He is the head of the O.W.C.A. (Organization Without a Cool Acronym) Department and Perry the Platypus' boss along with Agent D. He usually appears on a giant screen giving Perry instructions for his next mission to stop Dr. Heinz Doofenshmirtz's endless attempts to take over the Tri-State Area, as well as having his other agents to stop the evil villains of L.O.V.E.M.U.F.F.I.N. (led by the infamous Aloyse Von Roddenstein) on their tracks. His uniform prominently features the initials "MM." He has a monobrow and wears a toupee. Just like Doofenshmirtz, he has appeared in every episode of the series to date except, "Isabella and the Temple of Sap."
