[[folder:Linda Flynn and Lawrence Fletcher]]
[[caption-width-right:350:[[CaptainObvious Lawrence is on the left and Linda's on the right.]]]]
-> ''"Ah, it was those corny history references that made me fall for him in the first place."''
->Voiced by: [[Series/SabrinaTheTeenageWitch Caroline Rhea]] (Linda), [[Film/TheRockyHorrorPictureShow Richard O'Brien]] (Lawrence)

Phineas, Ferb, and Candace's parents. Linda is an ordinary suburban mom who somehow remains oblivious to the crazy things Phineas and Ferb does, despite Candace's futile efforts to show her. Lawrence is an eccentric, slightly geeky antiques dealer who sometimes joins in on Phineas and Ferb's hijinks.
%% {{Adorkable}}: Lawrence. See Linda's quote just above.
* AdultsAreUseless:
** Averted for the most part. They are shown to be fairly competent for the most part in the series, in spite of not knowing of Phineas and Ferb's exploits. However, they spend the movie [[FilmWithinAFilm watching a movie]]. Candace's plan to ensure victory for the heroes does involve Linda's participation, but that's more "making use of" adults than adults actively being useful.
** Lawrence occasionally DOES find out about the boys' adventures, but he either remains unphased or (at the most) mildly confused, so he's useless to Candace.
* AmazinglyEmbarrassingParents: Linda in "Does This Duckbill Make Me Look Fat?" and "Meatloaf Surprise".
* ApocalypseMaiden: In many scenarios where Linda does stumble onto what the boys do, the results aren't pretty. ResetButton is a given and a pleasure in these cases.
* BirthdayEpisode: For Linda, "[[ExactlyWhatItSaysOnTheTin Mom's Birthday]]".
* BumblingDad: Lawrence, in a nerdy sort of way.
* CatchPhrase: Linda has "So kids, want some snacks?" or some variation in place of snacks, often pie or cookies.
** "That wasn't very nice." (said when something disappears or changes before she looks, causing her to misinterpret another character's statement as an insult)
** "What does that even mean?" (said in response to [[ItMakesSenseInContext a statement for which she has no frame of reference]])
* {{Cloudcuckoolander}}: Lawrence. In the way that finding out that his sons have literally turned the entire [[ItIsPronouncedTroPAY gare-age]] upside-down or that the television is talking back to him doesn't faze him in the slightest.
* ConcertKiss: In "Dude, We're Getting the Band Back Together".
* DeadpanSnarker: Linda towards Candace, and in general.
-->'''Lawrence:''' "Were you always this sarcastic?"
* FourTemperamentEnsemble: Linda is Sanguine while Lawrence is Melancholic.
* GeekyTurnOn: See the above quote.
* GoodParents: Even though they (Linda especially) are generally unaware of the boys' activities, they do take good care of and are adored by their children.
* HappilyMarried
* HappyDance: Lawrence in "My Fair Goalie". And it is ''glorious''.
-->'''Lawrence''': I'm awesome, you're not. I'm awesome, you're not.
* HartmanHips: Linda.
* HeroesWantRedheads: Lawrence wants redheads.
* HiddenDepths: Linda has some sort of background in astrophysics, but she'd rather keep it a secret. She also used to be a one-hit-wonder, Lindana.
* ILetYouWin: Lawrence to his brother in "My Fair Goalie". Linda convinces him to stop.
* LetsGetDangerous: Lawrence of all people in "My Fair Goalie".
* MsFanservice: Linda sometimes shows signs of this.
* [[NiceGuy Nice Guy and Girl]]: Both are generally quite nice. It's clear where Phineas and Ferb get it from.
* NiceJobBreakingItHero: [[spoiler: Linda is the one who gave Doof the idea of taking over the Tri-State Area.]]
* NoPeripheralVision: Linda. '''SO MUCH.''' UpToEleven in the pilot, where she didn't notice the flaming rollercoaster '''RIGHT IN FRONT OF HER, IN A TREE'''.
* NostalgiaFilter: Lawrence for ''[[ShowWithinAShow Pinhead Pierre]]''. Though he does realize that the Magic Carpet Ride segments are much less exciting than he remembered.
* NotSoAboveItAll: In "My Fair Goalie", Linda is shown is being annoyed by the sibling rivalry between Lawrence and his brother. At first, it looks like she's just irritated by how utterly inane the contests they have are (such as who can hold their breath the longest and who can wear the most shirts at once), but it's later revealed that she's irritated because ''Lawrence keeps letting his brother win''.
-->'''Linda''': Next time, ''destroy him''. Smear the punk. Annihilate him. Make him cry.
* OhNoNotAgain: Linda is this sometimes to Candace.
* OneOfTheKids: Most prominent in "That Sinking Feeling".
* ParentalObliviousness: Justified, as [[ContrivedCoincidence contrived coincidences]] always serve to remove all evidence of the Phineas and Ferb' outlandish creations before Linda can actually see it(or in some cases, just the evidence that they were the ones responsible). Lawrence, though, seems to be oblivious to most things going on around him, and either fully aware or actively participating in many of them.
* ReasonableAuthorityFigure: Lawrence plays this straight, but, at least within the show's context, Linda is actually an aversion. She does genuinely love her sons (and daughter), but she's one of the few authority figures shown who has the ''slightest'' disagreement with the things Phineas and Ferb do. The episode "What Do It Do?" also shows that when the unusual crops up, her ability to go completely bonkers over it can ''even rival Candace''.
** However, Linda's approval of Phineas and Ferb's project in "What'd I Miss?" is likely a sign that she would be more supportive of their projects as long as they're not dangerous.
* SarcasmMode: Linda does this ''a lot'', mostly over Candace's freakouts and failed busts. She assumes whatever she's showing her is imaginary or just going through teen angst.
* SheCleansUpNicely: While Linda is good-looking for her age as both her regular days as Linda Flynn-Fletcher and Lindana, ''Lawrence'' goes from plain and average looking to instant heartthrob making girls faint at the sight of him when he puts on the persona of Max Modem in an attempt to impress his wife.
* SecondLove: To each other. Considering that only Phineas and Candace are blood-related siblings, Lawrence must have had Ferb with someone else before he married Linda, and Linda likewise with her children.
* SnarkToSnarkCombat: Sometimes between Linda and Candace.
* TemporarilyAVillain: Lawrence is hit by a make-everything-evil-izer/inator in "Bullseye!", but he's restored to normal before he does any harm.
* UnwittingInstigatorOfDoom: Played For Laughs with Linda, who dated [[spoiler:Doof]] before meeting Lawrence. Apparently, she's the one who started his fascination with conquering the Tri-State Area.
* VoiceForTheVoiceless: In addition to Phineas, Lawrence seems to speak for Ferb often as well.
* WeirdnessCensor: Linda is possibly the only person in the [[strike:Tri-State area]] [[strike:world]]'''''universe''''' who doesn't know about Phineas and Ferb's inventions and adventures - and given that Phineas and Ferb have ''been to Mars and space on '''several''' occasions'' that's ''not'' an exaggeration as they've literally built stuff in space. The boys themselves are completely unaware of this fact and frequently aid Cadance's attempts to expose them.

[[folder:Francis Monogram]]
[[caption-width-right:320:Is this how he looks when having his portrait done?]]
->''"Ah, good morning Agent P."''
->Voiced by: Jeff "Swampy" Marsh

Perry's immediate superior. It's to him that Perry reports each episode to get a briefing on whatever Dr. Doofenshmirtz is up to. Despite his usually stiff and serious demeanor, it's been shown that he's actually a bit scatterbrained, with his briefings being vague or otherwise unhelpful.
* AlliterativeName: Only when referred to in his official capacity: Major Monogram.
* AsYouKnow: Reminds Perry (and the audience) of OWCA policies when they become plot relevant.
* AscendedExtra: He was originally meant to be nothing more than a [[MrExposition talking head on a screen]] who sent Perry on his missions, but he soon gained an assistant, was eventually revealed to have a son, and had significant roles in multiple episodes (notably "Where's Perry?" and "Save Summer").
* BadassMustache: "Save Summer" even shows him apparently ''growing a new one at will''.
* BewareTheSillyOnes: He may act goofy much of the time, but he can also more than hold his own in a fight.
* BigOlUnibrow: One of his most prominent physical features, even being mentioned numerous times in-universe.
* BunnyEarsLawyer: He can be [[MeanBoss inconsiderate]], [[ManChild juvenile]], and [[{{Cloudcuckoolander}} unfocused]], but "Save Summer" shows how essential his leadership is for the operation of OWCA.
* CharacterizationMarchesOn: In season one, he was a very formal, authoritative no-nonsense boss who behaved in a totally cold demeanor to anyone he spoke to. Since Season 2 onwards, he's a OneOfTheKids eccentric whose mission briefings are never complete without at ''least'' one joke.
* CatchPhrase: "Great googly-moogly!" said whenever he gets surprised.
* {{Cloudcuckoolander}}: Often unfocused, being largely unaware of what Doofenshmirtz is actually up to, easily sidetracked by tangents, and quickly jumping to bizarre conclusions.
* CreatorCameo: Voiced by Jeff "Swampy" Marsh, one of the creators of the show. He is sometimes used as a variation of AuthorAvatar, such as being the one to host clip shows and do episode commentaries while remaining in character.
* DistaffCounterpart: England's spy bureau has a woman of the same age called Inspector Initials.
** Admiral Acronym, the head of Pinky's division.
* DistressedDude: He gets captured by villains now and then, such as in "Summer Belongs to You!", "Where's Perry?", and the Musical Cliptastic Countdown.
* DotingParent: To Monty.
* EmbarrassingFirstName: Francis. He doesn't actually seem embarrassed of at all though, and just seems confused when Doofenshmirtz makes fun of it.
* EnemyMine: In the "Save Summer" special, Monogram temporarily loses his job and became homeless, but he shares Doof's disgust over Rodney's plot to send the Earth into a new Ice Age, as Doof reprimands him for letting L.O.V.E.M.U.F.F.I.N. succeed in taking over the Earth. To that end, Monogram personally aids Doofenshmirtz in stopping Rodney from endangering the Earth.
* FedoraOfAsskicking: Rarely wears it, but he will doff it when it's time to kick some ass ("Where's Perry? part 2")
* FollowInMyFootsteps: Major Monogram was a straight example of his trope and wanted to escape the family legacy and become an acrobat.
* FourTemperamentEnsemble: Choleric (oh so very Choleric)
* GenreBlind: In "Save Summer", he loudly proclaims his optimism on how the OWCA graduation event will go, whereas both Perry and Carl appear to realize that he's TemptingFate. He also has a recurring tendency to jump to highly unusual and illogical conclusions. Averted in the commentary for "The Chronicles of Meap", though he still lacks MediumAwareness.
* GoodCounterpart: To Dr. Heinz Doofenshmirtz, and also to Aloyse von Roddenstein and the members of L.O.V.E.M.U.F.F.I.N..
* GoodIsNotNice: In contrast to Doofenshmirtz's AffablyEvil, Monogram is dedicated to fighting evil, but is often a bit of a jerk.
* HeelRealization: It takes [[spoiler:Carl turning evil and threatening to take over the Tri-State Area for Monogram to realize how much he has been neglecting and mistreating the intern]].
* InnocentlyInsensitive: He often comes across as being inconsiderate towards Carl and sometimes Perry, but is rarely mean on purpose.
* TheLeader: Of one division in the O.W.C.A.
* LetsGetDangerous: As goofy as he usually is, when things get gritty you'll find that he's not an authority figure in the O.W.C.A. for nothing.
* MadeOfIron: Joked with in "Summer Belongs to You", when he claims to have nerves of steel, an iron will, and a series of other metallic-related attributes, concluding that he's "basically 35 percent metal".
* MajorlyAwesome: His "awesome" aspect is rarely shown, but when it is...
* ManChild: Several times. For starters, he ''really'' wants a tacky clown mascot figure to look at while he's having lunch.
* MissionControl: Gives instructions by video call, whether Perry is in his lair or out in the field.
* MisterExposition: His main role, narratively speaking. Since Perry cannot speak, most of what we know about OWCA comes from his exposition.
* NoodleIncident: His time at "the Academy". The RunningGag of him being cut off by abrupt scene changes has also resulted in a few others.
** The only thing we know for sure about his time at the Academy is that he did some sort of favor for Ray Liotta.
* OffhandBackhand: He turns out to be quite adept at this.
* PapaWolf: Seems to have these tendencies toward Carl. When he believes Carl is in danger in "Undercover Carl", it marks the first time he goes into the field himself, with a small army of black choppers and vans in tow, no less.
* PointyHairedBoss: Arguable, but consider this: He refuses to ever give Perry a vacation, even though he only ever pits him against an IneffectualSympatheticVillain that any ''marginally'' competent crimefighter could've handled easily. And you sometimes get the impression that he hasn't bothered to do any research on said villain's activities recently ("Uh...Stop Doofenshmirtz").
** Heck, one time Heinz actually ''called in sick'' to be bothered with their usual routine. Monogram's response ''while he was sick no less'': "How dare he call in sick when everyone already gathered. Screw that, we're going on as planned!".
** Though in his defense, Perry seems to have a good time beating Doofenshmirtz.
* ReasonableAuthorityFigure: Though he often comes across as incompetent, he generally recognizes when situations get serious.
* [[SandInMyEyes Sweating Through My Eyes]]: He denies that he is crying when [[spoiler:Phineas and Ferb bid farewell to Agent P before having their minds wiped at the end of the movie]].
* ThoseTwoGuys: With Carl.
* YouAreTooLate: In the Series Finale, Doof takes over the Tri-State Area by being elected as its first Tri-Governor and wrote a law forbidding Monogram and his agents to thwart him, which forced a depressed Monogram to accept defeat.
----> '''Monogram''': Sorry, Agent P, I just received confirmation that Doof's anti-thwarting legislation is completely legal and official. So, I... guess we're the bad guys now. And I guess this means you're on hiatus... at least until his term is over. Monogram out.

[[folder:Clyde and Betty Jo Flynn]]
[[caption-width-right:320:Did they fit the UglyGuyHotWife trope when they were younger?]]
->'''Clyde:''' ''"Alright, nature lovers! Time for vittles!"''
->'''Betty Jo:''' ''"You wanna go down and embarrass your sister at the park?"''

-> Voiced by: Barry Bostwick (Clyde), Caroline Rhea (Betty Jo)

Linda's parents. They've got a bit of a mischievous streak in them, as seen in their introductory episode "Get that Bigfoot Outta My Face!"
* AlwaysIdenticalTwins: Betty Jo and her sister Lorraine.
* BeehiveHairdo: Betty Jo.
* [[CoolOldGuy Cool Old Couple]]
* HappilyMarried
* HiddenDepths: Part 1 of "Where's Perry?" shows that Clyde has a book on monotreme manners.
-->'''Betty Jo:''' You have a book on monotreme manners?
-->'''Clyde:''' You don't know everything about me.
* HotBlooded: Betty Jo when it comes to Roller Derbys.
* IWasQuiteALooker: Betty Jo looked as good as Linda in her youth.
* NeverMessWithGranny: Betty Jo, especially in the roller derby episode.
* ObfuscatingStupidity: Clyde often plays senile because he loves Betty Jo's notes as seen in "Buford Confidential".
* OneHeadTaller: Betty Jo is noticeably taller than Clyde.
* OneOfTheKids
* {{The Prankster}}s: In "Get That Bigfoot Outta My Face!"
* SarcasmMode: Betty Jo to Candace.

[[folder:Reginald and Winifred Fletcher]]
[[caption-width-right:350:It appears that the Fletcher family looks are hereditary.]]
->'''Reginald:''' ''"The Flying Fishmongers shall jump again!"''
->'''Winifred:''' ''"Dinner's at 19:00. That's 7:00 for you Yanks!"''

-> Voiced by: Creator/MalcolmMcDowell (Reginald), Jane Carr (Winifred)

Lawrence's thoroughly British parents. Reginald was a bit of a thrill-seeker in his youth, and performed as a stunt motorcyclist known as "The Flying Fishmonger".
* BadassGrandpa: Reginald. See RetiredBadass.
* {{Bookworm}}: Winifred is hinted to be this in "Elementary Dear Stacy" due to her vast collection of Sherlock Holmes books.
* [[CoolOldGuy Cool Old Couple]]
* HappilyMarried
* HighClassGlass: Reginald.
* RetiredBadass: Reginald used to do daredevil stunts as The Flying Fishmonger. He briefly takes up the mantle again with Phineas and Ferb in "The Flying Fishmongers".

[[folder:Charlene Doofenshmirtz]]
[[caption-width-right:299:She's loaded, ya know. Ka'ching!]]
->''"I kept the name!"''
-> Voiced by: Creator/AllisonJanney

Dr. Doofenshmirtz's ex-wife. Not much is known about her, other than she's rich and that she and Heinz get along pretty well, despite some back-and-forth snark. Despite her daughter's insistance, [[CassandraTruth she doesn't believe that her ex is an evil scientist]].
* AdultsAreUseless: She refuses to believe that anyone (especially Doof) can be evil in real life. Even when Vanessa describes Doof's daily routine as an evil scientist that usually happens, Charlene passes this out as fiction, believing that Vanessa is being overly dramatic, much to Vanessa's frustration.
** However, there were a few times when Charlene was impressed with what Doof has done. In "Thaddeus and Thor" she was briefly surprised to see that Doof created a machine to help him cope with his poor kicking skills as he pulled a good kick during the Doofenshmirtz family reunion. In "Bee Day", she complimented Doof for using bee pheremones to make himself look more attractive. In "This Is Your Backstory", she is even aware that Doof built a giant robot named Norm to serve as his assistant and complimented him for his tuxedo design.
* AloofDarkHairedGirl: [[LikeFatherLikeSon Like Mother, Like Daughter]] after all.
* AmicableExes: She snarks at Heinz occasionally regarding his odd money spending habits and his ineptitude at building things when they were together, but she is genuinely friendly with him most of the time, most evident in her near-constant attempts to get Vanessa to warm up to him. Apparently their marriage ended because they "both wanted different things."
* BoyishShortHair
* DeadpanSnarker: Toward Doof, and sometimes Vanessa.
* {{Fiction 500}}: Constantly implied and explained as the source of money for Doof's antics.
* GoodParents: Just like Doof, she does take good care of and is adored by Vanessa. She even encouraged her to promote to charity once in a while.
* {{Meganekko}}: Never seen without glasses that reflect her serious personality.
* OhNoNotAgain:: Charlene is this sometimes to Vanessa.
* [[UglyGuyHotWife Ugly Guy, Hot Ex-Wife]]: To Doof.

[[folder:Love Händel]]
[[caption-width-right:350:Remember when all bands in TheNineties dressed like this?]]
->'''Danny:''' ''"See? Music does change lives."''
->'''Bobbi:''' ''"I just play bass in the background. Nobody even remembers me."''
->'''Sherman:''' ''"Hey, I do have rhythm!"''

-> Voiced by: Jaret Reddick (Danny), Creator/CarlosAlazraqui (Bobbi) and Steve Zahn (Sherman)

A hair metal band from the early nineties, they were a favorite of Linda and Lawrence until the band split up. As an anniversary gift to their parents, Phineas and Ferb spend the episode "Dude, We're Getting the Band Back Together!" trying to convince them to get together for a reunion concert.
* AdultsAreUseless: The only adults in the movie to (somewhat) avert this. More so in a deleted scene where Danny gets to take out at least one Normbot... [[CrowningMomentOfAwesome with a simple]] OffhandBackhand!
* AllDrummersAreAnimals: Subverted with Sherman, who went on to become a librarian and is generally pretty chill.
** To the point where even on future tours he still wears his collared shirt and tie, while the other two are in costume (as seen in ''Across the 2nd Dimension''). He's shown in his classic outfit at the end of "Rollercoaster - the musical!" though.
* AmbiguouslyGay[=/=]CampGay: Bobbi Fabulous, the bassist.
* AndShowItToYou: Sung about and done so with a Normbot in "Robot Riot"... [[WhatCouldHaveBeen at least in a deleted scene]].
* AutobotsRockOut: Their main role during the FinalBattle in the movie is to provide live musical accompaniment.
* BareYourMidriff: Sherman, when he was still going by Swampy.
* FakeBand
* HeavyMetalUmlaut
* InformedAbility: Bobbi Fabulous is supposed to be an incredible hairstylist, but he only seems capable of producing the exact same hairstyle over and over again, regardless of who he's putting it on.
* MrFanservice: They've got quite a little troop of [[YaoiFangirl fangirls]] on deviantArt.
* MyspeldRokband
* NoodleIncident: "Albuquerque '93".
** "Detroit '84", but at least we know ''that'' involved [[NoodleImplements juice and some packing tape.]]
* OffhandBackhand: Danny does this to a Normbot in a deleted scene.
* ThePowerOfRock: "Danny's Song" is all about this.
** Hell, Danny in general is all about this. "It's only my ''life''", indeed.
* TrueCompanions: After they're reunited in their introductory episode, they're almost never seen apart again.
* {{Tuckerization}}: The band members are all named after and drawn to look like series creators Dan Povenmire, Jeff "Swampy" Marsh, and Bobby Gaylor.

[[folder:Roger Doofenshmirtz]]
[[caption-width-right:320:Would you vote for him?]]
->''"Yes, it's so easy to blame the guy in charge."''
-> Voiced by: John O' Hurley

Dr. Doofenshmirtz's "goody two-shoes" younger brother, and frequent target of Heinz's animosity for being the favored son and generally out-performing him at everything when the two were growing up.
* HundredPercentAdorationRating: Everyone from his parents to the voters to [[ItMakesJustAsMuchSenseInContext giant squids]] love him, with the sole exception of his brother.
* TheAhnold: He's got the chiseled body of a typical action star.
* AlwaysSomeoneBetter: For Heinz.
* BigLittleBrother: He is definitely more mature and more physically impressive than [[ManChild Heinz]], though he is in fact the younger sibling.
* JerkWithAHeartOfGold: He's rather mean to Heinz, but he's helped others and is hinted to be why Danville is a great place to live. Once he even spent twenty years trying to restore his brother's painting.
* ObliviouslyEvil: In most of Heinz's {{Freudian Excuse}}s that involve him, Roger doesn't seem to realize what his actions were doing to his brother, with even his younger self's actions in "Make Play" making at least some sense when you consider how much his parents pampered him. In "Magic Carpet Ride", the only time he's part of a FreudianExcuse when he's older than a child, he's genuinely regretful of how his actions hurt Heinz, even if it wasn't completely his fault.
* OnlySaneMan: Of the Doofenshmirtz family, anyway, considering how he was the only one to notice that Heinz only wants a little respect, and acknowledges that he does kinda deserve it.
* PatientZero: Roger Doofenshmirtz plays this role in Night Of The Living Pharmacist after his brother's scheme goes horribly right.
* PetTheDog: He spent 20 years remaking his older brother's painting that he had accidentally ruined as a kid. Unfortunately, Heinz ruins this one too. Also, whatever the issues he and his brother may have, he clearly doesn't let them affect his treatment of his niece, as Vanessa says that she likes "Uncle Roger".
* SleazyPolitician: Roger is something of a mild example. He seems to care more about his popularity than the lives of others, and even makes his brother the fall guy in "The Beak".
* SmallNameBigEgo: Well, "Doofenshmirtz" isn't a small name at all, but the idea still stands.
* VillainWithGoodPublicity: {{Downplayed}}. He's not a villain, but a complete jerk. Though how much of a jerk [[DependingOnTheWriter tends to change from episode to episode.]] On the one hand he's implied to be part of the reason Danville is such a nice place to live, having done a lot of genuinely good work and helped a lot of people (before becoming Mayor, he once got the key to the town from the then Mayor), and his niece Vanessa says she likes him. On the other hand, he's rather full of himself, lazy when he can get away with it, and often quite a jerk to his brother ("And I've already wasted half the morning not caring at all about being on time for our golf game.")... then again, he spent twenty years restoring his brother's painting he accidentally ruined (though, that may have just been because he respected the quality of the work, but he did go to lengths to credit Heinz in his speech), so it's a really mixed bag.

[[folder:Aloyse von Roddenstein]]
[[caption-width-right:300:"Erase this article or a new Ice Age is coming!"]]
->''"Nobody talks to my hand that way!"''
-> Voiced by: Joe Orrantia

Another mad scientist and rival within L.O.V.E.M.U.F.F.I.N. to Doofenshmirtz.
* BaldOfEvil: Evil and prominently bald.
* BigBad: In "Recap/PhineasAndFerbSaveSummer".
** Given his status as the (apparent) leader of L.O.V.E.M.U.F.F.I.N. and the fact that he's an enemy to both Perry and Doofenshmirtz, you could make the argument that he's this for the whole series.
* CharacterDevelopment: During his previous appearances, he was shown to be as goofy as Doofenshmirtz, that is until "Save Summer", where he becomes completely psychopathic in nature by revealing his ruthless plan to bring in a new Ice Age that would endanger the entire world population, an act that everyone (including Doofenshmirtz) finds to be very disturbing.
* CreatorCameo: Voiced by one of the writers on the show.
* DiabolicalMastermind: Upon hearing of Doofenshmirtz's successful scheme of moving the Earth to an early autumn, Rodney takes the opportunity to exploit the event, effectively becoming the brains behind L.O.V.E.M.U.F.F.I.N.'s plot to rule the Earth. He arranged his fellow villains to capture nearly all of O.W.C.A.'s agents, hold the world for ransom, and contact the world leaders to meet their demands by any means.
* EvenEvilHasLovedOnes: In "A Real Boy", Rodney is shown to care for his son named Orville, whom he praises for his assistance in helping him create his inizors. Also, in "Love at First Byte", Rodney is shown to be overprotective towards his robot assistant named Chloe, as he forbids her to hang out with Doof's robot Norm because of his rivalry with Doof (despite Norm and Chloe's love for each other due to their dancing skills).
** However, the "Save Summer" special completely subverts all of this as Rodney was willing to put the Earth into a horrible fate that would endanger the entire world population, so it may be clear that his relationships with his son and robot assistant are very insincere and of no regards to him anymore (and even when he was praising his son, it was more about taunting Doof than anything).
%%* EvilGenius
* [[EvilCounterpart Eviler Counterpart]]: To Doofenshmirtz. Rodney's just as goofy, but lacks Doof's redeeming qualities.
** Also, to an extent, to Phineas and Ferb, who strive to make summer more fun for everyone while Rodney plots to destroy summer for his own selfish ends.
%%* EvilIsHammy
%%* EvilIsPetty
* EvilerThanThou: Unlike the other villains in the show, underneath his goofy exterior, Rodney was an absolute psycho with no concern for anything but himself, having absolutely no morals when it comes to power.
%%* FauxAffablyEvil
%%* FourEyesZeroSoul
* FluffyTheTerrible: Literally - His pet piranha is named Fluffy.
* GadgeteerGenius: Like Doofenshmirtz, he invents many contraptions to further his evil goals. He calls his "inizors".
* GoodParents: Subverted, [[spoiler:as he cared more of his desire to rule the world than the well-being of his son.]]
* HarmlessVillain: Up until "Save Summer", he was shown be no more effective a villain than Doofenshmirtz. And even then he was capitalizing on one of Doof's schemes.
%%* HerrDoktor
* InSeriesNickname: Addressed as "Rodney" by Doofenshmirtz because of his long full name, something which he later gets used to.
* {{Jerkass}}: Always attempts to downplay Doofenshmirtz in the art of evil; even when Doof calls him a jerk for trying to steal one of his inators, Rodney himself takes great delight in being called one. It would further intensify when he attempted to move the Earth into an ice age.
* JerkWithAHeartOfJerk: During the final fight, Rodney attempts to talk Doof out of fighting and suggests a team-up that would benefit them both, but seconds later, he tricks Doof into looking the other side and pushes him out of the way to finalize his plan for a new Ice Age.
--->'''Rodney''': Oh, this is just ridiculous. You and I should just- oh, look. A horse in a bookcase.\\
'''Doof''': A what? (gets pushed away by Rodney) WHOA!\\
'''Rodney''': HA! Now to move the Earth into a new ICE AGE!!! (activates his machine)
* MadScientist: As an evil inventor.
* NearVillainVictory: During the climax, Rodney gets into a fight against Doofenshmirtz over the machine's controls and pushes him away before activating the machine to move the Earth ''further'' away. To ensure of this, Rodney deliberately disables the reverse switch and self-destruct button, resulting him to be whomped down by an angry Doofenshmirtz for dooming the Earth. Doofenshmirtz would later disable the machine by making it fall off the roof (with the help from Perry, Major Monogram, Carl, and Monty) to save the Earth.
* NonActionBigBad: Though he helps capture the O.W.C.A. agents by trickery, even Doofenshmirtz can defeat him when it comes to an actual fight.
* NotSoHarmlessVillain: Along with the rest of LOVEMUFFIN, he succeeds in neutralizing most of OWCA and nearly plunges Earth into another ice age in "Save Summer," putting him in a category with [[spoiler: Alt-Universe Doofenshmirtz, Alt-Universe Charlene, and Evil Carl]] as villains who legitimately serve as serious threats. However, unlike the others, Rodney has no morals whatsoever.
* ObviouslyEvil
* OverlyLongName: Aloyse Everhart Elizabeth Otto Wolfgang Hypatia Gunther Galen Gary Cooper von Roddenstein.
* PsychopathicManChild: As immature as Doofenshmirtz, Rodney has been shown to be far more ruthless, as he was willing to endanger the Earth for his own selfish desire to show who's in charge.
* TheRival: To Doofenshmirtz.
%%* SimpletonVoice
* SitcomArchnemesis: To Doofenshmirtz.
* SmallNameBigEgo: He constantly mocks Doofenshmirtz as a failure, but not only is Rodney no more successful, but the only schemes we see him engage in are ones that he stole or piggy-backed from Doof.
%%* SmugSnake
* TheyCallMeMisterTibbs: Downplayed in later episodes though.
* VileVillainSaccharineShow: As much as it goes in "Save Summer", he cared less about billions of lives being put at risk by his plan to send the Earth into a new Ice Age than about making some petty point about being in charge, even going so far to disable the reverse process on his machine to ensure that his plan would succeed.
--->'''Doof''': Okay, I had time to think it over, and we need to put the world back. I, for one, do NOT want to live in a world full of perpetual winter. Scoot over, Rodney. (attempts to reprogram the machine)\\
'''Rodney''': Your betrayal doesn't surprise me, Heinz. STEP ASIDE! (gets into a fight with Doof over the controls while the platform raises up)\\
'''Doof''': Wha.... what are you doing?!\\
'''Rodney''': Just to show you who's boss! I'M GOING TO MOVE THE EARTH EVEN FURTHER AWAY FROM THE SUN!!


[[folder:Esmeralda Poofenplotz]]
->''"I can't very well take over the world until I'm drop-dead gorgeous."''
-> Voiced by: Amanda Plummer

Yet another mad scientist, the nemesis of Isabella's pet chihuahua Pinky.

* AlliterativeName: Though not so when her first name, Esmeralda, is included.
* ArchEnemy: To Pinky the Chihuahua.
* {{Cloudcuckoolander}}: She thinks eating royal jelly will make her the queen of the world... and give her a large abdomen for laying eggs, but she claims she can live with that. She soon learns the hard way after realizing that her hypothesis is faulty.
* CatchPhrase: Has one whenever her plans get foiled by Pinky, similar to Doofenshmirtz's.
--->'''Poofenplotz:''' ''"Curse you, Pinky the Chihuahua!"''
* DistaffCounterpart: Dr. Doofenshmirtz, but an even less competent one according to Doofenshmirtz himself.
* EvilIsPetty: Thinks she should look her best before she can begin her evil plans. As a result, her schemes rarely even get ''started''.
* {{Faceship}}: She seems fond of using these.
* FailureIsTheOnlyOption
* GenderMisdirection: Brazilians don't have a gender-neutral equivalent for "Professor". When the episode where Professor Poofenplotz was first mentioned was translated for Brazilian audiences, they used the masculine equivalent. Then the episode "Isabella and the Temple of Sap" revealed Professor Poofenplotz was a woman.
* HarmlessVillain: Even ''Doofenshmirtz and the members of L.O.V.E.M.U.F.F.I.N.'' think she's not evil enough to join their organization because of her silly schemes.
* HartmanHips
* LaughablyEvil: So much that it makes Doofenshmirtz look like a real threat.
* MadScientist
* ObviouslyEvil
* ShootTheMessenger: Poofenplotz literally shoots the woman who was stocking shelves at the beauty store because when asked, the stocker informed her that "Stiff Beauty" had been discontinued by the manufacturer. However, the gun in question didn't kill the woman, it just sent her to another dimension.
* VillainOfAnotherStory: Despite having few appearances in the series, it is implied Pinky has to stop her regularly. The fact that she's even more of a HarmlessVillain than Doofenshmirtz probably helps prevent her from taking part in the plot on a bigger scale.
* [[MinionWithAnFInEvil Villain With An F In Evil]]: Her evil schemes are ridiculous even compared to Doofenshmirtz's.
* ZanyScheme: For starters, see her scheme in "Bee Story", in which she plans to eat enough royal jelly for her to somehow be crowned queen of the world.
