Straw Hat Pirates With Rimuru

CH 1 :Rimuru In One Piece!!

The Thousand Sunny, sailing through the Grand Line.

---

The sun hung high in the sky, casting its warm glow over the Thousand Sunny as it sliced through the waves. Onboard, the Straw Hat Pirates were enjoying a rare moment of peace. Luffy, their captain, was lounging on the deck, a goofy grin plastered across his face as he stared up at the clouds. Little did they know, a surprising twist of fate was about to unfold.

Suddenly, a shimmering portal appeared in the air above the ship. It spiraled and glimmered like the surface of a pond disturbed by a breeze. Out of it emerged a figure that brought a mix of awe and confusion to the crew.

Rimuru Tempest, a being of unimaginable power, landed gracefully on the sunny deck. He was a small, blue, slime-like creature with bright, glimmering eyes that radiated a sense of calm and strength. The Straw Hats stared at him, their jaws dropping in disbelief.

"What the hell is that?" Zoro grumbled, adjusting his swords as he eyed the newcomer suspiciously.

"Don't be rude, Zoro!" Nami scolded, eyes wide with curiosity. "It's... cute?"

"Cute? It looks like a jelly!" Sanji interjected, leaning forward to catch a better look. "But a jelly that can't possibly be good for you."

Rimuru wobbled slightly, his form shifting and pulsating as he regarded the crew with a friendly smile. "Hello! I'm Rimuru Tempest. I seem to have... crossed over to a different world."

"Crossed over?" Luffy exclaimed, sitting up abruptly. "That sounds fun! Can you take us with you?"

"Luffy!" Nami shouted, exasperated. "We don't even know what he can do!"

"Yeah! What if he's dangerous?" Zoro added, crossing his arms.

Rimuru chuckled lightly, his eyes sparkling with mischief. "I promise I'm not dangerous. In fact, I can help you all. I'm a demon lord, you know? I can do a lot of things."

"Demon lord?" Franky chimed in, his mechanical eyes lighting up with interest. "That sounds awesome! Do you have any cool gadgets or weapons?"

"Well, not really weapons in the traditional sense," Rimuru replied, glancing around at the crew. "But I can absorb things and acquire their abilities. I can also create a variety of skills. For instance..." He paused, and in a flash, transformed into a perfect replica of Luffy.

The crew gasped collectively, their eyes wide as they took in the sight. Luffy's grin widened as he beamed at the copy of himself. "Whoa! That's amazing! You look just like me!"

"Isn't that a little weird?" Usopp asked, scratching his head. "Are you like a doppelganger or something?"

Rimuru, still in Luffy's form, laughed. "Not quite! I can take on the appearance of anyone I encounter. It's more like... a talent of mine."

"Talent? More like a party trick!" Zoro scoffed, though he couldn't help but be intrigued. "Can you fight?"

"Of course!" Rimuru replied, transforming back into his original form. "I may look small, but I can hold my own in a fight. In fact, I'd love to spar with you, Zoro!"

Zoro smirked, his competitive spirit ignited. "You think you can take me on? Alright, let's see what you've got!"

Before Zoro could draw his swords, Rimuru's form shifted again, this time transforming into a larger, muscular version of himself, resembling a powerful warrior. "How about this?"
