I got to thinking today about how Wheelie described himself as a "drone", but seemingly still has the same level of sentience as a typical Transformer. Scorponok is another character described as a drone unit, this time as a symbiotic outgrowth of Blackout; and Ravage, likewise, is described as "part and parcel" of Soundwave. These two display "average" levels of intelligence and problem solving ability, albeit with more feral savagery mixed-in. Essentially they are portrayed as the Transformer equivalent of animals, but do not at any time appear "stupid" or "mindless". (Not to say that animals are stupid or mindless of course...) What exactly constitutes a Transformer "Drone"? What's the difference between a drone and a normal Transformer? Do drones hold less standing in Transformer society? Are they born like other Transformers or are they built especially for whatever they're intended to do (Wheelie said he was a "Salvage and Scrap" drone)?
