Tragoedia ( character ) Tragoedia ( トラゴエディア , " Toragoedia " ) is a character version of the card " Tragoedia " and the central antagonist of the " Yu - Gi - Oh ! GX " manga . He was formerly a citizen of Kul Elna who survived the village ' s massacre , as he was not in the village when the massacre took place . This ultimately resulted in the creation of a powerful " ka " and his attempt to destroy the Pharaoh ' s kingdom . He was sealed by several of the Pharaoh ' s priests , only to be revived in modern times by possessing the bodies of others , with his goal being the restoration of his body and revenge on the " ghosts " of the priests through the spirit cards . Biography . Back in the times of ancient Egypt when Aknamkanon ruled , the man who would become Tragoedia was a citizen of the village of Kul Elna . He gained an upper position in the Pharaoh ' s entourage as a court astronomer . However , after learning about the massacre that decimated his village ( ordered by Akhenaden so as to create the Millennium Items ) , his hatred and anger led to the creation of an extremely corrupted and powerful " Ka " , that being Tragoedia . While judged by the original priests who held the Millennium Rod and Millennium Scale , and by Akhenaden himself , the criminal was judged through the " ba " Winged Kuriboh , which was white at the time , but turned dark after coming into contact with the malice inside the man ' s heart . Tragoedia was manifested in monster form , and attempted to kill the priests , but his power had been weakened due to the absorption of his heart by Winged Kuriboh , and Winged Kuriboh absorbed the Feather of Ma ' at to prevent Tragoedia from reclaiming his heart upon the priests commands . Tragoedia was sealed then , though his power was so great that he remained aware of himself even while sealed , and so his tablet was smashed and its remains buried in the royal tombs . Akhenaden and the other priests vowed to take the memory of what happened there to their graves , so as not to alarm the Pharaoh . Three thousand years later the burial chamber in which Tragoedia lay sealed was opened by archeologists , and he " thanked " them by possessing them , and slowly began body - hopping , finding suitable hosts to further his needs . Ultimately he would end up in Mr . Phoenix ' s body , using his position as a card designer at I2 to create the Legendary Planets archetype , its astronomy theme symbolizing his original self ' s occupation in the Pharaoh ' s courts . He would later imply that he also used this time to craft a unique Deck for himself . Tragoedia would later come to possess the head of the American Duel Academy , with the intention of using someone of a high position to utilize many pawns . He would come to reveal that in Mr . Phoenix ' s absence , he had raised Aster Phoenix to be his perfect pawn . It was also known that he adopted David Rabb as his son , because the boy had no known relatives . He acted through MacKenzie , and was able to possess David , whom he sent to Duel Academy ' s main branch with Reggie MacKenzie in order to obtain the spirit card in which his heart was still sealed - " Winged Kuriboh " . After Rabb ' s defeat at the hands of Chazz Princeton , Tragoedia used Reggie as his main enforcer , but didn ' t appear to have the same influence over her as she did over David , as she plotted against him at the same time , due to his being weakened by the Feather of Ma ' at that had been transferred to " Light and Darkness Dragon " , when the spirit attacked Rabb . Principal Mackenzie journeys to the main branch of Duel Academy for the exchange battle between the Japanese and American Academies , and Tragoedia begins using James Crocodile Cook to continue the quest that Reggie had abandoned . Jim would identify a potential new " card " for Tragoedia , " King " Atticus Rhodes , though he was prevented from using the Shadow Games initially , as Tragoedia wanted to savour the experience of his plans coming to fruition . Through his MacKenzie persona , he manipulated both Aster Phoenix and Adrian Gecko without need of possession , while using Jim , Jesse Anderson and Axel Brodie to gather energy through the Legendary Planets . After Aster defeated Atticus he ( having prevented Atticus from preventing his loss ) seized the opportunity to make Atticus one of his pawns , also influencing Adrian at the same time . He then gave Aster one of the Legendary Planets , " The Grand Jupiter . " After Adrian was defeated by Jaden Yuki , he reclaimed the Legendary Planet he had given him , " The Despair Uranus , " and also reclaimed " The Splendid Venus " from Reggie after she spied on him in a warehouse containing his tablet . Ultimately , he succeeded in his plot to regain his heart by possessing Atticus Rhodes and defeating Jaden Yuki . He then called Atticus , Jesse , Axel , and Jim to the warehouse he had stored his tablet in , reclaiming the " Planets " he had given them . He then sent a message to Aster normally , calling him to the warehouse . When Aster found his fellow students and Atticus unconscious , Tragoedia revealed that he was possessing MacKenzie , and revealed his previous host to Aster ; his father , Mr . Phoenix . Aster furiously challenged Tragoedia to a Duel , but was defeated by Tragoedia ' s own " Planet " , " the Supremacy Sun " , his defeat and anger supplying the final power needed to resurrect Tragoedia , as had been his purpose since Tragoedia had raised him . Using the gathered energy from the " Legendary Planets " , he extracts his heart from " Winged Kuriboh " and becomes whole again . It is as this point that he is finally revealed to Jaden and Chazz as an actual monster , briefly abandoning MacKenzie and appearing before them in monster form . Revealing that he has had no ambition other than completing himself from the beginning , he faces Jaden and Chazz in a final Shadow Game using MacKenzie . After giving them a turn ' s head start , Tragoedia brings out his ace monster , " The Supremacy Sun " , and begins to toy with them , constantly replenishing his Life Points and even destroying Chazz ' s " Light and Darkness Dragon " despite his previous fear of the spirit , but he ultimately loses to their combined monster , " Ma ' at " . Tragoedia then abandons Principal MacKenzie , and muses that he could easily crush Jaden and Chazz like insects . With Tragoedia weakened by his own Shadow Game , Winged Kuriboh and Light and Darkness Dragon ultimately sacrifice themselves to seal away Tragoedia once and for all . Abilities . As an embodiment of wickedness and corruption , Tragoedia can possess people at will and use the power of darkness as a means to restrain , kill or plunge any Duel into a dark counterpart of itself , a Shadow Game , though his influence can be removed by defeating a person in a Shadow Game ( or he abandons them due to the fact that the subsequent Penalty Game renders them useless to them ) . He can also remove or alter the memories of those he possesses , allowing him to remain unhindered himself . While possessing MacKenzie , he exhibited the ability to levitate on more than one occasion . When using his abilities , he is often surrounded by a dark shadow similar to Shadow Miasma in appearance . He is however extremely weak against the powers of the " Light and Darkness Dragon " , calling it the Feather of Ma ' at , as when Chazz met Koyo Hibiki , Winged Kuriboh ' s spirit transferred the Feather of Ma ' at it had absorbed in Egypt into Chazz ' s " Light and Darkness Dragon " card , thus giving it its spirit . He was so powerful that he remained conscious even while sealed in a stone tablet , and unlike most " ka " , had a much more defined intelligence . His full power is difficult to judge , as he is only seen briefly at full power , and never exhibits any notable difference in strength due to immediately repossessing MacKenzie and Dueling Chazz and Jaden , though at full power , he claimed that he could easily take over the world if he felt the need to do so , and when defeated in a Shadow Game , though he was weakened , he was not outright defeated until the intervention of " Light and Darkness Dragon " and " Winged Kuriboh .
