Still require strength to match the clash, unless you are saying Luffys adv CoC vastly outstrips Kaido's by a large degree to counteract Kaido's strength + his adv CoC if he was suffering from a raw physical strength disadvantage.
Luffy played around and ran with a giant ball of gold in skypeia, Zoro's lifting feat in the arc immediately prior was to slowly handle a much lighter hollow building.
Luffy split W7 with a show of brute force, while Oda gave Zoro the feat of cutting a chimney, far less impressive strength wise.
4000vs 2200
Luffy is a brawler, the grandson of the best "strongman" feat character Garp, he is stronger than his subordinate in raw strength, do you think Zoro has stronger base punches than Luffy?
Stopped a ranged attack for a split second and had his body destroyed despite being teleported, vs fought on level with Kaido for 30 minuKa,tes, cringe comparison.
