Phineas and Ferb

Phineas and Ferb is an American animated comedy-musical television series. Originally broadcast as a preview on August 17, 2007, and officially premiered on February 1, 2008 on Disney Channel, the series follows Phineas Flynn and his English stepbrother Ferb Fletcher^[1]on summer vacation. Every day, the boys embark on some grand new project, which annoys their controlling sister, Candace, who frequently tries to reveal their shenanigans to the boys' mother, Linda Flynn-Fletcher, and less frequently to their father, Lawrence Fletcher. 

charactors:
Phineas Flynn (voiced by Vincent Martella) Like other characters, his age is not mentioned. Phineas, along with his stepbrother Ferb Fletcher, star in the A-Plot of every episode. The series concerns Phineas 's attempts to avoid boredom by finding something new to do every day of the summer vacation. He does this with his less-talkative stepbrother Ferb,^[1] and often with many other neighborhood children. He is known to be very selfless and energetic. Phineas has many catch phrases like "Oh, there you are, Perry" or "Hey, Ferb! I know what we're going to do today!" and "Hey, where's Perry?"

.Ferb Fletcher (voiced by Thomas Sangster) is Phineas's green-haired, intelligent but laconic stepbrother from England and created byPhineas and Ferb co-founders Dan Povenmire and Jeff "Swampy" Marsh. He first appeared in the show's pilot episode, "Rollercoaster."

Ferb and his stepbrother Phineas Flynn spend their days during their summer vacation having fun. They are featured in every episode's A-Plotconstructing large scale inventions or taking part in other outlandish activities. Ferb, an engineering genius, allows Phineas to do most of the talking for the pair and is described as "more of a man of action," by Phineas, which makes him more of a plot device than a developed character. Ferb is more likely to sing than speak, but most often has a one-liner in the episodes. Ferb is named after a friend of the show's creators who was an expert on tools and, at times, stayed rather silent.^[7]

Candace Flynn, (voiced by Ashley Tisdale) is Phineas's fifteen-year-old older sister and Ferb's stepsister.^[8] She first appeared in the pilot episode along with the other main characters who star in the A-Plot in which she is usually the main antagonist. Candace does not approve of the inventions her brothers create, and in almost every episode she attempts to "bust her brothers" by showing their mom. Her best friend is Stacy Hirano; Candace also has an obvious crush on Jeremy Johnson, but she is oblivious to the fact he likes her back. As a character, she has received a positive critical acclaim, having appeared in other media such as video games.^[9][10]

Perry the Platypus (vocal effects by Dee Bradley Baker), a.k.a. Agent P, is Phineas and Ferb's pet platypus and first appeared along with a large portion of the main cast in the pilot episode "Rollercoaster." Perry is featured as the star of the B-Plot for all but one episode of the series alongside his arch-nemesis Dr. Heinz Doofenshmirtz. He is a primarily silent character, with the only noises being the occasional rattling of his bill. Perry is often referred to, incorrectly, by Ferb as "the only mammal that lays eggs."^[11]

Dr. Heinz Doofenshmirtz (voiced by Dan Povenmire) is a mad scientist appearing in all but one episode's B-Plots thus far. He is the father to teenage Vanessa Doofenshmirtz and is the head of his own company, Doofenshmirtz Evil Inc. Depending on the episode, Dr. Doofenshmirtz's main goal is to either destroy or rule the Tri-State Area which was suggested to him as a starting point before trying to take over the world.^[12]Routinely bumbling, incompetent, and forgetful, Doofenshmirtz's plans–always involving various gadgets and inventions–have been thwarted by Perry the Platypus, though, several schemes failed due to the doctor's own incompetence.
