The first figure is a Black Rose Dragon figure, “a dragon based on a rose”, designed by Kenshi Andou.

The direction taken for this figure is to “make it more plant-like, and at the same time, make the base of the feathers and the neck part more armor-like”.

Additionally, since Galaxy-Eyes Tachyon Dragon is indeed an Xyz Monster, an additional accessory of Overlay Units/Xyz Materials is also in the works.
