The robotic cartoon adventure series The Transformers begins its second season with the episode Autobot Spike, in which one of the human allies of the Autobots in their ongoing battle against the Decepticons literally loses his mind to a super-Transformer. Autobot Spike is one of the few single-episode storylines to be found this season. Many of the other scenarios take up two episodes or more, notably Dinobot Island, wherein the discovery of a remote island populated by prehistoric beasts leads to a serious schism in the time-space continuum; Megatrons Master Plan, in which the leader of the evil Decepticons does his best to turn public opinion against the Autobots; and Desertion of the Dinobots, which finds the title characters rebelling against their enslavement by the robots and trying to claim the Autobots home planet as their own. The best of The Transformers two-parters during the series second season is The Key to Vector Sigma, a story built around a computer from the planet Alpatrian with which the Decepticons intend to bestow artificial intelligence upon their newly created flunkies, the Stunticons. ~ Hal Erickson, All Movie Guide
