|Dr Heinz Doofenshmirtz|
Dr. Heinz Doofenshmirtz (voiced by Dan Povenmire) is a mad scientist who is the secondary antagonist of the series, appearing in all but one episode's B-Plots thus far. He is the father to teenage Vanessa Doofenshmirtz and is the head of his own company, Doofenshmirtz Evil Inc. Depending on the episode, Dr. Doofenshmirtz's main goal is to either destroy or rule the Tri-State Area which was suggested to him as a starting point before trying to take over the world. Routinely bumbling, incompetent, and forgetful, Doofenshmirtz's plans–always involving various gadgets and inventions–have been thwarted by Perry the Platypus. After most defeats, he shouts his catchphrase, "Curse you, Perry the Platypus!" His first invention as a child was simply called "Inator" which led to his modern contraptions usually ending with the suffix of the same name.
