Reimagining “Phineas and Ferb” role switch au

“Phineas and Ferb Across the 2nd Dimension” theory:

“2nd dimension Roger” was not seen in the movie because:

1. He escaped to an underground bunker when it all went down.

2. He was captured and fed to the Goozim. 

3. Doofenshmirtz had killed him after he lost his Choo-choo.

4. Doofenshmirtz killed his mother when he found out she was pregnant. 

5. Doofenshmirtz had burned down his home, killing both his parents. 

6. Roger never exists because both his parents are afraid of Doofenshmirtz. 

Good Omens Human AU***

When Ezra and Crowley first met, they were at this local slumber party that attended a fraction of their generation. On the same night, two foreign exchanged students were blamed for an incident that they didn't do and got in serious trouble for it. Their parents moved them away to different schools a week later.

Their class has been divided ever since, splitting between the single line that marks the side they're on. They used to be closer with each other, like brothers and sisters, little children who were taught in the same age group, but were seperated from an example that they try to settle in their own ways.

Now, Crowley had no problems with this as long as Aziraphale didn't, which he thought was an entirely different legion that he's somehow a part of. They're quite used to their own "side's" unusual superiority, which had Gabby/Gabriel (F or M Gabriel) and Bebe/Bobbart (F or M Beezlebub) as their leaders.

Aziraphale has but one secret, which is something that he's promised not to ever to tell anyone because Crowley made him swear on it, who is the only living person that he's ever told it to.

On that night, when the strudents were asked upon questioning, Aziraphale had lied about what he knew.

He revealed this to Crowley when those two students were brought home and their friednship lasted for a very long time in secrecy.

["I lied," Ezra whispers in a hushed tone*.

"You what?" Crowley asks.

"I lied!" He repeats to stand his point.]

*Original scene from the series Good Omens.

+Note: Six thousand years of knowing each other, you would think that in a Human AU they would probably only know each for six years. At a bare minimum, they've only encountered each other because of the ridiculous situations that their two sides have made. So, no. I don't think so.

Their school history is a resemblance to that of what is depicted as every disaster and triumph ever known to mankind. So, they would probably have known each other since little infants, and that they went through a lot together until the sixth grade. They held the fight for nearly six years until graduation.

Teachers were well aware of the situation and don't necessarily try to interfere with such matters as they cannot control.

Details

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). 

Imagine Aziraphale and Crowley dancing to Billie Eilish’s “bad guy” like Aziraphale will be doing the gavotte while Crowley is just like “this is demon freestyle right here!” 

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