I am hoping that Katakuri ends up explaining that he has an Awakened ability, which Luffy gets to learn more from. As Luffy did with CP-9, I expect the more he can encounter enemies of this type that he learns how to Awaken his own. So far I would think that his resulting ability would be similar to Doflamingo, being able to convert his surroundings. If Luffy would be able to do such a thing he would then be able to gain more speed, bouncing off other rubber objects, as well as making the ground bouncy for his opponenet.
