Yung Hee Tyson is Mike Tyson's adoptive daughter. She is 18 years old and of Korean descent. When she was a baby, her mother left her on Mike Tyson's doorstep. Mike decided to raise her as his own daughter. Mike sometimes forgets what her name is and believes she told him to "stop living for himself" when she was a baby. She has plans of going to college, but Mike is not sure whether he wants her to go. She often finds herself solving mysteries with her father, the Marquess of Queensberry, and Pigeon. Pigeon seems to have a sexual obsession with Yung, as seen in many episodes
Yung Hee is level-headed, intelligent, and driven. She exhibits patience with her dad's strange nature at times and can be independent when needed. She is however still a bit naïve about relationships, even gaining a crush on Pigeon after seeing a picture of his human form.
