A/N: I thought up of this fanfic while I was watching the episode "Greece Lightning" online. It all started while I was watching it, and one particular scene caught my interest. It was where Phineas and Ferb are racing down the street in their chariot, with Buford and Baljeet's chariot as well as that of Isabella, Katie, and Holly's right behind them. I saw Phineas and Ferb's faces, and they both had looks of determination on them (well duh, they were trying to win the race!). But I was rather interested in how Phineas's face looked, and I commented to myself, "Wow. Phineas sure looks a lot like Doofenshmirtz with that look." When I finished watching the episode, I kept thinking about that look Phineas had during that scene, and I suddenly settled on a random thought: "What if Phineas turned evil?" And lo and behold, I found myself writing this down!

This is my first fanfic, so if something seems off, then please bear with it.

Okay, I think I'm rambling. On to the prologue! ENJOY!

Disclaimer: I DO NOT own "Phineas and Ferb"! Only in my dreams!

(Edit) Prologue Summary: Perry concludes another day of fighting Dr. Doofenshmirtz, while Doofenshmirtz hatches another scheme.

It was a peaceful night in the city of Danville, U.S.A. The full moon was present in the cloudless sky, bathing the city with brilliant rays of moonlight. Downtown was as busy as ever, while the suburbs were very quiet, save the occasional chirp of a cricket or bark of a dog.

However, it wouldn't have been that way had an extraordinary platypus living at 2308 Maple Drive not acted.

This platypus, named Perry, thought about what occurred during the past several hours as he rested on one of his owners, Phineas Flynn. It had just been last morning when his superior, Major Francis Monogram, assigned him to help his colleagues at the O.W.C.A. stop the League of Villainous Evildoers Maniacally United For Frightening Investments in Naughtiness (a.k.a. L.O.V.E.M.U.F.F.I.N., humorously) from enacting its master plan to conquer the Tri-State Area. Never before had Perry seen his arch-nemesis and the leader of L.O.V.E.M.U.F.F.I.N., Dr. Heinz Doofenshmirtz, come so close to achieving his goal aside from the time he constructed the Other-Dimension-Inator. It was a good thing Doofenshmirtz set a bear-sized cage trap on Sergei the Snail.

Looking at Phineas, Perry smiled. When he was told that he was meant to become a secret agent for the Organization Without a Cool Acronym, Perry privately vowed to become one so he can prevent any harm from coming to his host family, especially Phineas and his stepbrother Ferb, the both of whom he became close to ever since they first bought him from the O.W.C.A. pet shelter five years. Perry can still imagine the two boys originally planning to call him 'Bartholomew'.

However, Perry sometimes wished that he was allowed the liberty of exposing his secret to his owners. He was able to, but for a good reason: Phineas and Ferb were about to be assaulted to a robotic version of himself, and he had to act. But now, the two boys are unable to remember what happened during that fateful day from particular circumstances. Perry was glad it happened, otherwise he would have to be sent to a faraway town and another host family for Phineas and Ferb's safeties, but how he wished there was a third option.

Shifting his glance from Phineas to Ferb, Perry knew that it was all for the best, and that yet another day of protecting the two boys was spent well, and that the forces of evil wouldn't be able to hold them in its grasp until tomorrow.

With his sight becoming blurry from sleepiness, Perry immediately surrendered and allowed the comfort of sleep to engulf him.

Yep, this was his life, all right.

Doofenshmirtz Evil Incorporated! In the nighttime!

Dr. Heinz Doofenshmirtz couldn't sleep tonight. Today had been a rather hectic day for him. It all started when he gathered his followers in another L.O.V.E.M.U.F.F.I.N. meeting to enact their plan to take over the Tri-State Area. The meeting was interrupted by the O.W.C.A. agents, including his own arch-nemesis, the accursed Perry the Platypus. Fortunately for him, he was prepared: he set cage traps on every animal agent, and success was in reach of the malevolent organization. Unfortunately, he didn't count on the O.W.C.A. sending the same snail agent they temporarily replaced Perry with, and the snail had to be contained in a cage that was intended for a bear agent who was absent at the time.

What's worse, right after the latest failure of L.O.V.E.M.U.F.F.I.N., every member was upset with him for his foolish mistake. Doofenshmirtz began to fear that either the organization will be disbanded or that a new leader will be assigned. If the latter choice was true, then Doofenshmirtz hoped that they wouldn't vote for Rodney, his rival.

Doofenshmirtz's thoughts were interrupted by his doorbell ringing.

"I'll answer that!" came the optimistic, robotic voice of his robotic servant Norm.

A few seconds later, Doofenshmirtz heard the sound of wood breaking and metal being crushed.

"Oh, not again Norm!" groaned the evil scientist as he made his way to the front door. Norm stood beside it, holding the now-crushed doorknob in his hands; a piece of wood was attached to it.

"I'm sorry, sir," Norm replied, still optimistic.

Doofenshmirtz sighed angrily and procured a ray gun from his pajamas. He fired at the door, which swung open immediately, revealing his fellow L.O.V.E.M.U.F.F.I.N. members, all bandaged from fights with the O.W.C.A. agents earlier. They were led by Rodney, bandages wrapped around his ridiculously large head.

"Hey, everyone!" Doofenshmirtz greeted, hoping to settle on a positive subject. "Do you like my Door-Opener-Inator? I thought it up when-"

"Enough of your ridiculous back-stories, Doofenshmirtz!" Rodney scolded, cutting the other evil scientist off. "We all willingly woke up in the middle of the night so we can come here to talk about what went down earlier today!"

"Yeah!" said a red-haired scientist. "About our latest failure, all because of a snail and a bear-sized cage!"

"Settle down, Dr. Bloodpudding," Doofenshmirtz said wearily, "I can explain!"

"We don't care about your explanations, Doofenshmirtz," Rodney replied. "While we were up on our way to your place, we all had a discussion, and we unanimously agreed to revoke you of your status as the leader of L.O.V.E.M.U.F.F.I.N.!"

Doofenshmirtz felt as if the ground collapsed beneath him. "What?" he shrieked. "But I founded it! I'm its leader!"

"Sure, you founded it," said a woman with brown hair oddly shaped like a helmet. "But you don't live up to our expectations as the organization's megalomaniacal leader!"

"I am megalomaniacal, Helmetair!" protested Doofenshmirtz. "It's just that my accursed nemesis Perry the Platypus keeps thwarting my plans every day! You all should know how I feel, you have a nemesis that's an O.W.C.A. agent!"

"We've thought about that too, Doofenshmirtz," Bloodpudding said, "and we've decided, for your sake, that no one's gonna be leader of L.O.V.E.M.U.F.F.I.N. Not until we find a truly evil villain who will help us achieve success in our goal to conquer the Tri-State Area and enslave its inhabitants!"

Suddenly, a light bulb practically went off in Doofenshmirtz's head. A marvelous idea swept his mind, a wonderful, marvelous idea. How come he never thought of it?

"Or," said Doofenshmirtz, "we can make a truly evil villain who will help us achieve success in our goal to conquer the Tri-State Area and enslave its inhabitants!"

"What do you mean make?" Rodney asked.

"I can just reconstruct my Turn-Everything-Evil-Inator and use it on myself so I can become even more evil!" Doofenshmirtz explained. "Foolproof, isn't it?"

The nine other scientists just stared at him before bursting into fits of laughter.

"What? Is it because I said this in my pajamas?"

"No," replied Rodney when he stopped laughing. "It's just that you said your nemesis Perry the Platypus foils your plans every day. Chances are he's gonna come and thwart you again, Doofenshmirtz!"

"Now that you mention it, it's plausible," Doofenshmirtz said. "Which is why I'm appointing you all to help me in my scheme!"

The rest of L.O.V.E.M.U.F.F.I.N. stared at him before a short scientist asked, "How?"

"Easy, Diminuitive. Some of you can help me reconstruct my Turn-Everything-Evil-Inator, while the rest can stand guard for Perry the Platypus!"

The rest of the scientists looked at one another before reluctantly nodding and giving signs of approval.

"This had better work, Doofenshmirtz," Rodney said as he left the room, followed by the rest of the villains. Doofenshmirtz prepared to close the door when he realized it was still damaged.

"Great," he said. "I still need to repair this thing before I get back to sleep. Norm, get me my toolbox!"

"Yes, sir!" the robot replied, striding off to retrieve Doofenshmirtz's desired object.

With Norm out of sight, Doofenshmirtz quietly snickered to himself evilly.

"Soon," he thought. "I will become truly evil, and the Tri-State Area will soon be under the control of L.O.V.E.M.U.F.F.I.N.! Not even Perry the Platypus can stop me this time!"

A/N: I think you can now see where this is going. Don't worry, it gets more interesting as it goes. By the way, if the fanfic's premise seems all too similar to another fanfic, please tell me, because me ripping off another's work was purely unintentional. Give me the story's name so I can read it and find out how I can make my work entirely different from it. Personally, I think that the premise is a bit similar to "Personality Flynn" by Doverstar, but since Phineas doesn't actually turn evil in that story, I think that's cleared up.

Well, hope you enjoyed this prologue! TheCartoonFanatic01 is out. PEACE!
