- Ho Minh Truon  was Sam Roper and Nhi Houng's son, who, until captured by the KGB, lived as an orphan on the streets of Saigon. 
- When he was captured, he was taken as a bargaining chip by the KGB to the airbase in Omrylkot, Russia, so they could potentially ensure Roper's compliance in stealing the U.S.A.F. jet.
- He was rescued by Stringfellow Hawke and Dominic Santini, who were using Airwolf. They then took him back to the United States to live with Roper and Nhi Houng.
