User blog:Onepiece2trill/Law and Kid how will they fight the logias

if law or kid were to fight one of the three admirals, how will they fight them. will oda give them haki of some sort, or will they use seastone weapons or their ability allows them to fight logias. i have just been wondering. also will any of the supernovas have haoshoku haki or just luffy. cuz gold rogers and whitebeard have it and they are rivals.
