Episode 20, Nanotroopers. The nanotroopers return to Mesa de Oro shaken but unharmed from their experience with the Sphere at Kokul Gol. They spot a Red Hammer chief nearby and plant a spybot as the agent heads back to the cartel's main base in Tibet. But something goes wrong with the spybot...it's actually a nanobotic version of old Doc Frost, now pressed into a new kind of espionage. Now, Johnny Winger realizes his last link to old Doc Frost is in trouble. He devises a plan, insane and against all regulations, to rescue his bot friend. Winger and two other troopers travel as civilians to Tibet. There they encounter an entity that actually runs the cartel and that will change them forever.
