Transmigrated Into One Piece

Lucas opened his eyes to the sound of screams and the chaos of a town under siege. As his senses returned, he became more aware of his surroundings. Grabbing his head to soothe a slight headache, he noticed people running away from the direction he was facing. Some bumped into him, shouting, "Hey, hey! Don't just stand there, run!" But Lucas couldn't hear them clearly until wham—he was struck down by a large blunt object.

"Hehe, thought you could run away," a voice sneered as Lucas was tied up and taken captive.

"Ho. I remember now. My name's Lucas, and I died before. And now..." he gasped, memories flooding back. He recalled how he had died, hit by a truck on his way home from college. Lucas had been an engineering student at a TVET college, and as he walked home, truck-kun appeared out of nowhere and hit him. He then woke up in a strange, tranquil blue place where he found a faceless man wearing a three-piece suit.

"The roulette is offline, yet they're still sending people my way," the man sighed stressfully. "Then I'll improvise in my own way," he suddenly smiled.

Lucas was perplexed by the man's sudden smile. "Greetings. You can refer to me as The Manager. Long story short, you are among the lucky few who died and are given a chance to go to another world," the Manager explained.

"Oh, like isekai and transmigration stories," Lucas replied.

"Good, we'll go with that. Now then, the method I usually use is currently under maintenance. So I'll be using a different method. As the first person, how about I allow you to choose the abilities you want to carry with you? But first, select a world from this box," the Manager said as a light in the shape of a box lit up next to Lucas. A black box appeared.

"Just stick your hand inside and select a cube," the Manager instructed. Lucas did so, rummaging until he pulled out a blue, white, and black cube.

"Haa. An interesting choice. You'll be sent to the One Piece verse and by method of transmigration, no less—a rare method we use here," the Manager said, seeing the cube Lucas pulled out. "Okay then, your abilities," the Manager said, centering his faceless face on Lucas.

"Hmmm. I mean, are there limits..." Lucas asked.

"Oh. Good point. Then how about the good old three requests?" the Manager suggested.

"It's 'wishes,' but I'm not correcting that. I could've had unlimited requests here," Lucas thought to himself. "Okay then. I request to have the power of the Omnitrix, to be able to transform into all the aliens Ben could transform into in all Ben 10 shows, but without relying on a link to Primus or the Omnitrix, and having the battle readiness like the function of the complete Omnitrix in Omniverse," he said.

"And for the second request, I want the ability of the function of Ultimate Ben and Omniverse Ben 10k, fusing aliens at will and being able to maintain my form but wielding the abilities of the aliens I want," he added as the Manager nodded.

"Well, don't you seem to have it figured out," the Manager responded.

"So what if I'm an otaku who loves Ben 10," Lucas defended himself. "For my last request, I want additional transformations: Titan God from Astral Pet Store, Ainz Ooal Gown, a high elf from Magician From The Past, Atomic Samurai, a destroyer god, Plastic Man, Hyperion, and the Sentry. With Atomic Samurai, I want to transform into a samurai at his skill level, as well as the destroyer god thing, and to have the reboot Omnitrix with a purple color and having all Omnitrix features as the others. I'm interested in the specialized armor feature," he added as his last request. "If they were wishes, they would've been lesser," he thought.

"Okay then, let's wrap things up, shall we?" the Manager said. "You arrive around the beginning of the story. And you can find the Omnitrix in your dimension storage in your Titan God transformation," the Manager said as he waved his hand, making Lucas's body light up as he vanished, leading him to his current moment.

Lucas recalled everything, his eyes shimmering with a purple hue. "Fufufu, I've arrived in the One Piece world," he said with a grin.

"What's wrong with him?" a pirate asked his fellow mate.

"Don't know, I just gave him a slight tap to the head and carried him here," the other replied.

"Maybe I hit him too much," he added, dropping Lucas off where the other captives were.

"Listen up! All of you are now our prisoners. Pledge your allegiance to us, the Sparrow Pirates, or die!" the pirate declared.

"Sparrow Pirates? Never heard of them. And I'm already ticked off that the first thing that happens to me after arriving here is you guys knocking me out like that," Lucas said as he stood up, catching the eye of the captain sitting on a makeshift throne among the rubble of the town.

"Although I'm planning to be a pirate myself, I still find it unacceptable what you did to this place," he added, his voice filled with disdain.

"Hahaha, and you claim to want to become a pirate with that attitude, boy?" the captain mocked. "Only a fool..."

The captain's words were cut off as Lucas punched him in the face, contorting it. "It's rude to laugh at someone's dreams," Lucas said, his appearance slightly changing as he gained more muscle and a few centimeters in height.

"Captain!" the other pirates cried. "You'll pay for that!"

Lucas's body returned to normal, his clothes now a bit stretched. "So that's what it felt like to be the Sentry," he said, gauging his arms and noting the difference in strength. Although his appearance didn't change much, he had transformed into the Sentry as a test of his powers. His skin color remained ebony, and his hair didn't turn long and golden, but he had become the Sentry.

"I guess when I wear the Omnitrix, I'll also have access to the nanomachines to make clothes for my transformations," he muttered.

"Well then," Lucas's eyes still glowing purple, a symbol of his powers being activated, "how about a classic?" he said as the pirates attacked him. Their swords melted as they touched him, for Lucas had turned into Wildvine.

"Wha... Hu... Monster!" they screamed. The townspeople freaked out as well. Lucas swiftly transitioned between Heatblast and Wildvine, using his hands to stretch and whip the pirates.

"He must have eaten a Devil Fruit," another pirate said, but that didn't change a thing. Lucas overpowered the Sparrow Pirates.

"Good, now that that's over..." Lucas said with the pirates now tied up. He saw the villagers giving him a blank stare. "What's with the... I'm naked, aren't I?" he realized, noting that he wasn't currently carrying the Omnitrix, so he didn't have access to the nanomachines that would tailor his clothes. He quickly transformed into the elf and cast a memory spell to erase today's events. He then went on to the pirates' ship, taking it for himself.

Lucas accessed his pocket dimension using space magic and took out the Omnitrix, putting it on. It resembled the Alien Force recalibrated version but with a purple color instead of green. "Omnitrix linked to host," the Omnitrix turned on. It wasn't linked to Primus since it didn't exist, but instead linked to Lucas himself, with him functioning as Primus in a way.

"Does this mean you can still gather DNA samples for me?" Lucas asked.

"Yes, all functions are available," the watch responded.

Lucas smiled a little, wondering if people with Devil Fruit powers were regarded as a different species, kind of like how there are two variations of Upchuck. "They're cool and all, but it's not like I need them," he said as he rummaged through the ship, wearing clothes that fitted him.

"Ok... How do I operate this thing? I could just fly, but I don't even know where I'd be going," he said as he went out of the ship. The Sparrow Pirates' ship looked like it could carry a hundred men.

"Right. I'll just use a spell to make the ship move on its own! Right while I'm on it. I'll also engraved a rune on myself so I can stumoch being a pirate" Lucas said claiming the Sparrow Pirate's ship as his own and readying himself for when he might have to kill people.
