Season 3 - Episode 10
A plot of quick-fire action from the beginning, the entire Justice League must stop an orbital recon weapon that eradicates all life on a planet simply by replicating smaller versions itself into the dominant inhabitant. One of the best episodes that cameos numerous superheroes from comic books. The starring hero is the Atom, voiced by John C. McGinley ("Office Space", "Scrubs"), who gains the spotlight as the one Justice League member with the best scientific intelligence and specific ability that can stop the machine from the inside.
