Dr. Doofenshmirtz in Phineas and Ferb
Doofenshmirtz is shown as a clumsy, not-so-smart evil genius. He always tries to take over the "entire tri-state area." He uses weird machines he buys online. His main enemy is Perry the Platypus. Perry is a secret agent platypus who pretends to be a regular pet. Even though Doofenshmirtz calls himself a doctor, he actually bought his degree online.
His Evil Plans and Past
In most episodes, Doofenshmirtz comes up with an evil plan or invention. He often tells a "backstory" from his childhood. These stories show his tough childhood in Gimmelshtump, Drusselstein. His parents were not very kind, and his brother, Roger, was always favored. For example, his parents made him dress like a girl or be a lawn gnome.
Doofenshmirtz usually talks a lot to himself and Perry. His inventions often work only once before Perry destroys them. This usually helps get rid of Phineas and Ferb's big inventions. This stops their sister, Candace, from showing their mom what they built. Before becoming an evil scientist, Doofenshmirtz was a bratwurst salesman.
Doofenshmirtz's Successes
Even though he fails most of the time, Doofenshmirtz sometimes succeeds. In "Candace Disconnected," he built a "Pick 'Em Up-Inator." This machine successfully picked up his daughter from school very quickly. In Phineas and Ferb the Movie: Across the 2nd Dimension, he built an "Otherdimension-Inator." This allowed travel to other dimensions, with help from Phineas and Ferb.
In "Cranius Maximus," he used a "Key-Find-Inator" to steal the Key to the City. Perry couldn't stop him that time. One of his most famous successes was in "Phineas and Ferb Save Summer." He built an "inator" that used Jupiter's mass to move Earth. This made summer end early. He even briefly took over the Tri-State Area because of this.
Becoming a Good Guy
In the last episode, "Last Day of Summer," Doofenshmirtz built a "Tri-Governor's Mansion." He wanted to be the first Tri-Governor of the Tri-State Area. He used a "Do-Over-Inator" to create time loops. This helped him beat Perry and succeed in his plan. He even made a law stopping Perry from stopping him.
However, Doofenshmirtz learned that his daughter, Vanessa, wanted to join O.W.C.A. (Organisation Without a Cool Acronym). His new job was stopping her. He decided Vanessa's happiness was more important than being evil. So, he gave up his evil ways and changed for the better. After this, Doofenshmirtz also became a member of O.W.C.A.
Funny Running Gags
Dr. Doofenshmirtz is part of many funny running jokes in Phineas and Ferb.
- He always names his inventions with "inator" at the end.
- He only recognizes Perry when Perry is wearing his secret agent hat.
- Every time Doofenshmirtz appears, you hear his special jingle: "Doofenshmirtz Evil Incorporated." A quartet usually sings it.
- His meetings with Perry often start with Doofenshmirtz telling a story from his past. They usually end with him yelling, "Curse you, Perry the Platypus!"
- His plans often fail because he puts "self-destruct" buttons on almost everything he owns.
- People in Danville often think he is a pharmacist because he wears a white lab coat. This was even a big part of a Halloween episode called "Night of the Living Pharmacists."
Dr. Doofenshmirtz in Milo Murphy's Law
Dr. Doofenshmirtz first appeared at the end of the Milo Murphy's Law season finale. He became a regular character in the second season. In "The Phineas and Ferb Effect," he helped stop the Pistachions. After everything went back to normal, his building collapsed. So, Doofenshmirtz became Milo's houseguest and lived in the shed in the Murphys' garden.
He stopped being evil and tried to be a good person. But he often still caused trouble, usually with his "Inators." He later found out that O.W.C.A. paid Perry to watch him. This made Doofenshmirtz upset with Perry. He then looked for a new adventure friend. He became friends with Dakota, who also lost his partner, Cavendish. They started investigating Cavendish's disappearance together.
How Dr. Doofenshmirtz Was Created

When Jeff "Swampy" Marsh and Dan Povenmire worked on Rocko's Modern Life, they always added a song and an action scene. They wanted to do this in Phineas and Ferb. They created Perry the Platypus as a secret agent enemy. "Dr. Meddleshmirtz," which later became Doofenshmirtz, was created in a similar way.
All the main characters in the show were designed using simple shapes, like in old cartoons. Doofenshmirtz looks like an oval. The simple drawings made it easy for kids to copy them. Each character was designed to be easy to recognize, even from far away.
His Voice
Dan Povenmire, one of the show's creators, voices Doofenshmirtz. He describes the voice as "Eastern European." He first used this voice when he was fifteen, playing with his younger sister. His sister still asks him to do the voice often. When recording, Povenmire can easily make up new lines. The writers can change his lines, and he can still perform them well.
Doof's Daily Dirt Webseries
In 2013, Doofenshmirtz started his own YouTube channel and weekly video show called Doof's Daily Dirt. He would talk about popular internet trends and memes. However, he usually talked about them long after they were popular. He discussed things like Facebook, internet slang, and popular songs. He also started a Twitter account. The web series had 13 episodes and was later renewed for a second season. It ended when the main Phineas and Ferb show ended.
