In Mother 3.5, PROJECT DARKDRAGON is one of the major plot points, leading up to the climactic scene. It was the ultimate weapon of the Three-Mile Army before their untimely destruction at the hands of some unnamed enemy army. They never got the chance to unleash PROJECT DARKDRAGON during their time. However, it was kept intact thanks to the Seven Needles. Porky Minch learned about PROJECT DARKDRAGON, having travelled to every time in the past and made it his mission during his time in the Nowhere Islands to see the project through to its end.
