Masterpiece

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.
