Overview
When the planet's most dastardly microscopic villains wreak havoc in a realm entirely too small to be viewed by the naked eye, 9-year-old schoolboy Oscar transforms himself into Nanoboy -- the world's smallest superhero. Pals Isaac Neutron and the reformed virus Corona Jane support Nanoboy's heroics as they battle cellular villains, including evil proteins and bacteria.
