Dr. Heinz Doofenshmirtz is the main antagonist of the Disney Channel animated series Phineas and Ferb; he is a mad scientist and head of Doofenshmirtz Evil Incorporated. He tends not to be evil in the traditional sense, but rather overly dramatic, eccentric and generally clueless. He constantly attempts to wreak havoc across or take over "the entire Tri-State Area", but all of his plans tend to be thwarted either by his nemesis, Perry the Platypus, or by his own incompetence. Doofenshmirtz would eventually give up his villainous ways and reform at the end of the series, and later become a regular in the second season of Milo Murphy's Law, in which it is revealed that he will eventually create time travel under the alias "Professor Time".
