Interesting but how do we turn this into a Katakuri feat?
Katakuri = gear fourth WCI Luffy
Gear fourth WCI luffy can only get knocked out by a full power Thunder Bagua
Full Power Thunder Bagua is superior to full power Thunder Bagua by hybrid Yamato
Unnamed club attack Yamato uses in the current chapter is far weaker due to being in base and not having as much murderous intent and strength
Thus if a full power thunder bagua is what's needed to knock put post WCI Luffy ( who doesn't yet have much amps to his durability ) who is as durable as Katakuri, then Katakuri should be able to tank the attack Yamato used in this chapter since it's far below the needed attack potency to knock him out.
