I got Blackbeard & shiryu Extreme Diff. BB would beat big mom from negating her devil fruit and most likely negate her homies and max her out the quake fruit with big mom putting up a good fight. While kat would beat shiryu from possible awakening cover large areas even if he invisible if future sight can’t see the invisible fruit and then bb beats kat in every way beat observation haki while negating his devil fruit.

BB & Shiryu, high - extreme diff.

Bb just stuns katana and big mom will be too busy with invis dude

Bigmoms fatass prob couldn't see him ngl evean if he wasn't invisable

Big Mom and Katakuri. Blackbeard is NOT beating Big Mom even with his fruits. Both BM and BB are arrogant and overconfident, but I say BB is slightly more overconfident in his abilities while Big Mom herself is a freaking tank that can take a beating. BB can as well, but Big Mom has shown better endurance, much better durability and AP, and overall better stamina.

As for Katakuri and Shiryu, Katakuri has this. But Shiryu can likely take a beating ngl. Plus, Katakuri can see the future and evade possible outcomes that would help them greatly. I have BM and Kata winning extreme diff. On top of this, BM doesn't even need her fruit. Yeah it'd make a difference, but she really doesn't need it considering she has both advanced armament and advanced conquerors while neither BB or Shiryu as of right now doesn't have any form of advanced haki, let alone conquerors coating.

The Haki argument isn't great. By that logic, Luffy > Mihawk because Luffy has ACoC, ACoA & ACoO while Mihawk only has CoA & CoO.

Luffy also has BDFI CIA FBI IRS BDFI DDLC OH SGMA RZ and don't forget JB MDL and MDG

Big mom has shown to have better haki and durability feats but against stronger opponents who shattered her arm she never used it against them. In character she leans towards devil fruits and has shown complete incompetence with them or her kids. And BB most likely could cancel out her homies while Bigmom has shown once she uses Acoc her durability downs as shown when Capone bege she on the time he saw her bleed ever. While BB was shown taking shock willie from law (but big mom did take stronger version) and shown never sleeping once for 4 days while fighting roger pirates

@IKTime I never said BM instantly wins bc she has advanced haki, it just makes a big difference, especially considering Big Mom can take a heavy beating. The Gura Gura wouldn't do much against her considering BB and Akainu took it quite well from an angry Whitebeard. And she has the stamina to battle for a whole day against another emperor, possibly even three which Blackbeard hasn't shown yet. I'm putting BM over BB solely bc Big Mom would just last longer overall.
