Perry the Platypus, also known as Agent P, or just Perry, is the tritagonist of the series Phineas and Ferb. He is Phineas and Ferb's pet platypus, who lives a double life as a secret agent for the O.W.C.A, a secret government organization of animal spies tasked with filing mad and evil scientists. He used to fight Dr. Doofenshmirtz, but at some point after the series ended, he joined the O.W.C.A and started fighting alongside Perry. He was able to keep this a secret until Doofenshmirtz gave it away in "Off to the Falls". However, Perry has been able to keep his blown cover a secret from his immediate superior Major Monogram for the 2 years that followed. He serves as the deuteragonist of the Rise of Bill Arc from Forever Sophomores and the Cipher's Law Arc from Advanced Education, as well as the protagonist of the Return to the 2nd Dimension Arc from Senior Year.
Perry is a small cubic platypus with teal fur, a yellow beak and webbed hind feet. He has a thick beaver-like tail of an orange shade. He has blue eyes, and two hair strands sticking out of his head. When acting as a docile pet, Perry has a blank expression with his eyes facing opposite directions to achieve the "dumb" look, and moves on all fours. When portrayed as a secret agent, Perry becomes bipedal and wears a brown fedora on his head. In contrast to his mindless and wild-eyed expression as a pet, the secret agent version of Perry has a stern look with his eyes oriented properly.
While undercover, Perry can normally be found with his owners, Ferb and Phineas. As their pet, he lives up to the expectations for a platypus and "doesn't do much." Even though Candace would describe him as just a mindless, smelly animal, Perry still shows signs of intelligence when he's pretending to be a normal pet, so she may mean insane rather than dumb. He is also serious while on duty as an agent, even in front of Major Monogram when he does anything silly ("Jerk De Soleil", "Boyfriend From 27,000 B.C.", "Traffic Cam Caper", "Skiddley Whiffers").
Perry appears to be selfless and devoid of vanity. In "The Best Lazy Day Ever", it is only after he turns everything else affected by the Ugly-inator back to normal that he reverts himself to his normal state. He deeply cares about the Flynn-Fletcher family and is afraid to lose them. He will take immediate action whenever they are threatened ("Journey to the Center of Candace", "Phineas and Ferb Get Busted!", "Oh, There You Are, Perry", Phineas and Ferb The Movie: Across the 2nd Dimension, "Where's Perry?", "Where's Perry? (Part Two)", "Phineas and Ferb Save Summer"). He is nice to not only his allies but to his nemesis Dr. Doofenshmirtz as well, though only on some occasions ("Oil on Candace", "Thaddeus and Thor", "Brain Drain", "Skiddley Whiffers", "When Worlds Collide", "Road to Danville").
When hanging out with his owners, Perry is shown to act very serious, making sarcastic comments whenever his owners say or do something stupid. He also doesn’t freak out as much whenever he gets insulted by Candace. Instead, he tries to stay calm about it(“Subway Night”). Unlike characters such as Rigby or Brian, Perry rarely laughs at any inappropriate joke or funny viral video thrown at him. Perry only laughs when he gets tickled. He is also shown to strongly despise the Nickelodeon show “The Loud House”, and would often angrily freak out whenever it comes on(“An Apologetic Vengeance”). Perry also shows no respect towards the Red-Sox. According to Tom’s sister, Allison, Perry often acts very rude towards the team by saying that they suck, and that anyone who supports them sucks(“Let’s Go, Bet-Sox”, “Return to Fenway”).
He also doesn’t get scared very easily. However, some exceptions include a jumpscare in a scary game Phineas and Ferb once played(Memories of a Platypus), and being in control of Bill Cipher. Perry would also get irritated whenever he was ignored(I Dream of Baldi). It should also be noted that Perry is deeply in love with Linda Flynn, who is the mother of Phineas and Candace(All in a Hard Day’s Work). However, this was later revealed to be a ruse to cover up his romantic feelings towards Dr. Doofenshmirtz(“A Brand New Reality”). Despite his serious nature, Perry would often get emotional at times, for he had been seen crying on a few occasions. This is usually caused by a conflict with close friends(“When Worlds Collide”, “Enter Agent P and Company! Finally on the Road to Maine!”), or from loss of hope when his life's on the line(“Rescue is Pointless”, “Wolf in Sheep’s Clothing”). Doof’s departure from OWCA in 2018 has caused Perry to become more visibly depressed and mentally broken than before, often having mental breakdowns and lashing out on others(“Back Together, Torn Apart”).
