    Isabella Garcia-Shapiro
'Cause that's all I really want;
Just time alone with my triangular savant
"Hi Phineas. What-cha doooin'?"
Voiced by: Alyson Stoner

A girl who lives across the way from Phineas and Ferb and is a good friend of theirs. Isabella is a multi-talented member of the Fireside Girls with quite a number of accomplishment patches to her name. She has a not-so-secret crush on Phineas, and likes to pop in once an episode to ask Phineas "What'cha doin'?" and offer to help.

  • The Ace: She has an exceptionally versatile set of skills and is extremely bright and athletic. She uses these abilities to earn Fireside Girl patches - a girl scout group which presents challenges varying from extremely difficult to outright ridiculous. "Act Your Age" reveals that she becomes a resident assistant by the time she starts her first year of college and has joined numerous diverse student organizations.
  • Action Girl: Not shown that often, but comes out in spades when it does. She has defeated Mitch, trashed countless Norm Bots during the Final Battle in The Movie, and saved all of Danville from being trapped in the form of pharmacist zombies.
  • All Jews Are Ashkenazi: Despite every indication that her family is Sephardi, her mom and grandma still talk in Yiddish.
  • Arc Symbol: Like how Phineas is represented by triangles and Ferb by rectangles, Isabella is represented by semicircles, sharing this shape with Candace. This is seen in the background of the credits version of "Tip of the Day", and how Isabella's head is shaped like a semicircle that has the flat side on top.
  • Badass Adorable: See Action Girl above. "Night of the Living Pharmacists" confirms that she knows judo, hapkido, and jiu-jitsu, though she can't use them against the titular pharmacists without becoming one of them. In "Meapless in Seattle", her adorableness is weaponized.
  • Beauty Is Never Tarnished: An odd variation: when she and the Fireside Girls are on their own, she gets ruffled and scuffed, but the instant she's with Phineas she's as neat as ever without a hair out of place.
  • Beneath the Mask: She's not as innocent as she looks.
  • Berserk Button:
    • A mild case, but she tends to get annoyed whenever someone else says her catchphrase. Unless that someone else is Phineas.
    • Also, Phineas being oblivious to her feelings.
  • Beware the Nice Ones: Both one of the friendliest characters and one of the most likely to let you have it when she's angered. In Phineas and Ferb The Movie: Candace Against the Universe, when she and the gang are taken to prison, she gives Doof an Implied Death Threat by showing him a patch that he should "pray [he] never find out what it's for".
  • The Big Damn Kiss:
    • With Phineas in the movie. Then their memories are wiped.
    • And the end of "Act Your Age". This is the first time where he initiates the kiss, rather than the other way around.
  • Billing Displacement: Seasons 3 and 4 credit, as well as the second movie, credit Isabella's voice actress after Baljeet's and Buford's, despite her usually having more lines and screen time than either of them.
  • Birthday Episode: "Happy Birthday, Isabella".
  • Bitch in Sheep's Clothing: Played with, she is not a bitch in any way, but she often puts on a ridiculously ideal nice and sweet persona when around Phineas, when in reality she's a normal person with flaws and all. She does this less and less as the series progresses, growing more comfortable with being herself in front of Phineas in hopes that he'll like her for her.
  • Cannot Spit It Out: Her crush on Phineas has been a running gag from the start. Everyone Can See It, but she can't tell him how she feels. She eventually musters up the courage to tell him in "Night of the Living Pharmacists... but being zombified removes that incident from both of their memories. Phineas only finds out for real when his other friends tell him much later on in "Act Your Age".
  • Catchphrase: "Whatcha doin'?"
  • Character Development: Isabella would often put on a ridiculously nice attitude when around Phineas. Over time, she starts to be more of herself around him — a Nice Girl with flaws.
  • The Chick: The most prominent and sometimes the only female in the main group of kids, and is often the one to pep talk Phineas out of his Heroic BSODs.
  • Childhood Friend Romance: With Phineas. It took him years, but he finally reciprocated her feelings.
  • Child Prodigy: As Fireside Troop leader.
  • Color Motifs: Except in her Fireside uniform, Isabella is always seen in clothing that has purple in it.
  • Coy, Girlish Flirt Pose: Likes to greet Phineas this way.
  • Cute Bruiser: Isabella may be adorable, but she is tough.
  • Cuteness Proximity: She can inflict this on others when she makes the effort.
  • Disappeared Dad: Her father is never seen, except in a few literally blink-and-you'll-miss-it cameos.
  • Distant Duet: With Phineas in "Act Your Age".
  • Establishing Character Moment: She gets hearts in her eyes in the first episode when she sees Phineas.
  • Expressive Accessory: In "Brain Drain" her hair bow went droopy when she was sick.
  • Foot Popping: When kissing Phineas in the movie.
  • Funny Afro: The episode "Robot Rodeo" ends with Isabella's hair frizzy because of the humidity that resembles the "afro puffs" style. She makes also a musical number in funk-style about this.
  • Girl Next Door: Literally to Phineas, she is the across-the-street neighbor.
  • Girly Bruiser: She wears a pink jumper, has a fondness for unicorns, and she's beaten Buford at sports. Considering Fireside Girls can earn a patch for wrestling an alligator, she's probably done that too. She's saved her love interest Phineas from trouble about as much as he's saved her.
  • Girly Girl with a Tomboy Streak: She's girly, romantic, loves unicorns and wears a pink dress. She's also expressed a fondness for gross things and her Fireside Girls' manual includes a lesson on car maintenance.
  • Great Big Book of Everything: The Fireside Girls Manual.
  • Heart Symbol: When she sees Phineas in the first episode.
  • Heroes Want Redheads: Has a massive crush on the redheaded Phineas.
  • Heroic Sacrifice: When she sacrifices her memories of Perry as a secret agent so that Perry can remain Phineas and Ferb's pet in The Movie.
  • Hey, That's My Line!: Whenever someone else says her catchphrase to Phineas, she won't be too happy about it.
  • Hiccup Hijinks: In "One Good Scare Ought To Do It!". She does end up enjoying her hiccups because they get Phineas' attention.
  • Imagine Spot: Shown in "Isabella and the Temple of Sap" and "Bee Day". They tend to involve Phineas suddenly confessing his love to her. Apparently, this happens enough that she has a name for it and the Fireside Girls know about it.
  • Improbable Weapon User: In "Brain Drain", Isabella uses her sash as a weapon in a fighting game featuring themselves to defeat Buford. She has also used a camera to vanish a boss in a video game, a unicorn-shaped kiddie ride to take out an entire group of Norm Bots, and her cuteness to defeat Mitch.
  • Informed Attractiveness: "Meapless in Seattle" suggests that she is the cutest thing in the universe, at least among the characters that we've seen.
  • Instant Costume Change: Pulls this in “Night of The Living Pharmacists” when she yanks her belt upward to change into her Fireside uniform.
  • I Want My Beloved to Be Happy: In "Summer Belongs To You", during Phineas' breakdown, she sacrificed her chance to have a moment alone with him so she can get him motivated again.
  • Laser-Guided Amnesia: As a Heroic Sacrifice at the end of The Movie.
  • The Leader: Of the Fireside Girls Troop 46231.
  • Leitmotif: Plays in most instances where she enters the Flynn-Fletchers' backyard or says "Watcha doin'", or during other miscellaneous moments such as saving Phineas from Mitch in "Meapless in Seattle".
  • Let's Get Dangerous!: Already competent as is. When Phineas is in danger, the kids gloves come off.
  • Literally Loving Thy Neighbor: Has a huge crush on her neighbor Phineas.
  • Magic Skirt: An example in "Isabella and the Temple of Sap" where Isabella's skirt only flutters so lightly in the wind.
  • Mixed Ancestry: Mexican and Jewish.
  • Never Bareheaded: Rarely do we ever see her bareheaded, her hairbow being her usual head accessory.
  • Nice Girl: Isabella is one of the friendliest people in the series.
  • No Brows: Subverted. The "learn to draw" book based on the show states she doesn't have brows and is sensitive about it. Despite this, she is seen with them often, especially in the fourth season.
  • Oblivious to Love: Ironically became this to Phineas. He developed feelings for her in high school (by which point she had given up on him ever figuring out her feelings for him) and she was unaware of this development until he flat out told her in "Act Your Age".
  • Off-Model: The animators seem to have difficulty remembering if she should be wearing her Fireside Girl uniform in a scene or whether she's supposed to be taller than Phineas or the same height as him.
  • One of the Boys: She regularly hangs out with the boys even when not accompanied by the other Fireside Girls and has no problem with participating in any of their activities. In part, this is due to her desire to spend time with Phineas, but there is no question that she is good friends with the rest of the group as well.
  • OOC Is Serious Business: In "Night of the Living Pharmacists", she brushes Phineas aside despite him displaying great concern for her because she had discovered urgent information about the zombie pharmacists that could help the gang save Danville.
  • Pink Means Feminine: Her dress and hair bow.
  • Relationship Upgrade: With Phineas, after high school.
  • Scout-Out: Member of the Fireside Girls. She and her troop have earned many a badge in helping the boys; they have mentioned that they've collected more than fifty of the 'Help Thy Neighbor' patch because of it.
  • Sibling Triangle: "Quantum Boogaloo" reveals that she's going to marry one of the Flynn-Fletcher brothers. It will probably be Phineas, but Ferb seems to hint that he's keeping his options open. "Act Your Age" shows her eventually getting together with Phineas.
  • Single-Target Sexuality: Isabella never had a crush on anyone but Phineas. Except the Beak. Who turned out to be Phineas (and Ferb).
  • Single Woman Seeks Good Man: Isabella has a massive crush on Phineas.
  • The Smurfette Principle: The main girl of the kid cast, and usually the only girl when Candace and the Fireside Girls aren't involved.
  • Strong Girl, Smart Guy: Strong Girl to Phineas's Smart Guy. Phineas is good with tools, Isabella is tough and physically capable.
  • Super OCD: The concept of not earning all the Fireside Girl patches is a horrifying prospect for her.
  • Throw the Dog a Bone: While Phineas remains oblivious to her feelings throughout their childhood, she does succeed in spending time with him alone in a couple of Season 4 episodes ("Happy Birthday, Isabella" and "It's No Picnic").
  • Tsundere: Some episodes seem to indicate that she's a Type B.
  • Tuckerization: Named after Dan Povenmire's daughter.
  • Twofer Token Minority: Hispanic and Jewish. Her family is part of the "Mexician-Jewish Cultural Festival".
  • Unrequited Love Switcheroo: "Act Your Age" reveals that Isabella gave up on Phineas when they started high school, thinking that he'd never figure it out. He started developing feelings for her around the same time, though he never did figure it out — he had to be flat out told by his friends after he said to them that he was fully convinced he was in the friend-zone. In the meanwhile, Isabella remained completely unaware throughout their high school years until he finally told her as she was leaving for college.
  • Vocal Dissonance: In "It's a Mud, Mud, Mud World", she is shown to be capable of speaking in a surprisingly deep voice.
  • Vocal Evolution: Her voice in later episodes tends to be noticeably higher pitched than in her debut.
  • Will They or Won't They?: With Phineas, of course. They Do.
  • Yank the Dog's Chain: Almost anytime when it looks like Isabella is about to have a romantic moment with just Phineas, something happens at the last second to ruin that moment.

    Baljeet Tjinder
I am stone cold honor roll, I won't be told how to vent!
I won't cry or sigh, I'm here to testify,
Up with the establishment!
"I'm running out of underpants!"
Voiced by: Maulik Pancholy

A shrimpy Bollywood Nerd who's more than a little obsessed with order and studying. He's a friend of Phineas and Ferb who occasionally joins in on their daily activity, or even seeks out their advice. Occasionally, they also seek out his, usually when it comes to things like checking their math.

  • Absurd Phobia: He considers a failed math test to be the scariest thing known to man. He also fears contractions.
  • Adorably Precocious Child: He's quite mature and serious about his schoolwork.
  • Ambiguous Disorder: Extremely dependent on routines and clear direction, socially introverted, observant but somewhat oblivious and emotionally stunted, able to focus for long periods on repetitive behaviors, and almost child-prodigy level intelligent.
  • All There in the Script: His surname, which different sources had given as either Patel, Rai, or Raj. It was finally confirmed to be Tjinder on Swampy Marsh's Twitter in 2012, and then solidified in "It's No Picnic"
  • Arc Symbol: Circles, as seen in the credits of "Tip of the Day"
  • Awesomeness by Analysis: Once saved Buford from plummeting to his doom by doing a rapid-fire calculation of his fall trajectory.
  • Badass Bookworm: Usually averted; he's typically the most submissive and least action-oriented of Phineas and Ferb's gang. Check out what he's capable of when not being overshadowed by Phineas and Ferb's brilliance in "Bully Bromance Breakup" though...
  • Berserk Button: Do not make Baljeet do schoolwork and not give him a grade afterwards.
  • The B Grade: A variant. Baljeet didn't take getting an "A-" so well.
  • Big Guy, Little Guy: The little to Buford's big.
  • Big Ol' Eyebrows: Thick, square-shaped eyebrows.
  • Bollywood Nerd: Indian and nerdy, with him even having a song called Baliwood which is done in the Bollywood style with lyrics about why he needs to be smart.
  • Bring My Brown Pants: A Running Gag for him is soiling his underwear whenever he gets scared.
  • Bully and Wimp Pairing: He's a wimpy nerd who's always paired with local-bully Buford, the two also provide the page image for this trope.
  • Butt-Monkey: Not nearly as bad as Candace though.
  • Camp Straight: While there are episodes and moments where he is clearly interested in girls (Wendy and Isabella for example), other moments paint him as Ambiguously Gay, like his unicorn game piece in "Skiddly Whiffers" and dressing up as a flower in "That's the Spirit". In any case, he becomes and Official Couple with Ginger after the Time Skip.
  • Characterization Marches On: Early, he was designed to just be simply a nerd who got bullied by Buford. But as the series progressed, he gained more of a snarky personality, talked back to Buford numerous times and seemed to be more equal with him.
  • Chick Magnet: His childhood friend Mishti, Wendy Stinglehopper, and Ginger Hirano (future girlfriend) all have crushes on him.
  • Child Prodigy: While less mechanically skilled, he is just as intelligent as the title characters. In fact, they sometimes get him to check their math. He becomes a full Professor by the time the others are graduating high school.
  • Crouching Moron, Hidden Badass: When he gets out from under Buford's thumb in "Bully Bromance Breakup", he climbs a mountain completely on his own, by which I mean he even eschews any form of equipment.
    • He takes out dozens of Doof-2's Normbots using the Beak suit... by sissy slapping them.
    • Solidified in "Mission Marvel" when he temporarily gains the same powers as the Hulk.
  • Deadpan Snarker: Especially during the moments when he is aware of his status as a Butt-Monkey.
    • His alternate dimension counterpart shows shades of this, particularly in the spin-off games.
  • The Ditherer: In "Primal Perry", but he gets over it by the episode's end.
  • The Dog Bites Back: In Primal Perry, thanks to the ability to literally make choices without repercussions.
  • Establishing Character Moment: His first appearance (the image above). He's shown studying during summer vacation, and then subsequently being pushed out of chair by Buford.
  • Even Nerds Have Standards: Even he considers Irving to be a nerd.
  • Friendly Enemy: With Buford. Think the normal "bully-and-nerd" dynamic turned into a borderline romantic relationship.
  • Friend or Idol Decision: When he gets out from under Buford's thumb, he gains some pretty extreme competence, to the point that he climbs a mountain and performs some impressive stunts with nothing but the clothes on his back. However, he realized that the achievement felt hollow without Buford, and patched things up with him at the end of the episode.
  • Funny Foreigner: He's from India and is very comical.
  • Give Geeks a Chance: For a nerd, he's had quite some success with the ladies, even outside of "Ferb TV".
  • Hairstyle Inertia: Keeps his same hairstyle into his adulthood.
  • Hulking Out: In "Mission Marvel", he gets Hulkified after Candace plugs in the gamma-ray concentration beam at the wrong time and it hits him.
  • Kidanova: He attempted to hit on Isabella once.
  • Laser-Guided Amnesia: As a Heroic Sacrifice at the end of The Movie.
  • Lawful Stupid: He has a punk song dedicated to this. And it's awesome!
  • Nerds Love Tough Schoolwork: He loves doing math problems and studies during summer vacation. In fact, he can't wait to return to school in the fall, much to the confusion of the other kids.
  • Non-Action Guy: He can design a blueprint, but is inept at even basic construction skills and is generally less physically inclined than his friends. That being said, he's far from helpless, being able to climb a mountain without prior preparation of any equipment and having helped defend Danville from the forces of Doofenshmirtz-2 and Red Skull.
  • Obliviously Evil: "Cranius Maximus" has him attempt to move the Earth's atmosphere to the Moon so that telescopes would have a clearer view of the cosmos- ignoring the fact that no-one would survive to appreciate that.
  • Oblivious to Love: Although it probably helps that Ginger doesn't get to show it as often. He does eventually get together with her by the time of "Act Your Age".
  • Official Couple: With Ginger at some point in the Time Skip, as revealed in "Act Your Age". Ginger herself expressed interest in him before.
  • Only Sane Man: When someone lampshades the logical or scientific inconsistencies that crop up in the show, it's likely to be him. Despite that, he goes along with all the wacky hijinks regardless.
  • Overshadowed by Awesome: When you're The Smart Guy in the group led by two geniuses who are already bright enough as is, there really isn't much for you to do. It is something of a trend that Phineas and Ferb go to Baljeet mostly for help with trivial matters such as to find out what the tip of a shoelace is called. His intelligence occasionally proves useful in the planning stages, such as in "Undercover Carl". Unfortunately, planning stages are often skipped, shortened, or end before Baljeet shows up, making him seem less useful by comparison.
  • Teen Genius: "Act Your Age" shows that by the time the others are getting ready for college, he has already become a professor.
  • Temporarily a Villain: In "Cranius Maximus" and "Primal Perry".
  • Those Two Guys: With Buford as part of their Bully and Wimp Pairing.
  • Tiny Schoolboy: Shortest boy in his circle of friends, along with Phineas.
  • Token Minority: He and his family are the only people of Indian descent in town.
  • Took a Level in Badass:
    • Not exactly badass, but he definitely becomes more confident and more willing to push back against Buford's bullying as the series goes on.
    • In "Mission Marvel", he temporarily gains Hulk powers.
  • Vitriolic Best Buds: With Buford. They even have a song about this.

    Buford Van Stomm
Who will I give noogies to
And tease for being so smart?
"'Wall of meat,' huh? I can do that."
Voiced by: Bobby Gaylor (English), Noriaki Sugiyama (Japanese)

While introduced as the dim-witted, thuggish local bully, Buford has some surprising Hidden Depths, and he eventually becomes a member of Phineas and Ferb's circle of friends. He still exercises a slightly twisted sense of humor, and likes to hang out with Baljeet largely (but not entirely) so he has an easy target for bullying handy.

  • All Drummers Are Animals: Whenever the gang forms a band for a musical number, he plays the drums.
  • Amazon Chaser: He expresses attraction to girls who act "tough" in some way (but, interestingly, never towards Isabella, despite her having such tendencies up to and including beating him at sports).
  • Animal Motifs: He dresses up in a bear suit from time to time. He is also associated with fish, considering his pet is a goldfish and he used a fish as a weapon in "Mission Marvel".
  • Animal-Themed Superbeing: He calls himself Bear Boy in "Mission Marvel".
  • Arc Symbol: He shares Ferb's rectangles as seen in the credits of "Tip of the Day".
  • Badass Normal: In "Mission Marvel", Phineas and Ferb don the Beak suit to fight the villains while Baljeet gains the powers of Hulk from an earlier mishap. Even Perry gets an upgrade by using a superhero suit that allows him to fly. Buford? He jumps into the battle with nothing but a dead fish. Even before that, he was shown to take down a giant squid with just one hit.
  • Barbaric Bully: As mentioned above, he has Hidden Depths, but otherwise fits the template to a T.
  • Berserk Button: Don't mess with his goldfish.
    • Call Buford a wimp/sensitive, and you will receive a painful wet willy.
  • Big Eater: Buford is often seen eating or craving food.
  • The Big Guy: Though he's not dumb as he seems, he still prefers to solve most problems by physical force.
  • Big Guy, Little Guy: The big to Baljeet's little.
  • Book Dumb: He doesn't like math problems.
  • Brooklyn Rage: Has a Brooklyn accent, and is a jerk.
  • Bruiser with a Soft Center: Not that you'll get him to admit it, but he does care about his friends and has expressed interest in stereotypically feminine activities like quilting.
  • The Bully: Regularly mistreats Baljeet on-screen.
  • Bully Turned Buddy: Started as a bully to the brothers and their friends, especially for Baljeet, but mutual help and respect came along, such as rescuing Buford's goldfish, and now Buford is joining the brothers' summer antics, being a foil for Baljeet.
  • Bully and Wimp Pairing: He's a bully who's paired with Baljeet, a wimpy nerd.
  • Card-Carrying Villain: More like "Card Carrying Bully". Loudly and frequently proclaims himself to be a bully, and constantly abuses Baljeet in case anyone around didn't get the message.
  • Catchphrase:
    • "I want the ___."
    • "Buford loves ___."
    • He also has a tendency to say "Witchcraft!" when he sees something he doesn't quite get.
    • "I am so in love with her right now."
  • Characterization Marches On: In his early episodes, he was just a bad bully. However, after the "goldfish" episode, he showed more of his kinder side and is now pretty much a kid who is sometimes violent but overall nice.
  • Child Prodigy: Buford shows flashes of this, from quoting Voltaire in "Summer Belongs to You" to knowing King Wenceslas' background on the Christmas album.
    • He also speaks perfect French, much to Baljeet's surprise. He offhandedly says it was easy to learn due to it's similarity to Latin.
    • He also is able to play quite a few musical instruments, including the drums and the piccolo.
    • It appears he also strives to hide it; in the supercomputer episode, he smacks the mind-scanning screen when it displays an incredibly complex mathematical formula.
  • The Chew Toy: He becomes this from time to time in recent episodes.
  • Cowardly Lion: Whenever he's faced with something he's actually afraid of, such as giant squid or the pharmacist zombies.
  • Crazy-Prepared: If you happen to need some obscure musical instrument, he'll have it with him. He lampshades this in "My Fair Goalie".
    • This:
    Buford: Here's the velvet rope! I never leave home without my velvet rope.
    • He also, for some reason, has life-sized moulds of all his friends, which comes in handy when Candace gets accidentally turned into liquid form by one of Phineas and Ferb's inventions.
    • In "Bully Bust", he prepares for almost every possible contingency when preventing Phineas and Ferb's invention from disappearing, except for random green rays from the sky.
  • Creator Cameo: Voiced by Bobby Gaylor, one of the show's writers.
  • Cutting the Knot: Has a talent for this, such as in "Atlantis" where, when faced with a door to the underwater city covered in hieroglyphics detailing an undoubtedly complicated sequence for opening it, Buford simply punches the door open. And, of course, his infamous jellybean eating in "We Call It Maze"
    • He even explains the Trope Maker story in "Knot My Problem".
  • Deadpan Snarker: Often quick to voice his displeasure this way.
  • Defeat Means Friendship: He and Phineas become friends after Buford beats him at thumb wrestling.
  • Disappeared Dad: His father is never shown.
  • Dumb Muscle: At least, that's what he prefers coming across as. The song about him, "He's a Bully", portrays him this way ("He's big, he's dumb, he's got the IQ of gum, he's got a brain about the size of a sourdough crumb"). This was before he was established to actually be pretty smart.
  • Even Bad Men Love Their Mamas: Which, we assume, is why he named his goldfish after her.
  • Friendly Enemy: With Baljeet. He can be quite jerkish to him, but still cares about him nevertheless.
  • Friend or Idol Decision: In "Bully Bromance Breakup", he begins working with Doofenshmirtz to take over the Tri-State Area. However, upon being told he'd never get to see his friends again, Buford decides to quit and return to being a one-nerd bully.
  • Gasshole: His character on Team Improbable, Belch Man. Especially since he brings up personality power implications.
  • Genius Bruiser: He speaks perfect French. Then goes on to quote Voltaire later in the same episode.
    • As if that wasn't enough, his song in the P & F Holiday Favorites Album CD had him state a brief historical background about the song "Good King Wenceslas" to the tune of said song, surprising Baljeet.
    • He also gets into a short tangent about Personality Powers.
    • In the TV movie, he's revealed to collect existentialist trading cards.
    • We later learn that WHY he learned French—so that he could win over a girl. But, apparently, it was easy for him, because many of the words were similar to their Latin roots.
    • And he was quicker to understand Phineas's jargon in "Cranius Maximus" than Baljeet.
    • Furthermore, a depiction of his brainwaves showed a series of complex math equations (the same as what was revealed for Phineas). He quickly punches out the transmission before anyone notices.
    • In "The Inator Method" he shows that he knows enough about the planets (or mythology) to know that the ancient Greek name for Uranus is Ouranos.
  • Heroic Sacrifice: When he sacrifices his memories of Perry as a secret agent so that Perry can remain Phineas and Ferb's pet in The Movie. In "Night of the Living Pharmacists", he charges at the zombies as a distraction after Baljeet is zombified in order to buy time for his remaining friends.
  • Hidden Depths: Surprisingly knowledgeable and philosophical at times.
    • "Act Your Age" informs us that he becomes a somewhat-snobbish film lover as he grows older.
  • I Just Want to Have Friends: His only friend as a child was a gold fish.
  • Jerkass to One: To Baljeet, constantly pranking and tormenting him.
  • Jerk with a Heart of Gold: In other cases, like the Christmas special, etc. many times. Baljeet only snaps when Buford decides to use a plastic bag over a paper bag at a store.
  • Jerk with a Heart of Jerk: In the Meatloaf Festival episode.
  • Laser-Guided Amnesia: As a Heroic Sacrifice at the end of The Movie.
  • Leeroy Jenkins: This is his usual mode of operation when action is called for. He even parodies the Trope Namer in "The Klimpaloon Ultimatum".
  • My God, What Have I Done?: When he gains a taste of what he usually does to Baljeet, he reacts with horror at what he's been doing, and gives a heartful apology.
  • Nice Guy: More so than his appearance would make you think. Downplayed, as he is a Jerkass to One.
  • Obfuscating Stupidity: Tends to backtrack when he realizes that he has deviated from his "dumb bully" persona.
  • Omniglot: Buford knows Latin and French and doesn't think much of it. He comments that he learned French easily because it shares root words with Latin, a common thought process for omnigots.
  • Pet the Dog: He likes animals. The whole reason he became the local bully in the first place was to protect his goldfish. He's also befriended a flamingo-like alien and taught domesticated squirrels to dance.
  • Precocious Crush: On Candace, apparently. As evidenced by his sneaking his number into her cellphone, and being very upset when she won't abide by the Bully Code and serve him for his having saved her life.
  • Punch-Clock Villain: A bully variant. In his second appearance. These days it's rare for him to be a real bully period, except towards Baljeet. Word of God confirms that his bullying tendencies are more to keep up his self-made image of being a bully rather than out of malice.
    • Teenage Buford has abandoned it entirely in favor of embracing his Francophile artiste side, and is at worst somewhat pretentious.
  • Pungeon Master: In "Remains of the Platypus", his main job was to unload the cheese puns.
  • Real Men Wear Pink: He's expressed the desire to float around like a woodland pixie. He didn't mean to say it out loud though. In one episode, he really gets into quilting. (In contrast, everyone else in the group found it boring.)
  • Sand In My Eyes: A variant. He claims that he is "sweating through his eyes" when he cries and on another occasion transferred his own tear to Baljeet for the sake of denial. However, question him on whether he is sweating through his eyes, and he will admit that he is crying.

    Irving Du Bois
This is what you'll become if you love your idols a little too much.
"Phineas and Ferb rock!! Wooo!!!"
Voiced by: Jack McBrayer

A nerdy local kid who was introduced in "Hide and Seek" as an obsessive fan of Phineas and Ferb and their ambitious antics. He tags along with their daily projects on occasion in later episodes. When he's not geeking out over Phineas and Ferb, Irving can be seen butting heads with his equally geeky older brother Albert.

  • Absurd Phobia: He fears, of all things, the color lavender.
  • All There in the Script: His last name. Confirmed by Swampy Marsh on Twitter after not being mentioned in the show... yet.
  • Ambiguously Bi: He stalks Phineas and Ferb and hits on Candace and Stacy.
  • Annoying Younger Sibling: To his brother Albert.
  • Ascended Fanboy: While one could say he was this from his introductory episode, a better case would be made for his going from a largely ignored Tagalong Kid to Phineas gladly accepting his help on a project in "Doof Side of the Moon", and his friends having no problem taking his advice planning Phineas's birthday in "Phineas' Birthday Clip-O-Rama!"
  • Casanova Wannabe: He's tried his luck with Candace and most of the Fireside Girls, but interestingly, flirting with Isabella is the least likely thing he'd do.
  • Characterization Marches On: While he remains a complete Loony Fan to Phineas and Ferb, his episodes show him steadily becoming less irritating about it, and he eventually goes from a Tagalong Kid to a welcomed member of Phineas and Ferb's inner circle.
    • Adding Albert to the show also gives him something to do other than obsess over Phineas and Ferb, making him a bit more rounded.
  • Cloud Cuckoolander: Not quite as extreme a case as some, but Irving is kind of...odd.
  • Crouching Moron, Hidden Badass: It's implied that he defeats numerous Normbots on his own during the final battle in the movie, in the Beak suit's detached lower half.
  • Drop-In Character: He makes his first appearance showing up at Phineas and Ferb's place uninvited and implies that he regularly does so.
  • Hero-Worshipper: Of Phineas and Ferb.
  • Hidden Depths: He only knows one song, but can perform it well enough to become a global sensation.
  • The Intern: He works as one for O.W.C.A. ten years in the future.
  • Lower-Deck Episode: "Not Phineas and Ferb".
  • Meta Guy: He demonstrates extreme awareness of Running Gags and other aspects of the cartoon, even by the standards of the show.
  • Mission Control: He serves as this on several occasions when Phineas and Ferb have gone into space.
  • My Friends... and Zoidberg
    Phineas: Friends, bullies, Irving...
  • Non-Action Guy: In his debut, he tries to help the others fight a robot and fails epically.
  • Palantir Ploy: Has a complex network of spy cameras set up all over Danville just to capture Phineas and Ferb's exploits, and he proves it by providing footage for the clip show in "Phineas' Birthday Clip-O-Rama!". Already impressive, but some of this footage is from "Phineas and Ferb Get Busted", which means that he somehow managed to set up a spy camera in Candace's dream within Perry's dream.
  • Precocious Crush: In few episodes he hits on Candace and/or Stacy, though this was probably just meant as a single one-off joke in this show's perpetual Ship Tease.
  • Remember the New Guy?: In his first appearance in "Hide and Seek".
    I'm mostly in the background.
  • Shipper on Deck: It's shown that the least likely thing for him to do is hit on Isabella, which is probably because he, like a lot of the show's fans, ships her with Phineas.
  • Sixth Ranger: He's becomes one for Phineas and Ferb's group.
  • Stalker Without a Crush: Has shades of this. "I got in the car when your mom stopped for gas", anyone?
  • Tagalong Kid: He acts like this at first. It's toned down a bit after "Atlantis".
  • The Team Wannabe: He has to actively try and join the group in his early appearances and is treated more like a tagalong. Over time he becomes a more accepted, if irregular, member.
  • Warts and All: Gets a brief moment of this towards Phineas in "Hide and Seek", when he finds out that Phineas relies much more on improvization than he thought. He gets over it quickly, though.

    The Fireside Girls, Troop 46321
We wear our patches upon our sashes
And stand cute, small, and strong!

From left to right: Milly, Gretchen, Ginger, Holly, Katie, Adyson
Gretchen: "Would that be electronically fuel-injected?"
Holly: "It just smells like feet in here!"
Katie: "Excuse me, Phineas. Can I get you to sign some liability waivers?"
Adyson Sweetwater: "Lemme guess, the Let's Help Phineas and Ferb Patch?"
Milly: "Again, forget the idea of little people in there."
Ginger Hirano: "Why don't we ever go see what Baljeet is doing?"

Voiced by: Ariel Winter (Gretchen), Cymphonique Miller (Seasons 1 & 2)/Diamond White (Seasons 3 & 4)/Dana Davis ("Act Your Age") (Holly), Isabella Acres/Soleil McGhee ("Act Your Age") (Katie), Madison Pettis (Adyson), Isabella Murad/Dannah Phirman ("Act Your Age") (Milly), Tiffany Espensen (Seasons 1 & 2)/Michaela Zee (Seasons 3 & 4)/Ming-Na Wen ("Act Your Age") (Ginger)

A group of Isabella's friends from the local Fireside Girls troop. Whenever she helps out with one of Phineas and Ferb's schemes, they often end up getting pulled into the antics too.

  • Action Girls: They are very mechanically skilled and capable of some crazy stunts. Some of their achievement patches require very physically demanding activities.
  • Badass Adorable: The Fireside Girls can earn patches for wrestling alligators and moving mountains...
    • Their theme song even includes the lyrics "We stand cute, small, and strong."
  • Butt-Monkey:
    • Ginger in "Isabella and the Temple of Sap" whenever she expresses attraction to Baljeet.
    • Adyson gets hit hard with it in "The Great Indoors," undergoing several accidents.
  • Crazy-Prepared: Thanks to the Fireside Girls Manual, they are ready for anything from scouting an old abandoned amusement park to repairing a time machine.
  • Early-Bird Cameo: Ginger and Katie appear in a crowd shot in "Rollercoaster."
  • Gadgeteer Geniuses: Most of the time they're just helping the title characters out in the background (which is impressive enough in itself), but they can also build a time machine on their own given only a blueprint (and it was a flawed blueprint too note ).
  • Genre Savvy: Gretchen is this specifically for the Zombie Apocalypse genre. She even hosts bi-monthly seminars on what to do or not do. Didn't keep her from being turned into a repulsive pharmacist, but she did last a while.
  • Great Big Book of Everything: The Fireside Girls Manual has instructions for everything the girls need to do for the plot.
  • Heroic Sacrifice: When they sacrifice their memories of Perry as a secret agent so that Perry can remain Phineas and Ferb's pet in The Movie.
  • Hero of Another Story: Shown especially in their Lower Deck Episodes.
  • Hypercompetent Sidekicks: Not only to the boys, but also to Isabella (who is herself an example of this trope). One of the most notable demonstrations of this is in "It's About Time!"
  • Inexplicably Awesome: It's only spotlighted occasionally, but they harbor a mind-bogglingly immense array of skills between them.
  • The Lancer: Gretchen in "Isabella and the Temple of Sap", Adyson in "Summer Belongs to You", and Ginger in "One Good Turn".
  • La Résistance: Implied in their brief appearance in the Milo Murphy's Law Crossover, where their clothes are especially worn (Isabella in particular looks like a pink Rambo) from resisting the Pistachions, and later they pull a Big Damn Heroes moment by delivering the Murphy's Law super suit.
  • Laser-Guided Amnesia: As a Heroic Sacrifice at the end of The Movie.
  • Let Us Never Speak of This Again: In "Bee Story", Gretchen prevents Isabella from flashing back to the last time they failed to earn a beekeeping patch last year.
  • Limited Wardrobe: Even by this show's standards. "Act Your Age" and a few music montages notwithstanding, they're always wearing their Fireside Girl uniforms and/or colors.
  • Lower-Deck Episode: "Isabella and the Temple of Sap" and "Bee Story".
  • Magic Skirt: An example of this in "De Plane! De Plane!" where the music segment has the Fireside Girls standing on each other in a big, vertical human circle. Their skirts flutter in the wind, but they're otherwise going straight towards their feet.
  • Merit Badges for Everything: Not literally everything (for example, they explicitly don't have a Persistence Patch), but still an enormous number, and frequently for the most ridiculous and unthinkable achievements.
  • Muscles Are Meaningless: They're all super strong and athletic despite being pre-teen girls with little to no muscle mass, considering they move mountains and wrestle alligators.
  • Non-Uniform Uniform: The colors and general design are the same, but there are small differences in each girl's outfit.
    • Gretchen: large collar, bell-shaped sleeves, a red belt around the skirt, and low-top shoes.
    • Adyson: sleeveless uniform with a split in the collar and two splits at the bottom, and high-top shoes.
    • Holly: red collar with a dent and a small split in either sleeve, and red sneakers with a stripe that goes all the way across.
    • Katie: red collar, orange bell sleeves, and red and yellow cleats.
    • Milly: red collar, a red circular pattern on the sleeves and the bottom and black mary janes.
    • Ginger: red turtleneck collar and cuffs, and canvas shoes with a dark red line pattern.
  • Noodle Incident: In "Isabella and the Temple of Sap" they hung out with Baljeet to earn a patch, with Holly saying it wasn't worth it.
    • There's also whatever happened that kept them from getting their beekeeping patches the first time.
    • Plus however Katie wound up covered in bandages after she set out to start a lemonade stand.
  • Only One Name: All except Adyson and Ginger, whose last names are Sweetwater and Hirano, respectively.
  • Pint-Sized Powerhouse: All of them, since it seems moving mountains, wrestling alligators and arm wrestling big, burly men are all par for the course when it comes to being a Fireside Girl.
  • Puppy-Dog Eyes: Their method of getting people to buy their cupcakes.
  • The Reliable Ones: Always ready to lend a hand and can be counted on to complete any task they are assigned.
  • Scout-Out: Evidently based on the Girl Scouts.
  • Shippers on Deck: They sometimes tease Isabella about her crush on Phineas, but are ultimately supportive of her. They are not nearly as understanding towards Ginger's attraction to Baljeet, however. At least, not until they've been an Official Couple for a while in "Act Your Age".
  • Totem Pole Trench: How they navigate the zombified city of Danville in "Night of the Living Pharmacists".
  • Town Girls: Their choices in wardrobe in "Act Your Age" give off this impression. Adyson and Ginger, who both wear bright coloured dresses, headbands and slip-on shoes (and lipstick, in Adyson's case) are the Femme. Katie, who wears a shirt and jeans but they're pink, and Gretchen, who wears a shirt and hat paired with a skirt, are the Neither. Holly, who wears jeans and a jacket, and Millie, who wears a sports shirt, shorts and sneakers, appear to be the Butch. Isabella would appear to be in the Neither category, too, since she trades her skirt for pants as a teenager and wears sneakers, but they're still pink (or at least very light purple) and still has a big bow in her hair.
  • True Companions: They stick together and work extremely well as a team. The entire group is shown to still hang out with one another even ten years later in "Act Your Age", presumably long after they have stopped being actual Fireside Girls.
  • Vocal Dissonance: In "Out to Launch", Gretchen is shown to be capable of speaking in a surprisingly deep voice.
  • What Does She See in Him?: When Ginger enthusiastically expresses interest in Baljeet, the other girls just stare at her like she said something weird.
  • Wrench Wench: They're just as mechanically skilled as the title characters.

Tropes applying to Ginger
  • Ascended Extra: Ginger has had noticeably more focus than the others in season 4, probably because her relationships with Stacy and Baljeet provide additional dynamics beyond simply being backup support for the title characters.
  • Big Sister Worship: Ginger is quite an overachiever, but she won all those trophies so she could impress Stacy.
  • Deadpan Snarker: Ginger in "Bee Story".
  • Foolish Sibling, Responsible Sibling: A downplayed trope, with Stacy being the lazy, underachieving teenager to Ginger's trophy-winning, mountain-moving Fireside Girl.
  • Green-Eyed Monster: "Act Your Age" shows that when Ginger started dating Baljeet she developed a long-standing jealousy of his childhood friend Mishti given Adyson's long-suffering admonition to "let it go" when Ginger mumbled angrily about Mishti.
  • Official Couple: Ginger with Baljeet, as revealed in "Act Your Age".
  • Strong Family Resemblance: Ginger looks like her older sister, Stacy.
  • Strong Girl, Smart Guy: Being a Fireside Girl, Ginger is the strong girl who is capable of many impressive physical feats who also likes Baljeet, who is a typical nerd.
  • The Smart Guy: Ginger gets to do the part in "Bee Story" thanks to a Chekhov's Lecture from Baljeet.

Tropes applying to Gretchen
  • Black Bead Eyes: Gretchen has really dark blue dots for eyes to emphasize her glasses, and she seems to be the only member of the cast to have this. Notably, her stone-age counterpart has normal eyes instead.
  • Child Prodigy: Gretchen.
  • Expy: Gretchen has reddish-brown hair, wears glasses, is around nine-ish, speaks in Sesquipedalian Loquaciousness... just like another Gretchen.
    • Short. Short hair. Small eyes. Glasses. Pheebs, is that you?
  • Sesquipedalian Loquaciousness: Gretchen, going so far as to say sesquipedalian in the show to demonstrate her prowess at it.
  • Shorter Means Smarter: Gretchen is the shortest of the Fireside Girls for most of the series. However, "Act Your Age" shows that she subverts this in their teen years, when she has become the tallest.
  • The Smart Guy: Gretchen is this. Downplayed in that all of the girls are intelligent to some degree as some of their patch earning activities require intelligence. But Gretchen is probably that smartest of them all.

Tropes applying to Adyson
  • Cheated Angle: When she moves her head to the side, her bangs swoop to the other side.
  • Cloudcuckoolander: She says aloud that if she was stung by radioactive bees, she could get superpowers.
  • Girly Girl: Adyson appears to be the most feminine of the Fireside Girls in "Act Your Age" given her blue dress, her Lovable Alpha Bitch personality, her being the only one in the group to wear lipstick, and her being the most enthusiastic about fixing Isabella up with Phineas.
  • Green-Eyed Monster: She is noticeably annoyed when Candace breaks her record of most badges earned in one day in “Fireside Girl Jamboree”. Might be a Visual Pun considering she actually HAS green eyes.
  • Lovable Alpha Bitch: In "Act Your Age", Adyson shows shades of having grown up into one. She offers tips on how to manipulate people, and comes up with the scheme to match-make Phineas and Isabella, but she's only ever presented as an earnest friend offering helpful advice.
  • Number Two: Whenever Isabella is off duty, Adyson usually takes over as leader.
  • Slapstick Knows No Gender: This happens to her in “The Great Indoors”. She gets heatstroke, getting swept away in a current, having a rock fall on her head, and falling ON a rock while climbing a mountain.
  • Sleeves Are for Wimps: She is the only fireside girl with no sleeves on her uniform, and she usually becomes in command when Isabella isn’t around.
  • Tuckerization: Adyson is named after Swampy's granddaughter.

Tropes applying to Katie

Tropes applying to Milly
  • Cannot Keep a Secret: Milly, as implied at the end of "Operation Crumb Cake".
  • Teens Are Short: Millie is a rather exaggerated case in the future, with her being head below the other Fireside Girls and barely looking any bigger or older than in the present day.

Tropes applying to Holly

    Jeremy Johnson
Beautiful, kind and gentle,
And loving and softness and sweetness,
and candy and gum,
"Y'know, Candace, I've had a lot of fun in your backyard, but this is the best time yet."
Voiced by: Mitchel Musso

A nice and easy-going local boy who is the object of Candace's affections. He works at the local fast-food outlet, Mr. Slushy Burger, and plays in a band, "Jeremy and the Incidentals". Later episodes expand on his originally flat characterization, giving him a bit of a snarky side when Candace is freaking out over something or another.

  • Alliterative Name: Jeremy Johnson.
  • Birthday Episode: "Cheers for Fears".
  • Boy Next Door: To Candace. A rare male example.
  • Catchphrase: "That's my girl!" when Candace does something quintessentially Candace-like.
  • Characterization Marches On: In episode one, he was just "the guy" Candace liked, episodes afterwards made him just "the Nice Guy who cheered Candace up". After that, the show slowly chipped away at this one-dimensionalness, revealing things such as the fact that he is the lead singer in a band and is very dedicated to his little sister, Suzy. Now he's also a Nice Guy who likes British things that is on occasion a Deadpan Snarker that messes with Candace's literal mind but still likes her just for who she is. He also, for some reason, carries a drain unclogger around.
  • Childhood Friend Romance: With Candace, though later than most examples.
  • Closet Geek: He’s secretly into He's so embarrassed about it that when Stacy stumbles upon his gear, he begs her not to tell Candace.
  • Hair of Gold, Heart of Gold: Jeremy has blond hair and is a nice guy.
  • Heroic Sacrifice: When he sacrifices his memories of Perry as a secret agent so that Perry can remain Phineas and Ferb's pet in The Movie.
  • He Who Must Not Be Seen:
    • Averted. He was originally going to be an unseen character referenced only in conversations. Mitchel Musso, meanwhile, had been cast as Ferb, but when the creators decided to make him British they wanted to retain Musso's voice, expanding on Jeremy as a result.
    • Played straight for his appearance in Milo Murphy's Law.
  • I Can't Dance: Revealed in "Nerdy Dancin'".
  • Laser-Guided Amnesia: As a Heroic Sacrifice at the end of The Movie.
  • Minnesota Nice: Well, Wisconsin nice. Although he doesn't show any stereotypically Midwestern traits, his family is from Wisconsin and is very nice.
  • Nice Guy: Very nice, which is lucky for Candace. Seriously, this guy's a total sweetheart.
  • The Nicknamer: Though it's only come up in the episode "The Baljeatles".
  • Official Couple: With Candace.
  • Only Sane Man: Jeremy fits this trope pretty well, particularly when he is with Candace. Also, while Jeremy does get in on the show's zaniness, once in a while, one can see the "huh"-type expression on his face. Case in point:
    Phineas: So if we just find Mom, we'll find both Candaces!
    Jeremy: Uh... tell them I said hi...?
  • Pretty Boy: Candace certainly thinks he is.
  • Running Gag: We never, ever get to hear a Jeremy and the Incidentals song all the way through. We either hear the first few lines only for the action to cut away, or we cut to Jeremy singing just as he's wrapping up.
  • Satellite Love Interest: A few episodes tried to expand on his characterization, but for the most part, he didn't seem to have any personality except "ambiguously (or not) likes Candace". Later episodes fix this a bit, giving him some more personality. He's calm, mature, responsible, and hardworking. He's also incredibly dedicated to his sister Suzy, has his own friends, and responds to Candace's antics with some accepting amusement and snarking.
  • Savvy Guy, Energetic Girl: The laid-back Savvy Guy to Candace's neurotic Energetic Girl.
  • Single-Target Sexuality: He does not seem interested in other girls, but only Candace.
  • Unfazed Everyman: He pretty much just rolls with whatever weird stuff goes on around him, including his girlfriend's often erratic behavior.
  • Unrequited Love Switcheroo: The episode Knot My Problem implies that he had a crush on Candace when they were in grade school together, completely unbeknownst to her.

    Stacy Hirano
You were always there for me, on you I could depend.
"Oh, lighten up, Candy."
Voiced by: Kelly Hu

Candace's best friend since childhood. Stacy is remarkably more laid-back and unfocused than Candace, and usually tries (with little or no success) to convince her to lighten up over busting Phineas and Ferb, trying to impress Jeremy, or whatever else Candace is worrying about. She also knows about Perry's secret identity.

  • Action Girl: When the situation calls for it. She helps fight off the Norm Bot invasion in the movie. Parodied in "Phineas and Ferb Busters", when Candace makes her and Jenny go through some physically taxing exercises so they can assist her in busting Phineas and Ferb.
  • All Women Love Shoes: Stacy seems to love shoes enough to make a gelatin mold of some pumps.
  • Ascended Extra: In the early episodes, she appeared only infrequently, if at all (she was originally just an unheard voice on the other end of Candace's cell phone conversations). As the series progressed, she appeared much more often, and has played a role in the plot of some episodes ("Put that Putter Away", "Elementary my Dear Stacy", "Phineas & Ferb-busters", "The Lemonade Stand"). In fact, it was almost rare to see a episode after Season 1 (and before "Night of the Living Pharmacists") where she doesn't appear, even if it's only for a scene or two.
  • Asian Airhead: Type II and a mild case at best. She has occasional Cloudcuckoolander tendencies and is sometimes shown to lack basic knowledge about geography, but Candace's own personal manias make Stacy the more level-headed one fairly often.
  • Attention Deficit... Ooh, Shiny!: Stacy has problems focusing on catching the boys, particularly when they're doing something she finds cool, like miniature golf. At least some of it is because she doesn't have a personal stake in busting the boys, she's just helping her friend.
  • Beta Couple: With Coltrane. However, he rarely appears.
  • Book Dumb:
    Candace: Do you know what they have in France?
    Stacy: The pyramids?
    • And later:
    Candace: Oh, and Stacy, pyramids? Really?
    Stacy: Oh, I get it. Those are Belgium, right?
  • Butt-Monkey: In several episodes, such as "Spa Day".
  • Catchphrase: "Would you call my mom and tell her that?" whenever Candace calls her a genius.
  • Characterization Marches On/Character Development: Stacy is starting to look like the sane girl to Candace's busting-obsession neurotic teenager and tends to be skeptical of her more insane claims. Made very clear in The Movie.
  • Childhood Friends: She and Candace have shared an enduring friend relationship. It is unknown when they met or how they became friends. What is known is that their relationship can be traced as far back as the third grade, when they were trying to impress a boy named Billy Clarke, as mentioned in "Spa Day".
  • Cloudcuckoolander: On some occasions, such as in "Ready for the Bettys". Subverted most of the time though, with her being the more grounded one compared to Candace.
  • Cool Big Sis: Ginger views her as one.
  • A Day in the Limelight: "Put That Putter Away" and (unexpectedly) "Happy Birthday, Isabella".
  • Deadpan Snarker: Towards Candace a lot. At one point she even rebukes herself for being "too deadpan."
  • Disappeared Dad: Her father never appears or mentioned.
  • Foolish Sibling, Responsible Sibling: A downplayed trope, with Stacy being the lazy, underachieving teenager to Ginger's trophy-winning, mountain-moving Fireside Girl.
  • Heterosexual Life-Partners: With Candace; they are best friends.
  • Informed Ability: According to her Top Trumps playing card, she's into figure skating, despite never showing this trait in the show.
  • Laser-Guided Amnesia: As a Heroic Sacrifice at the end of The Movie. And then averted in "Happy Birthday, Isabella".
  • Not So Above It All: She will sometimes go along with Candace's Zany Schemes, even right after pointing out their flaws.
  • Obfuscating Stupidity: In "Canderemy", Doofenshmirtz's latest creation has Candace and Jeremy (the latter sleeping) joined at the hip after Candace has promised Stacy not to so much as mention Jeremy for the entire day. Candace spends the entire day hiding Jeremy in more and more wildly improbable places so Stacy doesn't catch on and get angry. Eventually, the situation is resolved and Stacy says the following:
    Stacy: By the way, the best part was when you used him as a table.
  • Official Couple: With Coltrane.
  • Only Sane Woman: Especially when compared to Candace.
  • Out of Focus: Following "Night of the Living Pharmacists" she makes no appearances aside from a reused clip in the finale. Since this episode, Vanessa more or less takes over her role as Candace's most frequent friend and companion.
  • Red Oni, Blue Oni: The blue to Candace's red. Candace is the paranoid, loud mouthed teen obsessed with busting her brothers, while Stacy is the Only Sane Man (or girl) who acts as the Voice of Reason. Fittingly, Candace wears a red tank top while Stacy wears a blue skirt.
  • Rude Hero, Nice Sidekick: She's comparably nicer and more laid back compared to the easily angered Candace.
  • Satellite Love Interest: Coltrane to her.
  • Secret Keeper: At the end of "Happy Birthday, Isabella", Stacy learns that Perry is a secret agent. She promises to keep this secret, and Perry agrees not to wipe her memory.
    • As of "Druselsteinoween" she's now assisting Vanessa in keeping her relationship with Monty secret from Major Monogram.
  • Spell My Name with an "S": Her name is sometimes misspelled "Stacey", but that's actually the masculine variant of the name.
  • Straight Man: Becomes this to Candace over time, as Candace's neurotic tendencies become more and more apparent.
  • Strong Family Resemblance: All of her female relatives in Tokyo look like clones of her. Also, her little sister Ginger.
  • Token Minority: She and her family are Japanese.
  • Tomboy and Girly Girl: Stacy is the girly girl to Candace's tomboy. A conflict which often occurs between the two is how Stacy would rather be doing typical teenage girl stuff like shopping at the mall, while Candace would rather be busting her brothers. In addition, Candace is aggressive, loud mouthed, confrontational, hot headed and not very ladylike, while Stacy is more passive (though she does have her limits as shown when Candace pushes her levels of tolerance for her antics too far), polite, mellow and has a greater interest in shoes than Candace has.
  • Unfazed Everyman: Even Perry and Doofenshmirtz crashing a truck straight into her home and proceeding to fight all over the living room doesn't faze her nearly as much as one might expect.

    Carl Karl
"Sorry about that, sir."
Voiced by: Tyler Mann

Major Monogram's assistant, a nerdy college intern working for O.W.C.A. who occasionally banters back and forth with Monogram while Perry the Platypus is being sent out on a mission.

  • Action Survivor: In "Save Summer", he helps Perry and Monty sneak into the headquarters of LOVEMUFFIN but is noticeably (and understandably) less involved in the action than they are.
  • Alliterative Name: Sort of. Carl Karl.
  • Awesomeness by Analysis: Which makes him quite a competent threat after being turned evil. He was able to infer Perry's whereabouts correctly by identifying an obscure flower he saw in the background while video-calling Perry.
  • Butt-Monkey: In the sense that he is frequently berated and ignored, often unfairly.
  • The Cassandra: On the rare occasions where he acts as the voice of reason to Monogram, he is almost always unacknowledged or entirely ignored. And on one occasion ("Undercover Carl") where Monogram does take heed, he turns out to be wrong.
  • Celeb Crush: Maia Mitchell.
  • Crazy-Prepared: He built robotic duplicates of the Flynn-Fletcher family in case one of them gets their memories erased. Major Monogram is a bit freaked out.
  • Distaff Counterpart: Carla, who is implied a relative of his.
  • Ditzy Genius: Not to the same extent as Doofenshmirtz, but he does blunder often and spends a lot of time goofing off with Monogram. Yet his intelligence makes him one of the most competent villains in the entire series when he is turned evil.
  • Dude, Where's My Respect?: "Where's Perry" explores this heavily, with this being his main motivation after being turned evil. Monogram finally grants him some respect at the end of the episode. Also comes up in "Thanks But No Thanks", in which he points out that Monogram has never thanked him for all the work he does at the agency.
  • Expy: He has been compared appearance wise to King of the Hill character Hank Hill.
  • Gadgeteer Genius: Not shown very often, but he did create functional robot duplicates of the Flynn-Fletcher family (and then some).
  • Hidden Depths: When Carl finally gets a song of his own in "Where's Perry?", Monogram admits that he's a good singer, despite it being his villain song.
  • The Intern: Works as one in the O.W.C.A.
  • Latex Perfection: His standard disguise as a black, female clerk is pretty convincing.
  • Lower-Deck Episode: "Undercover Carl".
  • Mecha-Mooks: Uses these when he is turned evil.
  • Mission Control: Rarely, but he gives Perry his missions when Monogram is unavailable.
  • Mundane Made Awesome: His theme song makes all the mundane jobs he does sound awesome.
  • Non-Action Guy: Despite working at an agency that employs badass secret agents, his job is to complete menial tasks like working the camera and fixing paper jams. He does manage to subvert this a little in "Where's Perry", but still mostly relies on his Mecha-Mooks.
  • Non-Promotion: Is given the title "Paid Intern" in "Where's Perry?", but it's just a title and doesn't actually grant him any pay. He's still happy about it.
  • Not-So-Harmless Villain: Carl is a bit of a wimp, but when he turns evil in Evil For Extra Credit, he is shockingly competent and dangerous.
  • Repetitive Name: The end credits initially misspelled his name with a K, which was then explained away as his last name.
  • Secret Keeper: For Monty and Vanessa's relationship.
  • Spell My Name with an "S": The character's first name is officially spelled Carl on the show, despite the ends credits spelling it with a K. Perhaps due to this, "Ain't No Kiddie Ride"'s credits lists him as Carl Karl.
  • Temporarily a Villain: In "Where's Perry?" when he is hit with the Ultimate Evil-Inator and turns evil.
  • This Is Your Brain on Evil: This is what happens to Carl after getting struck by Doofenschmirtz's Ultimate Evil-Inator. Thankfully, he is cured at the end of the two-part episode, but he is surprisingly competent as a villain, and he nearly wins in the end.
  • Those Two Guys: With Major Monogram.
  • Villain Song: "Evil for Extra Credit", when he's turned evil by one of Doofenshmirtz's -inators in "Where's Perry?".
  • "Well Done, Son!" Guy: Carl would like to have been Monogram's son and he does everything to please him.
  • Would Hurt a Child: When turned evil, he lures Perry out of hiding by putting Phineas, Ferb, and their friends in danger.
  • You Are in Command Now: Temporarily in "Save Summer" when Monogram is fired. He is rather overwhelmed by the new responsibility.
    • Ten years later in the future, he becomes an O.W.C.A. Commander for real, and appears to be handling things well enough.

    Vanessa Doofenshmirtz
I'm a blood-red rose with a string of thorns, I'm me!
I'm a heart-shaped locket on a cold steel chain, I'm me!
"I so should've gone to summer school."
Voiced by: Olivia Olson

Dr. Doofenshmirtz's teenage daughter. When she's not being embarrassed by her father's bungling attempts at being evil, she's being embarrassed by his attempts at doting on her. Despite all that, she does love him.

  • Action Girl: Just watch "Vanessassary Roughness" where it shows what she's capable of when motivated. Her "I Am" Song "I'm Me" from that episode showcases her in action.
  • All Girls Want Bad Boys: Deconstructed. She had a thing for "bad boys", which one of the reason she dated Johnny. However, in “Minor Monogram”, Vanessa broke up with him because she thought Johnny felt that a video game was more important than her. Afterwards, she decided to be a Single Woman Seeks Good Man.
  • Aloof Dark-Haired Girl: Tall? Aloof and composed? Dark haired? She's three for three.
  • Birthday Episode: The B-plot of "Dude, We're Getting the Band Back Together".
  • Bratty Teenage Daughter: Vanessa has her moments.
  • The Cassandra: When she tries to tell her mom that Dr. Doofenshmirtz is evil.
  • Characterization Marches On: After only two episodes of showcasing it, the above-mentioned The Cassandra quality seems to have been dropped from her character, perhaps to serve as a parallel to Candace since those episodes were a reversal of the show's usual formula. Part of it is because in later seasons, she realizes deep down, there is good in him and just needs help.
  • Daddy's Girl: Their father-daughter relationship is somewhat strained, Doof being an incredibly embarrassing Overprotective Dad who's divorced from Vanessa's mom, but she clearly cares a whole lot about him.
    • Doofenshmirtz goes to crazy lengths to make his daughter happy, even if he's wrong about what would make her happy. The one slam dunk he made was finding a Mary MacGuffin doll for years after Vanessa had given up looking for one and she was so happy she sang a song about how he's "Not so bad a dad after all."
  • Daddy's Little Villain: Downplayed.
    • "Finding Mary McGuffin" does have her do something nasty, though.
    • As does "Summer Belongs To You" where she "rents" a scooter and later holds up Major Monogram and Perry to rescue her father.
    • She is Daddy's Little Villain, what with her stealing her father's Catchphrase when she's carried off by her father's Pick'emUp-Inator in "Candace Disconnected".
    • In "What'd I Miss", she acts as his henchman. Granted, all she had to do was hand him a ray gun, and then she could go back to relaxing on the beach (and it probably helped that Doof had to execute his plan on the beach in the first place). But it's still interesting to notice that she didn't seem to mind. Not even one snarky remark!
    • Ultimately averted however. Not only does she never truly become evil, she joins the heroes and ultimately convinces Doofenshmirtz to give up evil as well.
  • Dating Catwoman: With Monty Monogram.
  • A Day in the Limelight: "Vanessassary Roughness".
  • Deadpan Snarker: "I should have gone to summer camp!".
  • The Dragon: To her dad sometimes.
  • Dude Magnet: Several guys in the show attempted to hit on Vanessa. Ferb has an obvious Precocious Crush on her, Johnny was her boyfriend (in “Dude, We're Getting the Band Back Together” and “Brain Drain”) and after she broke up with him she dated Monty, Monogram's son.
  • Evil Counterpart:
    • Vanessa isn't evil but in the song "Busted" and in the episodes "Finding Mary McGuffin" and "Hail Doofania" she does come across as a Darker and Edgier counterpart to Candace, even in their respective relationships with their fathers, sometimes.
    • Played straight in the Second Dimension, where the Doofenshmirtz family is definitely evil.
  • First Girl Wins: She was the first girl Ferb met besides Isabella, and she ends up dating him in the future.
  • Freaky Fashion, Mild Mind: She wears a Goth style and has a bit of a sarcastic streak, but she can be quite friendly to others, as shown in "Summer Belongs To You."
  • Goth: People keep referring to her (or more often her look) as a goth, but she refers to her clique as being punks.
  • Hypocritical Heartwarming: While she hardly respects her father that much, she won't stand for Monty insulting him; she doesn't even take kindly to those who would betray her father for more nefarious purposes, as shown in "Minor Monogram" where she is horrified to witness her father being betrayed by Rodrigo, who plans to destroy the Tri-State Area by splitting it into two.
    Rodrigo: (after betraying Doofenshmirtz) Join me, Vanessa, and together we will take over the world. I'll let you get a tattoo. I think boots should come in pairs, like people.
    Vanessa: (angrily) Join you? I don't work for him! That's my father, you dweeb!
  • Impossible Hourglass Figure: She's one of few high school age character on the show to have a "womanly" kind of body, especially compared to the more angular and sharp-edged Candace (as their Clothing Switch in "Hail Doofania" made incredibly obvious) and Stacy.
  • The Intern: At the end of summer, she gets an internship at the O.W.C.A.
  • Kick the Dog: As mentioned above, in "Finding Mary McGuffin" when, at near the end of the episode, Candance and Vanessa began fighting over the Mary McGuffin doll. It flies into the hands off a little girl and both look at it for a moment, seeing how much she liked it. Candace decided to let it go, Vanessa just took it.
    Doofenshmirtz: So you just took it from a little girl and left her there crying? Wow, that is evil. Honey, I'm so proud of you! It felt good, didn't it? Yeah, we can build on this.
  • Lethal Chef: Apparently, even her adoring father can't stomach her baking.
  • Mad Scientist's Beautiful Daughter: She plays with this trope in different ways. In early episodes she was outright disdainful towards her father and his experiments, generally playing the role of Deadpan Snarker. She warmed up to him in later episodes, though she remains somewhat annoyed by his exploits and his attempts to make her into a Daddy's Little Villain (though some of her actions hint she may head down that path anyway). She's also notably uncloistered (she only spends alternate weekends with her father anyway) and keeps her relationship with his nemesis friendly but strictly platonic. Played Straighter when she develops an interest in Major Monogram's son, Monty Monogram and they keep their relationship secret from their parents.
  • Morality Pet: To her dad Doofenshmirtz; she's even the one who convinces him to reform.
  • Ms. Fanservice: She's the only female non-adult character in the show with serious curves and her outfit hugs them tightly. And speaking of "I'm Me" up above check out the hip action.
  • Odd Friendship: Sometimes with Candace. A lot of their relationship is unknown so far, and although they don't meet up with each other often they have become friends.
  • Off-Model: For her appearance in Milo Murphy's Law, she is drawn somewhat shorter than usual. Most likely because the animators haven't drawn her since the series finale.
  • Official Couple:
    • Revealed in 'Brain Drain' that she's going out with Johnny, then subverted in "Minor Monogram" when she breaks up with him and develops an interest in Monty.
    • Word of God says she'll probably get together with Ferb one day when they're older, though. It seems she's been dating Ferb for a while in "Act Your Age".
  • Out of Focus: Not as much in regular episodes, but she doesn't appear at all in the Christmas special, "Mission Marvel", and "Save Summer" and has a fairly minor role in "Phineas and Ferb Star Wars". She also doesn't make an appearance in the movie, though she and her alternate universe counterpart were originally planned to have each had a brief scene.
  • Perky Goth: ...whenever her dad's not around to embarrass her.
    • Actually addressed in one episode, where Vanessa informed her father that she and her friends were "Punks, not Goths." Although he'd actually been further off than that and thought it had something to do with Visigoths.
  • Perpetual Frowner: To the point where Doofenshmirtz thinks there's something wrong when he sees her smiling in "My Sweet Ride".
  • Pet the Dog: In "A Real Boy", she gives her MP3 to Norm at the end to cheer him up, and humors him in his statement of her being his "sister".
  • Show Some Leg: Her Vampire Queen costume.
  • Single Woman Seeks Good Man: After having enough of dating bad boys, Vanessa decided to date "good guys".
  • Sir Not-Appearing-in-This-Trailer: A movie variant. She and her second dimension counterpart were going to appear in the movie, but were cut.
  • Statuesque Stunner: Vanessa is the same height as Candace, 5'8.
  • Tall, Dark, and Snarky: Tall? Check. Snarker? Check. Dark? Check.
  • Tomboy and Girly Girl: The tomboy to Candace's girly girl, which was emphasised when the two accidentally swapped clothes.
  • The Ugly Guy's Hot Daughter: To her dad Doof.
  • Wacky Parent, Serious Child: She is very mature compared at her Mad Scientist dad, Dr. Doofenshmirz.
  • What Happened to the Mouse?: In "Last Day of Summer", Vanessa reveals to her father that she got an internship at OWCA. However, in "The OWCA Files", Carl is still somehow interning and Vanessa is nowhere to be seen.
  • Why Couldn't You Be Different?: Zig-Zagged in 'A Real Boy', Doofenshmirtz accidentally lets slip to her that he would have preferred having a son but reversed via Exact Eavesdropping, as Doofenshmirtz was deriding his rival, Rodney, for such notions. Finally averted altogether as Vanessa was wearing headphones and couldn't hear a word Doof was saying to begin with.

    Suzy Johnson
Were you traumatized by squirrels?
Or a little girl with curls?
"I am, and always will be Jeremy's favorite girl!"
Voiced by: Kari Wahlgren

Jeremy's little sister. Despite her cutesy demeanor, she's quite manipulative, and fiercely jealous of any girl trying to get Jeremy's attention.

  • Big Brother Attraction: Although it lacks any sexual qualities, she still wants Jeremy all to herself. And it's still very creepy. However, it's later implied that she doesn't really care that much about Jeremy and only likes the perks she gets from being his "favorite girl".
  • Bitch in Sheep's Clothing: She pretends to be a dumb innocent girl, but in reality she is very smart, and cruel to whoever threatens her relationship with Jeremy.
  • Child Prodigy: Far more knowledgeable and articulate than her age would suggest, though she hides this from most people.
  • Clingy Jealous Girl: A sibling version to Jeremy, wanting his attention and threatening anyone who gets in the way.
  • Creepy Child: Though only Candace and Buford recognize her as one. In an interesting twist however, her true nature is only revealed to manifest when someone tries to "steal" Jeremy from her, which gives her relatively little time to express it. She even drops this tone when Candace isn't actively vying for Jeremy's attention.
  • Deliberately Cute Child: She acts sweet and innocent in the eyes of her brother, but when she crosses paths with his girlfriend, Candace, she shows her True Colors when Jeremy isn't looking. Ironically, this means that practically no one besides Candance and Buford are apparently aware of the act, as everyone else either isn't interested in Jeremy or can detect evil like Buford.
  • Demoted to Extra: In season four, Suzy doesn't have any speaking lines, and probably her only significant non-speaking role was in "Just Our Luck", where she attempts to spray Candace during the song, but because of Candace's good luck, she ends up getting sprayed herself.
  • Devil in Plain Sight: Candace and Buford are the only ones aware that she is evil, and she does a good job at hiding it.
  • Enemy Mine: Sort of, Candace once has to babysit her and the two of them wind up teaming up to try and get Phineas and Ferb to bust themselves.
  • Enfant Terrible: Is apparently the most horrible thing in the world to Buford, the local bully, who all the other kids fear.
  • Jerkass to One: While she's certainly not as nice as she acts, she reserves the worst of her vitriol for Candace. Though this only applies when Jeremy's around; since her ire towards Candace is motivated entirely by her feelings for him, she's perfectly capable of getting along with her when Candace isn't trying to pursue her brother.
  • Karma Houdini Warranty: In her earlier appearances she never received any comeuppance for tormenting Candace, but "Comet Kermillian" and several episodes in Season 3 had several of her schemes backfire on her. For example, in "Let's Bounce" she is hit with Doofenshmirtz's Tell-The-Truth-inator, making her confess to deliberately making Candace looking bad all morning. This caused her parents to scold her for it.
  • Manipulative Bitch: She loves to manipulate people, from Candace to Jeremy to (alongside Candace) Phineas and Ferb.
    • "Suddenly Suzy" seems to indicate that she believes all sisters should be this toward their brothers, given how appalled she acts upon finding out that Candace is not.
  • My Brother Is Off Limits: Something she makes very clear to Candace.
  • Obfuscating Stupidity: Part of her acting.
  • Ping-Pong Naïveté: In most of the episodes which feature her, she's frighteningly intelligent, manipulative, and (in a way) mature. Then, in Nerds of a Feather, she gets frightened by an Alien-esque exhibit and seeks a hug from a cuddly costumed character from her favorite cartoon. This could be an attempt to uphold to the the show's proclamation of "no mean characters" by reminding us she's still a child.
  • Practically Different Generations: Appears to be preschool-aged while her older brother Jeremy is 16.
  • Punch-Clock Villain: When Suzy doesn't have the opportunity to embarrass Candace in front of Jeremy, she's acting civil towards her. She even uses the phrase "I'm off the clock".
  • True Colors: Her actual personality is that of a psycho that threatens anyone who tries to take Jeremy from her, but this personality rarely manifests given how specific the situation is, and thus no one suspects it.
  • Yandere: Take that Big Brother Attraction and make it creepy and you have Suzy in a nut shell.

    Monty Monogram
I know that you and I
We come from different places,
There's no telling why or who your heart embraces.
"I hope to follow in my father's footsteps and join you in the battle against evil."
Voiced by: Seth Green

Major Monogram's son who recently graduated from the High School Without A Cool Acronym, and now wants to fight evil like his father.

  • Dating Catwoman: With Vanessa Doofenshmirtz.
  • Fedora of Asskicking: Wears one on his first official mission, during "Save Summer"
  • Follow in My Footsteps: Inverted. His father tries so hard to make it clear Monty doesn't have to do this, that he inadvertently pushes Monty toward being an acrobat instead, despite the fact that Monty is completely on board with fighting evil.
  • I Know Madden Kombat: Beats up Rodrigo with acrobatics.
  • Only Sane Man: Compared with his father and Carl. When Perry gets in trouble on a mission, he's the only one who notices.
  • Remember the New Guy?: Despite being Major Monogram's son and acquainted with Perry, he is not introduced until Season 3. This is explained by him having been in high school until recently.
  • Romantic False Lead: According to "Act Your Age", Vanessa eventually ends up with Ferb in the future.

    Albert Du Bois
He's Irving, but older.
"They call me... the Truth Detector!"
Voiced by: Diedrich Bader

Irving's older brother, with whom he often butts heads.

  • Small Name, Big Ego: He calls himself "The Truth Detector", but is easily fooled in "Not Phineas and Ferb".

    Jenny Brown
She loves world peace, dogs, and pigeons.
"Save the pigeons!"
Voiced by: Alyson Stoner

A hippy-dippy friend of Candace's who shows up on occasion. Word of God has said that she is Django's sister. Like Django, she has suffered from being Out of Focus on the show.

  • Action Girl: Parodied in "Phineas and Ferb Busters", when Candace makes her and Stacy go through some physically taxing exercises so they can assist her in busting Phineas and Ferb. In a straighter example, she helps fight off the Norm Bot invasion in the movie.
  • The Bus Came Back: Both she and Django finally have brief speaking roles again in the season four episode "The Inator Method".
  • Demoted to Extra: After Season 1, Jenny rarely appears on the show and just as a cameo, until The Bus Came Back.
  • Flat Character: Besides her being a Granola Girl, we don't know anything more about her.
  • Granola Girl: With a history of participating in various protests along with an inherent desire for world peace, she can be characterized by her hippie-like nature.
  • Rapunzel Hair: Probably comes with being a hippie.
  • Soapbox Sadie: Has a history of participating in various protests.
  • Tuckerization: Named after Swampy's daughter.
  • The Voiceless: Hasn't spoken since season 2. Likely because of the policy that voice actors must be paid more once a show reaches season 3 and they don't want to pay Alyson Stoner for two roles.

    Django Brown
Kids, Don't Try This at Home! He's a professional and also a cartoon character.
"I made this for my Dad, but it hardly compares to his stuff."
Voiced by: Alec Holden (Season 1), Alex Garrett (Season 4)

A friend of Phineas and Ferb's. His father is an installation artist, and some of his father's love of the arts seems to have rubbed off on him. Other than that, there's not much to say about him, which is probably why he's not seen much in later episodes.

  • The Bus Came Back: Both he and Jenny finally have brief speaking roles again in the season four episode "The Inator Method".
  • Chuck Cunningham Syndrome: Django was featured prominently in four early episodes, and was even a member of Phineas and Ferb's close-knit group of friends. After "Oil on Candace" he disappeared from the main cast, and has been seen only in a handful of non-speaking cameos.
  • Day in the Limelight: "Oil on Candace".
  • Demoted to Extra: Originally appeared in 2 episodes as one of the boys' friends, now generally absent.
  • It Runs in the Family: His artistic talent.
  • Rubber Man: Averted in "Jerk De Soleil", where he claims to able to put his foot behind his head.
  • Tuckerization: Named after Swampy's son.
  • "Well Done, Son!" Guy: Wants to create a giant work of art to impress his father. Unfortunately, when Phineas and Ferb help him make one, it washes away before his father can see it. However, his father does see his regular-sized artwork and is more than appreciative of it.

Voiced by: Corbin Bleu

A member of Jeremy's band and a love interest to Stacy.

  • Flat Character: We know that he's into music, but that's about it.
  • Foil: In "The Baljeatles", his and Stacy's budding attraction serves as a foil to the far more insecure Candace's relationship with Jeremy.
  • Ink-Suit Actor: He has two designs, and one of them resembles his voice actor quite a bit.
  • Nice Guy: He's a pretty decent guy.
  • Nice Hat: Is sometimes seen wearing a red hat.
  • Official Couple: With Stacy.
  • Satellite Character: To two different characters; he rarely appears without either Jeremy or Stacy.

    Mandy, Thaddeus, and Thor
Meeting the neighbors.
Mandy: "In terms of obnoxiousness, I'm sure my brothers have your brothers beat."
Thaddeus: "Well, Thor, I know who we're gonna outdo today!"

Voiced by: Aliki Theofilopoulos (Mandy), Danny Cooksey (Thaddeus)

Niece and nephews of the Ferb-Fletchers' next-door neighbor Mrs. Weaver.

  • Always Someone Better: Learn this the hard way when Phineas and Ferb outclass them in their debut episode. They never challenge the titular duo again.
  • Annoying Younger Sibling: Like Candace, Mandy considers her brothers' projects to be annoying. Unlike Phineas and Ferb, however, Thaddeus and Thor really are Jerkasses.
  • Child Prodigies: Nowhere near Phineas and Ferb's level, but Thaddeus and Thor still have above-average construction skills.
  • Creator Cameo: Mandy is voiced by storyboarder Aliki Theofilopoulos.
  • Evil Counterpart: While Thaddeus and Thor aren't evil per se, they're certainly bigger Jerkasses, a sharp contrast against Phineas and Ferb.
  • Gadgeteer Geniuses: Not as much as Phineas and Ferb, but enough to qualify.
  • Gag Nose: Thaddeus has the same head shape as Phineas.
  • I Think You Broke Him: Mandy says "I think you broke their brains!" when Thaddeus and Thor are stunned stupid by Phineas and Ferb's fort.
  • Jerkass: Thaddeus behaves condescendingly to everyone he speaks to.
  • Overshadowed by Awesome: The reason they lose against Phineas and Ferb is because they're limited by physics and logic.
  • The Quiet One: We never hear Thor speak.
  • The Rivals: Set up as these for the Flynn-Fletcher kids in their debut. However, Phineas and Ferb do not reciprocate, only competing with their counterparts after being requested to do so by Candace. On Candace and Mandy's side of things, Mandy admits that Phineas and Ferb are more skilled than her brothers after seeing what they are capable of, and her subsequent interactions with Candace have been friendly.
    • The one-sidedness of the rivalry is seen as their snobby behavior is met with Politeness Judo by Phineas and Ferb.
  • The Silent Bob: Fittingly for Ferb's Evil Counterpart, Thor has not said a word on screen.
  • Silent Partner: Thor.
  • Small Name, Big Ego: Thaddeus and Thor's inventions don't hold a candle to Phineas and Ferb's, but you wouldn't know that by looking at their ego. The main problem seems to be that they can only achieve possible things, while P&F have no such constraints.
  • Villainous BSoD: Upon seeing Phineas and Ferb's fort. May have killed their drive to invent things.

    Eliza Fletcher
Ferb's cousin.

Voiced by: Jane Horrocks

Ferb's cousin and the step cousin of Phineas and Candace.

  • Hypocritical Humour: Eliza sings a song explaining to Candace all the things a fair lady should not do... while shifting into an aggressive punk rock tone that completely goes against what a fair lady should do.
  • Meaningful Name: Her middle name is Beckham, which is also the surname of a well name English football (soccer) player, which also happens to be the main subject manner of the episode she appears in.
  • Nice Girl: She reluctantly but still willingly helps Candace act more 'lady-like' and is generally nice to both her and Jeremy.
  • Proper Lady: Is what she's been raised up to be this from an early age.
  • The Rock Star: Downplayed. She has the look and displays shades of this like when her classical music number shifts into a punk rock song, but this is a side of hers she usually keeps well hidden.
  • Tomboy and Girly Girl: Despite what their appearances might imply, Eliza is the girly girl to Candace's tomboy in "My Fair Goalie". Eliza is reserved, elegant and lady-like, as opposed to Candace who utterly fails at being a fair lady and needed Eliza to show her how.


How well does it match the trope?
