Then again if any Yonko should be lacking in haki all round, Blackbeard is the perfect one.
I always expected he will be the ultimate cliche of relying too much on your DFs and thus getting bested by someone who masters haki well like Luffy now especially as expected.
He could nullify Luffys DF and Luffy would be forced to use haki vs him. Since Blackbeard is the only multiple DF user we know and actively hunts them with his crew, it makes sense for him to wank them the most ofc.
That line from Kaido about Roger actually conquering the seas and haki being supreme feels like something that should have come up vs Shanks or Blackbeard somehow?
I just really hope Oda doesn't fuck up Blackbeards writing especially now though.
