I'm not talking about the R.I.D series, but rather the entire concept across most of the lines/universes. Usual disclaimer: Yes, I know it's just a cartoon and just a kid's toyline, etc etc yadda yadda. And I know that the Ark "made a mistake" in taking vehicles for the dominant lifeform. Shaddap. Most of the lines of Transformers are NOT, contrary to the tagline, in disguise at all. BeastWars were OK at it for their time, but would not be in today's world. Think about it - your requirements are to take on a disguise that: a) can conceal your mass (we are NOT talking mass shifting here, if they could do that then the whole thing is moot as they could just shrink into specks and zoom around like that - no one would see them at all). b) is commonly seen in modern society, and not normally attacked by human military. c) is freely mobile. Take item b - a tank can move, but it does not properly disguise the robot since any military would surely chase and attack an errant, wandering tank. Most of the Decepticons fail the disguise test. Apart from Megs, Soundwave, Shockwave etc with their mass-shifting issues, the seekers also have problems with disguise. Mysterious F-15 fighers are not generally accepted as free to roam the skies without challenge from the military - they'd show up on radar and attacks would be launched. The only way the seekers could move about in disguise would be if they are invisible to radar - in which case visibly appearing as a human-built jet is moot, since they'd be attacked on sight anyway. The Constructicons and other common vehicles stand the best chance, especially if they have tinted windows or fake driver decoys. The Predacons make no sense - either they are the size of a cow (and thus a robot of only about 12 feet tall), or they are giant animals. And any animal, giant or no, isn't generally allowed to wander freely in today's society. A grouping of a lion, panther, bull, rhino and hawk wouldn't exactly go unnoticed. And I'm not even mentioning the whole "mechanical and primarily red and orange in color" part. So for the Autobots; Prime and most of the cars are OK. Again, they'd need decoy drivers or tinting to maintain disguise. Ignore the mass-shifters like Blaster and Perceptor. The Arielbots and Jetfire would run into the same problems as the seekers - rogue airplanes are not accepted in today's skies. The dinobots would be MORE noticeable "in disguise" than in robot form, being giant silver mechanical extinct species. The Insecticons require mass-shifting, otherwise they are giant mechanical insects and as much in "disguise" as the dinobots. Astrotrain and Blitzwing get no disguise from any of thier 3 modes: tanks, jets, and shuttles are not generally allowed to roam freely. Neither are trains, let alone taking into account the limitations of tracks to run on ("Megatron! I can't join the battle, these tracks go to Boston! Byyyeeeeeee!"). In 1986 the "disguises" became even more futile. Most of the TF's are no longer even trying, instead maintaining non-earth alt modes like space jets (Cyclonus, Scourge) and strange wheeled vehicles that never sold well to humans (flame-decaled camper vans from hell, spacecars, etc). A theory also arose among the 'bots that humans wouldn't notice entire cities appearing and disappearing all over the globe (Trypticon, Fort Max, Metroplex, Omega Supreme!). Humanity by this time was just glad to no longer be dodging giant mechanical insects and dinos, plus we had started drinking heavily. The Technobots aren't even trying. Skylinx makes no sense at all in alt mode, being some kind of base + shuttle/airliner. Yes, for super intelligent robots, they really aren't even as good at disguise as Dana Carvey. Fortunately, there are 2 things that make it all better: 1) They make GREAT toys. 2) The whole thing can be explained by giving each robot a simple "S.E.P." field generator. Brownie points to the first one to explain this. 2nd Disclaimer: This entire post is tongue-in-cheek and meant to spark a fun discussion. That is all. Please don't hurt me, I swear I'm not Michael Bay.
