or are you gonna argue that W physically mutates and grows a gun on his chest?
I'm down with that.
Technorganic stuff isn't that of the question now-a-days in the realm of Sci-Fi kid shows...or any other sci-fi show for that matter. Worked for the Trigger dopant anyway...and Arms dopant...Commander dopant. There was alot of heavy ordinance in W.
W is a dopant in my mind, just one born from filtered gaia memories. That is also why they could fuse physicaly when they became Extreme, why Accel could turn into a motor bike, and skull could shoot a massive, energy skull from his chest. I'll even go as far as to argue the prisim beaker was technorganic as were the memories. Plus crazy gaia memory energy data bullshit that I love so much. Then again that is also why KR CORE happened...man I really don't like CORE...oh well.
I also liked the idea of Ichigo and Nigo wearing armor so they could conceal themselves as normal humans, while also getting the defense the suits imparted to them. Cyborgs or not, they could still be damaged, especially if they still had organic components in their bodies. The armor allows them to hide their human forms so they could be used as shocker agents in public only transforming when it was stime to kill.
I'm in my only little camp where Shocker inhumanoids were not only cybernetically altered, but also biologically. That is why so many shocker cyborgs looks..well...organic. They improved what they could through genetic alteration, and then used cybernetics to replace what they couldn't.
The double riders might be the exception to this or a more advanced altered human that didn't have significant physical mutations from their alteration. This may also explain why so few riders were developed: expense. Even shocker must have limits to what they can do financially.
Of course if this is the case at all, then it means the movie had more retcon then we thought. Would that count as retcon?
My prove...if you can call it that, lies with the Kamen Rider Gaia manga. The hero of said manga started out looking like a more organic Kamen Rider style Kaijin before refining his metamorphosis into armor.
In the Skullman manga (the newer one from the 90's), a Kamen Rider style character appeared with a smiliar issue as Gaia that was eventually resolved with him in rider armor.
Long story short, it is probably armor, but that doesn't mean it can't be technorganic armor produced from their bodies that can be removed like any other suit.
By the way, while Ishinomori didn't produce that second skullman manga himself he did pass the torch to the mangaka who did and gave him some data on what he wanted. Not sure about Gaia though.
