Shadi is a member of a faction of the Tomb Keeper ' s clan who watched over the Millennium Items , the Eye , Key , Ring and Scales in Kul Elna in the Valley of the Kings . A thief once tried to steal the Millennium Ring , but Shadi ' s men managed to chase and capture him . Maximillion J . Pegasus was in the area and saw what happened . Fearing what they were going to do to the man , he offered to pay them all the money he for the Ring if they let the man go . Shadi advised him not to flaunt his wealth in that area . He said that the man stole artifacts from a sacred place and was to be punished only for act of theft . He said that the value of the Ring was irrelevant , but priceless . He asked if Pegasus was a traveler and warned him that the village was created by grave robbers and that were common . He advised that he leave , saying that the thing he wanted was not there ; it was not a place where the sadness of losing a loved one is healed . Pegasus was surprised that Shadi knew exactly what he was thinking , so he secretly followed him . Shadi and his men took the thief to a house of sun dried brick , which was an entrance to a hidden underground temple . The thief was dragged onto an altar and knelt before Shadi . He apologized for the theft and begged that he not be killed . Shadi explained that he did not intend to condemn him for stealing the Ring , but wanted to learn if he was a chose one , someone who the Ring would accept as its bearer . Shadi gave the Ring to his men , who put its rope around the thief ' s neck . This caused the Ring to pierce into the thief ' s body and burn him to death . Assured that he was not chosen by the Ring , Shadi reinserted it into the Tablet of the Pharaoh ' s Memories . Shadi ' s men found Pegasus spying on them and brought him to the alter . Pegasus begged to be let go , promising not to tell anyone what he saw . However , Shadi told him that he had seen something he should not have seen and consequently the only way to leave was to become a chosen bearer of a Millennium Item . He took the Millennium Eye from the tablet to test Pegasus . He explained that if Pegasus was deemed worthy , he would be granted his dearest wish and see his beloved once more . The Eye accepted Pegasus and briefly showed him an apparition of Cyndia . Sometime afterwards , Pegasus painted a portrait of Shadi , which he hung up in his castle next to one of Cyndia . However he did not like to talk about either of the paintings . Taking in orphans . Shadi entered the home of an abusive man , who had many orphans steal for him . Among the orphans were Diva , Mani , and Sera . He approached the orphans and pushed their foreheads , causing a gold symbol to momentarily appear on them . He then immobilized the man , and killed him with the Quantum Cube . He then took the orphans in with him . Once , while talking to the orphans , Bakura ' s father came in , wanting to buy the Millennium Ring . Shadi replied that it was free , and told him to see if the Ring saw him as worthy . The man put on the Ring , but it rejected him , and he told his son who came with him to put on the Ring instead . His son did so , but Dark Bakura awakened , and murdered Shadi . Before dying , he handed Diva the Quantum Cube . Since then , Shadi became a ghost . Meeting the Ishtars . Shadi met Marik and Ishizu Ishtar when they had snuck out of their house , against their family ' s laws , for two hours . He knew that they were tomb guardians and warned them that from then on their fate would be a tragedy splitting their family with blood and that it was the will of the Pharaoh . He then disappeared into the crowd despite Ishizu calling him back . When Marik regained control after Dark Marik killed his father , Shadi appeared in their house and reiterated that the tragedy splitting their family with blood was the will of the Pharaoh . Meeting Yugi . Shadi went to Domino Museum to pass judgment on the curator , Curator Kanekura and the archaeologist , Professor Yoshimori , both of whom had entered and taken items from an Egyptian tomb . He first played a Shadow Game , Question of Truth , with Kanekura , in which he performed the Weighing of the Heart , using the Millennium Scales . He placed the Feather of Ma ' at in one side of the Scales and as he asked Kanekura a series of questions , his sins would add weight to the other side . He asked a series of questions to test Kanekura ' s morality . As he lied the sins side of the Scales gained weight . Before the last question , Shadi used an illusion to transform Kanekura ' s chair into Ammit . The final question was if Kanekura had defiled the territory of the Gods for money . He begged Shadi to stop , offering to pay any amount of money . However this caused the sins side of the scales to hit the table . Shadi then inflicted a Penalty Game , where Ammit was let loose in Kanekura ' s soul room to devour his soul , killing him . On leaving the museum , Shadi spotted Yugi Mutou and learned that he was the holder of the Millennium Puzzle . He then used the Millennium Key to enter Yugi ' s soul room , but found two rooms ; one filled with toys belonging to Yugi and a darker one belonging to Dark Yugi . Dark Yugi appeared inside his room and invited Shadi in , if he dared . Shadi introduced himself as an unwanted guest , who had entered to learn the power of the Millennium Puzzle . If the power was needed he would draw it into his bloodline . Not willing to simply show Shadi the power , Dark Yugi proposed a Shadow Game , the Labyrinth Treasure Hunt ; somewhere inside the soul , was Dark Yugi ' s true room and if Shadi could locate it he would find what he ' s looking for . Shadi accepted the game , but then mentioned that once he entered someone ' s room , he could redecorate it to control the individual or change their personality . Dark Yugi started the game and the place turned into a maze of doors and staircases . Shadi began searching , but the doors were filled with traps . Eventually Shadi was left dangling above a bottomless pit . Dark Yugi saved him and advised that he leave . Shadi parted , thinking that he had lost the game , but Dark Yugi assured him that it was only the beginning . Shadi spoke with Yugi after leaving his mind and saw that Yugi was completely unaware of the existence of " the other Yugi " . As he departed , Shadi told Yugi his name , with that being the first time he had ever disclosed that detail with anyone . Shadi spared Yoshimori a Shadow Game , as he planned to use him as a test for Yugi . He redecorated Yoshimori ' s soul room . After Kanekura ' s death , Yugi , Sugoroku Mutou , Katsuya Jonouchi , and Anzu Mazaki came to Yoshimori ' s office at Domino University to cheer him up . Possessed by Shadi , Yoshimori knocked out Sugoroku and began strangling Jonouchi , until Anzu walloped him with a globe . Shadi let Yoshimori chase Jonouchi around the building , while he redecorated Anzu ' s soul to use her as a tool in the Shadow Game . With Anzu held hostage , Dark Yugi was forced to meet Shadi on the roof for the game . To win the game , the Trial of the Mind a player had to make their opponent show weakness in their heart . Anzu was stood on a board suspended over the side of a building by a series of ropes attached to the building by ushebti . Four ushebti represented Yugi ' s heart , while one represented Shadi ' s . The ushebti broke up when weakness was detected in its corresponding player ' s heart . Causing all Dark Yugi ' s ushebti to break would let Anzu fall and causing Shadi ' s ushebti to break would let the Millennium Key slide to Anzu ' s hand and free her from Shadi ' s possession . Seeing Anzu in danger immediately caused one ushebti to break . Shadi put Dark Yugi through a series of game tests , which he needed to pass without letting his ushebti break . For the first stage , Hell Quiz , Shadi created illusions of corpses , which crawled on the ground and tried to grab and climb onto Dark Yugi . The only way for Dark Yugi to make the corpses disappear was the determine their true nature , by answering the riddle , " What creeps on the ground and clings to pillars ? " . The corpses were what crept on the ground and Dark Yugi was the pillar . The answer was one ' s own shadow , which Dark Yugi managed to figure out . For the second stage , he got Dark Yugi to solve another riddle . He showed him nine face - down slabs and had him restrained by an illusion of Ammit , who would devour his soul if he did not answer correctly within five minutes . The slabs were said to reflect Ammit and Dark Yugi had to tell him what was under the middle slab . The nine slabs consisted of eight pairs and an odd one in the middle . Dark Yugi realized that Ammit ' s mouth was her only feature before the slabs that she did not have two of and correctly guessed that as the middle piece . Shadi ' s last test for Dark Yugi , the Game of Death , involved an illusion of Jonouchi . The illusion and Dark Yugi had to take turns tossing the Millennium Puzzle to point in the direction their opponent had to walk two floor tile , until one walked off the edge to fall to their death . Jonouchi taunted Yugi just how he did as a bully . Yugi briefly gained control of his body and wept , causing two ushebti to shatter . Unsure if it was the real Jonouchi or an illusion , Dark Yugi refused to take his turns in the game . Shadi was shocked at this decision . Jonouchi forced Dark Yugi to the edge and Dark Yugi refused to take his turn , explaining that he trusted Jonouchi . The illusion then faded away . The last rope supporting Anzu ' s platform began to break , but the real Jonouchi arrived and held it up . Surprised at how the friends supported each other , Shadi ' s ushebti shattered and Anzu was restored to normal . Jonouchi struggled to hold up the board as the possessed professor was trying to attack him . Dark Yugi helped Anzu climb back to the building and instructed Jonouchi to touch the professor with the Key . Dark Yugi taught Shadi that unity is the power of the Millennium Puzzle . Shadi was threatened to leave by Yugi ' s friends . He left beaten , but pleased . His bloodline had been searching for someone like Dark Yugi and perhaps he might be able to open " that door " . World of Memories . Shadi got Bobasa to hold the Key and Scales . When Dark Yugi and his companions went to Domino City Museum for Dark Yugi to regain his memories , Shadi sent Bobasa to serve as their guide . They were initially uncertain about trusting Bobasa , due to his association with Shadi , who had endangered their lives before . Bobasa tried to defend this , saying that Shadi had been testing to see if Dark Yugi was the pharaoh they had been waiting for for 3000 years . During the Shadow RPG Hasan appeared before the pharaoh , who had fallen into a chasm . After advising the pharaoh to rest , he introduced himself as the one who watches all memories and warned the pharaoh that a great battle was about to begin . When the Millennium Items had been placed in the Millennium Stone , Bobasa transformed into Hasan , whom he introduced as his other self and the spirit of the stone tablet . Shadi , as Hasan , served as a non - player character in the RPG , whose duty was to reveal the hiding place of the pharaoh ' s forgotten name after Zorc Necrophades rises from his slumber . He told Yugi , Jonouchi , Anzu and Honda that the pharaoh ' s name rests in the holy place where his soul sleeps , which Yugi realized was his tomb . Hasan then flew away to protect the pharaoh . As Zorc attacked the pharaoh and his priests , whose bodies had been immobilized , Hasan flew in and intercepted the blast . He explained to the pharaoh how he was fulfilling his duty to Akhenamkhanen by protecting the pharaoh until the end . During the final battle with Zorc , Hasan gave his life defending the pharaoh , Yugi , Jonouchi , Anzu and Honda from another of Zorc ' s attacks . His mask cracked in the process , causing them to realize that he was Shadi . Games . Shadi took part in or orchestrated the following games .
