bigmom, kaido, shanks, mihawk, sakazuki, rayliegh, garp, kizaru, fuji, aokiji, luffy, has greater AP than zoro's ashura, luffy in his base form with unnamed attack is knocking kaido using adv coc whose AP seems to be on the same level as ashura. so base luffy's unnamed attacks has same AP as Zoro's strongest attack. so he aint even in top 10
