I love seeing Oda parallel Luffy/Zoro with Joy Boy/Ryuma. I've gained more confidence in my theory that Zoro is Ryuma's son, sent to the future by Toki. The Samurai lost in time is going to decapitate the dragon over Wano, and turn Enma into a Black Blade to fulfill Oden's Will.
Black Beard is going to pick up Kaido's corpse with Moria (ruining Kaido's honorable death, and send Zombie Kaido to attack Wano to try to conquer it.
ZORO KILLS ZOMBIE KAIDO, BABY.
