This armor's main difference from its predecessors is its sheer size; the torso and shoulders in particular are massive. Its development, starting from scratch, resulted mainly from Stark's fear that an innate factor had resulted in his previous armor developing sentience. Its appearance also differed markedly from the Sentient Armor, perhaps to make it seem as different as possible: it possessed a circular chest beam, a greatly altered overall configuration (including many "industrial-style" details such as external tubing, earning this suit the ignoble nickname "udder armor") and a restyled helmet.
