Terraforming Racer

The Terraforming Racer was seen by many species as the ultimate planetary annihilation weapon. Created by the Kranctons it was a massive machine full of many legs designed to destroy what was on the planet, whether that was alive or natural, and reshape it to suit the needs of those conquering the planet. A Terraforming Racer is over 100 miles in size, and for a planet the size of the Earth it can reshape the planet of that size to the requirements of the conqueror in an hour. No Racer has ever been known to have been destroyed whilst terraforming a planet.
