@TheAncientCenturion do you agree that "ancient zoan recovery" is total BS?
What ancient zoans have are high durability (defense) and high endurance (max HP), but not recovery / regeneration.
Durability highlight: Franky had problem and had to look for Sasaki's softest part. Luffy had problem penetrating Kaido's scale in act 1. Zoro had problem injuring King.
Endurance highlight: Jack not going down in 5 days at Zou although his men were down. Ulti in Onigashima. Sanji had problem KOing Queen.
But not recovery. It is never shown that any ancient zoans got injured but their wound is healing on panel. Nothing like that at all. Only Marco's fruit gets that benefit. If ancient zoan had recovery as the rumor said, then Marco's DF would also lost its specialty.
So, King and Queen's condition is still bad when they faced Green Bull. Not that different compared to when Zoro / Sanji defeated them. Although they are bandaged, no way their doctor is as good as Chopper too.
