He removed his bandana:
Leaving aside that he's heavily coughing up blood, he took off his banada. He'll be sitting out the fight for a bit.
I agree. Does he have much stronger attacks though? This is a Kaido that was trying to kill Luffy.
I would say the Roof Five have given two Yonkou a solid medium difficulty fight.
Neither feats nor portrayal place Luffy above Zoro.
Oh, who's the original account?
