Transformers was a cartoon series that ran from 1984 to 1987. It started as a three part mini-series, ultimately culminating in a full feature film released in 1986. The Hasbro toy line of transformers preceded the TV series, and Transformer toys continue to be popular today, fueled by the success of the Transformer live-action full feature films released in the 2000’s and 2010’s.
The cartoon basically revolved around the battle between the good robots (Autobots) and the bad robots (Decepticons). During the Cybertronian War, the Autobots and Decepticons crashed into Earth. After millions of years, some seismic event resurrects the robots from under the ground, whereby the Autobots, headed up by Optimus Prime, continued their business of trying to defeat the Decepticons, headed up by Megatron. All of the robots could “transform” themselves from everyday objects, such as jet planes and automobiles, to formidable robots (and vice versa).
