Luffy unlocking Gear 5 and use King Crimson to burn Kaido's butt would be cool.
		
		
	
			Red Crimson.
 
		
		
	
 
		
			G4 verison of his flame-attack? How this will be called?
Red hawk -> Red roc -> Red ???
		
	Red hawk -> Red roc -> Red ???
"Hawk" and "Roc" are both types of birds. A "Roc" is mythical, so the next level should be an even more legendary bird. I can't really think of any bird more legendary than the Phoenix.
I'd guess it would be "Red Phoenix". Personally, I would prefer some other hue of red be used for aesthetic purposes (so maybe "Crimson/Scarlet/Vermillion Phoenix").
			He will show G4+barrier armament first, since all Kong moves he showed vs Kaidou, didn't even use that.
		
		
	
			Or else, the impact and damage he showed should far surpass his Red Roc (G3+barrier).
		
		
	- Red Roc used Internal destruction COA.
- Kaido has been on guard after Red Roc so would likely take less damage.
