The Nanogoo are a collective consciousness of microscopic claytronic robots that eat everything in their patch, and are considered one of the major threats to the universe and every living thing in it.
The Nanogoo Spheres are the the main transport system for the Nanogoo. They are giant balls that are bright silver in color and can range in various different sizes.
The Nanogoo Shifters are entities made of claytronic nanobots that can shapeshift to spy and infiltrate enemy territory. In their true form, they are large grey slimy metallic beasts with glowing red eyes.
