For release in America, as a Target exclusive. (after losing ToysRUs as their outlet for Movie Masterpiece toys, Hasbro started using Entertainment Earth, but with their limited distribution (being just online) it looks like they managed to get another retailer to stock these, which should increase the sales of future Masterpiece, if this is not just a one-off exclusive for Target)
Hasbro debuted their latest figure from their Movie Masterpiece line of TRANSFORMERS figures – the MPM-10 Starscream! This Starscream figure is an authentic TRANSFORMERS collectible figure inspired by CAD files from the first theatrical films and stands at 11 inches tall in robot mode! MPM-10 Starscream will be available exclusively at Target.com and in stores on Sept. 1 of this year.
Ages 8 and Up/Approx. Retail Price $149.99/ Available 9/1/2020
And in China, it looks to have its release there in the same month.
Masterpiece Series MPM-10 Starscream! 50 points of articulation, die cast parts, highly posable hands and moveable mouth, missile and buzz saw arm attachments, and Gatling blaster accessory. Available September 2020.
