I disagree.The Katakuri fight also seemed beyond impossible and Luffy pulled through.He was getting no-low diffed and managed to close the gap mid fight.
The thing was, Luffy could defeat Katakuri with G4, we literally see G4 could damage Katakuri hard, the problem was overall FS with Luffy overcome. And we know if Luffy can find a way to pass FS, he could damage and defeat Katakuri.
But Kaido encounter is total a different case, Oda make it clear in chapter 923 Kaido was a different lvl.
When Luffy use Snakeman and FS, we see a equal match.
Luffy learn Adv CoA to overcome Kaido durability/Skin who is like the FS of Katakuri.
But the different already start that Kaido is more then just his hard skin, Luffy could damage him finally and what? It is like Kaido is top fit while Luffy and co already are exhausted, Kaido was playing with them, not serious(unlike Kata who take Luffy serious and fight with 100%). Kaido is different, he is like Freeza, you though you can finally match him via a powerup and he reveal everytime a new form....
Let assume he also has really a third form ala awakening and let assume Kaido in hybrid already finish the SN, what would this overall mean? That is almost impossible for Luffy to win against Kaido while he using his awakening form, at least without help. They can be happy that Big mom is just joking around too. Do we really think how this could end if Kaido fight seriously with named attacks? FS Luffy barely dodge Base Kaido, thunder Bague can one shot them... He beat of the Scabbards with just swing his club right and left without using any technique...
It is really hard to believe that Luffy can win here without help. Against Katakuri we see that Luffy can hurt him and beat him. However Kaido is like in ever stage league above Luffy. That is not funny anymore, to beat Kaido Luffy would need soo so so many powerups...
And that is the problem, probably Hybrid Kaido already beat them down, now imagine awakening Kaido...
Kaido tank attacks right and left since the raid begin and the dude looks totally clean, as if he never take any attack.
Katakuri FS was op, but we know if Luffy could overcome FS he could fight him back. However how is he now fight back when his hard training with Adv CoA can´t hurt Kaido much as we though at the begin. This men laugh off after taking Gk, he take so many attacks and still stand like it nothing happen to him. With Kaido, oda make it clear that he not use the usually "Luffy attacking with a strong punch to win" methode, this time however it will be probably the hardest match ever. And i doubt 5Sn are enough to beat Kaido...
