Enter Action Square. The pixelated pioneer, the polygonal protagonist, the rectangular rogue, the equal-sided exemplar, the boxlike big cheese, the four-sided foe-conquerer, the equiangular entrepreneur, the quadrilateral Christ figure, the squarish swashbuckler, the all-sides-are-the-same-length adventurer, the geometric globetrotter, the parallelogram prima donna, the vector vanquisher. And he's green to boot.
