The exact same thing happened with Luffy's Bajrang Gun. But Kaido's wasn't a bluff unlike Linlin's.
Punk Crash caused her immense pain not felt in decades but you think Damned Punk wasn't anything better? Oda literally wrote you on panel that she was bluffing, what else do you need?
Kaidou met Luffy's Attack with an Attack of his own, that's why he was talking like that
Same thing happened in Doffy's Fight
But Big Mom ate Kid's Attack directly, she didn't counter it with anything
Stop exaggerating please
They defeated Big Mom the same way Supernova Four were gonna defeat her on the Roof, if not for Kaidou's Help
The only difference is that Law & Kid managed to make her more Serious & reveal more of her Techniques
Oda literally prepared you for her defeat with that Roof Fall, showing that Big Mom can be defeated with a perfectly coordinated team-play
But it was never ever implied that Kid & Law are close to her Level
You think Big Mom can overpower Two Top Tiers in a Direct Confrontation while their Subordinates beg her to stop & then she gives them her back & leaves out of mercy
Be realistic please
Even during Dressrosa Arc, i've hyped Law as someone stronger than many Commanders & far far away from Veterans
So i know his worth & same for Kid, but i'm not gonna exaggerate & claim they are no different than other Top Tiers just because they managed to pull a perfect Team-Play
You're making yourself look no different than those who hyped King as Top Tier
Saying he defeated Big Mom & her entire Crew lol
