Celestial Toymaker The Celestial Toymaker ( also known as the Crystal Guardian and the Mandarin ) was a powerful being who ensnared sentient beings in apparently childish games , with their freedom as the stakes . However , the Toymaker hated to lose and the games were always rigged in his favour . Nature and powers . According to the Twelfth Doctor , the Toymaker was spawned in the chaos before time . ( COMIC : " Relative Dimensions " ) According to the Sixth Doctor , he originated in another universe before this one and was hauled into the Doctor ' s universe by some kind of catastrophe . Because of this , the usual laws of physics didn ' t apply to him . The Toymaker himself stated that while in the beginnings of the universe he used his powers for other things , he eventually got bored of thousands of millennia of pointless creation and pointless destruction , and found a new source of amusement — games . ( AUDIO : " The Nightmare Fair " ) The Toymaker once claimed to be the embodiment of one of the fundamental forces of the universe , much like the Guardians of Time . Whereas the White and Black Guardian s personified the absolutes of morality , however , the Toymaker was the avatar of games and illusions , known as the Crystal Guardian . ( PROSE : " The Quantum Archangel " ) He had a sister , known as Hecuba or the Queen of Time , who liked to play with time as much as her brother played with toys . ( AUDIO : " The Queen of Time " ) The Seventh Doctor described the Toymaker as " a spirit of mischief from the infancy of the universe " to his companions Ace and Hex . ( AUDIO : " The Magic Mousetrap " ) He was one of the Elder Gods . ( AUDIO : " Black and White " ) Within his realm , the Celestial Toyroom , the Toymaker commanded immense powers , but they were limited by the rules he set for any particular game , although he could bend these rules or " forget " to mention them to his opponents if he so chose . He himself was immortal and invulnerable , and appeared capable of space and time travel at will . For some reason he chose to appear in the guise of a middle - aged human dressed as a Chinese mandarin . During the course of a game , one of the players might die outright or they might lose , in which case , the Toymaker would have total control over their life and personality , perpetually . ( TV : " The Celestial Toymaker " ) Apart from these children ' s games , the Toymaker sometimes played in person against his " guests " , most often games of chance such as cards or dice . There is evidence to suggest that if he was fairly beaten in such a game , the other player was allowed to go free , but if his opponent lost or tried to cheat he became another exhibit in the Toyroom . Such opponents included Gaylord Lefevre , a professional gambler from the America n west ; and a Roman soldier — though it is unclear if the latter played fairly and thus gained his freedom . ( COMIC : " The Greatest Gamble " ) However , by some accounts , the Toymaker feared the outer - universe so boldly that he feared the idea of being forced to leave his toyroom . In this account , the Twelfth Doctor helped create a new one for him , leaving him drifting through time and space . ( COMIC : " Relative Dimensions " ) Personal history . First encounters with Doctor . According to one source , the First Doctor learned of the Toymaker when he was a youth at the Prydonian Academy . The Time Lord s ' data banks described him only as a vague legend . The Doctor and his friends Rallon and Millennia who , like the Doctor belonged to a clique known as the Deca , investigated the legend , travelling to the Toyroom in a stolen TARDIS . The Toymaker was in a dormant , disembodied state , but on their arrival he possessed Rallon and made Millennia one of his living toys . The Doctor defeated him , and the Toymaker allowed him to leave , knowing that he would become an even more worthy opponent given time to mature . ( PROSE : " Divided Loyalties " ) During the latter days of his first incarnation , the Toymaker drew the Doctor ' s TARDIS back to his realm and made the Doctor and his companions play his games again . This time the Toymaker arranged things so that even if they won , the Toyroom would vanish completely at their moment of victory , leaving him the only survivor and the Doctor and his companions his subjects forever . The Doctor outwitted the Toymaker again and escaped , leaving his realm in chaos . ( TV : " The Celestial Toymaker " ) Rallon had been keeping the Toymaker ' s powers in check since he was first possessed . He made the Toymaker abide by the rules of his games to allow the Doctor to escape . ( PROSE : " Divided Loyalties " ) At the end of this adventure , the Doctor believed , incorrectly , that since he had won , the Toyroom no longer existed . ( TV : " The Celestial Toymaker " ) Rebuilding the Toyroom . According to one source , the Toymaker was so terrified of the universe outside of his Toyroom that he refused to allow himself to leave it . When the Toyroom became old and began to break down , the Toymaker feared that its contents would break out into the universe . He trapped the Twelfth Doctor and Clara Oswald inside , wanting to steal the Doctor ' s TARDIS in order to keep the Toyroom contained . The Doctor allowed him to take the TARDIS , then made his way into the console room and ejected the Toyroom . The Toymaker was then left with a contained Toyroom once more , " A lonely god , drifting through time and space in his magical toy box . " ( COMIC : " Relative Dimensions " ) Leaving the Toyroom . The Toymaker discovered that after centuries of existence , Rallon ' s body was dying . He set out to ensnare the Doctor again and hatched a complex plot to turn his companions against him and absorb the Doctor as a new host . He was thwarted when Rallon forced himself to undergo multiple regeneration s consecutively . The trauma expelled the Toymaker from his body . A projection of Rallon ' s potential future self merged with the Toymaker to ensure that the full powers of the immortal continued to be kept under control . While waiting for his Toyroom to repair itself , the Toymaker decided to take his servant Stefan to Earth to seek amusement . After seeing the idea in Tegan Jovanka ' s mind , he decided to take him to Blackpool . ( PROSE : " Divided Loyalties " ) The Toymaker , now calling himself the Mandarin , appeared in Blackpool using a thrill ride , Space Mountain , as his base of operations , manufactured deadly video arcade games . He was stopped by the Sixth Doctor and placed in an impenetrable force field . Because the Mandarin ' s mental energy maintained the force field , the Doctor had set it up so that he could never escape it . ( AUDIO : " The Nightmare Fair " ) Still calling himself the Mandarin , he escaped and played chess against Fenric during the latter ' s imprisonment . The Mandarin found himself on the verge of being outplayed , but slowly realised that , in this case , playing for a stalemate would be a victory of sorts . ( PROSE : " Games " ) Battles with the Eighth Doctor . The Toymaker trapped the Eighth Doctor in a replica of the village of Stockbridge . Here he forced the Doctor to play games for control of a reality - warping alien device called the Imagineum . The Toymaker ' s pawn this time was a replica of the Doctor himself . The Doctor persuaded his double to turn against his master . With the Toymaker distracted , the Doctor used the Imagineum to create a replica Toymaker , which he set against the original . A stalemate ensued . The Doctor destroyed the Imagineum and freed Stockbridge from the Toyroom . The Toymaker was trapped in apparently perpetual battle with himself . ( COMIC : " Endgame " ) The Toymaker later captured the Doctor ' s TARDIS and took it to his Toyshop . He transformed the Eighth Doctor into a puppet . The Doctor ' s companion , Charley , was forced by the Toymaker to take part in his riddle , but was tricked by the Toyshop which shrunk to 0 % of its original size and the body he was using was destroyed within it . The Toymaker swore that when his new body had formed he would take his revenge upon the Doctor and Charley , who had escaped the Toyshop ' s destruction . ( AUDIO : " Solitaire " ) The Seventh Doctor ' s trap . The Toymaker somehow regained full control of his powers and lured several people into his domain , including the Seventh Doctor and his companions Ace and Hex . Working under the Doctor ' s leadership , the group of victims were successful in defeating the Toymaker and imprisoning his essence in a doll ( or so it seemed ) . Each of them ate a piece of the doll , dividing the Toymaker so that he would no longer be capable of using his powers . The Doctor concocted an elaborate plan to keep control over the fragments of the Toymaker in the minds of each member of the group until the Toymaker withered away forever . As this plan involved the Doctor forgetting having made the plan in the first place , he wound up short - circuiting it . In the end , it was revealed that the Toymaker had been in control all along , allowing himself to be absorbed into humanity so that he could " feel what it was like to lose " . Finally , one of the people involved , the chessmaster Swapnil Khan , managed to trap the Toymaker in a perpetual stalemate in his own dimension , but not before the Toymaker had reduced everyone except the Doctor , Ace , Hex , and Khan ' s daughter Queenie Glasscock to wooden dolls .
