Who's the weakest character from Dragon Ball who could clear the One Piece world?

Well, maybe those in verse match ups may seem silly, but I still find them funny to speculate sometimes. What would you say?

For me, BoZ Piccolo may be enough considering he had enough power to blow up the moon, while 23rd Budokai Piccolo already likely scaled up to island's level, similar to Whitebeard.

It seems like the strongest people/weapons in One Piece are island level. The government seems to have an ancient weapon that can instantly vaporize large islands, and that's been treated as the top level power. BoZ Goku/Piccolo should suffice.

I agree, but Whitebeard and Roger are country/continent tier, IMO. It would take someone like Nappa to defeat them.
