While the Transformers Americans know saw a sharp decline after 1986, they were just getting started in Japan, and GOD GINRAI was the Japan-Exclusive Transformer that truly started it all! Victory Saber, Brave J-Decker, and Brave Great Goldran are all explicit updates of this updated Optimus Prime design, and Masterpiece Ginrai, Masterpiece Super Ginrai, and Masterpiece God Bomber are modern interpretations of it.
And (my apologies) it's pronounced, "Jinrai," not "Ginrai".
