I'm putting together a post detailing everything we know about Build, so that might help. All I need to know is Blood Stark's transformation device.

The Transteam Gun.

Does anyone know the romanizations of the weapons?

Is it definitely the Gun? I seem to recall reading about him with the Blade, plus he is next to the blade in the scan.

Yes. Nightrogue and Bloodstalk both use the Transteam Gun to transform, but they both also share the Steam Blade as their weapon. They both have both.

They both transform with the gun and use the sword as their sidearm.

lol.

So does that mean his weapon is call the BeatClawser?

It's no surprise that Japan loves puns in any shape or form.

Those gimmick figures look interesting. They seem to have the torso as a front-to-back split, with the left side parts attached on the back half and the right side on the front. Not exactly elegant, but probably the best way they could've done it at that scale. I predict the head and waist articulation will be more limited than usual, but I just hope the front half isn't too fragile with that big hole in the chest area.

By the way, can anyone identify those two combos between NinninComic and KaizokuRessha?

Those are Fire Hedgehog and Lion Cleaner.
