Bandai has done a pretty good job with their D.C. reboot, retooling the classic Go Nagai SOC to a more sleek, anime-accurate depiction, also removing some aesthetic problems from the older releases, like very visible seam lines or screw holes on the back side. The feedback from fans have been lukewarm with the D.C. Mazingers (complains about being too skinny), and Getter-1 (ugly grey color), but Grendizer is getting praises in every aspect. The head sculpt, imo, is the best Grendizer head I've seen on a diecast toy. Also, he is heftier than his predecessors. The Spazer is released separately.
