This is about Isabella from the 1st Dimension. For the one from the 2nd Dimension, visit Isabella Garcia-Shapiro (2nd Dimension).

Isabella Garcia-Shapiro is a character in Phineas and Ferb and in the In a Locked Room series of roleplays. She is the across-the-street 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.[1]


Isabella is cheerful, fearless, quick-thinking, sweet, optimistic,and easy to get along with. She is always eager to help with Phineas and Ferb's Big Ideas. When she participates with Phineas and Ferb in their endeavors, it's either for the fun of it, accomplishment patches, or a way to simply be with Phineas.

Isabella is sympathetic and aids people who are in need of help.

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.[2]


Isabella has long, black hair with thin blue hi-lights, curtain-like bangs and a round bottom, an oval shaped head with a flat top, and dark blue eyes. She wears a pink jumper dress with a similar white T-shirt underneath and a 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.[3]

Her Fireside Girls uniform is the same format as her normal clothing, with the exception that her jumper 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.[4]

In the Locked Rooms, she mostly wears her Fireside Girl uniform instead. She is rarely seen in her normal outfit.


Isabella has displayed numerous skills and abilities. She appears to be very physically capable, being a fast runner, and also remarkably strong, having been able to hurt Buford by elbowing him and crushing a pencil.

Isabella has demonstrated exceptional musical ability. She's an excellent singer and can play various musical instruments. In addition to this, she can dance very well.

Though admitting to being too young to legally drive, Isabella possesses remarkable knowledge over the anatomies of automobiles and is capable of flying small jet aircraft, such as a fighter jet.

Isabella has shown that she is very clear headed during emergencies.

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.
