One funny thing in the Kid and Law combos versus Big Mom is that Oda always showed the effect of Kid's attack a chapter after it landed
- Punk crash was the cliffhanger of chapter 1030
And we only saw how much it damaged BM in the following chapter
- Punk Cornadio was the cliffhanger of chapter 1038
And now the spoiler say that Big Mom ended with broken bones
So looking at this, we'd probably only see the effect of Kid's ultimate attack in the next chapter, and considering it's supposed to be a finisher, it should be devastating
