A looooooooooooooot of assumptions here
Ju Peter is number 1, Saturn is number 5 - these are the numbers that would lend to the strongest Gorosei if the numbers are relevant at all
Warcury's shown Haoshoku Haki, and that's it. It's almost 100% certain they will all have all the same Haki abilities as eachother.
Also, what is the need to recreate the mountain god incident?
Look I'm not saying it has to happen, just that she already has a perfect matchup if she does join.
As far as warcury, it's more that he's the one in the middle, acts as if he's the one in charge, and his name is literally top man. Maybe he's not the strongest, I just said presumably.
All I'm saying is that if we already know the endgame opponents, it helps a newcomers case if there's a good matchup for them.
You got a point. But then I remember that Sanji vs King aerial battle didn't happen either
True, but like I said, it's just the fact that there are opponents that make sense for her in both the endgame enemy factions. Also Sanji vs King was always a pipe dream. Zoro will fight the sword guy every single time.
