My vote goes to Starscream:
* he can't look left or right, due to those shoulders vent things
* he'd have to go sideways through all except the widest doors due to his wings.
* his null ray arm cannons stretch out beyond the length of his arms, so they must do nothing but knock **** over.
* his hip kibble must have made sitting down a mission.
Poor Screamer, normal life must have been a pain
