ALSO... the airplane transformer...
other transformers get beat up and wounded and all that, and yet the next scene they are back to tip top shape. the airplane never gets hurt or wounded but is perpetually all junked out. which makes me think... was he specifically designed to be all junked out? you get starscream who's an f-22 raptor, sideswipe is a corvette stingray concept, bumblebee is several different camaro's, drift was a bugatti veyron and the airplane dude, stratosphere, is just permanently a piece of smokey, rattly junk. the god of transformers, primus, must hate that guy
