I guess starting with Go-Onger they have movie repaint/remolds like Engine Daishougun, Gosei Wonder, and FS-0O Frog. What'd Shinkenger have?

I lean toward Grand in the whole Grand/Ground thing, but the box and paperwork does say Ground on it. Then again, official romanizations can be wrong (like with Falcom's Ys series where there is a villain named Dulk Fukt [Dark Fact] and a character in Ys SEVEN whose name is officially romanized Krshe)

About the actual figures.. I know the BoA version is pretty close, but after actually having a DX Gosei Ground the differences are night and day in the plastic, joint, and paint quality.

The Kyoryu origami I guess, since that first appeared in the movie IIRC.

Roanstalker is mostly right, one of the last DX special release repaints was the Black & Gold Daibouken. There was however a Black & Gold Minipla Gekitouja release. And during Go-Ongers run there was a Black & White Police Deco Gunbiroh, as well ass a blue and white Speedor repaint named Skydor.

It seems though that there have also been several special lucky draw type releases such as a full chrome Engine Oh. But as far as standard Black & Gold repaint releases though the last was Ultimate Daibouken. It's a shame though because figures like Daikaioh, Gosei Ground & Ultimate, even Gokaioh would look great in B&G.

Out of all the configurations for Goseiger this is probably my favorite one. The design actually feels like it was designed with thought in mind, instead of just sticking a bunch of stuff on and calling it an upgrade... Not very cluttered and it does give me some nostalgic vibes with MMPR's Dragon Battle Mode.
