Prologue

Spider-Man swung from one building to another, frantically searching for the madman who'd been causing havoc all day. Where the hell are you Wade?

The young hero landed on the side of one building, trying to reach out with his spidey-senses. Nothing. Obviously he wasn't anywhere near…wait, what was that? Peter focused for a moment, then immediately jumped out of the way as a large plant burst through the wall he'd just been clinging to. "Jeez, can't it just be one bad guy at a time?" asked Spider-Man, landing on a balcony of a building across the street.

"Move it kid, I have things to do," said a woman's voice, and Peter suddenly noticed a woman with red hair, green skin, and wearing a green one-piece was standing on the plant.

"Sorry lady, but I'm pretty sure breaking a building with a tree is against the law," said Spider-Man. "I'm going to have to ask you to stop doing that."

"I wouldn't advise stalling me," said Poison Ivy. "I'm in the middle of stopping someone much more dangerous causing much more trouble."

"Wait, you're trying to stop Deadpool too?" asked Spider-Man.

"Who? No, I'm looking for my friend Harley," said Poison Ivy. "You know, wears a lot of red and black, probably carrying a large gun…"

"You literally just described Deadpool," said Spider-Man. "And that's who I'm trying to…" Before Peter could finish his sentence, a loud explosion rang out through the city, causing the two of them to stop and stare.

"Harley/Wade," they said at the same time, before heading off towards the explosion.

Author's note: Yay, I get to do a new fanfic. AND it features Deadpool. This fic is going to be about Deadpool and Harley Quinn meeting up and deciding to cause havoc together. I plan on having a LOT of DC and Marvel characters cameo (including one cameo I plan to sneak past the Fanfiction dot net censors). If there's any specific character you guys would like to see appear, feel free to let me know (I've got a decent list already, but it can always be longer). Until next time guys…
