Chapter 1: The Merc with a Script: Welcome to the Crossover

The office was an eclectic mix of modern minimalism and chaotic creativity. Neatly stacked papers, concept art, and figurines of spiky-haired heroes lined the walls, while the desk was littered with sketches and crumpled notes. The centerpiece, however, was a large, plush leather chair, its back turned to the room. Soft light filtered through the blinds, casting long shadows that stretched across the floor, giving the space an almost otherworldly feel. The air was thick with the scent of ink and old parchment, as if the very ideas birthed in this room had left an indelible mark on the atmosphere.

The space seemed to hold its breath, waiting, as if the creative energy within it was merely dormant, poised to spring to life at any moment. Above the desk, pinned to the wall, hung a single drawing—Aqua, the steadfast Keyblade Master. Her blue eyes, though carefully sketched, appeared haunted, burdened by a thousand battles and an equal number of regrets. It was a striking image, capturing a fleeting moment of vulnerability in a character defined by her strength and resolve.

From somewhere behind the chair, a voice emerged, deep and contemplative, each word weighed down by its own gravity.

"In the end, every heart returns to the darkness whence it came. But what if it's not darkness at all? What if it's something much… stranger?"

The chair swiveled slowly, revealing not the enigmatic creator of Kingdom Hearts, Tetsuya Nomura, but someone far less predictable and infinitely more chaotic.

Deadpool, the Merc with the Mouth, lounged comfortably in the chair, his red and black suit catching the dim light as it glinted off the twin katanas strapped to his back. In one hand, he clutched a script so massive it looked like it could double as a weapon fit for a Keyblade Master. With a casual flick of his wrist, he spun the script lazily, like a bored executive toying with a pen, his demeanor as relaxed as if he were simply killing time between blockbuster gigs.

"Oh, hello there!" Deadpool greeted with his trademark grin visible through his mask. "You didn't think Nomura-san was here, did you? Nah, he's a little… tied up at the moment. Probably off somewhere cooking up another dozen sequels where we all pretend to understand the plot."

He gestured nonchalantly toward the drawing of Aqua on the wall, tilting his head as if considering the image.

"Look at her. Poor Aqua. From a legendary Keyblade Master to a drawing on some fan fiction writer's wall. And me? From making billions at the box office with my pal Hugh 'Freaking' Jackman to… well, this."

He sighed dramatically, letting the irony of the situation hang in the air for a moment.

"The irony is just dripping off the walls, isn't it? Here I am, a PG version of myself, stuck in a crossover that not even the most desperate Reddit thread could have predicted."

Deadpool flipped through the script with a groan, the pages fluttering noisily.

"This thing's a beast. And let me tell you, it's full of words I'm not allowed to say. Seriously? I can only say 'damn' and 'crap' a few times? What is this, a 1990s episode of The Simpsons? Ha! I can say that now without worrying about IP infringement. The Disney-Fox merger really does have its perks. But, I digress. The show must go on, and you're stuck with me as your guide through this wild ride."

Deadpool tossed the script onto the desk with a satisfying thud, leaning forward as if to share a secret.

"Now, let's get one thing straight, dear reader. I know exactly what this is. You're here for a fan fiction—a crossover of epic proportions. And me? I'm the star of the show. Sure, Aqua's gonna get her moments, all tragic and noble or whatever, but we all know who you really came to read about."

Deadpool leaned back once more, propping his feet up on the desk, a smug grin spreading beneath his mask.

"Now, I know what you're thinking. Deadpool, why Aqua, right? Why not Sora, the spiky-haired poster boy of confusion? Or Riku, the brooding, silver-haired heartthrob of Keyblade wielders? Maybe Roxas, the angsty boy with identity issues? Heck, even that dude voiced by Quinton Flynn—Axel, Lea, whatever his name is these days—would've been a solid pick. And let's not forget Miss Underdeveloped Character Arc herself, Kairi. Yeah, she's been around since day one, but let's be real, the poor girl's been more of a plot device than an actual character."

The Merc paused for a moment, letting his audience process the whirlwind of Kingdom Hearts references.

"But here's the thing," he continued, leaning forward as if to share a juicy secret. "This wasn't just some random pick out of a hat. No, no, this was an executive decision. You see, the powers that be, those shadowy execs pulling the strings, thought it'd be too predictable to go with one of the usual suspects. And besides, Aqua's got this whole tragic, misunderstood hero vibe going on. It's like the perfect setup for one of those redemptive arcs that people eat up like chimichangas."

Deadpool paused, tapping his chin thoughtfully.

"Plus, there's this other thing… Blake told me to team up with her. Yeah, that's right. Gossip Girl herself whispered in my ear—'Go for the blue-haired badass, Wade. It'll be a crossover for the ages.' And when Blake speaks, you listen. At least, if you know what's good for you."

Deadpool leaned back in the chair, a grin tugging at the corners of his mouth from under his red and black mask.

"So, buckle up buttercup. This isn't just your regular fan fiction. It's got everything—meta jokes, universe-altering stakes, and a protagonist who's fully aware that this is all just some writer's fever dream. But hey, who am I to judge? Let's see where this rabbit hole goes, shall we?"

He glanced back at the drawing of Aqua, his tone softening just a fraction.

"And Aqua… don't worry, girl. We'll get you out of this mess. Even if it means breaking a few rules along the way."

With a flourish, Deadpool leaped out of the chair, producing a pen from seemingly nowhere—because of course, he had one—and proceeded to scribble a quick doodle on the drawing of Aqua, adorning her with a mustache and a pair of oversized sunglasses.

"There. Now we're ready."

He turned his attention back to the reader, pointing the pen directly at the page as if addressing them personally.

"Let's get this fan fiction party started, folks. And remember, if things get too weird… well, that's just how I like it."

In a dramatic moment, Deadpool reached up and peeled off his mask, revealing the face beneath—scarred, rough, and unmistakably his. His skin was mottled and uneven, a testament to the healing factor that kept him alive but did nothing for his looks. His eyes, though shadowed by deep lines of exhaustion, still gleamed with that signature mischievous spark. He smirked, fully aware of the reaction this face usually drew.

"It's like looking at Ryan Reynolds mixed with a Shar-Pei, right?"

Deadpool paused, letting the irony of the situation hang in the air for a moment before offering a final, roguish wink.

With a swift flick of his wrist, he pulled the mask back down, the familiar red and black fabric settling into place as he relaxed into the chair once more. He twirled the pen in his hand with the ease of someone who'd been wielding a Keyblade all his life, a devil-may-care grin hidden beneath the mask.

"After all," he mused, leaning back with an air of nonchalance, "what's the worst that could happen?"

WN: Just a quick note before you dive into this madness—I hope you enjoy every chaotic moment of it. This is just a fun crossover, born from my love for both Marvel and Kingdom Hearts. With the success of Deadpool Wolverine, I couldn't resist the temptation to bring together my two favorite characters from my two favorite franchises: Deadpool and Aqua. It's a wild ride, hopefully full of fourth-wall-breaking humor, epic battles, and a whole lot of heart. So, sit back, relax, and please enjoy this crazy adventure!
