1. And? Even by your standards that is no reason to say she is weaker than Old WB you call half-dead. All Yonkou are on par with each other. Even if one is barely stronger than the other, there is no guarantee that the results would be the same every time.
First of all i was never talking about old WB i was talking about the current Yonko but yes she's weaker than old WB as well she is the weakest emperor and it's painfully obvious.
2. Kuzan was unharmed by the gura shockwave and froze the ocean. The first clash was a stalemate.
Kuzan slipped through WB bisento, trapped him and was going to stab him with ice partizans at point blank range. WB had to be saved by Jozu.
WB only got the better of WB because of a distraction and sneak attack but still lost half his face. Even after the 2 point blank gura punches, even Marco with the WB crew wouldn't harm Akainu.
He was only unharmed cause WB could careless about killing him. If he'd have added Haki to his quake Kuzan would have been ruined. WB was not trapped at all he could have easily tossed away him Bisento with Kuzan on it thus getting him out of harms way Jozu was needed tbh.
Wasn't a sneak attack since Akainu clearly recognized his presence before he was hit. Doesn't matter if he lost half his face or not WB had already been getting stabbed and shot up prior to engaging Akainu in the first place. Whitebeard still won their fight and could have killed Akainu if he decided to keep going after him after that last hit.
3. WB never said he was no longer the stronger. He said he couldn't be the strongest forever as he is just one man with one heart. Old WB called again & again the strongest alive even in his introduction box and in the narration about his death. Old WB was still the strongest in the world but he wasn't beating any top tier because of his heart condition.
Marineford Whitebeard isn't beating any male Yonko. You do realize those boxes are nothing but hype right? It is said that Kaido will always win a 1 on 1. So what should we take into consideration more huh? Whitebeard title was held as the strongest man in the world because of his prime. Not his current feats at Marineford and it's obvious.
Roger was known as the strongest Pirate in the world. If Roger would have lived to 90 he'd still have the title of the strongest pirate in the world even though it's clear that he's not the strongest anymore. Same applies to Whitebeard.
Are we even reading the same manga? Luffy lost countless times.
Twice against Croco. To BM´s revenge army. Frozen and at mercy by Aokiji. On Sabaody Archipelago couldn´t save his crew. Got his ass handed to him at Marineford.
So no, I don´t think Luffy will beat anyone.
Doesn't matter in the end Luffy came back and won. He's the main char thus he can beat any char in the series why? Because plot demands it don't argue with this.
