Yu - Gi - Oh ! ZEXAL - Episode 139 " The Source Code " , known as " Cut Open a Path to the Future - Astral ' s Determination ! ! " in the Japanese version , is the one hundred and thirty - ninth episode of the " Yu - Gi - Oh ! ZEXAL " anime . It first aired in Japan on February 2 , 2014 and on Hulu on January 4 , 2015 . Summary . Don Thousand muses that Astral finally figured it out . He has no idea where the Numeron Code ' s resting place is , so he made Earth part of the Barian World , allowing him to gain the power of the Numeron Code ( these events are cut from the dub , as they took place in the previous episode ) . The third eye on his forehead glows red as he boasts that once he defeats them , he ' ll obtain its full power - which will make the past and the future his as well . Yuma tells him there is no way they will let that happen , while ( in the dub , Thousand says Yuma ' s and Nash ' s defeats are inevitable ; his destiny is to rule the galaxy , while Yuma scoffs at Thousand ' s remark ) Tori silently urges Yuma , Shark and Astral to protect their future . Yuma Set s a card and ends his turn . Thousand calls them foolish , claiming they are completely powerless before him so long as he has the Numeron Code ( in the dub , Thousand commends Yuma for his spirit , but tells him that his efforts to beat him will be in vain ) . Astral thinks to himself that stretching around them from horizon to horizon is the Field Spell Card , " Numeron Network " . With that card , Thousand has the power to rewrite the Duel to his whim . He muses that if something isn ' t done about that card , they have no chance of victory . Thousand draws , his third eye glowing again . He activate s " Numeron Calling " , prompting more energy to flow through the network below them . He explains that since he controls " Numeron Network " , he can Special Summon four " Numeron " Xyz Monster s from his Extra Deck , as long as they have 1000 or less ATK . He reveals he ' ll be Summoning four " Number s " . Yuma asks " Numbers ! ? " in confusion ( in the dub , Yuma yells that Thousand must be kidding ) , while Thousand raises his arm and the Baria Crystal flower he had used as a cocoon glows with yellow energy before fading away , replaced with a pillar of light . Thousand declares that these four " Numbers " are the first four to have fallen to Earth - they are the guardians of Earth that have watched the planet since that time ( in the dub , Thousand says he had created the first four " Numbers " that the Fearsome Four of the Dark Dueling World used , while yelling for his opponents to witness the true " Numbers " ) . The ground begins to shake as he instructs " " to appear . Yuma remarks that that must be the true " Number 4 " ( in the dub , Yuma comments on the monster ' s large size ) . Thousand continues by ordering " " and " " to manifest themselves . Finally , he claims that this next monster is the very height of " Numeron " . The ground shakes again and Tori falls over , Yuma barely preventing himself from doing the same . Thousand chants , " When this iron - clad door , this monumental gate to hell opens , abandon all hope ! " He Special Summons , " " . " Number 1 " descends behind him , attaching itself to " Number 4 " , as " Number 2 " and " Number 3 " attach themselves to the top of " Number 1 " . Yuma remarks that the " Numbers " combined . Thousand boasts that these cards are appropriate for a god to use - they are the " Numeron Gates " . Tori points out that they each have only 1000 ATK and urges Yuma to beat them . Yuma says that ' s easy for her to say - all they have on the field is the 0 ATK " Ganbara Knight " . Astral adds that its effect has been negate d as well . Nash remarks that there is something odd about those " Numbers " ( in the dub , Nash says they can ' t charge straight ahead to Thousand ' s monsters ) . Astral turns to Yuma and points out that as long as he has other cards on his field , he can ' t use " Numeron Network " to rewrite cards . Yuma cheers at this . Thousand is nonplussed and orders " Ekam " to attack " Ganbara Knight " . The eyes at the top of the gate glow and fire a yellow energy burst . Yuma activates his face - down " Half Unbreak " , prompting a bubble shield to protect " Ganbara Knight " . Yuma explains that this turn , " Ganbara Knight " can ' t be destroyed by battle and any battle damage they take is halved . Their Life Points fall to 3500 and Thousand reminds them that that damage will pour back into the Astral World . Energy pours back from where " Ganbara Knight " stands and shoots through the portal to the Astral World . Explosions riddle the Astral World and Astral ' s eyes widen . As the beams of energy hit the buildings in the Astral World ' s city , Eliphas emerges onto the balcony of the Astral Tower . He remarks that it has begun , then - the battle to decide the future of the Astral and Barian World s . The portal from the Barian World continues to shoot out energy . Thousand urges Astral to watch as he destroys them along with the Astral World . Yuma angrily yells that that ' s a low move . Nash urges him to calm himself - they have to endure his attacks here . Thousand calls them fools for thinking they can endure them and activates the effect of " Ekam " . After it battle s , he can detach an Overlay Unit to double the ATK of all " Numeron " monsters he controls . Nash calls him an idiot and points out that his monsters have no Overlay Units . Thousand laughs and reveals that while he controls " Numeron Network " , " Numeron " Xyz Monsters can use their effects without detaching . Yuma yells " WHAT ! ? " as Thousand ' s third eye glows again . Astral stares down at the energy running through the network below them and suddenly thinks " I see ! " ( in the dub , Astral realizes that " Numeron Network " is powering up Thousand ' s monsters ) . The ATK of all of Thousand ' s monsters doubles to 2000 . Thousand then specifies that each of his " Numbers " has the same effect . Nash remarks that that means that each time he battles , their ATKs double . Yuma thinks they may lose right here , then . Astral turns to Yuma and tells him they cannot win without destroy ing " Numeron Network " . Yuma asks how they can do that - they don ' t even know where the card is . Astral tells him that when the effects of " Numeron Network " activate , lights flash across the network that spans the globe . He adds that they must be drawing the power from the Numeron Code ' s location , meaning that the " Numeron Network " card exists there . Astral addresses both Yuma and Nash , calling the latter " Shark " and telling them it ' s up to them . Thousand mutters Astral ' s name before the the latter flies off in the air , reverting to a beam of blue light and flying into the network . Yuma yells his name , but now Astral streams through the network itself , thinking he must entrust the battle to Yuma and Shark . Thousand calls them foolish again - even if they find and destroy " Numeron Network " , they still cannot win ( in the dub , Thousand calls Astral a coward and knew that it was pointless to resist ) . Thousand instructs them to behold the true form of the " Numeron Gates " . The gate that is " Number 1 " opens and from it emerges a red beast , its limbs pulsing with purple energy . Thousand orders " Dve " to attack " Ganbara Knight " . Yuma asks if that ' s really the gate ' s true form . Nash tells Yuma he has to act now and Yuma specifies that the effect of " Half Unbreak " is still active ( in the dub , Yuma states that the beast took ugly and raised it to a new level , while Nash advises Yuma to get ready ) . The beast fires a blue energy pulse . " Ganbara Knight " is protected , but Yuma and Nash ' s Life Points fall to 2500 and they are both thrown off their feet . Thousand activates the effect of " Dve " , so the ATK of all his monsters doubles to 4000 . Nash says he ' s done it again , but tells Yuma they have to hold on until Astral finds the " Numeron Network " card . Yuma mutters " Shark " as Thousand orders " Trini " to attack " Ganbara Knight " . The beast fires another blast , with " Half Unbreak " protecting " Ganbara Knight " . Their Life Points drop to 500 now and they scream in pain as they ' re taken off their feet again . Tori yells both their names , while Thousand activates the effect of " Trini " , thus doubling the ATK of his monsters to 8000 now . Yuma says he won ' t be able to defend against 8000 ATK . Thousand boasts that it ' s the end now and tells them both to disappear . He orders " Catvari " to attack " Ganbara Knight " . Nash begins his turn and draws . He Normal Summon s " Boom Shark " , explaining that after it battles , it will destroy itself and its ATK will be inflicted to his opponent as damage . He then activates " Aqua Jet " , which will increase the ATK of a WATER monster by 1000 . " Aqua Jet " attaches itself to " Boom Shark " and Yuma cheers - if it attacks directly and then uses its effect , Nash will inflict 4000 damage . Nash responds that he won ' t . Yuma is confused , but Thousand activates the effect of " Numeron Network " . He can send a " Numeron " card from his Deck to the Graveyard to activate that card ' s effect . Energy flows through the network again and Thousand sends the Counter Trap Card " Numeron Spell Revision " to the Graveyard . Now , he can negate the activation of his opponent ' s Spell Card and search his opponent ' s Deck for another Spell Card that can be activated instead . " Aqua Jet " vanishes and is replaced by " Surface " . Nash says the card ' s name and Thousand claims that the card Nash activated was " Surface " , not " Aqua Jet " . Yuma bemoans that he rewrote that card too . Thousand continues that " Surface " will Special Summon a WATER monster from Nash ' s Graveyard in Defense Position . Nash Special Summons " Cutter Shark " in Defense Position . The explosives attached to " Boom Shark " begin to glow and Nash explains that if he controls another monster , " Boom Shark " destroys itself , prompting the monster to explode ( in the dub , Thousand is the one who explains the other effect of " Boom Shark " ) . Within the network , Astral is assaulted by black tentacles . They ensnare him and he screams , but he resolves to keep fighting as Yuma and Nash are . He yells and the tentacles dissolve into energy . Yuma curses , saying that as long as " Numeron Network " is around , they can ' t use their cards freely . Nash urges him not to give up - the Duel isn ' t over yet . Yuma mutters " Shark " and Nash activates " Rank - Up Rising " . He explains that as a WATER monster was destroyed , he can activate this card to add a " Rank - Up - Magic " card from his Deck to his hand . A card appears in Nash ' s hand and he tells Don Thousand to prepare himself as he activates it - " Rank - Up - Magic - The Seventh One " . He Special Summons " " and proceeds to Rank it Up , Special Summoning " " , who appears in Attack Position , twirling its spear . Nash reminds Thousand that the effect of " Numeron Network " can only be used once per turn , so he cannot rewrite another card this turn . Nash activates the effect of " Silent Honor DARK " , detaching all of its Overlay Units to Special Summon " Silent Honor ARK " from his Graveyard . Yuma cheers and Nash declares that both " Silent Honor ARK " and " Silent Honor DARK " will attack . Thousand calls Nash a " cur " and realizes that this was his aim from the beginning . Nash confirms this , saying he let him use " Numeron Network " earlier to set - up this play . Thousand is shocked that Nash wanted him to rewrite " Aqua Jet " ( in the dub , Nash says he was planning on defeating Thousand since his last transformation , while a surprised Thousand mutters that he never thought Nash would defeat him ) . Nash yells that it ends here and orders " Silent Honor ARK " to attack . Pink lasers blast Thousand , reducing his Life Points to 1900 . Nash orders " Silent Honor DARK " to attack , with Yuma adding that this will clinch it . Thousand ' s eyes widen and he activates the effect of the " Numeron Wall " in his hand , Special Summoning it as he took battle damage and ending the Battle Phase as a result . " Numeron Wall " rises in front of Thousand and stops the attack . Nash yells " WHAT ! ? " and Thousand taunts that it ' s unfortunate - a little more and they would have won . Astral is still flying through the network . Seeing a formation of energy ahead , he speeds towards it . Astral remarks he ' s found out - within a blackish sphere of energy floats the " Numeron Network " card . Thousand ' s third eye glows and he asks if he really managed to find it . The indentation between the Duelists is filled with a screen , showing Astral ' s location . Yuma yells Astral ' s name and Thousand remarks how wonderful it is that he managed to find it . Astral claims this is the end for the " Numeron Network " . Thousand asks if Astral thinks he can really destroy it . Astral says he won ' t - he ' ll rip it out of its location and bring it to the Dueling Field ( in the dub , Astral states he will destroy the card ) . Thousand says that he understands now , but reveals that if the card is destroyed , the massive amount of energy stored in it will need somewhere to go - resulting in the energy of the whole network running backwards and destroying the surface world . Yuma mutters " our world " , while Astral ' s eyes widen in shock . Thousand asks what he will do - sacrifice the Earth to save the Astral World ? He reminds him that if " Numeron Network " isn ' t destroyed , he ' ll inflict 50000 damage to Yuma and Nash on his next turn . Yuma mutters Astral ' s name , while Astral thinks that he has to sacrifice something . He reaches his hand towards the sphere , electricity crackling around it . Astral passes through the sphere and tells Yuma and Shark that he believes in them - but this card must be destroyed . He takes the card and throws it - and it lands beneath " Numeron Wall " on Thousand ' s field . Nash stares down at Astral and mutters his name , but says the card ' s on his field now ( in the dub , Nash mutters that Astral brought " Numeron Network " from hiding , but he knows what to do now ) . Astral closes his eyes , but Eliphas appears before him and pushes him from the sphere . Astral asks why he ' d do this . Eliphas holds up a card and states that the Astral World went down the wrong path earlier , but the new powers of " hope " and " the bonds of friendship " were born due to Astral and Yuma ( in the dub , Eliphas says he is atoning for his mistakes ; Astral gave new hope to the Astral World ) . Yuma mutters Eliphas ' name and Eliphas tells Astral that he cannot let himself die just yet . He entrusts the future of what is yet to come to them . Eliphas throws the card to Astral , causing Astral to be taken back out of the network . From the pit emerges a massive spike of energy , which then appears in a sphere and explodes . Yuma backs away and simply asks " What ? " Thousand remarks that Eliphas was an unnecessary imitation ( in the dub , Thousand bitterly curses that Eliphas interfered ) . Astral appears in front of Yuma and Nash , the card Eliphas gave him floating before him . Tears stream down Yuma ' s face . Astral tells them that Eliphas entrusted the future to them - that is why they must not cry ( in the dub , Yuma asks what happened to Eliphas ; Astral replies that Eliphas sacrificed himself to protect Earth , but left them a card to remember him by ) . They now carry the hopes , thoughts and wishes of their countless friends and allies . He tells that they must win this Duel no matter what it takes . Nash declares that he won ' t have to tell him twice and activates the effect of " Silent Honor DARK " . If it ' s destroyed when it has Overlay Units , it revives itself and they gain Life Points equal to its ATK . " Silent Honor DARK " reappears and its spear glows with energy , which radiates out and restores their Life Points to 3300 . Nash Sets a card and ends his turn . Yuma mutters " Shark " ( " Awesome ! " in the dub ) and then declares that they will never lose . Featured Duel : Yuma Tsukumo and Nash vs . Don Thousand . " Duel continues from the previous episode .
