Yu - Gi - Oh ! ZEXAL - Episode 109 " A Sea of Troubles : Part 2 " , known as " Shark vs . the Roaring Waterfall Deity - Abyss ! Collision , the Two Numbers ! ! " in the Japanese version , is the one hundredth and ninth episode of the " Yu - Gi - Oh ! ZEXAL " anime . It first aired in Japan on June 23 , 2013 and in the United States on May 10 , 2014 . Summary . Abyss orders " Gorgonic Guardian " to attack directly . It swats Shark with its tail , throwing him off his feet and reducing his Life Points to 200 ( the first part of the episode is cut from the dub ) . Elsewhere in the ruins , Dumon confronts Yuma and Astral . Yuma asks if they really need to fight , with Dumon asking why that would be in question . Yuma responds that Dumon had saved them in the past - if he hadn ' t been there in the first set of ruins with them , there ' s no telling what would have happened . Dumon insists they are fated to fight . As he recalls the legends associated with Dumon , Alito , Mizar and Girag , Yuma tells him he ' s sure that the legends of the ruins are about the Barian s and that they were once human just like Yuma - there is no reason for Dumon to fight Astral . Dumon claims he doesn ' t believe they were once human and that the Astral and Barian World s have always opposed each other - there is no way around a fight . Yuma continues , saying that that means neither Dumon nor Astral actually knows why they should fight each other . Dumon actually turns to Astral for backup , saying that they could never live in peace . Astral reveals what he learned earlier - his mission is to destroy the Barian World . As Shark rises to his feet , blue energy emanates from Rio ' s eyes again as Abyss shows him more visions of the past . He finds himself seated on his throne again . He mutters he ' s hallucinating again . Three of his soldiers kneel before him . They explain that their troops are outnumbered at this point and that Vector ' s army have broken through every defensive line due to the presence of the gorgons . It ' s only a matter of time before they make landfall now . Aboard his flagship , Vector laughs maniacally , seated in his own throne . The soldier finishes by grimly declaring that their nation will end up massacred just like their neighbors . Shark doesn ' t have any idea what to do , but Rio steps forward to support him . She states they await his command . Shark is surprised by this and rises from the throne . He yells at Rio not to push their lives upon him . Rio reminds him he is this nation ' s leader - his orders are the orders of its emperor . His soldiers and Rio are confused by his actions now . Rio continues that he is the emperor of the United Nation - he is the one that has to protect this land , as he has in the past . Shark is even more bewildered - did he really unite all these nations together ? Abyss communicates him with him through a mirror , speaking from the mouth of his reflection . He tells Shark to overcome this ordeal - he must win both the Duel and the fight in this vision . Shark angrily tells him to shut up and smashes his reflection with his fist . The mirror has given him an idea though and he fervently states he ' s not fit to be a leader , but he won ' t accept a loss in his Duel or in this world . He tells his aides to arm the men with new equipment . He now finds himself back at the Duel , still confused by the visions as Abyss ends his turn , Rio ' s eyes glowing a brighter blue now . Despite his confusion , he ' s found the visions useful as well . " Gorgonic Guardian " will destroy itself if its ATK falls to 0 . He has just the card to do that with - the " Freezing Point " that he now believes Abyss left in the labyrinth as a test ( in the dub , Shark thinks he has to destroy " Gorgonic Guardian " before it takes him out ) . Shark starts his turn and draws " Freezing Point " . He immediately activate s it . Its effect will reduce the ATK of an Xyz Monster that has no Overlay Units remaining to 0 . As the freezing winds come through , Abyss reminds him that " Gorgonic Guardian " is equip ped with " Xyz Unit " , so if an effect is used that would detach Overlay Units , Abyss can send it to the Graveyard instead . Shark smiles , saying it doesn ' t matter since this isn ' t an effect that detaches - " Xyz Unit " is not an Overlay Unit in that sense ( this effect of " Xyz Unit " is not mentioned in the dub ) . The ATK falls and 0 and Shark declares that the other effect of " Gorgonic Guardian " activates now - monsters with 0 ATK are destroyed . Shark urges it to be destroyed by its own power as its red eye glows and its snake hairs rebound back on it , lancing through and destroying it ( the snakes of " Gorgonic Guardian " piercing through the monster itself is cut from the dub , but the explosion is not ) . Back in the visions , Shark leads a small fleet of ships out to Vector ' s forces . When the gorgons fire their beams , Shark orders his men to deploy their mirror shield s . The blasts are reflected back and all six gorgons are turned to stone before exploding . Shark tells Abyss he doesn ' t know what sort of test this is ( in the dub , Shark asks Abyss on how well he is doing ) , but continues his turn and Normal Summon s " Depth Shark " without Tribute via its own effect as he control s no other cards . He orders " Depth Shark " to attack directly . " Depth Shark " releases a tornado from its mouth at Abyss , reducing him to 2600 Life Points . Finally , Shark Set s a card . Dumon is still speaking with Yuma and Astral . He suggests once again that they settle things now . Astral asks Dumon to answer a question first . He knows Dumon is one of the Seven Barian Emperors and wonders where the remaining two are . There are two that they have yet to meet and logic would dictate their legends would be in this temple . Astral questions why they haven ' t shown themselves yet and as he speaks an overview of Shark ' s Duel is shown . Dumon reveals they are Nash and Marin , the leaders of the group , in fact . Dumon is convinced they are still alive and that they will come back ( Dumon ' s conviction is not mentioned in the dub ) . The three hear a crashing sound and look around . Above them , they can see Shark ' s Duel through a sheen of water that is suddenly projected . The projection fades once they determine what they saw and Yuma wonders why Rio is Shark ' s opponent . Dumon is confused as to why Shark would Duel here and says they ' ll settle this later , quickly flying off towards the inner temple . Yuma yells at Dumon to wait , but slips and falls . He calls Dumon a cheater for flying like that ( in the dub , Yuma calls Dumon a chicken for flying away ) . He says they have to get to Shark . Astral says they must navigate the labyrinth first though . Astral observes that Dumon ' s arrival left a hole in the roof and tells Yuma to take out the " Stinging Swordsman " card ( in the dub , Astral asks if Yuma has a monster that can paddle ) . Yuma is confused , but Astral tells him to just do it , he ' ll explain later . Dumon arrives at the Duel in time for the next turn . Abyss draws and Shark reveals that " Depth Shark " has its ATK doubled during his opponent ' s turn . Abyss believes he has to end the Duel quickly , but wonders how smoothly it will go ( in the dub , Shark adds there is no way that he will lose the Duel ; Abyss disagrees , while addressing Shark as " brother " ) . " Stinging Swordsman " helps Yuma and Astral navigate the labyrinth , using its sword to propel its card base through the water like a rowboat . Astral realizes they can follow the flow of the water that burst in when Dumon entered to the end of the maze . Yuma says the end of the maze is where the water ends . Abyss activates " Gorgonic Ritual , which lets him banish a Rock - Type Xyz Monster from his Graveyard to Special Summon two other Rock - Type monsters from his Graveyard . He banishes " Gorgonic Guardian " to Special Summon " Gorgonic Gargoyle " and " Gorgonic Golem " . He then activates " Gorgonic Pile " , letting him increase the Level s of all " Gorgonic " monsters he controls by the total number of monsters . His two Level 3 monsters become Level 5 . Blue energy emanates from Rio ' s eyes again and Abyss states he ' ll awaken Shark ' s memories . One of Vector ' s soldiers gives him the report that the gorgons have been destroyed by the mirror shields and that the enemy army has now found the will to fight back . Vector orders the soldier killed and his body dumped in the sea . He urges the ocean god to take this blood sacrifice and grant him power ( Vector killing the soldier with a spear and throwing his body into the ocean is cut from the dub ; instead , Vector yells at the soldier to be silent and says that despite Shark ' s army appearing to be confident about victory , they will never stand a chance against him ; he appears to have summoned Abyss without the need of a sacrifice ) . Blue light flies from the ocean and Abyss appears , interspersing itself between the two fleets . Meanwhile , Abyss overlays his two Level 5 monsters to Xyz Summon " " in Attack Position . More blue light emanates from the orb on its head , causing Dumon and Astral to be taken into the past visions as well , while Yuma is just arriving at the Duel . Astral looks around , confused as to why he ' d be in the ruins ' memory . Dumon is also confused , especially about the fact that Shark is in the visions , pinpointing the Barian Emblem pendant around his neck . Rio watches from the castle ' s balcony and realizes the ocean god is on Vector ' s side due to a blood pact . The ocean god fires a blast from its lance , destroying many of Shark ' s ships , then fires another , which lances through the city . Shark is thrown down by one of the blasts and as he rises back up , sees Rio galloping towards the ocean god on a horse . Shark calls to her , but she dismounts her horse and walks towards the god . At the Duel , Rio floats upward and Abyss tells Shark his true ordeal begins now , introducing himself as Abyss as he releases control of Rio and appears before Shark . Abyss activates the effect of " Abyss Splash " , detaching an Overlay Unit to double its ATK until the end of the Battle Phase . He orders it to attack " Depth Shark " with " Final Blow " , firing an energy blast with its lance . Shark activates his face - down " Hide and Shark " as he has 2000 or fewer Life Points . He can banish a " Shark " monster he controls and end the Battle Phase . However , he must also pay half his Life Points . He is engulfed in an explosion and thrown away , chunks of stone flying with him . His Life Points fall to 100 and Abyss states he survived . Shark reveals that the effect of " Hide and Shark " returns to the banished monster to the field now , with its ATK increased by the amount of Life Points he paid . " Depth Shark " returns with 1500 ATK . Abyss ends his turn , but taunts that he won ' t be defeated by that kind of strength ( in the dub , Abyss says " Depth Shark " will live another fight , as does Shark , but Shark will not emerge from this Duel victorious ) . In the visions , Rio is held in the ocean god ' s fist and Vector tells Shark to surrender - if he doesn ' t , his sister will be killed , dropped into a whirlpool in the sea . A neighing sounds out , and Dumon swoops down on his pegasus towards the ocean god . Shark calls to him and Dumon responds that he shouldn ' t be surprised to see him . Did he really think he wouldn ' t come to his dear friend ' s aid ? Shark is confused that they could be friends . Vector orders his archers to shoot Dumon down , but he narrowly avoids the first barrage . The present Dumon is shocked that his past would be linked to Shark ' s - could they really have been friends ? Vector urges Shark to choose - his country or his sister . Rio stands up on the ocean god ' s palm and addresses Shark , telling him that the god has to be purified by a holy sacrifice . Shark asks what she ' s doing and Rio tells she ' ll sacrifice herself to purify Abyss . She leaps into the whirlpool , Shark screaming her name . From it emerges , which Astral believes must be the other " Number " in these ruins . Astral starts a thought and Dumon finishes it - Could Shark and Rio really be Nash and Marin ? At the Duel , Shark falls to his knees , in disbelief of these memories . Abyss tells him the field is the same as what was in his heart - he will lose Rio in this world too . Rio floats off the temple top and falls towards the ground . Shark screams for her , but Yuma runs towards her , yelling " kattobingu ! " and manages to catch her . He twists around , cushioning her fall . Yuma urges Shark to win now - his sister is safe . A card floats down in front of Shark . Grabbing it , he determines it must be Rio ' s . Abyss urges Shark to defeat him and regain his memories - as a emperor , he must lead his people . Shark insists he is no emperor , but draws and then proceeds to equip " Depth Shark " with " Aqua Mirage " . He explains that when he uses the equipped monster as an Overlay Unit , the Equip Card can be treated as a monster of the same Level . " Depth Shark " splits into two . Shark activates " Monster Reborn " , Special Summoning " Black Ray Lancer " from his Graveyard in Attack Position . Finally , he activates his face - down " Full Armored Xyz " . This first lets him target an Xyz Monster he controls . Then , he Xyz Summons another . He overlays his two Level 5 monsters to Xyz Summon " " . Now , he equips " Black Ray Lancer " to " Crystalzero " , increasing its ATK by that of " Black Ray Lancer " , for a total of 4300 . Abyss activates the effect of " Abyss Splash " , detaching an Overlay Unit to double its ATK to 4800 . Calling him naive , Shark activates the effect of " Crystalzero " twice , declaring " Crystal Eraser " . He detaches two Overlay Units to halve the ATK of " Abyss Splash " each time . " Crystalzero " fires a bolt of purple energy from the spear it gained through " Black Ray Lancer " at " Abyss Splash " , reducing its ATK to 1200 . Shark orders an attack with " Crystal Javelin " . " Crystalzero " throws its spear , piercing the orb at the center of the chest of " Abyss Splash " . It explodes and Abyss is thrown backwards , his Life Points falling to 0 . Yuma cheers , while Shark asks Abyss what this was all about . Abyss responds that he was simply following the orders Shark himself had given him to the past . Abyss vanishes , with Shark yelling at him to wait , and his card floats down to Shark , who remarks it is " his Number " . As Dumon departs , he mutters Shark and Rio ' s names . Everyone else vanishes and reappears on the Different Dimension Airship ' s deck , surprising Tori . As Yuma explains what ' s happened to Tori , Shark looks around and finds Rio still unconscious . Elsewhere , Vector is traveling through a portal at high speeds . Don Thousand speaks with him , saying the last two Mythyrian " Numbers " have fallen into the hands of Yuma ' s allies . Vector is angry , but Thousand says it doesn ' t matter - those two will be in their hands soon enough . Vector questions how much Thousand really knows . Thousand responds that he knows everything , including everything about Vector , such as the fact he found out he may have once been human from those ruins . Vector asks if that ' s really true and Thousand reveals that after that , he was reincarnated in the Barian World and ended up killing Nash and Marin . Vector is shocked Thousand would know that , but Thousand tells him the most important thing right now is to locate Number 96 , as he ' s about to make his move .
