Mark of the Dragon A Mark of the Dragon , known as a Dragon Birthmark ( 竜の痣 " Ryuu no Aza " ) in the Japanese version , is a special mark that indicates that a person is a Signer . The symbol of the dragon is the Ouroboros , which is either a dragon , a lizard or a serpent biting its own tail . The symbol represents unity , infinity or a never ending cycle . Five thousand years ago , an ancient civilization known as the People of the Stars worshiped a mystical light called the Dragon Star , which was prayed on by the leader of the People of the Stars , the Star Dragon King , at the top of the Stairway to the Dragon Star . When the star shined , the King knew it would be a message from their god , the Crimson Dragon . The dragon was then Summoned to imprison an incarnation of an ancient evil in the earth . This evil is represented in the Nazca Lines . According to legend , the Crimson Dragon could only be Summoned with the help of the Signers , whose individual marks either represented the Heart , Hand , Tail , Wings , Foot and Head of the dragon . These people were being searched for by a group known as Iliaster , disguised as the Sector Security . According to what Rex Goodwin told Yusei , he organized the Fortune Cup not only to confirm the identities of Yusei Fudo , Akiza Izinski and Luna as Signers , but also in order to awaken their powers so that they could fight against their nemesis , the Dark Signers . Interestingly , in " " and " " , the Crimson Dragon full mark already had the Heart Mark on it . Whether this was an oversight or intentional foreshadowing is unclear , as " Stardust Accelerator " was released in Japan the day after the Japanese air date of Episode 51 , the same with " Reverse of Arcadia " and Episode 97 . Owners . The Head and Tail Marks of the Dragon have been possessed by three other individuals in addition to those listed above . History . Roman Goodwin ' s arm once possessed the Head Mark , but was then severed from his body when Roman became a Dark Signer . Rex then attached Roman ' s severed arm to himself through the powers of the Dark Signers though he stated that there was some resistance . Regardless he was able to call forth the marks of the other Signers as well . Towards the end of episode 64 , Rex lost his Head Mark when it transferred to Yusei , and Yusei ' s Tail Mark then selected Crow as its new owner . In the dub , Yusei assumes that his birthmark is the Head ( which at the time was the Tail ) after seeing Yanagi ' s sketch of the Crimson Dragon . However , it is proven to be a mistake as in the dub of episode 62 Rex confirms that his brother ' s mark is the Head and not the Tail . Abilities & Behavior . The Marks of the Dragon indicate a deep connection between the Signers , and represent this by glowing and throbbing at certain times , such as when a Signer is about to Duel against a Dark Signer . The marks also rival the Dark Signer ' s dark mark . Whenever a Signer is in the presence of one of the Dark Signers , both of their marks react . At times the Signer ' s mark will pulse very painfully on the arm it ' s on . The marks give the Signer in question powers and abilities that no normal being possesses . They can be used to locate other Signers if they focus enough , even if the Signer in question is moving . So far , only Akiza used this ability to locate Yusei when he was kidnapped by a rival team . Also , a Mark of the Dragon will always shield the Signer itself or any companions close to them from harm or any other effect , like having their souls absorbed into an Earthbound Immortal or changes in the timeline . It is also shown that the marks allow them to see the Divine Temple . Anyone else touching the Signer is able to see it as well . They also allow the Signer to activate the small , Ener - D reactors in his Duel Runner and continue to ride it , when all others in the city have stopped functioning . In " Yu - Gi - Oh ! 3D Bonds Beyond Time " , the mark gives the ability to communicate with both Duel Monster and human spirits . Combining Marks . It is possible for a Signer to , temporarily , take control of all 6 Marks of the Dragon at once as the entire Crimson Dragon ' s seal , however the criteria for doing so is sketchy . Yusei Fudo , Jack Atlas , Rex Goodwin and Leo are the only Signers ( past or present ) to have done this , with the Legendary Signer ( who possessed the whole mark on his chest ) being the only one to ( apparently ) do so at will . Rex Goodwin was the second Signer to have the entire seal on his chest ( as opposed to the others who had it on their back ) due to him having the condor mark on his back ( but unlike the Legendary Signer ( who had it on his left pectoral , over his heart ) , Rex had it in the middle of his chest ) . Yusei and Jack did this inadvertently while trying to save Kalin Kessler and Carly Carmine , respectively , and possessing all 5 marks allowed them to draw " Majestic Dragon " , with which to summon their respective Majestic Synchro Monsters . Rex was instead able to do so at will during the 3 - vs - 1 Shadow Turbo Duel against Yusei , Jack and Crow Hogan . However doing so did not seem to afford him anything non - cosmetic . Yusei was also able to take control of all 5 marks at the end of his Duel with Primo . Leo obtained the seal after being on the verge of death . While at this , the Heart Mark formed itself along Luna ' s Hand Mark within the seal , thus revealing it ' s true form of the original seal . In episode 150 , Yusei receives again the Marks from his friends , and his clothes along with his Duel Runner turn gold when he is about to perform an Over Top Clear Mind . in " Yu - Gi - Oh ! 3D Bonds Beyond Time " , The completed mark appears again on Yusei ' s back . It allowed him the ability to travel through time on his Duel Runner to save Maximillion Pegasus from Paradox with the help of Jaden Yuki and Yugi Muto . It also allowed Yusei to use the Crimson Dragon to defend Jaden from a blast from Paradox ' s monster . Non - canon appearances . In " " , the player ' s character has a Mark of the Dragon on their arm . This mark was artificially placed there by Rex Goodwin in an attempt to awaken the Crimson Dragon . It is possible this mark is meant to represent the Crimson Dragon ' s body . In " " the player ' s character gets a Mark of the Dragon at the end of the game . Which mark is not clear since the full mark of the Crimson Dragon is shown . The three main theories are that the player recieves the Head , as Yusei doesn ' t mention a change in his mark , the Tail , giving Yusei the Head , or an unknown mark such as the Body mark , which returns from WC09 , as The Shining Darkness is not available in - game , and therefore , Crow does not have Black - Winged Dragon in the game .
