Ryan Archer returns to Earth with his Micronauts companions to find his world locked in a massive war with the forces of Baron Karza.  It's down to the wire now: with Baron Karza moments away from carrying out his plan of global genocide, only the Micronauts stand between him and the conquest of the entire Earth dimension. And yet, with Ryan Archer's body on the verge of disintegrating and the vicious Red Falcon out for the team's blood, can they even get to Karza's new citadel in time? See whether or not Earth itself survives as "Invasion" draws to a close.
