The strongest haki users of their respective generation
We know from law, Linlin, and kaido that you can break through devil fruit hax if their haki is strong or intense enough to counter it
Shanks and now joyboy have shown a whole new level of that. The ability to straight up revert someone out of their devil fruit state. Preventing them from using their devil fruit abilities to their full power
Roger having the same ability to use his haki to cancel out devil fruit abilities could how he and whitebeard were equals back in the day
It could also explain shanks and Blackbeard's paths to grow stronger and them potentially paralleling each other
Shanks growing in strength through actually training his haki to the best of his ability. Blackbeard deciding to bet on fate giving him the opportunity to steal devil fruits
- Shanks strengthening his conquerors haki to the point he can negate devil fruit users from using their powers
- Blackbeard waiting for the darkness fruit to come his way so he can do the same but more
- Shanks strengthening his armament to the point he can bypass one’s durability and destroy things from within
- Blackbeard stealing the quake fruit so he can do the same to a greater extent
- Shanks strengthening his observation haki to the point he can view into the future
- Blackbeard probably won’t get a fruit that allows him to view into the future but the love fruit potentially would be the perfect counter to it
- Observation haki is all about sensing another’s will and emotions. The love fruit can fuck with one’s emotions
- Blackbeard probably won’t get a fruit that allows him to view into the future but the love fruit potentially would be the perfect counter to it
