Ma Yongcheng (1468 – 1526), also known as The Butcher, was one of the Eight Tigers, a group of powerful Templar eunuchs that controlled the Chinese imperial court during the reign of the Ming dynasty Zhengde Emperor.
He played a role in the purge of the Chinese Assassins after the ascendance of the Jiajing Emperor, and the Assassins caught in their attempts to kill the Templars were executed by Yongcheng with the lingchi method.
In 1526, while the Assassin Shao Jun was captured by the Templars, Gao Feng, the warden of the prison, threatened to turn the Assassin over to Ma Yongcheng, who would torture her in order to make her talk. When Jun escaped her cell, she assassinated Feng while her Mentor, Wang Yangming, tracked down Ma Yongcheng and eliminated him.
