I’ve made a bunch of post in the past on how I believe the fruits Blackbeard has mirror haki and this is another one

- The yami/darkness fruit having the ability to completely negate someone’s devil fruit abilities. Like we’ve seen from Shanks against Aramaki and joyboy’s haki against the gorosei
- The gura/quake fruit being able to generate internal damage and that’s putting it lightly. Just like armament at its most advanced levels
So far future sight is the most advanced form of observation haki but while idk how canon it’ll end up being tbh we also heard that shanks has the ability to basically negate others from using observation haki. Doing so combining his conquerors and observation haki
An ability we could potentially learn more about from Gaban himself the observation haki specialist of the Roger Pirates. So what if his third fruit isn’t seeing into the future but negating it completely like Shanks might be capable of doing. If you think about it the gura/quake fruit doesn’t just mirror advanced armament but advanced armaments infused with conquerors so it would make the sense if it was the same with observation haki
When Luffy used internal armament before he learned conquerors infusion he was still physically touching Kaido
Using the same technique but infused with conquerors he wasn’t even touching him
Blackbeard doing the same with the quake fruit but on steroids
So it makes complete sense why he’d want Hancock’s love/mero fruit seeing as it can mess with someone’s emotions. Emotional control being very important for when it comes to using observation haki
Shakky being able to basically beat the Roger Pirates on her own due to them not being able to control their emotions. Tho idk how Blackbeard getting the fruit would work tbh cause idk I don’t see people falling in love with him but hey I guess anything is possible…
