Good evening ladies and gentlemen! I will be tonight's entertainment!

So, this is my first ever Fan-Fiction! Hooray for me! I hope that it isn't too weird, that it's reasonably well written, and that you all enjoy it. I'm always open to constructive criticism, so please review!

Oh, and I'm going to warn you right now: my update times probably won't be the fastest. I will try to post as often as I can, but there's a lot going on, other than just writing this story. So, as I said, you've been warned.

Disclaimer: I don't own Phineas and Ferb, or Batman. They, and all associated characters, belong to Disney, and to DC Comics, respectively.


Prologue


A Stranger walked through Gotham. It was not his first time there. He came as an observer. He watched as a Clown and a Bat prepared to do battle once again. But this time, there would be something different; a different soul on the line, new players in the game.

In another part of the city, the Girl Jester made her own plans, having no way of knowing how intertwined they were with those of the Clown and the Bat, the two beings she wished to avoid more than all others on this night.

In a prison of the mind, a Doctor sat, and studied. He studied the ill, the imprisoned. A Milliner. An Animal. A Genius. A Seductress. A Killer Among Killers. And even, another Doctor. All of them mad, each in their own ways. Even the Doctors, both of them.

And finally, next to a Signal, stood a Commissioner, waiting for a Bat. Together, they had dealt with all of the mad in their city, and they felt safe because of it.

The Stranger saw all of this, and knew that none of them were prepared for what was to come. It would change the Game. Forever.


A Stranger walked through Danville. It was his first time there. He came as an observer. He watched as children played, making their toys for the day. But this time, there would be something different; a darker place to play, more dangerous toys to build.

In a yard, an Inventor built his toys. He built with his friends. A Bully. A Nerd. A Girl. And even, another Inventor; A Brother. All of them had parts to play, large and small. Especially the Girl, and the Inventors, both of them.

In another part of the yard, the Girl talked to an Inventor. She wished only for him to notice her, having no way of knowing just what it would take for this wish to come true. How each of their paths intertwined with another, darker, one.

Across the city, a Scientist and an Agent did battle, once again. The parts they had to play were perhaps the most, and least important. Without them, none of it would be possible. But ultimately, they would have no more power over the outcome, than the Stranger himself.

And finally, a Teenager stood and watched, waiting for her mother. She had seen all of the Inventor's toys, and felt half-mad because of it. She wished only for other's to see what she saw. She could not know that soon, even She would not see the Inventor's, or their toys. She did not realize that soon, she would seek to save, rather than to destroy them.

The Stranger saw all of this, and knew that none of them were prepared for what was to come. It would change the Game. Forever.


The Stranger came once again to Gotham. This time, he came as a harbinger.

He came to give what little warning he was allowed, to the Bat. The Stranger found the Bat in his cave.

"Batman. We meet again, though I wish it could be for happier a cause."

The Batman turned to face the Stranger. "Phantom Stranger. To what do I owe the honor?"

"You may dispense with the pleasantries Batman. My time here is brief, and I have important things to tell."

"What is it this time? An alternate world where the heroes are villains? Information on an old foe you want me to track down?"

"I'm afraid it is nothing so simple Batman. I am not able to go into much detail, but I come with a warning."

The Batman regarded the Stranger, expressionless. Phantom Stranger had helped in the past, to an extent. But his arrival always seemed to herald some kind of struggle; He never seemed to have good news. Whether or not the eventual outcome was good, which it nearly always was, it always took going through Hell and back to reach it.

"What is then?"

"Two worlds are about to meet, for the first time. A boy's soul hangs in the balance, as yours once did. You will be pivotal in deciding which way the battle goes. Regrettably, your greatest foes will be perhaps, even more decisive. Ultimately, the boy will have nothing to rely on but himself, and his friends. You will be unable to help him, except by helping his friends to do so. The battle will be dark, and hard. Evil and Madness will rise, stronger than ever. You must do what you can to stop their advance."

"Is that all?" asked Batman, incredulously. Of all of the things the Phantom Stranger could have said, he would never have expected this.

"I understand your bewilderment. This will not be an easy time, for any of you. Regrettably, I cannot tell you more. I am, as always, merely an observer; a Stranger in this game. But I can give you one piece of advice. A warning: Do not be too quick to mistrust your foes. In this coming battle, you may find allies in the most unlikely of places."

With that, the Stranger vanished, leaving Batman to ponder what he had been told.

Suddenly, he saw a warning appear on his computer screen: A breakout from Arkham. And out of all of the lunatics it could have been, it had to be the Clown Prince himself, The Joker. Between that, The Phantom Stranger's warning, and Quinzel still on the loose since she escaped last month, things were not exactly looking up.

"Alfred," he said, into a speaker, "would you have my dinner brought down here? It looks like it's going to be a one of those nights."


Well, there you go! I hope this isn't too weird for anyone so far. Trust me, all of the chapters won't be this cryptic. This one was just from the point of view of the Phantom Stranger, so it had to seem a tad mysterious.

Well, I hope I left everyone in suspense. Don't worry, the Phineas and Ferb gang will be in the next chapter.

So, please review!

(And as I said earlier, update times could get a tad, shall we say, spotty, but I should be able to get at least the next chapter out pretty soon!)

Keep Smiling!
