Yu - Gi - Oh ! ZEXAL - Episode 100 " A Duel in Ruins : Part 2 " , known as " Recollection of Antiquity - Durbe and the White Steed , a Legendary Vision " in the Japanese version , is the one hundredth episode of the " Yu - Gi - Oh ! ZEXAL " anime . It first aired in Japan on April 21 , 2013 and in the United States on March 8 , 2014 . Summary . Yuma ' s Duel with Mach continues , with the lives of Shark and Dumon , who claimed he was Nash , on the line . Rio mutters Shark ' s name ( cut from the dub ) . Yuma commands " Gagaga Magician " to attack Mach ' s Set monster . Its chains transform into lightning bolts that strike the other monster , " Secret Sect Druid Wid " , destroying it . As the monster is destroyed , Dumon and Shark notice one of the other walls opening up a path . They manage to escape in time as Mach says that a hero once said this : " Deep bonds with each other open up paths for each other " ( " The wise Duelist who understands the bond between friends can open up new paths " in the dub ) . Rio is happy that her brother managed to save himself from being crushed . Mach activates the effect of " Wid " , allowing him to activate a Continuous Spell Card from his hand , as " Wid " was destroyed by battle . He activates " Labyrinth of Decisions " . He then sends two cards from his hand to the Graveyard to activate his face - down " Unfair Treaty " . Astral thinks that Mach may be planning something with these cards . Outside the Duel , the ceiling starts to come down on Shark and Dumon . Dumon thinks that if he had his powers , he would be able to escape , but he can ' t , as his Baria Crystal is damaged . Back at the Duel , Yuma tells Shark to hold on and orders " Gagaga Child " to attack Mach directly ( in the dub , Yuma does not refer to " Child " by name ) . " Child " eats another popsicle and blows an icy gust of wind at Mach , reducing his Life Points to 2700 . Another doorway opens for Shark and Dumon . Mach declares that he will activate his two - card combo . As Shark and Dumon escape once again , Mach activates the effect of " Labyrinth of Decisions " ( in the dub , Mach adds that with every move Yuma makes , he ' ll seal the doom of his friends ) ; after an opponent ' s monster battles , he can pay 600 Life Points to have Yuma send a card from his hand to the Graveyard . Yuma repeats the statement in surprise and Mach continues with the effect of " Unfair Treaty " ; whenever Mach would pay Life Points for the effect of a Continuous Spell Card , Yuma must pay the cost instead . Astral finally understands Mach ' s strategy , as Mach urges Yuma to pay the Life Points and discard the card . Yuma complies and discards " Gogogo Golem " . An explosion knocks Yuma back , reducing his Life Points to 3400 . Astral says that Mach ' s strategy is to destroy Yuma ' s hand and Life Points . Yuma asks what kind of test this is . Astral thinks about Mach ' s riddle , " Deep bonds with each other open up paths for each other " , and declares that he finally understands it ( in the dub , Astral does not mention the riddle and instead says that he and Yuma are put in a dire situation ) . When Yuma attacked with his monsters , new paths opened up for Dumon and Shark . Yuma asks what he means . Astral elaborates that with this strategy , Mach can chip away at their Life Points if they attack , and if they don ' t , they will be unable to save Shark and Dumon . Yuma agrees . Mach asks Yuma on what he will do to survive this test ( in the dub , Mach says that Astral is correct , and presents Yuma with two choices : save his Life Points , or save his friends ) . Yuma tells Mach to quit joking ( in the dub , he asks if this is a Duel or a multiple choice test ) and overlays his two Level 4 monsters to Xyz Summon " " . He ends his turn . Mach asks if this is Yuma ' s " Number " and begins his turn ( in the dub , Mach says that Yuma ' s " Number " is impressive , but looks can be deceiving ) . He Normal Summons " Secret Sect Druid Dru " , which appears in a cloud of smoke . He activates its effect , allowing him to Special Summon a " Druid " monster from his Graveyard ; he Special Summons " Wid " . Mach declares that he will finally reveal his " Number " and overlays his two Level 4 monsters to Xyz Summon " " . Astral says that the " Number " finally appeared . Mach says that the " Number " will impose a new trial on Yuma ( in the dub , Astral mutters that " Sky Pegasus " must be the " Number " they are searching for . Mach replies that their search will be in vain unless they pass his test ) . He activates the effect of " Sky Pegasus " , detaching an Overlay Unit to destroy an opponent ' s monster ; he targets " Utopia " for his monster ' s effect . Yuma exclaims , " What ? ! " and Mach continues that Yuma can negate the effect by paying 500 Life Points . Astral tells Yuma that if they lose " Utopia " , they can ' t save Shark and Dumon . Yuma says that he knows and decides to pay 500 Life Points to negate the destruction . Mach activates the other effect of " Sky Pegasus " ; as Yuma paid Life Points , he takes damage equal to the Life Points he paid . The wings of " Sky Pegasus " glow blue and it flies up . It charges towards Yuma , surrounded by yellow energy before ramming him , knocking him back and reducing his Life Points to 2400 . Tori yells Yuma ' s and Astral ' s names . Yuma manages to land on his feet . He comments that if this keeps up , his Life Points will be drained away . Astral adds that " Sky Pegasus " is part of Mach ' s combo as well ( Astral ' s observation is cut from the dub ) . Meanwhile , Shark and Dumon are resting in another room . Shark asks what exactly is going on here , with one trap coming after the other ( in the dub , Shark says that whoever designed the maze had some maze - craze ) . An orb floats down in front of the boys . They run up to it , and Yuma appears on it , engaged in a Duel . This surprises Shark . Rio tells Shark that the Duel just started . Shark says , " What ? " Tori continues that a Number Guardian appeared in front of them . Shark repeats the statement , confused ( in the dub , Rio says that Yuma is trying to save Shark . Her brother asks how Yuma would do that . Tori replies that Yuma has to beat Mach , the knight who trapped Shark . Shark asks what happens if Yuma lost , while also commenting on Mach ' s " goofy - looking armor " ) . Astral informs Shark that the traps set for them are linked to the Duel ; when they attacked , a new door opened up . He also tells Shark about Mach ' s Duel strategy of destroying Yuma ' s Life Points and hand whenever he attacked . Shark curses , muttering that Mach had him and Dumon locked down completely . Yuma tells Shark to hold on because he will save him ( Astral does not tell Shark about Mach ' s strategy in the dub ; Yuma telling Shark to hold on is also cut ) . Mach interrupts him and tells Yuma that once friends are separated , their inner value may come into question ( in the dub , Mach says that even when separated , true friends can help each other ) . Astral repeats the statement in his thoughts . He ponders for a moment , before coming to a conclusion . He asks Shark if he can find any hints on how to win the Duel . Shark repeats the statement and looks around before finding some carvings on a wall . Astral says that this is it , surprising his friends . He continues that Mach ' s trial is some sort of mystery game . If separating the group was the start of the trial , then Shark ' s present location may contain hints to solve the mystery . Rio asks Shark about what he saw on the wall . He replies that he can see pictures and some form of text , but he can ' t read it . Dumon says he can read it , saying that it is a legend about an ancient hero . Shark is surprised that Dumon can understand the script . Dumon continues with the story : long ago , there was a group of knights who defended their land . One of them rode on his beloved steed , a Pegasus . The knights , led by that hero , protected the peace of their country . One day , the hero left the country to return to his hometown . While the hero was gone , the other knights overthrew the king and took over the country . Without the hero , the knights were conceited due to their newfound power and began to call themselves kings . Shark asks who exactly Dumon is , suspicious ( in the dub , Shark calls the story a fairy tale ) . Back at the Duel , Astral asks what the legend is trying to tell them . Dumon says that the rest of the legend isn ' t there . Suddenly , the ceiling above him and Shark starts to crumble . The boys manage to dodge the debris falling on them . Rio yells Shark ' s name and tells Yuma to hurry up and continue the Duel . Yuma agrees and starts his turn . Astral urges Yuma to attack in order to save Shark and Dumon even if it means reducing their Life Points further . Yuma agrees and declares an attack on " Sky Pegasus " with " Utopia " . Mach counters with his face - down " Intrigue Shield " , equipping it to " Sky Pegasus " ; once per turn , it cannot be destroyed by battle and Mach takes no damage from battles involving it . Another path opens up for Shark and Dumon as this happens . After damage calculation , Mach activates the effects of " Labyrinth of Decisions " and " Unfair Treaty " , forcing Yuma to pay 600 Life Points and send a card from his hand to the Graveyard . Yuma sends " Cross Attack " to the Graveyard and his Life Points are reduced to 1800 . The effect of " Sky Pegasus " then inflicts damage to Yuma equal to the Life Points he paid ; Yuma ' s Life Points are further reduced to 1200 . Tori yells Yuma ' s name . Yuma Sets a card and ends his turn . Astral asks Shark if the carvings continue to the other room . The latter confirms it . Dumon continues the story . After hearing about the knights ' rebellion , the hero returned to the castle . He attempted to reason with his comrades that their hearts were filled with justice . The hero also tried to make them remember the bonds that fought together . But the other knights turned their swords against the hero . The hero , refusing to fight back and kill his comrades , was eventually struck down . Suddenly , his Pegasus stepped in and stood in front of the knights in an attempt to protect its master . It continued to fight the knights in its master ' s stead . Yuma asks what happened next . Dumon replies that the story stops there because the mural is too worn out to be legible . Yuma is shocked . Dumon thinks that it ' s as if he knew the legend . He questions if he had been to these ruins before . Mach starts his next turn . He activates the effect of " Sky Pegasus " , detaching an Overlay Unit to try to destroy " Utopia " again . He also reminds Yuma that he can pay 500 Life Points to negate the effect . Shark tells Yuma that if his Life Points decrease further , he can ' t win . He also tells Yuma to let " Utopia " be destroyed and not to worry about him and Dumon . Mach asks Yuma to make his decision . Yuma is frustrated , not knowing what to do . Dumon tells Yuma to pay the 500 Life Points to keep " Utopia " on the field . Shark asks what he means and why Dumon would do this ( in the dub , Shark calls this tactic cowardly ) . He replies that he knows the rest of the legend , surprising Shark ( in the dub , Dumon says that he just remembered the rest of the legend ) . The floor suddenly caves in around the boys . Dumon continues that it was impossible for the hero to abandon his Pegasus . He did remain behind with the Pegasus and eventually passed away . Dumon yells at Shark if he understands . The legend is telling them about one person ' s attitude of believing in protecting one ' s friends . He urges Yuma to protect " Utopia " . Shark still disagrees with Dumon ' s decision and suspects that he must be a Barian . The floor below Shark caves in completely and he falls in , but Dumon manages to grab his hand just in time . Rio yells Shark ' s name . Shark and Dumon , still hanging on for dear life , glow with a magenta aura . Dumon admits to Shark that he is indeed a Barian , as his Baria Crystal is repaired . He undergoes Barian Battlemorph into his true form . Shark recognizes Dumon and tells Yuma not to trust him because he is a Barian . Yuma is shocked by the revelation ( in the dub , Yuma replies that this may be , but Dumon may know something else about the legend ) . Shark warns Yuma not to make the same mistake again . He remembers the time when " Ray Shadows " revealed himself as Vector . Yuma is frustrated at the memory ( Yuma ' s memory of Vector is cut from the dub ) . Astral mutters Yuma ' s name and tells him to trust in himself . Mach asks Yuma if he will get over his trial as " Sky Pegasus " glows with a gold aura and releases a beam of gold light from itself ( in the dub , Mach says that he has waited long enough and urges Yuma to choose now ) . In the end , Yuma decides to pay the 500 Life Point cost to prevent the destruction of " Utopia " . This surprises Shark . Mach activates the other effect of " Sky Pegasus " , inflicting 500 damage to Yuma . Astral , fading in and out , grimly notes that he and Yuma have 200 Life Points left . Suddenly , he realizes something . Dumon manages to pull Shark up to safety , with the latter knocking away the former ' s hand . Shark is frustrated at Yuma for following what Dumon said . Yuma admits that there was no doubt in him and that he did not want to doubt anyone ( in the dub , Yuma says that he has to follow his instinct and Shark has to trust him ) . Shark mutters Yuma ' s name . Yuma begins his turn . Astral tells him that Mach ' s strategy is broken and advises Yuma to attack . Not knowing what Astral was talking about , Yuma agrees and attacks " Sky Pegasus " with " Utopia " . " Intrigue Shield " prevents the destruction of " Sky Pegasus " . As this happens , Dumon guides Shark out of the crumbling room . Mach activates the effect of " Labyrinth of Decisions " and Yuma sends " Hyper Quick ! " to the Graveyard . Rio says that Yuma will lose the Duel at this point . Tori tells her not to worry and that Yuma will not lose ( Tori ' s reply is cut from the dub ) . Rio is surprised that nothing happened to Yuma ; Yuma himself is surprised as well . Astral says that with Yuma ' s Life Points at 200 after protecting " Utopia " twice , he cannot pay the cost of " Labyrinth " , forcing Mach to pay it instead . A Graveyard portal appears and it explodes , knocking Mach back and reducing his Life Points to 2100 . Astral concludes that Yuma ' s decision was right ( in the dub , Astral declares that he and Yuma have the upper hand now ) . Yuma continues his turn by activating the effect of " Hyper Quick ! " When it is sent to the Graveyard , he can draw a card , and if it is a Normal Spell Card , it is treated as a Quick - Play Spell Card . Astral calls this a " destiny draw " , and Yuma draws his card , yelling " kattobingu ! " He draws " Rank - Up - Magic Numeron Force " and activates it , Ranking - Up " Utopia " and performing a Chaos Xyz Evolution to Special Summon " " . Yuma ' s friends are in awe . ( it should be noted that the effect - negating effect of " Numeron Force " is not mentioned at this point ) Yuma activates the effect of " Utopia Ray Victory " , detaching an Overlay Unit to add the ATK of " Sky Pegasus " to its own , declaring " Victory Charge " as he does so . He attacks and destroys " Sky Pegasus " with " Utopia Ray Victory " , declaring " Rising Sun Double Victory Slash " . Mach is knocked back , his Life Points reduced to 0 . Yuma mutters that they won . The path to outside is opened for Shark and Dumon . After the Duel , Mach congratulates Yuma for overcoming the trial . Astral asks Mach if he was the Pegasus who served the hero in the legend ( in the dub , he asks how the legend ended ) . Mach confirms it , as he glows with a turquoise aura . He adds that there is more to the story : the knights were touched by the willingness of the hero and the Pegasus to sacrifice their lives . They regretted their actions and their desire for power vanished . The knights buried the hero and the Pegasus with honor , kneeling before their grave . The hero and the Pegasus then ascended to heaven ( the knight ' s and Pegasus ' grave is cut from the dub ) . Mach advises Yuma and Astral to use their ability to trust others . After this , he vanishes , leaving behind his " Number " card for Yuma to take ( in the dub , Mach says that after all that had happened in the legend , he was left with no master . Yuma ' s belief in his friends move Mach to place himself in Yuma ' s service ) . Shark asks Dumon why he helped them all this time and Dumon says he doesn ' t know . He clarifies that the legend of the ruin may have moved his heart to help Yuma . Yuma then thanks Dumon for explaining the legend to them and because of that , they were able to win the Duel . Dumon says that it was Yuma ' heart that helped him win because he would have trusted without listening to it ( in the dub , Dumon says that even if he had not helped Yuma , Yuma would have put his friends above his own interests ) . He continues that he decided to be nice this time and that they will be enemies again the next time they met before disappearing into a portal . Yuma mutters Dumon ' s name . Then he sees a gold coin nearby , identifying it as a King ' s Coin . Tori asks exactly what it is and Yuma explains that whenever his father would go out to dangerous places , he ' d leave a Coin behind . Tori deduces that Kazuma must have been to these ruins . Yuma theorizes that his father must have been watching them from somewhere all this time . Outside the temple , Yuma tells his friends that the Barians have taken advantage of his ability to trust people and that he can ' t do a thing when he doubts others . He has no choice but to trust other people as a result ( in the dub , Yuma also mentions that Kazuma was like him ) . Astral thinks that it ' s up to Yuma on whether to trust people or not , even if he and Yuma have to take different ways with each other ( in the dub , Astral thinks that Yuma has decided on his own path , but he is uncertain on how he ' ll trust him ) .
