Savage Dragon #0

Savage alien, Emperor Kurr, is poised to wipe out humanity and take over earth as a new home for his people. When a pair of his scientists object to wiping out an entire sentient race, Kurr threatens to kill them and move forward with his plan anyway. Reich and Weiko retrieve a fertilized egg from Kurr's bedchamber (after the emperor brutally kills the woman he bedded down) and, with the next generation of the royal line preserved, they give the Emperor a lobotomy, sterilize him and leave him behind on earth in a burning field.
