Yu - Gi - Oh ! GX - Episode 128 " A Dimensional Duel " , known as " Gem Beasts VS Cyber End Dragon " in the Japanese version , is the one hundred and twenty - eighth episode of the " Yu - Gi - Oh ! GX " anime . It first aired in Japan on March 21 , 2007 and in the US on November 22 , 2007 . Summary . With the " Rainbow Dragon " tablet fully excavated , Maximillion Pegasus dons a Duel Disk - like device and headset that features painting tools , so that he can create the card . Jaden Yuki arrives at the site where the Sacred Beasts were sealed , but finds he is too late - Marcel Bonaparte is gone and has taken the cards . Upon returning to Duel Academy , he ' s informed by the spirit of Lyman Banner that everyone else has gone to the tennis courts . He hurries there , avoiding Duel Ghoul s , including Dr . Crowler , on the way . With the card art completed , Pegasus sends the data to Dr . Eisenstein so that the card can be made . Zane Truesdale and Jesse Anderson begin their Duel in order to harness enough Duel energy to send the card through the wormhole . Jesse is able to see Zane through a videoscreen , while a hologram appears that allows Zane to see Jesse . When their monsters attacks , the attacks go right through the wormhole into the other side . Axel Brodie and Tyranno Hassleberry leave to stand guard at the entrance to the tennis courts , to prevent any Duel Ghouls from entering . When Zane deals 1600 damage to Jesse with " Cyberdark Dragon " , the sky in the alternate dimension begins to darken as the wormhole widens . Both sides are rallied on , Jesse by Zane ' s skills and Zane by Jesse ' s taunting , and both cause the other a significant amount of damage . Jaden gets cornered by Duel Ghouls , but is saved by Vice - Chancellor Bonaparte , who tells him to use the underground pipelines to get to the tennis courts . Bonaparte goes to distract the Duel Ghouls , and tells Jaden to save his son . Back at the Duel , more Duel Ghouls attempt to break down the door . Axel and Hassleberry exit the gym so that there will be no interference in Jesse and Zane ' s Duel . The Duel Ghouls Summon a variety of monsters to attack them , while Axel and Hassleberry use the size of the corridor to their advantage , as Hassleberry Summons " Black Stego " block their advance , while Axel uses " Flaming Barbed Wire " in offense . Zane and Jesse don ' t finish their Duel , as the wormhole widens enough before they finish . The card was sealed in a capsule , which was placed in a missile . It ' s fired into the wormhole via a fighter jet . The connection with Eisenstein is cut , and he is only able to tell them to give the card " tremendous power " . The Duel Ghouls bust through the door as Axel and Hassleberry rejoin them . The Duel Ghouls block every exit , but Jaden arrives , busting a hole in the ground with " Elemental Hero Neos " . They escape and Marcel contacts them and tells Jaden that he has thirty minutes to get to him . If he does not reach him in time , Marcel will kill all of the Duel Ghouls . However , he wagers that if Jaden wins , he ' ll release them from his control . He also plays the " House of Sand " card and a pyramid - like building rises from the sand , which he intends to use as the site for his confrontation with Jaden . Featured Duel : Zane Truesdale vs .

Since " Crystal Release " was destroyed and sent to the Graveyard , its second effect activates , allowing Jesse to take " Crystal Beast Ruby Carbuncle " from his Deck and place it in his Spell & Trap Card Zone as a Continuous Spell Card . " Chimeratech Overdragon " then attacks directly ( Due to the third effect of " Chimeratech Overdragon " , it can attack a number of times equal to the number of Fusion Material Monsters used for its Fusion Summon , which gives it a total of three attacks ) , but Jesse activates his face - down " Crystal Pair " to place " Crystal Beast Emerald Turtle " from his Deck into his Spell & Trap Card Zone as a Continuous Spell Card in order to prevent himself from taking any further Battle Damage this turn .

Jesse then Sets two cards . Turn 5 : Zane Zane draws . On Zane ' s Standby Phase , the effect of " Future Fusion " activates , Fusion Summoning " Cyber End Dragon " ( 4000 / 2800 ) in Attack Position . Jesse activates his face - down " Crystal Fortress " . Now until the End Phase , monsters on Zane ' s side of the field that have ATK equal to or less than the number of " Crystal Beasts " on Jesse ' s side of the field times 1000 cannot attack . Zane then activates " Power Load " , equipping it to " Cyber End Dragon " and increasing its ATK by 400 by the number of times every other monster Zane controls can attack times 400 ( " Cyber End Dragon " : 4000 → 5600 / 2800 ) .
