I agree, I’m most interested in seeing Yasopp. I mean he’s Usopp’s father, that alone makes him the most anticipated pirate in Shanks’ crew besides Shanks himself.
I think the end result would (mostly) be the same. Ace was just asking to be killed when he wanted to fight Akainu, so he still dies in some stupid attempt to prove himself. Whitebeard may or may not die depending on how much help he receives from the Straw Hats.
I watched Dragon Ball and Dragon Ball Z around the same time as I watched Naruto and Naruto Shippuden, then I got into Bleach, One Piece, and Yu Yu Hakusho.
