Many of Luffy's attacks, including the base punches that were more effective than Asura in 1010 were unnamed. What is your point.
Creating a THIN cut across Kaido's chest that is now nearly invisible is impressive, but don't blow smoke at it, Luffy's blows are doing far more internal damage.
What the fuck do you mean by lethal, it didn't even knock Kaido down. Zoro has killed ZERO people in the raid, just like Kaido and everyone else. Getting your head smashed by a club IS LETHAL irl.
Ko'd base pre adv CoC Luffy who had limited defense against adv CoC.
