Kaido was using maybe 20-30 percent of his potential until 1010. After Luffy mastered coc coating, he revealed the fighting style he was hiding. Then, with Luffy getting his last power up, he wanted to voluntarily tank Luffy's gigantic fist. After all, the concept called haki is a situation related to whose will is stronger.
