Wano arc is one of the arcs who has already the most important amount of important players and of the strongest characters inside it right after Marineford arc with most of the Worst Generation, Two Yonkos and their crews (or rather a portion of it in Big Mom's case) the former followers of Kozuki Oden, the samurais of Wano, the mink tribe and at least some of the Whitebeard Pirates being present in the arc.
And it may not be the end with other major players or strong characters coming to Wano later in the arc as well. Many on this forum (me included) believe that the marines will eventually come too, some that the Grand Fleet or at least a portion of it will arrive to Wano and others are speculated to come such as Weevil or the CP0.
So in your opinion whose additionnal characters or crews or organisations will find their way to Wano and add their degree of salt or spice in the story ? Who do you think is/are sure to come ?
