Massive, quiet, and extremely protective of his home and its inhabitants, METROPLEX is a kind, intelligent leader of his people. His huge size and quiet ways mask a swift intelligence capable of analyzing the most sophisticated difficulties and arriving at a course of action in seconds, though some have made the mistake of thinking him slow and stupid. He was, at one time, an eager and hideously dangerous warrior who developed his soft-spoken and carefully considered demeanor in an attempt to leave that part of himself behind. Because of this, METROPLEX is slow to anger, but when he converts to combat mode he becomes one of the most fearsome opponents any TRANSFORMER has ever faced.
