Takara Tomy has posted new images of Masterpiece Shouki to its Transformers Twitter feed. These include a photo of the packaging for the figure suggesting it is packaged in vehicle mode (which makes sense given its more compact shape). We also get close ups of the figure showing its beautiful detailing and hinting at its complexity.
Shouki was featured in the Transformers: Headmasters series as the leader of the team known as the Trainbots. The team could combine to form the Combiner, Raiden. This figure marks the first in a series of Trainbots making this the first official Masterpiece Combiner! Shouki is currently available for preorder via BigBadToyStore and Entertainment Earth and is due to ship in the June/July 2022 time frame. Below I've included the product description and new images below with the older stock photos for reference.
Product Description (from Takara Tomy Mall and translated via Google Translate):
Transformers railway theme is commercialized! "Trainbot's Showki", which was active in the TV anime "Transformers: The Headmasters", is now available in the new series "MPG"! "MPG" is an abbreviation for Masterpiece G, which means GATTAI, GIANT, and GREAT.
The first from the new Transformers series "MPG", the Tokaido Shinkansen 0 series is completely transformed into a robot! Since it is a fully poseable specification, you can enjoy reproducing the poses in the play. You can enjoy the display on the attached rail, and other weapons, seats, and chest parts for Leiden are included. In addition, it is a triple change specification, and it can be transformed into the chest part of "Leiden"! You can complete "Leiden" by combining it with 5 types of trainbots to be released in the future.
