Perhaps you could have a core robot and then lots of bits of other vehicles you can plug onto it to make it either one type of vehicle or a mixture of two or more types. Mix and match. Like Centurions, but with TF.
That's interesting. Like say we have a normal Decepticon who transforms into a tank, but there are also add on bits that can "fuze" to his tank and make it part jet or F1 racer? I think that would be cool if the parts can also attach to his robot mode as weapons, armor, power up bits.
I like that Duocon idea. Usually similar figures can only combine in one mode or the other, not both. That would be interesting.
That's actually a good idea. Myself? I think the only way a Classics Fuzor will work is to create a vehicle/animal hybrid, like the Transmetals. with vehicles, it won't work unles there's some believeable hybrid vehicle or "attack mode" (Like Tracks and his flight mode) or they're a triple changer.
