Here's part 5 now. -_-
While Akainu was ranting at his former comrade's 'betrayal' Luffy saw an opportunity. He grabbed the biggest ice block he could get his hands on and threw it at the Admiral.
"OI AKAINU! Didn't you say 'It's not wise to turn your back on the enemy?!" Luffy called out to him.
Akainu turned around to notice the iceberg travelling 60mph at him.
"Hmp! Did you really think that would startle me?" he said half-heartedly "Get serious!" as he turned his arm into magma and vaporised it instantly.
But he failed to notice in time that Luffy launched himself towards him soon after.
"Gomu-Gomu no Stamp!" kicking him right the face drawing a bit of blood.
"Damn you!" he cursed slamming his fist on the ground.
"Kazan Geyser!" as the ground began to shake violently.
"Nani?" said a confused Luffy.
He looked around to see the ice melting around them and evaporating rapidly. Suddenly several geyser of lava erupted from the ground beneath causing Luffy to fall back try and avoid them. However, the last column of magma burst out right next to him.
"AAAHHHHH" the Yonko screamed as he was sent flying back.
Luffy was alive but nearly had a concussion and suffered horrible burns from the blast. He was flat on his face but lifted his head up and could hear clearly what Akainu had to say.
"What's wrong son of Dragon?" Akainu said coldly as he was burning. "Even though you're now that you're one of the 4 strongest pirates you're still a pathetic piece of shit!"
Luffy growled as the pirate tried to gather up enough strength to try to pull his body back up.
"IS THAT ALL, MAGGOT?!" Akainu shouted as he kicked Luffy in the teeth spending him flying backwards. "At least try to die like a man!" he insulted.
"It must be so painful to still be so weak, despite being a 'Threat to Justice" he mocked
Luffy could only stagger to his feet.
"Is this all there is to the 'man who'll turn the world upside-down'? I'm not convinced!" the Admiral continued as Luffy panted heavily.
"Look at you, it appears you're about to die on your feet." He said "Seeing at you in this state almost makes me feel sorry for you" he said with a bored expression "Almost."
"But unfortunately for you I'm just getting warmed up a bit" he boasted as he turned his body into magma.
Luffy tried his best but fell back on his knees.
"Tsk, I guess being pitiful beyond belief must run in the family" Akainu said as he leisurely walked towards Strawhat."
You truly are Fire Fist Ace's little brother" he spat.
That last comment hurt more than his wounds.
"What the HELL DID YOU JUST SAY?!" Luffy screamed with rage burning up in him.
"Oh, I guess you didn't hear me the first time" he said with a smile" Alright I'll repeat myself. I said 'You. Are. As. Pitiful. As. Your. Broth-"
"SECOND GEAR" Luffy roared cutting him off.
"GOMU-GOMU NO… JET AXE!"
His drop kick up turned the ground but he missed his target as Akainu jumped back.
"It appears I touched a nerve, eh?" taunted the Admiral.
"SHUT UP! DON'T EVER SAY ACE'S NAME AGAIN, YOU BASTARD!" Luffy screamed to the top of his voice.
Luffy began charging at him but Akainu just stood still.
"Why's he just standing there?" thought Luffy.
The Fleet Admiral just calmly took off his black gloved and put them in his pockets. This caused Luffy to raise an eyebrow.
"The hell, are you doing?" asked Luffy.
"Son of Dragon…" said Akainu scratching his chin. "After testing your abilities first hand… I have decided… that using my Magu-Magu no Mi powers isn't really necessary to exterminate you."
"What?!" shouted a deeply insulted Luffy.
"Yes. I have come to conclusion that my bare hands alone will suffice" he calmly said.
"Who the hell do you think you are looking down on me?!" roared Luffy as he charged again.
"Sugi!" cried an impressed Brook.
In less than an hour Kuzan had completely decimated most of Big Mom's pirate army with only minimal effort.
"Wow! He made short work of them" commented Sanji.
"Heh, I bet you feel pretty useless compared to him" mocked Zoro.
"You're the one who's useless, marimo!" retorted the cook as they bickered.
"This guy is so strong… yet he still lost to Akainu…" said a concerned Chopper.
"I wonder how strong the Fleet Admiral?" wondered Usopp.
"Oi, the explosions… back where Luffy is… they've stopped…" said a distressed Franky.
"Does that mean the fight is ov-"
"No, I still feel their presence" confirmed Robin.
"Anyway thanks for the help Admiral" thanked Usopp.
"Arara, I told you to stop calling me that Long-nose, I'm not an Admiral anymore" Kuzan said coldly to him.
"…..Thanks for the help ex-Admiral!" said Usopp trying to correct himself to avoid insulting him but failed miserably.
"Do you want to die?" he retorted popping a vein.
1. Play 'Gomu Gomu no Bazooka: Part 2' (The part where Luffy defeats Arlong) until the first xxxx.
2. After that play 'Difficult - Shichibukai".
Kazan Geyser - literally meaning "Volcanic Geyser": Akainu puts his fist on the ground chanlelling magma into it. This is followed by serval geysers of lava to burst out from the ground.
Next Chapter will be up shortly. Don't forget to Gomu-Gomu no Jet Pistol that favourite button or Kuzan will give you frostbite.
