kinda off topic, but why does Luffy seemingly do more damage to kaido when he turns his face into rubber? Doesn't rubber increase Luffy's durability?
Or is it that Luffy isn't turning kaido into rubber at all, since his powers technically aren't rubber, but rather those of the god Nika. Basically Luffy's elasticity helps him but hurts others when it is used on them(via awakening), because Nika somehow.
