Omni-Piece: Race to the One-Piece!


I am working on a second Ben 10/One Piece crossover as I work on the Oneshot with what happens without Ben in the crew.

I will work on this and other projects in my spare time and keep you all updated!

Anything with '¬¬' will be bounties.


Chapter 3: Unstoppable!


Holding his hat on top of his head Luffy turned to Zoro who stood on the forefront of the water train: The RocketMan, they stared upwards at the massive wall of water that was heading towards them.

"What's the number up to now? Luffy asks twisting the kinks out of his shoulders; Zoro drew one of his swords and gazed back at Luffy. Who was currently bending down onto his knees; he seemed chipper, more like his usual self.

"216." Zoro calmly states his sword's tip pointing at the wave that cannonballs couldn't harm. Luffy turns his gaze, thinks for a second, and then huffs... he then stands bringing one of his fists upwards to the wall of water.

"Too long.. round it up?" Luffy asks turning back to Zoro, who nods; their energies link and with a twin shout... they send a wave of energy at the wall of water, time seems to come to a crawl as their shout of...


"Gum-Gum 300 Caliber Cannon"


Sends the water back into the recent calm waves as time resumes, the storm being left behind as their ride speeds towards danger and their missing crewmate.

"YOU GUYS ARE INSANE!" multiple people shout out, some from Luffy's crew such as Nami and Chopper!

One group currently voicing their concern were the 'Franky's Family' who had hitched a ride with Luffy, after he told them under duress! That as soon as he saved Robin, he'd knock their boss's teeth out... that was until he realised his fury could be used to gain a temporary alliance... well he would have eventually thought of that... they told him all about Franky trying to save the Merry with Usopp. That changed Luffy's mood a little...

The other group were Ice-pop's crew of shipwrights who wanted the piece of their former allies turned traitors!

The last three were some lady called Kokoro who was currently laughing her ass off whilst drinking as much as Zoro could... her granddaughter Chimney and her pet cat(?) Gonbe; who was currently being crushed by Chimney's arms.


Enies Lobby was on fire.

The Marines were relentless in their assault. Cannon fire, smoke, and shouts filled the air, but the Straw Hats—unbroken—continued to charge forward. Luffy's face was grim, his eyes set firmly on the goal: Robin.

The shipwrights, Franky, and even Zoro and Sanji had no time to rest. There was only one goal—get Robin back.

But as Luffy fought his way through the chaos, his hand brushed his straw hat. He reached inside and pulled out the Vivre Card—His Vivre Card. The one that had brought hope when everything seemed lost.

The card was glowing brighter than ever before. Luffy held it tightly, gazing at the name written on its surface, the name that should not have been there:

Ben Tennyson.

And then… the Vivre Card vanished.

Luffy's heart skipped a beat. His eyes widened. "He's here." Luffy whispered, his pulse racing as something big was happening.

The air seemed to still for a moment. Even the rumbling explosions and gunfire quieted, as if the world was holding its breath.


Robin and Luffy stood together, fighting side by side, as more Marines surrounded them. The massive walls of Enies Lobby loomed, and the Buster Call fleets were closing in. It felt like the end for the crew, but Robin—her smile weary yet relieved—was now safe.

But in the midst of the chaos, something else was shifting—the sky itself seemed to ripple.

Luffy looked up, eyes narrowing.

In an instant, a flash of green tore through the clouds. A crack of energy split the sky, splitting apart the storm clouds as if some otherworldly force was coming to reclaim what was lost.

And then—a giant shadow fell over Enies Lobby.

From the sky came a voice, dulled over the screams of Marines panicking and a shocked scream from one of the traitors who had been holding Robin. Their gazes were fixed upward, and there he was...

The Marines froze in disbelief. Spandam, in a panic, shouted orders, but even his voice seemed drowned out by the immense presence now descending upon them.

Then again, the voice said the words that began a laugh from Luffy—not his usual SHISHISHISH laugh, but one filled with tears and pure relief.


"DID YOU GUYS MISS ME?!" The giant being's voice boomed, sending a calming wave of reassurance through the Straw Hats as they felt the weight of the situation shift in their favor.

Luffy's eyes widened with disbelief as a rush of joy flooded him. "BEN!" The words slipped from his mouth as though he couldn't quite believe it. And then, in unison, the rest of the Straw Hat crew echoed his astonishment: "BEN?!"

Each of them stared up in awe, their hearts lifting as they saw the towering figure above them. His green skin shimmered, his massive frame blocking out the sun, but it wasn't just his size that amazed them—it was the fact that their ally, Ben, was back, stronger than ever.

"CALL ME WAY BIG!" the new figure says setting the Merry down into the water below; Luffy and the crew didn't even realise this giant; this WAY BIG had their ship in his hand.

Luffy stood frozen for a moment before a massive grin broke out on his face, his eyes watering with relief.

"I knew you'd come back!"

Franky, who had been next to Luffy, blinked in shock, then threw his hands up.

"You know this giant?"

Nami, Chopper, Sanji, and the rest of the crew couldn't help but laugh, even as they stood in awe of Ben's new form.

Way Big's enormous hands returned up crossed over his chest. His voice, deep and resonant, rumbled as he spoke.

"Well, it's good to be back!"

The Straw Hats, reinvigorated by their friend's return, rallied together. It was time to finish what they started.


In a blink, the towering figure was gone, replaced by Ben standing tall and calm, his Merged-Model Omnitrix glowing on his wrist. His eyes flickered with the faintest trace of Haki, and a small, confident smile tugged at his lips.

Luffy's eyes widened in shock and joy, his Straw Hat slipping from his head as he rushed forward.

"BEN?!" Luffy shouted, his voice cracking with excitement. His fists shot into the air in pure joy.

Ben gave him a relaxed grin, raising a hand in a casual wave.

"Hey, Luffy. Long time no see," Ben said, his voice calm but carrying the weight of the moment.

Luffy couldn't hold back, laughing as he ran up to Ben and delivered a playful punch on his back. Ben turns giving Luffy a playful punch also; sending the Straw Hat teen on his back.

Ben chuckled, shaking his head with a grin. "You really did believe that, huh?"

Meanwhile, the Marines were frozen, their mouths agape. They had all heard the rumours—Ben Tennyson had died at the hands of Garp. They'd seen the news coos and heard the whispers. But seeing him here, alive and well, left them dumbfounded.

Spandam, panic rising in his voice, shouted orders in desperation.

"T-That's impossible! Garp killed him! We saw it in the papers! The news coos said he was dead!" Spandam stammered.

Ben turned his gaze toward him, a smirk creeping onto his face. The faint flicker of Haki surrounded his hands.

"Seems the news coos got it wrong," Ben said with a cool tone, his eyes narrowing slightly. "I'm not dead. But you're about to be."

Luffy punches his fist into the air with a leap and he stands shoulder to shoulder with Ben, completely ignoring the chaos around him.

"Let's go, Ben!" Luffy yelled, his voice full of excitement.

With that, the battle resumed, but this time with Ben back in action, ready to stand with his crew and take on anyone foolish enough to stand in their way.


"You—!" Spandam shouted, his voice wavering. "You're supposed to be dead! DIE!"

With shaky hands, Spandam fired. The bullet sped toward Ben, but before it could even come close, a sudden, calm movement stopped it in its tracks.

Ben's eyes flickered with a brief moment of concentration. His hand raised, the black energy of Haki enveloping it like a shield. The bullet hit the invisible barrier of armament Haki and was completely deflected, bouncing harmlessly to the ground.

The Straw Hats watched in awe as Ben, without breaking a sweat, looked at Spandam with an almost bored expression.

Spandam's face turned pale. "What... What is this?!"

Ben raised an eyebrow. "I don't think you're in a position to be shooting people."

Luffy, who had been watching in excitement, burst out laughing, slapping his knee. "I knew it!"

Spandam stammered, his hand shaking even more as he tried to pull the trigger again, but Ben was already taking a step forward. The moment he moved, a chill seemed to fill the air around him, the faint flicker of Haki still flowing around his hands.

"Last warning," Ben said, his tone calm but deadly serious. "Put the gun down before I decide to take action. You wouldn't want to test me further."

Spandam swallowed hard, his fingers twitching as if he still wanted to fight, but the sheer presence of Ben's power kept him rooted to the spot, his bravado crumbling. The Marines around him, who had also been watching the spectacle, could only stare, dumbfounded.

One of the soldiers next to Spandam, clearly panicked, grabbed his arm and pulled him back. "Sir! We can't fight him! Not with that power!"

Spandam, however, wasn't ready to give up just yet. His face twisted with a mixture of fury and fear. "Fine! Get back, you idiot!" he screamed, before turning to the rest of his men. "Don't just stand there! Get him!"

But it was clear: Ben was far beyond their reach.


The fires of Enies Lobby burned hot. The Straw Hats regrouped, the Marines too shaken by Ben's return to regroup. The Buster Call fleet had taken heavy damage—thanks to Way Big.

And then, like shadows cutting through the smoke, they arrived.

From the rooftops, five cloaked figures stepped forward. Cold eyes, blank expressions.

CP9.

Lucci, Kaku, Kalifa, Jabra, Blueno.

They gazed over the battlefield, assessing it like it was just another Tuesday.

Kaku, bored, glanced at the wreckage. "Took them long enough to break this place. I was starting to think they'd never reach the island."

Kalifa, sighing while checking her glasses: "Can we just wrap this up already? This place is a disaster."

Jabra cracked his neck lazily. "Heard Straw Hat got stronger. Hope he's more fun than last time."

Blueno, voice flat: "Robin has been taken... Our mission is manageable... return her.."

Then, Lucci spoke. Calm, certain. "We take her back. Eliminate the others. Simple."

But as they stepped forward—

They saw him.

Ben. Calm. Standing tall. The black energy of Haki pulsed faintly from his hands.

Luffy stood beside him. Robin behind them. The rest of the Straw Hats ready.

And Lucci paused.

Just for a second.

Kaku's eyes narrowed. "…That's not a Straw Hat."

Jabra scoffed. "Doesn't matter."


Ben looked up, smiling faintly. "Wow. You guys look strong... but I'm stronger!"

Luffy cracked his knuckles. "Hope they're ready to lose."

Robin said nothing. But her eyes were fixed on Lucci—calm, composed. Unafraid.

And for the first time…

CP9 wasn't hunting.

They were the ones being hunted.
