Things may be different in this chapter to the main show. Ugh, you know what? If something is different in any chapter to the main show, just assume it's on purpose. Okay? I'm tired of writing that for each chapter.

"Good luck, Agent P," said Carl, the intern.

As Perry headed over to Doofenshmirtz Evil Incorporated, he couldn't help feeling a pang of worry for his boss, who had been frozen like a statue. But if there was one thing he had learnt from five years of battling Doofenshmirtz, it was that the effects of the evil scientist's –inators could always be undone. Perry was sure that Major Monogram would be fine. Anyway, Perry was going to go battle Doofenshmirtz now, and that always cheered him up.

However, when he popped up in the pool of Doofenshmirtz Evil Incorporated, he saw the shadow of his nemesis, who looked like he was fighting someone else. Perry slammed the door open to see Doofenshmirtz holding a smoking laser. His nemesis gasped. "Perry the Platypus! I-uh…I-uh…uh…" He quickly hid the laser behind his back. "There's no one else here! I-I mean, w-what are you doing here, Perry the Platypus?"

Perry narrowed his eyes. If there really wasn't anyone else there, then Doofenshmirtz should have remembered that what Perry was doing here was coming for their daily battle.

Perry heard a rattling sound coming from the closet. Perry glared questioningly at Doofenshmirtz, who chuckled nervously and said, "I-I have mice?"

Perry stormed across the room towards the closet, which made Doofenshmirtz panic. "I-I wouldn't go in there if I were you!"

Perry yanked open the door and saw the smug face of his worst enemy at OWCA.

Peter the Panda.

Perry took a staggering step back, feeling like he was about to throw up. It didn't help that Doofenshmirtz had begun babbling, "Perry the Platypus, I swear, I've never seen this secret agent-looking panda before!"

Perry shakily pointed to the panda paw print on Doofenshmirtz's face. The evil scientist paused awkwardly.

"Well, there's a panda in my closet and a panda paw print on my cheek…but it's not what you think! W-we're not enemies, we're just b-bad friends!"

Perry put the most wounded expression on his face. Doofenshmirtz sighed.

"Sorry, Perry the Platypus. I didn't want you to find out this way." He took a breath. "Okay, here it is. Peter the Panda is my new nemesis."

Perry felt like he had just been stabbed in the gut. He turned shakily to look at Peter, who nodded smugly. Even if Perry had been wearing his proper translator, he would not have been able to speak. A lump rose in his throat and he looked back at Doofenshmirtz, waiting for an explanation.

He was given one. "We met at an evil genius expo in Seattle, and, well, me and Peter, we instantly disliked each other. And then, he foiled a little evil scheme of mine. And, I didn't plan it that way, it just happened."

Peter's smirk had disappeared, and now he just looked awkward. Doofenshmirtz must have sensed this because he said, "Peter the Panda, be a dear and go get us a soda."

As the panda walked off, Doofenshmirtz continued speaking to Perry. "It's not that I don't hate you anymore, I do! But look, I-I just think it's time for us to, you know, take a break and start fighting other people."

Peter came back with a soda, which he gave to Doofenshmirtz, who sipped it. "Thank you, Peter the Panda. I'd offer you one, Perry the Platypus, but I-I think it's better if we just have a clean break. Don't you?"

Perry didn't want a clean break. He didn't want an anything break. All he wanted was to continue coming to DEI and fighting Doofenshmirtz, his nemesis, his only nemesis, but that didn't seem to be an option anymore.

"So, where was I? Oh, yes." He adopted an evil pose. "Peter the Panda, you think you have outwitted me!"

Perry blinked. Both Doofenshmirtz and Peter stared at him. Then the former began shooing Perry towards the door.

"Perry the Platypus, you're—you're making this harder than it needs to be. Go on, it's over now."

Perry pointed at the –inator in the corner.

"Oh, that? That's a Freeze-Inator ray but, uh, I-I don't want to explain it again. I just gave the whole spiel to Peter. But, don't worry. He's stopping me." He pushed Perry out the door. "He's-he's got it well in hand. Goodbye."

He shut the door. Perry stared at it for a moment before turning and sadly walking away.

"Curse you, Peter the Panda!"

As soon as he heard those words, Perry realised it was over. His nemesis had abandoned him and got a new nemesis without even telling him until it was done. He felt like crying but he didn't until he was out on the street, where, typically, it was raining. Perry could almost hear the depressing song playing as he took his last look at Doofenshmirtz Evil Incorporated. He turned and caught sight of the small building behind him.

The Better Panda restaurant.

Even Danville was mocking him.

He sat down on the sidewalk, feeling the rain soaking him, and just cried. He really did care about Heinz Doofenshmirtz, and seeing him fighting someone else really hurt.

Not just anyone: Peter the Panda. Perry had thought that Peter had had his own nemesis, but apparently not. Apparently Peter was free enough to steal Perry's nemesis. Not only that, but Major Monogram must have known about it too. No agent was allowed to reassign themselves; they had to go through Major Monogram first.

Perry felt a slight pang of anger over his sadness. If Major Monogram thought it okay to replace Perry without even telling him, let along asking him, first, then Perry thought it okay to turn in his hat without telling or asking Major Monogram first.

When he got down to his lair, the monitor was still on. The swishing of the door alerted Carl to the fact that Perry was back in his lair. The intern watched as the platypus went to a wall cavity and placed his hat on the bust. He sadly watched the glass case come down.

But at the last minute, Perry snatched his hat back. He put it away where he always put it, and decided to go for a walk to clear his head before he decided whether to resign or not.

And it was lucky he did, for when he went out, he was found by a representative for Dr Feelbetter's show, where he reconciled with Doofenshmirtz and typically foiled his evil scheme. And as Doofenshmirtz yelled, "CURSE YOU, PERRY THE PLATPYUS!" for the thousandth time, Perry felt happy that things were back to normal.

But what would not be normal for a long time was his hatred of Peter the Panda, who had stolen his nemesis from him.

Who feels super sorry for Perry? Luckily, it all works out in the end :)
