Fireside Girls The Fireside Girls are a group of ten
girl scout-like girls led by Isabella in troop 46231. Isabella and the other Fireside Girls usually help Phineas and Ferb in their projects which, in turn, are at times created to help the Fireside Girls with a humanitarian cause. Other members of the troop: • '''''' (voiced by
Ariel Winter) wears glasses and has short auburn hair. She is the second in command in the troop and the first (besides Isabella) who had been addressed by name. • '''''' (voiced by
Cymphonique Miller (Seasons 1–2),
Diamond White (Season 2–Present),
Dana Davis (as a teenager in "Act Your Age")) has dark skin and black hair. • '''''' (voiced by

Dannah Phirman (as a teenager in "Act Your Age")) has curly, brown hair and freckles. • '''''' (voiced by
Madison Pettis) has straight, brown hair. She is the second member of the troop to be addressed by name, and the first to have been given a last name as well. • '''''' (voiced by
Tiffany Espensen (seasons 1–2),
Michaela Zee (season 3–Present), Although she does not like
dog food, Pinky will eat just about anything–especially her favorite; grilled cheese sandwiches (as seen in the episode "Journey to the Center of Candace") and even inedible objects, having once accidentally swallowed Isabella's Fireside Girl sash. Pinky always shakes as an ongoing joke about the behavior of other Chihuahuas. She first appeared in the episode, "Journey to the Center of Candace," where Pinky plays a major role, as Phineas and Ferb shrink themselves (as well as a submarine) to miniature proportions to go inside Pinky to retrieve Isabella's sash. However, Pinky is distracted just before she can eat the sandwich by a black cat, and later Candace dwells upon the sandwich, unaware that Phineas and Ferb are inside it, and Phineas and Ferb are then swallowed, unaware that they are in the wrong body.
Charlene Doofenshmirtz Charlene Doofenshmirtz (voiced by
Allison Janney) is the former wife of Dr. Heinz Doofenshmirtz and shares custody of their daughter, Vanessa. Unaware of Dr. Doofenshmirtz's "evil" side, and in fact saying she does not believe someone can ever be truly evil, she divorced him due to a lack of common interests and having different life-goals. She is very wealthy and gives her ex-husband a large allowance each month. She is sometimes called by Vanessa who tries to "bust" her father, but to no avail. Charlene and Linda Flynn-Fletcher have been paired up in a cooking class owned by Chef Pierre and in "I Scream, You Scream" were distracted by both Candace and Vanessa at the same time. Despite being divorced with Doof, she still goes to Doofenshmirtz family reunions claiming that she "kept the name," as seen in "Thaddeus and Thor." However, in the episode "
Tales From the Resistance: Back to the 2nd Dimension" (the episode sequel to the 2011 TV film,
"Phineas and Ferb: Across the 2nd Dimension"), it is shown that there is an alternate reality version of Charlene Doofenshmirtz. It turns out that 2nd Charlene is still married to 2nd Doof and actually shares much of his evil personality, and that their divorce was just a ruse to gain financial advantages during 2nd Doof's reign (such as receiving coupon mail, putting up junk yard sales, and going on separate vacation trips).
Suzy Johnson Suzy Johnson (voiced by
Kari Wahlgren), known as Little Suzy Johnson, is Jeremy's little sister. She has a high-pitched squeaky voice and appears very sweet and innocent. However, she is actually very spoiled and manipulative and very possessive over Jeremy, once telling Candace (who she hates), "There is only one girl in Jeremy's life", and thus will do anything to keep Candace away from her brother.
Grandpa Clyde and Grandma Betty Jo Grandpa Clyde Flynn and Grandma Betty Jo Flynn (voiced by
Barry Bostwick and
Caroline Rhea respectively) are Linda's parents, Phineas and Candace's maternal grandparents, Lawrence's -in-laws, and Ferb's step-grandparents. Every summer, they invite the family along with many neighborhood kids to a lakehouse which Phineas calls, "Camp P&F". Though they are very old, they often participate in the kids' capers. Grandpa Clyde, like Phineas and Ferb, has a great sense of mechanics, as seen in "Crack That Whip!" Betty Jo is also shown in the same episode to have a fierce rivalry with Edna Hildagard, Jeremy and Suzy's grandmother.
Grandpa Reginald and Grandma Winifred Grandpa Reginald Fletcher and Grandma Winifred Fletcher (voiced by
Malcolm McDowell and
Jane Carr) are Lawrence's parents, Ferb's paternal grandparents, Phineas and Candace's step grandparents, and Linda Flynn-Fletcher's -in-laws who reside in the United Kingdom. Reginald used to be a daredevil known as the Flying Fishmonger.
Roger Doofenshmirtz Roger Doofenshmirtz (voiced by
John O'Hurley) is mayor of Danville and Dr. Heinz Doofenshmirtz's younger brother. Heinz often states angrily that Roger is their mother's favorite son, and even wrote a song about it, "My Goody Two-Shoes Brother". In "Tree to Get Ready", Roger states that he is "the most handsome and charming man in the tri-state area". This enrages Doof a lot, who is convinced to use his latest -inator, the Poop-inator, to hypnotize the tri-state area pigeons into raining feces on Roger during his speech, when he receives the
Key To The City.
Irving Du Bois Irving Du Bois (voiced by
Jack McBrayer) is Phineas' and Ferb's self-proclaimed biggest fan. He always carries a scrapbook that he filled with images and souvenirs from Phineas and Ferb's big ideas as well as a strand of
Ferb's hair. Irving has an older brother Albert, who is self-nicknamed 'The Truth Detector.'
Django Brown Django Brown (voiced by
Alec Holden) is a good friend of
Phineas and
Ferb. Django is the son of the artist Beppo Brown from "Oil on Candace," who is famous for his work in making giant creations, from refrigerators to dental floss. He is named after co-creator Jeff "Swampy" Marsh's son, Django Marsh, who voices minor characters on the show.
Admiral Acronym Admiral Wanda Acronym (voiced by
Jane Leeves) is one of the heads of the O.W.C.A. (Organization Without a Cool Acronym) Department and Pinky the Chihuahua's boss. Just like Major Monogram, she usually appears on a giant screen giving Pinky instructions for his next mission to stop Professor Poofenplotz's endless attempts to take over the world. Also, just like Monogram (who has an unpaid intern named Carl), Adrimal Acronym has her own unpaid intern named Carla, who bears some similar resemblances to Carl.
Professor Poofenplotz Professor Esmeralda Poofenplotz (voiced by
Amanda Plummer) is an old mad scientist and the nemesis of Agent Pinky, Isabella's pet Chihuahua. She is known for her silly attempts for worldwide domination. Her known schemes so far involve replacing handbags, stealing royal jelly, and searching for strong hairspray (her favorite is "Stiff Beauty" hairspray, which originally was only used by clowns). Needless to say, because of her somewhat arrogant personality, Poofenplotz has failed to know about the flaws of her schemes. And because of that, it has allowed Pinky to defeat her in return, leaving an humiliated Poofenplotz to yell out, "Curse you, Pinky the Chihuahua!!", similar to how Heinz Doofenshmirtz says whenever his plans get foiled by Perry the Platypus.
Love Händel Love Händel is a rock band idolized by many in the Danville tri-state area, first seen in the episode, "Dude, We're Gettin' the Band Back Together!" Lawrence Fletcher and Linda Flynn shared their first kiss at a Love Händel concert. Shortly afterward, plagued by infighting caused by the pressures of a dwindling fanbase, Love Händel split up. Lead Singer
Danny (voiced by
Jaret Reddick) became the owner of Danny's Music Shop. Bass Player
Bobbi Fabulous (voiced by
Carlos Alazraqui) became the owner of Bobbi's Fashion Salon and Linda's hairdresser.
Sherman "Swampy" (voiced by
Steve Zahn) ended up working at the Danville Public Library, believing he had lost his sense of rhythm. Eventually, all three members are convinced to reunite for a concert in the Flynn/Fletcher's backyard, in which they sing their hit song, "You Snuck Your Way Right into My Heart." Love Handel occasionally reappears in other episodes and in the
movie where they sing their songs. The band also made appearances in episodes of ''
Milo Murphy's Law and Hamster and Gretel''.
Monty Monogram Monty Monogram (voiced by
Seth Green) is Major Monogram's son and has been working in O.W.C.A. since "Minor Monogram". Vanessa Doofenshmirtz seems to become interested in him after she broke up with Johnny, and it is possible that he is slightly interested in her too, because he winks at her before leaving. They have coffee together in "Sipping with the Enemy", at which point they apparently begin to date one another. In "Minor Monogram", he has recently graduated from the "High School Without a Cool Acronym" (H.S.W.C.A.) and he really wants to fight evil following his dad's footsteps. Due to the rivalry between his father and Dr. Doofenshmirtz, he and Vanessa try to keep it secret from the two of them, aided by Perry and Carl (though the latter briefly blackmailed Monty in hopes of getting his help in earning Major Monogram's approval). In the special
Phineas and Ferb Save Summer, Monty played a major role as he attempts to help rescue all of the captured agents and defeat the villains of L.O.V.E.M.U.F.F.I.N. in their plan to take over the world by sending it into a new Ice Age.
Dr. Hirano Dr. Hirano (voiced by
Ming-Na Wen) is Stacy and Ginger's mother. She removed Isabella's tonsils in, "I Scream, You Scream." She is often referred to through conversations between Candace and Stacy where Candace gratifies, "Stacy, you're a genius!" and Stacy replies, "Could you call my mom and tell her that?!" She is fluent in both English and
Japanese.
Coltrane Coltrane (voiced by
Corbin Bleu) is Jeremy's friend and bandmate in "The Incidentals". He plays bass and football with Jeremy and his friends. During the summer, he begins a relationship with
Stacy Hirano.
Rodney Aloyse Everheart Elizabeth Otto Wolfgang Hypatia Gunther Galen Gary Cooper von Roddenstein (voiced by
Joe Orrantia), or
Rodney for short, is a bald evil scientist and a member of the villain organization L.O.V.E.M.U.F.F.I.N.. He serves as the main rival to Dr. Doofenshmirtz, believing him to a disappointment because of his constant failures. Throughout most of his appearances, Rodney attempts to best out on Doofenshmirtz to show that he's a much better villain, only to fail so many times (either due to Doofenshmirtz's antics or Perry's intervention). Similar to Doofenshmirtz, Rodney usually makes his own inventions and ends them with the suffix "-inizor". He also has his own robot apprentice named Chloe, whom Norm fell in love with. He also has a son named Orville, who usually helps him create his -inizors. In the episode "Robot Rodeo", Rodney and the other L.O.V.E.M.U.F.F.I.N. members make fun of Doofenshmirtz because of his lack of time management, resulting in Doof completely scrapping his original plans and instead creating the "Eradicate Rodney's Inator-Inator", which has a built-in punching glove that is meant to destroy Rodney's inizor. The inator stays true to its word, and destroys Rodney's inizor, successfully getting back at Rodney and bringing him to tears, but not before shouting "What?! No fair!!", and then walking offstage where he isn't seen for the rest of the episode. Rodney would later go on to appear as the antagonist in the 2014 episode special, "
Phineas and Ferb Save Summer", where he learns that Doofenshmirtz has actually succeeded in moving the Earth away from the Sun to an early autumn with his latest -inator. Taking the opportunity to exploit this, Rodney leads L.O.V.E.M.U.F.F.I.N. into revealing themselves to the world and capturing all of O.W.C.A.'s agents. He even creates an -inizor (which is just ten times the size and strength of Doof's -inator) that will send the Earth into a new Ice Age if the world refuse to meet all of L.O.V.E.M.U.F.F.I.N.'s demands. However, in the end, Doofenshmirtz (who is completely disgusted by Rodney's true goal for worldwide domination) manages to defeat Rodney, who then gets arrested by Monty Monogram and taken into O.W.C.A. custody. ==Other characters==
