Shanks approaches Whitebeard as they are the only remaining group on the island. Beast pirates have already retreated, and Marines just left the island. The island is under the territory of Whitebeard.

"You seem to regain your strength back?? How??" This was the first question that came to Shank's mind. Not just Shanks but everyone who met Whitebeard after his fight against Madara had the same question.

"Why would I tell you brat!" Whitebeard retorted back to Shanks. To Whitebeard, Shanks always made him remember that guy who once gave him that deep scar on his chest at God Valley. It didn't help any bit that Shank's face resembled him a lot with the same shade of red hair, although a completely different hairstyle.

Still, the brat who once was an apprentice on Roger's ship became strong enough to earn the spot of Yonko is still a fact. This increases more signs of some kind of connection between Shanks and that Man.

"Come on. Didn't I help to stop this war" Shanks replied. Whitebeard got annoyed as it can seen on his face.

"I didn't need your help brat!! I could have finished them all off by myself." Shanks also getting annoyed internally. He is Yonko for god's sake but he still is getting called a brat by Whitebeard. He reached the top with his own strength and Haki, just like his Captain. And would probably go even higher, even if losing an arm was a setback he will still go higher.

It was obvious that at this point both were annoyed by each other. 

"Alright alright. But who is that guy with Red eyes that fought you." Suddenly Shanks tone changed to a serious one, and so did his expression. It is not a normal occurrence for a new fighter to pop up with enough strength to contend with Yonko. And even defeat them.

The other reason is Whitebeard's health. After his fight with that mysterious guy, his old wounds were healed and he regained his strength.

Marines and Yonko, even some Shichibukai such as Mihawk, Crocodile, and Doflamingo know that it has to do something with that Red Eye Guy. 

"As if I would tell you. Go knock yourself out at some random island outside my territory." With Whitebeard turned around and walked to his ship. Shanks was still standing there staring at his back. Sensing his strength. After a few moments, Shanks also returned to his ship, leaving the devasted island.

"Boss!! How did it go?" Lucky Roux asked while chewing on meat. 

"I tried but got no information on he got healed or about that red eye guy." Shanks replied after sitting on a chair where Benn Beckman was sitting. 

The first mate poured a shot for Shanks. He had to fight Big Mom while suffering from Hangover. Then he didn't get much rest as he had to rush to this island to de-escalate the situation.

Shanks took the shot and let his body relax. His mind still thinking about Whitebeard and the mysterious Madara. 

"Benn, put our guys to find information about that red-eye guy. The situation of Whitebeard healing must be connected to him somehow." Shanks said contemplating a bit.

Benn took a puff and gave a nod.

"Boss. Did Whitebeard *bite a piece of meat* called you brat again?!" Lucky Roux asked with a mischievous voice.

"Ugh!" Shanks makes an ugly expression and takes another shot.

Everyone correctly guessed he got called brat and laughed at him. They won't miss a chance to make fun of their captain.

Moby Dick,

New World, Grand line

"Marco. How is everyone?" Whitebeard asked with the hope that the death is as least as possible or even not.

"Everybody is alive. Just injured and exhausted." Marco replied while he was examining his brothers.

Hearing this, Whitebeard was delighted that no one died and they did considerable damage to Beast pirates and Marines.

"Gurarara~ bring out new alcohol and set up a feast. We have shown that lizard and those dogs that we are strong as ever." 

Soon the ship descended to a full-blown party with the smell of food and alcohol lingering in the sea. It was like a floating party light under the moonlight. Everyone was happy and celebrating.

Meanwhile, in the Óneiro Kingdom, the analysts were busy compiling report after report.

They observed the fight and are making profiles of every individual that was present on that island. what was their power? The extent of damage of their attacks. Which tactics were employed? The strength of their ship and its capabilities such as range, maneuverability, armaments, and accuracy.

They were especially focused of flying units as the Oneiro Kingdoms want eastablish and maintain air superiority in this world. Kaido, King, Marco, Kizaru. These individuals are studied in depth and soon countermeasures are going to be discussed as well.

"its finally over. What do you guys think?" Dev asked other's thoughts who were present with him.

"The flying units are a problem for us. They can lock down airspace by themselves such as Kaido and Kizaru. We have to come up with measures or with more firepower. For the ship, they can be easily dealt with from a distance and our defense mechanism should be able to defend our ships but I think we should still increase their ammo and reduce reload time." Elly said as she was focused on the biggest threats to their air force. Naval battle is a piece of cake as long as they maintain their distance and a major player isn't present like a yonko or someone long-range attack.

"Kizaru power works on the same principle of light. He can only go straight and cannot change his direction mid-flight. To change direction, he had to materialize again and aim again in a new direction. But I believe he can also use the mirrors as well or any enough reflective surface. Also, he has to charge his attack. fast attacks can be as strong as bullets or slow-charging attacks can powerful as bombardment. His heavy reliance on the Devil fruit is visible as he could have used his haki for various situations but he still went with his Devil fruit. Logia intangibility is another issue that needs to be addressed." Tobirama gave his input as he came up with important points as of now. He needs to study more to find more details.

"Kaido's strong body along with his Devil Fruit and haki makes him dangerous for our force. Our military weapons won't work on him and our ships are in danger near him. We should keep our navy as far away as possible from him. It seems like his only weakness is strong Haki and internal damage of any kind. He is extremely destructive to his surroundings and doesn't care much about his troops except his top cadres. Lunarian King too is an issue but isnt fast enough as Kizaru but is extremely agile in the air. Just need to make sure that weapons hit him. Queen is Mechanical and I believe heavy attacks should work to disturb his inners. Jack is extremely Durable and thick-skinned. we need more penetrating power or something strong enough to cut him." 

"Marco's issue is intangibility in his full transformation but not nimble or fast enough for us to deal with him."

Madara's analysis of Flying units ends on the weakest opposition. 

"other two Yonko? can we deal with them?" Dev asked his friends.

"Shanks attacks are powerful and fast. Since his sword skill is second best in the world, he is not affected by his stump. His crew is good and powerful too with good cooperation. They seem to cover each other weakness as well as power each other up." Madara said after thinking a bit. There is more need for research as the fight ended quite fast and dumbly too.

"Big Mom is just a walking behemoth. She seemed to be extremely easy to agitate and can be easily destructed as we show how a fat guy from Shanks crew threw a big cake for which she let go of her defense to eat it. But she is durable enough to shrug off his crew's attacks except Shanks's attacks. She also seemed to be quite unconcerned for her own children in some way as she didn't care much for her injured children. But nonetheless, she is a monster with somewhat stupid behavior. we need more research on her behavior and psyche." Tobirama gave his input. As a shinobi, actions and decisions on the battlefield can tell a lot about a person therefore easy for tobirams to analyse fighters. But seeing Big Mom's monstrous strength and durability but stupid childish tendencies. he can't help but be perplexed. 

"and the so-called warlords of the sea?" Dev inquired about the next group.

"no cooperation, inside fights, more destructive to allies than to the enemy, no care about friendly fire. These are common points amongst most of them." after watching over the battlefield through satellites, his analytical mind was working all way but he couldn't help but think that their cooperation was like of a new genin fresh out of the academy with the strength of top jonin.

"except Mihawk, maybe Kuma too but everyone else is trash. Bunch of brats" Madara said bluntly as its true. They are powerful forces but highly unstable. They do not mix well.

Dev couldn't help but let out a small laugh.

"Don't think much about them for now. I will send whatever info I have on everybody tomorrow. it's already late so how about we all take our leave?" Shion, Schneizel, and Shion are not present and are already left in the morning. So it was only Dev, Elly, Madara, and Tobirama present.

Everyone agreed and took their leave so they could continue their diplomatic meeting with Ryugu Kingdom tomorrow.
