Yup. Likewise Kurokage and Zangetsu are both repaints of Gaim in-show with new helmets, and Bravo is a retooled, spiked Baron suit.

There's three main body suits, representing the three main styles and eras. Gridon also has Baron's faceplate characteristics like "COME ON" and the trumpet tunes, likewise Kurokage and Zangetsu have Gaim's.

It's how in Ryuki every Rider had the same base body with new helmets and torso flare.

And then we have Ryugen doing his own thing.

Meanwhile, back to the adoration...
