"The Transformers" was a cartoon series
which aired for 5 seasons during the 1980s. The characters
were giant-sized robots who had the ability to transform
into seemingly innocent objects like cars and planes
to fool their enemies.
The conflict that took place during the
series was between 2 main groups, the Autobots, who
were basically the good guys, and only wanted to exist
in peace, and the Decepticons, who were the bad guys
which wanted to conquer as much of the known universe
as they could.
