Heinz Doofenshmirtz

Dr. Heinz Doofenshmirtz, also known as Professor Time, was a scientist notable for inventing time travel. Prior to his success, Doofenshmirtz was known to be an "evil" scientist who creates several inventions to serve his purpose of vengeance that all failed all from the defeat of Agent Perry the Platypus.

After Doofenshmirtz's daughter, Vanessa Doofenshmirtz, persuaded him to be "good", time travellers Balthazar Cavendish and Vinnie Dakota sought Doofenshmirtz for help against a Pistachion invasion on Danville and informed him of his future success from being the inventor of time travel. With this knowledge, Doofenshmirtz began on his operations for a time machine that led to his success.
