Yu - Gi - Oh ! 5D ' s - Episode 080 " The Super Genius " , known as " The Mysterious Super Mechanic " in the Japanese version , is the eightieth episode of " Yu - Gi - Oh ! 5D ' s " . It first aired in Japan on October 14 , 2009 and in the United States on November 13 , 2010 . Mina and Trudge ask Yusei , Jack , and Crow to take care of an youth named Bruno . Summary . Yusei is riding on his Duel Runner saying " This kind of speed is no good ! " and then thinks back to Vizor ' s words which is " Surpass your limits , Yusei ! " . Yusei continues to think saying he needs a new engine that can surpass the limits no matter what . Later in the night , Yusei , Jack , and Crow are out to a fancy restaurant . Crow digs in , and then says thanks . He continues by saying he doesn ' t know what this about but ( he stops in mid sentence and tells / urges Yusei and Jack to eat ) . Jack though says this is strange while his arms are folded . After Mina and Trudge cough , Mina stutters asking what is it . Yusei says Martha always told him " Nothing in this world is free . Be thankful to those who speak strict words to you . Watch out for a person who talks too nicely " . Jack says It ' s just as Yusei says , and adds these people ( Trudge and Mina ) wouldn ' t treat them like this for no reason . Trudge and Mina get nervous as Trudge stutters / asks what is it , like Mina did . Jack then asks so there ' s no strings attached . After being hesitant , Trudge tells them " Truth is , I have a small favor to ask of you . " Jack says he knew it , Mina says It ' s nothing that ' s too difficult . She continues by saying they found a person with memory loss , and were wondering if they could take care of him . Yusei asks why should they do something like that . Mina says right now , New Domino City is busy with the tourists and Turbo Duelists , and finishes saying It ' s okay if just for a little while . Jack tells her their garage isn ' t a hotel . Crow adds while eating that they can ' t take care of anyone right now anyways . Trudge begs Yusei , and he refuses , while Mina begs Jack , but he also refuses . Trudge continues to beg saying can ' t they do something , and Crow intervenes saying he refuses . This gets Trudge mad and he says they ' re being treated to something like this , and they plan to refuse . This makes Crow think , and then asks where he is right now . Trudge remarks he should have been here a long time ago . Crow then tells him if he doesn ' t come , then they can ' t do anything . As they walk , Crow says that was close because they were about to take in a stranger . Jack However remarks saying that ' s because Crow eat all that food without paying attention to the details . Crow retorts saying that ' s because he never knows when he ' ll eat food like that again . They then spot a person working on Jacks Duel Runner Phoenix Whirlwind . Angered , Jack asks what he is doing to his Duel Runner . Jack continues by asking if he is one of those Duel Runner thieves , and then punches him in the face so hard that he flies to the ground ( this is shortened in the dub ) . Jack finishes by stating " Don ' t ever come near my Duel Runner again ! Be glad I ' m only doing this to you ! " . He then drives off , while Mina and Trudge ( who were about to get in their vehicle ) wonder what ' s wrong with Jack . Yusei grabs the person , asking if he ' s okay . Crow tells Yusei to just leave that guy alone , but Yusei does not agree . Trudge and Mina then run over asking what happened . Crow says it wasn ' t Jacks fault , and points at the person Yusei is next to saying It ' s because this guy messed with Jacks Duel Runner . After overcoming her shock , Mina angrily says the persons name ( which is Bruno ) , and then asks why is he in a place like this . Bruno gets on his knees apologizing , by saying he thought Jacks Duel Runner was amazing , and he got sucked up into it . Yusei asks if this could be the person Trudge and Mina wanted them to look after , to which Mina affirms . Crow turns to Yusei asking what they should do . Yusei starts by saying even if he asked him to ( he doesn ' t finish that sentence , because Jack shows up ) . Jack rides by them and grabs Bruno saying he ' ll return him later , before riding off . Crow wonders what ' s going , and Yusei says for them to go . After getting on their Duel Runners , Yusei tells Trudge and Mina to let them handle the rest . Bruno gets thrown to the ground , and then begs Jack to please stop , saying he hates violence . Crow asks Jack what ' s gotten into him all of a sudden . Jack ignores him , asking Bruno what he did to his Runner . Yusei wonders what he is talking about . Jack answers by saying his Runners power has increased , surprising Yusei . Bruno tells Jack all he did was adjust the computer in his Runner a bit . Crow is surprised , and says Yusei tried to increase the power of their Runners so much , and this guy ( Bruno ) did all of that in that short amount of time . Jack adds that ' s the only thing he can think of . Yusei puts his hands on Bruno ' s shoulders , kindly asking him to tell him how he did it . Bruno is then shown to be on a computer that has Jacks Runner on it . Bruno states he changed the timing of the boosters , so now it can power up slightly . Yusei admits he hadn ' t noticed it before . Crow wonders what they ' re talking about , and Jack replies saying he has no idea , and adds for Crow to not let his guard down . Jack finishes saying he can ' t think of him being an ally . Turning their attention back to Bruno and Yusei , Bruno says these also apply to Yusei and Crow ' s Duel Runners as well , and if he tweaks the program , the power should be greater then now . Crow surprised by this , asks really . Jack says his name , asking if he ' s listening to what he ' s saying . Bruno turns to Crow saying he ' ll adjust it right away , which Crow is thrilled . Jack face - palms , while Yusei asks if his name is ( Yusei doesn ' t finish his sentence because Bruno tells Yusei his name ) . Bruno then says Yusei and Crows names , and shortly finishes by saying Jacks ( indicating he knew their names ) . Yusei says with Bruno ' s skills , he wants him to look at this , and that It ' s not moving so well . The computer screen then changes , and Bruno says this is the Ener - D engine using the Yusei project . Crow asks if it still rotates , to which Yusei says it doesn ' t yet . Bruno states It ' s just using a program right now , and then says but It ' s better for them to use it . He continues by saying the Ener - D in a Duel Runner engine gets worn down as it is used , but they can use the program to improve the speed . Jack asks Yusei saying isn ' t that what the new engine was for , and if he ' s making a mistake . Yusei tells Jack to stay quiet for a while , as he and Bruno are talking about something important right now . Jack gets mad asking if Yusei wasn ' t serious when talking to him , but Yusei ignores him and continues to talk to Bruno . After Jack says Yusei ' s name once more , Crow walks over and tells him to leave it to Yusei , because they ' re talking about something important . After getting mad , Jack walks off saying Crow can do what he wants . Some time passes , and Crow says It ' s like Yusei is a fish that found water , and then yawns . The next day , Crow sleeps while Yusei and Bruno talk . Yusei thanks Bruno , and says his suggestions have been very helpful . Bruno though says Yusei ' s basics for it were solid , and finishes saying " As expected of Dr Fudo ' s son . " While getting some food and drink from a stool next to them , Yusei asks if he knew his father . Bruno doesn ' t answer and says Dr Fudo ' s Ener - D is in all the Duel Runner engines . Bruno continues saying any Duel Runner mechanic would know , and then asks if Yusei ' s name came from the Yusei gear . Yusei replies he thinks so . Bruno asks if that ' s true , and then say It ' s an interesting name , and then says the " Yusei gear " is an interesting name . He then says one gear won ' t do anything , and states the central gear uses the surrounded gears to rotate . Bruno continues saying if they were just using parts of the Duel Runner , what ' s the central gear that moves them ( this time he is referring to themselves ) . Yusei answers it is the Duel Monsters that are with them in Turbo Duels , and above that he has bonds with Jack and Crow . Bruno comments it sounds wonderful . Yusei then says Mina told him that he lost his memories . Bruno answers by saying when he realized it , he was washed up on the beach . Yusei asks if he was in some sort of accident , but Bruno says he doesn ' t remember it at all . Bruno states when he works on Duel Runners and Duels , it feels like he can remember something . Yusei understands , and asks if Bruno could stay for a while . Bruno asks if that ' s okay , to which Yusei says yes , for the WRGP they need a new machine . Bruno says if Yusei ' s okay with him , he ' ll become part of the gear that reaches towards Yusei ' s dreams . Yusei thanks Bruno and holds out his hand . Just as Bruno is about to shake his hand , he switches to his other one ( showing that he is left handed ) . A while later , Jack and Crow are then shown to be sitting on a couch near them , with bored / annoyed expressions on their face . Just then , Leo and Luna come up , as Leo asks Yusei to come play , and Luna adds Leo found a new combo . Seconds later , Akiza comes in saying Yusei ' s name , and says she has a problem with her physics . After Crow shushes them , Leo asks who that person ( Bruno ) is . Jack says he ' s a refuge entrusted to them by Sector Security . Crow adds in right now he ' s a super mechanic that ' s working with Yusei . Leo likes this , and asks if he could work on his Duel Board . Crow answers maybe ( in the dub Crow said no ) . As everyone turns their attention back to Yusei and Bruno , Luna comments It ' s strange , and wonders if there could be that much to talk about . Crow states now the amount that they ' ve talked to each other ( Yusei and Bruno ) has surpassed how much he ' s talked to Yusei . Leo comments " They ' re like two ducks side by side . " Luna however says that ' s only used for describing a man and a woman . Leo rubs his head saying is that so ( in the dub , Leo said Yusei was his best friend , and Luna argued asking who said Yusei was his best friend ) . Akiza then sighs annoyed , which Leo asks her what ' s wrong . Akiza turns saying she ' s going home , and that it looks like she ' s a bother if she ' s there . Leo asks if she by some chance is jealous . Akiza turns around saying " Stop talking about other peoples business , you ' re just children ! " and then leaves ( in the dub version she threatened Leo that she could squish him like a grape ) . Leo looks at Luna saying Akiza is really angry , and Luna looks at Jack asking is this really fine . Jack states like he would know that , and Leo agrees . Crow comments It ' ll be worth all the trouble if they can get one step closer to the completion of the new engine . Later on , Bruno is typing on the keyboard , as well as Yusei ( as they do , images of Yusei , Crow and Jacks Runners are on the screen , as well as the gear ) . More time passes , and Bruno says they did it , and finishes saying " This program is a miracle ! " , to which Yusei agrees . Bruno then asks to rest a bit since he hasn ' t had rest for two days ( three days in the dub version ) . Yusei agrees saying he hasn ' t ether , and finishes saying they ' ll install it ( the program they made ) into the machine tomorrow . They leave the Shack , turning off the lights as they do so . As they sleep , a mysterious figure goes over to their computer . The next day , Jack is angry because the data ( what Yusei and Bruno worked on ) is stolen . Yusei admits he was careless , and that he should have kept a backup . Bruno says both himself and Yusei were careless , and that there is nothing they can do about it . Jack grabs Bruno though , and asks if he was the culprit , and adds he thought Bruno was suspicious from the start . Bruno however tells Jack he is wrong , and that It ' s not him . Yusei then walks over telling Jack to let Bruno go . Jack though tells Yusei to not stop him because he ' ll get everything out of Bruno . Crow walks over telling Jack to stop it already , causing him to ask Crow if he ' s trying to protect him as well . Crow states there is nothing to protect , because if Bruno was the culprit , then he would have run away after stealing the data . He finishes by saying what kind of thief would stick around after stealing something . Jack agrees and let ' s Bruno go . Bruno then states creating a program needs lot ' s of work , and that It ' s complicated . He folds his arms saying It ' s near impossible to create it ( the program he and Yusei made ) . Jack concludes then that the only way is to find the thief . Crow blows on the computer keyboard saying the thief hadn ' t left behind any evidence , and finishes saying he can ' t even find a finger print . Jack then says without any evidence , how will they find the thief . Bruno realizes something , which prompts Yusei to ask what ' s wrong . Bruno walks over to the table where he got a cup ramen , and notes one of them have disappeared . Jack gets ticked off because one of the GoGo cup ramen is gone . Bruno walks over to the desk and gets out a Metal chop stick . Going over to the Trash can , he gets out a Piece of a Cup ramen pack . Examining it , he notices a finger print , and says he found the thief ' s print . Bruno concludes the thief ate cup ramen while stealing the data , surprising everyone . He continues saying the thief couldn ' t get the cover off , and he removed his gloves ( what Bruno picked up was the cover part ) . As Yusei and Bruno start typing on the computers , Jack asks Yusei if he ' s really doing this , to which Yusei replies yes , and says if they enter the fingerprint into the Security ' s database , they can find the thief . Jack however states that Security ' s database is protected by a strong firewall , and if they make a mistake in hacking they ' ll get caught . Yusei though says if they use all the world ' s servers to hack , they can get in within 5 minutes ( after saying this , the computer screen shows different parts of the world , and a red line is connecting them ) . Yusei asks Bruno if he can get in within 5 minutes , to which he says he should be able to . Yusei then asks Jack if they should stop . Jack folds his arms replying that he ' ll leave that decision to Yusei . Bruno tells Jack to not get angry if they fail , but Jack says of course he ' ll get mad . Bruno starts to hack in , and seconds later , Yusei states they ' re in . Yusei asks Bruno if he can get through , to which Bruno says yes , it seems like a simple system . Jack says he doesn ' t get it , while Crow says Bruno is really amazing . Bruno then explains if they can pass this one , they ' ll be in the database ( the computer screen is shown , and after going through a slight digital maze , a door opens revealing Duel Monster Cards on a Duel field ) . Crow wonders what this is . Yusei realizes It ' s a simulation Duel . Bruno understands , and explains Sector Security set up this simulation duel as the password . Crow asks if this means they can ' t proceed any farther unless they solve it . Yusei concludes that it seems so , and states they have 4 minutes remaining . Bruno says the information on the screen ( he doesn ' t finish that sentence ) . He notes the opponents Life Points are at 2300 , why their own life is at 1000 , and continues by saying the opponent has 5 monsters , while in the opponent Spell / Trap zone , there is a set card , and an activated continues spell card known as " The Dark Door " ( when Bruno explains there are 5 monsters on the opponents field , 3 of them are revealed to be " Red Gadget " , " Green Gadget " and " Yellow Gadget " , while the other two are " Ancient Gear Soldier " and " Stronghold the Moving Fortress " . " Red Gadget and " Yellow Gadget " are in defense mode , while " Green Gadget " , " Stronghold the Moving Fortress " and " Ancient Gear Soldier " are in attack mode ) . Bruno then says on their field , they have " Tragoedia " who gains 600 ATK for each card in your hand , so it currently has 3600 because there are 6 cards in their hand . Crow reads the computer text , which says " Win in this turn " . Yusei states since It ' s like this , the set card on the opponents field is troublesome . Crow adds in any case , they just have to make the opponent ' s Life Points go to 0 this turn . Crow walks over to the computer Bruno was sitting on , and tells him and the others to leave this to him ( a small avatar version of Crow appears in the computer screen ) . Crow then states with a monster with 3600 ATK and " Shooting Star Bow - Ceal " ( which was one of the cards in their hand ) , the answer is simple . He then equips the equip Spell to " Green Gadget " , which lowers Its ATK from 1400 to 400 , while the ATK of " Tradoedia " goes from 3600 to 3000 . Crow now commands " Tragoedia " to attack " Green Gadget " ( a Dark / Purple blast shoots out of its mouth ) , but the computer activates the Face - down Trap card " Mirror Force " , which deflects the blast and destroys Crow ' s Monster , shocking him that he lost . Yusei realizes through the effects of " The Dark Door " , both players can only attack once , and finishes saying this won ' t do them any good . Jack grabs Crow roughly telling him he is wasting their precious time . Yusei however states but now they ' ve learned something , and continues by saying that Face - down card is " Mirror Force " . Crow explains it means all of your monsters will be wiped out if they attack , and says this is bad . Jack let ' s go saying his duel wasn ' t even worth watching ( After sitting down on the computer , a small avatar version of Jack appears on the screen ) . Jack then says " Equipping an equip Spell to an opponents monster to lower their attack points , is something you do when you ' re out of tricks ! A duel is power ! Trusting in your own power is a duel ! " Jack then equips the equip Spell " Axe of Despair " to " Tragoedia " , bringing It ' s ATK to 4000 ( the Axe now appears in the hand of " Tragoedia " ) . Jack Commands it to attack " Green Gadget " , but the computer once again activates " Mirror Force " , destroying the Monster . Crow grabs Jack calling him an idiot , and that Yusei said it was " Mirror Force " . Grabbing Crow , Jack gets angry saying he was just checking to see if that set card would change , but Crow says they don ' t have time for that , to which Jack retorts stating he didn ' t ask him . They ' re interrupted as Yusei explains they only have 2 minutes left , and that this is their last chance . Bruno offers to do it , surprising them . Yusei asks if he can win , to which he replies yes . Bruno explains inside his memory , there are only Duel Runners and duels , and finishes by saying he might remember something . Yusei understands and let ' s him do it . Jack is about to complain , but Crow tells him not to , because there ' s no time . Bruno looks at the screen once again , as Crow asks if they can solve this in just 2 minutes ( after this , a small avatar version of Bruno appears in the computer screen ) . Bruno states the first problem is that " Mirror Force " Trap card , and that they must not let that card activate . He concludes the one thing that can seal off " Mirror Force " is " Ancient Gear Soldier " , which has the power to stop Traps from activating when it battles . Jack however says " Ancient Gear Soldier " is on the opponent ' s side of the field . Bruno explains this is where the effect of " Tragoedia " comes into play . He states by discarding a card from your hand , once per turn you gain control of an opponents monster that has the same level as the discarded card . He then states that " Ancient Gear Soldier " is a level 4 , and the only card in his hand is the level 6 " Bird King Alector " . He now notices he has the spell " Cost Down " in his hand , which can reduce all monsters level in his hand by 2 , if he discards a card first . Crow then asks if that means he ' ll change " Bird King Alector " level to 4 , to which Bruno replies exactly . Bruno now activates " Cost Down " ( he discards the " Remove Trap " Spell card from his hand ) , and changes " Bird King Alector " from level 6 to 4 . Bruno then explains through the effect of " Tragoedia " , by discarding " Bird King Alector " , he takes control of " Ancient Gear Soldier " ( the monster now appears on Bruno ' s side ) . Jack sees , and says he ' ll equip " Axe of Despair " to " Ancient Gear Soldier " and then attack " Green Gadget " . Yusei though says not yet , and Bruno says It ' s just as Yusei told him . He explains if he raises the ATK of the stolen " Ancient Gear Soldier " with " Axe of Despair " , and even if he uses " Shooting Star Bow - Ceal " to lower the ATK of " Green Gadget " to 400 , the damage inflicted to the opponent will only be 1900 , and concludes it won ' t be enough . Jack asks him what they should do , but Bruno tells him to look at the screen once more . He says there is one thing that stands out , which is the effect of " Stronghold the Moving Fortress : . Crow though says its ATK is 3000 , but Bruno explains its ATK will only be 3000 when " Green Gadget " , " Yellow Gadget " and " Red Gadget " are on the field , and finishes saying if those 3 aren ' t there , then its original ATK is 0 . Yusei realizes Bruno saw through it . Bruno now discards " Shooting Star Bow - Ceal " to activate " Tribute to The Doomed " , and destroys " Green Gadget " ( The ATK of " Stronghold the Moving Fortress " goes from 3000 to 0 , and it shrinks Note : destroying any of the gadgets would have given the same results ) . Now equipping " Axe of Despair " to " Ancient Gear Soldier " , Its points go from 1300 to 2300 ( the axe now appears in the monsters hand ) . Bruno then commands " Ancient Gear Soldier " to attack " Stronghold the Moving Fortress " ( the monster tries to run away , but gets hit by the axe . The Robots points go from 2300 to 0 ) . The Security bot ' s light now turns from red to green , and It ' s door opens ( the computer screen now says " Clear " ) . Everyone is glad Bruno did it , but he says they need to hurry and match the fingerprint . Seconds later , a match is found on the computer , and the figure appears on screen . Everyone is shocked , to which Bruno asks if they know this person . Yusei answers him by saying " This guy is . . . the Vice - Directer of Sector Security , It ' s Lazar . Featured Puzzle Duel . On Jack , Crow and Bruno ' s field , they have " Tragoedia " ( 10 / ? / ? ) in face - up Attack Position , have six cards in their hand ( " Axe of Despair " , " Remove Trap " , " Cost Down " , " Tribute to the Doomed " , " Shooting Star Bow - Ceal " and " Bird King Alector " ) , and 1000 Life Points . Due to the second effect of " Tragoedia " , it gains 600 ATK for each card in Jack , Crow , and Bruno ' s hand ( " Tragoedia " : ? → 3600 / ? → 3600 ) . Crow , Jack , and Bruno must win in one turn . The Password Robot has " Red Gadget " ( 4 / 1300 / 1500 ) and " Yellow Gadget " ( 4 / 1200 / 1200 ) in Defense Position , " Green Gadget " ( 4 / 1400 / 600 ) , " Ancient Gear Soldier " ( 4 / 1300 / 1300 ) , and " Stronghold the Moving Fortress " ( 4 / ? / 2000 ) in Attack Position , a set card ( " Mirror Force " ) , " The Dark Door " , and 2300 Life Points . Due to the effect of " The Dark Door " , both players can only attack with one monster during their respective turns . Due to the last effect of " Stronghold the Moving Fortress " , its ATK becomes 3000 as " Green Gadget " , " Red Gadget " , and " Yellow Gadget " are all present on the Password Robot ' s side of the field . Crow ' s attempt Crow activates " Shooting Star Bow - Ceal " , equipping it to " Green Gadget " and decreasing its ATK by 1000 ( " Green Gadget " : 1400 → 400 / 600 ; " Tragoedia " : 3600 → 3000 / 3600 → 3000 ) . " Tragoedia " attacks " Green Gadget " , but the Password Robot activates its face - down " Mirror Force " to destroy " Tragoedia " . Jack ' s attempt Jack activates " Axe of Despair " , equipping it to " Tragoedia " and increasing its ATK by 1000 ( " Tragoedia " : 3600 → 3000 → 4000 / 3600 → 3000 ) . Assuming the system swapped out the face - down card , Jack uses " Tragoedia " to attack " Green Gadget " , but the Password Robot activates its face - down " Mirror Force " to destroy " Tragoedia " . Bruno ' s attempt Bruno activates " Cost Down " to lower the Level of every monster in his hand and field by two ( " Tragoedia " : 10 → 8 ; 3600 → 3000 / 3600 → 3000 ) by discarding " Remove Trap " ( " Tragoedia " : 3000 → 2400 / 3000 → 2400 ) . This lowers the Level of " Bird King Alector " ( " Bird King Alector " : 6 → 4 ) . Bruno then activates the third effect of " Tragoedia " to send " Bird King Alector " from his hand to the Graveyard ( " Tragoedia " : 2400 → 1800 / 2400 → 1800 ) and take control of " Ancient Gear Soldier " ( as their Levels were the same ) . Bruno activates " Tribute to the Doomed " to destroy " Green Gadget " by discarding " Shooting Star Bow - Ceal " ( " Tragoedia " : 1800 → 600 / 1800 → 600 ; " Stronghold the Moving Fortress " : 3000 → 0 / 2000 ) . Bruno then activates " Axe of Despair " , equipping it to " Ancient Gear Soldier " and increasing its ATK by 1000 ( " Ancient Gear Soldier " : 1300 → 2300 / 1300 ; " Tragoedia " : 600 → 0 / 600 → 0 ) . " Ancient Gear Soldier " attacks and destroys " Stronghold the Moving Fortress " ( Password Robot 2300 → 0 ) ( The Password Robot can ' t activate " Mirror Force " in response as the effect of " Ancient Gear Soldier " forbids it from activating Spell or Trap Cards until the end of the Damage Step ) .
