luffy's gears are based on his devil fruit
haki just amplifies those gears
unlocking new haki doesnt mean luffy developed a new fighting style and thus he will make a new gear ffs
mastering acoc gave luffy the portrayal of entering the yonko realm and going toe to toe with kaido...
seeing them wont change anything , those individuals are also bound to have acoc which will just promote kaido's words further
haki surpassing all is just a simple fact , it shouldnt even be a debate
haki specially counters devil fruit abilities too which in itself is the greatest ability...
i think u are also forgetting the example that guy used in order to prove it
the example was gold d roger , the pirate king who reached the top solely with the help of haki
and the ' awakening ' state used against kaido was also coated with coc
with the opponent himself announcing why he will...
