After discovering the remarkable ability known as Kill Intent Rebound from Shibai Ōtsutsuki.
Leon found a peculiar kind of joy.
After leaving the Naruto World, he continued his journey through countless worlds.
The fusion of the Doomsday genes had reached roughly the halfway point.
Once the fusion was complete, this leg of his journey would temporarily come to an end as well.
His next stop after the Naruto World was One Piece.
He arrived right in the middle of the Marineford War.
Amid the massive melee.
He suddenly appeared in the center of the crowd, swept a disdainful glance around, and said that everyone present was trash.
Then, swathes of hot-tempered pirates and Marines began dying one after another.
All because Leon had strengthened Kill Intent Rebound a little.
Back when it belonged to Shibai Ōtsutsuki.
Kill Intent Rebound could reflect another person's killing intent back at them as damage.
However, the ability only worked if he had made physical contact with the person who harbored killing intent toward him.
After Leon enhanced it slightly.
The ability became a permanent passive skill.
And it no longer required physical contact.
As long as someone harbored malice toward him, they would immediately receive real damage in return.
Thus, the moment Leon appeared and delivered his harsh words.
Half the people participating in the Marineford War were wiped out.
Anyone unaware of the truth might have thought he possessed the power to make his words reality. He called them trash, so they immediately turned into corpses and began polluting the environment.
But in reality, they had all been killed by Kill Intent Rebound.
Blackbeard, Squard, and the rest.
The instant they glared at him, they exploded into bloody pulp.
As for the other half who survived, most of them were severely injured.
