The Masterpiece line is a series of Transformers created by Takara to update a character's G1 toy with today's advanced engineering techniques. "Masterpiece" Transformers tend to be very expensive, with an average price of 10000 yen (roughly $80 at current conversion rates). Currently, the Masterpieces appear to be on a bi-yearly rotation, with a new being released in the spring or the fall.

MP-3 - Starscream
This toy is designed by mechanical designer Shoji Kawamori who had designed some of the original Diaclone toys, including F-15 Robo which would become Starscream and the rest of the seekers, he also famously designed the VF-1 Valkyries which Habsro recolored as Jetfire. It was designed to resemble a real-life jet hence the dark grey color scheme, there is a lot of kibble used to cover up the robot parts to form a streamlined fuselage such as the parts of the rear fuselage that hang off the hips like sheaths.
He comes with a non-transforming Megatron gun, as used several times in the show, and a stand that can support him in aircraft mode and robot mode (as he is very prone to falling over)
For the American release, Hasbro had recolored MP-3 based on his G1 toy design (with blue nosecone as opposed to grey like in the show), no changes were made to the engineering, however.

MP-11 - Starscream Coronation Version
This is a retool of MP-3 Starscream. This robot mode looks more like Starscream in the show, instead of looking like a real F-15 Eagle like MP-3 does. The aircraft mode is no longer streamlined due to the removal of a lot of the kibble, the tail fins are now part of the legs. The feet are completely remolded and viewable Jet engines also serve as heels for Starscream in robot mode, providing better balance. Starscream no longer has detachable missiles; instead, his weapons are attached to his arm (just like in the show), using ball joints, they can attach to the wings in aircraft mode, this allows you to transform Starscream without taking anything apart, not even the weapons.
MP-11 comes with new accessories such as a crown and a foldable cape, as seen in The Transformers: The Movie, although he lacks to stand that allows you to display him in aircaft mode.
