Dover was the first to win Luffy's domineering fist at the top of the palace. However, for a master like Dover, such damage is almost negligible.

Unfortunately, Dover.
Don't forget, the opponent's strength can reflect the protagonist's ability. If Dover is vulnerable, how can we show Luffy's strength?
