Dr. Stone Wiki

Joker is the fifty-second episode of the Dr. Stone anime, and the seventeenth episode of the third season.


Realizing Ibara's trap and who set up the fake petrification device, Senku and his friends retreat back into the Mobile Lab where they must counter Ibara's next and dastardly move, to envelop the entire island with the petrification light! With no time to waste, the Kingdom of Science split up where Senku's team charges aboard the Perseus until Moz appears to "cover his tracks with the latter"! Senku's group finds themselves cornered into a room, where he is forced to unveil their final trump card!

Plot Details[]

Magma fires the gun randomly, scaring many of Ibara's men into jumping overboard. Nikki retrieves the pistol, which has only two shots remaining. Moz knocks Yo and the pistol overboard and defeats Kinro, so everyone retreats into Perseus' lower decks. Ibara follows to gloat at his victory, but Senku reveals he was actually looking for Hyoga, petrified in his cell since they reached the island, whom Senku now revives. Ibara flees after realizing Senku can revive statues, correctly deducing they are reassembling the master. Hyoga considers joining Moz as Moz's value of strength is similar to his own, but when he learns Moz only values women for their beauty, he chooses Senku and engages Moz in a spear duel. Kirisame approaches the Perseus with Medusa. Senku and the others flee ashore while Moz defeats Hyoga easily. Ibara orders a soldier, Oarashi, to activate Medusa on the island, even though it would petrify him too, claiming it is the will of the master. Kirisame, who remembers the master as a kind man, finally questions Ibara's abuse of power, just as Taiju appears with the master's statue for everyone to see. Angered at being exposed, Ibara petrifies Kirisame and pushes her overboard, but before he can petrify anyone else, Yo shoots his hand so he drops the Medusa, which Yo catches before it can sink underwater.
