It actually sounds like all 6 will be "needed" to catch his son. If they ALL manage to bring his son to the party, they ALL will have a chance to fight the All-Stars. However, the ONE that beats an All-Star will replace that respective person.
That's what the spoiler notes are implying at least.
This is why i don't get why people think Kaido's son is "weak" or something. It actually implies the opposite from Kings dialogue.
Yea that's what I thought as well at first and it certainly can be interpreted that way, but that would also mean that one of the All stars, if he's unlucky, would have to face a gauntlet or not?
Like what if everyone who's up to take that challenge out of the F6 wants to face the same calamity? :D
Obviously in theory this might be possible, when they can rest afterwards and all that, but under the recent circumstances, where Kaido aims at putting up a show for BM, this doesn't really add for me. Independent from the recent circumstances (the approaching war).
But I'd like to hear your thoughts about it.
BTW I aswell would prefer it if they, as a collective, would be the "son catching" troop. But there's the issue from above.
And I've just noticed that my view on it would potentially lead to an inner group rivalry. Questionable whether Oda aims at that.
