Animeverse Slayer!

Leo glared at Pedro for several seconds. After a while he sighed and shook his head.

"Go then. See it to the end. I'll take care of this. Also, leave that jacket here, I don't want you getting any more suicidal thoughts later."

Pedro took off the jacket and threw it away.

"Thank you."

Leo turned his head away. He was still angry. He needed to vent this anger somewhere.

His eyes focused on Big Mom in the distance. She was already up on her feet, and she had a small wound on her shoulder.

Pedro took a deep breath and jumped on the Sunny. He knew his friend's true ability, he wasn't worried something might happen to him.

When he got on the ship he saw Luffy confronting Katakuri. He wanted to help but Luffy stopped.

"He is mine!"

Saying that he rushed to Katakuri.

Katakuri was slightly distracted when he saw Leo. Even with his extreme kenbunshoku haki he could only see a couple of seconds into the future.

When he was distracted Luffy grabbed him and rushed into one of the mirrors. They smoothly went through the mirror and disappeared.

Brooke and Chopper managed to capture the one manipulating the mirrors, Brulee.

"We need to set sail, now!"

"What about him?"

Nami asked back.

Before Pedro could reply another voice replied.

"You guys staying here would only make things worse."

Who?!

Brooke and Chopper immediately got into a battle stance.

Pedro saw who it was and said, "Flare, only you came?"

Flare nodded, "There is some trouble back home, the rest are staying back to take care of it."

Brooke asked, "You know him?"

Pedro said, "It's alright. He is a friend."

Nami looked at Flare for several seconds before raising the sails. The sail caught the wind and the Sunny started to move.

Since Leo destroyed a part of the fleet surrounding them when he arrived they had no problem getting out of the encirclement.

Back on the island.

Leo narrowed his eyes. Ripples spread through the air as his domain expanded to it's limit.

Big Mom was like an insane beast. Fire and lighting surrounded her as she walked.

Leo took a step forward and reached her in an instant. His black blade gleamed with a shade of deep red at it's edge as he swung it down.

Even though Big Mom was in a state of madness, she was still a Yonko.

She raised her sword and blocked it.

The moment their swords met the air cracked. The sky turned dark and lightning flashed. Haoshoku haki exploded from their bodies and spread out.

Big Mom grunted. She took a step back and put more strength into her sword.

Prometheus floated behind her and merged with her hair. While Zeus increased in size and rained down lightning.

Sword rays condensed and swirled around Leo. It sliced apart the anything that came near him.

Big Mom howled.

Tendrils of flames rose from her hair and shot at Leo.

Leo pulled back his sword and twisted his body. The flaming hair missed him. However it turned back as if it were alive, trying to bind him.

Leo swiped his sword. The sword rays surrounding him condensed on his blade.

The flaming hair was slashed apart.

Big Mom was going crazy. Her haoshoku haki was constantly being released. Lightning and flames covered her entire body.

A sharp look flashed in Leo's eyes. He sheathed his sword and took a drawing stance.

Silent wind!

Leo disappeared from Big Mom's sight and from her kenbunshoku haki. He seems to have merged with the wind.

Slash!

A split second later he appeared before Big Mom. His sword hummed as it slashed at her throat.

Big Mom howled. Her throat was instantly covered with busoshoku haki.

Diinngg!!!

Leo's sword struck her throat, producing sparks.

Hmph!

Spurt!

Big Mom's busoshoku haki was slowly sliced through. Blood seeped out from her throat.

Aahhh!!!

Already in madness Big Mom roared when she saw her blood. Flames and lightning erupted with her at it's center.

Even with his domain and sword rays Leo had to take a step back.

The redness in Big Mom's eyes intensified. Right now she was fueled by her emotions. She was running wild with a single purpose, to get what she was craving for.

Leo raised his sword and attacked. He used Soru and Geppo in a perfect combination as he flashed around Big Mom.

He slowly chipped away the flame and lightning armour around her.

As he was fighting Big Mom, her subordinates had assembled and formed an army. Leading them were the officers. They had surrounded Leo and Big Mom.

A cold light flickered in his blue eyes.

He stepped through the sky using Geppo. Looking down he saw Big Mom staring at him, she still hadn't woken up from her crazy state.

Leo pointed his sword to the sky. His sword domain started flicker. Dense collection of sword rays started to condense in the sky.

1, 2,4... 10... 100... 1000... 100000...

Sword rays filled the sky and covered the sun like a blanket. However it didn't stop. Crazy amount of spirit erupted from Leo. His 'Breath' was furiously circulating through his body, providing him with strength.

The sky full of sword rays trembled. In an instant they quadrupled in number.

Leo's eyes flashed with intense murderous light.

The sword rays started to move. The closest ones merged to form an even stronger sword ray. This continued till the every sword ray merged four times.

Each merger refined the appearance of the sword rays. The body of energy filled with Leo's sword will was refined. It's form became clearer.

A few seconds later the merging was complete.

Big Mom pirates went pale as they watched the sky. Their weapons fell out of their hands and onto to the ground with a ding.

"Im-Impossible...

"How can we fight against that?...

Their eyes were filled with despair.

The sky was still blanked by sword rays. However the sword rays had completely changed. They were now shaped like swords!

A sky full of exquisite swords!

Just looking at it was enough to pull out the horror in one's heart.

Leo stared calmly at Big Mom and said, "A Yonko. The same title as Whitebeard."

"However, looking at you now, you are nothing more than a mindless beast. To sit on the same throne as he used to...

"You.Don't.Qualify!!"

His voice turned colder. Haoshoku haki exploded out of his body. The swords hanging above the island resonated with his haoshoku and hummed.

Leo sliced his sword through the air. The innumerable sword hanging above the sky fell down like rain.

Merciful Rain!!
