Hmm...bottle body is number 1 and bottle cap is number 0 so yeah...number 10 :D

Some Geed and Kyuranger stuff's here too but we see the Drill Crusher and World Driver (Was that name fake? I forget) stuff too

So Build's identity could possibly be genius scientist Sento Kiryu based on these notes


Also thinking about it now I think the belt is called the Whirl Driver and not world driver since the content of the bottles are whirled to form Build.

I'm more interested in the drill. So refreshing for a base form weapon tbh

The last sketch and the most recent listings called it the Buildriver/Build Driver.

My bad, ignore what I said. Carry on. :lolol

Descriptions of the forms:

*RabbitTank has a spring on his left leg, which enables his high-jumping powers.

*GorillaMond has a gigantic right arm & a crystal left eye.

*HawkGatling uses a gatling gun, unsurprising.

*NinNinComic has eyes based on manga designs; one is a shuriken & one is crescent-moon shaped. This form is supposedly purple & yellow.

Assuming the most recent drawings and rumors are accurate, I'm getting more and more curious about the "Best match" thing. Something I noticed on the (let's presume accurate) bottle designs is that the bit at the top of each is blended with the other. That is, the Rabbit bottle has Tank on it, and the Tank bottle has Rabbit.

With OOO and W, the gimmick involved the ability to make any combination with the given elements. I don't think Build is going to do that. The blended suit design makes it look like only specific elements mix together... thus, the "best match" thing. So... kind of like alchemy, despite the gears?

We finally have something.

Please keep a grain of salt while waiting for a source.

Awesome look.
