Perry The Platypus
Perry the Platypus (aka Agent P. No, not that Agent P from Brawl Stars) is a platypus, however that he was a secret agent (a.k.a. Agent P) of O.W.C.A. and Phineas and Ferb's pet. He battled his nemesis Dr. Heinz Doofenshmirtz and also save Danville. He does not look retarded
Perry the Platypus is one of Disney Channel's horrible attempts at making a badass character. His only purpose in the series is to go to Dr. Heinz Doofenshmirtz's hideout and destroy Doof's Prepare-Your-Anus-Inators every day because there is absolutely no need to get the FBI or CIA to take care of him. He is banned from Koridai and even the Evil Teletubby Land (with the possible exception of Camp Lakebottom and Nice Teletubbyland). He's an enemy of Prof. Parenthesis, Viacom, Bowser, the Evil Teletubbies, and even Luan Loud
