Earth Inferno (#17-20)

The Authority face the Earth itself, which is about to catastrophically reverse its magnetic poles, spurred on to do so by a former Doctor who was stripped of his powers when he went renegade. In exchange for one hour's worth of full power from the current Doctor, the renegade agrees to save humanity. With no other options, the Authority evacuate the entire population of Earth to alternate Earths, then agree to the exchange. The renegade takes on and almost completely destroys the Authority with his new power before the full scope of his powers and experience catches up to him, and he is overwhelmed with empathy for all the living creatures left on Earth. Apollo and the Engineer kill him and the Earth's population returns home, some thrilled by their adventures
