Magnum Polaris is a new-age Reploid created following the events of Mega Man ZX Genesis, and direct subordinate to Zero following the creation of the GR Maverick Hunters. He was among the first created via the use of new-age technology, and as such carries an extremely advanced method of attack. Despite having an arrogant disposition and often trading banter and insults with his superior, Magnum is a devoted to the cause of hunting down Mavericks through and through, and as such is one of Zero's most trusted allies. He often fights alongside and hangs out with Ferrum Catena, and has an attraction to Accipitri Siren.
