"Iron Fist!"

Accompanied by a thunderous voice a fist clad in busoshoku haki punched out towards Big Mom's attack.

Boom!

The fist and the powerful blast of air clashed against each other. Both the attacks were equal and contented to triumph over the other. The sea beneath them rolled over from the aftershock.

Finally the fist clad in haki pierced through. It dispersed the powerful blast of air.

Leo still had a bit of consciousness and he saw who saved them.

It was an old man with white hair and white beard. He had broad shoulders and wore a white suit. The cloak of a Vice Admiral hung on his shoulder.

Aokiji flashed beside the old man, "Arara, Garp-san, you are late."

The old man named Garp laughed, "Buhaha, dozed off for a bit."

Aokiji wasn't surprised to hear him and turned his focus on Big Mom.

Garp yelled at her, "You old hag, where do you think your are!? This isn't Totto land, get the f.u.c.k out or be prepared to be thrown into Impel Down!"

The marines below were stunned. Vice admiral Garp dared to call a Yonko a hag, they were sweating bullets.

Big Mom growled, "Garp! That kid must die!"

Her eyes were filled with madness and hate.

Garp was finally angry, "Damned woman, you want to kill a marine right before me!? Get the hell out or we are gonna have a brawl right here!"

"Ikaku Sovereignty!"

Garp clenched his fist, busoshoku haki climbed onto it.

"Bwahaha, it's been a while since this old body of mine got some exercise. Let's have a good fight!"

He shot forward like an artillery. Sonic booms echoed as he kicked through the air.

"Iron Fist!"

His fist clad in busoshoku haki struck forward.

He didn't use any sophisticated or complex techniques. He simply used a fist.

This simple fist pierced through Big Mom's attack like it was paper.

"Old hag, with that kind of injury you still have the guts to act so overbearing?"

"Iron Fist!"

It was a simple fist again. However a grave expression took over Big Mom's face.

Garp became famous before the Great age of pirates. Him along with Roger fought against the strongest pirate crew at that time and defeated them.

Among that pirate crew were Whitebeard, Kaido and Her.

He fought against all of them at that time and defeated them with the help of Roger.

He is a marine hero.

He is Garp, The Fist!

Big Mom used busoshoku haki and met Garp's fist.

Crack!

Garp took a step back but Big Mom took three.

"Do you really want to continue, you old hag. That brat's sword energy must be wrecking havoc inside you. Are you sure you can take me and that rookie Kuzan at the same time?"

Hearing him the madness in Big Mom's eyes toned down. She glared at Garp for a second and flew back to her ship.

"Retreat!"

Her voice echoed through the area and all Big Mom pirates immediately retreated.

Before leaving Big Mom shot a glare at Leo and said, "You won't be so lucky next time."

Leo scoffed.

Soon Big Mom pirates retreated and Garp let out a sight of relief.

"Your bluffing is getting better, Garp-san."

Garp glared at him, "Shut it, rookie. No matter what, she is a Yonko. If she is determined to continue the kind of destruction she can create is unimaginable."

Aokiji didn't respond and looked over at Leo. Garp also turned his head.

"This brat is good. He actually managed to injure that monster."

Aokiji nodded, "Though he lost his battle capacity after that, it's still shocking."

Garp agreed. To injure Big Mom is a tall order and this kid had done it.

"Looks like Sengoku lucked out."

He mumbled to himself. Aokiji pretended like he didn't hear anything and ordered the marine to take care of the injured and check the casualties.

And like that the battle came to an end.

Leo was seriously injured and had used up every last drop of his strength, he lost consciousness the moment he saw Big Mom retreat.

Marineford.

A battle report was placed before Sengoku. He was serious as he looked over the numbers.

"Luckily we didn't lose any of the vice admirals. And that kid actually managed to injure Big Mom!"

Right at this moment Garp walked in like it was his backyard. He pulled a chair and sat down before taking out a pack of rice crackers and chomping on it.

Sengoku asked, "How was the new kid?"

Garp had his mouth filled with crackers as he said, "He is quite terrifying. His sword realm has obviously reached it's pinnacle and he has basic haki mastery but his techniques are subpar."

Sengoku nodded, "So you think the same way."

Garp suddenly said, "Sengoku, let me give you a warning. Make sure that kid doesn't meet any world nobles."

Hm?

"Why?"

Sengoku asked puzzled.

Garp got serious, "He is quite easy going and loves to travel but his sense of justice is very strong and pure. If he sees the how world nobles treat others, he might kill them."

Sengoku waved his hand, "Don't worry. He is clever, he wouldn't do something so reckless."

Garp shook his head, "That was true before but not now."

Sengoku waited for him to continue.

"Big Mom killed an entire town because he arrested her daughter there. She wanted him to know the consequences of his actions.This had tremendous effect on that kid, and it changed him."

"I read his record, of all the pirates he arrested he only killed a very few. It can be seen that he will only kill when there is absolutely no other option. He is a sane and thoughtful person."

"And Big Mom put a big dent on that character of his. You did read the report right? When he saw those decapitated heads he didn't go crazy, rather he became calm and ordered the men to bring up Big Mom's children. He then swiped their heads off right infront of Big Mom."

"His purpose for that was simple. He wanted her know the consequences of her actions. His eyes contained ruthlessness, madness and murderous intent. However he didn't lose his sanity, he controlled all that emotions and battled like it was normal."

"He is someone who follows the rules, and he will enforce those rules. He know that certain things can't be helped, and that there is a dark side to this world."

"Now it's different. He might still follow the rules, but he won't look the other way anymore."

"A certain ruthlessness and lawlessness grew inside him in this battle. He will enforce justice, be it a pirate, a civilian, a marine, or... even a celestial dragon. He won't hesitate anymore, he will kill anyone who cross his bottom line, irrelevant of their status."

"You should understood how dangerous such a person is."
