Seasons & episodes

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.

Yusei reveals that Taro's plan is to sacrifice a level 1 monster that has been on the field for ten of his turns so he can summon his trump card, Zushin the Sleeping Giant. When the crowd gets word of this, they start cheering for Team Taiyo, along with the people from their hometown. Crow's attempts to destroy the sacrifice fails, allowing Taro to summon out Zushin, which defeats Crow. Yusei takes over, and brings out Stardust Dragon to battle against Taro.

Yusei manages to deal some damage to Taro, by taking advantage of Stardust Dragon's Defense Mode. As Taro begins his counter attack, Yusei Accel Synchro Summons Shooting Star Dragon. However, Taro activates his own trap, which puts Yusei under the safety line for Speed World 2's effects. Yusei uses the cards leftover from Jack and Crow to negate Zushin's effects, and defeat Taro. Despite their loss, Team Taiyo are praised by the crowd for their efforts. After the defeat of Taro, another part of the Infinity Circuit lights up, and the 3 Emperors of Yliaster gloat about winning the WRGP, and finally setting their plan in motion. Then, the Ark Cradle appears in the sky.

Noticing the appearance of the Ark Cradle (also known as the "Divine Temple") in the sky, Yusei, Jack and Crow go over to investigate, where they run into Team Ragnarok's members, Halldor, Broder and Dragan, who all possess a Rune Eye, similar to the Crimson Dragon marks. Halldor tells them about he got his Rune Eye and his Aesir, later recruiting Dragan and Broder, and uniting them with their powers. Dragan explains that three years ago, his father got hospitalized following a cave in. In order to pay for his hospital bills, Dragan had to follow Goodwin's orders and throw a match against Jack, along with his pride as a duelist. With both sides desiring to fight against Yliaster, the two teams decide to settle things in the semifinals.

Jack gets the truth behind the fixed duels out of Lazar, who confirms what Dragan had told him. Jack becomes irritated as a result, so Yusei suggests he use the WRGP duel to regain his pride. In the match between Team 5D's and Team Ragnarok the next day, Jack and Dragan start off, and are surprised to find out that their starting hands are the same as their previous duel. Realizing the chance to do things properly, the two replicate their first turns from that match, this time, with Dragan being able to use his trap card, which Jack counters with his own. Dragan then brings out his Aesir, Thor, which manages to destroy Jack's Red Dragon Archfiend.

As Dragan continues his attack, Jack starts to take real damage from Thor. However, Jack starts to make a comeback and summons out Red Nova Dragon. However, Dragan activates traps which weaken Red Nova Dragon, and protects Thor. Jack manages to pull off a tactic to return Red Nova Dragon to its full power, destroying Thor and defeating Dragan. However, before he loses, Dragan revives Thor and deals damage to Jack.

Ragnarok's 2nd turbo duelist, Broder, takes over and uses Thor's special abilities to knock Jack out. Crow enters the fight, but his attacks prove ineffective against Broder's traps, and he takes a lot of damage from Thor's attacks. Noticing the support Crow gets from the children, Broder explains how he came across a similar group of children, expressing his desire to fight Yliaster in order to protect them. Crow brings out Black-Winged Dragon, but Broder brings out his Aesir, Loki, which destroys Crow's Black-Winged Dragon.

With just 50 life points left, Crow's supporters almost get into danger while trying to cheer him on, reinvigorating Crow's resolve, and he soon manages to revive Black-Winged Dragon. Then, Crow activates a trap card from the Graveyard, which clashes with Broder's trap, knocking them both out. Yusei begins his round against Halldor, who quickly summons his Aesir, Odin.

Yusei must now face the power of Halldor and all three Aesirs. As Yusei expresses his desire to defeat Yliaster and see his father again, he gains the Seal of the Crimson Dragon, and summons out Majestic Star Dragon. However, Halldor manages to learn Yusei's strategy, and executes a successful counter. Halldor then activates a continuous trap card from his Graveyard, Gjallarhorn.

Yusei faces not only all three Aesirs, but also a countdown from Halldor's trap card, Gjallarhorn, of which the end of the countdown means that the opponent takes damage equal to the combined attack points of all 3 Aesirs, at the cost of removing from play all 3 Aesirs in order to activate the effect, once the countdown has reached its end. At the End Phase of each of Halldor's turns, Gjallarhorn will gain 1 counter, and once it has 3 counters, its effects will activate. Which means that Yusei has only 3 turns to defeat Halldor. Yusei also had to face Halldor's increasing defense. However, Yusei summons out Shooting Star Dragon and deals some damage, before using the trap, Zero Force, to reduce all 3 Aesirs' attack points to 0, resulting in Yusei taking 0 points of damage when the countdown reached its end. Now that all 3 of the Nordic God Cards have been removed from play, Yusei then has Shooting Star Dragon attack Halldor directly, allowing Yusei to win.

Team 5D's have finally beaten Team Ragnarok after an exhausting battle. With this result, the World Racing Grand Prix (WRGP)'s finals will be Team 5D's Vs. Team New World (the 3 emperors of Yliaster). With the finals looming, Carly ponders the possible outcomes of the upcoming battle, while she writes up her special feature article about Team 5D's. While performing the interview, Akiza and company accidentally reconfirm their bonds. Noticing Carly's struggle to write up an article about Team 5D's, not helped by Mina's interference, Akiza, Luna and Leo decide to help her write profiles for each member, recalling on their past adventures. In addition, when Carly talks to Akiza, they discuss the relation of their new opponents, Team New World, to the organization of Yliaster, and the trio's schemes, causing Carly to gain unthinkable information. When Carly was finished typing all of the information down, Stephanie comes in with a teapot full of hot coffee.

In another dimension, Z-ONE (who has now returned to his original form) shows Sherry a vision of the future, where everything on Earth is destroyed because of a global Ener-D explosion. Then, Z-ONE brings Sherry into the Ark Cradle, which is already emerging into the Yu-Gi-Oh! dimension. That night, the Signers are messaged by the 3 emperors of Yliaster, who tell them about the floating metallic island, the Ark Cradle, where a God called Yliadus (Z-ONE's real name) supposedly sleeps, stating that if they win the WRGP, then Yliadus will awaken and have New Domino City destroyed, but will rebuild it the way the trio wants it to be, which is without the existence of Ener-D and Synchro Monsters. During the next morning, the WRGP finals begin with Jack facing off against Lester, who both bring out their ace monsters, Red Nova Dragon and Machine Emperor Skiel Infinity.

The next round starts with Jack facing Primo, who immediately brings out Machine Emperor Wisel Infinity. Primo then manages to bring Jack's life points down to 1,100, through the use of his trap cards, one of which Lester had intended only for Jakob to use. Seeing that Primo was acting on his own again, when Primo activates 2 traps he left for Jakob, Lester get agitated, but when Jakob reminded Primo of their plan, Primo decided to try something different. Yusei realizes their tactic is based on the continuous trap that Lester left behind, but when Jack tries to destroy it, Primo protects it with a trap card, and gets beaten by Jack. But before he loses, Primo then activates another of Lester's continuous traps, Infinite Prison. By sending Wisel Attack 3 to the Graveyard, he can then treat Wise Core as a spell card from the Graveyard, and set it face-down in the face-down zone.

Despite the others' concern for his safety, Crow goes to face Jakob. Crow attempts a technique to utitlize his Synchro Monster's abilities without putting them at risk, by summoning Blackwing Aurora of the Northern Lights, and by activating its special ability, but Jakob counters Crow's stragety by using Scar-Red Nova Dragon as a shield, and by attacking him 2 times with Jack's dragon. Crow is then defeated by Jakob, but manages to summon Black-Winged Dragon in defense mode for Yusei to use, by playing a trap card, after being attacked by Machine Emperor Grannel Infinity. Crow then crashes, and Yusei goes out to face Jakob.

Yusei begins his battle against Jakob, using Crow's trap to bring out Stardust Dragon when Black-Winged Dragon gets destroyed. Jakob then activates a trap, which brings out Grannel Attack 3, while reducing Yusei's life points to 2,800. Jakob shows Yusei and the others a twisted future where New Domino City is completely destroyed. Due to Synchro Monsters and Ener-D evolving the world at an incredible rate, a war broke out and the Ener-D reactor eventually exploded, destroying most of the world. The Yliaster trio also unveil their memmories of despair. In the future, they see everybody Synchro Summoning, and as a result of them using Synchro Monsters to achieve their own greedy desires, the Machine Emperors show up one day, and begin killing humans. In the vision, as Lester was running with his parents to safety, a Grannel shot his parents down. Lester in the vision, then wails at the death of his parents, the ones who loved him.

After introducing himself, the Yliaster trio's duel runners combine to form Aporia's duel runner. Aporia then combines with it in such a way, that the audience are shocked to the point that they begin wondering if he was human at all. Aporia then activates the continuous trap card, Infinite Prison, so that by sending the trap, Infinity Force from his hand to the Graveyard, he can treat Grand Core as a spell card from the graveyard, and then set it face-down in the face-down zone. He then destroys Infinite Prison in order to add Sky Core, Wise Core, and Grand Core to his hand, which had been set face-down. Next, Aporia sends the 3 Machine Emperor Cores to the graveyard, in order to activate the trap card: Genesis of the Machine Emperors, which allows him to special summons his ace monster, Machine Divine Emperor Mechanicle Infinity Cubic. Then, he causes his Machine Divine Emperor to shoot energy into the sky, which results in lightning striking all over New Domino City.

As Yusei continues to defend himself against Aporia's attacks, Jack and Crow come to join him, despite their injuries. They then provide the traps that Yusei needs in order to reflect Mechanicle's attack. But when Aporia negates Mechanicle's destruction, his life points are reduced from 3,900 to 3,400. Yusei then Special Summons Scar-Red Nova Dragon and Black-Winged Dragon, in order to give Shooting Star Dragon attack points up to 9,600. But Aporia manages to counter Yusei's strategy, and has his Machine Divine Emperor Mechanicle Infinity Cubic negate the attack, and absorb both dragons, which increases the Machine Divine Emperor's attack points from 4,000 to 10,300. Aporia then uses a trap, which reduced Yusei's life points from 2,800 down to 400, and allows his life points to rise back up from 3,400 to 4,000. However, thanks to the wishes of the Signers, Yusei is able to draw the cards he needs that are in their possession.

Yusei uses the special ability of Black-Winged Dragon to weaken Machine Divine Emperor Mechanicle Infinity Cube's attack points, and Aporia's life points, both down from 4,000 to 2,600. Then, Yusei defeats Aporia, using the combined might of the 3 Signer Dragons, which causes him to crash into the sea. By this, Team 5D's wins the WRGP finals. Then, the red sky returns to its blue color, and the lightning strikes stop. Then, Team 5D's celebrates their victory during noontime. However, their victory is short-lived, as the Infinity Circuit is complete, and the Ark Cradle breaks through the sky from the "distorted dimension," and it begins to descend towards New Domino City.

Sherry reveals that Z-ONE has shown her the future, and insists that Yusei not board the Ark Cradle, revealing she has switched sides to join Z-ONE, since she was convinced that Yliaster's plan was the only was to prevent the global destruction in the future. She also reveals that now having joined Z-ONE, she will do everything in her power to stop him. Despite this knowledge, Yusei still wants to do something to save the city. Sherry then reports to Z-ONE that Yusei did not heed her warning. When Z-ONE asks why she warned him, Sherry simply replies that the warning will cause Yusei to do something, which would allow her to kill Yusei herself, like to promised herself to. is approached by Team Ragnarok who, with the help of Bruno, manage to use the old Ener-D reactor and Nordic Gods to create a path from Daedelus Bridge to the Ark Cradle. Yusei wants to go on his own, but instead, the rest of Team 5D's joins him, with Bruno in his Vizor form following them.

Team 5D's, and their friends all survive the fall, but get separated into three groups: Yusei with Bruno, Crow with Akiza, and Jack with Leo and Luna. The narrow platforms on which they land on are revealed to be routes leading to the three planetary gears powering the main Ener-D generator, and eventually leading to the Center Gear, which was what they are looking for. Vizor tells them that if they don't reach all 3 gears, then they wouldn't be able to reach the Center Gear, and the Ener-D generator of the Ark Cradle would continue to produce negative energy, which would result in the destruction of New Domino City. Crow and Akiza arrive first at one of the 3 gears, which was the one that was closest to them. But then, they are confronted by Sherry, who reveals that she joined Z-ONE, because he offered her the chance to grant her wish, before challenging them to a duel. Sherry then reveals that her wish is that Z-ONE would bring back her happy days with her family.

Sherry reveals that Z-ONE promised to rewrite her past, so that her parents would never have died if she carried out his plans. She uses the Z-ONE spell card to activate the Soul-Binding Gate field spell, which inflicts 800 points of damage whenever any of them try to summon monsters. As Akiza and Crow defend each other from Sherry's attacks, Sherry tempts Crow with the offer of using Z-ONE's power to change the past, so that Zero Reverse would never happen, so that the children of Satellite wouldn't have been orphans, including Crow, Yusei, and Jack, when they were children, if he surrenders and joins Z-ONE. However, Akiza reminds Crow that he should instead fight for their future, as that was what they as Signers should do. Then, they summon their respective dragons, and use their combined strength to defeat Sherry, which causes the 1st gear to stop rotating.

Jack, Leo and Luna reach the second gear, where they are shocked to see that Aporia has survived the crash, and that he is waiting for them. He forcefully attaches devices onto them, which pierce into their hearts whenever they take damage from the duel, meaning that they will die if their life drops to zero, with the only way of removing them is to defeat him in a three-on-one duel. Aporia activates the field spell Fortissimo the Mobile Fortress, and combines with it. Aporia also sets a trap which blasts players with real damage whenever they summon monsters. Although Leo promises to protect Luna and help Jack, Aporia counters each of his traps, making things worse for his allies. Furthermore, Aporia's attacks leave both Jack and Luna in critical states, and leaves Leo in despair.

As Jack, Leo and Luna struggle to survive, Aporia summons his key monster, Machine Divine Emperor Dragon Asterisk which will inflict 1000 points of damage to anyone who tries to Synchro Summon. Lamenting that he hasn't been able to protect anyone, Leo risks some of his own life points to protect Jack and Luna and weaken Asterisk. Leo then summons Power Tool Dragon and Ancient Fairy Dragon and gets hit by the 4,800 points of effect damage, bringing his life down to zero, causing him to die. The shock of Leo's death puts Luna in a critical state, as her life points gradually starts to drop, as her pulse weakens. However, Leo comes back to life with 100 life points, thanks to Ancient Fairy Dragon, and his Morphtronic Lighton's effect, and becomes the sixth and final Signer, with the Mark of the Crimson Dragon's Heart.

Leo uses Life Stream Dragon to counter Asterisk's, and Fortissimo's damage effects, and to restore everyone's life points to 2,000 (not including Aporia), which puts Luna out of the danger of dying. Seeing that his efforts to inflict damage to the Signers has failed, Aporia gets really agitated. Aporia then activates a trap to prevent Synchro Monsters from attacking, but Luna uses Ancient Fairy Dragon's ability to destroy his field spell, and activate one of her own that supports Synchro Monsters, allowing Jack to bring out Scar-Red Nova Dragon. The destruction of Fortissimo causes the fortress' structure to shake violently, and begin to collapse. Aporia manages to bring out Machine Divine Emperor Mechanicle Infinity Cubic to increase Asterisk's attack points, but Leo and Luna use their traps and dragons' abilities to weaken it. Jack then destroys Asterisk by attacking with Scar-Red Nova Dragon, which defeats Aporia, who falls to his "doom" with a feeling of hope in his heart.
