Li H'sen Chang

Li H'sen Chang (stage name "the Celestial Chang") did the bidding of Magnus Greel, a 51st century war criminal escaped to the 19th century.

Biography
Originally, Chang was but a Chinese peasant farmer who discovered Greel, who had escaped to this time period in a time cabinet. Believing Greel to be the god Weng-Chiang, Chang hid him from Imperial troops, and later became the leader of the Tong of the Black Scorpion, a cult devoted to doing Greel's bidding.

Greel granted Chang mental powers "undreamed of in this century", amongst them hypnosis, telepathy, and telekinesis. Chang used these abilities as part of a magic act in London, where he was publicized as a "master of magic and mesmerism". During his performances at the Palace Theatre in Limehouse, Chang mesmerized his audiences by reading minds and levitating young women above the floor. Unbeknown to anyone, Chang was using his on-stage persona as a cover while he lead the search for Greel's time cabinet. Chang's secondary duties included attending to his master, who hid in the basement of the Palace Theater, and to procure young women to replenish Greel's bodily degeneration. During his act, Chang would hypnotize women who volunteered to participate, causing them to mindlessly do his bidding once the show was over.

Once the Fourth Doctor began to investigate the disappearances of women in the area, Chang tried to kill him on the behalf of Greel, both directly and through the Tong. His repeated failures in this respect earned him the wrath of his master, who summarily dismissed him. As a penalty, Greel secretly hid the body of a dead theater custodian inside Li H'sen Chang's magic box, which later tumbled out on-stage in front of Chang's stunned audience. Chang quickly fled the scene, but was cornered by the Doctor and threw himself to the giant rats living in the London sewers (their size increased by Greel).

The rats ravaged him and tore off a leg, but Chang survived. His loyalty to Greel quickly turned to hate once he realized that it was Greel who ruined his performance. Chang later surprised the Doctor and Leela by greeting them as they arrived at the Tong's hideout.

While smoking opium to dull the pain, he explained how he had come to meet Greel and helped smuggle him out of China. He lamented that he would have been scheduled to perform at Buckingham Palace for the Queen before dying of his wounds. (DW: The Talons of Weng-Chiang).

Legacy
Although he himself was dead, Chang's daughter Hsien-Ko Chang returned to the Doctor's life in 1937, where it was revealed that her father's exposure to Zygma energy had resulted in her mutating in the womb to become apparently immortal, appearing to be only twenty-five while chronologically her mid-sixties. Using the reactivated Mr. Sin, Hsien-Ko attempted to draw Greel into the present so that she could punish him for his role in her father's death- believing that the Doctor's interference was all that allowed Chang to die with dignity-, but the Doctor halted this plan due to both his own moral objections and the dangerous temporal paradoxes that could result from such an action (MA: The Shadow of Weng-Chiang).

Behind the scenes

 * A Caucasian actor, John Bennett, portrayed Li H'Sen Chang, using makeup and an accent, a practice probably not acceptable today, but more widespread in 1976, when The Talons of Weng-Chiang was made and aired.
 * The story's writer Robert Holmes favoured breaking this six-episode Doctor Who serial into a four-episode story followed by a two-episode story (or vice versa). In the case of The Talons of Weng-Chiang, the first four episodes concentrate more on Li H'Sen Chang. Following Chang's death, the final two episodes of the serial center more on Greel himself and on his other henchman, Mr. Sin.
