He tries to think of a plan . After coming up with something he Normal Summon s " Magnen Bar " in Defense Mode and Set s 1 card in his Spell & Trap Card Zone . As he ends his turn , Devack asks if he is at the end of his ropes . Leo promises Luna he ' ll beat Devack for sure . Spirit World . Luna runs through the forest , thinking that she needs to save Ancient Fairy dragon quickly and return to her world or else Leo would be in danger . A flashback then occurs , as Luna recalls a conversaton she had with Ancient Fairy Dragon in the past . Flashback . Ancient Fairy Dragon says to Luna that her servant Regulus should come for her in time , and urging Luna to join forces with Regulus in order to set her free . Present in the Spirit world . Luna wonders if Ancient Fairy Dragon was the one who had called her . She thinks that it will be necessary to free Ancient Fairy Dragon in order to defeat the Earthbound Immortals . Luna and Kuribon reach a town , which appears to be deserted as she walks through it . She notices some spirits , peering at her through worried eyes . Luna asks what they ' re doing , to which they respond by running away . Luna pleads for them to wait , and to please not run away as she runs after them . She eventually gives up and wonders what that was about . She then spots another spirit , which also runs away , leaving Luna tired from running . Luna and Kuribon sit on a bench , wondering why everyone keeps running away . Kuribon senses something and wanders off , with Luna asking what ' s wrong . She gets off the bench and follows Kuribon , who stares into an alley . Seconds later , a ball bounces up towards them from the alley , which Luna catches . Luna is surprised that the ball bounced up a flight of stairs . She spots a staff and after running towards it , sees that even the leave are flying upwards . Luna ponders if in this world things move in the opposite direction and what the staff , which she also has seen in other places throughout the town . As the wind blows hard Luna hears someone shouting " They ' re coming , they ' re coming to catch spirits ! " . As it runs away , it advises the others to do so too . Wondering what this means , Luna turns her head and spots a dark fog emerging from an alley . Luna gets scared and drops the ball , as she and Kuribon run . The ball rolls into the fog , where it is stomped on and burst by a foot . A group of monkeys holding staffs appear and say that they smell the spirits . They then split - up to cover more ground . While hiding scared with Kuribon , Luna asks what that was ( the fog ) . Her pocket suddenly begins to glow and she takes out her Deck . Clasping her hands onto it , she tells the cards not to be afraid . Immediately after she says this , a number of spirits run past Luna , followed by a monkey who spots her and Kuribon . Kuribon , followed by " Sunlight Unicorn " and " Sunny Pixie " , who emerge from Luna ' s Deck , run into the alley way . The monkeys spot them , and one of them fires a blast from a staff at them , despite Luna ' s plea for the monkeys to stop . This seals the spirits within stone tablets , identical in design to Duel Monsters cards , but with their Level Stars reversed , giving them all Negative Level s . One of the monkeys looks at the Kuribon tablet and asks how it feels to be a minus . As Luna tries to figure out what to do next , she is spotted by the monkeys . Luna runs through many places and is eventually cornered by two groups of them . Quickly running into an alley , she finds / reaches a dead end and starts to panic . A stone lining the ground is then lifted up , revealing a spirit , who gestures for Luna to come inside . Satellite . Devack begins his turn . He uses the effect of " Magician Ape " , discarding " Fighter Ape " to take control of " Morphtronic Magnen Bar " . " Magician Ape " raises its staff , which is identical to the ones Luna saw in the Spirit World , and uses its Cursed Needle effect to move " Morphtronic Magnen Bar " to Devack ' s side of the field . Trudge thinks Leo ' s monster has been taken again , but Yusei sees what Leo is doing . Leo laughs that Devack fell for it . With " Magnen I " in Defense Mode , his monsters can ' t attack . Trudge remarks that that wasn ' t bad . Devack however says " Then this intruder will have to disappear " to Leo ' s surprise . Devack Releases it to Summon " Fighter Ape " . Trudge is a bit shocked and points out that it has 1900 ATK . Devack proceeds to attack Leo directly with " Fighter Ape " , but Leo activates " Remake Puzzle " , destroying the " Morphtronic Magnen " on Devack ' s side of the field and ending the Battle Phase . Leo then gets to Special Summon a " Morphtronic " monster with a lower Level than " Magnen " . He selects " Magnen I " and the pieces of the destroyed " Magnen " merge together to form " Magnen I " . Devack remarks that Leo managed to save himself some pain that time , but asks him how long he can keep it up . Devack ends his turn . In his mind , Leo utters " Luna , I ' m trying my best " . Nearby , Akiza , Mina and Jack can see the monkey geoglyph in the sky . However Akiza and Jack are getting no reaction from their birthmarks . Jack suspects that this means whoever is dueling , must not be a Signer . Spirit World . In the alley , the monkeys wonder where Luna could have went . One of the them suggests that they go one way and the others follow . The stone lifts up as Luna and a spirit emerge from the ground . The spirit observes and says that the monkeys are gone . Luna thanks the spirit for helping her and the spirit puts the stone back in place . He calls Luna " little miss " and says he bets that she came from another world . Luna is a bit confused . The spirit sighs " good grief , a little kid wandering into the spirit world all alone , of all things " , and asks who knows what could have happened had he not been around . Angry , Luna asks him if that ' s any way to speak to someone older , and tells him he ' s still just a kid . To Luna ' s surprise , the spirit claims that despite his appearance he is actually quite old . He tells Luna that his name is Torunka and that it is nice to meet her . Monkeys walk around , while Luna and Torunka hide in a house . Luna asks if Torunka and the others are all Spellcaster spirits . Torunka replies that she is correct and all the other spirits have been captured . He explains that some of them have managed to give the monkeys the slip , but the Minus Curse turned them all into kids . He thinks that their powerful Minus energy has even made time flow in the opposite way . Luna asks what he means , and if he could be more specific . Flashback . As the flashback occurs , Torunka explains that the spirit world use to be a place where the spirits lived at peace with one another . He also explains that everyone would use their own abilities and work together to live good lives in harmony ( the spirits are shown to be working , and having a great time ) . Torunka then says however , that one day , ever since those monkeys appeared in the town of Schwank , everything changed ( as he says this , the sky get ' s red , and a darkness takes on a mysterious form ) . From what he had heard , they were trying to Minusize any and all things in the world . Torunka explains that when they switch their Cursed Needles to minus , the Minus Curse get ' s cast and any spirit get ' s captured by it ( as Torunka explains this , a staff turns slightly and shoots a dark aura which the spirits try to run from , but are shown to shortly be captured into the tablets ) . Present in the spirit world . Luna then asks Torunka if he knows a spirit by the name of Regulus . Torunka asks how she knows Regulus . Luna explains that she came to this world in order to rescue Ancient Fairy Dragon . He then wonders if Luna may be a Signer . Luna realizes he knows , and asks where she can go see Regulus . Torunka however says no , and that It ' s too dangerious to go see him now . He explains that Regules has been acting quite oddly lately . He further explains that it has gotten to the point that Regulus will appear , bearing his fangs at anyone who comes near him , or perhaps the thought that he was unable to absolutely protect Ancient Fairy dragon , has thrown his mind into disarray ( as he says this , a white lion is shown walking and growling , but not fully revealed , and who ' s eyes are white ) . Luna says , but without Regulus , Ancient Fairy dragon can ' t be saved . Luna also says they have to save Kuribon , and everyone else who was captured . she then re - asks him to please tell her where Regulus is . He answers her and says he conceals himself in the forest of Pojar . Luna then tells Torunka to lead her there . Torunka thinks that ' s crazy talk , and that they will get caught if they go outside . Luna however get ' s up , and leaves , shortly followed by Torunka . As he tries to catch up to her , she tells him to hurry up , which he tells her to quit picking on the nice old man . As they run , one of the monkeys spot them , and signals the others saying he found them . As Luna and Torunka keep running , Luna turns her head slightly and says they have been spotted , which Torunka says he told her so . As they keep running Luna says to wait as she stops . She then lays a bunch of glass bottles on the ground . Torunka tells her this is no time to be playing around . Luna then turns a clock part on a minus staff next to her . The glass bottles then roll towards the monkeys , and cause them to lose their balance and start tumbling away . Luna says this is their chance , and for them to hurry , which they then run . They ' re then shown to be walking on a mountain . Luna says that it seems like they ' re not coming after them anymore . Torunka however says that he dares not walk anymore , and lowers himself on the ground , tired . Luna says he ' s a boy , and to suck it up . Torunka however says that he is really an old man , and says he ' s not lifting one finger from this spot . After Luna tells him to suit himself , she lowers herslf , and puts her hand behind him , telling him he can piggyback . Torunka thanks her , and get ' s on . Luna then asks if the forest of Pojar is in the direction she is currently facing , to which he says yes . Torunka says to Luna that such a strong child she is . Luna however says she ' s not strong , and that she was always sick as a kid . Torunka though says that he can feel this heroic kind of strength from her . Luna however says that ' s not hers , and that he must be feeling the power of the person who ' s been protecting her for a long time . Torunka thinks It ' s Ancient Fairy dragon . Luna shakes her head , and says It ' s someone more close to her , someone who is always by her side . Back in the real world with Leo . Leo begins his turn and draws " Morphtronic Celfon " in Attack Mode . Using its " Dial On " effect , " Celfon " stops on a 3 and lets Leo Special Summon " Morphtronic Remoten " . Devack get ' s amused and says " Oh , a tuner huh ? " . Leo then uses " Level Mirroring " to change the Level of " Morphtronic Magnen " to that of " Magician Ape " . Leo ' s 3 monsters ' Levels now add up to 7 . He tunes the 3 monsters to Synchro Summon " Power Tool Dragon " . As they tune , Leo chants " Docking strength with courage in order to protect world peace ! Syncro Summon ! The envey of love and justice , Power Tool Dragon ! " Trudge is glad to see Leo get a Synchro Monster out before his opponent , while Yusei is pleased to see how Leo ' s dueling while carefully looking at his opponets field , and says Leo has matured . Devack laughs and calls " Power Tool Dragon " a toy dragon , which suits a non - Signer , like Leo . Leo tells Devack not to make a fool of him and uses " Power Tool Dragon ' s " effect to equip itself with " Break ! Draw ! " . Using the " Crafty Break " attack , " Power Tool Dragon " attacks and destroys " Magician Ape " . Devack ' s Life Points drop to 2500 and Leo draws a card from " Break ! Draw ! " . Leo ends his turn , telling Devack not to look down on him for not being a Signer , because he has the mightiest of all dragons on his side , and then says Power Tool Dragon ' s name ( after Leo says this , Power Tool Dragon roars as It ' s eyes become even more red ) . ( In the dub version Leo says " What ' s the matter ? Dragon got your toungue ? " ) . Back in the spirit world . As Luna is walking and carrying Torunka , she asks him where the captured spirits are taken . He answers her and says that he suspects after being Minumized , they ' re all herded into Zeman the Ape King ' s castle . Luna asks if Zeman is the leader . Torunka says yes , and then says that nobody knows exactly where he came from , or what his true goals are . Luna than mutters Zeman ' s name . A carving of the stone Ancient Fairy Dragon is sealed in is shown . A voice calls out " May those sealed powers be Minumized and come to me ! " . A staff is then shown and the clock part slightly turns . Right after , a lightning bolt shoots out of the sky and strikes the staff , making it disappear . Zeman ' s layer . A dark aura surrounds the staff Zeman is holding , causing it to vanish . Zeman get ' s mad and curses , saying that in order to completely turn Ancient Fairy Dragon into Minus , Regulus ' s presence will indeed be essential . The screen then pans over to all of the spirits that are in the tablets on the wall , and can be heard scared ( in the dub , the spirits are not heard at all during this part ) . Back with Leo ' s duel . Devack laughs at the idea of a minor duelist such as Leo doing so well in a battle determined by fate . Leo is displeased at being called minor and reminds Devack that he is risking his life and fighting . Devack announces that he shall offer this Duel to his God . He Summons " Dark Tuner Dark Ape " . Leo and his spectators start to worry over the possible appearance of a Dark Synchro Monster . ( In the dub , Trudge , remarks that it ' s powerless , to which Yusei replies " Not for long . " ) Devack then uses " Dark Wave " to reverse the Level of " Fighter Ape " Level to - 5 . The Level of " Dark Tuner Dark Ape " is subtracted from " Fighter Ape " as Devack Dark Tunes his monsters . In the Japanese version , he chants " " The one chosen by darkness , I invite you to this world to become its ruler . Dark Synchro ! Show yourself , Demonic Monkey King Zeman ! " " . In the English version , he chants " " When the shadows are devoured by even darker shadows , the curtain pulls back and reveals a world without light ! Come forth , Zeman the Ape King ! " " as he Dark Synchro Summon s " Zeman the Ape King " . Leo says he doesn ' t fear a Dark Synchro Monster as he has " Power Tool Dragon " on his side . Devack draws a card from the effect of " Dark Tuner Dark Ape " . He activates the card , " Closed Forest " . Yusei begins to panic , since Devack now has a Field Card he can Summon an Earthbound Immortal . The field spell then produces a forest around them . Back in the spirit world . Luna and Torunka find themselves inside a dark part of the forest . Luna says this is the forest of Pojar , and that the fog has gotten thicker . Luna spots a leaf flying upwards on a tree , and notes that even there , things are moving negatively . Torunka tells her it is best to be on her guard , because as he said , Regulus has lost his composure . Luna calls Regulus ' s name , and says they need to talk . Torunka panics and runs in front of Luna , and tries to get her to be quiet , asking if she has any idea what will happen if they get attacked . Luna says not to worry , and that once they talk to him he ' ll understand . Luna then calls Regulus ' s name again , and says they ' re not his enemy . After saying this , a large white armored horned lion with a Cursed Needle attached to its leg jumps out in front of them . Torunka recognizes this being as Regulus . Luna asks if this is Regulus . ( In the dub , when Luna calls for Regulus , she says " Here , kitty , kitty . " and that she ' s got a snack for him . When Regulus appears , Luna says in fear that she and Torunka might be the " snack " . ) Featured Duel : Leo vs . Devack .

He then activates the effect of " Magician Ape " to discard " Fighter Ape " and take control of " Morphtronic Magnen Bar " .

Devack then Tribute s " Morphtronic Magnen Bar " in order to Tribute Summon " Fighter Ape " ( 1900 / 1200 ) in Attack Position .
