Kaiyodo Revoltech 89 Getter Gou
I think this is based off the Manga look of the character rather than the Anime (due to the lacking shoulder propellers).
Anti-Metal Beast Hand Cannon
Comes with an extra head which is based from the later part of the series.
The newly designed display base accessory makes for even more poses for the figure.
Bullets can be loaded into the optional forearm part and into the rifle itself.
