>>7583062I don't know about Kotobukiya's current line, but the older ones could be, depending on the line and specific kit. Blox was a really damn modular line and pretty cool. The kits were, at their base, made of universal cube pieces which could be connected to each other, then things like limbs, armor, and weapons could be connected to the cubes. Blox were also made so they could be attached to regular Zoid kits.
