Vergo was using his astounding Armament Haki to singlehandedly run through 3 different people, dominating them and making them look like a fool before his might
Even Sanji’s monsterous Black-Leg style folded when pitted against Mr.Vergo for too long which solidified the fact that he is M3 level threat and soundly above Luffy’s wings, he’s already portrayed as being Luffy level opponent but Luffy was dealing with Caesar.
Law who is comparable to Luffy is forced to bare the task and is getting bullied which narratively demonstrates that Vergo is too much for them to handle, not to mention Mingo. Vergo then goes on to expend more of his haki embarrassing Smoker, his infamous Demon Bamboo breaking the mad dog’s signature weapon, this feat taking a large amount of haki.
Vergo like Kaido was running the gauntlet and his stamina was so great it didn’t even seem to hinder him but that’s just on the surface, his haki was getting weaker gradually as I already proved with the scan and by using Kaido as an example another beast who ran through opponents. This isn’t the deciding factor as to why Vergo lost.
Doflamingo who is YC1+ even if you lowball hypes up his RHM as being unstoppable with even his own CoA not stacking up to his.
Both he and Vergo underestimated Law’s growth with his Op Op, little did they know the true extent of the ability and Law caught them off guard by him pulling out all the stops and using a mountain level slash that he NEVER attempts again since it was only against Vergo’s unstoppable Armament.
That mountain slash is comparable to attacks he used on Big Mom, huge AoE and DC included.
Fresh Vergo would’ve slaughtered Law and instilled the fear back into his brain. Doffy was already low diff’ing Law the same way he low diff’d Smoker and Luffy first encounters and Sanji.
Vergo’s true power was never fully seen as it was watered down and distributed among fodder before he lost to his own arrogance sadly. We only ever seen devastating snippets of his destructive bamboo but I’ll dive deeper into that another thread
