Lmao have you forgotten Law can teleport out of Onigashima?
He gets out of there, on top of his sub on top of the ocean, Krooms his sword all the way up to Onigashima and it’s GG.
And let’s not pretend Oda didn’t draw that with the hole scale to Onigashima in mind. Oda is not consistent with sizes mid battle, which is why diagrams like these are the best indicators of relative sizes.
