On the planet Nano, a war has been raging for about a hundred years between the Nanites and a mysterious race of robots known as the Bio-Mechs. In an effort to win the war, the Bio-Mechs kidnapped citizens and created a crew of biologically-enhanced soldiers with powers known as Chimeras. This was shown to be effective for the Bio-Mechs until a small group of Chimeras escaped. These Chimeras searched for each other and banded together to try and end the century old war.
