i rememver there was this transformers series when the good guys
will transform into cars. the cool thing is that when they
transform into a car, their head will transform into a human size
robot and drives the car. 
then their boss is this robot who can only transform into a giant
head. what's this gaint head for u ask? well, their spaceship cum
base can transform into a giant robot, that's where the boss will
transform and provide the head.
