Seasons & episodes

Yusei manages to survive Andre's onslaught, but still takes a lot of damage to his life points, especially when Andre brings out his Synchro Monster. Yusei summons out Stardust Dragon and destroys his monster, but before Yusei can win using Speed World 2's effects, Team Unicorn's practice time ends, along with the duel. The next day, Sherry briefly visits Yusei to ask about the thing they both saw, and Martha's kids give Crow a banner they made. This inspires him to train, but he suddenly crashes and breaks his arm, leaving him unable to participate, so Akiza offers to take his place. Crow, whilst initially furious at the decision, offers to coach Akiza in her training.

The WRGP Preliminaries begin with Team 5D's facing against Team Unicorn. Jack goes up first in the hopes of putting his Power Deck against Andre, who uses an overboost system to turn the corner first, and take the first turn. Jack summons out Red Dragon Archfiend, but takes a lot of damage thanks to Andre's strategy. Andre than summons out Thunder Unicorn, which puts Jack in a tighter spot. Bruno notices a problem in Jack's Duel Runner, but Jack refuses to take a pit stop, and manages to destroy Thunder Unicorn. Yusei realizes that they had been tricked by Team Unicorn into using a Power Deck, but it is too late, as Andre defeats Jack using Speed World 2's effects, the force of which causes his Duel Runner to crash.

Despite his injuries, Jack gets up to push his Duel Runner to the end of the lap to pass the baton over to Akiza, managing to do so before they are knocked out. Akiza immediately summons out Phoenixian Cluster Amaryllis to deal some damage to Andre. However during the next turn, Andre manages to remove it and bring back his Thunder Unicorn. The next turn, Akiza summons out Black Rose Dragon and, to everyone's surprise, Stardust Dragon, which Yusei had given her. However, Andre ends the battle phase before Stardust can attack and uses Thunder Unicorn to beat it. Before Andre can use Speed World 2's effect, Akiza wipes out her own life points to revive Stardust Dragon, in order to pass it on to Yusei. As Yusei continues the fight, Akiza laments that she couldn't help much, but finds encouragement from her parents and the crowd.

Yusei manages to destroy Andre's key Speed Spell card, but in doing so allows Andre to activate that, despite knocking himself out, takes a huge chunk out of Yusei's life points. Yusei then faces Team Unicorn's next duelist, Breo, who soon summons his Synchro monster, Voltic Bicorn. He soon destroys it however in order to implement his deck destruction tactic.

Breo manages to destroy Stardust Dragon and leave Yusei with just five cards left. Yusei soon summons Junk Destroyer and knocks Breo out, leaving him just 1000 life points and four cards to face against Team Unicorn's final member and leader, Jean. Jean summons out Lightning Tricorn, but Yusei manages to avoid losing to Speed World 2's effects. However, Jean soon destroys Yusei's monsters and launches a direct attack at him.

Yusei survives Jean's attack and summons Stardust Dragon. He has trouble going up against Jean's strategy, but then Jack stumbles from his bed to give Yusei and the team morale. Yusei Fusion Summons Dragon Knight Draco-Equiste, a move Jean wasn't expecting, and the two continue to fight through the last of Yusei's deck. Jean manages to survive the strategy laid out by Yusei, and is in a position where he can just end the turn to win due to Yusei's deck not having any cards. However, the duel has given him a desire to fight, and after encouragement from Andre and Breo, Jean launches an attack, which ultimately backfires against him, after Yusei increases the defense points of Rapid Warrior, causing Jean to lose all of his life points, and ultimately, the duel.

Jean give thanks to Yusei for the "fun duel," and the two teams promise to reach the WRGP finals together. As Team 5D's celebrates their victory in their garage, they are visited by Sherry, who had beaten three duelists by herself in her round. They discuss things about Yliaster, and how recent events have been related to them. Sherry reveals they are being targeted by Yliaster, due to them being Signers (not including Sherry). She also talks about the strange experience that she, Yusei, and Bruno had experienced back at Sector Security. After Sherry leaves, Bruno feels weird, and goes to the beach where he washed up upon. Upon finding a cat, it triggers his memory, and his eyes glow red again. The next day, as Yusei and Crow go to watch Team Unicorn's battle against Team Catastrophe, they arrive to find Team Unicorn's Duel Runners crashed, and Andre and Jean hospitalized.

Team 5D's prepare to face up against Team Catastrophe, the leader of which, Nicholas, has been given a Card of Darkness by Primo. Team 5D's are later visited by Breo, and study the memory chips of Jean and Andre's Duel Runners, revealing something had caused their wheels to suddenly lock up and crash, the same reason why Crow crashed. After studying a video Carly gave them, the Signers believe it to be linked to a monster called Hidden Knight Hook. Akiza gets hit by the same phenomenon, and her psychic powers fail, as she loses it, to save her from getting injured. (And, Akiza's psychic powers don't return until Episode 140, after the Ark Cradle appears.) Despite his arm not being fully healed, Crow decides to take her place in their match against Team Catastrophe. The first round sees Crow against Hermann, who instantly summons Hidden Knight Hook. As it uses its effect against Crow's attack, Crow notices a strange hook aim for his wheel and barely manages to avoid it.

Crow continues to bear the pain of his arm, whilst he avoids Hidden Knight Hook's assaults on his Duel Runner. He eventually manages to destroy it, and knock Hermann out by summoning out his Black-Winged Dragon, but when Hermann tries to revive his Hidden Knight Hook, Crow sacrifices his dragon in order to completely destroy Hidden Knight Hook before it can attack him, and then defeats Hermann. His arm at the peak of his pain, Crow passes the duel on to Jack, who begins the next round against Nicholas. Nicholas uses another Card of Darkness, a trap intended to knock both of them out, however it hurts both of them, as Primo has no more use for Nicholas, and allowed his protection against the Card of Darkness to expire. Jack escapes defeat, thanks to his monster's special ability, and rescues Nicholas before he crashes. With Nicholas' Duel Runner destroyed, Team 5D's automatically qualifies for the quarterfinals.

Sherry tries to get the Card of Darkness off of Nicholas, but its card face disappears as soon as she touches it. Meanwhile, the Ghosts start attacking other duelists, overwhelming them with Battle Royale Mode, which makes the battle damage of a duel real. Yusei, Jack, Sherry, Elsworth and Kaz go to help what duelists they can. Aggravated and tired of constantly having his own plans thwarted, Primo orders the Ghosts to gang up on Yusei, who is joined by Sherry and Elsworth. Although they gain the upper hand with their Synchro Monsters, they are soon overwhelmed by the enormous number of Ghosts, and Sherry and Elsworth are taken out, leaving only Yusei to stop them.

Noticing Yusei is in trouble, Bruno, having regained his memories, remembers his mission to protect Yusei and to stop the Yliaster trio at all costs, after being reminded by Z-ONE, transforms into Vizor, calls over his duel runner, and helps Yusei evade the Ghosts. Primo becomes agitated and joins the duel himself. Bruno teaches Yusei about Accel Synchro, about how Ener-D powers through people's hearts and the Clear Mind that can control it. Taking these things into account, Yusei accelerates to top speed and is able to see a new monster. Bruno, who had lost his memory after previously battling Primo, stays behind to duel him again. Meanwhile, Yusei arrives at a crater, where another stone tablet has landed. Upon touching it, he is transported to the white room he had went to before, and receives an Accel Synchro card.

After Yusei and Bruno mutter about this transformation being Primo's true form, Primo demonstrates to Yusei one of his new abilities. He causes his Machine Emperor to create a field of energy, which causes glass everywhere in New Domino City to shatter, and results in blackouts. Remembering the destruction caused by the original Ener-D reactor spun in reverse, Yusei screams, "Stop," and rams Primo's duel runner. Startled, he loses concentration and the destruction stops. Frustrated, he calls Yusei "inferior." When Yusei demands Primo to ressume the duel, Primo rides up besides Yusei, and then activates his own battle Royale Mode. Yusei begins his duel with Primo by summoning out Junk Destroyer and manages to deal some damage. Primo becomes furious, and gets his Machine Emperor Wisel to create another field of energy, which results in lightning bolts striking everywhere in New Domino City, causing electrical devices to fail.

With Stardust Dragon absorbed by Machine Emperor Wisel Infinity, Yusei becomes frustrated over why his attempt at performing an Accel Synchro didn't work. Barely managing to survive Primo's attacks, Yusei eventually manages to retrieve Stardust Dragon. Primo uses his Machine Emperor to start a tornado to affect the city, also putting a child named Haruka in danger, but Akiza manages to save her without using her psychic powers. Then, Primo has Wisel create another field of energy, this one to torture Yusei, panting, and in pain, the marks of the other Signers reflect the pain that Yusei is feeling. Regaining his determination and clearing his mind, Yusei finally manages to perform an Accel Synchro, and summons Shooting Star Dragon, which flies into the tornado, and disperses it, and then flies up into the sky to shine its light on New Domino City.

Noticing the light caused by Shooting Star Dragon, Jack and Crow decide to heads towards Yusei. Yusei uses Shooting Star Dragon's special ability, which allows him to once-per turn, draw the top 5 cards of his deck, and Shooting Star Dragon can attack the number of times equal to the number of tuner monster cards drawn. Yusei then takes the marks of the Signers, which allows him to draw 5 tuner monster cards, one per mark (including his own). Yusei then gains the Seal of the Crimson Dragon, with the result of Yusei's lucky draws shocking Primo. When Yusei attacks, Primo manages to block the first 2 attacks by sacrificing Wisel Guard, but the remaining 3 attacks causes him to lose. Primo is unable to believe it, and questions if he was being done in by a human. Then, the rest of Machine Emperor Wisel collapse onto Primo and explode, causing Primo to scream as he loses the rest of his life points.

Greiger has a vision of Jack being destroyed by his own power, so calls both him and Yusei over to the Nazca plains. He talks about how he had built a temple to help seal off the Earthbound Immortals, but lately has been troubled by the appearance of what's known as the Crimson Devil. Greiger warns Jack that using his general power tactics will destroy him, but Jack insists he can only fight using power. Greiger suggests a turbo duel, but Jack is surprised to find his opponent is his little brother, Max, who appears to be possessed by something. Jack summons out Red Dragon Archfiend but finds himself having trouble against Max's special deck. When Jack attacks, he finds himself attacked by his own power just like Greiger's dream, and the duel is called off. Jack becomes defiant about abandoning his power tactic and drives off.

Jack arrives at an abandoned village where he encounters a strange Familiar who reveals himself to be the Crimson Devil's servant, who offers him a chance to gain great power. Meanwhile, Greiger comes to a conclusion that the actions of him and Max were those of the Crimson Devil. Jack, seemingly in a trance, goes into a temple that Greiger had built, leading him to where the Familiar challenges him to a duel. Yusei and company try to follow but are stopped from interfering by the Familiar, who reveals that if Jack loses, his body will become a host to the Crimson Devil, and cuts them off from Jack by creating a very narrow platform, and seals off the only exit. The Familiar announces that he, Greiger, and Max will all become sacrifices to the Crimson Devil. Jack struggles against the Familiar's Yomi deck, which punishes power play.

Jack summons out Red Dragon Archfiend, but is still hampered by the Familiar's Yomi deck, though eventually manages to deal some damage. The familiar tries to use the Crimson Devil's power to knock Jack off his platform, but he hangs in there. Greiger is reminded of a legendary Signer called Burning Soul who once defeated Scar Red Nova alongside the Crimson Dragon, believing Jack to be his descendant. Jack starts to play more strategically and deals more damage to the Familiar. The Familiar becomes angry and summons a powerful monster, bringing the release of Scar Red Nova closer. Just then, Jack produces a Burning Soul and, with the help of the Crimson Dragon, also known as Quetzalcoatl, seals the Crimson Devil forever into the card of Scar-Red Nova Dragon, and performs a 'Double Tuning' to summon that monster and defeat the Familiar, who was later killed by a collapsing wall during the destruction of the temple, due to the power of Scar-Red Nova Dragon's "Burning Soul" attack.

Yusei and the others catch Lazar in disguise stealing some instant noodles. Wanting to find out more about Yliaster, they corner him, but he manages to escape. Hoping to lure him out, the gang hold a fake noodle product launch where people duel Crow in a mascot outfit for a chance to win some noodles. Lazar eventually shows up in another disguise, and whilst they fail to trap him, they manage to put a tracer on him and track him down. Crow challenges him to a duel to get information about Yliaster out of him. Lazar brings out his Jester Lord and seals Crow's tuner monster abilities, but Crow manages to make a comeback and destroy it. As Lazar's family show up to spectate, Lazar makes a comeback with his Jester Queen. Crow holds back his attack out of consideration for Lazar's family, leaving him with the choice of how to end it. Lazar decides to lose and tell the others about Yliaster.

The (Signers) gang, along with Sherry, interrogate Lazar about Yliaster. After some mistarts, involving him just talking about his family and love of cup ramen, Lazar eventually leads them to an arcade game where a puzzle duel is required to be cleared in order to access a hidden database. With three chances, Lazar fails the first time as he does not deal enough damage to win. Akiza uses her knowledge of Turbo Duels to win instead. However, Jack makes a miscalculation in the second round and loses the second credit, leaving Yusei to clear the round himself. With the game cleared, Lazar accesses the data, which reveals the company who sent the three Yliaster members to the Public Information Security Bureau, The Ener-D Express Development Agency.

Yusei, Sherry and Bruno infiltrate the Ener-D Express Headquarters, disguised as representatives of Bolger's company. There, they are shown a new Infinity shaped Ener-D reactor by Clark Smith, which is supposedly designed to allow Turbo duelists to travel through wormholes. Wanting to learn more, they sneak into Clark's office to obtain an access key for Level 10 clearance. When Clark returns, Yusei holds him off by challenging him to a duel with some new rules Clark throws in whilst Sherry and Bruno head for the restricted area. Clark's duel requires players to declare the type of card they want and successfully pick the right one in order to use it. However, Clark gains an advantage by cheating using his glasses. Realizing this, Yusei manages to summon Stardust Dragon and defeats him. However, Clark had already figured out their identities and sets off the alarm.

Clark reveals that he killed Sherry's parents for discovering the secret behind Infinity, which was being used by Yliaster to change history. He sends Yusei, Sherry and Bruno into a wormhole, in which they are doomed to break up and crash. Sherry uses her card to regain control of the shuttle, but ends up getting sucked out. Yusei and Bruno enter a "warped" dimension in the future, and pass by a strange island (a gigantic, floating, upside-down "metallic fortress", the Ark Cradle), where Yusei is briefly visited again by his father, who warns him of an Ener-D that will destroy mankind, before returning him and Bruno to their homeworld (the Present). Unhappy with Clark's actions, Yliaster erases Clark from existence, which spreads a blast of white light across New Domino City. Another WRGP team, Team Ragnarok, also notices the blast, but were protected by their Nordic God cards. Yusei and Bruno regroup with the other Signers, who were defended from the blast by their Signer marks.

After reading up on Team Ragnarok, Leo runs into another WRGP team, Team Taiyo, and injures his knee. After taking Leo to fix up his knee, they tell him about their precious Duel Runner, which got banged up in the Ghost incident, though one of the members, Jinbei, shows disdain for offers of help. Leo gets Yusei and Bruno to help them fix it, and despite Jinbei's objections, the others allow them to help. Meanwhile, Jack, Crow and Akiza attend an exhibition duel featuring Team Ragnarok, with one of their members, Dragan, challenging Jack to a duel. Jack summons out Red Dragon Archfiend, whilst Dragan brings out his Aesir, Thor. As Thor attacks, the powers of both monsters starts to resonate, and causes a quake, forcing Lazar to end the duel before damage can be done. After Yusei finishes fixing Team Taiyo's Duel Runner, he and the others learn they will be facing them in the quarterfinals.

As Team 5D's prepares to go against Team Taiyo, they grow curious from having seen their deck, which consists of mostly normal cards. Taro recalls how he managed to get his team together and enter into the WRGP. The first round starts with Jack going against Yoshizo. Yoshizo brings out Holding Hands Majin to solidify his defense, even managing to defend against Red Dragon Archfiend. It soon becomes apparent that Taiyo's plan is to provide an invincible defense whilst attacking with Speed World 2's effects. Jack manages to equalize their life points, and soon manages to negate Holding Hands Majin's effect and destroy it, however, Team Taiyo have another plan waiting.

Jack beats Yoshizo by countering against Speed World 2's effects, and now faces against Team Taiyo's second member, Junbei, who summons another Holdin Hands Majin. Junbei remembers when he got mad and ran away from home, encountering a man named Mizuru in a sports car. Whilst accompanying him, Mizuru knocks a thug member's duel runner and is chased. When some of Mizuru's friends get captured and Mizuru is too scared to go back, Junbei goes back to face the thugs, and is rescued by Taro and Yoshizo. Back in the present, Jack tries a trick to knock both him and Junbei out, but Junbei manages to survive the attack. Crow continues the battle, who uses the combined efforts of Blackwing Armor Master and Black-Winged Dragon to defeat Junbei. As Taro enters the duel, Yusei suspects that Taro has a plan that will cause them to lose within a few turns.
