Kaidou's Defeat exactly mirrors Enel's Defeat
Enel was planning to destroy Skypiea using Maxim & Kaidou was planning to destroy Wano using Onigashima
Enel was so strong & no one in Skypiea could fight him except Luffy, & same thing is happening in Wano with Kaidou
They are like Invincible Villains
Many tried to fight Enel but got destroyed & same thing happened with Kaidou
Actually Supernova standing against him is kinda similar to Last Survivors of Skypiea Survival Game standing against Enel. However the last Fight was between Luffy & Enel/Kaidou with a Female & Talented Kid being the closest observants (Nami/Yamato & Aisa/Momo)
Near the end of the Fight, Skypieans prayed for God to save them & the Scene played as if Luffy was that God saving them
Which is similar to Luffy who actually unlocked his Godly DF Powers & saved Alliance from Kaidou & continued their Fight.
(Next Two Lines contain Spoilers of Chapter 1048, you've been warned)
Enel's Fight ended with Luffy's Gigantic Punch which Enel tried to counter by Transforming into his Strongest Form (Covered in his Element). And Kaidou is doing the same thing & empowered himself with his Flames to showcase his Ultimate Dragon Form
So in my opinion Luffy is gonna knock out Kaidou & defeat him similar to the Fight against Enel,
However Enel wasn't knocked out for long, and he re-awakened very shortly after & his Final Scene was witnessing the Moon which represents his Inner Dream & what completes him (According to his own words)
So Kaidou will re-awaken & he will be faced by the Moon Representative who will give Kaidou what he really wishes for & believes completes him & that's obviously his Death, with The Moon being Zoro. So expect ZKK to happen in the Next Four Chapters.
We've made a Theory before that Chapter 1049 mirrors Chapter 49 which is titled "Storm", so that should be the End of Raid imo.
But if we check Chapters 50, 51 & 52, we find that they were titled respectively: "A Parting of Ways", "Roronoa Zoro Falls" & "The Oath".
Actually Chapter 950 is also titled "Warrior's Dream" & Chapter 951 'Rampage"
I also believe that once Kaidou is knocked out, CP-0 will declare his Defeat at the hands of Luffy & then leave.
So they will think that Kaidou was defeated & killed by Luffy & they won't witness or know about ZKK. Hence why Luffy gonna receive a Huge Bounty while Zoro will only be credited for defeating King & his Bounty will be around 1.6B or little more
