Makoto Aoki

She is the the inventor of the Copyroid, a dummy body in which a NetNavi may enter and walk the world as if they were human, and is distraught when her work, that was meant to bring humans and Navis closer together, is utilized by the Zoanoroids for their war, and works hard to stop them. She is Meijin’s ex-girlfriend, though it is hinted the two still have an interest in each other. (Source: The Mega Man Knowledge Base)
