(Like most topics around here. This heavily leans on G1 and IDW, but I think this extends to all shows) Are the Transformers really what they turn into, or is that a shell built around and plugged into a 'core-alt-mode' And how far does that shell change and affect this core-alt-mode? Does OptimusPrime turn into a Freightliner FL86 truck, period. OR! Is he some sort of spinning engine rotor which is best used attaching wheels too. It's just the current design he sticks with; wheels and truck chassis. And I don't mean BumbleBee's core mode is a 'car' he wasn't a car on cybertron. I mean it's something more basic, like a simple rotational motor, or energy producer, or magnetic coil. Which are just most common used for cars, guns, and jet modes. The seekers are famous for turning into tetra jets, presumably something that doesn't need air dynamic to fly. On earth, they're jet shaped but are they jets? If you ripped their wings off would they still be able to fly (assuming what ever makes them fly isn't in their wings) Can the seekers take any shape any form but always have to fly? Megatron has been a gun and a tank and a jet in IDW. Is his core-alt-mode some sort of energy producer? As gun or tank, these forms just projects the energy outwards as a weapon. They just tacted on threads in tank mode. And as a jet he uses energy producer as thrust. In IDW when they were getting ride of the disposable classes. Why not force them to turn into something useful? Unless they had limits? Personally I like the idea of a core-alt-mode. Make Functionism in IDW work. Would explain why some characters alt modes act so differently between same alt modes. Why are some car-bots so much faster? How Megatron-tank and Warpath-tank seem to be on to very different firepower levels. Maybe because their using two different core alt mode to reach the same vehicle. Why all bot just don't pick a flying alt mode. And why poor Ratbat didn't pick some better forms. It's the one unchangeable aspect of a bot. Maybe directly affected to the spark. What do you guys think?
