Introducing the "Hayate Immelmann's VF-31J Siegfried"! This model combines high quality with ease of assembly thanks to its three-stage interchangeable transformation and insert molding, a first for the series!
The "three-stage interchangeable transformation (shortcut change)" system simplifies the transformation sequence by using some interchangeable parts. It achieves the ease of assembly, wide range of motion, and refined forms of each form, all unique to the HG series.
By incorporating interchangeable parts into some of the transformation mechanism, the transformation sequence is simplified. Easily transforms into Battroid, Gerwalk, and Fighter.
The "three-stage interchangeable transformation (shortcut change)" system allows for each form to be faithfully recreated from the original design.
By eliminating complex structures and providing optimal articulation points that are conscious of posing, a new level of mobility is achieved.
This is the first HG Macross plastic model series to feature "insert molding." Even complex color-coded areas can be reproduced simply by separating the parts, achieving both high quality and ease of assembly.
The container unit can be stored by replacing parts.
The minigun pod has a movable axis and can be deployed forward.
In addition to two knives, it comes with two pilot figures, a Freyja Wion figure, and a multi-drone-type base.
Expressive hand parts are included, allowing for a variety of poses.
The canopy, made with polarized molding, can be opened and closed.
