Uighur

The warden of Cassandra prison and an Uyghur whose ancestors lived in ancient Mongolia. He fights using the Taizan-ryu Sojo Ben (泰山流双条鞭, "Taishan Style Twin Streak Whip") style.

In the spin-off prequel, Uighur was originally a prisoner of Cassandra who had survived five separate executions until his meeting with Raoh. Raoh gauges his strength and learns of Uighur's dream to create his own legend. This earns Raoh's approval and Uighur is named the new Warden of Cassandra, at Gion's expense.

Uighur's cruel and bloody reign built a legend of terror at Cassandra, as he reveled in the screams of the tortured souls locked within its walls. Uighur stood before Kenshiro, who had stormed the prison to free the imprisoned Toki. He managed to overwhelm Kenshiro with his true form, Moko Hakyoku Do (蒙古覇極道, "Tao of the Mongolian Champion"), a charging tackle which concentrates all his muscle and strength into one shoulder. However, Kenshiro recovered and countered the move by crushing Uighur's shoulder with Hokuto Koretsu Ha, before finishing him with the Hokuto Hyakuretsu Ken. Uighur was sent crashing into an unmarked grave that he had originally dug for Kenshiro, his gargantuan body contorting itself to fit inside before Uighur explodes. Somehow Uighur survives long enough to rise up from his grave and issue a final warning that Kenshiro and Toki mustn't meet, before the rest of his mutilated body finally explodes.

In the anime adaptation, Uighur has an assistant warden, Targel who comes with a plan to pit the prisoner Bella against Kenshiro. Uighur's death scene is changed so ne longer says "UWARABA" instead saying "Lord Ken-oh." Additionally Uighur says "help me" in the anime, whilst Uighur is defiant to Kenshiro in the manga.
