Learn the tragic and hilarious childhood of Dr. Heinz Doofenshmirtz from Phineas and Ferb. Discover the events that shaped the lovable, quirky villain of the Tri-State Area.

The beloved cartoon duo Phineas and Ferb are returning for new episodes this summer after a decade away and pretty much ...

Alongside their pet platypus, Perry, who secretly works as a secret agent, the siblings face off against the hilarious Dr. Heinz Doofenshmirtz, the evil scientist with absurd inventions.

Unbeknownst to the pair, Perry, their mute pet platypus, is a secret government agent code-named P who regularly dons a hat and trench coat to save the world from Doofenshmirtz, voiced by Povenmire.

Yet returning after a decade was daunting at first for creators Dan Povenmire and Jeff “Swampy” Marsh, who also voice Doofenshmirtz and Major Francis Monogram, to whom Perry reports.
