Even Mr. 3 said if he fought them the 3 BW agents on the island would get destroyed. That’s why he had them take themselves out.
No one's seriously saying that Mr.3 defeated them in direct combat or could take them in a straight fight
But factually they were embarrassed and would've been killed by Mr.3 of all characters
So it's hard for people to suspend their disbelief when D/B come back and are supposed to be these legendary fighters. People constantly bring up Shanks losing his arm to a Sea King and are only now
maybe letting it go due to the Holy Knight seal explanation
