Just stop eating, Die. Food is such an expensive product, and what do you have to show for it? Nothing. (Please don't do this).

In actual helpful info, the three types of SHODO do, in fact, work together - the letters on the end are more in terms of rebrands and spin-off lines than any major differences. Basically, we have

SHODO-VS: The first line, ended a couple of years ago. Called as such because they included at least one villain per wave, such as Doras, Tigerroid, and other less memorable ones. They managed to do close to every Showa rider, plus a few others. Chase figures were used occasionally, so if you ever go looking and see a Kabuto box marked as "Dark Kabuto" for silgithy more money, that's why. It was eventually 'upgraded' (aka given a new name to refresh sales I imagine) to...

SHODO-X: The current 'mainline' of SHODO, focusing primarily on main Riders and their bikes. They've gone and redone pretty much every Showa Rider with their bike, which do look better, as well as continuing the Heisei series _ think, minus Den-O, you can have all main riders up to OOO hanging around together, and they all scale fine!

SHODO-O, short for SHODO-Outsider, started the most recent, and focuses on building around the main SHODO-X range - villains, secondaries, popular characters, etc. I think they cost like 100 yen more than your typical SHODO-X, and so have slightly better paint and accessories? I've not actually bought any. I also haven't made a wiki page on them, so I Know what I'm doing today. I *do* know they scale perfectly with normal SHODO, so if you manage to pick up, say, Faiz Kaixa and best-Rider, they'll look great together.

As for buying them, ummm Mandarake? Idk, I don't know anything outside of that. The problem is that, unlike SO-DO, they don't do a "buy only one of everything" set, only an "Assortment of 12", so unless you can split them up, you have to hope the second-hand market will provide. Hope this helps!
