Jon suddenly appear and stop Big Mom's sword attack. He is in his kyuubi chakra mode and he make a hand chakra hand to grab Napoleon. Then Jon make a small chakra hand from his stomach and grab Luffy's head and teleport them away from there.
The Straw Hats are relieved to see Jon came in time to save Luffy. Jon look around and see his side is on the losing end. The fasting really affected their performance in battle.
Jon then make many clones and they all flashed to the Straw Hats & Giants. Then Jon & his clones teleport all of them away to the safety. Big Mom pirates try to stop him, but he's too fast in his movement.
Jon deactivate his Kyuubi chakra mode, and his body is also full of injuries. The Straw Hats are surprised to see Jon have this much injuries. They never see him like this since Whole Cake Island. His opponents are 2 Commander, so he shouldn't get hurt this much.
"I guess empty stomach also affect you, huh?"-Jinbe
"Of course, i'm still a normal human, so i need food."-Jon
"Normal? You?"-Usopp
*BONG*
Jon knock Usopp's head because his word pissed Jon. Jon is a normal human, he just grow very strong, stronger than average humans. He is not a hybrid, mutant or cyborg, so he is definitely a 'normal' human.
"Demon Eyes, where's Katakuri & Smoothie?"-Oven
"Why don't you find it out yourself?"-Jon smirk
"You- Don't tell me-!"-Oven
Jon just grin and didn't tell them anything, like what Oven asked. Jon know they think that Katakuri & Smoothie are dead, but they're not. Those 2 are very resilient and won't die that easily.
Sure he fight them with the intent to kill them, but that's how every battle is. Jon have defeat them, but he doesn't have reason to kill them. But they have severe injuries, so it will be up to them to survive or not.
Katakuri & Smoothie are not innocents and have killed people, but so is Jon. He doesn't have personal hate for them, even when they attack his crew today. This is a normal thing in Pirate World, and if he keep hating people just because they're his enemies, his life will be so sad.
"You defeat them?"-Luffy
"Yeah, it's a tough battle."-Jon
"Tough? For you? Did you really go all out?"-Sanji
"I did."-Jon smile
The others didn't believe him, but they can't prove anything. It is impossible to believe that Jon go all out to fight 2 Commanders, and it took this long. Jon have defeated Kaido, then defeat Ryokugyu & World Government at the same day, so if he go all out, he should have won earlier.
However, they can't prove anything and can only accept it. Jon is also have many injuries, so he appear to really go all out. Even if he doesn't, they don't really care as long as he's fine and everyone survived too. No one on their side have died because of Jon's clones help.
Jon's clones teleport those who are in great danger to safety every time. The Straw Hats & Giants small number is also a luck because Jon's clones can watch every one of them. That's why no one care if Jon go all out or not, it's his battle, and they have theirs.
They just can't guess that Jon use his battle to train. Jon also want his friends to grow through this hard battle. They are really in their limit now with their weakened state, so they will need to surpass their limitation, and grow stronger than before.
"As i thought, you'll really be a nuisance in this plan, Demon Eyes. Well, your whole crew is a nuisance, but you're the biggest nuisance in here."-Big Mom
"Oh, thanks. Usually people will say Luffy is the nuisance, so you say that i'm the biggest nuisance here really make me embarasses."-Jon scratch his head and smile embarassedly
""THAT'S NOT A COMPLIMENT!""-Nami & Usopp
"Well, whatever, you guys have done great. To fight to this extent with your empty stomach must be hard. You must've surpassed your limits a lot today, so let me take care of this!"-Jon activate Kyuubi chakra mode.
"Wait, Jon! Let me fight her, this is my battle, i need to finish it."-Luffy grab Jon's shoulder
Jon look at Luffy, he is in bad shape and can't move that well. However, Luffy still want to finish his battle with Big Mom. Even if Jon is stronger than him now, Luffy is still the Captain. He has his pride to take on the strongest enemy and protect his crew.
Jon see Luffy's eyes that are still full of life and smile. Luffy won't give up easily on his fight, and will finish it. Even if he's beaten black & blue, he will still stand. So if he want to fight now, Jon will help him to have his fight.
"Fine then, just don't die!"-Jon
"I won't."-Luffy
Jon smile and put his hand on Luffy's shoulder. Then suddenly, Luffy's body is covered in red chakra that shaped like Jon's jinchuriki mode, but without tail. Luffy feel his energy restored rapidly and his wounds are slowly closed.
"This is-?"-Luffy is surprised
"I share some of Kurama's chakra to you. You can't utilize the chakra, but it will give you some energy for your battle. The fast is still some hours ahead, so you won't get any energy from food. Just use this energy and fight well!"-Jon
"Alright."-Luffy grin
Jon nod and turn back to the Straw Hats & Giants.
"What about you guys? You still want to fight or not?"-Jon
"Of course."-Zoro grin
"We won't quit after going this far."-Sanji
"We Giants are warriors, we never quit our battle until we finish it."-Hajruddin
""THAT'S RIGHT, WE NEVER QUIT.""-Giants
The Giants start to roar excitedly and get ready to fight again. Jon smile at this, their spirit haven't withered even though they're on the losing end.
"Then, make sure you win this!"-Jon
Jon make 5 clones and run around to give his allies Kurama's chakra. He start with his crewmates, then to the Giants. Their number is small, so Jon can give them more chakra than when Naruto give the shinobi alliance Kurama's chakra.
"Amazing, i never have so much power like this."-Nami
"He share this much power for everyone, just how much is that Nine Tailed fox's full power is?"-Jinbe
"Who knows, Jon never told us anything about it."-Robin
"It doesn't matter, what matter now is that we can finally kick their ass."-Zoro
Jon finish sharing chakra to everyone, and he stay at the rear with Jane. Then Jon clap his hands and gather nature energy. He help Kurama to gather energy faster, so he can keep supplying chakra to everyone.
Everyone feel their energy filled at rapid speed and their wounds also closed. The Big Mom pirates are surprised at this sudden change. They can feel with their observation haki that the Straw Hats & Giants are gaining energy rapidly.
"!? WHAT ARE YOU DOING? DON'T LET THEM RECOVER FULLY, ATTACK!"-Perospero
"SHIT, THAT'S RIGHT, ATTACK NOW!"-Oven
Big Mom pirates start to attack the Straw Hats & Giants. The Straw Hats & Giants also didn't wait and immediately rush to attack their enemies. The second round of the war have started, and this might also become the last round.
~On another coast~
Katakuri & Smoothie are lying on the ground with many injuries. They've been defeated by Jon that didn't use any jutsu or even his special eyes. Now they can't even move a finger because they're exhausted and full of injuries. They have many long battles that lasted for days. But this battle with Jon really tire them out.
"That guy is a monster. He grow so rapidly just in 9 hours."-Smoothie is in disbelief
"We can't expect less from a guy who defeat Kaido alone."-Katakuri smirk
Previously in their battle, they saw Jon's growth with their own eyes. Jon didn't use any of his jutsu and just utilize his haki & fighting skills. However, Katakuri & Smoothie didn't take him lightly and fight seriously.
~Flashback~
At the beginning of their battle, Jon still get hit many times even with his future sight. It's hard to fight without chakra at all, because Jon always used it. He always use chakra in high level battle even if it's just for enhancing or flow it on his swords. But now, he didn't use it at all even a little.
Instead of chakra, Jon maximize his haki on this battle. He used all 3 types of haki to the max and used them as efficient as he could. He doesn't use them excessively, because using too much haki will tire him out faster and it's dangerous.
Still, he keep his observation haki active all the time, because if he missone moment, he can die. So what he minimize is the usage are armament & conqueror. He also just use haki projection when Katakuri use it to attack him.
Jon was in the bad situation at the beginning. Fighting 2 Commanders just with his body & haki is really hard. He realized that he is too reliant on his chakra & jutsu to fight. He is a shinobi, so it's normal, but he want to be able to fight well without any chakra too. He don't want to be helpless without chakra.
Jon keep fighting with Katakuri & Smoothie for hours. He was in big disadvantage in the beginning and can't land any hit. But he start to adapt and the hit that he took lessened. After some hours, Jon finally get even with them and start to hit them.
Katakuri & Smoothie know the situation have changed, so they raise their game. They started to go all out and use all their power even if it will tire them fast. Jon start to get in disadvantage again with his enemies going all out like their life is in danger.
'They raise their attack power? It will tire them out faster, but i think they can only do this and take me out faster. Too bad i won't let that happen.'-Jon grin
Katakuri and Smoothie use all their strength and raise their attack power. Their hit become stronger & heavier, and their speed raise a lot. This start to put Jon on disadvantage again just after he can get even with them.
However, Jon still use the same tactic and power like before. He didn't see any benefit in using more power like them. His fighting style is designed to minimize his energy usage so he won't get tired fast.
Jon dodge as close as he can, and redirect the attacks. Jon didn't block any attack, because Katakuri & Smoothie use big power on their attacks. He will need to use big power too to block those attacks, and he doesn't want to waste energy.
After some hours, Jon's move become swifter and he start to get even with the enemies. Then he start to get better & better, and gain advantage slowly. Katakuri & Smoothie can't use more power, they've used all they have and Jon still keep up with them.
9 hours after they start their battle, Katakuri & Smoothie get defeated. They've run out of energy after using all of their power for hours, and their injuries are stacking. They're not Jon who get his wounds get healed automatically because of his gene, albeit slowly because he suppress his chakra.
Jon defeated Katakuri with a diagonal sword slash, and Smoothie with a kick on the head, both with haki projection. Smoothie passed out immediately, but Katakuri is still conscious.
"*pant pant* It's a tough battle, you two are very strong."-Jon
"*pant* Stop... lying! If you go... all out... it won't be tough... at all."-Katakuri
"Well, that's up to you wether you believe it or not."-Jon
Jon go to the side, but suddenly he get an information. This is when Jon know that Luffy is in danger, so he immediately activate Kyuubi chakra mode and teleport to Luffy.
~End of Flashback~
"Why did he suddenly leave?"-Smoothie
"I don't know, but he seem to rush, so something important must've happened."-Katakuri
"What should we do now?"-Smoothie
"Rest for now, we'll return after recovering some stamina. Demon Eyes have returned there, so the situation will change. I hope our siblings are fine."-Katakuri
