The Sharingan, proof of the Uchiha.
It should be clarified that Griffin wasn't a soul transmigrating into an infant's body in the pirate world.
As described on that panel, his body was created through the combination of Uchiha and the Snow Clan bloodlines from the ninja world—only the transmission point had malfunctioned.
Instead of appearing in the Land of Water in the ninja world, he ended up in this "world of water."
Fundamentally, he was a "person of the ninja world."
A human body from the ninja world consists of 130 trillion cells, roughly three times that of humans from his original world.
Yet such a body still paled in comparison to those in the pirate world.
There were plenty of kids who could fight wild beasts at just a few years old, remain unscathed after being hacked with blades or axes, and fully recover from severe injuries after just one meal...
There were too many similar examples. (Here, we selectively ignore the Supreme Grade Ladder.)
...
Chakra is the fusion of spiritual and physical energy, so it doesn't become unusable just because he changed worlds.
Fortunately, Bloodline Limits are powers latent within the body and can be used without systematic learning.
Ice Release and the Uchiha bloodline were essentially Griffin's cheat tools for this transmigration.
The Snow Clan was a Bloodline Limit family from the Land of Water, renowned for their Ice Release. The last known user was Haku, who forced Naruto to use Nine-Tailed Chakra.
Ice Release had a high development ceiling, integrating attack, control, defense, and even "aesthetics."
But compared to the Sharingan, Ice Release was slightly inferior.
A versatile Bloodline Limit embodying "insight, manipulation, and destruction," recognized throughout the ninja world as a terrifying combat force—an absolute power that overturned conventional shinobi!

Inside the prison cell.
Griffin stood in the shadows, his black short hair partially covering his brows and eyes, while his exposed pupils glowed crimson, with three tomoe spinning like blood-quenched blades.
"What... is that..."
Capone's voice trembled as he clearly sensed some invisible chains coiling around him.
That bone-piercing chill made his body shake violently.
Griffin didn't answer; only the red light of his Sharingan flickered as his Eye Power forcibly invaded Capone's consciousness.
From his childhood days playing with gunpowder and blowing up his cousin's outhouse, to taking the head of his first gang leader as an adult...
No information about the Stronghold Fruit was found.
Had he not encountered it yet, rather than hiding it without eating it?
The reason Griffin targeted Capone was precisely for this space-type Paramecia-type Fruit.
The function of this fruit needed no explanation—a storage bag the size of a castle. If this were in a fantasy-themed world, it would be enough to spark an auction house chase scenario.
Griffin had already eaten a Devil Fruit—a Zoan-type.
Though he couldn't consume another himself, he could feed it to a loyal subordinate.
...
Capone, who had just regained consciousness, rolled his eyes and fainted again. Having concluded the interrogation, Griffin stroked his chin in thought.
From the information he knew, Devil Fruits had the potential to choose their owners—a fate-like setting.
There were many such examples: Buggy, Blackbeard, Luffy...
Just like... when he had eaten that fruit.
So the Stronghold Fruit would also, at some point, be fatefully consumed by Capone...
Kill Capone and search for it then?
No, that would be an even more troublesome option.
Why did the Navy choose to imprison some dangerous ability-user criminals rather than execute them? Part of the reason was to prevent those dangerous fruits from circulating back into the world.
The known is always easier to deal with than the unknown.
Killing Capone and searching aimlessly was far less cost-effective than subduing him.
Griffin didn't have the patience like Blackbeard, who would watch Capone day and night just for one fruit.
——
Slap—slap—slap—
Capone was slapped awake, bleary-eyed.
"Where is this?! Damn Navy! Where have you taken me?!"
"Didn't Smoker get the call?! If you don't let me go, you'll be in big trouble!!"
Griffin had erased his memory of seeing the Sharingan.
In his plan, he needed to retain some of his strength for more covert operations, such as assassinating the Celestial Dragons.
Griffin waited until Capone had calmed down before speaking slowly.
"Finished shouting? Can we talk now?"
Capone's face darkened: "I wanted to talk with you back then, but you attacked without warning!"
Griffin shook his head: "That wasn't the right time."
"Capone, I need you to face reality so we can have a productive negotiation."
"Smoker did receive the call, but do you know what that person said?"
"If I kill you, the only punishment Smoker and I would face is a temporary halt in promotions—nothing more."
"If you dare kill me, you and your subordinates will all die, every last one of you!"
...
...
"First, status. Second..."
Griffin casually crossed his legs and said calmly, "What gangs believe in is speaking with fists."
"In terms of strength, you're no match for me either, right?"
"To put it crudely... Capone, you only get to eat because we, the Navy, allow it."
"You're not even a house dog—you're just a stray we occasionally throw scraps to."
...
"Bastard! What did you say?!"
Griffin raised his hand, and the simple gesture made Capone quiet down.
He glared darkly at Griffin and hissed, "Kid, your negotiation skills are terrible. Are you trying to lower my value to raise your price?"
"My arms business—the Navy is its biggest customer!"
"Kill me, and you think you'll only face a temporary promotion freeze? If you damage the organization's interests, a brat like you will never climb higher!"
Griffin smiled faintly: "You are useful, but you're not irreplaceable."
"I could easily kill you and groom another arms dealer. I've seen your ammunition—it's not hard to replicate."
"What the higher-ups care about isn't you, but the supply channel. I can restore that."
"I'm not like Smoker, some black-and-white righteous type. People like you are necessary in my view."
...
Capone's expression grew increasingly grim. He opened his mouth to retort but didn't know what to say.
Only parties of equal strength can call it a negotiation.
This brat had hit a sore spot, and most importantly...
He had lost.
What you can't gain on the battlefield, you'll never get at the negotiation table.
Capone took a deep breath and grinned.
"You're right!"
"But!"
"Unlike you Navy dogs serving the World Government! I will never submit!"
"I will never yield—that's my way of survival!!"
——
"Who said anything about making you yield?"
Griffin looked at the suddenly impassioned Capone as if he were an idiot.
He held up three fingers.
"I won't interfere with your arms business from now on, provided it doesn't involve civilians."
"I know the rules. We split the profits 70-30."
"I take 70%, you get 30%. Understood?"
