Albert Du Bois

Albert is known as Irving's older brother. Albert does not think that Phineas and Ferb are special until Irving convinces him by getting Buford and Baljeet to dress up as Phineas and Ferb next to a hologram of Phineas and Ferb's replica of the Eiffel Tower. He attends a boarding school, and claims to have the nickname of "The Truth Detector". ("Not Phineas and Ferb")
