Hello there. Ever since G1 came out, I always thought Autobots were called Autobots because they were both auto's "cars" and robots. Now do Michele Bay's first movie, Optimus Prime called them selves "Autonomous Robotic Organisms, or Autobots for short". So, my question is, where does the name Decepticon come from? Yes their military-based, yes their "deceiving", conniving, and they "con". But that really doesn't really say where their name derives from! Has it been mentioned anywhere?
