In this chapter, we're going to see more chaos with the Moodulator. And yes, a reviewer told me what the name of the device was. I thank them for that.

Also, I hear that the creators of Phineas and Ferb made a new series called Milo Murphy's Law. Apparently it doesn't Star children who build things and their sister who tried to get them in trouble, just a boy whose really down in his luck.

Maybe I'll make a fanfic featuring those characters. I think perhaps I'll try crossing that over with Gravity Falls. It's kind of like Phineas and Ferb, wouldn't you say? Then again, Gravity Fall doesn't have nearly as many episodes as Phineas and Ferb does. It's kind of a long runner.

And speaking of running, Perry, Atrosis, and Dr. Drakken are going to have to do that soon.

Chapter 36: Not In The Mood

At Phineas and Ferb's house, Perry the Platypus entered the house through a secret entrance in the fireplace. And yes, the fireplace was not lit. It would be a foolish idea to enter the fireplace otherwise. He was a platypus, not a dragon.

"Where is Perry? Did Mom take him to the vet?" asked Candace. He didn't seem to have fleas. Of course, if he did, they had some flea powder that they could use.

Perry went to see Major Monogram and sat in his chair.

Before he sat down, he decided to drink some coffee.

It certainly made him feel rather energized, which was helpful for whenever he wanted to go on a mission.

And yes, even though he was technically only six years old (albeit not in platypus years), Perry tended to act like an adult.

Major Monogram appeared onscreen.

As usual, he had a mission for Perry the Platypus involving his arch nemesis Dr. Doofenshmirtz.

"Good morning, Agent P. The evil Dr. Doofenshmirtz is building a formula that will mutate anything that it touches. And yes, we believe that he's taken samples from Lake Wannaweep for that particular evil plan." explained Major Monogram. There was a reason why they called the camp Camp Wannaweep. Who even founded that camp?

"You think that they'll ever clean up that lake?" inquired Carl. That was one lake that he wouldn't want to go swimming in. He might grow an extra limb. Gill had already tried that and look at what happened to him.

"They actually DID clean up that lake, but Dr. Doofenshmirtz repolluted it." stated the man. It had caused a lot of problems. For some strange reason there was a teenage boy that ACTUALLY wanted to be a mutant so that he could infect others. Luckily, he had been stopped before the pandemic could spread.

Perry the Platypus wondered what Dr. Doofenshmirtz could be possibly planning this time. He had come up with quite a few evil schemes over the summer. In fact, he seemed to come up with an evil scheme every time Phineas and Ferb decided what they were going to do today.

All he knew was that he was plotting something evil. He was a mad scientist after all.

Now that he thought of it, didn't he fight him not too long ago when he was trying to steal one of Cyrus's inventions?

Then again, he did fight Dr. Doofenshmirtz a lot. He had probably fought Dr. Doofenshmirtz 100 times by now. He was probably going to fight him once per day of summer vacation.

Saluting Major Monogram as usual, Perry the Platypus decided to go pay a visit to Doofenshmirtz's evil lair. How many evil inventions had he made over the summer anyway? He wasn't sure even Dr. Doofenshmirtz knew himself.

Sure enough, the evil scientist was there to see him.

However, he was going through some mood swings.

Perry raised an eyebrow. Something seemed off about his archenemy today. Did he not build one of his inators like he usually did?

He looked around, and did not see an inator.

He scratched his head.

"Perry the Platypus, I'm so happy to see you!" exclaimed Dr. Doofenshmirtz. A wide smile formed on his face.

Perry wondered why Dr. Doofenshmirtz was happy to see him. Wasn't he always thwarting his schemes to take over the Tri-State Area? Of course, he had moved on to Middleton but anyways...

Suddenly, Dr. Doofenshmirtz started to look rather sad. A tear came out of his eye.

"Oh wait! You're here to thwart my evil plans, aren't you? You always do this! It's so unfair!"

Dr. Doofenshmirtz began to cry, pressing his hands against his eyes.

"Wah! Boohoo!" cried Dr. Doofenshmirtz.

Puddles of his tears began to appear on the floor.

Perry wondered why Dr. Doofenshmirtz didn't realize what he was there for when he walked right in. Well, he had caught on...eventually.

Dr. Doofenshmirtz continued to cry Apparently, he was flashbacking to one of his tragic backstories. Maybe Dr. Doofenshmirtz wouldn't be so evil if he didn't have such terrible parents. Perhaps living with ocelots was an improvement for him.

On the lighter side, Perry's parents seemed to have loved him. However, he hadn't known his birth parents for too long. He had been sent to the OWCA shortly after his brith to be trained as a soldier.

Perry the Platypus started to feel sorry for Dr. Doofenshmirtz. He did foil his evil schemes all the time. To be fair, he was trying to conquer Middleton which was where his family lived.

Dr. Doofenshmirtz became angry.

He glared at Perry the Platypus.

"I won't let you do this! You've thwarted my schemes long enough!" bellowed Dr. Doofenshmirtz angrily. He began to shake his fist in anger at Perry the Platypus.

Perry got ready to fight.

"Let's get ready to rumble!" exclaimed Dr. Doofenshmirtz.

However, the moodulator activated once again.

Dr. Doofenshmirtz then became scared.

Sweat came down his face.

"Oh no! You're going to defeat me again! Please don't hurt me! I beg of you!" exclaimed the evil scientist. He remembered all the times that he had been beaten up by Perry the Platypus.

Typically it ended with, "Curse you, Perry the Platypus!"

Dr. Doofenshmirtz went on his knees and started to cry.

"Surely we can negotiate, am I right? You strike me as a reasonable sort of platypus. You want money? I did spend a lot of money on Doofenshmirtz Evil Incorporated but I'm sure I still have some left." said Dr. Doofenshmirtz.

Perry the Platypus felt rather confused.

Since when was Dr. Doofenshmirtz so moody? He didn't recall him changing moods this quickly.

Had he fallen victim to one of his own inators? He wouldn't put it past him. If so, he wondered if it would eventually wear off. It would be awkward fighting his nemesis if he kept suffering those mood swings.

He noticed that there seemed to be some sort of chip on his arm.

He wasn't sure what it was.

Maybe he could talk to Major Monogram about it? Perhaps he could give him some answers.

At Dr. Drakken's evil lair...

Dr. Drakken's evil minions were still fiddling with the Moodulator, unaware as to what the Moodulator does. Perhaps they should have asked Dr. Drakken before they started playing with it.

Things were the same as usual. Dr. Drakken's minions were helping Dr. Drakken with his evil inventions.

However, they seemed to be rather confused by the blueprints.

"Alright! I hit the high score!" cheered one of the evil minions.

Now that he had gotten a high score, he decided to set the Moodulator down.

It had been set to love mode, like before.

Shortly afterward, hearts appeared in Shego's eyes, much like Isabella whenever she decided to pay Phineas a visit. It was the wonders of being a cartoon character.

A wide smile formed on her face.

"This again?" questioned Dr. Drakken. He remembered the time that he and Shego went out on a date. It was really weird. Normally it didn't seem like she was interested in him.

"You are so cute, Dr. D!" exclaimed Shego, pinching Dr. Drakken's cheeks with a wide smile on her face.

Dr. Drakken sighed. Why did he get the feeling that he already knew what was going on? And since when was Shego attracted to him, anyway? Normally she seemed sarcastic whenever he was plotting one of his many evil schemes.

Curious, he decided to see if any of his minions had been playing with the Moodulator. If so, he already knew where to find it.

However, his minions had already left the base and had gone back home, taking the device with them.

"What is going on with her?" questioned Dr. Drakken, scratching his blue head.

For some strange reason, he got the feeling that this was also happening to two other people that he knew. He wasn't quite sure who.

He didn't suppose that Shego had a Moodulator chip somewhere...did she?

"What evil scheme are you concocting today, Dr. D?" asked Shego.

"I was wondering where to find Frankenstein's brain...I was hoping to find it before those two annoying kids did." answered Dr. Drakken. It'd be thrilling if he created life, though creating life didn't sound exactly evil now that he thought of it. At least people wouldn't question his skill as a scientist.

"You sure you don't want to find a dodo bird? I heard that Phineas and Ferb are looking for one.." inquired the green-skinned villainess.

"Dodo birds are extinct! How are they supposed to find one?" asked the blue-skinned scientist. He was starting to wonder if that was a good way to spend your summer.

"I don't know, I heard Dr. Doofenshmirtz is considering building an inator that could help with that." noted Shego.

"Hmm..." said Dr. Drakken.

Elsewhere...

At Professor Dementor's lair, his henchmen were currently relaxing in chairs.

"You feeling OK, Professor Dementor? You seem lovesick all of a sudden..." remarked Atrosis. She had thought Ned was cute at first...up until he turned out to be a horrible boss.

She was glad that she had stopped working at Bueno Nacho. Working with Professor Dementor was so much better. That way she didn't have to worry about having her pay get docked an hour.

"I just vant to say zat you've been a wonderful assistant!" exclaimed Professor Dementor in his familiar German accent.

"Well, I've been working hard..." said the young lady. She never understood why Shego was so lazy when her employer needed her help. She should assist her boss when he needed her the most.

She wasn't going to make that mistake, that's for sure.

"Of course you have! I admire your loyalty towards me! Zat's vhy I'm going to reward you!" shouted the professor.

"Ooh! Am I getting a raise?" exclaimed Atrosis. That would really help with her bills. She just loved having a roof above her head.

On the other hand, she was already getting paid a lot of money as it was. She was probably getting paid more than Shego was. She didn't want to get too greedy.

"Vell, zere's zat, obviously, but zere's something else." answered Professor Dementor.

"Oh? What did you have in mind?" questioned the supervillainess.

"Vhy don't ve hang out? Just ze two of us!" asked the professor.

"Hang out? Um, sure." nodded Atrosis. This was a first. Usually when she and Professor Dementor were together he was with his muscular henchmen. Dr. Drakken's henchmen couldn't help but feel jealous of them.

Atrosis noted that Professor Dementor sure was acting strange, but it was nice that he wanted her to hang out with him.

On the other hand, Dr. Drakken was probably worried that they were going to replace him and Shego as the main villains.

That wouldn't be fun for them.

Speaking of Dr. Drakken, what was he up to anyway? Was he going to try to steal from another scientist?

If they were trying to steal from them, they had the giant mech ready. Professor Dementor had built it the other day.

Immediately, the two of them stepped outside and went to the local park.

"This seems kind of peaceful...are you going to dump toxic waste into the park?" inquired Atrosis.

"Not today!" exclaimed Professor Dementor. He was in too much of a good mood to do so.

"Alright, if you say so." answered the supervillainess. Polluting the environment created evil mutants that tried to infect others anyway.

One again, Atrosis wondered what was going on. It wasn't like her employer to put off an evil scheme.

Was he feeling OK?

Meanwhile...

Ron Stoppable had noticed Atrosis and Professor Dementor in the park, and was wondering what was going on between the two.

Professor Dementor certainly was acting strange. Normally whenever he saw him he was laughing wickedly. But today he wasn't laughing like that at all.

On the other hand, Atrosis was acting normal, though apparently she was wondering what was going on with Professor Dementor herself.

He wondered what was going on.

Were they plotting something evil?

Perhaps he should keep an eye on the two.

Now that he thought of it...what were they doing outside their lair like this? They didn't seem to be stealing anything that would assist them in their evil plans.

Curious, a police officer noticed them.

"Professor Dementor and Atrosis? Relaxing at the park? I've got to be dreaming..." thought the police officer.

Those two were certainly acting out of character.

For once it seemed that he wouldn't have to arrest them for their cartoonish acts of super villainy. Then again, Professor Dementor already had a criminal record. Apparently, he once tried to steal the Great Pyramid.

Ron had noticed as well. He was taking his sister with him to the park using a stroller. She already could walk, but she alresdy enjoyed the ride.

He too noticed what was going on.

So he decided to contact Kim.

"Yes, Ron?" asked Kim.

"It's Atrosis and Professor Dementor. For some strange reason they aren't doing anything evil. I was under the impression that they would be trying to seek world domination by now." answered Ron.

"They aren't? That is odd behavior for them." noted Kim. Dr. Drakken was probably the only one that had ever come up with more evil schemes than Professor Dementor.

"I know." agreed the blonde.

"Did they really give up on their evil ways?" questioned the cheerleader. It seemed kind of sudden for them to do that, though given Shego's fall into villainy from being a superhero it was plausible that they could change.

"If they did, what will you do when you're not at school?" asked Ron.

"I'm not sure." answered Kim Possible. At least they wouldn't have to worry about Professor Dementor using the electro magnetic disruptor for evil.

Whatever it was, she wasn't too interested in babysitting her brothers.

Phineas and Ferb were WAY more preferable. Besides, they could probably look after themselves given their high intelligence.

Maybe she could fight another supervillain.

Perhaps another member of her rogues gallery were plotting something evil. How big was the rogues gallery again? There was Duff Killigan, Gill, DNAmy...the Senors...the list went on.

Meanwhile...

"Agent P, how is your mission? Did you defeat Dr. Doofenshmirtz?" asked Major Monogram.

"I always enjoyed watching you fight him!" exclaimed Carl.

Perry the Platypus tried to explain the situation to Carl and Major Monogram.

"Wait, he's not doing anything evil? If that was the case why was he building that inator?" asked the man.

Perry shrugged. Maybe he had forgotten all about it? One of his inators probably induced amnesia. He hoped that he didn't get zapped with it, because if he did, he might end up forgetting his combat skills.

That would leave him a sitting platypus against Dr. Doofenshmirtz. At least it wouldn't affect his pet life.

He sure hoped that he didn't get hit by that.

If he did, he would probably forget about his secret agent.

Although, they did already have a device like that back at the OWCA Headquarters.

It was useful for when they wanted to avoid having their secrets spilled.

"Well, I feel rather sheepish. Maybe for now you can return to your family like you always do." suggested Major Monogram.

Perry nodded and removed his hat.

Dr. Doofenshmirtz raised an eyebrow.

"Huh? Where did Perry the Platypus go? Have you seen him, wild platypus?" asked Dr. Doofenshmirtz.

He was starting to miss him already.

Perry pointed in the opposite direction of his house. If Dr. Doofenshmirtz found out where he lived, that could cause trouble. Luckily, he doubted that he would hurt his family. He was sort of a friendly enemy, especially in his current state.

"Alright then! Thank you, wild platypus!" exclaimed Dr. Doofenshmirtz.

Dr. Doofenshmirtz left, unaware that he was being misled.

Perry returned to his house. He wondered why people never seemed to recognize him without his hat on.

As he did so, he noticed that there was a chip on Dr. Doofenshmirtz's neck.

Maybe he should try removing that so that Dr. Doofenshmirtz would return back to normal.

On the other hand, he didn't seem exactly evil in that state.

Perhaps it would be better if he stayed that way.

However, he didn't know what was causing Dr. Doofenshmirtz's abnormal behavior.

Perhaps he should investigate while Phineas and Ferb were building one of their inventions.

He would like to see what they built personally, but he was a busy platypus. He had to go to work. Evil wasn't going to defeat himself, even if the villain wasn't too threatening like Dr. Doofenshmirtz.

Perry the Platypus went back home.

"Oh there you are, Perry." stated Phineas.

Phineas attempted to hug Perry, but he had walked away.

He felt like he had experienced enough love for one day.

"Huh. I wonder what's gotten into him." stated Phineas.

He was acting a bit strange.

Perry decided to contact Rufus.

"Hello!" exclaimed Rufus.

For some strange reason, even though Rufus was a naked mole rat, he was capable of speech.

Perry wondered if he could somehow learn how to talk.

There were some things that he would like to say to Major Monogram.

Meanwhile...

Ron was playing with his baby sister Hana Stoppable.

Hana giggled.

It was always nice hanging out with his little sister.

Currently, they were watching TV.

They were watching Puppet Pals.

"You think that Mr. Sitdown is going to sit on somebody?" asked Ron.

Hana noted that there didn't seem to be a lot of meanies on this show.

Since there was a surprising lack of evil in the world today, he decided that he would spend some time with his sister. It was too good of an opportunity to pass up.

However, he was still asking himself questions.

Why weren't Dr. Drakken and Professor Dementor doing anything evil?

Had world peace finally been achieved?

If so, they were probably very upset.

He wondered how Kim Possible would react to that. She wouldn't need to save the world anymore.

She was probably going to get bored.

Kim Possible gave Ron a phone call.

"Yes, Kim?" asked Ron.

"Hey Ron...I'm bored. It doesn't seem like I have anything to do." said Kim.

Both Dr. Drakken and Professor Dementor hadn't been doing anything evil recently.

"Let me guess, it's because your rogues gallery have been quiet." stated Ron.

"Well, two of my biggest foes seem to have given up on being evil." answered Kim. What were they up to? Did they live a life similar to hers? She was basically living two worlds.

"Well, Phineas and Ferb seem to be having fun." said the blonde.

"They always are." answered Kim.

Currently, they were building a race track.

"Didn't you already build a race car during the summer?" questioned Isabella.

"Yes. Yes, we did." answered Phineas.

However, it seemed this time they were racing with monster trucks.

Kim Possible decided to investigate.

This race seemed rather fun...but she got the feeling that it was going to attract the attention of a member of her rogues gallery. She remembered the time that Duff Killigan had made off with their golf course.

However, she wasn't quite sure which one.

She had faced quite a few foes over the years. Some of them continued to fight her, some of them didn't.

For now, she decided that she would join in the fun. She didn't have anything better to do anyway...she could hang out with Cousin Larry, but he didn't share the same interests.

Candace groaned.

"For some strange reason they always do this when Mom ISN'T home..." noted Candace.

How long was she going to be gone for, anyway?

She wanted to know.

Meanwhile, Perry the Platypus explained that there was a chip on Dr. Doofenshmirtz's arm.

"There is?" asked Major Monogram.

Perry nodded.

"We'll have to investigate that." said the man.

Perry nodded again.

"For now, enjoy the rest of your day." stated Perry's employer.

Perry saluted Major Monogram.

Please read and review! I appreciate it. Any other Kim Possible villains I should use in the fanfic? Just wondering. I could probably use Adrena Lynn even if she wasn't popular enough with the fans to make a return appearance, unlike Motor Ed. Of course, it probably helped that he and Dr. Drakken share the same voice actor.

I hope you're looking forward to the next chapter. I figured I would continue this fanfic since I was having fun with it.
