Chapter 1

Delaying the Inevitable

Four Years After the Series Finale

LOVEMUFFIN HQ

5 P.M

Doofenshmirtz and the rest of Perry's OWCA occupy the outside of LOVEMUFFIN's HQ. Perry reloads his laser gun and aims at the door. He means to shoot it down, but the now 9-year-old platypus can't do it.

For those who didn't watch the series finale, Doofenshmirtz gave up evil and joined OWCA. With Doofenshmirtz out of the picture, Perry was assigned a team of trainees, including Doofenshmirtz, to conquer evil.

He shows wrinkles under his worsening eyes. Perry's vision is blurry, and he can't properly aim. Doofenshmirtz groans and grabs Perry's laser gun; he uses it to blow up the front door.

"Freeze!" Doofenshmirtz yells as him and crew sprint inside the building; Perry rubs his aching knee joints and scampers towards the blown-up entrance.

Aloyse von Roddenstein holds a laser gun to Perry's team. His hands are shaky.

"What do you guys want?" he asks and maintains his aim.

"We're here to bust your operations" Doof tells them. "You have a million dollar order for evil Inators-"

"-Nobody else calls them Inators-"

"-Whatever" Doofenshmirtz interrupts. "We're gonna destroy the Inators before this deal happens"

Aloyse looks back at his crew and yells, "Run!"

The entire LOVEMUFFIN team evacuates the building through the back doors. Along with them, they remove the evil machines and some of their blueprints from the back doors.

"Darn it!" Doofenshmirtz yells.

Perry motions the team to chase after those escaping with the equipment. The team abides and Perry glares at a still-standing Aloyse.

"What are you gonna do?" Aloyse cracks his fingers and gives a smirk.

Perry glares at Aloyse and gives him an uppercut, surprisingly knocking Alyose onto his back.

"Ow..." Aloyse groans as he lies on the floor.

Perry wheezes as he approaches the knocked-down being. He grabs his fedora and pulls a pair of handcuffs out from it.

But, suddenly Perry's shortness of breath worsens. A sharp pain emerges from the platypus' chest. He clutches it and collapses to the ground.

"HAH!" Aloyse laughs and gets up. He stares over Perry's dying body.

The platypus sweats and his eyes are half-open. He tries to move, but alas it fails, and he remains mobile.

"PERRY THE PLATYPUS!" Doofenshmirtz roars from across the room. The other teammates enter from the back door. They have the other LOVEMUFFIN members in handcuffs.

Doofenshmirtz runs towards Aloyse, who points the laser gun at Perry's head.

"Release my colleagues or the platypus dies!" he blackmails Doofenshmirtz.

"You're bluffing" Doofenshmirtz rejects with a shaky voice, too scared at this point about the outcome.

Aloyse reloads his laser gun and is ready to pull the trigger.

"No. Wait!" Doofenshmirtz surrenders and puts his hands up. The former villain looks back at Perry's team and sighs: They release LOVEMUFFIN's members from their handcuffs.

Perry cough worsens and he struggles to keep his eyes open.

"Now get out of here!" Aloyse orders them and kicks Perry onto his side. "Get this poor creature to a vet"

Doofenshmirtz runs towards Perry and leaves the premises with the team.

OWCA: Pet Hospital

7 P.M

Perry rests on the hospital bed. Fortunately, nobody's home and is waiting for Perry to come home. The boys are on a school trip, Candace is studying abroad for college, and the Flynn-Fletchers are gone on a cruise.

Stacy Hirano's pet setting for Perry, but she knows Perry's secret without OWCA's knowledge. She doesn't worry too much about him. Wherever he is, Stacy knows that he's on a mission and will return soon, except this time.

"None of his family members are home for a week" Major Monogram discusses with Doofenshmirtz. "He can rest here"

"No. Somebody's pet-sitting for him" Doof explains, recounting an earlier conversation with Perry. And by conservation, that means Perry writing his speech on a notepad.

"Darn it. We need to rush his treatment" Major Monogram comments, completely unaware of Stacy's knowledge.

Doof hovers over Perry's unconscious body and sighs. "It's his 2nd heart attack this year. He's gotta retire"

"But, he's our best agent" Major Monogram disagrees. "Well, he was our best agent...until he turned 9. That's 56 in human years"

Major Monogram then sighs and thinks for a minute. He nods.

"Here's what I'll do: Agent P will retire. And you'll lead his team"

Doof gives a shocked expression: "I don't know if I can handle that. It's too much pressure"

"You'll be fine"

Seven Years Later

Danville Vet Office

"How long does he have to live?" an elderly Mr. Fletcher asks. He sits in the vet's office along with his wife. None of the children could make it. The boys are in college and Candace works abroad now.

Perry lies in the portable pet cage. He can barely keep his eyes open. He can barely walk let alone crawl on all fours. The platypus looks extremely thin and pale. The little hairs on his forehead have turned white.

The vet breaks the news. "One week"

The Flynn-Fletchers shed tears and their mouths are gaped. Ms. Flynn leans on her husband's shoulder for comfort. He brushes her forehead. But then he breaks down himself.

"I'll let the kids know" Ms. Flynn says.

Four Hours Later

1 A.M

The Flynn-Fletcher Residence

The Flynn-Fletchers sit on the couch. Perry remains in the pet cage, which is set to the side of the couch. Ms. Flynn converses with Candace over the phone.

"Phineas and Ferb are looking for flights back home. Yeah, just thunderstorms until next week" Ms. Flynn asks over the phone. "Alright, sweetie. Just call me as soon as you book one"

She hangs up and faces her husband. "It'll be a blessing if they can be here...for Perry's final moments"

A couple of minutes pass. To take their minds off the sadness, they turn on the TV. Coincidently, the TV turns onto the news channel.

"LOVEMUFFIN just sold $1 billion worth of evil equipment. This just worsens the crime rate in Danville, which has spiked in the past 7 years" the anchor announces. "Why hasn't the police done anything about this crime rate? Who can stop LOVEMUFFIN?"

Perry just stares at the news from his pet cage. His eyes widen and a sense of guilt emerges, despite his inability to do anything.

The Flynn-Fletchers turn off the TV and the lights. They head upstairs to their bedroom.

With great difficulty, Perry opens the cage and crawls towards the pet door attached to the bottom of the back door.

One Hour Later

Doofenshmirtz Not Evil Incorporated

Doof's stripped down to his pajamas. He sits at his work desk and talks over the phone. "Alright, LOVEMUFFIN is pushing my buttons. But we can infiltrate their cargo site tomorrow morning before it ships"

Someone knocks on the door; Doof notices.

"Thanks for the approval, Monogram" Doof thanks him and hangs up. He sprints towards the door and notices a sickly Perry. He wheezes and clutches his aching knees.

"Perry The Platypus? We're not scheduled for Checkers until the afternoon" Doof asks, confused. "Actually, we're infiltrating LOVEMUFFINs cargo site tomorrow morning, so that might need to be cancelled"

Perry doesn't listen and glares at him.

"I feel like you want something" he understands.

Perry scampers towards Doofenshmirtz's closet. The closet door has the label "UNTESTED INATORS" slapped on the top.

Doof runs towards his drawer. From inside, he grabs a notepad and pencil; he hands them over to Perry.

Perry notes down. "I want your De-Age contraption"

He hands the note to Doof. Doof reads it and says no. "Perry. I never tried the De-Age Inator. Using an Inator is illegal and could have disastrous effects on your body!"

Perry crosses his arms and just stands there, but not for long as his knees ache again.

"Perry. The answer's no!" Doofenshmirtz gives a final answer. Then, thunders erupt in the dark sky.

"Alright, you're not going home in that weather" he tells him. "If you want, then sleep on my couch for the night"

One Hour Later

Doofenshmirtz's Living Room

Perry lies on the couch. His back aches terribly. The almost 17-year-old platypus just stares at the same closet. It perfectly faces the couch. Once he can hear Doof snore from his open-door bedroom, Perry sits up.

His back cracks and he stands on the ground. The platypus takes baby steps towards the closet, ensuring to not overwork his aching knees.

Perry grabs the closet's door handles and pulls.

'Wow. That was stupidly easy' Perry thinks to himself. He scratches his head and finds the De-Age Inator resting on the middle shelf. It's an injection.

Perry doesn't even hesitate. He just injects the purple syrum into his arm. He screams and collapses to the ground.

Doof gets up and notices Perry collapse on the ground.

"PERRY!"
