Yu - Gi - Oh ! - Episode 171 " Fighting for a Friend - Part 3 " , known as " Reverberating Soul " in the Japanese version , is the one - hundred and seventy - first episode of the " Yu - Gi - Oh ! " second series anime . It first aired in Japan on September 16 , 2003 and in the US on February 26 , 2005 . Summary . While Rebecca Hawkins uses her computer to trace Joey ' s Duel Disk with the KaibaCorp satellite system , Tristan is anxious to go look for Joey . The others warn him that it won ' t help to just wander , but he says that it ' s not just Valon that ' s out to get Joey ; Mai is also tracking him down . The others know that ' s a big problem , as Joey can ' t fight her , but she ' d challenge him regardless . Just then , Rebecca announces that she ' s found Joey . She gives a map to Yami Yugi , and Téa and Tristan insist on coming along . Yami Yugi entrusts Duke Devlin with the task of guarding Rebecca and Prof . Hawkins . He also asks Rebecca if she ' ll trust him , and he promises to bring Yugi back . She nods , and the three rush off . Her grandfather reassures her that it will be all right ; Yami Yugi won ' t be confused by the temptation of the ' Dark ' . Silently , they both put their hopes in his ability to save them . In a nearby car store , Seto Kaiba and Mokuba Kaiba pick a red sports car . The vendor rushes in , demanding what they are doing . Mokuba smugly tells him that they ' re gonna buy it . Kaiba takes out a check and writes quickly . He hands it to the vendor , claiming it ' ll be enough , and drives off with his brother . The vendor looks at the check and is left speachless : Kaiba ' s bought the car for $ 500 , 000 . Joey begins his turn , Summoning new monsters and then bringing out " Hermos " . Valon welcomes this , claiming that when he defeats that power , he ' ll have the perfect victory . Joey fuses " Hermos " to " Rocket Warrior " to create " Rocket Hermos Cannon " , and Valon is taken aback : he wasn ' t expecting any other monster besides his Armor monster s to have the ' Combination ' ability . But he is left without words when the attack becomes a barrage of rockets which cannot be redirected . One by one , the explosions blast him , and after the echoes and smoke fade away , Valon is sprawled on the ground , bruised and with all his armor destroyed . Joey declares that it ' s enough Damage that he wins , but he stops when he sees that the Seal is not disappearing . To his surprise , Valon laughs a bit and climbs to his feet . He acknowledges that the attack hurt a lot , but there was still the effect of Active Guard protecting his Life Points . Joey ends his Turn , knowing that at least the Armor Combo is gone . But Valon still has a trick left . He reveals the Effect of his Spell Card from before : when the Equipped Monster is Destroyed by an enemy ' s Spell , he can duplicate the Effect of that Spell . A copy of " Rocket Hermos Cannon " appears , and he takes his Turn , summoning a new Armor monster for Attacking . He then picks up the copied cannon , eager to try out such a powerful weapon . He Attacks , and the first missile strikes Joey ' s body before the second wipes out his Monster and sends him flying back , smashing into the Seal ' s barrier before dropping to the ground bruised and smoking . Valon ends his Turn , so the temporary copy expires , and he taunts Joey at being beaten by his own legendary weapon . Even before all his Life Points are gone , Joey can ' t even stand up . With hardly a sound , Joey pushes himself to his feet , slowly straightening up , and Valon wonders if he wants to give up and take a break . Joey grins and denies the idea , saying that he won ' t run away . Putting his stance forward again , he raises his faint eyes to Valon and insists he ' ll keep going to the last minute . Valon wonders at this , thinking how Joey ' s never been afraid of him , remembering that this is the guy that Mai has emphasized so much . Joey Draws , Sets one Card , and Ends his Turn . Valon sees he didn ' t Summon any Monsters , and he claims it ' s a pointless struggle - - he ' ll beat him no matter what Card it is . He takes his Turn , strengthening his armor further . He Attacks Directly , and it connects , sending his opponent reeling back . But then , Joey begins to glow , and when the light clears , he is wearing his own suit of Armor - - the Trap card , " Aura Armor " , allowing him to survive the attack and gain armor that ' s on the same level as Valon . But there is one difference : this armor is bound to Joey ' s life , so if it ' s destroyed , he loses . With interest , Valon realizes this makes it a contest to see who will be the last one standing . Joey ' s next turn lets him gather new cards , and he uses them to combine his Armor with the power of his ace monster , his , " Red - Eyes Black Dragon " . In this new form , he gains a high amount of Attacking Power , and he uses it to strike out for maximum Damage . At the last second , Valon blocks the Attack at the expense of one of his armor pieces . Once again , he ' s saved himself , but his hands are trembling . Even so , he realizes it ' s not fear - - it ' s excitement at facing an opponent like none he ' s faced before . He declares that he ' s glad to be fighting a Duel like this , and Joey agrees . Just then , Mai arrives , and she immediately tells Valon off for challenging her rival . She demands that he switch with her , but he refuses , saying he finally understands why she ' s so drawn to fight Joey . He has something the two of them don ' t have ; a simple and direct passion , one that goes beyond Dueling . With that , he and Joey go back to their Duel . On Valon ' s next turn , he uses Monster Reborn to revive the instant - destruction weapon , Buster Pyle . His opponent cuts off his move by activating Scapegoat , which seems like a trivial defensive move . But he clarifies that it ' s not for escaping . Rather , he just fulfilled the conditions for his own Ability , which is able to Destroy all other Monsters on the Field . His armor burns with power , and he takes flight , lunging at Valon , who refuses to let him make it , counterattacking with " Buster Pyle " . The midair collision explodes with a resounding shockwave which clears the field below , and Mai shields her eyes , looking up as a burnt form drops to the ground . Valon lies battered on the ground while Joey lands calmly . As Valon shakily stands up , all of his armor crumbles away , but he insists it ' s not over yet . Joey takes his next move and goes for a direct attack , but Valon comes back with a Trap which will let him break apart his opponent ' s armor and stop the attack . His fist glows with energy , and he strikes out , landing a solid hit to his opponent ' s midsection which leaves him groaning for breath , then knocks him all the way back across the Field . Prone on the ground , Joey ' s " Red - Eyes Black Dragon " is extracted from his Armor , leaving him on his back , barely able to speak . Valon gasps for breath as he recovers from the counterattack , and Joey sways to his feet , similarly bruised and weary . Mai looks on , wondering who will win , and knowing that it would only take one more hit to reveal the answer . Featured Duel : Joey Wheeler vs . Valon - Part 3 . " Duel continues from previous episode . " Joey has 1300 Life Points remaining and controls no cards . Valon has 900 Life Points remaining and controls " Psychic Armor Head " ( 500 / 0 ) " Active Guard " ( 500 / 2500 ) , " Over Boost " ( 500 / 1000 ) , and " Buster Pyle " ( 500 / 0 ) in Attack Position , " The Seal of Orichalcos " , and " Data Brain " ( equipped to " Psychic Armor Head " ) . Turn 9 : Joey Joey has just drawn " Claw of Hermos " . He then Normal Summons " Brigadier of Landstar " ( 900 / 1200 ) in Attack Position . Joey then activates " Monster Reborn " to Special Summon " Rocket Warrior " ( 1500 / 1300 ) from his Graveyard in Attack Position . Joey then activates " The Claw of Hermos " to send the latter and " Rocket Warrior " to the Graveyard and form " Rocket Hermos Cannon " , which Joey equips to " Brigadier of Landstar " . Joey then activates the effect of " Rocket Hermos Cannon " to destroy all of Valon ' s monsters and inflict damage to Valon equal to the total ATK of his monsters . Valon uses the effect of " Active Guard " to prevent him from taking damage this turn before the effect of " Rocket Hermos Cannon " fully resolves . The effect of " Data Brain " then activates , copying Joey ' s " Rocket Hermos Cannon " and generating a copy of it onto Valon ' s side of the Field on his next turn . Since Joey activated the effect of " Rocket Hermos Cannon " , he can ' t declare an attack this turn , so he ends his turn . Turn 10 : Valon Valon draws . On Valon ' s Standby Phase , he activates the second effect of " Psychic Armor Head " to Special Summon the latter ( 0 → 500 / 500 ) from the Graveyard in Attack Position . Valon then Normal Summons " Burning Knuckle " ( 0 → 500 / 1000 ) in Attack Position . Due to the effect of " Burning Knuckle " , it gains 200 ATK for each face - up Armor monster Valon controls . There are currently two ( " Burning Knuckle " : 500 → 900 / 1000 ) . Valon then activates the effect of " Data Brain " to activate the latter card from the Graveyard as the Spell that Joey used to destroy " Psychic Armor Head " . The generated copy of " Rocket Hermos Cannon " appears onto Valon ' s side of the field and Valon equips his copy of " Rocket Hermos Cannon " to " Burning Knuckle " . Valon then activates the effect of " Rocket Hermos Cannon " to destroy all of Joey ' s monsters and inflict damage to Joey equal to the total ATK of his destroyed monsters ( Joey 1300 → 400 ) . Since Valon activated the effect of " Rocket Hermos Cannon " , he can ' t declare an attack this turn , so he ends his turn . On Valon ' s End Phase , the copy of " Rocket Hermos Cannon " generated by " Data Brain " is destroyed since Valon activated the copy through the effect of " Data Brain " . Turn 11 : Joey Joey draws . He then Sets a Card . Turn 12 : Valon Valon draws " Black Hole Shield " and subsequently Normal Summons it ( 0 → 500 / 0 ) in Attack Position ( " Burning Knuckle " : 900 → 1100 / 0 ) . " Burning Knuckle " attack directly , but Joey activates his face - down " Aura Armor " to pay half his Life Points ( Joey 400 → 200 ) , negate the attack , and Special Summon a " Player Token " ( ? / ? ) with ATK and DEF values equal to his own Life Points in Attack Position ( " Player Token " : ? → 200 / ? → 200 ) . ( NOTE : Joey is shown to wear his Player Token ' s " Aura Armor " as if it were his own armor . ) Valon Sets a Card . Turn 13 : Joey Joey draws and subsequently activates " Roll of Fate " to roll a die . Depending on the result , Joey can draw a number of cards equal to the die result and then send cards from the top of his Deck to the Graveyard equal to the die result . He gets a four , so Joey draws four cards and sends the top four Cards of his Deck to the Graveyard . Joey then activates his " Red - Eyes Transmigration " to Tribute his " Red - Eyes Black Dragon " and " Player Token " from his hand and field in order to Ritual Summon " Lord of the Red " ( 2400 / 2000 ) in Attack Position . ( NOTE : Just like with " Aura Armor " , Joey wears the armor of " Lord of the Red " as if it were his own armor . ) " Lord of the Red " attacks " Psychic Armor Head " , but Valon Tributes " Black Hole Shield " via its own effect to prevent " Psychic Armor Head " from being destroyed and nullify the Battle Damage he would have taken ( " Burning Knuckle " : 1100 → 900 / 0 ) . Valon ' s hand contains " My Body as a Shield " and " Kishido Spirit " . Joey then Sets a card ( " Scapegoat " ) . Turn 14 : Valon Valon draws " Monster Reborn " and subsequently activates it to Special Summon " Buster Pyle " ( 0 → 500 / 0 ) from his Graveyard in Attack Position ( " Burning Knuckle " : 900 → 1100 / 0 ) . Joey then activates his face - down " Scapegoat " to Special Summon four " Sheep Tokens " ( 0 / 0 for all ) in Defense Position . Since two Spell Card s have been activated this turn , the effect of " Lord of the Red " activates , destroying all other Monsters on the Field . Turn 15 : Joey Joey draws . " Lord of the Red " attack directly , but Valon activates his face - down " Extinction Fist " to destroy " Lord of the Red " and Special Summon the monsters used to Ritual Summon it to Joey ' s side of the field ; " Red - Eyes Black Dragon " ( 2400 / 2000 ) and the " Player Token " ( 200 / 200 ) are revived in Attack Position . ( Note : In the real game , Token Monsters can ' t be Special Summoned from the Graveyard since they don ' t go to the Graveyard when they are removed from the field ) " Duel concludes next episode .
