who plays the voice of isabella on phineas and ferb
List of Phineas and Ferb characters Isabella Garcia-Shapiro (voiced by Alyson Stoner) is a Jewish Mexican girl.[24] She is one of the brothers' best friends and has an obvious crush on Phineas Flynn of which he is unaware, though he has shown he cares for her from time to time. She is known for the catchphrase, "Whatcha doin'?" and is the leader of the Fireside Girls troop 46231. The troop often helps Phineas and Ferb in their projects.[25] She is named after series creator Dan Povenmire's oldest daughter.[26]
List of Phineas and Ferb characters Lawrence Fletcher (voiced by Richard O'Brien) is the father of Ferb and stepfather of Phineas and Candace. Lawrence sells antiques, is from the United Kingdom and is portrayed like a sitcom dad as being scatterbrained and unaware of what is going on. He often agrees to follow Phineas's instructions and even forces Candace to cooperate as if he considers Phineas and Ferb's skills normal. Unlike the boys' mother, he has seen some of the boys' inventions; he has not reacted negatively, and apparently believes that their mother approves. His precise surname is a matter of some dispute; in at least one episode, Isabella addresses him as "Mr. Flynn".[20] Jeff "Swampy" Marsh has said that Lawrence Fletcher is very similar to his stepfather, Bill.[21]
