This hybrid form was supposed to emit CoC from his body which would be something unique
Honestly, Blazing Bagua vs Bajrang Gun should be cut off, instead Kaido should have transformed into his awakening mode after his Death Destroyer Thunder Bagua on G5 and then beat him up with his superior moves. Kidd and Law would join the battle in a 1 chapter fight, injure Awakening Kaido for quite a bit, until Awakening Kaido dishes out Blazing Bagua and G5 Luffy uses Bajrang Gun afterwards.
If Oda wanted to let Luffy solo Kaido, he shouldn't portray him like a jobber afterwards Post Wano lol. He's getting embarrassed by a dying old man.
