Behind the Scenes
First Appearance:
  "Fungus Among Us"
Voiced by:
Dan Povenmire

Dr. Heinz Doofenshmirtz is a formerly-evil scientist who is revealed to be the past identity of Professor Time; the scientist famous for inventing time travel in the future. After his building is destroyed in the aftermath of the Pistashion invasion, he crashes on Milo's couch. 

He is voiced by Dan Povenmire


Doofenshmirtz doesn't initially believe he's destined to become professor Time and becomes a little overwhelmed by the amount of pressure he's under to save the world and follow his destiny.

Physical Appearance

Doofenshmirtz is a 6'2" tall man with a very long, pointed nose, blue eyes, and short, messy brown hair. He regularly wears a knee-length white lab coat over a black turtleneck sweater alongside a pair of plain grey pants with black shoes.

There are notable bags under his eyes, and he stands with a prominent slouch.

Professor Time

As Professor Time, Doofenshmirtz wears a long, dark purple tailcoat with a bright purple bow-tie over a purple and yellow dress shirt. His tailcoat has light yellow cuffs that match the yellow on his shirt, and he wears a pair of pants that are striped vertically with shades of purple.

His outfit is worn with a matching purple top hat that has a yellow band, worn with a pair of purple and grey goggles. He also wears a metal backpack with three lightbulb-like attachments on the top.


Doofenshmirtz was originally the main villain on Phineas and Ferb. In the summer that took place directly before Milo Murphy's law, Doofenshmirtz had been an evil scientist and owner of Doofenshmirtz Evil Incorporated. He wasn't so much evil in the traditional sense, rather he tended to be overly dramatic, eccentric, and generally clueless. He would constantly attempt to become ruler of "the entire Tri-State Area", but all of his plans more or less end up being thwarted by his nemesis, Perry the Platypus.

At the end of the summer, Doofenshmirtz was given a choice between hard time or community service. Choosing the latter, he became a high school science teacher at the beginning of the academic year ("Doof 101").

In a similar vein, once that summer ended, Doofenshmirtz gave up being evil and became an O.W.C.A. agent, classified as an ocelot due to his having been raised by ocelots during his youth ("Last Day of Summer", "O.W.C.A. Files").

Recent Events

In Missing Milo, Professor Time was brought up in conversation in 2175 and is revealed to be the person to invent time-travel. Milo commented that, whoever he was, he'd probably changed his name to 'Professor Time' for branding purposes.

In Fungus Among Us, during the Pistashions' second takeover of the Earth, Cavendish, Dakota, Milo, Diogee, and Orton go to 9297 Polly Parkway in an attempt to find Professor Time, only to find his former self as Doofenshmirtz.

In The Phineas and Ferb Effect, it is confirmed that fifteen years later, Doofenshmirtz will invent time travel and change his name to Professor Time for branding purposes. Doofenshmirtz travels with Orton Mahlson, Balthazar Cavendish, and Vinnie Dakota in an attempt to retrieve his favorite orange soda and to stop the Pistashion invasion before it starts. Professor Time himself appears at the end of the episode after Doof remembers to read Orton's memoirs. The Professor and Orton then travel back to 1955 to destroy Derek before he can implement his plan of replacing humankind with plants wearing rubber masks, thereby restoring the original timeline.


Perry the Platypus

PnFE 03

Doofenshmirtz and Perry the Platypus share a long history together, having been nemesis' before Doofenshmirtz gave up evil. The two of them are close, and while the other members of their group struggled to pass the time in the time stream, Doofenshmirtz and Perry quietly enjoyed a game of 'Go fish' with each other, playing by passing a single hot sauce packet back and forth between them.

Milo Murphy

Doofenshmirtz is on friendly terms with Milo and currently lives as a houseguest in the Murphy house. Upon finding out about Murphy's law, he points out how many things have gone wrong for him in his life, and jokes that they might be related because of it. Doofenshmirtz calls him 'pizza delivery kid' upon running into him again near the end of their adventure.


Doofenshmirtz was on good terms with Diogee from the beginning, having been long time accustomed to interacting with animal agents rather than other humans on a daily basis. He immediately took to conversing with the dog, much to the rest of the group's confusion, and even expressed doubt when they claimed he was just a regular dog.

Balthazar Cavendish and Vinnie Dakota


Initially, Doofenshmirtz doesn't believe them when they claim he's professor time and even becomes considerably weirded out when Cavendish idolizes him. While he was willing to help them save the world at their word, he continuously put his own needs first, which, combined with his tendency to make mistakes, caused Cavendish to eventually snap and express his disappointment. Rather than taking the blame, Doofenshmirtz blames the time travelers for putting such high expectations on him and points out the fact that they were asking too much of him.

After regaining his confidence in becoming Professor Time, Doofenshmirtz makes a powerful speech, much to Cavendish's glee. Professor Time then appears and greets Cavendish, who squeals in excitement.

Orton Mahlson

PnFE 02

Throughout the invasion, Doofenshmirtz and Orton share the unique experience of having to live up to the greatness of their future selves. When Orton approaches him to express this, Doofenshmirtz wrongly assumes that Orton had followed him away from the others with the intention of mocking him for failing so many times. Instead, he relates to what Orton was trying to say.

Upon making a speech and hearing Orton state that he's writing it into his memoir, Doofenshmirtz smiles and lets him know that he would read the memoir when it was published. This suddenly inspires him to remember to read the memoir as professor Time, and sure enough, Professor Time himself appears before them from the future, having remembered to read it. Doofenshmirtz' future self then invites Orton to save the world with him so that they can both live up to their destinies.

“I'm gonna be someone important in the future! Me! Who would have thought, right? Right?”
“Why are you talking to Milo's dog?”
“I'm sorry, I... Force of habit, I guess. Y-You mean he's not a, y'know, with the little hat, part of a secret organization. None of that?”
“No, he's just a dog.”
“Yeah... as far as you know.”
Doofenshmirtz and Vinnie Dakota[source]

“...It's not too much, is it?”
“Not as long as you can take us back in time to 1965, and get Orton his show back, and defeat the Pistashions, and save the world!”
“Yeah, no pressure. I'm gonna go back to talking to the dog.”
Doofenshmirtz and Milo Murphy[source]

“All right, anyone who built a time machine today, raise your hand. Yeah, I thought so! You get what you get, and you don't get upset!”

“No! I am Professor Time! And we are not out of time until I say so!”
