One Piece : Building Strongest Crew

A great news story broke out in the East Blue, one that could resonate throughout the Four Seas, the Grand Line, and even the New World!

The legendary pirate known as Golden Lion Shiki, who was once mentioned in the same breath as the Pirate King Gol D. Roger and "Whitebeard" Edward Newgate, has been captured by the Marines once again!

Twenty years ago, he became the only pirate in history to escape from Impel Down.

At this very moment, he is once again imprisoned!

But what nobody knows is that the ones who defeated this legendary pirate were not the Marines but a group of "rookies" who set sail less than a year ago—the Straw Hat Pirates!

...

Impel Down, Level 6: Eternal Hell.

"Where am I?"

Jack slowly opened his eyes, took in his surroundings, and realized that he was enclosed in a dimly lit cell, completely different from his own room.

Ssh...

As soon as he surveyed his surroundings, numerous fragments of memories flooded his mind.

They played like slides, piecing together scenes in Jack's mind.

Every memory was so vivid, as if he had experienced them himself.

Suddenly, he understood.

He had somehow crossed over into the world of One Piece and ended up as a prisoner in Impel Down!

The crucial point was that he was confined to the sixth level, alongside notorious and ferocious pirates like "Sand Crocodile" Sandersonia, Douglas Bullet, and others!

How on earth did this happen?

Since his earliest memories, he had spent sixteen years in this dark Impel Down.

His name or anything else didn't matter; the only certainty was that he was a D. carrier!

Jack D. Blackwood

This was probably the reason why he was here.

Damn! A real hellish start, huh?

How can I escape from here?

Am I going to spend my whole life here?

Jack wore a bitter expression on his face.

At that moment, two guards escorted a prisoner towards him.

With Golden hair that reached the ground, his legs replaced with two sharp blades, this prisoner was someone Jack recognized!

Golden Lion Shiki!!

However, Shiki's appearance differed somewhat from what Jack remembered. He exuded an extremely weathered aura, as if he could meet his end at any moment.

"You want me to be locked up with a little brat?" he sneered.

"What a joke!"

Though his aura was weak, his tone remained arrogant.

So arrogant? That's definitely Golden Lion!

Before Jack could even complain, a voice resounded in his mind.

[Ding]

[Host environment detected. Ability Download System activated.]

[Would you like to claim the Newcomer's Starter Pack?]

Upon hearing the notification, Jack immediately grew excited.

Did I receive a cheat code?

An ability download system?

It sounded pretty good, but how do I use it?

[Ding]

[System prompt: This is the Ability Download System.]

[Its function is to download others' abilities and make them your own.]

[Abilities include but are not limited to Haki, martial arts, Devil Fruit powers, swordsmanship, etc.]

As Jack was still pondering in his mind, the system immediately provided an explanation.

Download others' abilities onto myself?

That's so awesome!

And there are Devil Fruit powers too?

I just don't know if there are any curse effects.

As he heard the system's prompt, Jack's eyes lit up.

"System, how do I download abilities?"

With time running short, Jack quickly inquired within his mind.

[Ding]

[Host only needs to be within a three-meter range of the target to initiate the download.]

[During the download process,

the range cannot be exceeded, otherwise, it will be considered a failed attempt, progress will be reset, and one download opportunity will be consumed.]

[The required time for the download depends on the strength of the ability.]

[Prompt: There is only one download opportunity per day!]

[Prompt: The Newcomer's Starter Pack has not been used. Would you like to use it?]

"Ah, I see... Starter pack? Why wait? Let's use it now!"

Upon hearing the system's prompt, Jack immediately became eager.

[Ding]

[Reward obtained: Instant Download opportunity!]

Instant download?

With this reward, I should be able to ascend to the heavens!

Immediately, Jack utilized the system to scan for potential targets within his range.

['Golden Lion' Shiki]

[Fruit Power: Float-Float Fruit (Perfect)]

[Haki: Conqueror's Haki (Proficient), Armament Haki (Mastery), Observation Haki (Mastery)]

[Swordsmanship: Golden Lion's Dual Blades]

...

The system categorized the mastery level of abilities into five ranks: Proficient, Skilled, Mastery, Excellence, and Perfect.

Special personal techniques like Shiki's "Lion's Thousand Cuts" weren't graded.

A Perfect-level Float-Float Fruit?

No wonder he can use the ability to float in the air without much physical exertion!

And he can even control the buoyancy of seawater!

Conqueror's Haki?

Although it wasn't demonstrated in the movie, that doesn't mean Golden Lion didn't possess it. After all, being a legendary pirate mentioned in the same breath as Roger and Whitebeard, he must have had Conqueror's Haki.

However, his mastery of the three types of Haki is truly low!

To only be proficient in Conqueror's Haki, it's probably lower than the proficiency shown by Luffy and Ace when they fought.

And there's Armament Haki and Observation Haki, a decent level!

But upon further thought, with such powerful Devil Fruit abilities, he probably didn't focus much on Haki training.

Jack initially wanted to see the abilities of other notorious pirates imprisoned in Impel Down, but unfortunately, his range wasn't sufficient.

Thus, he once again turned his attention to Golden Lion.

"If that's the case, what other option do I have?"

"Download the Float-Float Fruit!"
