One thing is for sure. Big Mom is done
- We already had a Kid and Law vs Big Mom chapter, and as we've seen in this war, every time we get a chapter title, the conclusion is coming soon afterwards
- Law and Kid's previous attack was mentioned to have broken a good part of Big Mom's bones before she used her soul powers to recover, a soul power that affects her lifespan that she already used before and ended up exhausted after a certain while, and she didn't take their ultimate attack at that point
Now however she took their ultimate attack back to back and thus if a far weaker combo broke a good part of her bones, it's highly likely she'd be done after this, all of this coincidating with Law's speech about her era ending there
So there are only 2 possibilities left for her imo. Either she'd be barely seen awake sometime later turning into O Linlin state or she's completely defeated
In either case, her relevancy as a potential nemesis of Elbaf disappeared, and the worse thing is that ultimately she ended up overshadowed by Kaido
