Isabella Garcia-Shapiro

Isabella Garcia-Shapiro is the neighbor and best friend of Phineas Flynn and Ferb Fletcher. She lives in Danville on Maple Drive, across from Phineas and Ferb's house, with her mother, Vivian Garcia-Shapiro. She has a huge crush on Phineas (though he doesn't seem to notice it) and spends most of her days participating or helping with his and Ferb's projects. She also spends time trying to earn Fireside Girls patches. She is also great friends with the members of her troop in the Fireside Girls.

Biography
Isabella Garcia-Shapiro was born of a Hispanic mother and a Jewish-American father. At some point in her life, she met and befriended Phineas and Ferb (with the former becoming her crush). She also joined the local troop of Fireside Girls, and became the troop leader.

Isabella lives in Danville on Maple Drive, across from Phineas and Ferb with her mother, Vivian Garcia-Shapiro. She spends most of her days participating or helping with their many projects. She also spends time caring for her dog Pinky or trying to earn Fireside Girls patches. She is also great friends with the members of her Fireside Girls troop, Gretchen, Milly, Ginger, Katie, Holly, and Adyson.

Personality
Isabella is happy, fearless, sweet, caring and spirited, eager to help with any of Phineas and Ferb's Big Ideas. Most of the time it's for patches, or simply because she has a crush on Phineas. She is mostly optimistic, but she also cares for, and worries about people at times. Being the leader of Fireside Girls 46231, she has fantastic leadership and organizational abilities, though she'll follow Phineas's orders as well. Isabella can get a little jealous and frustrated at some "thing" (Meap) or someone that Phineas gives a lot of attention. Isabella has shown at least twice that she has a devious streak, taking advantage of a situation to her the own benefit. These instances include her immediately jumping on Baljeet's wager of squid versus Buford. She also buys a play with the carny Shady Joe when the bowling ball knocks down all the pins (along with the stand), although Shady Joe is cheating by having the pins taped onto the shelf.

Phineas Flynn
Isabella has a huge crush on her neighbor/best friend Phineas. She has many romantic daydreams about him and also believes she will one day marry him, but she gеts angry if he does not notice her or is oblivious to her hints, which is generally whenever she acts romantically around him ("Phineas and Ferb's Quantum Boogaloo", "Isabella and the Temple of Sap", "Out to Launch", "Comet Kermillian", "Candace's Big Day", etc.). She cutely greets him with the phrase "Whatcha doin'?" She has even directly referred to Phineas as "The very thing she lives for." ("Isabella and the Temple of Sap") Also, Isabella revealed in the song 'Whatcha Doin'? that she is always dying to come over to his house to see him and ask 'Whatcha Doin'?' and that she specifically says it to Phineas and not Ferb. Isabella swoons for "The Beak " many times during "The Beak's Theme Song", not realizing that it was still Phineas she was swooning for.

One example of this is when Isabella and Phineas were alone in Paris looking for parts, and Isabella was trying to be romantic, but Phineas seemed very oblivious to her. Then when the boat crash landed on the deserted island and Phineas tried to find something to fix the boat, Isabella began crying because Phineas didn't even take notice of her and she would have 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 kid she had fallen in love with, so she gave him a pep talk, and 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. Not even 30 seconds later they sing a duet (Summer Belongs to You!) with Phineas taking her hand several times and also showing several signs that he returns her feelings for him ("Phineas and Ferb: Summer Belongs To You!").

However, when Phineas constructs a device to find cute things to search for Meap, he says he had took Isabella's cuteness 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 strong cute signal from her. She uses her position as Fireside Girls troop leader to stay near him and participate in his Big Ideas, under the guise of earning "Help Thy Neighbor" patches. 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"). Also, when Isabella tells Phineas he is brave, he replies with, "You were too!" She learns that she will be an aunt to Candace's children. Although who she married was unknown, it will likely be Phineas, since Phineas is now being shown returning Isabella's feelings. She sometimes disguises her affection for him (but very rarely) like hugging him in a crowd when everyone is hugging Perry, Isabella hugs Phineas instead ("Oh, There You Are, Perry"). In "The Great Indoors", Phineas helps Isabella get patches after rain spoils her plans to get them, which had made her sad. The rain was caused by Heinz Doofenshmirtz's Rain-inator. In "Canderemy", Isabella wanted Phineas to go to a sold-out Stumbleberry Finklebat movie, but Phineas interrupted her so he could finish his robo-dog(as seen in the short version of Today is Gonna Be a Great Day). At the end Phineas goes with her, but with Ferb combined with him from Heinz Doofenshmirtz's Combine-inator. ").

While on hot air balloons, Isabella's balloon is behind Phineas's. Isabella asks him what he's doing, seeing him fidgeting with something on his balloon. He explains that his wheel is broken, but he stops talking because he heard something behind him. He turns around to see Isabella, who asked if he needs help fixing it. Phineas replied, asking her to hold the wheel still. Isabella immediately jumps on the opportunity and holds the wheel still, obviously overjoyed that she can put her arms around Phineas. Phineas didn't seem to mind, and replied by saying she is holding it perfectly, partially hinting that he likes having her arms around him. Isabella smiled and they stay in the same balloon together for the rest of the ride ("Last Train to Bustville).

Ferb Fletcher
Isabella is good friends with Ferb, likely because he is the stepbrother of her crush, although she seems to get annoyed when Ferb goes wherever Phineas does. Along with Candace, she has outright stated that Ferb is Phineas' stepbrother ("Rollercoaster"). Unlike her relationship with Phineas, Isabella shows no romantic interest in Ferb. However, after time-traveling to the future, she learned that she might marry Phineas or Ferb ("Phineas and Ferb's Quantum Boogaloo"). Upon this discovery, Ferb turned around and winked at Isabella, who was very 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 when Phineas gets all of Isabella's attention and praise for being a superhero ("The Beak") or it can be just the thought of him being the one who controls the lower half and Phineas gets all the attention. When they were stranded on the island, Ferb listened while Isabella talked about Phineas not noticing her, and offered her a handkerchief when she started crying, and Isabella thanked him. He knows about Isabella's crush on Phineas. ("Phineas and Ferb Summer Belongs to You!").

Baljeet
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, suggesting some romantic interest towards Isabella (but it was a fake date) ("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").

Buford Van Stomm
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.

Candace Flynn
Isabella and Candace are good friends. They both know about each others' respective crushes and share advice and experiences at times ("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, Isabella felt jealous of Candace's relationship with Jeremy since Isabella didn't get hers ("Phineas and Ferb: Summer Belongs To You!"). When Isabella excitedly realized that Candace's future daughter called her "Aunt Isabella", meaning that she married into the Flynn-Fletcher family, Candace reminds her that she could marry either Phineas or Ferb as a counterbalance ("Phineas and Ferb's Quantum Boogaloo"). Candace teamed up with Isabella to beat Buford and Baljeet ("Got Game?"). Isabella 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 had not been for Isabella, she would have never gained 50 Accomplishment Patches in a single day ("We Call it Maze"). Interestingly, Candace doesn't try to bust Isabella in Not Phineas and Ferb, even though she acknowleged that Isabella was in the backyard. This may mean that they are very good firends.

Fireside Girls
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, like driving a van to get sap ("Isabella and the Temple of Sap"). Although the girls are loyal to Isabella, and have earned many badges in helping the boys, they have voiced that they've collected more than fifty of the 'helping thy neighbor' badge 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").

Jeremy Johnson
Jeremy seems to like Isabella's idea in "Got Game?" about Candace being on Isabella's team. He also called her Miss when he wanted a table for him and Candace in "Chez Platypus".

Stacy Hirano
Not much is known about their relationship, but Isabella knows what Stacy and Candace were going to do one day. ("Spa Day")

Heinz Doofenshmirtz
Even though they are rarely seen at the same time, Isaabella directed him and his evil date to a table in "Chez Platypus". In "Wizard of Odd", Doofen witch Warlock wanted the boots from a crushed Suzy Johnson that were on Candace, but Isabella (as the Good Witch) said he had no control in the area has was in.

Perry the Platypus
Isabella petted Perry in Rollercoaster, saying that Phineas and Ferb could teach her some tricks. She also sang Come Home, Perry with the boys, suggesting she likes him as well, even though she has Pinky as a pet.

Pinky the Chihuahua
Isabella likes Pinky and feeds him grilled cheese, but he, like most other dogs will run after cats ("Journey to the Center of Candace"). Isabella also seems to have given him some orders to him as he almost ate Candace, but Isabella told him to stop, which Pinky did.("Hide and Seek") She also took him to the Fireside Girls clubhouse one day, but he left since he was an O.W.C.A. agent. ("Isabella and the Temple of Sap")

Jenny
Jeeny doesn't appear as often as the other characters do, but Isabella seems to know knows her name ("Rollercoaster:The Muscial!").

Mitch
Isabella seems to be a enemy to him, since he is a poacher and she thinks that is wrong. ("The Chronicles of Meap")
