In the wake of the Decepticons' efforts to draw Cybertron into Earth's orbit, Megatron is presumed to have been killed. In his place, Starscream vows to destroy the earth, and to that end he draws upon the scientific know-how of Dr. Archivil. It is up to Optimus Prime to save mankind -- and in this, he finds himself with a most unexpected ally. First broadcast in America on December 1, 1984, "Countdown to Extinction" served to introduce the character of Frenzy. ~ Hal Erickson, All Movie Guide
