Isabella Garcia-Shapiro

Isabella Garcia-Shapiro is a character from Phineas and Ferb and is a reoccurring character in The Disney Club. She is the leader of Fireside Girl Troop 46231 and sometimes helps the gang in their adventures, though more often than not she just sticks around Phineas and Ferb to help them with their "Big Ideas".

Personality
Isabella is typically cheerful, fearless, optimistic, and easy to get along with. She's always eager to help out wherever she can and is always excited to go on some crazy, new adventure. Thanks to her experience as Fireside Girl troop leader, she usually level-headed in most emergencies and can come up with creative methods to get the team out of sticky situations. However, as nice as she can be, she can also get very angry. She hates being talked down to, least of all being told what to do by bullies and bad guys. She also has a problem whenever someone else uses her catchphrase: "Whatcha doin'?", often confronting the violator physically.
