AN: There's really not enough Ben 10 and One Piece crossovers out there, at least compared to the likes of Fairy Tail and RWBY. Before anybody asks, this is no way connected to Ten Piece and that doesn't mean I'm quitting it either. This is obviously a different take since I'm using Ben 10,000 since he doesn't get used very much for obvious reasons and the fact that Ben ends up in the One Piece universe unintentionally due to the events of the Time War and the ongoing battle with Maltruant and Eon. I feel that adding villains who have given Ben 10K a hard time in the past balances things out. I hope you enjoy this story just as much as the other one.

The rogue Chronosapien Maltruant sought to create a universe of his own design with the modified Anihilaarg and Dwarf Star. He came to the time period of Ben 10,000 to steal these items so he could create a more deadly weapon. It was then that he fought Ben Tennyson the wielder of the Omnitrix who was now know as "the hero of heroes" as well as his allies. Ben fought with all his might, but Maltraunt was always one step ahead of him with his ability to manipulate time, halting it, slowing it down or speeding it up. By rapidly shifting through time, Maltruant appeared to be in multiple places at once. Eventually, Maltruant was able to defeat Ben by freezing him and his team in time. Eon suddenly appeared with a Time Beast and Maltruant got onto it and thanked Eon for his assistance, now preparing to head to the beginning of time itself to enact his plan. Not willing to let the two time travelers get away, Ben transformed into Clockwork and unfreezes time with his own chronokinesis and rushed at both Maltruant and Eon; just as the latter initiated a vortex behind them. The Chronosapien tackled his foes which led to the alien hero, time walker, and mastermind of the Time War to be sucked into the portal.

In an abrupt start, Ben jerked himself awake, heart hammering in his chest. His breath labored and face perspiring, Ben took several long minutes to collect his himself. His eyes drifted towards his arms, which then followed to touch his face, as if testing if it was truly real or not. When his hands met the unmistakable skin that was his face, he realized that he wasn't somehow dreaming; he was indeed alive, the Anihilaarg hadn't accidently set off or something.

Looking around, he noticed that he was covered by a white blanket, sitting on a full sized bed, positioned inside a small square-shaped brick walled room. Near him lay another bed in similar design, holding a single occupant. A young man with a small scar under his right eye, and wrapped in medical bandages that covered what Ben presumed were injuries. Another observation that Ben noticed was that the boy was stripped of any clothing, leaving him bare naked. It took Ben a moment to realize that he too was left nude and scarce of any clothing. To the hero's dismay and utter embarrassment, his trademark outfit was gone.

Ben was broken from his sullen mood; his hearing only now had picked up on the numerous hushed whispers off to his side. Turning in the direction of the sound, Ben was surprised to see a large collection of women peering through the opposite side of steel bars that separated them from Ben. Ben was momentarily at a loss for words, as his eyes took in the appearance of the females before him.

Some were of average height, while others were unnaturally tall and bulky for normal human females. They all wore a similar state of attire, that being tribal clothing and animal pelts that covered only their more private areas, leaving much of their skin bare. A few of them wore long white capes on their backs that reached to their lower back and ankles. Every one of them had live snakes of varying colors that coiled around their bodies from their necks, seemingly tamed or domesticated. They were an odd sight to be sure, but in comparison to the individuals Ben had met throughout his hero career, their appearance didn't faze him in the least.

Their whispered conversations ended abruptly at the sudden loud yawning originating from the young boy on the other bed near Ben. Ben saw the boy stifle another yawn and then scratch his untamed black hair with one hand, while the other rubbed his tired eyes. The conversation between the women picked up again, loud enough for Ben to hear some snippets of their conversation.

"They certainly had a long sleep."

"Did you hear the rumors? Apparently, the skinny one ate while asleep."

"So what do men eat anyway? Raw meat?"

"Such ruggedly unusual beasts…"

"Look at them! They have no chest at all!"

Still drowsy, the boy crawled out of the sheets, murmuring softly. "What's all that racket…?"

"AHH! IT SPOKE!" one of the women from the crowd shouted, finger pointed at the boy.

The young boy either ignored the women's presence or he simply hadn't noticed them. He shook his head left and right, confusion obviously displayed on his face. Again, he spoke to aloud to himself, voicing his thoughts. "Huh? Where am I? What was I doing again?" Suddenly, a rush of memories came flooding through the rubber boy's mind. He remembered his crew on Sabaody Archipelago, followed by the traumatic battle with the shichibukai, Bartholomew Kuma.

One of the women seemed to grow frustrated as she strained to hear what the young man was saying over her fellow females' chatter. "SSSHH! Everyone it's saying something, quiet." She chastised.

Ben watched as the boy murmured some more incoherent words to himself, before his eyes wandered around the room, as though in search of something. His eyes lit up when he seemingly had found what he was looking for. "Ahh! There it is!" To both Ben and the women's surprise, the lanky boy's arm stretched to impossible lengths, passing through the room's vertical bars and snatching an old straw hat from the head of an unsuspecting female before receding back to its normal length. More than a few of the women staggered back in surprise.

A female with neck length hair held back to the side by a hairpin began to furiously scribble something into a notepad before questioning the boy. "Hey, what's your name?" Her fellow females silently waited for the boy to reply, eager to hear him speak more.

The boy stared at them with a rather blank expression before replying. "Huh? I'm Luffy." Luffy's eyes drifted around in an almost distracted manner before he looked down and shouted with a start, "Ah, I'm naked!"

Ben blinked as the whole crowd of woman gave Luffy an incredulous look. Some were more vocal and called out the straw-hat boy on how dense he was. Luffy shivered, now conscious of the fact that he had no clothing. But oddly enough he didn't seem all that bothered by the fact that a large crowd of females were openly staring at his nude form with strangely rapt interest. The boy didn't even bother to hide his modesty, but rather continued to converse with the tribal females in a rather casual manner.

"It's cold. What happened to my clothes?"

The females seemed to ignore his question, as one of them; a blonde haired female with neck length hair, posed a question of her own. She crouched in front of the metal bars, pointing in the general direction of Luffy's lower region. "Um, before you put on clothes, what do you have inside those sacks between your legs?"

Luffy crossed his arms over his chest and looked back down at his package, eyebrows raised in confusion. "You dunno know what this is?" He looked at the group of tribal women only to find a mix of curious and befuddled expressions. "You people are weird. These are my family jewels!" Luffy exclaimed in an exasperated manner. How could these women not know what these were? It should have been obvious, even to one such as himself.

"Family…jewels?" The women repeated the word over and over, unknowing of its true meaning. A few in the back of the crowd craned over the blonde woman to get a better look at the apparent phenomenon that was Luffy's manhood. Ben meanwhile, just observed the strange situation, trying to make head or tails of everything and thinking that he may need five years worth of therapy after this. These women acted like they had never seen a male before in their life.

"What do you mean by "family jewels"? " The blonde, apparently known as Marguerite pressed.

Luffy put both hands on his waist, allowing the women to get a better look. "Well, they're jewels of course!" He proudly proclaimed without a hint of shame and a huge grin on his face. The women stared open mouthed at the prospect that objects before them were so valuable.

Marguerite was the first to get out of her shock. "Hey, can you take those family jewels off and show them to us?" she pleaded with such innocence. Her fellow females eagerly held the same sentiment and held their palms out expectantly.

Ben, at this point couldn't hold it in any longer and guffawed out loud at the spectacle before him. He laughed so hard that his stomach had started to hurt. Luffy, on the other hand, didn't think it so funny and denied them rather vehemently.

Marguerite and the other women looked somewhat disappointed but handed Luffy his clothes, nonetheless. "Here you go. Your old ones were tattered so we made new ones in the same shape." Luffy graciously took the offered clothes and thanked them for their generosity.

The other female with the hair pin ushered Ben over. Ben obliged and to his delight she had his green jacket plus the rest of his clothes. "We found you floating unconscious up the nearby river stream. Your clothes got all wet so we dried them for you."

"Ah, thanks. I was wondering where it had go…ne" Ben trailed off once he found that his trademark black shirt with a white stripe had been altered. Along the shoulder lines and across the waist were neatly woven flower petal patterns. Ben held his shirt with shaking hands as he sulked about the alterations done to them. Luffy wasn't doing much better as his clothes also had flowering patterns stitched into the fabric.

Marguerite smiled kindly at them, confusing their sullen expressions with one of pure joy. "I put some sexy flower-frills on them."

Luffy though, wasn't having any that. His sulking mood quickly turned furious as he slammed his hand against the metal wall and yelled in outrage. "AHH! QUIT SCREWING WITH ME! I'M A MAN, YOU KNOW!"

A tribal woman with dark black hair tied firmly in a long ponytail and strong cheekbones narrowed her sharp eyes before jumping backwards a good distance away from the prison bars. Her fellow females immediately followed, brandishing weapons in Ben and Luffy's direction. The snakes that were curled around their bodies had taken the shape of bows. It was clear to Ben that the woman with the ponytail and sharply defined cheeks was the apparent leader of the group; at least with the way she carried herself and took command.

"You see," the woman began, voice full of suspicion and contempt for the men she had her arrow trained on. "This is man's true nature; ferocious. No better than an enraged beast. You show them an act of kindness and in return they lash out in anger at you." Her fellow female warriors murmured unanimously in agreement, swayed by their leader's words.

"As I thought," she continued. "Our kind simply cannot coexist." Meanwhile, Ben watched the events unfold before him with a puzzled expression. The Omnitrix wielder was admittedly confused by the sudden turn of events. He'd presumed the tribal looking women to be rather nice, especially since they took him in and cleaned his clothes for him. Ben's inner musings blocked out most of the conversations taking place between Luffy and the Amazons but the long time hero managed to catch a few things such as the fact that he was currently on an island inhabited by only females and that this Hebihime-sama was its undisputed queen or ruler.

Before Ben could give his own input to perhaps diffuse the tense situation, the leader of the group, whose name was apparently Kikyou ordered her warriors to fire. Both Ben and Luffy jumped on instinct with Ben transforming into XLR8 in a green flash much to the utter shock of everyone present, having seen this man transform into some sort of creature. Both Luffy and XLR8 crashing through the stone ceiling, with the former narrowly avoiding the speeding rush of arrows that flooded into the cell, plowing easily through the steel bars that once held Ben and Luffy. Underneath his visor, Ben openly gawked at the amount of power that the Amazonian's arrows packed.

Now Ben wasn't by any means the most perceptive guy around, but even he was took note that the women's arrows contained far more force than any normal arrow should've contained. Ben could feel that a least a few of the women were somewhat reluctant to fight him as well. A fight between two begrudging participants never ended well.

XLR8 landed with a soft thud onto the tiled roof, just as Luffy did. The boy with the straw hat looked just as bewildered as Ben. "Why are you attacking us?!" XLR8 questioned the Amazons in his raspy voice, only to be forced to use his incredible speed to dodge more arrows that seared past his face. Luffy made use of his inhuman stretching ability to weave through oncoming arrows at impossible angles.

"Aphelandra!" Kikyou shouted, extracting another arrow from her pouch and lining for another shot.

"Right!" an abnormally tall woman cried as she leaped in front of both XLR8 and Luffy, arms stretched outwards and blocking their path. Caught by surprise, XLR8 and Luffy crashed face first into the Amazon's sizable chest, repelling them backwards off their feet. Both of them managed to regain their bearings, landing nimbly on the dirt floor.

Luffy looked amongst the group of Amazonian warriors until his eyes laid upon a specific one. Extending his arm out, the rubber boy ensnared the unsuspecting female around her chest and waist. Making certain that he'd gotten a good hold of the woman, Luffy once again leaped back onto the roof, just as he sidestepped a slash from a warrior's sword. Not knowing what to do, XLR8 simply followed the stretchable boy and the screaming girl held in his grip, being much faster than Luffy; but going just slow enough so that he could keep up. Together, the two men scaled the enormous rocky wall that encased the entire village in.

"Oh no! Margaret has been taken!" Aphelandra shrieked, immensely worried for her friend's safety.

Kikyou cursed under her breathe before administering orders to her warriors. "After them! We must capture them before Hebihime-sama returns!" That was enough motivation to jump start the band of warriors into action and begin their pursuit of the dreaded men.d

Once they'd made it to the apex of the steep wall, Luffy only spared a moments look at the nerve racking height that led to the jungle below, before the scared boy fearlessly jumped off the rocky cliff. The female Amazon screamed her lungs out, face etched in horror at what she anticipated to be her death. XLR8 hadn't even spared a shred of hesitation as he sped down the wall of the cliff with reckless abandon. The legendary hero let a grin crease his visage as he enjoyed the cool air of breeze wash across his form as he sped down towards the abyss of the jungle floor; curious as to where this strange turn of events would lead him next.

AN: So that's all for this chapter. In case you're all wondering, this version of Ben 10,000 is the one from the original series. Also, the premise is inspired by the last two episodes of Omniverse: The End of an Era and A New Dawn. Well, I'll see you next chapter, which coming out sooner than you think.
