Marco babysitting K&Q would be more impressive if they didn't fight him in their retarded zoan form without any knowledge of his powers. [This was written when phoenix Marco was choking zoan King and Queen] Regardless, even if they fought him at full power Marco would be able to hold them at bay for a while thanks again to his regeneration, before succumbing to them once that runs out. [You're welcome for the spoiler] No different from every fight he would have with a TT. Again, nothing impressive. Shanks crew is built to replicate Roger's crew, Beckman is the official VC, he's Shanks' Rayleigh. He is separated and > the other YC1. Katakuri unlike Marco has a decent offense when PIS doesn't block his Mogura. That leaves Marco and King. If King has decent swordsmanship Marco most likely falls to the bottom.
