in the final two arcs, as their subsequent overuse in the future prompts the final antagonists to seek the destruction of Neo Domino City. Lastly, just like all Yu-Gi-Oh! series, 5D's places a huge emphasis on bonds and friendships.

The most prevalant motif of this series is Speed, which naturally fits with its gameplay gimmick; Riding Duels (Turbo Duel in the English Dub). At the start of a Riding Duel both players must activate Speed World; A Field Spell card that requires the use of Speed Counters to activate Speed Spells (the latter replacing traditional Spell Cards in Riding Duels) One Speed Counter is allocated to each player at the beginning of every turn. A miniature race, with a mutually a agreed upon goal point, is used at the beginning of a Riding Duel to determine who gains the first turn.

Similar to how the original series utilized elements of Egyptian mythology  to drive the plot, 5D’s loosely used bits of  Incan Mythology (such as the Nazca Lines) early on to set the groundwork for its supernatural phenomena and lore. To push this motif even further, the manga (which featured an entirely different plot from the anime) depicted the origin of Riding Duels being played on horseback, in coliseums, by Ancient Incan civilizations.

Anime
''Yu-Gi-Oh! 5D's aired on TV Tokyo between April 2, 2008 and March 30, 2011, following the end of the previous series, Yu-Gi-Oh! Duel Monsters GX''. As with the previous two series (Yu-Gi-Oh! Duel Monsters and Yu-Gi-Oh! Duel Monsters GX), this series was acquired by 4Kids Entertainment for broadcasting and began airing in the United States in September 2008. The English adaptation of ''Yu-Gi-Oh! 5D’s'' is also distributed by Warner Bros. Family Entertainment and Warner Bros. Television Animation. Yu-Gi-Oh! 5D's began airing on The CW4Kids, starting on September 13, 2008, and later aired on Cartoon Network. On May 29, 2010, the series once again began airing in 1-hour episode blocks on the CW4Kids. The series moved over to the Toonzai block on September 18, 2010. The last episode of the dubbed series aired on September 10, 2011, leaving out several episodes from the Japanese broadcast. As a result, 5D's became the second series to not have a complete English dub. Changes have been made to the plot and cards, character names have been localized, and violent scenes have been edited.

In Germany, however, the dub stopped using the 4Kids version and began adapting the show directly from Japan from episode 65 onward for unknown reasons. While the original voice cast from the first 64 episodes was still used, the show no longer edited quite as much, used the original music (including the original Japanese opening and ending themes), and adapted their scripts directly from the original Japanese scripts rather than from the revised English scripts.

On September 22, 2010, Toonzaki and Hulu uploaded subtitled and dubbed episodes of ''Yu-Gi-Oh! 5D's''. These episodes use the English names for the cards instead of the Japanese names. In an Anime News Network interview with Mark Kirk, Senior Vice President of Digital Media for 4Kids Entertainment, Kirk claimed this was due to legal reasons.

On April 2, 2018, the series was released with Latin American Spanish dubbing in the United States (for US Hispanic audiences) on ¡Sorpresa!. Subsequently, the series was uploaded on the streaming service VEMOX, also in Spanish.

Manga
A manga series based on the show written by Sato Masashi began serialization in V Jump from August 21, 2009 to January 21, 2015. Like the manga adaptation of Yu-Gi-Oh! GX, the adaptation features an original storyline, different monsters, and various differences from the anime version. The series has been licensed by Viz Media for North America.

Trading Card Game
''Yu-Gi-Oh! 5D's added a new gameplay element to the Yu-Gi-Oh!'' Trading Card Game by introducing Synchro Summoning to the game. To Synchro Summon the new white-colored Synchro Monsters, a Tuner Monster and a non-Tuner monster is required to be on the field, and their added levels must equal to the desired Synchro Monster to be summoned. A new monster type known as Psychic was also added to the game.
