Another new form, Key/Dragon and a closer look at Kamen Rider Close

I like to see it as after Fourze it got subtle cause they sure aint gonna have a rider fidget with 8 to 9 items to change into synthetic leather.

Enjoying the W influences, it makes Build seem like a classic rider with a stream lined design, can't say much about secondary modes need a bit more of them

In my opinion, Build's unique main points is on his different eyes designs and different colors. Hmm.....I really curious if Build can use two same Full Bottles in his Driver.

The OOO net movies bring up a point about this. It wouldn't show the gimmick nearly as well, which is why we only got W Cyclone Cyclone, JokerJoker and Kamen Rider Joker outside of the show. For the toys it might not be possible, as say, the Switches only fit in their respective places

Hmm....maybe left Full Bottle and right Full Bottle will be has some difference like right Gaia Memory has silver connector and left Gaia Memory has gold connector.

There's always a way to continue this trend I guess.
I probably deserve that.

I find it interesting that Close is basically Dragon/Dragon with armour on top of that. Perhaps he uses a Full Bottle that 'draws out the true potential of the other', or something, seeing as he uses the Build Driver according to Crane Joe.

Maybe Close has symmetrical design because he already has full potential.

That...doesn't make sense? Unless he only uses Dragon (and only using one gives you a symmetrical form), or he uses two dragons (unlikely, because then they'd have to give you two to access his sounds, and the listings don't mention that) then there has to be something else he can use with the Build Driver to give him two Dragon halves.
