The Micronauts are lost on the strangest, most dangerous planet they've ever visited—Earth! But as they adventure through this land of giants, they make a senses-shattering discovery! They are not the first visitors from Microspace to visit Earth. In fact, a very dangerous colony was established on the planet long ago... and it may hold the key to saving their universe from imminent destruction.
