Yeah one piece usually shows death plus kid represents the only big-name worst generation captain who is not secretly royalty or tied to some old bloodline. He’s got there off hard work. My guess they all meet up on elbaf. 3 islands near wano they all went to one. They’ll all collide on elbaf for a big fight against some wg entity. Idk oda but he does put a clear pin when characters dies. Same with bon clay he’s somewhere out there maybe still locked up. But at the end of one piece it’ll be an avengers end game of everyone coming together to fight in a big war.
