is part of cooperraymer's Sonic Team and one of the main characters in the Sonic Storm Adventure Series.
Perry is a docile pet platypus who lives with both Phineas and Ferb. They both adopted him because his unfocused gaze made it seem like he was looking at both Phineas and Ferb. What his owners didn't know is that he lived a double life as a crime-fighting secret agent working with for the O.W.C.A (Organization Without a Cool Acronym), going by his code name "Agent P."
Perry's First apperance in the series
He was able to keep his identity a secret, that is until he made his debut in Sonic Storm Adventures of Rush Hour 2. Phineas, Ferb and Perry along with the rest of Team Sonic traveled to China for a vacation with Detective Lee and James Carter. On the trip they run into Dr. Doofenshmirtz and his 2nd Dimension. 2nd Dimension called on his pet, Perry The Platyborg, to attack Phineas and Ferb. Perry realized he can no longer keep his identity a secret and blows his cover to save his owners. Phineas was extremely frustrated and heart-broken by this because he thought Perry never cared about them, that is until Perry was captured by Dr. Doofenshmirtz and his 2nd Dimension. Phineas forgave Perry and they teamed up to take down 2nd Dimension Dr. Doofenshmirtz. However, at the end of Sonic Storm Adventures of Rush Hour 2 Sonic told Phineas and Ferb that know that he's blown his cover will have to be transfered to a new family at a new state. Phineas, Ferb, Team Sonic and Perry's only choice was to be taken to a new state. But, Perry realized that Major Monogram, his superior, did not know what happened to Perry in the film. Perry's only options were to wither quit the O.W.C.A or never see his owner or Team Sonic ever again. Perry made his choice and decided to quit the O.W.C.A, thus being able to stay with Phineas, Ferb and Team Sonic.
- Perry The Platypus made his first appearance in Sonic Storm Adventures of Rush Hour 2. However, this film is being delayed.
- Perry now spends more time hanging out and fighting along side with Phineas, Ferb and Team Sonic ever since quitting the O.W.C.A.
- Perry never talks despite being anthropomorphic. The only way he communicates is through an "aggravated purr" type noise made by flapping his bill.
