Doofenshmirtz Portrait
Doctor Heinz Doofenshmirtz is the secondary antagonist of the show Phineas and Ferb. Doofenshmirtz is voiced by Dan Povenmire and created by Povenmire and Jeff "Swampy" Marsh. Doofenshmirtz first appeared in the pilot episode of the series and since then has appeared in every episode to date except "Isabella and the Temple of Sap". He is potrayed as somewhat of a stereotypical cold-war mad scientist. A routinely bumbling, incompetent and forgetful mad scientist, Doofenshmirtz is the primary villain of the series and the mastermind behind the B-Plot. This is not random. NOW it's random!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Sometimes he is successful and takes over the world usually in alternate timelines. This is due to him losing his toy train as a child.
