Among the numerous items appearing in ”Kamen Rider Zero-One”, the one radiating a presence that is visibly power-type is the ”DX Punching Kong Progrise Key”. Speaking of Progrise Keys, they are important items symbolizing the world view in the show, but among them, Punching Kong has an impressive hearty image themed after a gorilla. If you are someone who likes ”Kamen Rider Vulcan's powerful forms”, it is an item that makes you want to picture the transformation scene from the show the moment you hold it in your hand. The set includes the main body of the Punching Kong Progrise Key and an instruction manual, and by not only playing with it alone but combining it with corresponding items sold separately, the range of play expands rapidly.

A big highlight of this item is that it can be linked with the separately sold ”DX AIMS Shotriser”. First, activate the Progrise Key and load it into the Shotriser. Furthermore, by transforming the key and pulling the trigger, you can enjoy transformation play into Kamen Rider Vulcan Punching Kong. The interesting point is that instead of just playing sounds and ending, there is a series of operations: ”activate”, ”load”, ”transform”, and ”pull the trigger”. Because you actually move your own hands to proceed through the steps up to transformation, it is an irresistible feature for people who want to play while pretending to be Vulcan.

The way to play with the Punching Kong Progrise Key is not limited to the Shotriser. It also supports the separately sold ”Hiden Zero-One Driver”, where after pressing the button on the key and touching it to the Driver, you can expand the main unit and load it into the belt. In other words, you can combine a single key with different transformation items. This kind of linked play is precisely one of the joys of collecting Progrise Keys. Since it makes you want to try thinking, ”I wonder what happens if I use this key with another item”, the ways to play naturally become richer as your collection grows.

You might think, ”Can't I play with it unless I have a compatible belt?”, but the Punching Kong Progrise Key can be enjoyed with just the main unit alone. Pressing the button activates the light-emitting and sound gimmicks, and expanding the main unit further transforms it into Key Mode. In a palm-sized item, toy-like fun such as sound, light, and transformation is packed inside. What I personally want to pay attention to is that it has a structure that makes you ”want to touch and play with it” rather than being a mere collectible item. In balancing the joy of displaying and viewing with the interest of actually operating it, I feel the charm unique to DX toys.

What is a Progrise Key in the first place? In the work's lore, they are defined as ”Data Activate Keys” that separate data accumulated in the Communication Satellite Zea into various abilities. Each has an animal motif and a unique ability set, and by loading it into a corresponding transformation belt or weapon, it is a mechanism that allows the use of the abilities of a ”Rider Model”, which is a data image of a biological species. That power relates not only to transforming into a Rider but also to strengthening special moves. Knowing these settings and then looking at the real key makes it feel like holding a ”futuristic device storing biological capabilities” rather than a small toy, which is an interesting aspect.

We must not forget the ”Rider Model” either. In the show, it appears during a Rider's transformation and not only guards the transformer, but depending on the Rider, it is also utilized for offense and defense in combat after transformation. Particularly in Zero-One's case, because the Rider Model was summoned to the ground from the Communication Satellite Zea during the transformation process, in the early stages, transforming indoors would result in breaking through the ceiling—a strangely physical occurrence despite being a futuristic system. Recalling such depictions seen prior to Episode 12, it is easy to see that the Progrise Key is not a mere transformation switch, but a device closely connected to the work's unique sci-fi lore. Something you notice while collecting Progrise Keys is the interest of their naming. The names are basically unified in a format combining ”-ing” with an English animal name, and ”Punching Kong” is also a name that makes you feel that rule. However, not all of them are simple present participles; there are also cases where the base form ”sting” or the noun ”lightning” is used. When paying attention to such detailed naming methods, the joy of comparing each key also increases. Precisely because the ability, animal, name, and transformation gimmick are tied together respectively, a unique sense of unity is likely created when lined up as a series.

The ”DX Punching Kong Progrise Key” not only allows you to enjoy transformation play into Kamen Rider Vulcan Punching Kong, but also includes multiple ways to enjoy within its small body, such as linking with the Hiden Zero-One Driver, standalone lighting and sound, and transformation into Key Mode. And if you delve into the lore of the show, it connects to the world view unique to ”Kamen Rider Zero-One”, such as the Communication Satellite Zea and Rider Models. Fun to play with, fun to collect, and even more interesting once you know the lore. For those who want to savor the strength typical of Punching Kong in their hands, it is a Progrise Key that makes you want to thoroughly try operating it.
