Official Flynn-Fletcher residence is where Charlotte lives in the house on the hill in Danville.  

Both parents usually stay at Evil Incorporated. 

Phineas is always home alone. Candace moved away a long time ago, and Ferb ran away when he got the chance. 

Again, this is ambiguous. 

Phineas and Ferb are best friends and brothers (obviously).

CHEM and LOVE MUFFIN are two individual organizations that rival each other. 

It could be that Phineas had an uncle (or any other type of relation) who goes by the name Perry who is also a secret agent. The platypus thing could all just be in his head. 

The evil couple is most likely resembling “Harley Quinn and Joker” love, but less intense and more on the side length where Linda just wants to be with Lawrence, while Lawrence himself is shielding the reason he went evil. 

The main plot: Candace ran away to Vanessa’s house and lived there. They stayed as sisters from then on. Doofenshmirtz would go to therapy so he could continue having custody of his daughter. The day would continue as what would occur in canon. Phineas would try to reach the story. Linda and Lawrence would be up to no good, so CHEM would sometimes call in Doofenshmirtz or other agents to deal with them. Their evil plans would be foiled. Candace and Vanessa’s inventions would go unnoticed by both their parents. The day ends with a different twist. 

Something like that, I guess. 

Huge thoughts could be made up of the story’s relations. 

Ferb and Vanessa would have chance encounters.  

Phineas would always wear a hood over his head and look shyly on at Isabella as they go on dates. 

Pinky doesn’t like Phineas that much, so he sometimes tries to bite him. He knows that he’s Lawrence’s kid and doesn’t like being near him. 

Everybody believes that Phineas was raised to be just like his father.

Doofenshmirtz’s brotherhood with Roger is one he would rather ignore. 

The kids are teenagers, so they’re somewhere between the ages of 12 and 15. 

This is a Role Swap/Switch AU (I thought it was a reverse au). 

Relevant or not, I suspect a reason why Major Monogram does not want his son to join OWCA.

Here me out. If not, feel free to ignore my little headcanon.

What if the OWCA agents at one point were once humans?

Now, that doesn’t explain much. Only that the animals are using human brains that once belonged to regular people. People who volunteered for this somewhat insidious project. All the animals have no recollection of the lives they previously had because the primal organ inside of them will no longer supply memories, only the space that allows humans to become intellectual. Thus, superior animal races with some of the human capacity of understanding still fully-functioning.

This also makes me question if Doofenshmirtz, at one point, had vital pieces of his brain organ removed. That does explain some of his character traits. Specifically, a flashback to his youth, when we see he’s raised by ocelots. We don’t actually get a full explanation that would lead him to that point. What if those ocelots were able to tell that he’s their biological son because what if — hear me out — some of the brain of a young ocelot were also used to replace the organ in Doofenshmirtz’s head?

This sounds incredibly far fetched, trust me I know.

One of the interesting facts that i just made points out that Perry the Platypus is just like Doof in some ways. They’re the product of a experiment OWCA made, including some other shadow government I suspect.

In Milo Murphy’s Law, even Hansel and Gretel, we’re able to view so much plot that are never fully dived into. Like, what is up with Block (present time MML) is he a part of a bigger plot hole. Could his possible shadiness be linked to the possibility to a major breakthrough for the franchise? Are some of the aliens species referenced to each other? Like how in Hansel and Gretel, they “gifted” them superhuman powers? Is it really necessary?

Can this be the reason why Monogram doesn’t want his son to become part of OWCA because he could possibly lose him? Is this why their agents are only animals because they’re all hybrids of creation made by man?

Is the world only made at peace because something happens to OWCA and the aliens in the future?

Enjoy some Phineas and Ferb Replacement/Roles Reverse AU angst.

Lawrence Fletcher and Linda Flynn-Fletcher are both evil and have a do-gooder nemesis, Heinz Doofenshmirtz. 

Candace is the eldest and has a talent for building stuff. 

Ferb is actually a spy for a secret organization called CHEM (Charted Headquarters of Elite Mammals).

Phineas is the youngest one and has a secret gift that makes him seem mentally unwell. 

Perry is his imaginary friend and assumes that he’s not real. 

Doofenshmirtz has the same life as Lawrence. Except that he has to go to daily therapy so he could stay as Vanessa’s guardian. He’s sometimes called in by CHEM to deal with the elusive couple, Linda and Lawernce Fletcher. 

It’s ambiguous what you think happens to Charlotte. 

Vanessa and Candace have been friends since early childhood. They’ve stayed together until Candace basically moved in. 

Stacy has high expectations for herself and prioritizes most of her plans for her future too seriously

Jenny is fixed on being seen as rough when she actually has a kind heart.

Jeremy is a former Fireside boy scout and has had a crush on Candace since she moved in. 

Isabella and Phineas like each other.

Jeremy’s friend, Coltrane, has a crush on Stacy. Coltrane was also a part of Jeremy’s Fireside troop. 

Vanessa has a crush on Ferb, who also feels the same way.

Baljeet is more laid back and chooses to be his own person than someone others think he should be. 

Buford is more calming and chooses to use his strength to get more donations for fundraisers. In lifting, he’s not violent. 

Perry the Platypus is a secret agent that is meant to keep on eye on Lawrence’s long-forgotten spawn, Phineas Flynn. 

Lawrence feels disappointed that Phineas refuses to enter his full potential. 

I kind of thought Mary Dugan (Sherlock 1955 - 32) looked like female Aziraphale from Good Omens
