Well this is a just a small theory, but it seems like they know how to kick really really well. If only using the dancing style and Bon clay (Mr 2) as foundation evidence, we could see Sanji learning how to make his kicks even stronger. Oda doesn't know how to let himself be lazy when writing anything. There's bound to be some kind of upgrade from everyone coming. Besides, why would Kuma send some of them to places that can't help them and others to places that when they're leaving, they're super strong from?Originally Posted by Assertn
It wouldn't make any sense.
