In Phineas and Ferb, Dr. Doofenshmirtz is an evil scientist who wants to use his machines to take over the Tri-State Area. He says he is “an evil scientist, not a mad scientist”. His nemesis Perry the Platypus stops his evil plans every day. Dr. Doofenshmirtz also has a lot of bad luck and says the reason he loses every time is because he has “poor planning skills”. Doofenshmirtz also gives almost every machine he builds a name ending with “inator”. Even though he calls himself evil and is the villain of the show, he has some good traits. For instance, he really does love his daughter Vanessa.
