Mythyrian Numbers Mythyrian " Numbers " , known as Legendary " Numbers " ( の , " Densetsu no Nanbāzu " ) in the Japanese version , are " Number " cards which are located in Number ruins across the world , protected by guardians . They play a major part of the " Mythyrian Numbers War " and " Barian Emperor Onslaught " arcs of the " Yu - Gi - Oh ! ZEXAL " anime . Each one of these cards is connected to a figure from history , as the canon portrays it . Design . Mythyrian " Numbers " are part of original 100 " Number " cards , but unique . Each of these " Numbers " correspond to a legend inscribed on the walls of the ruins , telling the story of the person who occupied that location in a previous era , before they became ruins due to the ravages of time . Mach , for example , was a Pegasus who served a legendary knight , Dumon . Three knights who lived in his land attempted to usurp the King , but were intercepted by Mach and his master . Since the hero was unwilling to kill his former comrades , both master and steed were eventually defeated and killed . However , the hero ' s fellow knights regretted their actions and they buried him and Mach together . Mach later became the Mythyrian " Number " spirit guardian of " " . History . In " Yu - Gi - Oh ! ZEXAL " , the Mythyrian " Numbers " are unique " Number s " whose cards were used by Astral eons ago to seal Don Thousand in Barian World ' s Barian Sea . If Astral obtains them all , he would discover the location of the Numeron Code . However , if the Barian deity Don Thousand obtains them all , he would be fully revived , which later turns out to be false as Don Thousand revealed to Yuma and Astral that if all 7 of the Mythyrian Numbers were procured from their ruins , the majority of his power will then be restored . There is a connection between the Mythyrian " Numbers " and the Seven Barian Emperors , which was revealed when Astral absorbed " Numbers " " 44 " and " 54 " . He saw Dumon ' s past life as a knight owning a Pegasus and Alito ' s past life as a gladiator . Don Thousand hinted at Vector ' s past life as a mad king . When Astral questioned Jinlon if the person he was talking about was Mizar , the latter confirmed this . However , Mizar , even with Jinlon revealing Mizar ' s past life as a dragon tamer , refused to believe he was once a human . Afterwards , Roku found a statue of a military commander named Kiraku Souhachi at the Duel Lodge , which bore great resemblance to the Barian Emperor Girag , with Ponta confirming that Kiraku Souhachi was , indeed , Girag ' s past life as a shogun . When Vector released Don Thousand , Thousand revealed that in order to fully revive him , Vector must collect these seven Mythyrian " Number " cards . Later , Vector convinced Mizar and Dumon to take part in this endeavor , with the assistance of Mr . Heartland , who is now an insect . Also , Yuma Tsukumo and Astral resolved to obtain the Mythyrian " Numbers " after receiving a message from the former ' s father . In the first of the ruins , Yuma obtained the first Mythyrian " Number " , " " , from Mach . Next , " Number 96 " acquired the second Mythyrian " Number " , " " from Battle Ox . After that , Alito acquired the third Mythyrian " Number " , " " from Number 54 ' s guardian , but gave it to Nistro so he could control him . After they lost the Tag Duel , Nistro gave Yuma the " Number " . The group next set off to the fourth set of ruins , where Kite began a Duel with Jinlon , whom he subsequently defeats , obtaining " " . Returning to Heartland City , Yuma discovered by television that yet another " Number " was found , this time inside the Duel Lodge , and rushed to take it . Girag went to the same ruins , but Ponta took over his body and challenged Yuma to a Duel for " " and Girag ' s body . Yuma won and obtained the " Number " . When the Different Dimension Airship stopped at sea , Rio was called to the bottom of the sea by the guardian Abyss . Following her along with Yuma and Astral , Shark eventually defeated Abyss ' " " after being shown memories from his past life , using the ruins ' second Mythyrian " Number " , " " , putting most of the Mythyrian " Numbers " into the possession of Yuma and his allies . Yuma and Astral defeated Number 96 at the cost of Astral sacrificing himself to protect Yuma from a fatal attack , leaving Number 65 ' s in Vector ' s control due to his absorption of the Forbidden Number ' s sealed form after his return to its progenitor - Don Thousand . If these cards or their corresponding Number C ' s clash with the corresponding " Number 10X " ( or " Number C10X " ) they awaken the original memories of the legendary figure described in the ruins . This also causes any malignant influence from Don Thousand to disappear from the respective Emperor . " Number 54 " was summoned by Yuma to emancipate Alito from Don Thousand ' s control after it clashed with " , " restoring Alito ' s real memories and revealed Don Thousand to be the orchestrator behind his tragic execution . Number 64 was to given to Alito by Yuma in order to release Girag from Don Thousand ' s control with the aid of Ponta , who returned after having been eaten by Girag . Alito succeeded in releasing Girag ' s true memories in a Duel , but he ( along with Girag and Ponta ) were absorbed by Vector ( who obtained " " along with them ) . During their second rematch on the Moon , Kite Summoned against Mizar ' s " " and restored the Barian ' s original memories . After the clash in the Duel , " Number 46 , " along with " Number 107 " and " " resonate to form " " , which Kite receives . After acknowledging Mizar ' s superiority as a dragon master , Kite gives the " Number 100 " card to Mizar before dying . During Vector and Nash ' s Duel , Nash was able to usurp control of " " and have it destroy " " , causing Vector ' s original memories to be awakened . When Don Thousand absorbed Vector and Mizar , he gains all their " Numbers " along with Numbers 46 , 64 , and 65 . Nash would obtain those Mythyrian " Numbers " after defeating Don Thousand by cooperating with Yuma and Astral . However , he eventually gave those along with all of his collected Numbers to Astral before vanishing . This puts all the Mythyrian " Numbers " in the ZEXAL wielders possession . Mythyrian Numbers .
