Ultimate Knight ( (さい) (きょう) のナイト Saikyō no Naito) is the 166th chapter of the Dr. Stone manga.


A member of Stanley's unit remarks the aerial battle is done. Indeed, Senku uses the same method to bring down the enemy ship, he used before and the engine stalls. However, Senku and Ryusui's is also brought down. Ryusui tells Stanley to come out of the wreckage but it is not Stanley but rather a member of squad.

Back to the Perseus, the enemy announces it is time for their leader to appear. Stanley is then ejected from the submarine, Stanley uses his pistol and overpowers Mozu and Matsukaze. Stanley reports the enemy has been defeated.

At the castle, Xeno receives the report and relishes in his victory. Xeno states it was good to send his most reliable knight out. However, he gets a transmission from Senku to tell him that he was not the only one who sent his knight. Shocked, Xeno is then confronted by Tsukasa who holds him at swordpoint.
