Episode 15, Nanotroopers. With his detachment, Johnny Winger makes it safely back to Earth, but fragments of the rogue asteroid diverted by Red Hammer still impact the planet, causing destruction across the globe. Worse, a saboteur has turned up inside Quantum Corps, a nanotrooper never suspected. Now, the troopers are suspicious of all ANAD systems. With Doc Frost gone, the troopers find a new mentor to follow, a nanobotic likeness of Doc himself. But can Doc II be trusted? The Red Hammer cartel still has plans to defeat Quantum Corps and Doc II is the key.
