The Imprisoned Ancient Fairy Dragon " in the Japanese version , is the fiftieth episode of the " Yu - Gi - Oh ! 5D ' s " anime . It first aired in Japan on March 18 , 2009 and in the United States on August 27 , 2009 . Summary . Battling Zeman . Yusei and Trudge are watching . Devack ' s Life Points are shown to be at 2500 , while Leo ' s are at 2000 . Leo begins his turn and uses the effect of " Power Tool Dragon " to add a random Equip Spell Card to his hand . Leo hopes very much that it will be a card that can beat " Zeman the Ape King this time . As he draws he closes his eyes , and after opening them he is happy , because he drew " Double Tool C & D " . In the spirit world . Inside Zeman ' s castle , while looking at the pit / screen , Luna thinks to herself , that she will rescue Ancient Fairy Dragon . Zeman then says " Magician " ( because Luna is disguised ) and asks that if he unseals Ancient Fairy Dragon right here and now , and Minumize both it and Regulus , Its powers will be his . Luna says that is correct . Zeman says he understands , but if what she is saying is lies , then she shall pay dearly . Torunka tells him " But It ' s true , and it will make Ancient Fairy Dragon all yours . " Zeman hmphs and lifts up his staff , pointing it at the pit / screen and says " Cursed Needle , release Ancient Fairy Dragon ! " . A Needle suddenly appears on the pit / screen , and after a second , the screen pans over to the area where Ancient Fairy Dragon is sealed . As this happens , The Needle floating above the crag turns its clock upwards , producing a purple / dark aura on Ancient Fairy Dragons crag , and making Ancient Fairy Dragon regain its color and shape . As Luna and Torunka look , Torunka says yes , just like that Zeman - sama . Luna stays silent as she watches Ancient Fairy Dragon ' s face get back its color . Zeman then asks the monkeys what they ' re doing , and to bring him Regulus , which they immediately obey . They go over to Regulus ' s cage and open it . Luna chants " O power to control all spirits , come to rest in my hand , Regulus come forward ! " . Regulus instantly get ' s up and walks out of the cage , while having an emotionless look . However this is an act as Regulus thinks to himself , that he will use these fangs to break those deplorable chains . Torunka says while dancing a bit excitedly , incredible , now Ancient Fairy Dragon is all Zeman - sama ' s . Torunka suddenly loses his balance and bumps into Luna , causing them to fall . After getting up , the Minus staff Torunka is holding switches its clock sideways . This causes Torunka to say that Zeman sure is an idiot , and that they ' ve got him totally suckered . He gets a scared look on his face when he realizes what he just said . Zeman asks what was that he said , while Luna looks at Torunka and says his name in a slight panic tone . Torunka goes on to say , they ' re there to rescue Ancient Fairy Dragon , and Zeman hasn ' t caught on to it , and finishes calling him a nitwit . One of the monkeys asks Torunka why he has the same staff they do . Luna starts to get up , asking Torunka why he said that , but as she does , she loses her balance and bumps into Torunka , which knocks off their hats . One of the monkeys says Luna is the girl that was in the town of Schwank , while another says she ' s no Magician . Torunka says they ' re busted , while Luna says they were so close . Zeman get ' s mad and curses , and then says so they were deceiving him all along , and to seize them . The monkeys immediately obey and run towards Luna and Torunka . Regulus instantly jumps in and saves them . For a few seconds they run from the monkeys , while on Regulus ' s back . The monkeys say to capture them , while Zeman says he will never hand them Ancient Fairy Dragon . He points his staff at the pit / screen , and the Cursed Needle above Ancient Fairy Dragons crag turns sideways while a dark aura surrounds it , Minumizing Ancient Fairy Dragon again who turns back how she was before . Luna who was watching , while on Regulus ' s back is saddened to see Ancient Fairy Dragon being Minumized again . Torunka says what a horrible mess because he goofed up . Regulus tells Luna to give him the staff . Luna asks if he has a plan . Regulus tells Luna that he is going to combine two Minuses to change it into Plus Energy , just like when Luna lifted the curse on him . Luna and Torunka are worried if he does that , there will be another huge explosion . Regulus however says hurry , otherwise Ancient Fairy Dragon will be sealed up entirely . Luna nods . Regulus takes the Minus staff , and bumps it against the cage he was in ( as he does , he narrows the bars so that the monkeys can ' t get in it ) , telling Torunka and Luna to stay in there , and then heads for Zeman . Two monkeys get near the cage with one of them telling them to open up , while another says they will turn them into Minus . Luna and Torunka back away a bit , while Luna says Regulus can do this . Back in the real world with Leo . Leo switches Power Tool Dragon into Attack Mode , which it has 2000 ATK ( weakened because of " Roaring Earth " ) . Leo then looks at Power Tool Dragon , telling it for them to throw their very best at him ( The eyes of " Power Tool Dragon " turn very red after Leo says this ) . Leo equips " Double Tool C & D " to Power Tool Dragon , increasing its ATK by 1000 , bringing it up to 3000 . Devack says " So ? You just lined up its ATK with Zeman the Ape King ' s . " , and finishes saying " In the eyes of a non - Signer such as yourself , that bit of nothing is the very best you have ? " . Leo spins his arm telling him to just keep blowing smoke , and stops spinning it as he commands " Power Tool Dragon " to attack " Zeman " ( Power Tool Dragon heads for Zeman after Leo says this ) . Back in the spirit world in Zeman ' s lair . Regulus is jumping towards Zeman . Zeman holds out his staff , as his and Regulus ' s collide , producing a small white flash . A dark / purple aura surrounds Zeman as he tells Regulus to stay out of his way , while Regulus also has a dark aura around him . Both Torunka and Luna say Regulus ' s name worried . As the struggle goes on , Regulus looks at the crag Ancient Fairy dragon is sealed in , in the pit / screen , and asks Ancient Fairy Dragon to please come back to him . Regulus then gets out of the struggle and jumps back at Zeman . Back in the real world with Leo . Power Tool Dragon is heading for Zeman . Devack says Leo ' s settling for a draw , but then says no in slight shock as he realizes something . Leo says that ' s right , and that Power Tool Dragon won ' t be destroyed , as long as it is equiped with an equip spell . Two white barriers form in front of Leo ' s monster as it collides with Zeman ' s staff . Back in the spirit world with Regulus . Regulus ' s Cursed Needle staff collides again with Zeman ' s , but this time a big flash occurs , which destroys all of the monkeys , and produces fire . As the fire heads towards Luna and Torunka , Luna ' s birthmark glows and a red barrier protects them both . Zeman says don ' t think this is over , and that as soon as he is defeated , the Minus Curse will be sent to Devack . Luna gasps having heard what Zeman said . Zeman is then destroyed . Back in the real world with Leo . Power Tool Dragon destroys Zeman , to which Leo yells excitedly , glad he beat Zeman . Leo then discards " Double Tool C & D " from Power Tool Dragon so it will go unharmed ( The ATK of " Power Tool Dragon " goes back down to 2000 ) . Trudge is glad , and says Leo finally beat that Dark Synchro Monster , but Yusei gets very alert when he realizes something . Devack begins to laugh . Leo asks what he ' s laughing about . Instead of answering , he reveals his face - down Trap Card , which is " Dark Matter " . ( In the dub , Devack answers that he ' s amused when somebody willingly walks into a trap . ) Devack explains when a Synchro Monster is destroyed , it sets two cards from the top of his deck , treating them as monsters . He then places two cards on his Monster Zone , both revealed to be " Fighter Ape " and " Magician Ape " . Leo equips Power Tool Dragon with the equip spell " Power Converter " and ends his turn . Devack silently laughs sinisterly . Back in the spirit world at Zeman ' s lair . The entire room is a mess . After a few seconds Luna calls Regulus ' s name . A " Dark Sage " says good grief , and that he managed to finally turn back to normal . Luna says he ' s , which the old man finishes saying yes It ' s him ( after he says this , an image of the younger Torunka can be seen on his face for a few seconds ) . Luna says Torunka ' s name , and asks if that ' s really him , and then says he surprised her that he really was an old man . This causes Torunka to laugh a bit . Regulus calls out Luna ' s name , to which Luna runs over to him saying his name , glad he ' s okay . Torunka asks if Regulus is okay , while Regulus says it seems that Zeman has been completely obliterated . Luna says really , and then asks where ' s Ancient Fairy Dragon then . Regulus says he doesn ' t see her anywhere , to which Luna says no way . Luna then looks at the tablets and thinks to herself saying the spirits haven ' t turned back to normal either , and that the curse is lifted so why . She then gasps in realization when she realizes Zeman said the curse was sent to Devack . Back in the real world with Leo and Devack . Devack smirks while beginning his turn and draws . Devack then says young boy ( Leo ) that he must thank him for defeating Zeman earlier . Angered Leo asks what he means . Devack answers saying because of him , he now has all the preparations to summon his Earthbound Immortal card set , and then holds up and shows Leo the card , while laughing maniacally . Yusei instantly recognizes what Devack showed Leo . Devack releases both of his set monsters ( the monsters fly up , and form a container ) . Leo begins to panic , but Devack tells him to not worry , because as the competitor he won ' t have his soul absorbed . ( In the dub , he says that his Earthbound Immortal requires a different kind of power source , which exists in the spirit world . ) Devack says he has more than enough sacrifices , and says " I sacrifice the spirits souls , descent forth Earthbound Immortal Cusillu ! " . Yusei turns to Trudge and says here it comes , but right after , the purple flames get very big and Yusei covers his eyes , while Trudge watches the purple flames , and Leo yells . Back in the Spirit world in Zeman ' s lair . A purple monkey geoglyph appears in the sky , which Luna notices . Suddenly purple orbs come out of the tablets and fly towards the geoglyph ( they ' re the spirits , and are in the same form as when humans get sacrificed to an Earthbound Immortal ) . Regulus says the spirits souls are , while Torunka wonders what the devil is about to transpire . Luna says the Earthbound Immortal is trying to awaken . Back in the real world with Leo . The screen shows a view of the on - ground monkey flame shape , as It ' s flames get bigger after a yellow lightning flash strikes at it . The spirits are shown flying out of the ground and up to the container , which is getting more and more purple with each spirit it absorbs . Once enough sacrifices are in the container , a purple beam of light shoots down from the geoglyph in the sky , and onto the ground ( there is also a hole in the part of the sky where the light descended ) . The ground then begins to shake , and shortly after , a giant yellow glowing dark monkey appears and let ' s out a small roar . Leo yells in fear . The screen pans away from the Immortal as dark lightning strikes around it ( it is also revealed to have 2800 ATK ) . Trudge says " The Earthbound Immortal ! " , and curses saying it finally showed up . Yusei says this is bad , and that the Earthbound Immortal is going in for a direct attack . Devack says his great god , Earthbound Immortal Cusillu cannot be attacked by the likes of Leo ' s monsters . He continues saying , in addition , it cannot be affected by any Spell or Trap card effect . Leo is shocked and says " No way ! " Devack says also , there are eight monsters in his graveyard , so " Closed Forest " will elevate the attack power of Earthbound Immortal Cusillu by 800 points . The monsters fly into " Earthbound Immortal Cusillu " , and its ATK goes up to 3600 . Devack says " May you curse your misfortune for ever intruding into this battle of the gods ! " . ( In the dub , it ' s " Perhaps next time , you ' ll think twice about taking your sister ' s place in a Shadow Duel " ! ) Devack then announces for his Earthbound Immortal to attack Leo directly . The Earthbound Immortal lifts up its fist , and prepares to attack . Yusei get ' s worried saying if that attack connects , Leo ' s finished , while Trudge yells Leo ' s name in worry . Leo however says " Finished nothing ! " , and sends " Power Converter " equipped to " Power Tool Dragon " , to the graveyard which will allow Leo to regain Life Points equal to the ATK of " Power Tool Dragon " . Leo ' s Life Points go from 2000 to 4000 . Leo finishes by explaining the ATK of " Power Tool Dragon " will become 0 for this turn . The Earthbound Immortal pounds its fist towards Leo as he runs . The Earthbound Immortal hits the ground , and the force causes Leo to get hit by debris and is knocked on the ground , while trying to get up . His Life Points go from 4000 to 400 as the smoke clears . Leo mutters while feeling weak " I - I can ' t lose , If I ' m finished off here , Luna will . . . Luna will . " Back in the spirit world . Luna mutters Leo ' s name , sensing and hearing what he said . She turns to Regulus and Torunka sayng Leo is in danger . Torunka asks what she means , but before she can answer , a white light envelopes them for a second , and afterwards they fly up into the sky . Torunka says they ' re going to get sucked into the geoglyph , while Regulus says at this rate the spirit world will be confined to eternal darkness . Torunka then says to leave this to him , which Luna says his name . Torunka says he shall use the last of his power to send Luna back to her own world , and says It ' s up to her , and to beat the Earthbound Immortal . Regulus agrees , and says the spirit worlds future rests in her hands . After Luna says their name one last time , Torunka uses his staff to produce a white flash , which envelopes Luna ( she is then teleported to the real world ) . Back in the real world . A red orb comes down , which surprises Devack . Trudge asks what is it . The light clears revealing Luna , whose name is said by Yusei . After opening her eyes , she looks at the beaten form of Leo . Luna instantly keels down to him deeply worried , and asks him to say something , while saying his name twice . Leo lifts up his head a bit says she came back , while she lifts him up . Luna asks / says he fought getting hurt this badly , even though faced against a Dark Signer . Leo says in a weak tone that he wanted to beat that guy ( Devack ) before she came back , and says he knew he couldn ' t play the hero ( after saying this his eyes begin to water ) . Luna however yells / screams that ' s not true , causing him to look up at her , whose eyes are also filled with many tears . Luna says " Leo , you . . . in my eyes you ' re . . . the best a hero could get ! " ( In the dub version , Luna said " Except be my hero . It ' s true , not . . . not as a duelist . . . but as my brother ! " ) . As she says this she hugs him as the tears quickly begin falling off her face . Leo is silent , and after a few seconds he closes his eyes and begins to sob as he let ' s the tears out as well ( In the dub version Leo says while she is hugging him " Not so hard , you ' re squeezing the tears out " ) . As Yusei watches silently , Devack says that the gang ' s all here . Devack continues saying Luna will fall prey to his Earthbound Immortal , and finishes by calling her young Signer . Luna says so he was the one commanding Zeman to collect all those spirits souls is he . Luna continues , saying she will never forgive him , for hurting the spirits , and for hurting the one person she holds most dear . Luna grabs Leo ' s Duel Disk . While unattaching it from him , Luna tells Leo she is dueling in his place . Leo says / asks what is she saying , he told her he ' d protect her didn ' t he , and finishes saying he should be the one to fight . Luna takes off his disk and puts it on her arm , and says to not worry , he did his best just for her , now she will do her best just as hard as him . Leo however tells her to stop , and that if she fights Devack even she will . Luna smiles at him , and softly says she ' ll be fine , and not to worry . After getting up , Luna looks at Yusei who says her name , and then notices his mark is glowing , while Luna notices hers . Simalerly Mina points out Akiza ' s mark is glowing . Meanwhile Jack , who is riding on his Duel Runner says while looking at his mark " A Signer ' s battle is finally underway huh ? " . Luna says she won ' t lose , because she has Leo and everyone else by her side . Luna looks at Power Tool Dragon , who lowers itself down to her , while Luna tells it to hang in there ( Power Tool Dragon looks at her slightly as its eyes get very red ) . Luna then turns to Devack . Devack remarks that even Life Points on the same level as cinders will be ample tribute to his god . Devack continues by saying " Allow me to show my respects to you , young Signer , by summoning a very special spirit . " Devack activates the continues Trap card " Cursed Prison " . Devack explains that it will special summon one Synchro Monster onto his field , ignoring It ' s summoning condition in defense mode ( after saying this he holds up the card , making Luna gasp ) . Devack says " Appear now , my prisoner , Ancient Fairy Dragon ! " . The Trap Card then turns white as a cage comes out of it , which is revealed to be " Ancient Fairy Dragon " inside it . Luna says the name of " Ancient Fairy Dragon " worriedly , while Devack ends his turn . Devack asks Luna how does it feel to face the very same dragon she is linked to by the bonds of fate , as an enemy . Luna thinks to herself saying for Ancient Fairy Dragon to hold on , as her and Leo are going to rescue her . Luna begins her turn and draws Limiter Removal " . Luna activates the effect of " Power Tool Dragon " , which will add a random equip spell to her hand . After drawing the card , Luna plays it , equipping Power Tool Dragon with the equip spell card " Central Shield " . Leo explains Central Shield is the ultimate shield that reduces all attack damage other than towards the equipped monster to 0 , wether Devack ' s Earthbound Immortal is affected by spells or Traps , and finishes telling Luna good job . Luna nods , then thinks to herself that this shield will protect her , along with Leo ' s hopes . Luna then sets both " Respect Syncron " and " Limiter Removal " face - down in her Spell / Trap card zone , ending her turn . Devack remarks to Luna , it seems she cannot attack " Ancient Fairy Dragon " after all . Devack continues saying but his Earthbound Immortal isn ' t limited to just attacking directly , and finishes saying " very well , as you wish I shall crush that toy dragon of yours ! " . Devack begins his turn and draws . He commands Earthbound Immortal Cusillu to attack Power Tool Dragon . The Earthbound Immortal brings its fist towards Power Tool Dragon . Luna however reveals the Quick - Play Spell Card " Limiter Removal " . Luna explains it doubles the attack points of all Machine monsters on her field , shocking Devack . The ATK of " Power Tool Dragon " goes from 2000 to 4000 . The Earthbound Immortals fist collides with Power Tool Dragon , which creates a big explosion , and shakes the entire area , while Leo and Luna cover their eyes . After the explosion begins to clear , Trudge says they did it . Devack curses and calls Leo and Luna fools who dare to defy such god - like power , as his Life Points go from 2500 to 2100 . He continues saying his Earthbound Immortal shall not falter , and by sacrificing a monster on his field , his Earthbound Immortal will avoid destruction and halve Luna ' s Life Points . Devack reveals that was why he summoned Ancient Fairy dragon . He releases Ancient Fairy Dragon , and a dark circle surrounds Luna hurting her , as her Life Points drop from 400 to 200 . Luna weakly begins to fall , but Leo yells her name catching her , asking if she ' s okay . Luna says she ' s fine , and now the real fight can get started . Devack Wonders what she means by that . Luna reveals that she knew Devack was going to send Ancient Fairy Dragon to the graveyard from the start . She continues saying now Devack is giving her back , her dear friend . Luna activates the face - down continues Trap Card " Respect Synchron " . She explains that when a Synchro monster is sent to the Graveyard through an opponent ' s card effect , this can ignore summoning conditions and special summon it to her field , shocking Devack visibly . A light appears below Leo and Luna . As the monster surfaces , Regulus appears saying Ancient Fairy Dragon ' s name , and breaks the chains binding her , with his fangs and then vanishes . ( In the dub , he says nothing . ) Ancient Fairy Dragon ' s wings unfold as her eyes turn more yellow , and she lifts her head upward and Roars ( as she does so , her ATK is revealed to be 2100 ) . Leo is amazed by the dragon , and tells Luna she did it , which she nods , and they both look up at Ancient Fairy Dragon . Luna says to Ancient Fairy Dragon that they finally get to meet . Ancient Fairy Dragon lowers itself slightly and says " Luna , I thank you from the bottom of my heart for keeping the promise you made on that day so long ago , thank you so much . " Trudge walks a bit closer and says / asks " So that ' s Ancient Fairy Dragon . " , to which Yusei agreed . Trudge remarks saying that ' s something else I tell you . Yusei however says the match isn ' t over yet . Luna sends Central Shield to the Graveyard to negate the effect of " Limiter Removal " that would destroy " Power Tool Dragon " . Devack remarks " Stupendous , a real Signer is altogether different ! " Devack ends his turn and says " Now , show me a real duel elected by the gods ! " Luna tells Leo to let ' s go , which he says yes . Leo says It ' s their turn , and they both draw " Rocket Pilder " . Luna next explains Ancient Fairy Dragon ' s effect ; by destroying a Field Spell , she regains 1000 Life Points . Devack is surprised by her saying " Field Spell " . Closed Forest is destroyed , along with the forest around them . Leo excitedly says alright , while Luna ' s Life points go from 200 to 1200 . Devacks Earthbound Immortal loses the extra ATK it gained from Closed Forests effect , bringing it back down to 2800 . Yusei points out that an Earthbound Immortal ' s effect is negated if there is no Field Spell Card on the field . Trudge remarks Luna did a good job . Luna explains that the effect of " Power Tool Dragon " will activate , adding one random equip spell to her hand ( the card she reveals is " Pain to Power " ) . Luna then equips " Rocket Pilder " to " Power Tool Dragon " , and equips " Pain to Power " to " Ancient Fairy Dragon " . Luna commands Power Tool Dragon to attack " Earthbound Immortal Cusillu " . Devack is a bit confused saying she is attacking with Power Tool Dragon , the one with lower Attack power . The rocket attached to Power Tool Dragon fires , causing it to fly up towards " Earthbound Immortal Cusilu " ( as it does so , Power Tool Dragon is surrounded by a yellow fire from the rocket ) . The Earthbound Immortal tries to hit Power Tool Dragon , but Power Tool Dragon evades it , hitting the Immortal in the stomach . This causes a massive explosion , and Leo shields Luna from the force of it , as her Life Points go from 1200 to 400 . As the smoke begins to clear , Devack says It ' s just as he thought , and says they chose to receive gods punishment did they . Leo tells Devack don ' t count on it . Luna says since " Power Tool Dragon " is equipped with " Rocket Pilder " , it won ' t be destroyed , and continues saying it will decrease the ATK of " Earthbound Immortal Cusillu " by " Power Tool Dragon " . Devack ' s Earthbound Immortal goes from 2800 ATK to 800 , shocking him ( there is also a visible hole in the Earthbound Immortals stomach where Power Tool Dragon attacked ) . Luna further explains that since Ancient Fairy Dragon is equipped with " Pain to Power " , Its ATK will increase equal to the damage she took from Power Tool Dragons attack . Ancient fairy Dragons Attack points go from 2100 to 2900 , and it let ' s out a roar . Luna says turn her pain into power , and commands Ancient Fairy Dragon to attack Earthbound Immortal Cusillu . Ancient Fairy Dragon slowly flies up as Luna says " ETERNAL SUNSHINE ! " . Ancient Fairy Dragon wings produce a rainbow blinding light , that causes everyone to cover their eyes except Luna .
