The names Autobot and Decepticon would have been coined by one of Bob Budiansky, Jim Shooter or Denny O'Neil. Like the faction symbols, they're obviously not very deep compound words based on automaton, robot, deception and con.
It's always been a shame that no stories from the multiverse have addressed why the faction symbols have Soundwave, Prowl, Bluestreak and Smokescreen's respective faces. Like a revelation that the Prowl 'mould' was the first of the Quintesson's production line of consumer goods. Or Megatron trying to draw a face for his revolution, continually stuffing it up and then getting Soundwave to pose for him.![]()
