Yu - Gi - Oh ! 5D ' s - Episode 134 " For Synchro ' s Sake " , known as " Road of Ruin ! A Future Favored by Synchro Summon " in the Japanese version , is the one hundred thirty fourth episode of " Yu - Gi - Oh ! 5D ' s " . Summary . Present . Crow has just Synchro Summon ed " Black - Winged Dragon " and lost to Jakob , who is surprised that someone would sacrifice themself to Summon a Synchro Monster . Crow explains the loss was for the sake of the team . He and his friends aren ' t selfish like Jakob had thought humans were , Crow says , and they share thoughts and fight as one ; That is what they call bonds . Crow exits the circuit , leaving the rest to Yusei . Bruno and Akiza give Yusei some encouragement before he leaves . Yusei nods and asks them to take care of Jack and Crow . With Team 5D ' s down to their last duelist , the MC says that the World Racing Grand Prix final is reaching its climax . Jakob doesn ' t know why Crow left Yusei his Synchro Monster . He says that since it ' s a Synchro Monster it will just become food for " Meklord Emperor Granel " and Yusei will be sent to Hell . Lester mocks Crow ' s move , calling it foolish , but Primo advises Jakob to ignore him and focus on Yusei . He feels Yusei is the real threat , although Lester thinks he ' s overestimating him . At Team 5D ' s station , Akiza asks why Crow Summoned " Black - Winged Dragon " . Bruno isn ' t sure after what happened to " Red Nova Dragon " . He worries that if " Black - Winged Dragon " is likewise absorbed by a " Meklord Emperor " , it will all be over . Crow is now placed in an infirmary with Jack . Stephanie , Carly and Mina worry over Jack ' s bed , leaving Trudge with Crow , who hopes and begs for Yusei will to use the card well . At the Duel , Yusei knows why Crow left " Black - Winged Dragon " to him ; Throughout all the hardship they experienced in the World Racing Grand Prix , they didn ' t fight with their individual Decks , they fought using three Decks . He calls for Jakob to bring it on and the Duel commences . Yusei has 4000 Life Points , while Jakob has 12000 . Yusei begins his turn and both players SPC goes up to 4 . Yusei Summons " Wave Wall " in Defense Mode , Set s 2 cards in his Spell & Trap Card Zone and ends his turn . He looks at " Black - Winged Dragon " and promises that Crow can count on him . Jakob comments that even though his opponent ' s knows the path of their destruction , they still think they can win with Synchro Monsters . He calls them pitiful and prepares to make them disappear . Jakob begins his turn and both players SPC rises to 5 . He plans to feed " Black - Winged Dragon " into " Granel " , who already has 15500 ATK . Bruno worries that if " Granel " inflicts its Piercing damage , Yusei will lose . " Granel " attack s " Black - Winged Dragon " , but Yusei activates the effect of " Wave Wall " . Since he controls a Synchro Monster , he is able to negate the attack . Team 5D ' s get excited . Since " Granel " is five monsters being treated as one , it can only attack once and Yusei is able to negate one attack per turn . Lester says that it ' s not bad and Primo expected at least that much from Yusei . Since his " Meklord Emperor " monster didn ' t destroy the monster it attacked by battle , Jakob activates " Attack Cannon " Releasing " Granel Attack " to destroy " Black - Winged Dragon " . Yusei tells Crow that he can rest at ease and activates " Shadow Impulse " , which is another card Crow left on the field for him . He is able to Summon a Synchro Monster from his Extra Deck with the same Level and Type as the Synchro Monster just destroyed , but its ATK becomes 0 and its effects are negated . He chooses " Stardust Dragon " . Team 5D ' s cheer and Bruno suspects that Yusei is going to evolve it into " Shooting Star Dragon " . Jakob says not to get too conceited for surviving the attack , his bonds are to be destroyed by " Granel " anyway . Regardless of how much it struggles , an ant cannot defeat an elephant , he adds . He elaborates that an elephant will not recognize a small existence like an ant passing by and Team New World are the elephants trying to change history , while Team 5D ' s are just ants who can do nothing but pass by . Jakob revives the left arm of " Granel " in a more powerful form , by Summoning " Granel Attack 3 " . Since he has 4 Speed Counter s , Jakob activates " Speed Spell - Silent Burn " which inflicts 300 damage to his opponent for each of his monsters that didn ' t attack . He inflicts 1200 damage to Yusei , telling him to feel the power of an elephant . Yusei swerves for a moment and regains control with his Life Points down to 2800 . Had Yusei crashed there , Jakob says that he would have spared himself further pain that awaits him . Jakob Sets 1 card in his Spell & Trap Card Zone and ends his turn . Yusei refuses to give up against them trying to change history and vows to keep fighting no matter what . This is all foolishness as far as Jakob is concerned . There is no hope for Yusei , he believes and plans to show Yusei what the future is like . The infinity symbol on Jakob ' s mouth cover lights up and a larger infinity symbol appears in the sky . The Signers ' Marks of the Dragon all light up too . Lester and Primo are surprised that Jakob is showing them this and Primo orders him to stop . In the dub , Lester asks what ' s happening , and Primo says that " Jakob is about to enlighten them ! " Future visions . The symbol in the sky activates and Team 5D ' s consciousnesses are transported to another world . The group wonder where they are and Yusei explains that he has seen the scene in this wormhole before . They look below themselves and see Duel Monsters sealed in stone slabs in a red wasteland below them . Jack thinks it looks like a graveyard . Bruno stares at the scene in shock before shadowing his eyes , apparently realizing something . Suddenly Akiza spots the rings from the center New Domino ' s bridge network . Stunned , Yusei tries to convince himself that this is a lie . Primo , Jakob and Lester then appear before them and Jakob explains that they shall be shown the truth of the future . Yusei asks if this is the future of New Domino . Jakob informs him that it all began with Synchro Summon s and the scenery changes to a few years previous . This time the city is brighter and in working order . There are a number of floating structures above the city . A number of Turbo Duel ists and shown on a road all Synchro Summoning . In an arena for ground dueling , a hologram of a cowgirl holds up " Naturia Gaodrake " , while other duelists all around her raise their Synchro Monsters too . Both the world and dueling have evolved and people became more obsessed with dueling , Jakob narrates . Synchro Summoning even became a symbol for this town , he says and Duel Academy is shown , where a teacher is explaining Synchro Summoning by pointing to a projection showing " Plaguespreader Zombie " and " Marauding Captain " being used to Synchro Summon " Ally of Justice Catastor " . At this time , Duel Runner s and Synchro Summons grew rapidly , both of which were linked with Ener - D . The Ener - D ' s rotation speed continually increased as the world evolved , but the evolution was too quick . Lester laughs that the evolution was indeed incredible and keeps laughing , until Primo tells him to shut up . In the dub , after Jakob explains about the evolution of humanity , Lester laughs and says " That ' s right ! but there was a steep price to pay ! and guess who paid it ? ! " and keeps laughing , until Primo responds , " We did ! " . Lester then wails in terror as an army of Meklord Emperor s appear . The people in the city all look up in surprise , but the Meklord Emperors then start attacking and destroy the city . Leo points below to where Lester is visible , running with his mother and father . The present day Lester says that is his memory of this age . Below Lester and his parents are struck by a blast from one of the emperors . Lester survives , but his parents are killed . This part was edited out in the dub , and Lester only alludes to that day " being the end of his childhood " . The scenery changes slightly and Primo says that this is his memory . The memory Primo is with a girl inside a destroyed building , both of them armed . After a Meklord Emperor Granel passes , they both shoot at it , doing some damage . They look at each other in triumph , but then the building is shot at and the girl is killed . As Primo cries out loud , the Meklord Emperor appears in front of him and he shoots at it in anger . Team 5D ' s watch in horror . The greed of humanity had finally reached its peak , Jakob explains , and at that time the Ener - D suddenly became uncontrollable as it reacted to the greed . The Ener - D went berserk and caused explosions all across the world . Yusei accuses Jakob of lying as he refuses to believe Ener - D would go berserk again . Jakob angrily insists that he is telling the truth and shows his memory of the world he considers to have been destroyed by humanity ' s foolishness . The scenery shifts to Jakob in the destroyed world , who is dressed in rags and walking through the destroyed city , devoid of any other people . Present day Jakob says that he was the chosen one , although he didn ' t know if it was through luck or misfortune . As the only survivor , he wandered around , but nobody could hear his voice . Team 5D ' s look at the destroyed world and think " This is our future " , before being transported back to the present . Present . Yusei continues the Duel , wondering if Synchro Summoning will really lead to that world . He decides not to believe it , causing Jakob to ask if he is trying to escape fate . Yusei accuses Jakob of lying about Synchro Summoning causing that future . This kind of ignorance is what led to the destruction , Jakob comments , but Yusei is convinced that they can decide the fate of the future themselves . Yusei begins his turn and both players SPC goes up to 6 . Yusei Summons " Mono Synchron " and uses its effect to change the Level of " Wave Wall " to 1 . Yusei tunes " Wave Wall " to " Mono Synchron " and chants " " Clustering hopes will open the new speed ' s horizon . Become the path its light shines upon . Synchro Summon ! The power of hope , Synchro Tuner , ' Formula Synchron ' . " " as he Synchro Summon s " Formula Synchron " . He believes that their bonds will open the path to a better future and uses his Clear Mind as he tunes " Stardust Dragon " with " Formula Synchron " and chants " " Clustering dreams and hopes will open the door onto evolution . Become the path its light shines upon . Accel Synchro ! Be born ' Shooting Star Dragon ' " " as he Accel Synchro Summon s " Shooting Star Dragon " . Yusei activates the effect of " Shooting Star Dragon " . He can check the top 5 cards on his Deck , shuffle it and " Shooting Star Dragon " can attack once for each Tuner monster among the 5 . He absorbs the other Signers ' brithmarks , forming the complete Mark of the Dragon on his back . The cards Yusei reveals are " Drill Synchron " , " Debris Dragon " , " Nitro Synchron " , " Quickdraw Synchron " and " Effect Veiler " , all of which are Tuner monsters , allowing " Shooting Star Dragon " to attack 5 times . Using its " Stardust Mirage " attack " Shooting Star Dragon " attacks " Granel Attack 3 " , but Jakob uses the effect of " Granel Guard " to redirect the attack to the equipped " Red Nova Dragon " . " Red Nova Dragon " has 3500 ATK , while " Shooting Star Dragon " has only 3300 , but Yusei uses " Synchro Striker Unit " to raise it to 4300 . Due to the effect of " Granel Carrier " , Jakob is able to prevent " Red Nova Dragon " from being destroyed once . But Jakob still takes damage , so his Life Points are lowered to 11200 and the ATK of " Meklord Emperor Granel " becomes 14700 . " Shooting Star Dragon " attacks " Red Nova Dragon " a second time , destroying it . Both Jakob ' s Life Points and the ATK of " Granel " are at 10400 now . " Shooting Star Dragon " proceeds to attack " Granel Attack 3 " , " Granel Top " , dropping Jakob ' s Life Points to 7900 and 4100 respectively . Finally " Shooting Star Dragon " attacks " Meklord Emperor Granel Infinity " , destroying it along with " Granel Guard " and " Granel Carrier " , leaving Jakob with 3900 Life Points . Yusei Sets 2 cards in his Spell & Trap Card Zone and ends his turn . The effect of " Synchro Strike Unit " causes " Shooting Star Dragon " to lose 800 ATK , lowering it to 3500 . Yusei speeds ahead , so that his Duel Runner is beside Jakob ' s and explains that this is their power towards the future ; Synchro Summon and Accel Synchro Summon have stopped Yliaster ' s ambition . Jakob asks if Yusei is sure he wants to see his future that badly . Thanks to Yusei his field is now reduced to a burnt land . This reminds Yusei of the wasteland in the vision of the future . Jakob says not to worry and is joined by Lester and Primo as he says " Aporia will fix that " . Yusei repeats " Aporia ? " , wondering what this is . Jakob explains that he , Lester and Primo are three beings that strive towards justice and bring hope into this world and the time has come for them to become one . The infinity symbol over his mouth glows , followed by a larger one lighting - up in the sky and then the ones over Lester and Primo ' s eyes . Jakob is ejected from his Duel Runner and flies towards the infinity symbol in the sky . He is joined by Lester and Primo , who compliments Jakob and comments that he has finally gotten another chance to settle things with Yusei . Lester and Primo ' s bodies merge into Jakob ' s . His face now bears the three infinity symbols ' from Jakob ' s mouth , Primo ' s right eye and Lester ' s left eye . The three join to form a mask and the body changes form . The mask disappears once the transformation is complete . Yusei looks up in surprise and asks what ' s happening . The combination of the three opens his eyes and identifies himself as Aporia .
