Battle Of Wano - The Deciding Factor

This theory is sort of an addition to this previous one I posted here:
Kaido's 3 Disasters - Drought, Winter & Rain

So to fully grasp the following context I'm going to talk about, I would strongly advise you to read my previous theory or read the following spoiler as a short summary containing the most valueable information of the theory:

Spoiler: Summary of my previous theory

The Beast Pirates are based on the Mongol empire.
Mongolia is located between Russia and China and is known for their conquest of China and continuous invasions of countries all over Asia and later on even Europe.
This theory is solely based upon Mongolias failure of the conquest of Japan.
So, merging history with One Piece - Japan represents Wano.
Why? Although Wano might already be Kaidos territory, him looking for Momonosuke might hint at the fact that the conquest of Wano is not fully over yet. And with Luffy showing up in Wano next and most likely defeating Kaido sooner or later, Kaidos conquest of Wano will also end in failure. In addition to that, the majority of japanese fighters were samurai.

As the Mongols were laying siege on Japan it became clear that the Mongols were far superiour to Japan regarding military might. Their weapons and armor were far more advanced and Japan couldn't deal with the Mongols long range attacks as they were mostly samurais and experienced sword fighters. It also has been quite a time of Japans last combat, leaving nearly no commanders with any actual combat experience.
So why did the Mongols fail to conquer Japan in the end?
Simply put, wind. During a big siege in the night, a typhoon caused Mongol ship captains to reembark in order to avoid the risk of being caught off guard by a japanese surprise attack. This proved to be fatal, as only a few ships had not set out at sea and those who did... were all destroyed.
This was a big turning point and more and more battles turned in the favor of Japan. Upon loss of yet another big battle, the Mongols were forced to withdraw back to their ships when yet another typhoon hit them and destroyed most of their ships, ultimately leading to Japans victory.
Years later, there was a second attempt to conquer Japan. However, Japan was better prepared this time. They fortified the coasts and organized their samurai in said regions better. This drove the Mongols yet again back to their ships. And guess what, a massive typhoon rampaged there for 2 days straight, annihilating the majority of the Mongol fleet. After these events, the Mongols never laid siege on Japan again.

According to those scenarios, a person with a power over wind/weather/storm will be crucial for the defeat of Kaido and the Beasts Pirates.
Does anyone come to mind?

Monkey D. Dragon

The obvious first choice would be Monkey D. Dragon. I'm not going to talk about Dragon having wind powers here, there's already several other threads about that: Dragon's Devil Fruit: Storm, Wind, Weather Dragon's Haki - Influencing The Weather Dragon was already investigating in the direction of Doflamingo, having sent Sabo to stop the weapon trading in Dressrosa. He then talked to Koala, who informs him about the weapons containing a substance called Liquor Iron Ore, which can only be found in very specific countries: Right after that, Dragon tells Koala to assemble the commanders of the Revolutionary Army from all over the world, possibly indicating that Dragon knows, where those weapons are produced or at least supplied from. Secretly boarding one of the Revolutionary ships on Dressrosa, Burgess was able to direct the Blackbeard Pirates to Baltigo, the Revolutionary Armys HQ. Upon seeing, how Baltigo got destroyed, I don't think there was a fight, indicating that the Revolutionary Army already gathered the commanders and left for some other location before Baltigos destruction. Adding up that wind is the crucial factor in Kaidos defeat on Wano and the Revolutionary Army leaving their HQ with all its commanders, this might be a hint that those weapons really were supplied from Wano and Dragon wants to put an end to that whole affair. As a sidenote on the thought of Blackbeard: Might Teach possibly pursue the Revolutionaries towards Wano, later aquiring Kaidos DF (strongest Logia, strongest Paramecia, strongest Zoan)?

Taking this one step further...
In popular japanese myths, the god Raijin was the god who turned the storms against the Mongols. For those who don't know, Raijin is the japanese god of lightning. His appearance is that of a tall monk.

Enel

Tall monk? Lightning? There is no doubt that it is Enel, who was based on the god Raijin. But what I'm still struggling with is finding a connection as to why Enel would have a reason to come to Wano and fight Kaido.

Urouge

So I gave this a second thought and came across Raijin Island. It is an island at the beginning of the New World and Urouge was shown sailing towards said island. We don't know what happened there, but I'm sure Oda didn't show Urouge approaching Raijin Island without any purpose whatsoever. So here we go again... tall monk? Lightning? Urouge on Raijin Island! On Urouge we actually have already some facts at hand: Urouge was seen to have Skypian-like wings during his childhood, which now changed to look like wings the people from Birka have: Somewhen during the timeskip he defeated one of Big Moms 4 Sweet Commanders only to be later forced to flee by Cracker: Later on, he was shown to be resting on a sky island. There he met Kaido, who was just about to commit suicide: With those facts I came up with 2 possible reasons for Urouge to go to Wano and after Kaido: Spoiler: Reason 1 Having witnessed the strength of Big Moms crew, he might have decided to pursue Kaido from now on after seeing him in such a (mentally?) weak state. He probably even thinks Kaido is dead? That said, Urouge now sees a chance to go after Kaidos territory in Wano rather than fighting Big Mom. Spoiler: Reason 2 Assuming that Urouge has both Birkan and Skypian roots, he might have heard about Luffy saving Skypiea from its destruction by Enel. Upon looking at Raijin Island and knowing that it was Enel who destroyed Urouges homeland Birka before he became the god of Skypiea, I think it is possible that Raijin Island was once a part of Birka and came down from the sky. The climate change there is very similar to Punk Hazard, only that it was Enel who caused it there - hence the lightning. So Urouge goes to Raijin Island, sees all the suffering the people there have to go through and now is very grateful for Luffy saving the people of Skypiea from suffering the same fate. Urouge finds out about Luffy fighting Kaido on Wano and comes to aid him, finally turning the tides there in the straw hats favor.
