Yu - Gi - Oh ! GX - Episode 029 " Doomsday Duel , Part 1 " , known as " VS Darkness ( First Part ) - Red - Eyes Black Dragon ' s Challenge " in the Japanese version , is the twenty - ninth episode of the " Yu - Gi - Oh ! GX " anime . It first aired in Japan on April 20 , 2005 and in the United States on January 30 , 2006 . Summary . In a dark cave in an unspecified location , a group of figures has gathered . Their leader asks who will be the first to go , and man in a dragon mask steps forward . The leader accepts this , and the man , Nightshroud , vows not to fail , while activating a Duel Disk . At Duel Academy , Chancellor Sheppard stands in his office , and sees a hanglider flying through the air , and believes that the conflict he ' d been anticipating has begun . The hanglider lands near the island ' s volcano , and Nightshroud steps off of it , burning it as he walks away . Around his neck is the second half of the golden pendent that Jaden Yuki received from Gravekeeper ' s Chief , which begins his glow . At the Slifer Red dorm , Jaden is asleep and his half of the pendant also begins to glow . The next day in Professor Banner ' s class , Jaden was sleeping , and wakes up when the lunch bell rings . He beings eating , but Banner informs him he ' ll have to wait , as Chancellor Sheppard wants to see him . He informs Chazz Princeton , Alexis Rhodes , Bastion Misawa have also been called . He accompanies them to Sheppard ' s office , having also been called himself . Outside the door , they meet Dr . Crowler and Zane Truesdale . They enter , and Sheppard informs them of the three Sacred Beasts . He explains that they are powerful cards that sealed underground on the island , and that the academy was built over their resting place . The legend states that if the cards are released , a worldwide catastrophe will occur . Sheppard reveals that a group of people wishing to release the cards have appeared , calling themselves the Shadow Riders . Their identities are unknown , but one of them has already arrived on the island . Sheppard explains that the cards are sealed behind seven pillars known as the Spirit Gates , and each can only be opened with one of the Spirit Keys . He takes out a black box and opens it , revealing the seven keys . He wants each of them to take one of the keys to protect , and explains that unless the keys are won in a Duel , they cannot open the gates . He ' s chosen who he considers to be the five best Duelists at the academy , in addition to two more people , as there are seven Shadow Riders . Each of them agree to take a key , and Jaden states that if were a Shadow Rider , he would target the strongest keyholder first , so he believes he ' ll be targeted early . Crowler believes the same , but thinks either he or Zane should be the first to Duel a Shadow Rider . He informs Jaden that he knows that Zane defeated him in a Duel . Sheppard reminds them that they could be attacked at any time , so they must be careful . That night , Alexis walks towards the Slifer Red dorm , believing Jaden will be the first target , as the Riders will likely challenge who they perceive as the weakest Duelist first . Going by the system the school uses , one would assume it would be Jaden , who is recognizable as a Slifer due to his uniform , unlike Chazz . However , she appears to be too late . She reaches Jaden ' s room in time to be transported along with him to the island ' s volcano , with a platform of light being the only thing separating them from the lava . A dragon made of fire flies from the lava and crashes into the platform . Out of the fire steps Nightshroud , who reveals he has both Syrus and Chumley encased in an orb of light over the lava . It will eventually dissipate , so Jaden must Duel him to save them . He reveals that this will be a Shadow Game and takes out a seemingly blank card , stating that the loser ' s soul will be trapped inside . Jaden thinks back to his previous Shadow Games , and believes he can win this one as well . The Duel begins , and Nightshroud Summons " Troop Dragon " in Defense Position and then Set s a card . Jaden Summons " Elemental HERO Wildheart " , who attacks and destroy s " Troop Dragon " , whose effect activating , letting Nightshroud Special Summon another " Troop Dragon " from his Deck in Defense Position . Nightshroud begins his turn , and activates his face - down " Call of the Haunted " to Special Summon " Troop Dragon " from his Graveyard in Attack Position . He Tribute s both of his " Troop Dragons " to Summon " Red - Eyes Black Dragon " in Attack Position . The fire dragon from earlier bursts from the lava and flies by the light orb that Syrus and Chumley are encased him . Chumley tests the integrity of the orb , and his hand eventually goes right through it . The barrier is starting to weaken . The fire dragon hits the field , and morphs into " Red - Eyes " , who attacks and destroys " Wildheart " . Jaden draws , and then activates " Polymerization " , fusing the " Elemental HERO Clayman " and " Elemental HERO Burstinatrix " from his hand to Fusion Summon " Elemental HERO Rampart Blaster " in Defense Position . Her effect permits her to attack directly while in Defense Position , though the attack power is halved , which Jaden activates now . Nightshroud activates " Inferno Fire Blast " , which inflicts the attack points of " Red - Eyes " to Jaden as damage , at the cost of " Red - Eyes " being unable to declare an attack this turn . This reduces Jaden to 700 Life Points . Nightshroud then Summons " Attachment Dragon " , which he is able to equip to Jaden ' s " Rampart Blaster " , forcing her into Attack Position . The barrier around Syrus and Chumley is weakening further , and they nearly fall out of the hole in one side of it . With the hole there , they can now feel the heat of the fire dragons and lava around them . Featured Duel : Jaden Yuki vs . Nightshroud - Part 1 .

Differences in adaptations . The English version cuts several brief scenes after the opening credits : in the first scene Kagemaru and Shadow Riders have a meeting in an underground cave , and in the second Asuka and Kaiser notice Darkness ' hanglider arrive . In the Japanese version , Cronos accepts his Spirit Key and tells Samejima that he should not have informed the students what they ' ll be facing , as it could frighten them . In the English version , Crowler accepts the key because it is a " posh piece of jewelery " . In the Japanese version , there is a scene in which Judai talks with Sho and Hayato about the Spirit Keys . The topic eventually turns to Kaiser , and there is considerable confusion . Sho usually addresses Judai as " aniki " , which means " big brother " . Judai suggested they wait for someone to challenge Sho ' s aniki , however , he was talking about Sho ' s actual older brother , Kaiser , whom Sho usually addresses as " nii - san " . In the English version , they simply talk about how nervous Jaden should be about facing the Shadow Riders . As Darkness introduces himself in the Japanese version , he reveals that light of his half of the Shadow Charm pendent was what led him to Jaden . In the English version , he states that " the Gravekeeper must be getting sloppy " to have lost to Jaden . Featured cards . The following cards appeared in this episode .
