This scum Mr. Yang
is driving Cruella insane!
So sayeth the great Lord of Darkness Sauron:
or he will send Darth Vader to terminate you.

Mr. Yang was a recurring villain/serial killer and one of the main antagonist on the TV show Psych. She was the daughter of an even more crazy and bloodthristy serial killer, Mr. Yin, who was responsible for her becoming who she was.

She was portrayed by Ally Sheedy.


Mr. Yang makes her first appearance, to play her game with Shawn Spencer. After Henry's adamant protests to the contrary, Shawn accepts her proposition, vowing to bring her to justice. She first kidnapped Shawn and Gus' waitress and held her hostage. After leaving several cryptic clues for Shawn, the hostage was finally returned, but replaced with Shawn's mother, Madeline Spencer. After strapping a bomb to Madeline, Yang sat and watched as the SBPD swarmed a drive-in theater looking for her. Shawn found her car, and she finally came face-to-face with her target. She revealed to Shawn that she was going to write a book about them, and was finally arrested.

Mary revealed that Yin is her father, and while Shawn will remain in prison on account for all of the Yin/Yang murders, not knowing any other existence.
