When talking about ”Kamen Rider Build,” the existence of Ryuga Banjo and Kamen Rider Cross-Z cannot be omitted. And the item symbolizing that transformation is ”DX Cross-Z Dragon.” Such a Cross-Z Dragon has reappeared as ”SUPER BEST DX Cross-Z Dragon” wearing a new package. For people who thought, ”I wanted it back then, but couldn't get it,” or ”I want to collect transformation items once again,” it can be said to be truly a long-awaited opportunity. In the set, not only the Cross-Z Dragon main body, but also the Dragon Fullbottle is attached. From the moment you open the box, it is a combination that reminds you of Ryuga Banjo's and Cross-Z's active roles.

The real pleasure of this item is, after all, transformation play. If you set Cross-Z Dragon in the separately sold ”SUPER BEST Transformation Belt DX Build Driver” and rotate the lever, the belt emits light and the transformation sound is activated. You can enjoy the transformation sequence to Kamen Rider Cross-Z with your own hands. Precisely because there is a series of actions of attaching the item and then turning the lever, rather than just pressing a button, the point is that the feeling of ”transforming” becomes much deeper. If you already have the Build Driver, by adding Cross-Z Dragon, how to play expands, and you will be able to taste a transformation experience different from Build.

What in the world is Cross-Z Dragon in the first place? In the show, it appears as a dragon-type autonomous action mech developed by Sento Kiryu as a watchdog for Ryuga Banjo. Listening to only this setting, it sounds like a cute sidekick, but its abilities are surprisingly full-scale. When loaded with the Dragon Fullbottle, its functions are expanded, and it can emit blue flames from its mouth. What surprises even more is that it even possesses the ability to bite an opponent affected by poison, suck out that poison, and detoxify it. Because it is set not just as a ”dragon-type item used for transformation,” but as a mech that has an independent role in the world of the show, even when placed at hand, it has a presence different from a mere transformation part.

However, this Cross-Z Dragon is not necessarily omnipotent just because it is excellent. Rather, its character quality is quite intense. Because it makes BGM and cries reminiscent of a unique samba echo around, it is not at all suited for scenes where it wants to act secretly. Even though it is a high-performance mech that can spew blue flames and even detoxify, the part where it seems likely to assert its existence precisely when you want it to be quiet is so like Cross-Z Dragon. This gap between a ”cool dragon mech” and a ”strangely lively sidekick” is precisely one of the reasons love springs up in the show. When looking at the toy after knowing the setting, the interesting part is that it comes into view not as mere equipment, but as a single sidekick by Ryuga Banjo's side.

”SUPER BEST DX Cross-Z Dragon” is not an item just to play with by sounding transformation sounds. Combining the Dragon Fullbottle, attaching it to the Build Driver, and turning the lever. In that series of operations, the figure of Ryuga Banjo transforming into Kamen Rider Cross-Z overlaps naturally. On the other hand, in the show, it plays an active role as an autonomous action mech, and while possessing flame and detoxification abilities, it also has a unique side of potentially ruining stealth operations with lively sounds. Precisely because it is equipped not just with coolness, but even with an somehow lovable personality, it remains in memory. For people who like Cross-Z of course, and even for people who want to collect ”Kamen Rider Build” items once again, it is an item that vividly recalls the memories of the work.
