Animeverse Slayer!

Leo's ship was sailing towards an island in the distance. As they got close Leo's spiritual sense picked up an intense battle.

"Let's go Shinobu."

He jumped up into the air and drew a beeline towards the island. Shinobu used Geppo and followed closely.

Mace realised something was wrong and shouted at the crew to pick up speed.

...

On the island.

The battle between the lion headed man and the tall woman was still intense. The small town bore the brunt of their battle.

Buildings were torn down and corpse lay scattered throughout the area. However they gave no mind to it and continued.

The lion headed man roared and punched at the tall woman. His large fist clad in busoshoku haki tore through the air.

Armed!

The tall woman responded. Haki was attached to her sword as she jabbed her sword. The sword whistled as it pierced through the air.

The fist and sword met. The shockwave forced away everything near them. Both of them retreated and stared at each other for a moment.

Just as they were about to attack again their kenbunshoku haki picked up someone rushing in their direction with incredible speed.

Boom!

Before they could react someone landed right between them. The next second a tremendous force bore down on them and blasted them away.

They crashed through several buildings and left a long trail of dust and rubble before slowing down.

Damn!

He turned his eyes and focused on the ones who caused this. A powerful will erupted from him and pressed down on the two of them.

Haoshoku Haki!

Argh!

The lion headed man and the tall woman grunted. Their faces went pale, they raised their head and looked at the owner of this powerful will and was stunned.

A man wearing white shirt and black pants stood before them. He wore a navy coat of justice.

A marine!?

They were stunned to see a marine having the Colour of a Supreme King.

"Give up and surrender or... die!"

The lion headed man roared and shot towards Leo.

"So you chose death. Let me send you on your way."

Leo pushed off of his feet and clashed head on with lion head man.

The lion head man sneered. Competing with me with strength? Fool!

The muscles on his arm swelled up as he punched at Leo. Black colour gleaming with a hint of red cladded his arms.

Leo didn't bat an eye. His sword turned blackish red as he slashed his sword.

Slice!

Sword rays flashed. The lion headed man was stunned. He glared at Leo with blood shot eyes.

He wanted to speak but he couldn't as his head slowly slid down his throat.

Her pride didn't allow her to surrender but if she doesn't she will die. Unwilling to surrender she chose to escape.

"Hello, it's a p.l.e.a.s.u.r.e to meet you."

Who!?

When she was rushing away from Leo a sweet voice rang near her ear. The tall woman felt her hairs stand on it's end.

Out of instinct she swung her sword towards the voice. But she hit nothing.

Before she could spot her enemy her body went numb and she fell down powerlessly. The forward momentum made her body roll on the ground a fair distance before she stopped.

Fear filled her eyes. She couldn't move! Her body wasn't listening to her. She even tried to use her devil fruit ability but it failed.

When she was trying to gather her thoughts a beautiful face got close to her and smiled.

"Don't worry. This one won't kill you, since I don't know you if you have some peculiar ability I upped the potency so you might feel a bit of pain later."

Leo flashed beside her and asked, "The islanders?"

Shinobu said, "The crew is on it. They have my drugs so anyone that can be saved will be saved."

Leo heaved a sigh. He turned to the tall woman and snorted before saying to Shinobu.

"Let's split up. These two shouldn't be alone, find the rest of them. If they refuse to surrender, kill!"

After an hour Leo and Shinobu rounded up the rest of the tall woman's and the lion headed man's crew.

They were either killed or arrested. Mace checked their identities and found out they were subordinates of a Yonko.

The lion head man was the subordinate of Hundred Beast Kaido.

The tall woman is one of the four sweet commanders and daughter of Big Mom, Smoothie.

Mace frowned when he got the information. He reported it to Leo who waved his hand.

"It doesn't matter which faction they belong to. Their dispute led to the death of innocent people. Throw them to the brig!"

Mace did as he was told. Smoothie had a wretched expression when she was carried to the brig. Her face was pale and she was sweating a lot.

The crew involuntarily trembled when they saw her. They knew this was the handiwork of their captain's wife. Thinking back to how she experimented new drugs on prisoners sent a chill down their spine.

They were glad she was on their side.

They stayed at the island for a couple of days. Shinobu helped with the wounded while the crew provided help to build temporary relief buildings.

With Shinobu's excellent medical capabilities even life threatening wounds were taken care of. The islanders were full of gratitude towards her.

After making sure the island was on the right track they left for Marineford.

On the ship Leo held a devil fruit. This was the cause of the dispute between two Yonko subordinates.

Paramecia, Devil-Devil Fruit.
