The first time big mom used ikoku she cut King Baum with it. You seriously need to stop coping . Shanks is a swordsman . He’s using adv Coc on his blade and swing it just like zoro . There’s no mystery here
Base TB one shotted fresh G4 Luffy too.
I'm certain even Act1 Luffy with G4 has better endurance, will power, durability than any version of Law ......
It's Oda inconsistent writing.
When the main battle starts you cannot get one shotted again just like that because fighting cannot go back and forth otherwise. That's why Luffy contines to eat several Kaido CoC attack when the plot requires it...
Kaido could do the same with high end attack of TB to current Kidd
It’s absolutely trash. But when oda needs to write trash to keep his sales up, so be it. But then I don’t need to put this much work and free time in a forum and community which only is interested in clowning me for having higher hopes into odas writing abilities.
