Luffy man handled Saturn, he just couldnt understand his regen haxx to make him stay down. Even did Saturn and Kizaru at the same time while trying to protect everyone including Vegapunk. That was way different than Sanji, Bonney, Kuma and who else managed, those guys got their butts properly whooped.
Absolutely no way Gunko takes out Bonney, Robin, Lilith, Nami together. Look at her frame. She can dish a couple of attacks out but can't take it, like most females in OP. Robin snaps her in two with ease, Nami utterly destroys her with Zeus, Bonney makes her 90 years old and crippled, Lilith does whatever.
This man gets it. They are likely not weak by any means but there are levels, mid diff and over as soon as Zoro gets serious and decides to end the fight no bandana style. Shamrock on the other hand and the presumed Beckman of HK is another thing, proper Luffy/Zoro opponents.
