The incredible power of the Eco Ranger was first demonstrated to the World when the Ecoterrorist group known as Green Vengeance used one to destroy the city of Sao Paulo in 2263. The Eco Ranger, sometimes referred to as a Genesis Machine works on the cascade principal of nanological attack, releasing millions of self-replicating nanite machines capable of breaking down all known artificial materials.
