One Piece: Three Fruits, Starting with the Dark-Dark Fruit

Garp slowly raised his head, staring at Luffy's eyes that flickered in and out, and forced a smile on his wrinkled face. He said,

"Luffy, this devil fruit really gave you extraordinary power, but are you controlling this devil fruit, or is it driving you? Judging from your current appearance, I'm afraid it's the latter."

Luffy's pupils shrank upon hearing this, and the color of his pupils completely turned black. He looked at Garp with a complicated expression and whispered,

"Grandpa, I..."

However, before he could finish his words, his pupils turned golden again. It was obviously a warm and bright color, but at this moment it gave people a cold feeling.

"Garp, you are a traitor to the D clan. You deserve this fate entirely from yourself!"

Garp stopped smiling. He knew that the person in front of him was not his grandson. He narrowed his eyes and said coldly,

"I have been a marine all my life. Although I have done some bad things, I have never thought of betraying my own justice. I never did in the past, and I will never do so now!"

Luffy was silent for a moment and said,

"It seems there is nothing more to say. Your persistence is worthy of praise, but it is used in the wrong place. It's a pity and sad!"

Garp sneered, and he held up his wounded body, head held high. At this moment, he seemed to have returned to the day when he first joined the navy.

"You are the pathetic one! You are occupying someone else's body but you are acting so compassionately. People like you are not qualified to point fingers at me!"

Luffy's face showed a hint of anger, and he said coldly,

"I don't want to waste any more time talking to a traitor like you. Now, you should pay the price for what you just did."

Garp disdainfully responded, and a dark color of armament slowly emerged on his fists.

The two looked at each other for a moment, then attacked at the same time, each punching the other in the face.

But Garp's body has now reached its limit, and even the armament color on his fist appears and disappears from time to time. The hit on Luffy's face in Nika form only caused him to slightly tilt his head.

But Garp himself was knocked flying backwards, falling to the ground and sliding for several meters.

The terrifying arm strength brought by the Nika form is not something that the current Garp can withstand even without the additional armament color.

The surrounding revolutionary soldiers immediately cheered when they saw this scene, with expressions of great satisfaction on their faces. After all, countless of their comrades had been killed or injured by Garp's iron fists.

But their cheers sounded unusually harsh to Luffy. He frowned, suppressed his inner restlessness, and walked towards Garp who was lying on the ground in front of him.

He had just taken a few steps when Garp stood up from the ground again. He wiped the blood off his face and assumed a fighting stance again.

Without waiting for Luffy to come over, he roared and rushed forward first.

Luffy gritted his teeth and shouted,

"Don't stand up again!!"

boom!

With a dull thud, Garp was knocked flying by Luffy's punch again. Luffy even used domineering power in this punch, but Garp still slowly got up from the ground like before, and rushed towards Luffy again.

Luffy was also completely infuriated by Garp's "stubborn" behavior. He simply stood there, waiting for Garp to rush over again and again, and was beaten back to where he was again and again.

After several rounds of back and forth, even Lindbergh couldn't stand it anymore and couldn't help but say,

"Luffy, he is your grandfather after all. The brothers have almost vented their anger, so let's give him a quick death!"

Luffy grabbed Garp's fist, and feeling Garp's weak fist, he said in a deep voice,

"It's over!"

Garp, who had been attacking intently from the beginning, suddenly raised his head and looked directly into Luffy's eyes. His sharp gaze like a knife made Luffy's heart, which was known as the "liberation drum", skip a beat.

Luffy came to his senses and thought to himself,

"It's just a flash of brilliance, a betrayer..."

Then, his face regained its indifference and he said calmly,

"Do you have anything else to say before we wrap up?"

In fact, he had wanted to get rid of Garp a long time ago, but the original will of this body had been hindering him.

But he had had enough of this kind of pulling, and at this moment his fist was filled with black and red domineering power, which was strong enough to smash Garp's heart into pieces.

Before, it would have been a matter of seconds for him to launch an attack of this magnitude, but the target happened to be Garp, who had a blood relationship with this body that was as deep as his bones and tendons, so he was unable to accumulate strength smoothly.

The muscles on Garp's face twitched a few times, revealing a smile that was uglier than crying, but this smile seemed inexplicably very kind to Luffy, and the domineering aura that he had worked so hard to gather in his fist almost dissipated.

He shook his head a few times, calmed himself down, raised his fist and pointed it at Karp's heart, and said,

"Nothing more to say? Then..."

Garp called out hoarsely,

"Luffy......"

Luffy's expression froze, and his pupils randomly turned into two colors, one black and one gold.

Garp slowly raised his other fist and said slowly,

"Although it's a little late, this is the only gift grandpa can give you now. Please accept it. Your father used to like this the most..."

Luffy asked in a daze.

"what?"

Garp's face suddenly flushed strangely, and the blood vessels on his arms began to break and wriggle like earthworms. A blood-stained fist suddenly enlarged in Luffy's pupils.

"The final... Iron Fist of Love!!!"

boom!

Garp's fist hit Luffy's face heavily. Although it was a punch without any domineering power, it directly blasted Luffy in the Nika form away, and his body shot into the Revolutionary Army behind like a bullet.

There was an uproar in the Revolutionary Army. Garp was still in the same posture as he was swinging his fist, standing there quietly like a stone sculpture.

After a while, Luffy, who had returned to normal, rushed out of the revolution like crazy, crying,

"grandfather!!!"

Apparently he had regained consciousness, but Cap could no longer respond to him.

As his consciousness was about to fall into complete darkness, Garp's mind echoed,

"It's finally over... Fortunately, at least I wasn't killed by my own grandson, but it was really embarrassing..."

"Long, Dad can finally see you again. I'm sorry, I didn't teach you well. Will you forgive me?"

"Sengoku, He, and Zephyr, I have to go first this time. I am so willful again! I am sorry for causing you so much trouble..."

"Jig, as a marine, am I qualified this time?"

"..."
