Cold was the night as the Divine Temple was beginning to crumple, its energy source, the Ener-D extinguished. Inside the Divine Temple, trying to escape was New Domino City's Turbo Duelist champion and Satellite's Shooting Star, Yusei Fudo.

Yusei Fudo was a young 19-year-old man, not too far away from becoming 20-years-old. Yusei had tan skin, a somewhat muscular looking physique, black hair with gold highlights, and royal blue eyes. The upper layer of his hair juts upward, while the lower layer arches down. On his face was a yellow criminal mark.

Yusei wearied a long-sleeved blue jacket with a high collar and amber gems, over a sleeveless black shirt with a red symbol, and wore gloves below his elbows with an amber gem on them as well. He wore black jeans with amber knee pads, a belt with two Deck holsters hidden under his jacket, and calf-high brown motorcycle boots.

Yusei has lived an interesting life. He was the son of the legendary scientist, Dr. Fudo, the lead developer of the Ener-D. Years ago, an incident known as Zero Reverse happened. It split the Satellite and New Domino City apart. Yusei's father placed Yusei in an escape pod to save his son from being killed in the accident. However, both him and Yusei's mother were killed in Zero Reverse, making Yusei an orphan.

Yusei's escape pod took him to the Satellite Sector, where he was found by a kind woman named Martha, who took him in and raised him. Yusei grew up into a fine young man, growing up with his two best friends, Jack Atlas and Crow Hogan. Growing up, Yusei became interested in auto mechanics, which would eventually help him create his own Duel Runner.

During their teenage years, Yusei, Jack and Crow befriended another young man named Kalin Kessler, with the four forming a group called 'The Enforcers', their goal was to rid Satellite of all Duel Gangs. They dueled all the other Duel Gangs and defeated them, destroying their Duel Disks and take over the regions they ruled over.

Eventually they succeeded and defeated all the Duel Gangs. During the battle with the last Duel Gang, their leader tried to kill Yusei, but Kalin saved him and together with Jack and Crow, they accomplished their goal. Not too long after, Kalin let the power go to his head, he even started dueling children, destroying their Duel Disks and hurting them.

Seeing what they became, Jack and Crow left The Enforcers, leaving Kalin and Yusei as the last members. Later, Sector Security arrived, armed with Duel Runners, and started restoring 'order' to Satellite. Seeing Sector Security, Kalin decided to wage war on them, too thick headed to see that it was a losing battle.

Yusei left in hopes that Kalin wouldn't fight Sector Security alone, but was wrong as Kalin assaulted Sector Security's headquarters. Yusei, Jack and Crow returned to help Kalin escape, but he wanted to fight Security. Obsessed, Kalin murdered a Security Officer, resulting in a fight between Yusei and him.

Later Jack, Crown and Yusei kept Kalin restrained in a room, hoping that Security would abandon their pursuit, but they were relentless. Yusei tried to surrender himself, pretending to be the leader so that Kalin wouldn't be arrested, but they already found and arrested him.

An officer pat Yusei on the shoulder, as if he was thanking him. Kalin, seeing this, thought Yusei betrayed him and tried to attack him. Yusei tried to explain to Kalin, but he was taken away before he could. Later on, Yusei, Jack and Crow heard a rumor that Kalin died in the Facility.

Yusei, Jack and Crow split and went their own ways. Crow met a man named Robert Pearson and joined him on his dream to create Duel Runners for a living and help children make their dreams come true. Yusei hanged out with his friends Rally, Tank, Nervin, Blitz and sometimes Jack. However, Jack and Yusei eventually split and went their own ways.

Yusei, with the help of his friends, created his first Duel Runner. He planned to ride his Duel Runner through Satellite alongside his favorite monster, Stardust Dragon, in order to give hope to all the civilians for a better future. However, one day, Jack contacted Yusei and told him a lie that Rally was captured by thugs and told him to meet him somewhere.

Yusei rushed over on his Duel Runner, meeting Jack and seeing Rally tied up on a boat in the middle of the water. Jack explained that it was him that did that to Rally and gave Yusei a choice, to either duel him or save Rally. Yusei, of course, chose to save his friend instead and went to save Rally.

Taking the chance, Jack stole both Yusei's Duel Runner and his Stardust Dragon and escaped to New Domino City to become the 'Turbo Duel Champion'. Yusei considered the two stolen items to be 'bonds of friendship' and vowed to get them back someday. To accomplish this goal, Yusei created a new Duel Runner with the help of his friends.

Eventually, Yusei's new Duel Runner was ready to go. A few days before it could begin his journey to New Domino City, Yusei met a Security Officer named Trudge, who wanted to arrest Rally for stealing an acceleration chip. Yusei and Trudge had a Turbo Duel, with Yusei emerging as the victor. Trudge let him go, but vowed that the score between them wasn't over.

A few days later, Yusei was ready to travel to New Domino City through a pipeline. However, Trudge showed up and challenged Yusei to another Turbo Duel, losing a second time. Yusei made it to New Domino City and found Jack waiting for him. Jack tossed Yusei's Stardust Dragon to him, saying he doesn't need it, but he refused. Yusei tossed the card back, preferring to duel for the card instead of getting it back. Jack accepted the challenge and took him to New Domino City's Stadium, where the two had their Turbo Duel.

However, their Turbo Duel was interrupted by a creature known as the 'Crimson Dragon', right when the victor was about to be decided. Later on, it would be revealed that Yusei was the winner. The Crimson Dragon's appearance caused a mark to appear on Yusei's right arm. Before questions could be answered, Sector Security arrived and arrested Yusei.

Shipped off to the Facility, Yusei met an old man named Tenzen Yanagi, and a man named Bolt Tanner, a Duelist that Jack defeated. Yusei befriended these two, and eventually became a hero to the criminals in the Facility by defeating the chief, Chief Armstrong. During his time in the Facility, Yanagi told Yusei that he was a 'Signer', someone with the mark of the Crimson Dragon. The mark that appeared on Yusei's arm was the Mark of the Tail, a piece of the Crimson Dragon. There were five Signers in total and Yusei learned that Jack was one as well. So far, Yusei only knew that him and Jack were the only Signers he knew.

By defeating Chief Armstrong, Yusei was released from the Facility, with the first thing on his mind was to get his Duel Runner and Deck back. Bolt Tanner advised Yusei to look for a man named Blister, who can help him get his Duel Runner back. Yusei listened to Bolt and went to a bar called Bootleg, a place where the bartender told him about Blister. Yusei went outside, where Blister actually found him. Blister took Yusei to his place and began helping him plan his break-in to Security's storehouse to get his Duel Runner back. During his stay, Yusei learned of Blister's past as a Duelist.

Blister created Yusei a fake id and found where his Duel Runner was. The next day, Yusei prepared to set out to get his Duel Runner back, but not before he told Blister his reasons. Soon Yusei arrived at a building where his runner was held and late at night, he found it. However, Trudge showed up and challenged Yusei to a third Turbo Duel. Blister showed up and helped Yusei, considering him a friend.

Yusei played a combo that allowed him to Synchro Summon 'Turbo' Warrior'. Seeing he was gonna lose, Trudge tried to cheat by trying to ram his Duel Runner into Yusei's, but Blister kept him from doing that and Yusei defeated Trudge and his SYnchro Monster, 'Goyo Guardian'.

Yusei managed to escape the building and rode through a crowd of Securities. As he does so, he was electrocuted by the securities. Yusei managed to get away from the crowd, but crashes in the alleyway in the tops and falls of his Runner. A pair of twins, a boy and girl named 'Leo' and 'Luna' found him and took him to their home, nursing him back to health, despite Yusei's new criminal mark on his face.

The next day, Yusei woke up, but had amnesia. Leo tried to help Yusei remember who he was, before suggesting having a duel. Yusei agreed and dueled Leo, while Luna watched. Leo had potential, but had a long way to go.

Yusei defeated Leo in a single turn by using his Synchro Monster 'Nitro Warrior'. At first Leo was sad, but Luna and Yusei cheered him up because Yusei remembered who he was.

Leo wanted to be Yusei's friend, but he told them it would be better if they didn't know him. Luna asked Yusei to spend the night, which he agreed. Once the twins were asleep, Yusei did some work on their Duel Disks as his way to say 'thanks' to them, before he left. Outside, Yusei ran into Trudge again, much to his annoyance. However before they could Turbo Duel, a man known as Lazar appeared and gave Yusei an invitation to the Fortune Cup.

Lazar told Yusei if he didn't enter, his friends back in Satellite would be punished for his actions. Left with no choice, Yusei entered the Fortune Cup. During the days waiting for the Fortune Cup, Yusei reunited with Blister, Tanner, Yanagi, Leo, Luna and met their friend Dexter. Even Jack came around and gave Yusei his Stardust Dragon back. Yusei met one more person in the Daimon Arena.

A woman named Akiza Izinski.

At first, Yusei didn't learn her name until the Fortune Cup, but someone about her drew Yusei to her. Soon the Fortune Cup began, with Yusei starting off as the crowd's hated participant because of his criminal mark and that he was from the Satellite. Yusei paid no attention to them, his focus was winning so that he could protect his friends.

Yusei's first and second opponents were the former champion, Hunter Pace and Greiger. Both proved to be powerful opponents, but Yusei still defeated them. Griger defeated Leo, who was pretending to be Luna, who was invited to join the Fortune Cup. Yusei's third opponent was Akiza, who was revealed to be the Black Rose Witch, a Duelist with psychic powers, powers that can make damage real. Akiza turned out to be a Signer like Yusei and Jack, with the mark of the Foot.

Yusei saved Akiza from her hate and freed her. Unknown to Yusei was that this would lead to Akiza falling in love with him. With Akiza defeated, Yusei would advance on to Duel Jack again. Before that, Yusei went to go see the Director of New Domino City, Red Goodwin to get some answers.

Goodwin used the tournament to gather the Signers from around the world. He succeeded, bringing Yusei, Jack, Akiza and Luna together. Luna had the mark of the Claw and had a special gift, the gift to communicate with Duel Spirits. The fifth Signer's identity would remain a secret for some time.

Jack told Goodwin to let Yusei's friends go, wanting his Turbo Duel against his old friend to just be between him and Yusei. Goodwin agreed and even let Yusei's friend watch the Turbo Duel. During Yusei and Jack's duel, the Crimson Dragon appeared once more when Stardust Dragon and Jack's ace monster, Red Dragon Archfiend clashed. The Crimson Dragon showed Yusei, Jack, Akiza and Luna the past and future, a future where the Satellite was destroyed.

Yusei and Jack continued their Turbo Duel with Yusei emerging as the winner. With Yusei emerging as the winner, he was crowned New Domino City's new Turbo Dueling Champion. A lot of people cheered Yusei's name, while others still hated him. Yusei had bigger things to worry about, for instance, the Dark Signers.

One night, Yusei saw a cloaked figure and chased after him. Yusei dueled this cloaked figure and learn things from him, like there was a group called 'The Dark Signers', a dark version of the Signers. Yusei went to see Goodwin to learn about these 'Dark Signers', thinking he would know.

Yusei had Trudge take him to Lazar, who took him to Goodwin, who was waiting for him at a bridge. Goodwin explains to Yusei that the Dark Signers are the arch nemesis to the Signers, they have revived after 5000 years and possess the soul of the netherworld. When the door to the netherworld opens, the battle between Signers and Dark Signers for the world will begin; This same battle has been repeated over the past five thousand years; In the battle five thousand years ago, the People of the Stars, under the Crimson Dragon, borrowed the power of its servants, the Signer Dragons to seal the wickedness within the Nazca Lines and lock the doors to the netherworld. In that battle, one of the Signer Dragons, Ancient Fairy Dragon was captured. Now after 5000 years, the battle has begun again.

The Nazca lines are formed, each one in the shape of its corresponding monster sealed within. Goodwin explains that afterward the Crimson Dragon was split into five parts and sealed in the human world.

Yusei looked at the dragon birthmark on his arm, now knowing what his mark is. Yusei asked why the battle between the two groups has started again. Goodwin responded by asking Yusei if he knows about the Ener-D. The first Ener-D existed in the depths of Satellite, 17 years ago. Although the control system was perfect, the Ener-D began a negative rotation, whereas it usually has a positive one.

It caused an outburst of energy, which destroyed parts of the Satellite. At that time, a large amount of energy was emitted from Nazca. Goodwin explained that when the Dark Signers appeared, the doors to the underworld are sure to open. Now after five thousand years the seal has been weakened and the Original Ener-D Reactor has started to become a door to the netherworld. To close these doors, they must defeat the gatekeepers, the Dark Signers. The Fortune Cup was held for this purpose, to awaken the Signers' powers.

Remembering his vision of Satellite being destroyed by the Spider, Yusei knew that the battle will be held in Satellite and told Goodwin he must evacuate the citizens. Goodwin replies that he can't do that, for when the people of Satellite are no longer there, the Dark Signers will seek new victims. Yusei cursed Goodwin, saying he built Satellite, knowing this would happen and didn't care if the residents got sacrificed. Goodwin pointed in the direction of Satellite. If Yusei wanted to save Satellite, he must defeat the Dark Signers with their combined powers. To protect his friends, Yusei was willing to battle the Dark Signers himself.

A helicopter with Yusei's Duel Runner appeared in front of the two, with Goodwin telling the fate of the world rest in Yusei's hands. Yusei took the helicopter ride and returned to Satellite, leaving New Domino City. Yusei reunited with Rally, Tank, Nervin, Blitz, Blister, who went to check on Yusei's friends, and Yusei's old friend, Crow.

Crow's friend, Robert Pearson was killed some time ago, leaving the kids he looked after with Crow, along with his Duel Runner. Once heard about the Dark Signers and the fate of the world, Crow joined Yusei in the battle against the Dark Signers. However, their first Dark Signer opponent was someone unexpected.

It was their old Kalin. Somehow he came back from the dead as a Dark Signer to get his revenge on Yusei. The two old friends had a Turbo Duel, where Kalin revealed one of the Dark Signers' secret weapons. A monster called 'Earthbound Immortal Ccapac Apu'. Ccapac Apu was so powerful that it nearly sent Yusei to the netherworld, if it wasn't for Yusei's Duel Runner breaks down and crashes, causing Yusei to fall off, leaving him injured.

A piece of metal had pieced into his abdomen, causing him to bleed. Seeing Yusei's life was in danger, Crow took Yusei to Martha's house on his Duel Runner, while Rally, Tank, Nervin and Blitz would bring Yusei's Duel Runner to the orphanage. During the duel, Jack had arrived in a helicopter and had watched his two friends duel and see Yusei get hurt.

Crow arrived at Martha's house and showed her Yusei. Horrified at seeing Yusei in this condition, Martha and Dr. Schmidt quickly got to work, beginning the operation to save Yusei's life. Luckily, they succeed in saving Yusei's life. Yusei just needed time to rest and recover from his injuries. During that time, Rally and the others arrived with Blister, succeeding in bringing Yusei's Duel Runner.

The next day, Yusei woke up in bed covered in bandages. Martha both scolded Yusei for trying to fight the Dark Signers alone, and gave him advice that he needed his friends by his side to defeat the Dark Signers. Yusei learned his mistake and promised to try not to carry every burden by himself. For the next few days, Yusei rested, recovered and repaired his Duel Runner. He even gave his deck a tune up.

Yusei learned from Blister that the Dark Signers attack the Arcadia Movement, an organization full of psychic Duelists, which Akiza happens to be a part of. They even took down a few buildings and captured 120 people. The Earthbound Immortals required peoples' souls to be summoned and kept the souls, even when the Duel is over.

Two Dark Signers attacked Akiza and the leader of the Arcadia Movement, a man named Sayer. Sayer had disappeared, while Akiza was in the hospital in a coma. Yusei wanted to help Akiza, but his experience with Ccapac Apu and Kalin has shaken his resolve, making him think he couldn't help Akiza.

However, a helicopter came out of nowhere and landed. A man named Hideo came out and requested a talk with Yusei. It turned out, he was actually Akiza's father, and he came to beg for Yusei's help. Hideo explained Akiza's life story, how he wasn't really a good father, his work keeping him from his daughter and the day she received her mark.

Her psychic powers made him fear his daughter so much that he sent her to Duel Academy, thinking it would help her. Instead it made things worse, her powers continued to grow stronger. Eventually, she left Duel Academy and went home. She saw how her parents seemed to be happy without her, making her believe that they didn't want her at all.

Before Hideo could explain, Akiza snapped and shattered the windows with her powers before she left. That was the last time he saw his daughter, before today. Now, he wanted to make things right between him and his daughter. He begged Yusei to come back to New Domino City with him to save Akiza, but Yusei still thought he'd make things worse.

Martha gave Yusei another scolding, before helping him. With his spirit restored, Yusei agreed to help. Martha took the chance to tease Yusei about Akiza, like telling him to take her out on a date. Yusei was a bit surprised by Martha's words, while Blister laugh and Hideo was confused.

Yusei took his deck and Duel Disk and returned to New Domino City with Hideo, reuniting with Jack, Leo and Luna. He also met Akiza's mother and Hideo's wife, Setsuko, but his main focus was on Akiza. She was lying down on a bed with wires attached to her. She hadn't changed from when Yusei last saw her, still incredibly beautiful.

Yusei wiped a tear from Akiza's eye, before his mark activated. Akiza woke up and the first thing she saw was Yusei. At first she was confused, before she went angry at the sight of her parents. Then, Akiza began remembered what happened last night, how Sayer 'died'. Consumed by anger and grief, Akiza lashed out at everyone. Knowing what he needed to do to help Akiza, Yusei challenged her to a duel, which she accepted. Akiza's powers were out of control, dealing more damage to Yusei than in their last duel in the Fortune Cup.

It was a hard fought battle, but Yusei and Hideo managed to get through to Akiza. Akiza reconnected with her family and agreed to help Yusei fight the Dark Signers. The next day, Akiza learned the truth of the Arcadia Movement and of Sayer. He really just wanted her for her powers to conquer the world; he never really cared for her.

Akiza was sad at first, but Yusei cheered her up. Later on, Yusei, Akiza, Leo, Luna and Jack went to Goodwin's mansion. Goodwin led them to the Stairway to the Dragon Star, which was surrounded by a glowing Crimson Dragon glyph. Yusei, Akiza, Leo and Luna were in awe, while Jack wasn't. Soon the Crimson Dragon appeared around the stairway. At the sight of the Crimson Dragon, Yusei and Jack remembered the night when they first saw it.

Goodwin told the two that they had been guided to New Domino City by the Crimson Dragon, but the two disagreed, having come for their own reasons. Goodwin explained to the Signers that the Crimson Dragon has been guiding all of them, even Akiza and Luna. Akiza thought back to her past and how she hurt people with her powers, but was determined to help save the world.

Luna thought back to how she first visited the Spirit World and promised to protect. She even remembered meeting her dragon, 'Ancient Fairy Dragon'. Goodwin told them that they couldn't ignore their destiny and how their gifts brought them all together. The Crimson Dragon disappeared as the Signers marks stopped glowing.

Leo questioned Goodwin about the fifth Signer, getting everyone to remember that they're still missing one. Goodwin told them that the fifth Signer would join them soon. Goodwin showed them the Nazca Lines, right before they disappeared. Goodwin began the story of the Dark Signers and how the Crimson Dragon sealed the ancient evil long ago. As Goodwin continued, the Spider Nazca Line glowed before disappearing.

Yusei thought back to the Duel when he first learned of the Dark Signers and the Duel when he first saw a Dark Tuner Monster and a Dark Synchro Monster, which defied logic with their negative Levels. Since their own dueling is based on the power of life, Goodwin sees it fitting that the Dark Signers' would be based on the powers of the Underworld.

Goodwin explained that when a Dark Signer appears, a geoglyph will surely follow; Goodwin adds and states that their arrival has now put all of New Domino City in a life-or-death crisis. Yusei agreed as he remembered his Duel against Kalin, where people in Satellite were taken in order for Kalin to bring out his Earthbound Immortal. Yusei describes their disappearance as them being slain and was angered that it is being referred to as a sacrifice. Leo and Luna were frightened at hearing this.

Goodwin explained that their actions have already exceeded his calculations; the geoglyphs have appeared in the city too and caused many casualties. Yusei had already assumed this had happened, but was upset at finally hearing the horrible truth confirmed. Goodwin said that the phenomenon Yusei saw in Satellite also occurred in New Domino City and because of the monsters that appeared from the geoglyphs, hundreds of people that were in their vicinity are currently unaccounted for. The Signers and Leo were shocked at hearing this.

The setting around them changed to the Dark Signers attack on the Arcadia Movement building. Goodwin confirmed that the creatures attacking the building are also Earthbound Immortals; creatures which were summoned by the Dark Signers, by sacrificing people. Jack demanded to know what became of those sacrificed. Goodwin however replied that he does not know. Jack was distressed, as he remembered finding glasses, which belonged to a friend of his named Carly, after the Earthbound Immortals' appearance.

Rex said that the situation required immediate action and if they stand idly by, all the people of the Satellite and New Domino City will fall into the clutches of the Dark Signers and the entire city will collapse, just like the vision the Signers had during the Fortune Cup. This information frightened even Luna and Leo, who were worried for the safety of their friend Dexter, Yanagi and Tanner.

Goodwin explained that the only people who can defeat the Dark Signers and save the world from destruction are the Signers. During Goodwin's explanation, Akiza remembered more of her troubled past and how back then, she didn't see life in the city as enjoyable. But since Yusei changed her ways, she now feared for her parents' safety. Jack said that he doesn't care about fate and that he decides what he himself what he should do. Yusei looked at Jack as he remembered what Martha had said about letting his friends help him. He felt that she was right and the upcoming battle cannot be fought alone.

Yusei told everyone about his duel against Kalin and how he would have lost his life if his Duel Runner didn't break down. He also asked if the Dark Signers could return to normal, but Goodwin interrupted him and said that there was no way to revert Dark Signers to their former selves. Yusei asked once again what he meant. Goodwin explained that the Dark Signers are the souls of the dead, who have awakened to their abilities, in other words they were no longer of this world. Everyone got worried over hearing this, but Jack argued back that dead people cannot be brought back to life. Goodwin simply stated that it is. The negative Level of the Dark Synchro Monsters is proof that the Dark Signers are messengers of the Underworld.

Goodwin soon left, but not before encouraging them to keep on fighting to save the world. The Signers kept looking at the Stairway to the Dragon Star for a while, before they left. Yusei was thinking about Kalin and how they were no longer part of this world. Luna tried to cheer him up, but failed.

Soon Jack walked up to Yusei and punched him out of his despair for Kalin's fate, latterly. It took a few punches before Yusei got his act together. Yusei and Jack hanged out at the garden for a while before Akiza, Leo and Luna joined them. Later on, Yusei and Akiza were watching the sunset together from balcony.

The two wondered if they'd see a sunset like this again, before they were called in by Mina, who showed them footage of Satellite. Some kind of mist was covering Satellite from view. Mina told them some sort of abnormality occurred in the deepest part of Satellite, and they are currently unable to contact Sector Security in Satellite and the footage they have may not hold for much longer. Straight away, all screens in front of them lose their signals. Jack refused to do nothing and declares that they were flying to Satellite right away. Yusei was worried about his friends in Satellite, as Mina prepared to execute Jack's plan.

Later on, they met with Goodwin at a rooftop, where the helicopter will take them to the Satellite. Goodwin explained that the original Ener-D was the cause of the mist and that they must get to it. Goodwin even revealed it was created by Yusei's father. Akiza, Leo and Luna were surprised by this revelation, but Goodwin continued on and tells them that their mission is to defeat the Dark Signers and make the Original Ener-D Reactor spin in the right direction.

Soon the helicopter arrived and the pilot turned out to be Trudge. Before they could set off, Yusei told Goodwin if they defeat the Dark Signers, he needed to complete Daedalus Bridge. Goodwin agreed and promised to build the bridge. Hearing those words, Yusei joined the others on the helicopter.

Before they left New Domino City to battle the Dark Signers, Leo and Luna spotted Dexter, Bolt Tanner and Yanagi wishing them good luck for their battle. The twins waved goodbye to their friends as Yusei's resolve increased. Soon they arrived in Satellite and landed by Martha's house, who was happy to see Jack again.

They all gathered in the living room with Martha telling everyone that the mist had taken all of Satellite's people, including Crow, Rally, Tank, Nervin and Blitz. Sad at hearing them gone, Yusei was determined to defeat the Dark Signers and get his friends back. Martha smiled at seeing Yusei back to normal, before she told everyone that she'd be making dinner for them before they left to battle the Dark Signers.

Martha had Trudge join her, who was sad at seeing Mina 'confess' her feelings for Jack, but they weren't returned or acknowledged. Trudge learned a few things from Martha, and from a kid who wanted to join Sector Security someday. Everyone soon had a peaceful dinner, where Yusei told the kids that the bridge connecting Satellite and New Domino City would soon be complete and that they could be whatever they wanted in the future.

The kids were happy to hear that, calling Yusei cool. However, an unwelcomed guest appeared out of nowhere. It was the leader of the Dark Signers, the Dark Signer of the Spider, Roman. Roman came to challenge Yusei to a Duel, who agreed and lead him away so that the others wouldn't be absorbed by Roman's Earthbound Immortal. Akiza followed Yusei, wanting to support him in his Duel against Roman.

Jack led the others to a safe room, but unknown to them, Yusei and Akiza, three of the orphans that Martha takes care of went after Yusei. Their names were Taka, Mitch and John. Far from the orphanage, Yusei and Roman began their Duel with the pillar of fire surrounding them in the Dark Signer's Spider mark. The Duel started off badly for Yusei because on Roman's first turn, he dealt 2400 points of damage to Yusei. However, Yusei began his counter attack by summon one of his most powerful Synchro Monsters, 'Road Warrior'.

However, John and Mitch arrived and were too close to the fire, which surrounded them. Roman played a Trap known as 'Alter of the Bound Deity', which would allow him to Summon his Earthbound Immortal. Yusei tried to stop him from Summoning his Earthbound Immortal, but failed. John and Mitch's souls were beginning to be absorbed. Martha, who had chased after her kids with Trudge, was horrified at what was happening.

Luckily, a miracle happened. And that miracle's name was Jack Atlast, who appeared riding on his Duel Runner and used his mark to save the two boys' souls. With John and Mitch safe, Yusei focused on Roman and his Earthbound Immortal Uru. Yusei was determined to destroy Ura, but Roman started to tell of his past.

He told Yusei a lie that his own father freed the Earthbound Immortals and how he worked under Dr. Fudo with his younger brother, who was actually Rex Goodwin. Roman told Yusei that it was Dr. Fudo who ordered the development on the Ener-D Reactor be stopped, due to the dangers associated with its negative rotations. Their sponsors and New Domino wouldn't allow that and placed Roman in charge of the project. After that, the Zero Reverse happened. Yusei was angered by what Roman said and demanded answers.

However, Roman decided he's talked enough and continued the Duel against Yusei. Roman tried to defeat Yusei with Uru, but Yusei managed to survive thanks to a Trap called 'Iron Resolve'. Uru's attack shook a building, one where Taka, Martha and Trudge were watching the Duel from.

Trudge and Martha quickly went to the rooftop to save Taka before Uru absorbed him. The rooftop began to slope down, with Taka on the lower end and Trudge and Martha at the higher part. Martha began to climb down and made her way to the boy. Once she reached him, Taka apologized, but Martha said it was okay, as he must be brave in order to join Security. Trudge reached out his hand and helped Taka into the doorway, but Martha slipped and slides to the other end of the roof. She tried to climb back up, but slide down again.

Trudge tried to climb down to help Martha, but she stopped him. Martha told Trudge to look after her children with a smile, despite knowing her fate. Trudge tried to convince her to continue, but he knew she wouldn't be able to escape. Yusei and Jack called out to her, who said she was proud of them and she's sure that they will build the bridge between the city and Satellite. She then slide down and fell off the edge of the building. Before hitting the ground, her body transfigured into a blob of light, and was sucked into Uru.

At seeing this, Yusei cried out in sadness, while Jack gritted his teeth. Everyone, but Roman was sad for what happened to Martha. Yusei's grief was quickly replaced by anger and swore to make Roman pay. Yusei Synchro Summoned his ace, Stardust Dragon and direct attacked Roman, who used a Trap called Spider Egg.

Yusei made sure he was ready for whatever Roman threw at him, but he was expecting Roman free Rally's soul and have him duel for him. Yusei couldn't hurt his friend and Rally knew that, so he Synchro Summon 'Turbo Booster Cannon' and used its ability to destroy Uru and defeat himself.

Yusei quickly ran to Rally's aid as he turned into fog and crumbled away. Yusei screamed out Rally's name as the Signers and Dark Signers gathered. The Signers were ready to battle the Dark Signers and save their world. The Dark Signers left to wait for their Signer opponents at their destined battlefields.

Mina explained that the 'destined battlefields' were actually the four control units of the Original Ener-D Reactor, each of which are codenamed after a Nazca Line. To deactivate the control units, the Signers needed their Synchro Dragon cards, which were the same cards originally used to seal up the controllers. To close the gate to the netherworld, they needed to shut down to control units.

With their plan set, the Signers went off to battle their Dark Signer opponents. Leo and Luna went off to face Devack, the Dark Signer of the Monkey. Leo went first since Luna returned to the Spirit World to help Ancient Fairy Dragon, before she came back and took over. Together, Leo and Luna's ace monsters, 'Power Tool Dragon' and Ancient Fairy Dragon defeated Earthbound Immortal Cusillu and defeated Devack.

Unexpectedly, Crow had survived the black fog by hiding in a refrigerator and joined the battle by Dueling the Dark Signer's new recruit, Greiger, who joined in hopes to get his 'revenge' on Goodwin. The two had a Turbo Duel, with Crow emerging as the victor, freeing the souls in Greiger's Earthbound Immortal Chacu Challhua.

Crow joined up with Yusei, Leo, Luna and Trudge as they went off to face Kalin. Soon they reached the control tower where Kalin was waiting. Yusei and Kalin went straight to their Turbo Duel and Yusei did better than last time, defeating Earthbound Immortal Ccapac Apu with a new monster called 'Majestic Star Dragon', an evolved form of Stardust with the Crimson Dragon's power, freed Kalin from the darkness inside him and activated the tower.

Leo and Luna were happy for Yusei's victory, but celebrations would have to wait because Roman controlled Trudge to send a message to Yusei to come to the original Ener-D Reactor to face him.

With his mind set on defeating Roman, Yusei, Leo, Luna, Crow and Trudge set off towards the original Ener-D Reactor. When they arrived, Crow split up from the group because he spotted something, while Yusei, Leo, Luna and Trudge continue their search and stopped at a bridge and Yusei saw Roman at the end of the bridge. Yusei and Roman had an argument at first, before they started their duel.

Yusei started off strong by Synchro Summoning 'Junk Warrior' and whipping out half of Roman's Life Points, but the leader of the Dark Signers turned things around when he Summon Uru and reduced Yusei's Life Points to a mere 100 Life Points. Despite being hurt, Yusei refused to give up.

Thinking destiny was by his side; Roman revealed the truth about him and the past. Roman actually used to be the fifth Signer, but tore his arm off. He explains that years ago, Dr. Fudo discovered the Planetary Particles. Roman explains that the Planetary Particle, much like a planetary gear, binds particles together with other particles and that Dr. Fudo gave his son the name of his discovery.

He added that Dr. Fudo wished that Yusei could be a person to connect people with each other through bonds. The Planetary Particle was a new, essential particle needed to create Ener-D. The doctor created his own theory and launched development on the non-polluting energy mechanism, the Ener-D Reactor. Rex and Roman were researchers but were impressed by the doctor's research and they were able to become his assistants. The doctor would talk about the possibilities of his research like a bright-eyed little boy. He believed in the world's future that the Ener-D Reactor could create.

However, one night, Dr. Fudo, Rex and Roman were researching until they felt a tremor. Roman looked at the computer screen and saw that the energy gauge showed abnormal figures, but the equipment seemed to be normal, though. They couldn't understand the problem, but back then, no one could think that the Ener-D Reactor would bring about something unprecedented. Because of the experiments, the city was struck by abnormal weather. Roman was shocked when Dr. Fudo decided that the experiments must be stopped.

Dr. Fudo explained that it was out of hand. He didn't know what it's due to, but he's positive that the abnormalities in the city were connected to the Ener-D Reactor. Rex was about to say that all the research will be lost. Dr. Fudo knew that already, but as long as their safety is being threatened, they can't continue to put the citizens in danger. Roman was a little saddened by that development.

Roman investigated every piece of data in the world and he found a location where disasters were occurring at the same time as the experiments, which was the Nazca Lines. He arrived in South America to investigate the Nazca Lines, having heard about the legend that there was a battle of the Gods 5000 years ago there. At the Nazca geoglyphs, he heard that evil beings were sealed inside and that they were locked in battle with the Crimson Dragon for supremacy of the world.

During his investigation, he met a mysterious man who claimed to be from Iliaster. The man told Roman it was a shame that the research on Ener-D would be halted. Roman wondered how the man knew about that, but the stranger simply replies asking whether Roman wished to continue the research. He also added that the research must continue, even if he has to get rid of Dr. Fudo.

Roman asked him what he is talking about. The stranger replies that in the light of Ener-D, there are possibilities that even Roman can't imagine and that the people of Iliaster believe that Roman is a true genius that should be in the first page of the history books. He also adds that Roman had already been chosen. Roman wondered what the stranger meant by that. The stranger replied by pointing at the birthmark on Roman's left arm. Roman looked at his birthmark on his left arm and said that's a birthmark he has ever since he was born. The stranger said that fate has already chosen Roman and that he can't run away from that.

Roman asked the stranger if the 5000 year old battle between the Gods actually existed and if it's going to happen again. The stranger simply replied that is something he should see with his very own eyes with the will of the light of Ener-D.

After that, he laughed and disappeared in a sandstorm. He returned to New Domino City and went to the laboratory to see the Ener-D Reactor to search for the truth in the stranger's claims. Suddenly, dark purple lights strike Roman's eyes and Roman saw visions about the Earthbound Immortals, the Crimson Dragon and their battle. The Ener-D Reactor was a device created to resurrect the 5000 years old battle between the Gods.

Later on, Dr. Fudo tried to shut down the Ener-D research, no matter what the agents said to him. One of the agents told Dr. Fudo that he no longer had the authority to do that and has been relieved of his duties as a member of R.R.D. a while ago. Dr. Fudo cannot believe what he just heard. Another agent told the doctor that they invested a lot in the development of Ener-D and that the successor has already been decided. The successor was revealed to be Roman.

Dr. Fudo questioned Roman what was the meaning of this. Roman replies that Dr. Fudo didn't have the courage to see the truth and told Dr. Fudo that he shall fill that role himself. Dr. Fudo said that he already built control units for the Ener-D Reactor. When he said that Roman couldn't release the seals, Roman showed him the four cards.

The four cards were "Stardust Dragon", "Red Dragon Archfiend", "Black Rose Dragon" and "Ancient Fairy Dragon", which were the seals. Dr. Fudo took the cards and tried to escape. One of the agents shot at him with their ray guns. In his getaway, Dr. Fudo dropped one of the cards; it was Ancient Fairy Dragon's card. Rex found Dr. Fudo badly wounded and tried to help him. Dr Fudo told Rex to try to stop the Ener-D Reactor and gave him the three cards.

Rex searched for his brother in the laboratory. He finally found his brother, who just cut his left arm and put it in a container. Roman gave the container to his brother, saying that someday, the Signers will appear and no matter how many years it may take, Rex must gather them together and defeat him. Rex wondered what his brother was talking about, but Roman told his brother to do what he says.

He added that there are two Gods within his body, but he chose the path of darkness and told his brother to take his left arm and get away from the laboratory, while a small amount of Roman's self remains. He held his brother at gun point, forcing Rex to do what he says. He went into the Ener-D Reactor Control Room and hit the self destruct button, which caused the Zero Reverse, saying that this way, he'll be reborn as a Dark Signer. Before the explosion could kill him, Dr. Fudo put Yusei in a capsule escaping hatch, saving him from the explosion. The Zero Reverse had split the city into two.

Yusei was angered by what Roman revealed and started his counterattack. Yusei used a combo that let him Synchro Summoned Stardust Dragon, lowered Uru's ATK Points and got to attack Uru, destroying him and reducing Roman's Life Points to 0000.

Despite his defeat, Roman laughed, which surprised Yusei. Roman told Yusei that this isn't the end and that an ultimate god has already been unleashed. While explaining this, he slowly turned into dust. He adds that if all four units are not activated before sunset, the King of the Netherworld will be revived. Roman removed the Duel Disk from his wrist, shocking Yusei by his revelation. Roman told Yusei he won't allow him to leave this place and pulled a switch on his mechanical left arm, which allows him to pull it off. It caused the bridge to explode and Yusei to fall from the bridge into the Ener-D's light, which Roman had activated.

Yusei woke up and found himself in a strange place with a dark sky. He wonders if he was dead. Suddenly, ghostly figures emerged from the ground and looked straight at Yusei. One of them took Yusei by the arms. He told them to let him go, but they refused to listen. Suddenly, he sees a vision when the Ener-D exploded, causing the city to be separated and the death of a dozen of citizens of the city.

Yusei concluded that these ghostly figures were in fact the souls of the people killed in Zero Reverse and that an incalculable number of grudge are all focused on him. Suddenly, the ground slowly began to swallow Yusei while the souls continued to advance on him. The souls continued to gather around Yusei, until a voice told them that Yusei was innocent in the involvement of their deaths and that they must release him. The souls did what the voice told them to do and disappeared. Yusei saw a figure in the light, whom tells him that it was too soon for him to be here. Yusei wondered who this figure is, before he was then blinded by the light.

When Yusei awoke, he found himself suspended in midair in the darkness of the Netherworld, until he saw a light. He questioned the light that seemed to be calling him. Yusei began walking and found himself near a river. A light figure appeared and told him that Yusei doesn't belong to this world just yet. Yusei asks the figure who it was, and the light revealed to be his father, Dr. Fudo.

Dr. Fudo apologized to his son, hoping that Yusei can forgive him for burdening him with such an outrageous destiny. Dr. Fudo begins to fade as Yusei begged him to wait. Professor Fudo told his son that destiny can and will be changed as he continued to fade. Yusei continued to pursue his father, begging him not to leave him. Dr. Fudo told his son that he never left his side and will always be with him, until the light covered Yusei.

When Yusei awoke, he was surrounded by Crow, Leo, Luna and Trudge, who were all happy that he came back. Yusei promised to never forget what his father told him. Crow handed Yusei something he found when he was wondering around, a picture of Yusei's family when he was a baby with his mother and father. Till this day, Yusei would always treasure the picture.

Yusei, Crow, Leo, Luna and Trudge left the original Ener-D Reactor and saw the geoglyph of the hummingbird disappear, meaning Jack defeated his opponent. Almost all the Dark Signers were defeated, only one remained. Crow split from the gang to go check on Jack, while Yusei, Trudge, Leo and Luna went to support Akiza in her duel. They soon arrived at the amusement park and split up to search for Akiza and Mina.

Yusei met a mysterious man, who was wearing a hat and glasses, keeping his identity from Yusei. The man claimed to be from Sector Security and that he came here under Goodwin's orders. Yusei, despite feeling like he can't trust the man, decided to trust him. However, that proved to be a mistake.

When Yusei went into a house that the man claimed that he saw movement, he saw Mina below him, unconscious. He tried to save her, but was attacked by the mysterious man. Yusei fought the man, but was neutralized and sent into the cellar with Mina. The mysterious man tried to drown them, leaving them.

However, Trudge showed up and helped free Yusei and Mina from the cellar, right on time. Yusei immediately went out to search for Akiza, but found Leo and Luna. The twins were watching Akiza duel Misty, but she wasn't herself. It was as if the Black Rose Witch had taken over the duel. However, Yusei spotted the mysterious man who attacked him in another building.

The man was actually Sayer, who had survived. Yusei immediately went to confront him, knowing he was responsible for what happened to Akiza. Yusei demanded to know just what Sayer wanted, who told him that he planned to use Akiza to rebuild the Arcadia Movement and get revenge on the Dark Signers. Because of them, Sayer had suffered a scar on his face.

He was mind controlling Akiza to get his revenge. Yusei demanded him to let Akiza go, but he refused and they battled. Despite losing the fight, Yusei had a plan. He secretly connected his Duel Disk to Misty's Duel Disk so that she would listen to their conversation. Yusei tricked Sayer into revealing that he was the one that killed Misty's brother, Toby.

At hearing who was the real killer of her brother, Misty had her Earthbound Immortal Ccarayhua eat him alive. With Sayer gone, Akiza was freed. Misty apologized to Akiza and was about to surrender the Duel, but the darkness took hold of her and forced the Duel to continue. Left with no choice, Akiza defeated the possessed Misty and sent her to the netherworld. All the Dark Signers were at long last, defeated. However, they were too late.

Suddenly, an earthquake strike and a light appeared. Trudge was the first one to notice it and Mina pointed out that it came from the direction of New Domino City. Then, a condor geoglyph appeared in the sky, terrifying everyone with the implications of another Dark Signer. Right at that moment, Jack and Crow showed up.

A mild earthquake broke out right before some multi-colored light was emitting from the crater in the center of the B.A.D.. Yusei figured out that the Doors to the Netherworld have completely opened. Various thunderbolts strike the area around that crater above the former Dark Signers' lair as a dark filthy liquid made its way out of the hole. Two red glowing eyes appeared near the top of the sludge as it took the form of a giant dragon.

The dragon stood over Satellite, dripping sludge, staring in the direction of the Condor lines. Everyone was terrified by the creature's presence. Crow mentioned how Roman had warned them that the King of the Netherworld would appear if they failed to seal the four towers before sunset. Yusei came to the conclusion that this creature must be the King of the Netherworld. Trudge asked if this means it's the end of the world, but Mina replied that they're still here and the darkness hasn't completely taken over.

The Signers' marks glowed as red light shined in the sky, making way for the Crimson Dragon. The Crimson Dragon sent a blast of light at the Signers and their companions. The gang and their Duel Runners had been transported to Goodwin's island residence, where one of the buildings has been smashed, as the Stairway to the Dragon Star has jutted out from underground, breaking through it.

Jack recognized it as the monument that Goodwin had inside his mansion. The Condor geoglyph glowed above the stairway, meaning that the Condor geoglyph they saw in Satellite was above Goodwin's residence. Leo wondered how they got there in such short time.

Rex Goodwin appeared atop the Stairway, welcoming and congratulating the Signers for defeating the Dark Signers, although they were unable to close the Doors of the Netherworld. Yusei asked if what was gonna happen. "The world..." Goodwin began. "... is done for". He finished as he stares at the King of the Netherworld coming in their direction, noting its progress. Yusei questioned why the King is coming here and Goodwin tells Yusei that the stairway is the place for the Divine Ritual. He had used the Crimson Dragon to bring the Signers here for the sake of that ritual.

Rex showed the container that his brother gave him, the container containing the final mark of the Crimson Dragon, the mark of the head. The mark glowed, before the Signers' marks glowed, causing pain for Yusei and the others. Yusei questioned what Goodwin was gonna do with the final mark. Goodwin laughed as he turned around to show the Condor dark mark.

Right in front of their eyes, Goodwin underwent a Dark Signer transformation, before he tore his mechanical arm off and attached his brother's arm to him, using his powers as a Dark Signer. Goodwin was planning on becoming the Ultimate God by using both the powers of the Crimson Dragon and the Earthbound Immortals.

Goodwin announced that the ritual shall be done via a Turbo Duel in the Condor geoglyph. He intended to defeat and sacrifice the Signers to the King of the Netherworld. Yusei, Jack and Crow accepted the challenge and dueled Goodwin. Goodwin proved to be a powerful opponent, especially his Earthbound Immortal Wiraqocha Rasca. He even took the other Signers' marks and reduced Yusei's, Crow's, and Jack's Life Points to 1 point each.

In that Duel, everyone learned that Goodwin was actually the legendary man from Satellite, the one who tried to build the bridge that would connect the Satellite to New Domino City. However, Yusei defeated him with the power of Majestic Star Dragon. The duel wasn't Yusei's only victory, he reconnected Goodwin with his brother, brought back everyone that was a Dark Signer and the Crimson Dragon gifted him with the mark of the head, giving the mark of the tail to Crow, making him the fifth Signer.

With the Dark Signers defeated, New Domino City returned to normal. Majestic Star Dragon took Yusei, Jack and Crow back to the Satellite, where they all finished creating the Daedalus Bridge, finally connecting the Satellite to New Domino City. All three boarded their Duel Runners and rode off to New Domino City, riding off to their new future.
