This is my first fanfiction, so let me know how badly I suck. In the future I plan to write more slash... not sure who with...

WARNING, THIS STORY CONTAINS SLASHY YUMMYNESS! THAT MEANS MAN ON MAN! Exit now if you don't want that.

DISCLAIMER: I don't own Batman or The Avengers any of the sort, 'cause if I did, I'd be rich by now...

Chapter One: What just happened?

"You wouldn't dare." Joker spat out at his foe.

They were in the middle of one of their typical battles. It came to that point where Joker's life was on the line. But, of course, the masked man wouldn't take a life, not even from someone like the Joker.

Batman glared at him. He knew all too well that the clown was being truthful. The masked vigilante looked closer at the vat of chemicals that the man he loathed was on the edge of. Looked like the chemical inside couldn't decide whether is was a solid or a liquid. One second it would be liquid, the next like gelatin, the next almost plastic. He most certainly couldn't push Joker in.

"He may not be able to, but I can!" shouted a civilian who must have been watching from the sidelines the whole time.

Batman watched in horror as the the civilian, who looked only to be around 17, threw some object at Joker with stunning accuracy. He jumped, trying to catch the object before it hit Joker, but missed it, just barely. It hit Joker, who's eyes were just as wide as Batman's, knocking him backwards. Joker shrieked, and fell into the vat of unknown chemicals.

Being in the chemical was unlike anything Joker had ever experienced before. At first it only felt like water, but then in turned into gelatin around him. before her knew it, he was stuck in a position because it turned into a soft plastic. The clown writhed around until he eventually swallowed a small amount of it. The substance was liquid halfway down, gelatin the other half, and like a rock when it got to his stomach. Even though Joker felt horrible with it in his stomach, he tried his best to 'swim' upwards.

When he finally managed to get his head out of the goo, he gasped for air and looked around. Neither Batman nor the civilian were found. He grunted and pulled himself upwards. He wasn't wet, oddly enough. Joker managed to stand on the edge of the vat again.

"What is that stuff?" He allowed himself to wonder aloud.

All of a sudden, Joker got the weirdest feeling, and before he knew it, he was short! And furry! He tried to speak, but only got out a loud "Ruff!".

He got the weird feeling again and was suddenly very small, with a thousand eyes! He was turning into different animals! Next was an alligator, then a giraffe, then a deer. The speed at which he was changing was rapidly increasing, until he couldn't tell what he was anymore.

The speed kept increasing, and increasing, until-

Joker blinked and was somewhere different. He was human again, but in an unfamiliar place. He wasn't sure whether he should be happy or upset. It appeared that he was in a deserted park. Joker wondered why it would be deserted, because it looked so nice and green. He also noticed that his stomach didn't feel odd anymore, almost as it the weird chemical had gone.

Joker looked around for anyone that might be able to tell him where he was. Nobody. "Guess I have to explore." he mumbled.

Okay then... so, be sure to make a review telling me your honest opinion about how I did, and what I could fix. I'll keep working on this story, and hopefully, I'll finish it. That may not sound like an impressive feat now, but to me it will be, because that would mean it's the first story I've finished. Thanks!
