"We're not enemies, we're-we're just bad friends."
"Oh, Perry the Platypus. Uh,how long have you been... An-and look at that! It's... It's Peter the Panda, my ex-nemesis. What a coincidence, huh?"
Peter the Panda is a secret agent panda from Seattle, he has the same hat as Perry the Platypus but of a lighter color. He used to be the temporary nemesis of Dr. Heinz Doofenshmirtz, and later on, he serves as the nemesis to the local Seattle mad scientist, Professor Mystery.
Meeting Dr. Heinz Doofenshmirtz
Peter the Panda lived in the city of Seattle, Washington, where he was a secret agent. One day, while at a convention center in the city, he met the evil Heinz Doofenshmirtz. Doofenshmirtz was a Drusselstein mad scientist who lived in the city of Danville and ran an evil corporation entitled Doofenshmirtz Evil Incorporated. The two "instantly disliked each other" and quickly became new nemeses. Peter was not aware that Doofenshmirtz secretly intended to have him make Perry the Platypus jealous which would lead to a series of events, allowing him to capture and freeze all the secret agents ("It's About Time!").
New nemesis in Danville
As Peter was now Doofenshmirtz's new nemesis, he went to the city of Danville in the Tri-State Area. At one point, Heinz had created a freezing machine, which was secretly a decoy for a real one, so Peter confronted and fought him in his apartment. While in the middle of their fight, Perry the Platypus arrived so Heinz quickly shoved Peter in his closet so Perry wouldn't know. Peter got out of the closet, however, so Doofenshmirtz explained to Perry what had happened and he left, depressed.
Peter and Doofenshmirtz continued their battle. Peter throws Heinz against the wall then kicks through a picture to hit him in his face. Looking at the picture makes Heinz nostalgic and begins to reminisce through song, thinking about his time as Perry's nemesis and about his feelings. Peter took this as an opportunity to disable the freeze ray, which made Doofenshmirtz upset and he walked away, allowing Peter to disable it further ("It's About Time!").
Doofenshmirtz's plan revealed
After the fight, Doofenshmirtz decided to go on the Dr. Feelbetter show, where it's host would try to reconnect Heinz and Perry. To help, Peter was put backstage, which Perry was, and Doofenshmirtz pretended to be, unbeknown to. When Feelbetter revealed Peter was backstage, Perry was upset and Doofenshmirtz tried to explain he had no clue Peter was there.
Feelbetter asks Peter to stack the chairs quickly and the show starts once more. Perry and Heinz eventually rekindle and decide to become nemesis once more. It was this point that Doofenshmirtz trapped all the agents in the audience with straps on their chairs, including Peter and Perry, and revealed his true intentions of freezing the secret agents. He also showed them his real freeze ray, which he would use to freeze the secret agents in the room for his giant chessboard.
Heinz apologizes to Peter as he feels things turned out "awkward." Teaming up with Perry, the two were able to break free of their captivity and freed the other agents. While the audience agents fought their respective nemeses, Peter and Perry tag teamed and took down Doofenshmirtz, along with his freeze ray. With Doofenshmirtz and the villains defeated, Peter discontinued his role as Heinz's nemesis ("It's About Time!").
Peter was later seen at the Inator contest where he was one of the captured agents, implying that he has moved on and found a new nemesis. After Perry freed the other agents, Peter assisted them in fighting the Inator contest's participants. ("Robot Rodeo")
During 2nd Dimension Doofenshmirtz's invasion, Peter aided the other agents in fighting the army of invading Norm Bots. They are quickly defeated after ambushing a group of Norm bots, but are saved by Perry. He then uses one of Phineas and Ferb's kiddie rides to fight off the invasion. (Phineas and Ferb the Movie: Across the 2nd Dimension)
When Doofenshmirtz arrives to Seattle, Peter attempted to get him a cup of coffee, only to be interrupted by the arriving Perry. He later teamed up with Perry once again to rescue Doofenshmirtz from the alien poacher Mitch, and later had dinner with Perry at a restaurant inside the Space Needle. ("Meapless in Seattle")
Peter once attend the O.W.C.A. Cadet Graduation Ceremony until it was interrupted by the members of L.O.V.E.M.U.F.F.I.N. (who are holding a similar event in the same ballroom, L.O.V.E.M.U.F.F.I.N.'s First Annual Disservice Awards). This resulted both organizations to engage into a fight, and Peter aids his fellow agents into fighting the villains. Later on, Peter and the agents get captured by the villains in their attempt to rule the world thanks to Doofenshmirtz's latest -inator. However, a street rat (whom Monogram befriended and recruited came to the rescue and freed Peter first before the other agents. They would later battle the villains again, only this time, the villains flee away after learning that it's just the same brawl back in the ballroom. ("Phineas and Ferb Save Summer")
Peter later plays a central role when his assigned nemesis, Professor Mystery, kidnapped Doofenshmirtz and took him to his lair to get rid of him because of his previous acquaintances with Peter. It turns out that Peter hasn't been doing out so well with Professor Mystery because of the latter's lack of communication, as Doofenshmirtz pointed out. Eventually, Peter arrives to rescue Doofenshmirtz again by confronting and beating Mystery, forcing him to explain his plan of finishing off Doofenshmirtz. Having no choice, Mystery is forced to explain his plan that his -inator erases anything from existence (much to Doofenshmirtz's shock). Fortunately, Perry arrives to rescue Doofenshmirtz from being erased, and Mystery finally decides to talk in with Peter in a coffee shop to explain about how he lost his family that led to his aim in doing evil. ("Lost in Danville")
Personality and traits
Peter hasn't shown any sign of communication. It is a possibility only other animals can understand him, but that is also unlikely. Peter, though cute and quiet, may have an aggressive and crazy side; as he was shown throwing chairs with a blank expression on his face (much like Ferb Fletcher, who usually keeps a straight face while doing various activities).
Peter doesn't seem to care about Perry's reaction to him. He could be happy about being his replacement, sparking the rivalry of the two. Or, since he (again) showed no true expression, he had truly no clue what was going on. Another explanation could be that he just lacks empathy.
Peter seems more serious with his agency work than Perry. He disassembled Doofenshmirtz's ray while Doofenshmirtz was "singing about his feelings", the opposite of what Perry does, waiting until Doofenshmirtz was done with whatever he was doing ("It's About Time!").
- It is unknown if Peter actually moved to Danville or if he simply traveled there. Due to the unknown and undetermined location of the city, it can not be judged the traveling distance needed for general trips to the city. It is also unknown what devices he had available to better ease the traveling if this is the case. On the other hand, in "Meapless in Seattle" and "Lost in Danville", it is seen that he lives in Seattle.
- Peter was mentioned when Doofenshmirtz quotes "Hurry up and stop me or I'll have to give Peter the Panda a call. Cause, you know, he'll stop me" ("Transport-inators of Doooom!").
- Heinz Doofenshmirtz is seen wearing panda slippers, possibly referencing this bygone nemesis ("Comet Kermillian", "When Worlds Collide").
- Although Perry was taken into space by means of Phineas and Ferb's rocket ship and one of Doofenshmirtz's traps, Peter is the only agent known to possess an actual spaceship.
- Though this may be due to him being in a different division than Perry.
- Peter is described as cool, cunning, and curiously cuddly. (Agent P's Guide to Fighting Evil)
- Peter the Panda has no visible mouth, although he is given a mouth in "Phineas and Ferb Save Summer" and "Lost in Danville".
- Peters hat was light brown in It's About Time! but in Meapless in Seattle and his other appearances, his hat was dark brown like Perry's.
