I mean, I expect them to beat at least some fodders on these ships. Especially Nami should be able to wipe out several ships with a single lightning strike due to Zeus but here she is, hiding as usual, lol.
I don't know what Oda sees in these joke moments. They are way too overused, not even a bit funny and just unfitting for a sea battle in the New World, at the territory of an effing Yonko.
And at worst: He only portrays the weak trio as huge jokes when they are supposed to be powerful enough against fodders. They are straw hats as well, part of the crew of the future Pirate King. Heck, what did they do during their timeskip training? It's all meaningless if Oda keeps portraying them as weak cowards ffs.
