Loki killing Harald has no asterisk because before it did happen it was stated only Loki with DF can actually kill him. Harald letting himself be hit has no relevance to Loki attack overcoming regeneration which is passive ability .
Yes you yourself confirmed titles are because of their devil fruits and not because they defeated everyone noteworthy in the world. Seeing how Kaido can turn into a dragon and is Oni no wonder he was given strongest creature , and seeing how WB can literally destroy island no wonder he got WSM title. They were given titles because people considered them strongest .
It doesnt matter MIhawk is from different era , he never did anything noteworthy that would cause people to consider him WSM / WSC instead of those 2.
Mihawk title may be the most legit one because he did actually want to become WSS and was defeating his opponents for that. Yet we also know he did not fight every swordsman outthere . We know he never fought Vista , most likely Fujitora too and for certain he was not facing Shamrock in his quest for becoming WSS.
Unless Oda makes him regeneration merchant like rest of HK and Gorosei for me Shamrock is Shanks with both hands ( manga literally stated their talent / potential is equal ) plus Imu buffs with Cerberus sword .
It will always have an asterisk because Harald was not fighting back, even in his fight with Shanks and Gaban he had already returned the legendary sword. Was Lokis AP higher than Gaban/Shanks? Most likely and which resulted in Harald taking quite a bit of damage. Do you think Harald was using CoC barrier when he told Loki to kill him?
Yes, idk why you are repeating stuff. The point is that their strength, power and feats were what got them the title instead of them going around and fighting everyone to prove they are the strongest.
Bro, you are mixing things up and this is probably due to anti Mihawk propaganda messing things up. Mihawks title is absolute compared to the other two. He made a name for himself before the Great Pirate era, he fought until no worthy opponents were left, he is WSS in name and reality, he is waiting for someone to surpass his rival Shanks and challenge him.
That is such a stupid argument, you haven't fought every swordsman and beaten them hence you cant be called WSS. Wtf is that logic.
And with all that unless Shamrock has haki greater than Venusjuro he will still be weaker than Venusjuro.
