Iron Face Chouryou

Iron Face Zhang Liao was the previous RyuuRanger who joined the Gorma Tribe, becoming immortal. 20 years prior to the series, he fell in love with a human who gave birth to his son, Ryou Tenkasei. After Yuko was born, Liao was summoned back to his master, Archbishop Saw. He was sent to fight the Dairangers after the Gorma Triumvirate failed to do so, only to stop upon hearing his son is the new RyuuRanger.

Zhang Liao eventually saw the error of his ways and turned on his master. Receiving a fatal blow for his troubles, he collapsed and was dying. Ryou held him close, and then they appeared, the four spirits of the other original Dairangers. They had come for him, to tell him they forgave him. He passed on the ancient knowledge of Dairen'oh to the new Dairangers before he died.

He is named after a military general of China in the years 169 to 222.
