Built to Rule!
Hasbro's Built to Rule toyline is a line of building block sets that, when assembled, resemble toys from some of Hasbro's other toylines, like GI Joe and Transformers. The building blocks are compatible with the Lego or Mega Blocks brands of building blocks.
The Transformers Built to Rule Toyline consisted of an Armada line, which recieved a public release, and a short lived Energon line, which only had a limited, test market release in Cincinnati, OH.
Both lines were relatively the same, a kit that consisted of a core piece, to which molded building bricks were connected to resemble either a vehicle mode, or a robot mode. Unlike other Transformers toylines, Built to Rule figures didn't transform, but had to be deconstructed and reconstructed to change between molds.
