Genichi also wanted an answer to this question.
Although Monster Cells and Jewel of Four Souls have been assimilated into One Piece Universe, it wouldn't give the normal boost it would provide to most people considering Roger's strength, but there were so many things that could make him grow stronger, right?
The Devil Fruit that Roger ate was the Clank-Clank Fruit, a Devil Fruit that was supposed to be eaten by Bullet.
Genichi found this fruit some time ago, and through the Devil Fruit Encyclopedia that Makima obtained from the World Government, Genichi immediately knew that it was Clank-Clank Fruit at a glance.
At first, he wanted to let one of his characters to eat it, but he always felt that it was not suitable.
After all, Devil Fruit users were weak to sea water. He did not need to add another weakness to his character.
So he thought of handing it to Roger. After letting Roger eat it, Roger could give back more Emotion Points to himself anyway, so it was no big deal.
And now that Roger knew what Devil Fruit he ate, he swung his sword upwards, directly piercing a large hole through the ground, and then he jumped out of the hole.
"...Aatrox!"
The moment he came out, Roger was stunned.
Because the only one standing was Aatrox. The blood dyed the ground red, reflecting the dark clouds in the sky and the dead silence.
"Don't worry. They're not dead yet."
Seeing Roger come out, Aatrox was not surprised. He said calmly, "You humans sometimes need something to protect to become stronger, right? Then fight me with their lives on the line. If you lose, everyone will die."
"... Thank you." Roger actually thanked Aatrox
He clearly had killed many of Aatrox's companions!
In addition to thanking Aatrox for not killing everyone, Roger also thanked everyone for surviving from Aatrox's onslaught!
"Now, show me the new power you have obtained!"
Aatrox shouted as he released endless pressure.
"I will destroy you now that you've become stronger. I will pulverize the last hope of this world! Yes, that is my purpose. I want the people with hope die in despair. I won't even let the slightest glimmer of hope to exist in front of me!"
"I will show you."
Roger took a deep breath. Although he had just obtained Clank-Clank Fruit and hasn't awakened its true power yet, it only reduced the range of its power.
"This Devil Fruit is actually the most suitable one for me right now."
Roger looked at Aatrox, and then his hand began to move. His body actually slowly merged with his sword, Ace!
Moreover, the Jewel of Four Souls' Fragments in his other hand are also slowly integrated into his body!
Jewel of Four Souls' Fragments could directly integrate into an object, but Roger did not know how to do it.
He had picked up Jewel of Four Souls' Fragments, but it did not directly integrate into his body. However, some animals could easily fuse with it.
He did not know on what principle did it work for the time being, but now that he had the Clank-Clank Fruit, he did not have to worry about those things, because he could use his Devil Fruit's ability to directly integrate himself with Jewel of Four Souls' Fragments.
At the same time, there was also the Supreme Grade Blade, Ace, which was embedded with Jewel of Four Souls' Fragments. There were only a few things, and they were all in the range of his Clank-Clank Fruit.
And after merging himself with all of those, he entered his Monster Form. His body became dark, and he looked more like a monster than before. Because compared to his earlier transformation, his right hand was merged with his sword.
The rune on his forehead was shining, as if there was a piece of Jewel of Four Souls' Fragment in it. Now Roger only felt that the infinite power in his body was expanding. He had never felt this much power, and now this power was obeying him!
"Bring it on!"
Roger instantly disappeared from where he was. When he reappeared, he was already in front of Aatrox. It was pretty fast as even his past self would have difficulty to react to this speed.
However, the moment Roger appeared, Aatrox had already brandished that huge blade and collided with his blade. Immediately, a violent force shook the earth, and the entire island shook continuously!
Boom!
The entire sky directly exploded, and even the dark clouds that had accumulated an unknown amount of thickness spread into the distance, as if they were avoiding their battlefield!
"Not enough, not enough!"
"Is this all you got? Aren't you carrying the hope of those incompetent fools!" Aatrox mocked.
Roger gritted his teeth. At this moment, he had already used everything he got. Color of Arms Haki and Color of Supreme King Haki were imbued on his blade… No, on his body!
This was much easier than a simple blade. Just this change alone had already made him stronger, not to mention other factors.
However, even with so much strength, he was still unable to gain the upper hand against Aatrox!
"Godly Avoidance!"
Roger roared angrily. He swung his blade again. This blade directly crossed Aatrox's long sword and cut his huge body.
Let alone this body that was made of a pile of corpses, even a mountain would have been cut by this blade. However, after the blade pierced through Aatrox's body, it did not have the slightest effect.
"It doesn't hurt, it doesn't even itch! Gol D. Roger!"
At the same time, Aatrox charged toward Roger, and his big sword directly hit Roger's body. Roger was instantly sent flying, but Jewel of Four Souls' Fragments' power successfully repaired the destroyed internal organs in his body.
Monster!
Without the healing effect of Jewel of Four Souls' Fragments, the blow just now was enough to turn him into mincemeat!
Roger gritted his teeth, and after recovering, he retreated from that place.
He wanted to lure Aatrox away from that place. His battle with Aatrox would kill everyone!
"Divine Cut!"
As he retreated, Roger turned back and slashed again. The overwhelming force turned into a dark crescent moon as it was dished out!
