Gravitational Mass Allocation: Blob's main superhuman ability was to become virtually immovable at will as long as he was in contact with the ground. He did this by bonding himself to the earth beneath him by force of will, which in effect created a mono-directional increase of gravity beneath him. This gravity field extended about five feet in radius from his center of balance. Thus if there were sufficient power to uproot him, it would take the ground beneath his feet in an area corresponding to the radius of the field. Through intense concentration, the Blob was able to extend the gravity field beneath him farther than five feet.
