What fight?
We only know he landed one hit on BB and that too in mid air.
After that, he was lying on ground unable to move while Teach was exactly how he was after taking the first attack.
You can resort to panting or bruise scaling but one hit on someone who was on mid air and had no proper footing doesn't make it high diff fight.
That sneak attack by Bepo means nothing if BB is fine.
Anyway, on another topic...
BB was cool AF. What you simpleton with powerscaling minds overlook is Bb portrayal is exactly like luffy....
Causally asking kuzan to join them
Casual in fighting
But ideally different. Luffy views nakamas as friends and BB view them as a group with mutual interest.
