Regarding Momonosuke's Devil Fruit, I think he can't bring out the full potential of it yet. The Chinese Dragons have control over weather and water (mostly moving waters such as waterfalls or rivers). So, maybe with some training, he might be able to do that as well. Though, such an amazing ability would be wastet on someone like Momo.
