I wouldn't mind Big Mom at Elbalf but it's looking really unlikely either her or Kaido will ever be threats again.
If her crew really does pick her up and she isn't dead, maybe Smoothie could suck the lava out but even if that happened, not sure what would be left for the character. Attempting to fight at Elbalf after being defeated here is something but it's kinda desperate and a bit much and I'm not sure if she'll even be in a condition to try. If she's dead, I'll admit that isn't the best conclusion to her story but she has to be removed somehow I guess and the falling at the hands of the New Gen aspect of it is great.
Kaido's been in the lava for a week now, he seems done. I don't really mind if he came back and whatever that entails but after being punched into lava by a fist that went through his defenses and offense, seems too late to have him try stuff.
