One Piece: Peerless In Two Worlds

Finishing his training for the evening, Lee caught some sea kings and ate them using life return for his muscles and injuries. Sighing in satisfaction, Lee used a moonwalk and arrived at the top of the mountain.

The top of the mountain had a throne and bones around the throne. Looking around, Lee didn't see anything until he saw an untouched chest. Walking towards the chest, he picked it up and opened it.

Inside was a fruit, "A devil fruit?"

The fruit was red with a demonic mask on its face that looked like it was a back. Taking a bite of the fruit, Lee felt an overwhelming sense of change as his body suddenly began to convulse.

His back slowly turned into the shape of a devil's face grinning. His eyes rolled into his head as he fell asleep, the fruit changing his body and genes. Feeling the cool breeze, he saw a crow near him so he glared at it.

The killing intent of Lee made the crow almost faint as it flew away. "What did that fruit do to me?"

Lee realized that his voice was a bit deeper than before and he seemed a bit taller. Sitting down, he meditated and looked at his body. It seems the fruit has changed him into a 12-year-old's body.

"What is this fruit..."

Walking towards a tree, he suddenly had a flash of memory, Yujiro Hanma, Baki Hanma, and Jack Hanma.

His demon back activated and he suddenly released a lot of killing intent. He finally understood what this fruit was, it turned him into a Hanma. Remembering the techniques of the Baki universe, he grew excited.

Imagining his body as water, he smacked the tree and a sonic boom made the forest shake. The tree, however, flew into the sea in pieces.

"The power of imagination...is amazing, haha!"

On a Navy Ship with a Dog Warhead in front of it, there was a burly man with black hair who was snacking on some crackers until he heard a faint sound. He looked in the direction of the sound and saw a piece of wood heading towards his ship.

Becoming confused, the burly man jumped into the sky and used a tempest kick to kick out a slash that turned the wood into wood chips.

Narrowing his eyes, he spread out his observation haki and noticed something in that direction. His gut told him, something was there, a man with a hat appeared behind the burly man with a sword sheathed on his side.

"Garp, why did you do that?"

Garp, chuckled, "Bogard, head towards that island, I have a good feeling in my gut."

Rolling his eyes, Bogard told the marines to head towards the island in the distance...

Adjusting to his strength and speed, Lee began to do pushups and imagined two vans on his back. "I knew it, haha!" There was an imaginary weight on his back, it was putting pressure on his back, making him sweat.

Ten pushups later, Garp landed on the island releasing his observation haki, surveying the area, and found nothing.

Bogard landed next to him and noticed the quiet forest, "Is there...something here?"

"Yes, something dangerous, haha!"

Lee, who was currently on the tallest tree, watched Garp and Bogard walk towards the mountain. "Hanma is truly the best genes, it can even hide me from haki."

Hiding his presence and haki is easy due to his genes and experience as a strong man who wants everything to be under his control so he desperately masters it. No shortcomings are his mindset, that is why Lee remembered so many techniques. 

He had counters for counters, and 100 counters is better than one. Following Garp, hiding everything, even his scent. "Come out!"

Lee was confused, "How did you find me?"

Garp smirked, "I didn't, you did."

Jumping down, Lee was annoyed he fell for such a simple trick. "Who are you and why are you here on my island."

Garp looked at Lee, he looked at least 12 and his physique was quite strong to be able to jump on the trees. "Was it you who attacked my ship?"

"Me?"

Bogard was equally confused, "Sir?"

Garp raised his hand and Bogard didn't say anything else, "A piece of wood came flying at my ship at quite a speed."

"Oh...I was using a move, my bad?"

"A move? Can you show me?" Garp smirked, "I am quite strong." Standing in a horse stance, he puffed out his chest.

Lee sighed and said, "You, to the right, cover your ears."

Bogard was confused, then he saw this wild man begin to fall on the ground weirdly. Garp was confused as well and was laughing internally a little bit. "Come on!"

Imagining himself as water, he punched and condensed armament haki on his fist as his fist broke the sound barrier. Garp's eyes widen as he realizes this move, broke the sound barrier. Releasing his haki to cover his chest, it became black.

In a second, the entire island became silent as a shockwave almost blew away Bogard. Garp skidded back 10 miles as his chest was steaming and was a bit red. He was sweating as he looked at the destruction of the punch.

Trees were broken and the ground was pushed out from where Lee hit Garp in the chest. Lee on the other hand was looking at his fist and looking sad, "I can't even penetrate Garp's defense, how pathetic."

Shaving in front of Lee, Garp smirked and held a thumbs up, "That was an amazing punch, but...wasn't haki overkill?"

Lee smirked, "You didn't use it first, not me, I never said I couldn't use it."

"You...brat, join the Marines," said Garp as he tried to hold Lee's head who dodged using observation haki. "You even have...haha, you are a monster!"

"Fine, but I just have one condition."

Garp smirked, "Name it."

Lee yawned, "I want to only reach Rear Admiral, that is all I aspire to be."

A vein popped up on Garp's head, "You brat, your talent is too good to be a Rear Admiral!" Garp tried to punch Lee's head with the Fist of Justice but he dodged it again and shaved to the ship.

"Come on Vice Admiral Garp, I am your new marine recruit, don't lose face to the others," said Lee who shaved away laughing.

"How did you even learn to shave?" Garp wondered as he shaved, Bogard on the other hand was on the ship tending his bleeding ears, he didn't cover his ears with haki so his ear drums got busted.

Reaching the ship first, Garp smirked, then he looked around and saw Lee on the top of the sail. "I win the race," said Lee who jumped down and controlled his landing.

"You...surprise me more and more, and you say you want to only be a Rear Admiral," said Garp shaking his head as he commanded them to head to Navy Headquarters. 

Sitting on his chair, Garp put his feet up and began to sip some sugar water with a lime in it. Wearing sunglasses, he watches Lee, who was doing two-finger pushups. "How the hell..." said Bogard cleaning his ears. 

"Brat, I almost forgot, what is your name!" yelled Garp.

Lee stopped training and smirked, "Lee."

"No last name?"

"No," said Lee who began to do one-finger pushups as he imagined two elephants on himself.

Two hours went by and during lunch on the ship, they were shocked at Lee's appetite. His big belly was full then suddenly it all went into his body and he kept eating. Everyone couldn't even eat one bite as Lee piled plates on plates.

Garp then kicked Lee out and ordered him to catch Sea Kings for eating that much. Grumbling, Lee walked toward the edge of the ship and sighed. Noticing a Sea King approaching near the boat.

"It is too far, I can't reach it, unless." Lee once tested if he would drown as he ate a devil fruit but he didn't, why? He can only speculate it was his cheat, Hanma genes can make you a top powerhouse in many verses. "I guess the Void read my mind and knew why I wanted Hanma genes."

Swimming in the ocean, he quickly caught up to the Sea King and punched it with a mach punch. Dragging the Sea King, he dropped it onto the boat. The marines who were practicing and cleaning were shocked at a huge Sea King in the sky.

"Are Sea King able to fly now?" said Garp confused as he was sipping some lemonade.

Lee then hardened his hand and made it as sharp as a knife, almost like his technique but less sharp. Chopping the good parts in multiple slashes, the bad parts were mach punched into the distance.

Smirking, Garp told the chefs to make Sea Kings into a feast. Everyone celebrated as they finally had someone capable like Vice Admiral Garp who could protect them. People wanted to chat with Lee, but he was too busy training imagining 10 boulders on each of his limbs.

Dinner time was fun since most marines had never eaten Sea Kings before, so it was a delicacy. They toasted to Lee, Lee at this moment was stuffing his face with Sea King soup and grilled Sea King.

Eating his fill, Lee decided to train more, he felt as if he could break through and unlock something. Garp, noticing Lee as he walked away, sighed and followed.

Watching as Lee began to work out like a madman, he saw the sweat and steam coming off his body. Garp then watched as Lee began to punch and kick the air as if he was fighting an opponent.

Lee at this moment was fighting The God Of Strength Li Yu from his past life who, through his only physique, became a god and was accepted into the Heavenly Sect as an elder's disciple.

Blocking, parrying, Lee was taking damage but he was recovering using the food. "What?! You can do this with return of life?!" Garp noticed that Lee seemed to be repeating a battle he once fought.

Garp used to do that to get his training pumped, he imagined fighting Sengoku or Roger or Whitebeard...even Rocks. Watching more and more, he was getting too shocked so he began to walk to his room and sleep.

Lee, who finished the sparring, fell on the deck asleep...
