He also says that he doesn ' t know what happened to the people who were sacrificed to the Earthbound Immortals . He then asks them , if they are ready to fight .

He is mistaken by Crow to be a Dark Signer . After everything is explained , they duel . Lazar at first attacks him successfully and gets confident , however Crow manages to turn the duel around . As the two of them hold out to win , the duel gets interrupted by the Dark Signers ' dark mist ritual which makes Lazar run away from the duel leaving Crow behind . Crow tries to escape with his Duel Runner from the dark mist that ' s enveloping Satellite . However it ' s of no use as the mist gets him along with many other Satellite residents . Because of this ritual , all of Satellite becomes enclosed , prompting the Signers in response to , along with Leo and Mina , board a helicopter bound for Satellite , flown by Trudge himself . Once there , Martha and Blister , along with other children , greet them . However , the reunion is cut short as Yusei finds out that Rally and the others along with Crow have disappeared . That night , Yusei battles in a fierce Shadow Duel against Roman while trying to protect 3 children from Martha ' s home that had followed him to their dueling site from being sacrificed to the Earthbound Immortal . When the leader of the Dark Signers activates a trap that will allow him to Special Summon his Spider God straight from the Deck , both Akiza and Yusei fear that it will absorb the kids ' souls as sacrifices . Half way in to the duel , Roman talks about the Zero Reverse and Yusei ' s parents , and that Rex Goodwin is his brother . The Earthbound Immortal Uru is Special Summoned . As the souls of the two children near the duel are about to be absorbed by the Earthbound Immortal , Jack appears saving the children just in time . Uru then launches an attack which Yusei deflects , only to end up with the attack hitting the building where Martha , Trudge , and the third kid are watching the proceedings from the roof . The building starts falling over and Martha saves the third child from falling off only to end up falling over the side herself , getting sacrificed to the Earthbound Immortal . This act pushes Yusei to the brink of despair . Yusei makes a dramatic comeback , summoning " Stardust Dragon " , only to have Roman reveal that this whole time , he was not the one dueling . This whole time Yusei was dueling Rally in disguise , unconscious and unaware of what was going on . Once Roman removes his mind control over Rally , he , knowing someone has to die , decides to sacrifice himself to save Yusei by Synchro Summoning one - shot booster and using its effect to destroy Uru inflicting 3000 damage to himself . After the duel concludes , the rest of the Dark Signers show themselves to their rivals , the Signers , as their final battles are about to begin . While chasing after them , Jack discovers one of the Dark Signers is Carly . Later on after each one of the Signers is set on defeating their respective opponent , they split up in order to get to each one of the original Ener - D reactor control units . As each are particularly located outside of where the reactor itself resides , they are each are marked with a corresponding Geoglyph . Those being the Giant , Lizard , Hummingbird and finally the Monkey . As Luna and Leo are taken by Trudge to where Devack is waiting , Luna suddenly vanishes in a flash of light , traveling to the Spirit World in order to free Ancient Fairy Dragon . With Luna missing , Leo decides to duel Devack in her place , trying to fulfill his promise of protecting her . Leo barely manages to hold his own against Devack , though since he is not a signer , the prospect of winning is slim . While Leo is dueling , Luna searches for Regulus , dodging Zeman the Ape King ' s minions . She finally finds Regulus with help from a spellcaster spirit named Torunka . After some concurring events Luna reveals to the White Lion , her identity as one of the Signers , along with the promise she made to the Dragon ' s spirit long ago . Together they get to Zeman ' s castle , trying to trick him into releasing Ancient Fairy Dragon . Hovewer , Zeman finds out they were trying to trick him and orders his army to attack them . Zeman , who is also battling Leo in the real world as a dark Synchro Monster at the same time , gets killed simultaneously in both worlds by Regulus and Leo . Devack in the real world then summons his Earthbound Immortal Cusillu , sacrificing the souls of captured duel monster spirits to do so . He attacks Leo directly , who withstands the attack but gets stuck under a rock . In the spirit world , Torunka sends Luna back to the real world , where she duels Devack in her brother ' s place using his Deck . Devack summons Ancient Fairy Dragon and sacrifices it to activate Cusillu ' s effect . Luna uses the opportunity to rescue Ancient Fairy Dragon and defeats Devack with her brother ' s help , freeing all the sacrificed creature spirits . Ancient Fairy and Regulus join Luna ' s Deck , and the Monkey control unit is shut down . Crow somehow managed to have survived the black fog by hiding in a refrigerator , but realizes all the children he was caring for has disappeared because of it . Taking his anger out on the Dark Signers , he runs into Greiger , who had just become a Dark Signer in order to exact his revenge against Goodwin and Yusei , and immediately challenges him to a Manual Turbo Duel . Discovering the new Geoglyph , Yusei chases up to the two and tries to talk them out of it . Crow begs him to just watch his duel , and Yusei allows them to continue . After his key card is defeated , Greiger retaliates by summoning out his Earthbound Immortal Chacu Challhua . Much to every ones surprise they all realize that the souls sacrificed for its summoning were the people who had disappeared from Greiger ' s village supposedly during a summoning of the Crimson Dragon . Greiger , realizing it was the Dark Signers ' fault after all , tries to stop the duel himself , but then is possessed by an unknown and evil entity who takes over his body . The entity tries to crush Crow with the Nazca God but gets defeated . Eventually the souls are freed with Chacu Challhua ' s destruction , however Greiger , being defeated , withers into dust but not before making peace with both Crow and Yusei . With his detours settled , Yusei finally reaches the Giant ' s control unit , to face Kalin ( Kiryu in Japan ) . Their duel is intense as Yusei tries to save him while Kalin just wants revenge . As more of the Enforcers ' past is revealed including Kalin ' s final moments before becoming a Dark Signer , he Summons Ccapac Apu and tries to destroy Yusei with it . However , though Yusei manages to fend off attacks from the Earthbound Immortal ' s assault , the attacks leave the ground trashed . Kalin has difficulties maneuvering and goes off the road . Yusei tries to save him by Synchro Summoning Majestic Star Dragon and take down Ccapac Apu . Kalin makes peace with him then withers into dust . The Giant ' s control unit is then shut down by Yusei . After the battle , Roman speaks to Yusei through a once again mind controlled Trudge . Roman claims that he ' s the next one Yusei should face against . Yusei along with Crow , Luna , Leo and Trudge , travels to the Original Ener - D Reactor . They meet with Roman inside . The Dark Signer blows the original Ener - D Reactor , releasing the negative energy inside . As it fills the room , the two of them stand on a bridge inside the base and finally begin their rematch . During the duel , Roman not only tells the accounts of the events that lead him to become a Dark Signer , but also that he " was " the the Fifth Signer , possessing the Head of the Crimson Dragon , until he tore off his own arm . He also finally reveals that he was responsible for the Zero Reverse incident , he being the one who overloaded the reactor to kill himself , becoming a dark signer and releasing the Earthbound Immortals to begin again the 5 , 000 year old ancient battle between the Nazca Gods and the Crimson Dragon . Though in desperate straits , Yusei in the end defeats Roman with Stardust Dragon . Roman , before fading away , detonates his robotic left arm , destroying the bridge they were dueling on and causing Yusei to fall in the energy below . Yusei enters a dreadful world filled with the spirits of those who died during the zero reverse . Yusei meets his father who warns him of the rise of the King of the Netherworld . Yusei ' s father then sends him back to the world of the living . Mean while Jack , who has finally reached the Hummingbird control unit , looks surprised as Carly appears , riding her own Dark Duel Runner . They engage in a Shadow Turbo Duel . Carly states that it was Jack ' s fault she became a Bark Signer and makes the first move , ( in the dub she calls him " Jackie " . ) As the duel proceeds Carly attacks mercilessly , countering Jack ' s every move . After degrading most of his lifepoints , Carly activates a trap card , putting Jack into an illusion of losing the duel and gets saved by Carly , turning him into a Dark Signer and King of the hellish world where the Signers have lost . While being carried by an army of mummies , Jack remembers dropping Carly ' s glasses and snaps out of the illusion in time to cancel the effect of Carly ' s trap card . Knowing the real Carly is still here , Jack activates his trap where Carly can choose whether to win or lose . She decides to win but remembers all that Jack has done for her and is able to turn back to her former self . However , once again as with Greiger , a dark and evil entity takes over her and so the duel is forced to go on . She is able to summon her " Earthbound Immortal Aslla piscu " , but her attack is stopped thanks to " Battle Fader ' s " effect . With the help of the Crimson Dragon , Jack manages to turn the situation by summoning " Majestic Red Dragon " . Jack tries to end the Duel with a tie by destroying his " Majestic Red Dragon " , and before he can do it , he instead ends up winning , as Carly intentionally depletes her own Life Points . Thus upon losing the duel , Carly vanishes , just before stating that her final wish was for Jack to become king again , and will be rooting for him all the way . Finally Misty , who is guarding the last control unit , awaits for Akiza while mourning for her dead brother , Toby . Eventually Akiza and Mina arrive where the Lizard control unit is situated , in an old and abandoned carnival . As the two of them split up and look for Misty , Sayer reappears , posing as a security agent from Goodwin . He tricks Mina and throws her into a pit . Yusei , Luna , Leo and Trudge soon arrive and split up to look for Mina and Akiza . Akiza is guided by Misty into a House of Mirror where they finally commenced their rematch . As it begins , Misty recounts the events that lead up to Toby ’ s death that undoubtedly involves Akiza , through the use of her Sad Story Spells and Bad End Trap . Meanwhile Sayer corners Yusei and attacks him with a materialized Psychic sword . He traps Yusei in the same pit as Mina , sealing it shut while flooding it with water . He goes where the duel is taking place , while Akiza who is now tormented by the truth , loses the will to continue the duel . Sayer appears to save her from landing into a shard of shattered glass , instead deviously awakens her powers as the Black Rose once again . Misty summons her powerful Dragon Queen of Tragic Endings , and Akiza responds by unleashing her Black Rose Dragon , shattering every mirror in the vicinity and is finally able to confront her opponent face to face . Misty continues her duel against Akiza with Bad End Queen Dragon and manages to gain the upper hand by summoning her Earthbound Immortal Ccarayhua . While she does that , Yusei tricks Sayer in to revealing the truth behind her brother ' s death . Yusei does this by using his Duel Disk which was still connected to use it to transfer the recording of Sayer saying he was the one who did it . Upon hearing this she commands her monster to devour him and avenges her brother ' s death . Before she could surrender the evil entity of the Underworld takes control and tries to finish Akiza off with a direct attack , but Akiza pulls through by blocking the attack and summoning Black Rose Dragon again to destroy everything on the field . Misty tries to counter by inflicting damage through a card effect , but Akiza counters the damage and deals it back to her , ending the duel with Misty feeling at peace . Misty vanishes , leaving behind the musical locket of Misty and Toby . Because Akiza failed to seal the final control unit before sundown , the Condor geoglyph appears on the sky . Then the Crimson Dragon appears once again and guides the Signers to Rex Goodwin . He reveals to them that he has acquired the powers of both Signer and Dark Signer . He intends to use the power of the Crimson Dragon along with that of the Wicked Gods in order to become the Ultimate God . As the Condor mark on his back shows itself , he declares that a Shadow Turbo Duel will be held within the Condor geoglyph as a ritual to welcome the King of the Netherworld . Yusei , Jack , and Crow accept the duel in order to stop the resurrection of the Underworld Ruler . As the duel rages fiercely upon them and Goodwin , both Jack and Crow are unable to continue due to Goodwin´s , Earthbound Immortal deathly effect , however still in the end Yusei is able to win with their help .
