Perry is the pet platypus of stepbrothers Phineas Flynn (voiced by Vincent Martella) and Ferb Fletcher (voiced by Thomas Sangster). He may seem boring but he has his own secrets and lives a double life. Unbeknownst to the brothers, Perry is a spy and has his own missions to carry out. His superiors call him called Agent P. His lair is located under the Fletchers' residence and one must go through a lot of secret passages in order to enter it. There are three in the backyard, the elevator in the chimney and lots of underground canals and mazes.
Perry is the enemy of Dr. Heinz Doofenshmirtz, a character voiced by Dan Povenmire. His main mission is to stop the mad scientist’s evil plans. Perry is always successful in doing so. He may appear to be a special needs platypus but he is actually a superhero who always saves the world.
Phineas always worries about Perry’s whereabouts when he’s not around but when Perry shows up, Phineas is just happy that he’s back and never asks what he did or where he has been.
Perry always serendipitously cleans up Phineas and Ferb’s messes. This is a blessing for the two because the evidence of their daily activities are covered up and are not seen by Linda Flynn, Phineas’ mom.
The Perry the Platypus theme song describes him as a semi-aquatic, egg-laying mammal of action. He is green in color, has a beaver tail and a bill.
Perry the Platypus is a character on Disney Channel’s animated series Phineas and Ferb. He is voiced by Dee Bradley Baker, the same person who has worked on Happy Feet, Totally Spies!, Lilo & Stitch: The Series, Scooby Doo 2: Monsters Unleashed and Stuart Little among many others.
