And he probably has more techniques up his sleeve to fight emperors that he hasn’t shown yet. Plus, he said that he could defeat Katakuri if he made him waste his Haki but won’t do it. In otherwords, he’s trying more than just to exhaust the enemy and win: he wants to defeat the enemy at his best and wants to learn from the experience as well. He’s using this fight to get stronger.
