Power Tool Dragon " in the Japanese version , is the thirty - sixth episode of the " Yu - Gi - Oh ! 5D ' s " anime . It first aired in Japan on December 3 , 2008 and in the United States on December 6 , 2008 ; Yusei is taken by Crow to Martha ' s refuge to treat his injuries from his Duel with Kalin . Meanwhile , Leo insists that the Signers should all collaborate to fight against the Dark Signers and suggests they contact Arcadia Movement in seek of Akiza ' s co - operation . Summary . Infirmary . At night time , Yusei ' s friends wait outside the infirmary . His Duel Runner , mangled from his encounter with Kalin , is tied together outside . Rally , still wrapped in a blanket after discarding his clothes earlier , clutches Yusei ' s worn out helmet , hoping he ' s okay . Yusei struggles with the pain as Dr . Schmitt removes another slice of the shard from Yusei ' s wound . The door to the waiting room opens , as Schmitt and Martha emerge . They say that Yusei will be fine once his wounds seal up . Nervin , Tank and Blitz , also clad in blankets after their last shenanigan , signal their relief while Crow shouts out and begins celebrating . Rally interrupts his performance , letting out a sneeze , quickly followed by the other three blanket - clad boys dropping to the floor shivering . All of them are after catching a cold from running without clothes when they brought in Yusei ' s Duel Runner . Tops . Tanner and Yanagi are shown to Leo and Luna ' s house at Tops . Tanner checks for confirmation that their parents are away . Luna assures them that their parents are always away and Leo informs them that they have plenty of spare rooms . As Luna sits down , Leo calls Tanner aside and whispers how Luna is frail , so she can ' t go out much . He could never leave her alone , so both of them end up inside , which gets boring , he tells Tanner . Yanagi calls Tanner out to the balcony - style rooftop , from which he can see the whole city . Tanner sees this as an opportunity to pick up a signal from Satellite . As Tanner rummages for a notebook computer , Leo ponders on Luna ' s prediction ; If it ' s right , it would mean that Yusei has already started battling with the Dark Signers . The prediction is too unsound for Tanner to make such a call and he decides that they must wait for a call from Satellite . They wonder if Yusei has won . Tanner is unsure , but states that Yusei is not one to give in easily . Leo agrees , gets excited , and starts wondering if he may be able to help somehow . The group begin talking about Luna ' s dream , where the Crimson Dragon and its five associates battled the Earthbound Immortals . Yanagi believes the dream may have been an ancient battle . Leo rips out his Deck and flips over the card , " Power Tool Dragon " . He asks Luna if it was involved the battle . This sparks a reaction from Luna , as the dragon seems to resemble one from the dream . She tries to dismiss the information as not being overly important . Leo is unconvinced and believes himself to be holding one of the Signer Dragons and that he might be the fifth Signer . Leo starts dancing and singing in anticipation of a Mark of the Dragon appearing on him . Tanner and Yanagi slip over to Luna to ask if its true . She points out that Leo ' s dragon is robotic and that this was an ancient battle . As they glance over at Leo celebrating , Luna says that she said it to cheer him up . Convinced that he ' s the fifth Signer , Leo appoints himself in charge of protecting Luna . Yanagi and Tanner pause before giving him a forced cheer of encouragement . Later , the gang continue to discuss the Signers . Since all the dragons fought on the same side , Leo deduces that all the Signers must be on the same side . It makes sense to Yanagi and he begins listing the names of the Signers . Leo promptly reminds Yanagi to list " his " name . Tanner is unsure if Akiza Izinski is on their side , as it would mean the Arcadia Movement would also be on their side . The twins are unfamiliar with this organization . From the rumors Tanner has heard , they ' re a nefarious organization that gathers psychic duelists to carry out suspicious experiments . Psychic duelist is another term new to the twins . Yanagi takes the liberty of explaining how duelists with such psychic powers rarely come into the world , from what he has heard . Luna asks why Akiza is there . Tanner is unsure , but assumes she may have her own reasons for being there . Leo suggests that they try asking " Big - Sis Aki " to co - operate with them . He quickly tosses any concerns Tanner laid out aside , dismissing them all as no more than rumors . As Leo sees it , they have no reason to distrust these people . Yanagi and Tanner consider his theory . He accuses himself and Tanner of being too distrusting , like adults . Tanner sees no harm in simply discussing information with them . He takes out Blister ' s notebook computer to see if he has a means of communicating with the movement on it . Akiza ' s weakening . While practicing dueling , Akiza has " Black Rose Dragon " tear down an opposing " The Fiend Megacyber " hologram and subsequently strike the test dummy opponent , which is smacked onto the floor . Akiza is left panting for a few seconds , before stopping to smile in pride of her destruction . Sayer watches nearby , but is slightly unsure . A colleague approaches him and notes a continuous decline in the lady ' s powers . In Akiza ' s case , her powers are directly linked to the violent nature of her mind . Sayer is aware , but maintaining her vengeful energy has proven to be a bigger issue than they had predicted . Sayer ' s colleague says there has been a change in Akiza ' s mind . Sayer claims to know the reason as he flashes back to Yusei talking to her during the Fortune Cup Duel . Sayer meets up with Akiza to ask if everything is alright . Akiza claims not to be feeling so well . Sayer encourages her to tell him if there ' s something on her mind ; There ' s no need to hide it , as they ' re are all friends . She says there is nothing on her mind . Sayer talks about how psychic duelists have been discriminated against , and that it was for this reason he set up the Arcadia Movement . He goes on to say that he can help if there is something bothering her and that only he can stop the rage nested in her . Akiza says she understands and walks past him . Sayer then calls after her , saying that Yusei can ' t save her . Akiza is shocked . Sayer continues , saying that he is the one who saved her , he was the one who gave her a home when she had nowhere else to turn , and that she shouldn ' t forget that she owes him . After Akiza has departed , Sayer ' s phone begins to ring . He is informed that a man named Tanner wants to speak with him . Sayer immediately recognizes Tanner as the former pro - duelist . Akiza exits to a balcony , where she reflects on her Duel with Yusei and wonders why she is reminded of him . Martha ' s talk . Yusei wakes , unaware of where he is , after suffering nightmares of his Duel with Kalin in which Kalin ' s monster , " Earthbound Immortal Ccapac Apu " , nearly killed him . Martha comes in and tells him that Crow brought him here . One more flashback and Yusei remembers that he had been fighting Kalin . Martha briefs him on a few current events ; The doctor pronounces Yusei ' s escaping with minor injuries a miracle , Rally and the others managed to haul his Duel Runner over , catching colds in the process , and that Crow disappeared in a hurry . Martha damns the Runner , as she calls Yusei and his friends " ungrateful children " ; once Yusei started talking like an adult , he forgot all about them , his foster parents , and obsessed over building the Duel Runner and , in the end , went off to a dangerous place . Martha says she ' s lost her words and asks why he went there . Yusei replies that people had been disappearing from Satellite and he was investigating . Martha feels that this is too much for Yusei to handle by himself . She reminds him how he grew up with Crow and Jack , who were like brothers to him and suggests that he ask them for help . She also reminds him of a philosophy he used to preach back when he lived here about " believing in your friends " . There comes a time in every man ' s life , where he feels he must do something reckless . Believing Yusei to have entered such a phase , she again reminds him that his friends are sure to help . She slips Yusei two apple slices , and he thanks her for her help . Martha doesn ' t let him off easily , threatening to " beat his butt down " if he leaves before his wounds heal up . Dinner at the Arcadia Movement . Inside the Arcadia Movement building , five well dressed figures sit at a table . Sayer is located at the head of the table , with Yanagi and Tanner on the side to his left . The twins sit across from them on Sayer ' s left . Yanagi checks with Tanner to see if he knows what order to use his cutlery in . Tanner reminds him that that ' s not their main priority ; Sayer is . After hearing the story of the Signers and Dark Signers from Leo , Sayer agrees to co - operate , much to Luna , Tanner and Yanagi ' s surprise . Sayer asks to be excused while he sends for Akiza . After Sayer leaves , Leo begins to celebrate over how well it went . Yanagi is surprised that it went so well . Tanner is unsure and believes that they shouldn ' t let their guards down . Leo writes them off as being skeptical grown - ups and wonders when they ' ll be getting their food . As Luna tries to calm him down , gas leaks in through a vent , causing the four to feel drowsy and fall asleep . Sayer and four uniformed members of the Movement , equipped with gas masks , enter the room . They stare at Luna , who sleeps sitting up , while the others have all collapsed onto the table . Sayer , referring to himself as Leo ' s uncle , says that he plans on making her a member . Leo ' s test . Tanner and Yanagi are dumped in a cell . Luna wakes up in a room with Akiza , who tells her to keep quiet and watch . Luna rises and makes her way to Akiza ' s side . Both of them stare through a full length window , where they see a Duel arena . Sayer stands at one end . At the other end , chained by his ankles and wearing a strange helmet device , stands Leo . Akiza says that it is a test . Sayer explains the set - up to Leo ; Luna has a mysterious power , which lets her speak to spirits . Being her twin brother , Leo may possess some sort of power , as well . He is about to test that . Leo deduces that Sayer had lied about helping them fight the Dark Signers and is disgusted by Sayer ' s actions . He spots Luna watching and yells at her to run . Sayer tells him that she can ' t hear him . Leo asks him what the Arcadia Movement is , to which Sayer replies that he feels if psychic duelists are trained enough , they will become fine soldiers . Using dueling , the Arcadia Movement amplifies their powers and , soon enough , his psychic duelists will put the world in motion . He sees this as their revenge against the world for the discrimination they have received . Leo wonders if Akiza is a part of this , but Sayer assures him that she is not yet aware . Sayer begins the test . He Normal Summon s " Krebons " and Set s a card . Leo begins his turn and Summons " Morphtronic Radion " , whose ATK rises to 1800 , due to its effect . He has it attack " Krebons " , with its " Earphone Shoot " attack , but Sayer uses the effect of " Krebons " , paying 800 Life Points to conjure a forcefield , negating the attack . Leo is shocked to see him drop his Life Points to keep his monster out . He furiously ends his turn . Sayer Summons " Psychic Snail " , frightening Leo with its high ATK . It attacks " Radion " with its " Snail Thunder " attack . Leo is injured by the attack . Sayer explains that Psychic dueling and the dueling Leo is used to are dimensions apart . Sayer then attacks Leo directly with " Krebons " , knocking Leo onto the floor and dropping his Life Points to 2700 . Luna worries for Leo and turns to Akiza , asking why they ' re being so cruel . Akiza restates that it is a test ; If Leo faces a dilemma , there ' s a chance his psychic powers could awaken . Leo begins crying in pain . Sayer frowns and tells Leo to get up . Now that Leo knows the Movement ' s secret , Sayer informs him , he has no guarantee over his life . He recommends that if Leo values his life , he should attack him like death itself was at his heels . One last yell at Leo to awaken his powers prompts a flashback , as Leo remembers himself promising to protect Luna . Vowing to protect Luna , Leo rises , ready to fight on . Sayer is glad to see this , noting that psychic duelists awaken their powers this way , by recognizing what they must protect . Leo begins his turn and Summons " Morphtronic Remoten " , followed by the Spell Card , " Junk Box " , allowing himself to Special Summon " Morphtronic Radion " . He tunes both monsters and chants " " Docking strength with courage to protect world peace . Synchro Summon ! Envoy of Love and Justice , Power Tool Dragon " " , as he Summons " Power Tool Dragon " . Sayer describes the Dragon as a somewhat promising card . " Power Tool Dragon ' s " effect allows Leo to add 1 random Equip Spell Card from his Deck to his hand . He gets " Double Tool C & D " , which he equips to " Power Tool Dragon " , raising its ATK to 3300 . Using the attack " Crafty Break " , " Power Tool Dragon " attacks " Krebons " . Sayer prepares to use its effect , to negate the attack , but Leo swings his arm around , stating that it won ' t work , due to " Double Tool C & D ' s " effect . " Krebons " is destroyed and Sayer ' s Life Points drop to 1100 . Convinced that he ' s the fifth Signer , Leo is certain he won ' t lose and that he ' ll rescue Luna . Luna whispers that he can do it , as she watches . Sayer plays " Psi - Station " . He then Summons " Psychic Commander " and uses the effect of " Psi - Station " , giving up 500 Life Points to boost its Level by 1 and increase its ATK by 300 . He then tunes it with " Psychic Snail " , chanting " " Surge , my black mist of vengeance . Synchro Summon ! Mental Sphere Demon " " to Synchro Summon " Thought Ruler Archfiend " . The demon rises behind Sayer from a black mist . Both twins are anxious , but Leo calms himself , remembering that he can use " Power Tool Dragon ' s " effect to negate its own destruction by sending an Equip Spell to the Graveyard . Sayer says he must applaud Leo for giving him such a hard time , but he doesn ' t seem to be the phenomenon that he ' s been looking for . Sayer activates his face - down " Battle Teleportation " , allowing " Thought Ruler Archfiend " to attack Leo directly , winning the Duel . Sayer regards this twin as just a " worthless drag " . Luna beats against the window , trying to call to Leo . Featured Duel : Sayer vs . Leo . Turn 1 : Sayer Sayer draws " Krebons " and subsequently Normal Summons it ( 1200 / 400 ) in Attack Position .
