"Hi, Phineas. Whatcha doin'?"
"Calm down, girls. Have you forgotten who we are? We're Fireside Girls Troop 46321 and we never give up!"
"Oh, you're just too stressed. You should take a moment to relax and enjoy it."
Isabella Garcia-Shapiro is the neighbor and best friend of Phineas and Ferb. Isabella has a crush on Phineas; however, she doesn't tell him. She's the leader of Fireside Girls Troop 46231, and often volunteers to help in Big Ideas, usually with her troop being involved.
Isabella Garcia-Shapiro was born to a Jewish Mexican mother Vivian Garcia-Shapiro and an unnamed father. At some point in her life, she met and became friends with Phineas Flynn and Ferb Fletcher. The friendship with Phineas eventually turned into a crush.
Though it is unknown when, Isabella joined the Lil' Sparks and later the Fireside Girls where she worked her way up to becoming a Troop leader.
Isabella lives in Danville on Maple Drive with her mother in the house across the street from the Flynn-Fletcher house. She frequently participates in Phineas and Ferb's projects, assisting in construction and maintaining order.
When on duty, Isabella works diligently upholding her position in the Fireside Girls and earning accomplishment patches. She is currently the leader of Fireside Girls Troop 46231. The troop members are Gretchen, Milly, Ginger, Katie, Holly, and Adyson, with which she is considered not only a leader, but a great friend.
PersonalityIsabella is cheerful, fearless, quick-thinking, sweet, optimistic, caring, and easy to get along with. She is always eager to help Phineas and Ferb's Big Ideas. When she participates with Phineas and Ferb in their endeavors, it's either for the fun of it, or a way to simply be with Phineas.
Isabella is sympathetic and aids people who are in need of help. This has been demonstrated when she showed concern for Candace, who was too nervous to call Jeremy and ask him out ("Out to Launch"), and when she snapped Phineas and Ferb out of their hypnotic dullness. ("Phineas and Ferb Interrupted")
Being a Fireside Girls Troop Leader, Isabella is a very capable leader. She is level-headed and responsible in the face of emergencies and dislikes being told what to do by anyone, with the exception of Phineas.
As nice as Isabella would seem, she can get angry. One way her temper has been flared is when someone else uses her catchphrase; in such a scenario, she expresses annoyance and often confronts the violator physically. However, she is fine whenever Phineas uses it.
Another is when she isn't a subject of attention. Isabella enjoys attention, she openly displays discontent when she feels she isn't receiving enough of it. She has shown this when Phineas expressed seeing Meap as cute but not her ("The Chronicles of Meap"), and when her Li'l Sparks men-tee, Melissa, showed Candace more attention and admiration than she did with her. ("We Call it Maze")
Isabella has long, black hair with thin blue hi-lights, curtan-like bangs and a round bottom, an oval shaped head with a flat top, and dark blue eyes.
As a baby, she wore a pink t-shirt and had her hair tied up in a high pointed ponytail.
Currently, she wears a pink dress with a white T-shirt underneath and a deep purple belt, white socks and pink shoes with white laces. The pink bow in her hair is thought to be her trademark, and she has only been seen without it on a few occasions, but not without it on her head.
Her Fireside Girls uniform is the same format as her normal clothing, with the exception that her dress is half orange and half brown. She wears an orange beret with a red bow in the front. Underneath is a red bow. Her belt is red, and she has a light yellow accomplishment sash with three shaped patches consisting of a teal diamond, a teal oval and a gold triangle from top to bottom, respectively. Her shoes are red with yellow laces.
For swimming, her swimsuit consists of a pink, one-piece bathing suit and her trademark pink bow. For winter, she switches to a more mulberry colored dress with white turtleneck underneath, purple leggings and off-white fur boots, and wears a purple hat with pale pink bow, purple coat, pale pink scarf (loose wrap), pale pink mittens, and white boots while outside in the snow. Her inside winter outfit is the same as her summer outfit, but with purple pants ("Happy New Year!"). Her pajamas are light purple with darker purple stripes, and she wears a purple bow.

Skills and Abilities
Isabella has displayed numerous skills and abilities. She appears to be very physically capable, being a fast runner ("Candace Loses Her Head", "Journey to the Center of Candace"), and also remarkably strong, having been able to hurt Buford by elbowing him and crushing a pencil. ("Out of Toon", "Phineas and Ferb Summer Belongs to You!")
Isabella has demonstrated exceptional musical ability. She's an excellent singer ("S'Winter", "The Magnificent Few", "The Ballad of Badbeard", "Phineas and Ferb Summer Belongs to You!", "Wizard of Odd", "Rollercoaster: The Musical!", etc.) and can play various musical instruments including:
- The tambourine ("The Fast and the Phineas," "Don't Even Blink", etc.)
- The trumpet ("Don't Even Blink")
- The bass guitar and key-tar ("Tip of the Day", "Gaming the System," "Oh, There You Are, Perry", etc.).
- The saxophone ("Take Two with Phineas and Ferb: Cedric the Entertainer")
- The violin ("Out to Launch", A Phineas and Ferb Family Christmas")
Though admitting to being too young to legally drive, Isabella possesses remarkable knowledge over the anatomies of automobiles ("The Fast and the Phineas") and is capable of flying small jet aircraft, such as a fighter jet ("Phineas and Ferb Christmas Vacation!").
She can also assume the role of a business agent, and does the job exceptionally well. ("Lights, Candace, Action!")
Isabella has shown that she is very clear headed during emergencies. She demonstrated this when she saved Phineas from a perilous fall ("One Good Scare Ought to Do It!") and when she defeated a giant video game Buford with a digital camera. ("Gaming the System")
Isabella has a monopoly of the catchphrase, "Whatcha doin?", and allows no one else besides Phineas to use it. She can sense it when it is being used would be extremely displeased upon knowing anyone else used it. She would often confront that person physically, as she did with Buford. ("Out of Toon", "Phineas and Ferb Christmas Vacation!", "Suddenly Suzy", "Tri-Stone Area")
"Well, that's not the Phineas Flynn I fell in... to this situation with."
- Main article: Isabella and Phineas's relationship
She has romantic daydreams about Phineas and believes she will one day marry him or Ferb, but she never says that to him. However, she feels sad when Phineas can't notice her flirting with him ("Phineas and Ferb's Quantum Boogaloo", "Isabella and the Temple of Sap", "Out to Launch", "Comet Kermillian", "Candace's Big Day", etc.). She admitted that the only reason for which she says her trademark phrase ("Whatcha doin'?") is to capture Phineas's attention and love ("Isabella and the Temple of Sap", "Rollercoaster: The Musical!"). During one of Phineas' birthdays, she used the fact that she was editing videos of Phineas for the video presentation to trim the videos down to just one word and form a sentence that relates to her having a crush on Phineas. An example of this would be: "We'll - be - together - forever, - Isabella." ("Phineas' Birthday Clip-O-Rama!")
One example of this is when Isabella and Phineas were alone in Paris looking for airplane parts, and Isabella was trying to be romantic with him, but Phineas seemed utterly oblivious to her. Then when the boat crash landed on the deserted island and Phineas was trying to find something to fix the boat, Isabella began to cry because Phineas didn't notice her and she would've given anything for Phineas to sit down next to her and enjoy the sunset. Then Phineas ran up next to her, having a small mental breakdown, desperately thinking of an idea to get off of the island. Figuring that none of the ideas would work, he gave up hope entirely and sat down with Isabella to enjoy the sunset with her. Seeing how broken Phineas was, Isabella realized that this wasn't the amazing, confident kid she had "fallen in this situation" with, so she gave him a talk, almost admitting her love for him in the process, but she quickly caught herself and said something else. She then mentioned Ferb's map and Phineas thanked her for the inspiration with a hug, leaving her in a trance. Later when they make it back to Danville, Isabella hugs Phineas for regaining his confidence to achieve his goal. Less than 30 seconds later, they sing a duet in which Phineas holds Isabella's hands several times and also showing signs that he has feelings for her as a friend ("Phineas and Ferb Summer Belongs to You!").
When Phineas constructs a device to find cute things to search for Meap, he says he took Isabella's into account and adjusted the settings accordingly ("The Chronicles of Meap"). When he puts the settings back to normal, the device overloads from an excessively cute signal.She uses her position as Fireside Girls troop leader to stay near him and participate in his Big Ideas, under the guise of earning the "Help Thy Neighbor" patch (which she has earned at least 52 times). It is unsure whether Phineas has the same feelings towards Isabella, but mostly he seems oblivious. Phineas feels bad about ditching her, and also says that he cannot tell her he is The Beak because she is "close to him" ("The Beak"). Phineas is sometimes worried about Isabella getting hurt ("Gaming the System", "The Beak" , "Der Kinderlumper") Also, when Isabella tells Phineas he is brave, he replies with, "You were too!" She learns that she will be aunt to Candace's children. Although who she married was unknown, it will most likely to be Phineas or Ferb, since Phineas and Ferb is now being shown returning Isabella's feelings. She sometimes disguises her affection for them (but very rarely) like hugging him in a crowd when everyone is hugging Perry, Isabella hugs Phineas and instead of Perry ("Oh, There You Are, Perry").
When Isabella and several others were lined up to have their memories of witnessing Perry as a secret agent erased, she kissed Phineas less than a second before the Amnesia-Inator was to be activated. Right afterwards, Phineas objected to having their memories erased only to be ignored ("Phineas and Ferb The Movie: Across the 2nd Dimension").Candace, she has outright stated that Ferb is Phineas' stepbrother ("Rollercoaster"). Unlike her time with Phineas, Isabella shows no romantic interest in Ferb although she does like him. However, after time-traveling to the future, she learned that she might marry either Phineas or Ferb ("Phineas and Ferb's Quantum Boogaloo"). Upon this discovery, Ferb turned around and winked at Isabella, who was stunned at the possibility that she may marry someone else other than Phineas. This may indicate that Ferb may harbor a bit of affection for Isabella, or that Ferb just fancies himself a ladies' man ("Thaddeus and Thor"). It is also possible he was simply teasing her. Ferb is slightly irritated and gets mad when Phineas gets all of Isabella's attention and praise for being a superhero ("The Beak"), but it can be just the thought of him being the one who controls the lower half and saves Danville from the falling sign, but Phineas gets all the attention.
When they were stranded on the uncharted island, Ferb listened while Isabella talked about Phineas not noticing her and offered her a handkerchief when she started crying. He knows about Isabella's crush on Phineas and he also walked away when Phineas came to leave them alone. He may might not have any affection to Isabella however he knows he might get married with her. ("Phineas and Ferb Summer Belongs to You!", "The Doof Side of the Moon"). It is most likely that he does not have affection for Isabella since he has more affection for Vanessa Doofenshmirtz ("I Scream, You Scream"). Ferb has also demonstrated awareness of Isabella's affection for Phineas; after Ferb helped Phineas throw a party for Isabella, when Phineas offered her ice cream with Ferb, he left to have Phineas and Isabella have some alone time together. Isabella was pleased and both bumped fists. ("Happy Birthday, Isabella") It is very plausible that Ferb did this because he knows that either he or Phineas will marry Isabella and he doesn't have any romantic feelings for her.
- Main article: Baljeet and Isabella's relationship
Isabella is friends with Baljeet. They hang out on occasion, usually when they are brought together by Phineas and Ferb's Big Ideas. She won a bet against him on who would win the fight between Buford and the squid ("Voyage to the Bottom of Buford"). Though when trying to find the purpose of a machine Baljeet did jump at the chance to have a romantic dinner with Isabella, even a staged one. Isabella told him he ran to the table "...like a crazed bull" ("What Do It Do?"). This is also hinted when Baljeet asked Isabella if he made a good Phineas, she responds with "No, no you weren't" ("Not Phineas and Ferb"). When Phineas and Ferb built a Super Computer, Isabella is seen thinking about Phineas on the super computer. This makes Baljeet mad, showing he may have a crush on her ("Ask a Foolish Question"). While attempting to climb Danville Mountain, Isabella shows significant enthusiasm for Baljeet's eagerness to perform the task without the help of any Flynn-Fletchers' inventions, which stands in contrast to the attitude of Ferb and, especially, Phineas ("Bully Bromance Breakup").
- Main article: Buford and Isabella's relationship
When they play sports or games, Buford usually mocks her for being a girl, and therefore less of a competitor in his eyes. Isabella takes this very seriously and refuses to let Buford beat her ("Got Game?", "Brain Drain"). When she saw Buford crying about his lost goldfish, she expressed concern and worry about him ("Voyage to the Bottom of Buford"). She also stood up to the video-game boss (designed in Buford's image), and defeated him after he threatened Phineas ("Gaming the System"), though technically this was not the real Buford. When Buford became hypnotized by Phineas and Ferb's boringness, Isabella quickly revived him by a quick slap in the face ("Phineas and Ferb Interrupted").
- Main article: Candace and Isabella's relationship
Isabella and Candace are good friends. They both know about each other's respective crushes and share advice and experience ("One Good Scare Ought to Do It!", "Out to Launch", "Phineas and Ferb's Quantum Boogaloo", "Phineas and Ferb-Busters!", "Phineas and Ferb Summer Belongs to You!"). While in Paris, however, Isabella felt and displayed envy of the time Candace was able to spend with Jeremy. ("Phineas and Ferb Summer Belongs to You!")
When Isabella was delighted to know she was being called 'aunt' by Candace's future children, initially believing she'd grow up to marry Phineas, Candace responded saying there was the possibility it wouldn't be Phineas she would marry, but rather Ferb ("Phineas and Ferb's Quantum Boogaloo"). Candace teamed up with Isabella to beat Buford and Baljeet ("Got Game?"). Isabella, Phineas, and Ferb also helped Candace get a ticket to the Paisley Sideburn Brothers Concert ("Fireside Girl Jamboree"). Even though they like each other in general, Isabella was mad at Candace when Melissa was more interested in Candace's achievements than Isabella's, yet they became reconciled when Candace admitted that if it were not for Isabella, she would have never gained 50 Accomplishment Patches in a single day ("We Call it Maze").
Candace doesn't try to bust Isabella when Baljeet and Buford pose as Phineas and Ferb, even though she acknowledged that Isabella was in the backyard ("Not Phineas and Ferb"). When she is sad or worried, including when her dog Pinky was missing, Candace acted like a big sister to her as she tried to cheer her up, letting her know that Pinky will turn up like Perry does ("Where's Pinky?").
As the troop's leader the Fireside Girls always follow Isabella's orders, always ready and willing to do whatever it takes to help their leader in helping Phineas and Ferb, even risking themselves to do it. Although the girls are loyal to Isabella, and have earned many a badge in helping the boys, they have voiced that they've collected more than fifty of the 'Help Thy Neighbor' patch because of it. They're also aware of Isabella's crush on Phineas and her desire to marry him, and they jokingly tease her for it ("Isabella and the Temple of Sap"). Even so, they remain friends with the boys and squealed with delight when Phineas invited Isabella on a romantic cruise ("That Sinking Feeling").
