"Earthmen...we are peaceful beings. And you have tried to destroy us. But you cannot succeed. You and your people will pay for this act of aggression. "This is the voice of the Mysterons. We know that you can hear us, Earthmen. Our retaliation will be slow, but nonetheless effective. It will mean the ultimate destruction of life on Earth. It will be useless for you to resist, for we have discovered the secret of reversing matter...as you have just witnessed. "One of you will be under our control. (It was quickly made obvious that the Mysterons meant Captain Black, for he had been responsible for the unprovoked attack that had just been made.) YOU will be instrumental in avenging the Mysterons. OUR FIRST ACT OF RETALIATION WILL BE TO ASSASSINATE YOUR WORLD PRESIDENT."
