The only non-Optimus movie figure I can think of with those colors is Reverb. Or are we talking movies other than TF ones?
I kinda thought of team america, but the answer had been posted already. think you would have made it obvious had you drawn in some puppet lines.
Hold everything. I'm kinda glad I haven't started painting this guy yet because I just discovered the perfect use for this mold. Motherfucking Gobot Wrong Way
Hmmm... starts rubbing my chin... Just might work for Wrongway. if for no other reason than he's got a rotor on his chest.
Not to mention with the Tomahawk head, he'd have a visored helmet! Or maybe I could hunt down a Generations Powerdive for his head...
paint him like the team america copter in alt mode, then add wrong way details in bot mode, and name him the "AMERICAN WAY"
