After picking up Sunstorm from Amazon Japan, I decided to get Starscream MP-03 USA Edition as well. Different in color from the actual US release and original MP-03 Japanese release, his vehicle mode’s realism really sold me.
He can’t wear the shoulder pads properly, but he was a lot easier for me to transform than Sunstorm.
I really dig the stand, paintjob and extra equipment. However, it doesn’t come with a trading card, pretty box, or pretty instruction manual. He might be slightly lower than Sunstorm as well, and his face changes, otherwise they are both very similar.
Except of course for the realism of Starscream’s vehicle mode, and Sunstorms sturdy robot mode is smoother. The plastic seems a little worse cut on Starscream, but its probably Hasbro’s fault.
