That's also a scam btw, Kaido didn't have Awakening, Goofy beat Kaido thanks to his DF's awakening and ACoA emission, not ACoC.
Shanks who is pure Haki user is afraid of BB who is the biggest DF merchant ever.
Law's DF beat out Vergo's Haki despite Law's Haki being weaker than Vergo.
Joyboy was a mythical DF user, Gorosei main strengths lie in their DFs, etc.
BB himself says that DFs are worth the price you pay for being weak to the sea. There's certainly a narrative that suggests DFs can and do surpass Haki in general.
- I don't think only ACoA and Awakening would have pulled the job. ACoC was an important factor considering the AP required tackle Blazing Bagua.
- Shanks been beware of BB even before He got the devil fruits though.
- We have many instances of that tbh , The logic of Strong Haki cut weaker haki it certainly true but we Scenes where arnament is broken by simple Pierce or Cut attack. Major example being Hordy Bitting Luffy arnament Arm , no Way hordy had better CoA than luffy. Pierce / Cut attack have tend to show results even among strong haki cases. Also Law cutting Vergo does not mean he has stronger Haki than vergo , it was mixture of Both sword and DF which resulted in that AP which surpassed Vergo CoA level.
- Joyboy is weird Example taken but we also have Pure Haki Guys like Ryuma , Roger , Mihawk , Shanks who are also strong enough to go on par with them. (Now I don't know how massive the Gap is between them , Nika seems to be broken and we all know about MC power creeping)
- BB statement do hold some meaning to it , His Devil fruit is literally alternative to Haki , Gura works as Alternative to ACoA/ACoC and Yami works as General Haki property of DF negation.
I agree to the statement of DF surpassing haki in some cases. But most of the timr haki will prevail.
G5 is ass without Haki , Even Lucci got up in 30 sec.
Though Kaidou is hypocrite himself with using DF in the end instead of Haki focussed attack. But I understand he might not have anything on that scale with Haki so he had to rely on DF.
