I said Aokiji used his DF to freeze (abnormal status) his opponents. Just like how he did to Luffy, Robin, Whitebeard, Cracker etc.
Moves like that, when gets resisted by haki, doesn't cause any physical injury, it only eats stamina. Just like dr. Q's moves.
Meanwhile you tank Blackbeard's Gura Punch with haki and you still get damaged more than resisting Aokiji / dr. Q's power.
