Yu - Gi - Oh ! Capsule Monsters - Episode 007 " Red - Eyes Black Curse " is the seventh episode of the miniseries " Yu - Gi - Oh ! Capsule Monsters " . Summary . Tristan is complaining about all they ' ve been through so far . As he finishes talking , the floor beneath his foot collapses , Joey and Solomon catching him from almost certain doom . Solomon says to just do as he does , the floor breaking out from under him as he says it . The others pull the 2 up . Solomon complains that he needs a vacation , Tea stating that this WAS supposed to be a vacation and that she wants out . Yugi says the only way out is to win the game , Joey piping in about going to find a clue . Tristan quips about Joey ' s notable cluelessness , but Tea says they should support him as things have always worked out in the end . Yugi reminds them about how much of what they ' ve done so far has been thanks to Joey . Yugi wonders about who made this game - world they ' re in as Yami appears in spirit form , saying how he thinks they ' ll find out in the final stages . Joey talks about how every trial started with a riddle , but finding it is the hard part . Turning round as he heards a high - pitched screech , he ' s narrowly missed by a diving Red - Eyes Black Dragon . Joey hides behind a rock as the dragon swoops round for another attack . Going past him , Red - Eyes Black Dragon turns for another assault . Joey tries to run as he sees its claws , the downburst of wind from the low swoop taking him off his feet . Turning a final time , Red - Eyes Black Dragon firsts off an attack towards Joey . . . Yugi looks thoughtful as Yami appears and asks him what ' s on his mind . Yugi tells of the strange , masked man who keeps popping up . A flashback of the man appearing in the last episode shows . Yugi feels there may be others playing the game too , and hopes that they ' re not ahead of the gang . Tea calls to Yugi , bringing him out of his train of thought as she points across a gorge to a small alter with a scroll on it . Tea summons out Dark Witch , who flies across and gets the scroll , handing it to Tea before going back to her capsule . She hands it to Solomon who then reads it : " To gain the prize of thy desire , locate the peak that spits fire . The Blade of Chaos thou must release , to bring about a lasting peace . " Yugi points out that the riddle refers to the giant volcano beside them . Solomon asks about the rest of the riddle . Tristan says they should just get on with it and climb the volcano . Joey is blown off his feet again by Red - Eyes Black Dragon as it swoops past again . Joey readies a capsule , but holds back as Red - Eyes Black Dragon dives for another attack , not wanting to hurt his favorite monster . Red - Eyes Black Dragon flies straight past again as Joey realises that he ' s not being attacked at all . Tristan moans at how Joey manages to avoid climbing by " conveniently " disappearing . Tea tells him to stop complaining and just keep climbing . The rock Tristan grabs falls away , sending him hurtling down towards the river of lava . He manages to grab a rock to stop himself falling . Unfortunately , it happens to be a capsule rock , which breaks open and sends both itself and Tristan falling towards the lava again . The others cry out for him , but his new monster is a Thunder Dragon that flies him back up . Yugi realizes that they shouldn ' t bother climbing , but use their monsters instead . Téa summons forth Dark Witch while Yugi switches to Yami and summoned Dark Magician , fusing to become the Dark Warrior . Taking hold of Solomon , all 3 fly up to the top . As they fly to the top , Tea spots a sword sticking out the rim of the volcano . Solomon complains he can ’ t see it . Thinking the chaos means the lava flow , they figure that pulling out the sword will stop it . Standing on a ledge near the top , Tristan starts to wuss out , but Yami steps in saying that he ' ll go to pull out the sword since he has the armor . Walking to the side of the volcano , Yami looks up just in time to see an Inferno Fire Blast coming at him . Jumping out the way , he looks in the direction from which the blast came . . . a figure standing there in armor that looks like it came from a Red - Eyes Black Dragon , much like Yami ' s Dark Warrior armor . The figure . . . is Joey . Joey tells of how he gained armor like Yugi has while riding the back of Red - Eyes Black Dragon , they fused . Joey doesn ' t seem himself . . . too arrogant . He figures that , because of the power he now possesses , he can finish the game by himself . Solomon notices this and tells Tristan not to attack Joey as something else is possessing him . Joey gets full of himself again and fires a blast at Tea and Solomon . Joey powers another blast and fires it at Yami , who avoids it as Joey fires a third , hitting him with it before charging and tackling Yami . Yami tries to talk Joey out of his confused state . Joey goes for a flurry of punches ; Yugi says they can ' t attack their best friend , but Yami disagrees and fires 3 balls of light at Joey who avoids and continues his attack . Yami flies away , Joey in chase . As he flies after Yami , Joey starts to realize in his mind that something was wrong when he fused with Red - Eyes Black Dragon . Tea looks up as she gets up from her attack , noticing the sword in the volcano is starting to sink . Solomon realizes that they need to pull the sword out fast , but because Yami is busy , Tristan goes to do so . As he runs toward the sword , Joey appears from the sky , swinging his halberd - like weapon to create a wave to knock Tristan back . Joey goes back to fighting Yami as the rest of the gang make it to the sword , pulling on it to try and set it free . Joey creates a shock wave again , knocking the gang back down off the rim again . Solomon says they need to take Joey out before they can get to the sword . He says that they all need to attack simultaneously , despite the risk of hurting Joey . Tristan summons forth both Thunder Kid and Thunder Dragon while Téa summons out Dark Witch . Solomon says to wait for an opening . Téa protests , saying how Joey might be trapped in the game forever , but Solomon says it ' s better than standing around doing nothing and have them all trapped . Yugi ( in spirit form ) knows that Joey ' s still inside and that he ' ll save him . Yami and Joey collide , a bright light enveloping everything with only a black ball of energy in the center . In some kind of mind - scape , Joey ' s voice calls to Yugi , asking for help . Joey tells of how something was wrong with Red - Eyes Black Dragon before they merged . Joey says the only way to break the spell is to destroy the armor that ' s controlling him . Yugi protests , as it would mean destroying Joey too , but Joey knows that already . The sword is still steadily sinking . Joey flies down in front of the gang , protecting the sword . Tristan says it ' s time to attack , but Téa falls to her knees , unable to attack her friend . Yami says that he ' ll do the deed . Yami says he ' s prepares to do it and readies an attack . Joey says that he doesn ' t have the guts to attack , but Joey ' s mind stops the armor , holding it still so it ' s unable to defend itself from Yami ' s attack . Joey ( in spirit form ) tells Yami to attack , and Yami blasts Joey and the armor with a Dark Magic attack , the armor and Red - Eyes Black Dragon flying off from Joey , who collapses . The gang all run over to check if he ' s alright , Tristan taking his pulse . Relieved that he ' s alright , but out of time as the sword fully sinks into the volcano , the gang is dismayed as Red - Eyes Black Dragon comes roaring out of the clouds . Red - Eyes Black Dragon fires off a blast as Yami creates a Magic Cylinder , sending the attack right back at Red - Eyes Black Dragon , knocking it out of the sky . It crashes nearby on the volcano . Getting up , Joey walks over to the unconscious dragon , he climbs atop Red - Eyes Black Dragon to show the others of a second sword that ' s sticking out of Red - Eyes Black Dragon ' s back . Pulling on it , beams of black and red light shine from the wound , Joey pulls the sword out . Yami shouts to Joey , telling him that sword is the source of the curse , and they can still pass the test . Joey tosses the sword into the air , Yami blasting it with a Dark Magic attack , the sword shattering as it hits . The pendant around Tea ' s neck shines as another trial is over and passed . Yami explains that the sword in the volcano was a decoy , with the real Blade of Chaos being the one stuck in Red - Eyes Black Dragon . Joey becomes all modest , but the gang congratulate him for being so brave . Joey tells Red - Eyes Black Dragon to get some rest as it becomes a capsule , placing itself in Joey ' s hand , just before Joey collapses from using the armor . Yami defuses with Dark Magician , he himself feeling weakened . A rock opens in the volcano wall , a large portal of light revealed . Yugi feels that it ' s the way out , but Tea makes a sarcastic remark anyway . Tristan , now carrying a sleeping Joey , hopes the next trial is in outer space as he ' s no longer a fan of gravity . Joey starts to order donuts in his sleep . The gang laugh as they run towards the door . Alex says to himself that what they say about Yami is true , if anyone can complete the challenges and set Alex ' s spirit free , it is Yami . Then he removes his mask to reveal that he looks like Dr . Alex Brisbane . . Trivia . Note : When Tristan slips the second time Yugi ' s voice sounds like Téa .
