"Whatcha doin'!"
— Isabella, speaking in a tough voice

Isabella Garcia-Shapiro is the 2nd Dimension counterpart of Isabella Garcia-Shapiro. She is the second-in-command of The Resistance and the leader of the Firestorm Girls branch, specifically Troop 46231. Just like her boss Candace Flynn, she is bent on ending the reign of the Doofenshmirtz family.

Early life

Isabella's past life prior to the 1st Dimension citizens' arrival is unrevealed, other than she somehow became a member of The Resistance, worked her way up the ranks, and eventually became the second-in-command as well as the leader of the Firestorm Girls branch, specifically troop 46231. She is also assumed to have been born from Mexican and Jewish roots, like her 1st Dimension counterpart. During the early days of the Doofenshmirtz family's reign over the Tri-State Area, Isabella has lost her pet chihuahua Pinky, and is worried that he's been gone for a long time.

Present life

Isabella meets Phineas-1 and Ferb-1, along with their 2nd Dimension counterparts, when they stumble upon the Resistance headquarters after falling down a chute (most likely Pinky the Chihuahua's former lair) along with Buford, resulting in their capture by the Firestorm Girls. Buford's presence gets her to release the four. She is present when Dr. Baljeet opens a portal to the 1st Dimension, which is later disrupted and closed by Candace-1. Isabella later accompanies Candace, Phineas-1, Ferb-1, Candace-1, and Buford to Doofenshmirtz Evil Incorporated aboard mine carts in their quest to save a captured Perry-1, to which the group finds out that Phineas and Ferb stowed away.

Accompanying Phineas-1, Ferb-1, Candace-1, and Buford to DEI, they are nearly captured by Doofenshmirtz and Doofenshmirtz-1, but Perry-1 manages to escape and the group reunites with Candace, Phineas, and Ferb. A resultant chase by the Norm bots forces Candace to separate the mine cart containing the 1st Dimension group from the others, to which Isabella looked genuinely concerned about.

She is later among the Resistance members that congratulate the 1st Dimension group for defeating Doofenshmirtz (Phineas and Ferb The Movie: Across the 2nd Dimension).

Two month following Doofenshmirtz's arrest, Isabella is shown being in a more happier tone, similar to her original counterpart. However, she and the other kids had to deal with a gang of O.W.C.A. agents, who were captured and transformed into ruthless cyborgs by Doofenshmirtz's wife Charlene, whom also captured Perry. Also in a more a darker tone, Isabella learns that Pinky (now known as Chihuahuaborg) is among the cyborgs, much to her horror. In the end, Isabella manages to free Pinky of his evil programming and reunites with him, and she and the other Firestorm Girls attended the reunion of all returned O.W.C.A agents following the Doofenshmirtz family's escape. ("Tales from the Resistance: Back to the 2nd Dimension")


During her debut, this version of Isabella is tough, no-nonsense, and down-to-earth girl (some of these are what 1st Dimension Isabella lacks with); she even says her catchphrase in a tough voice during her debut. She also appears to have a sense in fashion, as stated by Candace. However, this personality trait is only shown when Isabella was on duty as both second-in command of Resistance and as leader of the Firestorm Girls, as her actual personality is similar to her original counterpart.

Isabella's reserved, no-nonsense, and strict personality were obviously the result of being hardened by constant struggle against the Doofenshmirtz family's evil reign. When Heinz Doofenshmirtz was eventually defeated, with help of Phineas-1 and Ferb-1's aid, she reverted to her original self that is similar with her 1st Dimension counterpart.

Physical Appearance

Isabella is physically identical to her 1st Dimension counterpart, although her eyes are slightly more oval-shaped due to her serious personality. After Doofenshmirtz is defeated she loses this feature however, to show that she has become more laid back than she originally was. She has only been seen in a silver shirt with torn sleeves; brown pants with diamond-shaped silver patches on the portion that covers her kneecaps; black shoes; gray gloves; a dark-green beret with a drooping dark-green bow on top; a brown strap slung over her left shoulder, holding what appears to be rolled-up strips of paper; and a tan badge with a green circle at the center, with a red lightning-bolt insignia running across it (most likely the Firestorm Girls symbol).


Resistance Members

Firestorm Girls

Just like the 1st Dimension Isabella's relationship with the Fireside Girls, the Firestorm Girls always follow Isabella's orders and are always ready and willing to aid their leader, even risking themselves in order to allow the process to be carried out.

Candace Flynn

Candace may hold a special trust in Isabella ("Phineas and Ferb The Movie Magazine").

Buford Van Stomm

When she spots Buford with Phineas, Ferb, and their 2nd Dimension selves, she expresses disgust towards him and said to him, "...What do you want? I thought you were resisting us?" This makes it evident that she was affected in some way by Buford's departure from The Resistance.

1st Dimension Citizens

Ferb Fletcher

It is shown that she holds affection for Ferb ("Phineas and Ferb The Movie Game: The Dimension of Doooom!").

Phineas Flynn

She may have feelings for him like her 1st dimension counterpart, she blushed when Phineas complimented her idea about a Ninja glove (Phineas and Ferb: Across the 2nd Dimension video game).
