Yu - Gi - Oh ! Capsule Monsters - Episode 006 " Trial of Light and Shadow " is the sixth episode of the miniseries " Yu - Gi - Oh ! Capsule Monsters " . Summary . After entering the portal from last episode , the group find themselves on a floating island above the clouds . After a little banter , Joey asks how they get off and Tea assumes that they just need to pass the test . Yugi collapses from the strain of using the armor in the previous trial . Tristan says that he needs a doctor , but Solomon reminds them that they have better than that and take Yugi to a cave to be healed by Happy Lover . Afterwards Yugi states that he feels like a new man , but Tea insists that he sit this trial out . Yugi protests and tries to get up , but he collapses , completely out of energy . Tristan says that poor Yugi is sleeping like a baby . They make Yugi a make - shift bed with a rolled up towel under his head Solomon ' s vest acting as a blanket . Solomon believes that the armor takes more of a toll on Yugi than they know of . Joey thinks it ' s time to pay Yugi back for saving them in the last trial by completing this one while Yugi rests . A bright light suddenly shines from the entrance , leaving behind another scroll . Joey gives it to Solomon to translate it . It says : " Once a day the unbreakable stone appears in the Valley of Light . To achieve the impossible , fight with a power that ' s greater than physical might . " Solomon feels that it ' ll be quite a challenge , but Joey says that itlll be fine . Tea wishes to stay with Yugi , so the three guys walk off and Tea re - enters the cave and we see Yugi asleep . Joey thinks there ' s someone down in the giant crack , despite it only being the echo of his call . Tristan corrects him , but Joey is adamant . Solomon thinks they should find a way down . The three scale along the cliffedge , eventually making it to the bottom . Joey and Tristan think that maybe Solomon read the scroll wrong as it ' s very dark at the bottom . Solomon says that it ' s the only valley for miles . Just then , the sun rises over the valley , lighting it up . Solomon explains how it all makes sense . Tristan then asks where this unbreakable stone is , and Joey points to a large monolith . Joey asks what they ' re meant to do . Solomon states that the ancient text read that this was an unbreakable stone , so the trial is to break it . Tristan wants a hammer and chisel , but Joey suggests using their monsters instead . Tristan summons forth Thunder Kid and attacks the Monolith . Despite the strength of the bolt of lightning , there ' s not even a scratch on it . Joey hears a sound and feels there ' s more to the trial than just the monolith . The group turns and looks up to the cliffedge to see a strange ball of glowing light , from which appears a Prisman . They all think the monster is pretty small , so Joey summons forth Flame Swordsman . Both he and Thunder Kid attack , knocking Prisman far away , but yet undamaged . . . Joey orders Flame Swordsman to attack again , but ends up running out and standing between the two monsters . Prisman grabs Joey , but Joey knocks him back down with a punch to the face . Joey and Tristan start arguing over who gets to beat up the little guy . Solomon , angrily , tells them to stop fighting as they ' re on the same side . Both call for an attack , but as they do , the sun shines brightly overhead . Prisman raises its arms , glowing with a rainbow - colored aura before firing a massive beam of light at the gang ' s monsters . Solomon explains that , because of what Prisman is , he ' s able to focus the sun ' s light into a massive energy beam and because they ' re above the clouds , the sun is stronger than ever . As the gang hides and tries to think of a plan , Prisman ' s attacks destroy the rocks they ' re hiding behind . Solomon is hurt and as Prisman powers up an attack , Tristan sends in Thunder Kid to help , tackling Prisman and making him fire up at the cliff edge instead . Joey tells Tristan to work on breaking the rock while he deals with the glassy foe , narrowly avoding a beam to the face . Tristan doesn ' t like the plan , but avoids a blast directed at him , the beam hitting the monolith instead . Tristan feels he ' s lucky to be alive , but realizes that the beam made a hole in the stone . Acting on this , he tells Thunder Kid to follow his lead . Joey and Solomon are running for their lives as they ' re being constantly shot at . Tristan shouts an insult to Prisman , goading the crystal terror to attack him and Thunder Kid instead . Prisman takes a shot that Tristan and Thunder Kid sidestep away from . Both make a face at him , only to sidestep his shot again . Joey doesn ' t think much of what they ' re doing , but they continue to insult Prisman , who starts rapidly firing at them . Meanwhile , Yami is running from the mysterious shadowed being again . He meets up with Dark Magician , fusing with him , but as he turns to face the new foe , the armor cracks and disappears . Yugi awakes with a start , realizing it was only a dream . Tea is wetting a cloth when she notices the boys left the scroll behind . She starts as Yugi asks what it was they left behind . Yugi asks where everyone is and Tea explains to him how they went off and gives Yugi the scroll , hoping he can read it . He can ' t , but switches to Yami so he can read it . Yugi appears in spirit to Yami , asking what it means . Yami says that it ' s only half the riddle as the riddle should say something about shadow as well , but it only talks about light . Not knowing of where to find the rest of the riddle , Tea asks if they can look for it in the shade . Yami suddenly realises about the riddle , and they go inside as Tea asks how she solved it . Yami says it ' s because she suggested to read it in the shade , the act of which shows the second half of the riddle . Yami reads it to himself , saying how the others are in trouble . . . Prisman manages to hit Thunder Kid in the shoulder , so Tristan also feels the pain . Joey wants to come help , but Tristan tells him to trust what he ' s doing , although tells Joey to pull down on his right eye . Joey does so , only to have Tristan tell him that he ' s officially a distraction . Joey bounces around as he ' s shot at by an angry Prisman . Tristan tells Thunder Kid to attack the now greatly widened hole in the monolith , cracks shooting all over the monolith , shattering it to pieces , causing Prisman to stare in shock . Joey congratulates Tristan on breaking the rock , making Tristan start to gloat , but Joey shoots him down with a well - timed insult . In the background , Prisman is flailing about . Picking up a large piece of the monolith , Joey Tristan and Thunder Kid run at Prisman using a monolith piece as a shield to get close enough for Flame Swordsman to swoop in and destroy it . As they rejoice , the base of the monolith cracks and breaks apart , a shadow standing in the dust from the rubble . Yami and Tea are scaling the cliffsidee as Yami explains how the second part of the riddle says that once the creature of light is destroyed , a new and more dangerous monster is born . They need to find the others first , but it ' s too late as they arrive just as the creature of shadows appears . It turns out the creature of shadows is a Skull Guardian , leaping toward the others and slashing at them , its sword - arms hitting the ground as they manage to avoid the attack . Flame Swordsman rushes in to attack , only to have it be parried . Thunder Kid fires a bolt of lightning but also gets blocked . Skull Guardian throws out waves of dark energy that knock the two monsters away , hurting Joey and Tristan . Solomon tells them to fall back as Skull Guardian slams its swords on the ground . A wave of energy is released that follows close behind the gang as they run away . Yami summons forth Dark Magician , fusing with him . Charging in for an attack , Yami blocks the counter strike with his capsule launcher and uses a dark magic attack to knock Skull Guardian away . As the being falls to the ground , a light glows where the monolith once stood . Joey calls for an attack with Flame Swordsman , but Yami blocks that too . Joey asks what he was doing as they have to defeat this creature to clear the level , however Yami disagrees . Tea notices a box in the light from the monolith as Yami leaves his fused form . Yami says that they already passed the trial and that the rest of the riddle explained it all . The others say that they read the whole thing , but Yami explains about reading the scroll in both light and the shade . The second part said : " When light is extinguished the true test begins for a creature of darkness it brings . But only the righteous and peaceful shall pass and receive the endowment of wings . " Yami opens the chest to reveal many pairs of white - feathered wings . As Yami finishes explaining , the masked figure from Yami ' s vision from the last episode appears to them , explaining that this test was a test of their character . If they ' d have continued their attack , they ' d have failed . The masked man doesn ' t say his name , but assured them he ' s a friend . He states that he oversees the trials and congratulates them for completing the second one , but warns them that the next three are much harder . As the figure goes to leave , Yami asks what will happen if they fail or win over the trials . To fail means to be stuck in this world until the next warriors arrive . To win will prove Yami is a true king and the power they deserve will be theirs . Yami protests that he doesn ' t want any power , but the masked figure says there are those who do and Yami must claim it , lest those with evil intentions get to it first . The gang all has the Icarus - style wings on , and they decide to fly for the door that ' s floating in the sky . Tea is concerned for Yugi , but he reassures her that he ' s never felt better . Solomon wishes he had half the gusto Yugi has . Tristan apologises to Yugi for them having to rely on him again . Joey disagrees , saying that it was a group effort , reminding Tristan about all the ideas he came up with . The gang leaps off the edge of the island , flying towards the door . Alex , still waiting on the steps , smiles darkly , saying that it ' s only a matter of time before the greatest power in the world is his . . .
