Heinz Doofenshmirtz is the mad scientist from Disney’s Phineas and Ferb. He’s a scientific genius, but clumsy and forgetful. The names of his inventions most of the time end with “-inator” and are often the reason why Phineas and Ferb don’t get busted because they remove their inventions before their mom finds out about them. The hardships of his past are the motivation behind his evil schemes. Heinz despises almost everything now, but he’s not evil at heart. Although he always fights Agent P, he also considers Perry the Platypus as his best friend. Doctor Doofenshmirtz ex wife is Charlene Doofenshmirtz and they have joint custody of their daughter, Vansessa.
