The warm afternoon sun filtered through the window as Multi Nana-iro sat on the edge of her bed, legs crossed, eyes glued to the television. The latest episode of Pokémon Journeys blared from the screen, and her excitement was palpable as she watched Ash Ketchum stand triumphantly on the stage, the cheers of the crowd echoing in her ears.

"Ash Ketchum, the world champion... At his age, he's already accomplished so much!" Multi whispered, her voice a mix of awe and admiration. "If only I could be that cool... I could totally pull off that look."

Her mind began to race with possibilities. What if, just for a day, she was Ash Ketchum? The world champion who battled with courage, determination, and a constant drive to improve. Her Beyblade battles had always been fueled by the same spirit—she could bring that to life! Maybe even take a little inspiration from his style...

With a determined grin, Multi stood up. "Alright, it's time for a new challenge."

A few hours later, Multi stood in front of her full-length mirror, admiring her new look. She had pulled together the signature outfit from Pokémon Journeys—the same red and white jacket, the cap, the fingerless gloves, and the black sneakers. The look was complete... well, almost. Instead of Ash's typical casual jeans, Multi stuck with her own signature gray shorts and leggings, as they were more her style. She even topped it off with her signature gray headband, which had small horns attached to it, a quirky touch she had kept from her usual attire.

"Perfect!" she exclaimed, spinning around. "I'm ready to take on the world!"

Meanwhile, in the Beyblade arena, Robin and Blader X were having a conversation about the upcoming tournament. The two were well into their training when Multi burst in through the door, her eyes wide with excitement.

"Ta-da!" she exclaimed dramatically, throwing her arms wide.

Robin blinked, his expression somewhere between confusion and amusement. Blader X, standing next to him, tilted his head, his sharp gaze scrutinizing Multi's outfit with the precision of a seasoned blader.

"Uh… Multi?" Robin began, raising an eyebrow. "What in the world are you wearing?"

Blader X crossed his arms, a slight smirk playing at the edges of his lips behind his X mask. "Is that... is that Ash Ketchum's outfit? From Pokémon?" he asked, his tone laced with both disbelief and curiosity.

Multi nodded enthusiastically. "Yep! I'm Ash Ketchum today! The world champion!" Her black eyes sparkled with excitement, and her rainbow-colored streaks in her hair seemed to shimmer as she beamed at her friends.

Robin blinked again, clearly unsure how to react. "But… Multi, you're a blader. Why are you cosplaying as a Pokémon trainer? That's not exactly how we do things here."

"Exactly!" Blader X interjected, "You're a beyblader, not a Pokémon trainer. You don't need to be running around in someone else's gear."

Multi's grin didn't falter. "That's the point! Ash Ketchum is a champion. And he didn't just become one by sitting around. He trained hard, and he faced challenges head-on! I want to channel that same energy when I compete. I'm not just Multi Nana-iro anymore… I'm Multi Ketchum!"

There was a long pause as Robin and Blader X exchanged a look.

"You're serious, aren't you?" Robin finally said, shaking his head with a half-laugh. "Okay, okay. If this is how you want to do it, who are we to stop you? But don't expect us to call you Ketchum in the middle of a tournament."

"Deal!" Multi said, grinning from ear to ear. "And guess what? My next challenge—" She held up her Beyblade, the light catching the edges of its design. "I'm taking this to the next level. I'm going to win with the same spirit Ash has in every battle!"

Blader X snorted, clearly amused but skeptical. "You really think dressing up like that is going to give you some magical edge in your next match? You can't just pretend to be someone and expect to win."

"Watch me!" Multi shot back, her voice full of fire. "Just you wait, Blader X. When I unleash my Beyblade with the heart of a champion, nothing's going to stop me!"

A few hours later, Multi stood in the Beyblade stadium, ready for her next match. The arena was packed with spectators, and her opponent, a seasoned blader named Ryo, was already standing in his designated spot, looking at Multi with a bemused expression.

"You sure you're ready, kid?" Ryo asked, eyeing her costume. "You're dressed for a Pokémon battle, but this is a Beyblade tournament. You might want to focus on the game."

Multi grinned, adjusting her headband. "You have no idea what you're up against. Let's do this, Ryo!"

The announcer's voice boomed over the speakers. "And now, we have Multi Ketchum—uh, I mean, Multi Nana-iro—versus Ryo! Let's get ready to rumble!"

With a dramatic flick of her wrist, Multi launched her Beyblade into the stadium, and the battle began. It was a blur of spins, clashes, and rapid movements as the two bladers went head-to-head, their Beyblades darting and bouncing across the arena.

Multi's every movement was precise, her confidence radiating from her as she channeled the same energy she had seen in Ash. Each move was calculated, each spin determined to outlast her opponent. Her heart raced, not just from the excitement of the battle, but from the exhilaration of doing something that felt so right.

Blader X and Robin watched from the sidelines, their earlier skepticism fading as they saw the fire in Multi's eyes. "Okay," Robin admitted, "she's actually... kind of crushing it."

"Let's see if she can finish it," Blader X said, his gaze fixed on the spinning Beyblades.

With a burst of speed, Multi's Beyblade made its final move, colliding with Ryo's in a dazzling explosion of sparks. In an instant, her Beyblade landed in the center of the arena, victorious.

"Yes!" Multi shouted, pumping her fist into the air. "I did it! Like Ash, I am a champion!"

Ryo, panting and stunned, lowered his Beyblade. "Alright, alright. You've got some serious moves, Ketchum. I mean... Nana-iro. But I won't let you get away with this next time!"

Blader X clapped slowly. "Well, well. Looks like someone really has found their groove."

Robin chuckled. "Yeah. Guess dressing like Ash isn't such a bad idea after all."

Multi grinned, her rainbow-streaked hair catching the light. "Next time, I'm going even further. Watch out, world—Multi Ketchum is just getting started."

As she walked off the stadium floor, a few spectators even cheered for her. Some had recognized her Ash-inspired outfit, while others were just impressed by her fierce, confident spirit. Robin and Blader X walked alongside her, still laughing.

"You know," Robin said thoughtfully, "you may have just started a new trend. Maybe we should all dress like our heroes in the next tournament."

Blader X shot him a look. "You can't be serious. That would be chaos."

Multi winked at them both. "Chaos is my middle name."

"Yeah, right after 'champion,'" Robin muttered, smiling. "But hey, if it makes you feel like a winner, I'm all for it."

Multi smiled, adjusting her headband with a wink. "Then let's see how the next match goes. I've got more championships to win—and more costumes to try on!"

Meanwhile, in an alternate reality…

A peaceful breeze drifted through the open fields of Pallet Town. Ash Ketchum, now the reigning world champion, sat outside his house, Pikachu perched comfortably on his shoulder. The sun was shining, the sky was clear, and everything was perfect for a relaxing day off.

That was until—

"ACHOO!"

Ash sneezed so hard that Pikachu nearly lost its balance.

"Chu?" Pikachu blinked in confusion, tilting its head at its trainer.

Ash rubbed his nose, frowning. "Weird… I just got the strangest feeling, like someone was… I dunno, dressing up as me somewhere out in the multiverse?"

Pikachu gave him a skeptical look.

"Yeah, yeah, I know it sounds crazy," Ash admitted, leaning back on his hands. "But think about it! What if there's some blader, or racer, or hero out there who saw me become world champion and went, 'Hey, I wanna dress up like that guy'?"

Pikachu rolled its eyes playfully. "Pika-pi~"

"Hey, don't 'Pika-pi' me like I'm imagining things!" Ash laughed. "I bet somewhere, somehow, there's a whole different world where someone's running around wearing my jacket and cap—battling in a completely different way!"
