OK, this is my first fanfic trying on Phineas and Ferb, one of my favorite TV shows. Enjoy and feel free to suggest.

Since it's proved that this and Milo Murphy's law are in a same universe (really, same creators, same city, and even crossovers with Perry and Dr. D become recurring characters), so in PnF fanfics there'll be some MML references and characters, same with MML. While MML Season 1 probably shares the same timeline with PnF show's timeline, I guessed Season 2 is after PnF, even after "O.W.C.A. Flies".

This story will take after MML season 2 finale.


It had been some days after the space trip, for Dr. Heinz Doofenshmirtz, it seemed that it was just some hours, though.

Milo and his family were out to have some family time, and Cavendish and Dakota decided to help Cavenpuss to find some place where he could belong to, so Dr. D would have the house alone. Not wanting to waste the time, he decided to have some quality time by looking for the TV remote, until he heard someone knocking.

Dr. D opened the door to see, "Perry the Platypus? Well, it's really nice of you to join in. You know, I was preparing to have some TV time, but you are feel free to join. You're here alone, are you?" To his surprise, the teal platypus shook his head as he pointed to the outside, to which there are another two agents waiting, one is a panda, the other is a chihuahua.

"Peter the Panda?! No offense, but what are you doing here?" Doof gasped, then Perry "grrr"ed to explain, to which Doof understood his meaning, "so Professor Mystery is having a day off?"

"Grrrr..." Perry chattered. Doof understood it, turns out, the panda has nothing else to do so he decided to join with his platypus buddy, finding some way to kill the time and also being interested in how Perry's day became after his nemesis giving up being evil.

"OK, I get it. But what about the dog? Wait a minute, isn't that your pet dog?" Doof then asked again.

Perry chattered again as Doof heard his means and looked at the dog, "So he says your name is Pinky? Nice name, and nice to meet you anyway. Well, come in please, the TV won't wait, until I find the remote."

Peter and Pinky merely rolled their eyes and looked at Perry, who just merely shrugged as they entered the house.

(30 minutes later)

"BAM, there is no good shows! Seriously, what happened with the TVs nowadays?" Doof just grunted as he turned off the TV, "Guess we have to do something else to kill the time. So, Perry the Platypus, how is your host family doing recently? Well, you know, I have nothing else to ask from you." Turns out, it's revealed that Doof has known Perry is a family pet and he knows the "pizza delivery guy" is his owner once he got his memory about 2nd dimension back, he knew Perry had to leave his family once his cover was blown, so he had agreed Perry he won't hurt his family (seriously, he doesn't even plan of doing this, he's also a family man after all). Heck, Perry even told Doof more about his family by showing him all the photos, which he has never done to any other people, and only Pinky and Peter were completely aware of this when Perry informed them about this.

If his family can be aware of this without him leaving, then all of this is better.

Doof looked at the sad expression of the platypus' eyes. He knows why the platypus is sad, "So they were still having no idea of your identity? But wait, I thought your pet dog knows."

Pinky just glared at the former evil scientist and barked in frustration, Perry also chattered just in case Doof wouldn't understand. "Wait, you are not his pet dog but just a fellow agent? Well, make sense, I mean a platypus has a pet dog? Quite ridiculous, I gotta say, we're not in the other Disney cartoons, after all."

"Listen, Perry the Platypus. I may know not too much about your family, but I think it's all your decision to tell them or not." Doof explained, "Do you really love them?"

Perry was surprised at what his frenemy said, but he nodded nonetheless, he does care his family after all.

"And you're even willing to leave them if you have to keep them safe, right?" Doof asked, "But the key question is, DO you WANT to let them know? Because if you want, there must be some way you can get this, right? I mean seriously, why does OWCA HAVE to know about this?"

Perry was basically surprised at this, Doof was right of this, why do they need to know? He remembered Stacy knew his identity all the time, so why couldn't his family? As long as they kept it as the secret, then maybe he would be allowed to stay! Perry then turned to look at Peter and Pinky, both of them gave him a thumb-up and zipped their mouths. Pinky understood Perry's love for his owners and he also wished Isabella could his, too. Peter also understood this, since he knew if the platypus was heartbroken to lose his (former) nemesis, it could only be worse if his lose his family.

"So, you all agreed? Great!" Doof cheered, "Now I know what I am gonna do today, let me see if I had my old blueprints of my Remember-inator." But suddenly, a knocking on the door was heard.

"Huh? So Milo is back? Wait, I thought he has keys." Doof was confused but still went to open the door. At the same time, Perry motioned Pinky and Peter to hide at someplace, just in case. To their surprise, they found standing outside was a mystery figure in a dark purple cloak.

"Finally I found you, Dr. Heinz Doofenshmirtz or should I say Professor Time." The figure just greeted.

"I'm sorry, but you are looking for me? Listen, I didn't owe the others any bill." Doof just replied, "Also, how did you find me?"

"Well, I had my ways." The figure replied calmly, "Did I just hear that you planned to regain Perry's owners' memory about... that?"

"What are you doing?" Doof was immediately alarmed, fearing this visitor is a tattletale. Perry was also alerted as he, Pinky and Peter put a fighting stance and ready to tackle him. However, the figure let out a chuckle, "No, you just misunderstood. I won't against this, quite on the contrary, I support this. By the way, I was originally planned this for ya, but now since you are already planning this, why shouldn't you make this better?"

"What do you mean?" Doof asked in confusion.

"I'll make sure OWCA won't relocate Perry even if they find out." Doof could swear that the figure was smirking even though he couldn't see his face.

"Really? And how are you gonna prove that?" Doof asked in suspicion as he raised an eyebrow.

"Because an upcoming threat is coming to disturb your life, and they will make trouble on you, Perry, and your family and friends. That threat was originally what I need to deal with, but it is necessary to need your, Dr. D's, OWCA's, and your family's help. So I'm here to tell you that OWCA has to let your family know your identity, and I promise you that they won't even try to relocate you. Trust me, just like you trust Dr. D."

Perry was surprised at this when he heard sincerity from the words, a tear formed at his right eye as he wiped it with a smile.

"Then I hope you'd better follow your promise." Doof rebuked, "And one last question, who are you exactly, and what's this threat exactly? L.O.V.E.M.U.F.F.I.N return?"

"You will know it when time's right. Don't you have a Remember-inator to build?" The figure just replied flatly as he disappeared in a smoke. All the four just stared in confusion but decided to back to re-create the inator.

"OK, Pinky the Chihuahua, mind helping me get that wrench?"

The chihuahua just barked.

"You know, I need to create a Translate-inator, too. I can't always let Perry the Platypus do the translation."


At O.W.C.A. Headquarters...

Major Francis Monogram was preparing to leave as his unpaid intern Carl was checking out all the equipment. Suddenly, an alarm was set off as both of them gasped.

"Great Googly Moogly!" Monogram gasped, "Carl, what happened?!"

"Sir, apparently there's rough agents broke out and they are on the loose!" Carl gasped as he check the security camera.

"Quick, Carl, get Agent P on the line immediately!" Monogram replied, "And also the other agents if they hadn't gone, yet."

"Wait, sir! Something new happened!" Carl said as he checked the security cameras again, "There's two cloaked figures arrived at the scene and they defeated the rouge agents and sent them back!"

Monogram stared at the scene in surprise as he grabbed some popcorn to his mouth, "They're not OWCA agents, they wear cloaks instead of fedoras. What are they up to?"

"To test our abilities and want to have some deal with you." To Monogram's surprise, the two cloaked figures suddenly showed up in front of him and Carl, who screamed in panic and tried to run away before Monogram stopped him.

"Who are you?" The major asked calmly.

"Just want to say we're your future allies." One of the figures replied, to the voice it's clearly a she, "And sorry for releasing your rouge agents but we need to use some targets to test out."

"Wait, you released the rouge agents?!" Monogram asked, "But how?! We have security systems to make sure they won't get away!"

"We have our ways." Another figure, who's taller than the first one, shrugged, "But forget this because we took them down. And we wanna have a deal with ya."

"Before this, we need to tell you who we are and why we're here." The first one continued in a calm voice.

(One short and secretive explanation later)

Carl was pacing around and waiting in anxious. The figures had been in the office with Monogram for a long time and he couldn't even eavesdrop what they were talking. And suddenly...

"Yo, Carl!"

Carl turned his head to see a kid, he's light skinned with orange buzz-cut hair and wearing a pair of magenta glasses. He also wears a dark blue shirt, grey shorts, black socks and white sneakers. The kid was Irving Du Bois, a self-proclaimed Phineas and Ferb's fan.

"Hey, Irving." Carl greeted. To be honest, how this kid found out OWCA was still a mystery for him. In order not to let the kid spill the beans, Monogram had to let the kid work as an unpaid intern just like Carl since he had to do a summer job for homework. Despite this, Irving still enjoyed the work and he and Carl really get along great. Also, Irving found out Perry's identity, hearing all the stories from the platypus himself and knowing why he had to do this, Irving agreed not to tell this to Phineas and Ferb, even though he always wants to.

"What's going on?" Irving asked, "I heard the alarm was off so I come here to check it out."

"I don't know what it is exactly." Carl scratched his head, "All I knew is someone broke in and they wanted to make a deal with us. Now I hear them talking with Major Monogram but I can't hear anything." At the time when Monogram came out with the two figures followed behind, "Are you sure we have to do this?" He asked hesitantly.

"Sir, what do they want?" Irving asked.

"Carl, Irving." Morogram sighed, "they want us to...

.

.

.

To give Agent P's owners and friends' memory back."

"Wait what?" Both the interns gasped in surprise.

"But, sir. Isn't that good?" Irving asked in excitement.

"I know, but that will break the rules, you know if any agent break the rule, they will be relocated and the people will lost their memory." Monogram replied.

"But, sir. Why should us have to do this rule?" Irving suddenly replied, "I mean, I really hates this rule once Perry told me about it. He really cares about the Flynn-Fletchers so much and I heard him telling me he risked his life to save them for many times! And he felt hurt doing this."

"I know." Monogram replied, "But what worried me is if any villain find out, they would threaten Agent P by harming them!"

"I thought Dr. Doofenshmirtz is no longer evil, sir. You need to trust him, not to mention Perry was also hurt for looking an eye on him last time." Irving added, "Plus, ever if there were others, do they have to know this? Not to mention, I'm sure Perry will do anything to keep his family safe, even if it means leaving forever or quitting."

Monogram was not an idiot, and not heartless, either. He knows the top agent of his organization loves his family no matter what, and he understands it. He personally was also against this action but he still has to follow the rules, so after some mind debating, he finally made up his decision.

"Fine, I'll break the rule for once. But I need to do some things to make sure it's all OK." The Major replied.

"Suit yourself." One of the figures, the female one, nodded, as both of them disappeared in smoke, "You'll hear more of us when time's right."

"Carl, tell Agent P we need to think a way to get his owners and restore his memory." Major Monogram ordered, Carl immediately followed while Irving was cheering in excitement, feeling happy that his heroes will know more about his owners.


The two figures came out of the OWCA, and they found the other figure coming towards them. Comparing to them, this guy is slightly shorter.

"So, how's it going?" The short one asked.

"Pretty good, chief. We successfully convinced the major to do this." The female one smirked.

"Nice job, gang. I know I can always put my trust on you." The short one, obviously their leader, smiled.

"Duh, we're always with you, after all." The tall one also smiled, "So, should we go back to the base and prepare for the upcoming threat?"

"Not yet, I guess we need to accomplish a bonus mission." The leader replied, "We need to find some guys who could be ready for our backup plan. They might be small, but from the show I saw great potential in them. And I'm sure they can be helpful. Once we found them, take them back to the base with us. I think we can give them what they want."


A/N: And this is all finished, hope you will enjoy this. Here I made Peter as one of Perry's best agent friends because I really like the panda, and despite it seems to happen in an alternative universe, the parts of him, Perry and Dr.D in "Lost in Danville" also exists in the original one, so don't mind that. Also, the idea of Irving working in OWCA is my own idea from "Act Your Age" because he was shown to be an intern for it in the episode, so somehow I guessed he knows Perry's secret and I wanted to give an explanation of why he chose to work for this.

Also the part where Dr.D referred Pinky as Perry's pet is a reference to the episode "Where's Pinky"

I'll back to do the new chapter for soon.
